CentOS6 and tilde expansion
by isdtor 05 Jan '12

05 Jan '12

Set up NIS and autofs on this new CentOS6 box, but it seems tilde expansion no longer works in bash? [root@frodo ~]# cd ~john -bash: cd: ~john: No such file or directory [root@frodo ~]# cd /home/john [root@frodo john]# pwd /home/john [root@frodo john]# It still works in t/csh: [root@frodo ~]# /bin/csh [root@frodo ~]# cd ~john [root@frodo ~john]# pwd /home/john [root@frodo ~john]# I couldn't find anything in the bash man page that suggests this feature needs explicit configuration.

A simplistic parental-control setup
by Marko Vojinovic 05 Jan '12

05 Jan '12

I am looking at the simplest (implementation-wise) solution to the following problem (on CentOS 6.2): I have a list of web addresses (like http://www.example.com, https://1.2.3.4/, etc.) that should be "forbidden" to access from a particular host. On access attempt, the browser should be redirected to a local web page (file on the hard disk) with the explanation that those addresses are forbidden. The possible ways of disallowed access include: * typing www.example.com or http://1.2.3.4/ in the browser * typing www.example.com/anyfolder/somefile.html in the browser * clicking on www.example.com when listed as a link on some other web site (say, Google search results) * nothing else. The last point above assumes that the users will never try any other method of accessing the site. These user's knowledge about computers in general is known to be elementary, so I don't need protection against geniouses who can figure out some obscure way to circumvent the lockdown (and please don't tell me that this is an irrational assumption, I know it is...). If possible, all this should be on a "per user" basis, but if implementing it system-wide would be much simpler, I could live with it. :-) The point is that I need a simple, easy-to-implement, easy-to-configure and easy-to-maintain solution for this particular usecase. What I don't need is some over-engineered solution that covers my usecase along with a whole bunch of stuff I will never need, and takes two months to configure properly. It should also be F/OSS, preferably included in CentOS repos or elsewhere. Or alternatively I could go along with manually setting up a bogus httpd/dns/iptables configuration which would do all this, but I have a feeling that it would not be the easiest thing to maintain... I'd appreciate any suggestions. :-) Best, :-) Marko

dhcp lease-time
by Timothy Murphy 05 Jan '12

05 Jan '12

Why is the default lease-time set to only 10 minutes (600 seconds) in /etc/dhcp/dhcpd.conf (CentOS-6.2) as distributed? Why is not set to a much longer time? Is there any disadvantage in doing that? Or conversely, is a short lease-time safer in some way? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

Cannot use kickstart file to install CentOS 6.2 into a blank harddisk
by lee_yiu_chung＠yahoo.com 05 Jan '12

05 Jan '12

I am trying using a kickstart file to install CentOS 6.2 into a new virtual machine (the MBR sector of the harddisk is all zero), however I found that the installer cannot go through the harddisk partition. It failed after I chose "Use All Space" at harddisk partition option. The error message is: http://anony.ws/i/bMcTJ.png "You have not defined a root partition (/), which is required for installation of CentOS to continue. You have not created a/boot/efi partition (note: I am using BIOS, not (U)EFI) This can happen if there is not enough space on your harddrive(s) for installation." However, if I create a blank MBR partition table before before CentOS installation, then there is no problem. The same kickstart file works for CentOS 6.1 with blank harddisk. (with url parameter changed of course) Below is the kickstart file I used (between dash lines) ------- url --url="http://ftp.twaren.net/Linux/CentOS/6.2/os/i386/" interactive timezone Asia/Hong_Kong firstboot --enable ------- Steps to reproduce: 1. create a new virtual machine with blank harddisk image (or, a real blank harddisk) 2. boot the netinstall iso 3. at boot menu, press tab and append ks=<kickstart_file_location> and press enter to boot 4. go through the boot option as usual until harddisk partition options 5. Choose "Use All Space" at harddisk partition options 6. error occurs

fail2ban won't die
by Timothy Murphy 05 Jan '12

05 Jan '12

If I lose my broadband connection here (Italy), and try to re-boot the computer (CentOS-6.2), the shutdown hangs at fail2ban. Normally there is no problem re-booting; it only happens if the network has gone down. It may just be an extraordinarily long timeout. Has anyone experienced this? And is there anything one can do about it? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

ASP running on a Linux Machine
by Jonathan Vomacka 05 Jan '12

05 Jan '12

Good morning all, I currently have a website that was written in ASP back in 1999. The system is currently running Windows 2003 Server with MsSQL. Before everyone flames me for being in the wrong place, I was wondering if there is a way to allow centos to run old ASP code? I know years ago this wasn't possible without a program like ChiliASP, but noow I heard rumor that apache might have a plugin to allow it to read ASP. I am unsure if there is an apache solution, or other solution like nginx/lighttpd that runs ASP. Any information you guys could provide would be great. I do appreciate your help in advance PS. I will need to convert the mssql data to mysql, is there any good program that will convert this? I understand that this question is probably inappropriate for this e-mail thread but maybe someone could shoot me a quick suggestion.

PHP 5 bug?
by Lists 04 Jan '12

04 Jan '12

I'm using EL6 with all updates applied and getting bit by a PHP5 bug that was fixed a year and a half ago... https://bugs.php.net/bug.php?id=52534 EL6 ships with php 5.3.3, which was released prior to the bug fix. What are the chances that this fixed bug can be reported/fixed upstream at the prominent North American Linux Vendor? Here's sample code that demonstrates the problem: function CheckBug52534(){ $check = array(1 => 'a', -1 => 'b'); $str = var_export($check, true); $str = "\$a=$str;"; eval($str); if (!isset($a[-1])) return true; } echo (Checkbug52534()) ? "has it" : 'not found'; -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

local repositories
by m.roth＠5-cent.us 04 Jan '12

04 Jan '12

I need a clarification to the documentation. My manager added a 6.2 repo; however, when I try doing pxeboot installs, it fails, asserting that it can't find the group info. Another admin I work with thinks it's not really what it's failing in, and notes that it 404's on images/updates.img and images/product.img. We *think* that's irrelevant and ok. What is not clear to me is when we run createrepo, what directory you need to be in at the time you execute it. mark

Request for suggestion of a SCM package for Centos 6
by Rajagopal Swaminathan 04 Jan '12

04 Jan '12

Greetings, I have a freshly installed Centos 6.2 box with everything (darn! I had to hand select each and every package -- IIRC one of the fedora versions had a nice "select all" checkbox). My questions are: 1. Can somebody suggest a way to select all packages while installing from DVD? 2. Can somebody suggest a versioning system which integrates well with a bug tracking system (I had installed Subversion with Trac more than a couple of years back on Centos 5.x for some customer -- but it was a kludge as it required many things not provided with stock Centos 5.x like some python some php 5.2 etc.) TIA, -- Regards, Rajagopal A proud promoter of Centos for over 5 years

vmware fusion display auto-size problem
by Monty Shinn 04 Jan '12

04 Jan '12

Greetings. I am running vmware fusion 4.1.1 on a OSX host. Centos6.2 is a guest. The box is a macbook laptop running leopard. Before upgrading to 6.2, the display auto-resize (or auto-fill) was working fine. After 6.2, it has stopped working. Centos is fully updated to 6.2. I have tried to install the vmware drivers from the repository (via yum), and yum reports I have the latest. Vmware reports I have the latest version of app and linux tools. I have uninstalled and re-installed vmware tools to no avail. During the vmware tools install it returns a statement that it does not have drivers for x. Anybody else come across this? Google and vmware sites either do not have any info, or I am asking the wrong question. This being my first foray into vmware, is it advisable not to run updates until needed? What is best practice in this config? Thanks in advance for your help. Monty

vsftpd log issues
by Timo Neuvonen 04 Jan '12

04 Jan '12

I have an up-to-date CentOS 6 with reasonable amount of ftp activity (a dozen of network cameras uploading images every second 24x7). The first issue was that the whole /var filesystem was about to get full, because of huge ftp daemon log. vsftpd.conf says: # You may override where the log file goes if you like. The default is shown # below. xferlog_file=/var/log/vsftpd.log Ok, the above works now. But while the setting was (by default) commented out, the default wasn't /var/log/vsftpd.log but /var/log/xferlog which was growing without limits (it was over 6 GB when I first time noticed the problem) since logrotate tried to rotate vsftpd.log -rw------- 1 root root 0 Dec 31 03:07 vsftpd.log -rw------- 1 root root 39134459 Dec 31 12:19 vsftpd.log.1 -rw------- 1 root root 433305200 Dec 30 22:03 xferlog Now, after uncommenting the log file setting line in the conf the next issue is, that logrotate does rotate the log files (the old one gets .1 postfix added to its name and a new file is created), but it still keeps writing to the original file (which is renamed now) In the ls -l listing above: - vsftpd started to write log vsftpd.log around 10pm last night (when I uncommented the log setting from the conf and restarted the daemon, until that it was logging to xferlog) - during the night logrotate has changed the name of the existing log file to ...log.1 but now, several hours later, this renamed old file is still used for logging, and the new ...log file remains empty! Is there some simple option in logrotate's conf that could change this behaviour? Or how to fix this. There must be many others who already have run into this issue. Regards, Timo

Passwords apparently stopped working.
by James B. Byrne 04 Jan '12

04 Jan '12

I encountered a couple of strange events with respect to password authentication this morning. Two of our staff were unable to login onto several systems using their usual passwords. Both users had last logged in on these hosts using their accounts and passwords on Friday past. The two accounts could not log on to any of the servers for which they had access and the message log on each showed that access was denied for a failed password. The systems involved were running either CentOS-4.9 or CentOS-5.7. So, the effect was uniform across multiple hardware and software platforms. I also checked these accounts against our warm backup machine and encountered the same problems for both. I verified that the passwords being used were correct for the accounts. I also verified that neither of passwords had been reset in some months and there were no expiry dates set for the accounts. I would accept the coincidence of both forgetting their passwords except for the fact that each had kept a record of their password in their wallets and I was able to confirm those values against our records as well. Resetting both the passwords to their current values using the passwd utility on each system corrected the problem insofar as the users were concerned. However, I am somewhat perplexed as to the reason for their passwords to stop working in the first place. Is anyone here aware of any reason why this might happen? -- *** E-Mail is NOT a SECURE channel *** James B.

'last' command doesn't include ssh connections made by this perl script?
by Bennett Haselton 02 Jan '12

02 Jan '12

My home machine has IP 50.54.225.130. I have (for the purposes of this experiment) one remote machine at www.peacefire.org (69.72.177.140) and another at www.junkwhale.com. When I'm logged in to peacefire, I run this perl script to open an ssh connection to junkwhale and run a command: my $hostname="www.junkwhale.com"; my $server_password = "[redacted!]"; use Net::SFTP; use Net::SSH::Perl; my $ssh = Net::SSH::Perl->new($hostname); $ssh->login("root", $server_password); my($stdout, $stderr, $exit) = $ssh->cmd("pwd"); print "Stdout: $stdout\n"; print "Stderr: $stderr\n"; If I then log in by ssh to junkwhale from my home computer and run grep 'Accepted password' /var/log/secure the last two lines are: Jan 2 13:23:17 e2180-20059 sshd[12635]: Accepted password for root from 69.72.177.140 port 1023 ssh2 Jan 2 13:23:28 e2180-20059 sshd[12684]: Accepted password for root from 50.54.225.130 port 52484 ssh2 which is correct -- the first line is from the perl script connecting from Peacefire (69.72.177.140) and the second line is for the connection I just opened from my home computer. If, however, I run the "last" command, the first two lines are just: root pts/0 50-54-225-130.ev Mon Jan 2 13:23 still logged in root pts/0 50-54-225-130.ev Mon Jan 2 01:52 - 01:52 (00:00) In other words, the "last" command doesn't list the connection opened up by the Perl script. It only lists the times that I've connected by opening a connection manually with my SSH client. Presumably that means the connection with the perl script is not being logged in /var/log/wtmp , although the contents of the file are binary so I couldn't make much sense of them directly with a screen dump. This makes me wonder two things: 1) What is the difference, from the server's point of view, between the connection opened by the script and the one opened by my ssh client; and 2) More seriously, whatever it is that's different about the connection opened by the perl script, isn't it a bug that that connection is not recorded in wtmp? If admins frequently use the "last" command to determine who has logged into the server, couldn't an attacker do this to avoid detection? Bennett

raid resync deleting data?
by Nathan 02 Jan '12

02 Jan '12

Hello, I have a c5 box with a 6 drive raid 6 array. I was going away over Christmas so I was shutting the machine down, I noticed a raid resync (on the raid 6 array) so i stopped it, using the command # echo "idle" > /sys/block/md5/md/sync_action then shut the machine down. A week later I turned the machine on and started copying data to it around 24 hours later a raid resync occurred and wiped all the new data I had copied to it. To me this seems broken, is it because I manually stopped a previous resync that it got in this state? Any ideas? As for log messages there is nothing in the /var/log/messages file, only Jan 2 19:38:39 bolivia kernel: md: syncing RAID array md5 Jan 2 19:38:39 bolivia kernel: md: minimum _guaranteed_ reconstruction speed: 1000 KB/sec/disc. Jan 2 19:38:39 bolivia kernel: md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for reconstruction. no other errors or anything. Thanks Nathan

what percent of time are there unpatched exploits against default config?
by Bennett Haselton 02 Jan '12

02 Jan '12

Suppose I have a CentOS 5.7 machine running the default Apache with no extra modules enabled, and with the "yum-updatesd" service running to pull down and install updates as soon as they become available from the repository. (Assume further the password is strong, etc.) On the other hand, suppose that as the admin, I'm not subscribed to any security alert mailing lists which send out announcements like "Please disable this feature as a workaround until this hole is plugged", so the machine just hums along with all of its default settings. So the machine can still be broken into, if there is an unpatched exploit released in the wild, in the window of time before a patch is released for that update. On the other hand, at any point in time where there are no unpatched exploits in the wild, the machine should be much harder to break into. Roughly what percent of the time is there such an unpatched exploit in the wild, so that the machine can be hacked by someone keeping up with the exploits? 5%? 50%? 95%? Hopefully this is specific enough that the answer is not "it depends" :) , an actual numeric answer should exist -- although I don't know if anyone has ever tried to work it out. But if not, then what's a good guess, based on observing how frequently root exploits are released in the wild, and how long the patches usually take. Bennett

(Tried sending this before but it doesn't look like it went through; apologies if you're seeing it twice.) OK, a second machine hosted at the same hosting company has also apparently been hacked. Since 2 of out of 3 machines hosted at that company have now been hacked, but this hasn't happened to any of the other 37 dedicated servers that I've got hosted at other hosting companies (also CentOS, same version or almost), this makes me wonder if there's a security breach at this company, like if they store customers' passwords in a place that's been hacked. (Of course it could also be that whatever attacker found an exploit, was just scanning that company's address space for hackable machines, and didn't happen to scan the address space of the other hosting companies.) So, following people's suggestions, the machine is disconnected and hooked up to a KVM so I can still examine the files. I've found this file: -rw-r--r-- 1 root root 1358 Oct 21 17:40 /home/file.pl which appears to be a copy of this exploit script: http://archive.cert.uni-stuttgart.de/bugtraq/2006/11/msg00302.html Note the last-mod date of October 21. No other files on the system were last modified on October 21st. However there was a security advisory dated October 20th which affected httpd: http://mailinglist-archive.com/centos-announce/2011-10/00035-CentOSannounce… https://rhn.redhat.com/errata/RHSA-2011-1392.html and a large number of files on the machine, including lots of files in */ usr/lib64/httpd/modules/* and */lib/modules/2.6.18-274.7.1.el5/kernel/* , have a last-mod date of October 20th. So I assume that these are files which were updated automatically by yum as a result of the patch that goes with this advisory -- does that sound right? So a couple of questions that I could use some help with: 1) The last patch affecting httpd was released on October 20th, and the earliest evidence I can find of the machine being hacked is a file dated October 21st. This could be just a coincidence, but could it also suggest that the patch on October 20th introduced a new exploit, which the attacker then used to get in on October 21st? (Another possibility: I think that when yum installs updates, it doesn't actually restart httpd. So maybe even after the patch was installed, my old httpd instance kept running and was still vulnerable? As for why it got hacked the very next day, maybe the attacker looked at the newly released patch and reverse-engineered it to figure out where the vulnerabilities were, that the patch fixed?) 2) Since the */var/log/httpd/* and /var/log/secure* logs only go back 4-5 weeks by default, it looks like any log entries related to how the attacker would have gotten in on or before October 21st, are gone. (The secure* logs do show multiple successful logins as "root" within the last 4 weeks, mostly from IP addresses in Asia, but that's to be expected once the machine was compromised -- it doesn't help track down how they originally got in.) Anywhere else that the logs would contain useful data?

Checkinstall rpm for CentOS-6 x86_64?
by James B. Byrne 01 Jan '12

01 Jan '12

I cannot seem to find a checkinstall rpm package for CentOS-6 or one for x86_64 more recent than CentOS4. When I try to build it locally from the most recent source I can find, c.2006, I get build errors having to do with size constants either missing or improperly defined. Does anyone have a source for an rpm of this package that runs on CentOS-6_x86_64 or can recommend a replacement for it? -- *** E-Mail is NOT a SECURE channel *** James B.

Dear All, I just got a new server with the following specifications: motherboard : Intel S5500BC CPU : Xeon Quad Core 2.6Ghz RAM : 8GB HDD : 4 x 2TB SATA with configured raid 10 using raid embedded server. The problem is the centos installer can't detect raid virtual disk. I can't find any log error with the following error messages during installation process: Disks sda, sdb, sdc, sdd contain BIOS RAID metadata but are not part of any recognized BIOS RAID sets. I'm already use search engine to find the information regarding to this issue, but I can't find the solutions for CentOS.

why not have yum-updatesd running by default?
by Bennett Haselton 29 Dec '11

29 Dec '11

Ever since someone told me that one of my servers might have been hacked (not the most recent instance) because I wasn't applying updates as soon as they became available, I've been logging in and running "yum update" religiously once a week until I found out how to set the yum-updatesd service to do the equivalent automatically (once per hour, I think). Since then, I've leased dedicated servers from several different companies, and on all of them, I had to set up yum-updatesd to run and check for updates -- by default it was off. Why isn't it on by default? Or is it being considered to make it the default in the future? Power users can always change it if they want; the question is what would be better for the vast majority of users who don't change defaults. In that case it would seem better to have updates on, so that they'll get patched if an exploit is released but a patch is available. If the risk is that a buggy update might crash the machine, then that has to be weighed against the possibility of *not* getting updates, and getting hacked as a result -- usually the latter being worse. After all, if users are exhorted to log in to their machines and check for updates and apply them, that implies that the risk of getting hosed by a buggy update is outweighed by the risk of getting hacked by not applying updates. If that's true for updates that are applied manually, it ought to be true for updates that are downloaded and applied automatically, shouldn't it? Bennett

NFS options in fstab
by Daniel Bird 29 Dec '11

29 Dec '11

Hi All, I've a quick question I'm hoping someone can help out on; One of our NFS servers has an intermittent hard lock problem under high load. This is a CentOS 5.7 box. It's due for replacement sometime next year. However... The issue is when this box dies the boxes that mount the NFS exports have trouble with the mount and some processes time out casing the system mounting the file system to become unresponsive also. Of course un-monuting the file system with -l fixes it. This is an example of our current mount options in fstab hostname:/share1/ /mountpoint nfs rw,intr,soft,bg 0 0 The question is, what (other) options should we be using to allow the mounting server to ignore/fail/timeout the mount, or at least continue normal processing, when the NFS server packs up? FYI we can't move to NFS4 since we've some old boxes running Solaris 8 mounting this filesystem also, which cannot be upgraded Solaris 10 to support v4. All the best Dan

asus-wmi.ko for Asus G73Sw running CentOS 6.2
by Rob Kampen 29 Dec '11

29 Dec '11

Hi List, Just loaded our favorite OS onto my new ASUS laptop. Practically everything worked out of the box - I used the live DVD to check things out and installed from there. I have followed http://forum.notebookreview.com/asus-gaming-notebook-forum/553474-g73-asus-… to get suspend working and also to get function keys working for LCD screen backlight controls working (Fn F5 and Fn F6). Upon further searches I find that there is a kernel module asus-wmi.ko available in some distros that also allows some of the other Asus functions to operate - of particular interest is the keyboard backlight (Fn F3 and Fn F4) as well as the master backlight on/off key to function. Question, does anyone know where and how to locate this (asus-wmi.ko) and get it functioning under CentOS 6.2? I am prepared to set up the required build environment - but need some assistance as this is really at the limits of my experience. I have rebuilt the kernel to remove patches with some success previously and will have to dust off this knowledge if required. TIA

Ad integration with centos 6

Can anyone point me to a tutorial on using Active Directory to authenticate a centos 6 server? I just want to use it to authenticate, ssh and restrict access to a particular ad group. I prefer to use the lightest method possible. I know you can use ldap, or winbind, etc. I have been trying to follow the ones I have been googling, but none of them seem "quit complete. My issue is that I have no ldap experience. Dnk

Is Biarch with 6.x now dead?
by Michael Lampe 28 Dec '11

28 Dec '11

I'm experimenting with 6.2 now. Things seem to be really great so far! Distribution closure is one of my favourite pets. So I tried to install everything. I found only one problem, but that's another (minor) thing. But I found almost nothing under /usr/lib. So, Biarch is really dead? Funny! A couple of years back, I finally opted for CentOS instead of Debian just because of Biarch ... I'm getting real old ... -Michael

Hyper V integration question
by Dvorkin, Asya 27 Dec '11

27 Dec '11

Hello everyone, I have Hyper V integration working properly, but needed to do an update to 2.6.18-274.12.1.el5-x86_64. Since then, it no longer works. As discovered previously, one needs to rebuild Hyper V Integration tools due to the kernel panic. http://www.sudonym.com/398/kernel-panic-after-yum-update-centos-with-hyper-… Done. But I'm getting an error message: "Your system DOES NOT support the timesource driver" when running make. adjtimex is installed - adjtimex-1.20-2.1. Any ideas? I've successfully followed the same steps in the past, but right now they are just not working. Thank you! Asya

Plymouth "Failed to read image"
by 夜神　岩男 27 Dec '11

27 Dec '11

I'm trying to learn more about Plymouth, but am having trouble finding sufficient documentation on it. After a rebuild of Plymouth with a few theme changes, I am getting an error message on boot "Failed to read image" and then it gives me the grub screen to boot one of the three kernels installed. Boot works fine and I actually see the proper splash once I select a kernel. Changing themes works, etc. The single problem is that weird message about image read failure. So my question: Since Plymouth actually is working fine after the 5 second delay, just what image is it that can't be read? Is this a message about, say, the "background image" for the menu (the screen background *is* black, actually) or the "ramfs boot image" which apparently works just fine after a moment? Perhaps the error message is just confusing me. If it is just the background image, then what is not valid about the splash.xpm.gz now? I've reduced it to 14 indexed colors, 640x480 resolution (which I thought were the criteria?).

VMware tools not installing init.d script
by Brian McKerr 27 Dec '11

27 Dec '11

Has anyone else seen this on Centos 6.x x64? Running vSphere 5.0 and I install tools from the VMware tar.gz file with ' vmware-install-tools.pl -d' it seems to do all the usual/right things. Once completed there is no 'vmware-tools' listed in 'chkconfig --list'. A reboot of the box leaves vmware tools not running. I have tried completely uninstalling tools and re-installing, not difference. Cheers.

gnome keyring
by Jerry Geis 26 Dec '11

26 Dec '11

I am having an issue I have not ran into before... I set my box to "auto" login by changing the file: more /etc/gdm/custom.conf # GDM configuration storage [daemon] AutomaticLoginEnable=true AutomaticLogin=silentm TimedLoginEnable=true TimedLogin=silentm TimedLoginDelay=0 [security] [xdmcp] [greeter] [chooser] [debug] It does auto login - however then when I try to VNC into the box I get the message about the "gnome remote desktop enter password for default keyring to unlock". I do have a VNC password set. I did some searching but the things I found did not make a difference. Any thoughts? Jerry

Mystery of email authentication
by Timothy Murphy 26 Dec '11

26 Dec '11

I'm trying to setup sendmail/dovecot on a new server running CentOS-6 (well, CentOS-6.2 now). Everything seems to go well, but when I run fetchmail I get this warning: ------------------------------------ [tim@grover ~]$ fetchmail imap.maths.tcd.ie fetchmail: Warning: the connection is insecure, continuing anyways. (Better use --sslcertck!) ------------------------------------ I should say that everything runs fine on a CentOS-5.7 server, and as far as I can see the setup on the new server is the same. Under CentOS-5.7 I don't get the same warning: ------------------------------------ [tim@helen ~]$ fetchmail imap.maths.tcd.ie fetchmail: No mail for tim at imap.maths.tcd.ie ------------------------------------ If I do add --sslcertck (as suggested) I get the response: ------------------------------------ [tim@grover ~]$ fetchmail --sslcertck imap.maths.tcd.ie fetchmail: Server certificate verification error: self signed certificate fetchmail: This means that the root signing certificate (issued for /C=IE/ST=Dublin/L=Dublin/O=School of Mathematics, Trinity College, Dublin./OU=Automatically-generated IMAP SSL key/CN=imap.maths.tcd.ie/emailAddress=postmaster(a)maths.tcd.ie) is not in the trusted CA certificate locations, or that c_rehash needs to be run on the certificate directory.

kernel panic/abort during boot
by fred smith 26 Dec '11

26 Dec '11

Just did an in-place update from 6.1 to 6.2 on my eeepc 901 (Atom CPU). during boot, (if I hit ESC to see the boot messages) it says "starging udev" then nothing else for a few seconds, then a huge register dump scrolls by. it's too big to see the beginning of it. If I boot from the prior kernel and look in /var/log/messages, I don't see any evidence of the failed boot. I've seen the other thread titled "kernel panic", and it seems to be due to a missing initramfs, but there is an initramfs for 2.6.32-220.el6 already in /boot, so I don't think that would be the problem. Can anyone suggest how I would isolate what's going on here? -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------
