Inquiry:External USB modem and Remote PC Access?
by hadi motamedi 27 Oct '09

27 Oct '09

Dear All Please be informed that I checked for the presence of internal modem on my CentOS server , as the followings : #dmesg |grep -i modem #lspci |grep -i modem #lshw |grep -i modem According to the output , it seems that my CentOS client does not contain internal modem . So I decided to add external USB modem and make use of an PCAnyWhere like application that enables for Remote PC Access . Can you please do me favor and let me know how can I add the external USB modem to my CentOS host and please propose for an PCAnyWhere like application that can be installed on my CentOS client and enables for remote dialup connection (as the PCAnyWhere does for the MS Windows clients) ? Let me thank you in advance Regards H.Motamedi

Madwifi drivers afeter 2.6.18-128.
by Alessandro Ren 27 Oct '09

27 Oct '09

I have a atheros wiifi card on my Centos 5 that I use as a access point using hostapd. I noticed that after the upgrade to kernel 2.6.18-128 or above, the atheros driver comes with the kernel, ath5k, and it does´t let hostpad ou iwconfig set master mode on the card. Up to kernel 2.6.18-92 is workedd just fine using madwifi from rpmforge. Any ideas on that? Tks. __________________________________________________

Running SSH on a different port
by ML 27 Oct '09

27 Oct '09

HI All, With my new firewall in place, it has opened my eyes to how much traffic gets blocked in a single day and also what are the most active rules. I get *a lot* of requests for port 22. How does one switch ssh ports? What is a good port to use? What ramifications does it have when I need to ssh in? Is it as simple as ssh user@hots:port? Best, -ML

Need some help with logwatch.
by James B. Byrne 27 Oct '09

27 Oct '09

I am trying to get a logwatch summary emailed to a central address from a cron job. The tasd was copied verbatim from a system which does this already. Both are shown below. host1 crontab -l as root 45 7 * * * /usr/sbin/logwatch --service http --service imapd --service pop3 --service sshd --service vsftpd --service zz-disk_space --service zz-network --service zz-sys --mailto support(a)harte-lyne.ca host2 crontab -l as root 45 7 * * * /usr/sbin/logwatch --service http --service imapd --service pop3 --service sshd --service vsftpd --service zz-disk_space -- service zz-network --service zz-sys --mailto support(a)harte-lyne.ca #Logwatch summary My problem is that only the first gets delivered to support(a)harte-lyne.ca. The second gets delivered to root(a)host2.harte-lyne.ca and not to support. It has been a considerable time since I dealt with logwatch on the first machine and I cannot remember is there was any special configuration of logwatch itself to enable this to happen. Does anyone know what I might be overlooking? The curious thing is that if I cut and paste the host2 cron job entry into a terminal window that is logged in as root on host2 then the logwatch report goes to support as I intend. -- *** E-Mail is NOT a SECURE channel *** James B.

5.4 DVD
by m.roth＠5-cent.us 27 Oct '09

27 Oct '09

I admit I wasn't following the screaming and yelling about 5.4, so excuse me if this has been answered.... My boss tells me he wants me to start rolling out 5.4. I want to d/l & burn a DVD... but when I looked at a number of mirrors, the .iso is from 1 Oct, while the CD .iso's are from the 14th... yet 5.4 was officially announced the other day. Am I missing something, or do the mirrors have a pre-release DVD .iso, with no fixes in the last three weeks, or ...? mark

CentOS 5.4 .x86_64 and perl.i386
by Gregory P. Ennis 26 Oct '09

26 Oct '09

To All, Thanks to the CentOS guys for 5.4; sure appreciate your work. I have one question. I had to remove perl-5.8.8-18.el5_3.1.i386 on two x86_64 machines in order to get perl.x86_64 4:5.8.8-27.el5 to update. Does this represent a change from 5.3 to 5.4 and should I be concerned about the loss of perl-5.8.8-18.el5_3.1.i386. So far I have not found anything broken. Greg Ennis

Upgrading CentOS 5.3 from local mirror
by Jonathan Moore 26 Oct '09

26 Oct '09

Good afternoon folks. Earlier today, I started upgrading a few of our servers to 5.4 based on input from the list. So far, all has gone well. I have about 6 servers (not very many, but still) that need to be upgraded. Instead of taking precious bits from the mirrors for each upgrade, I was curious if I could rsync the 5.4 directory from a local mirror, and configure yum to use that repo, if it would upgrade without issues? Would I need anything other than the 5.4 folders to do the upgrade? -jonathan

mismatch_cnt after 5.3 -> 5.4 upgrade
by Devin Reade 26 Oct '09

26 Oct '09

Saturday I did an upgrade from 5.3 (original install) to 5.4. Saturday night, /etc/cron.weekly reported the following: /etc/cron.weekly/99-raid-check: WARNING: mismatch_cnt is not 0 on /dev/md0 md0 holds /boot and resides, mirrored, on sda1 and sdb1. md1 holds an LVM volume containing the remaining filesytems, including swap. The underlying hardware is just a few months hold, has passed the usual memtest stuff, and has been running 5.3 well for a few months. I'm *guessing* that due to the timing, this is related to the upgrade. I have to admit that I forgot myself and instead of doing the glibc updates as recommended, I only did: yum clean all yum update yum rpm -e --nodeps perl-5.8.8-18.el5_3.1.i386 (see today's perl thread) yum update perl.x86_64 yum update shutdown -r now I've taken a backup of /boot dump after the upgrade, but have not yet reenabled normal backups. My hunch is that something in the upgrade process touched sda1 but not sdb1, and that removing sdb1 from the mirror and reattaching it for resync would be sufficient, however I was looking for comments on this from anyone with experience or opinion on the matter. Googling the issue doesn't seem to turn up any recent related results. Also, could the upgrade have touched the bootblock on sda1 but not sdb1 and thus trigger this problem?

weird mac address
by Janez Kosmrlj 26 Oct '09

26 Oct '09

Hi, I have an interesting problem. I have a centos server connected to our dmz zone. For security reasons our network department limited the number of mac addresses that can connect to the port on the switch. And since we are running vmware server on top on centos and a windows virtual machine inside of it, the number of mac addresses that can connect to this port is two or the switch blocks all traffic on this port. And now comes the problem. The port blocks almost immediately. After some investigation we found out, that we have actually 3 addresses communicating from this port. One that belongs to eth-0 and is ibm specific (the server is an IBM x3550 and every mac starts with the vendor code), one that belongs to the virtual machine and is Vmware specific and then we have another mac address that is IBM specific. I can't find where this traffic comes from. I traced the traffic with Wireshark and found, that this mac address creates a DHCP discover every 64 seconds. I first checked if this mac adress could be from the second network card, that is not connected with a cable nor is the device enabled, but it doesn't and the mystery mac is completely different from the network cards macs on the last 6 characters (the two on-board cards macs are different only on the last character). Then I tried searching the logs and /etc for any occurrence of this mac address, but I can't find anything. Then we tried to isolate the server, so I connected it directly to my laptop and run the trace again to see if this packet comes from outside and is then redirected back out on Vmware's virtual switch (since it's a broadcast packet, this could be somehow possible). But everything indicates that this packets are generated on this server. In the meantime we increased the number of mac addresses to 3, but after a while we got a packet from a fourth IBM mac address, that again doesn't belong anywhere. It was similar to the mystery mac (it was only different on the last two characters) and the switch blocked the port in the middle of the night. but this was a one-time occurrence for now. Does anyone have an idea what is happening or where i should look for the mystery mac address. thanx Janez

XFS might be available for i686 from the CentOS Plus repository.
by Rainer Traut 26 Oct '09

26 Oct '09

Hi, the topic is an excerpt of the 5.4 release notes and raises a question. I have a i386 server here, that has been running for nearly two years with xfs module from extras repo. When lookin at the module it was build against 2.6.18-92.1.13.el5. Question is, is it still safe to use this module with 5.4? Or should I switch back to a CentosPlus kmod and an older kernel? Rainer

OT: pager pay
by Alan McKay 26 Oct '09

26 Oct '09

Hey folks, I'm trying to compare my small company's policy against other companies out there. We pay 10% of your per-hour salary equivalent per every hour you carry it, whether it goes off or not. So for example someone making $55K/year works out to about $27 / hour (I think), so they'd get $2.70 for every hour they carry the pager outside of regular work hours. We are a company of about 25 people. My old employer Nortel still does it this way : - $27.50 for every 8 hour shift you carry it, outside of regular work hours. - any page is billed at time-and-a-half, minimum 1 hour billed - any page requiring you to go into work, is billed at time-and-a-half with a 3 hour min I have a buddy at IBM and while it varies by group, his group does this : - $30/day for carrying it, whether it goes off or not - every page gets billed at time-and-a-half, minimum 30 minutes Anyone else want to share theirs? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

CentOS DS Transition Issue
by Camron W. Fox 26 Oct '09

26 Oct '09

Alle, We are looking to transition from OpenLDAP to CentOS DS. We currently using OpenLDAP V2.3.43-3 with both RHEL 5.4 and Solaris10 clients (auth/netgroup/automount). We restrict user login access to the RHEL and Solaris machines using netgroups. After configuring the CentOS DS, we noticed that while the RHEL restrictions using the /etc/pam.d/system-auth-ac and /etc/security/access.conf configurations worked correctly, the Solaris clients using +@netgroup in /etc/passwd, passwd_compat in /etc/nsswitch.conf and the appropriate /etc/pam.conf configs do not respect the restrictions. The client configurations have not changed, only the LDAP server. I know this is a long shot, but has anyone else come across this issue? Best Regards, Camron -- Camron W.

Packages in 5.4 older than 5.3 updates, and no 5.4 updates available?
by Stephen Harris 25 Oct '09

25 Oct '09

I've been checking the updates tree for 5.4 and notice that they're empty. I checked 4 or 5 different servers and got the same results. This is, in my experience, unusual; there's typically patches for the new release from day one. But it could be that the 5.4 DVD is up to date. So I checked one of my machines and what updates it would need against 5.3 vs those that it would need to update to 5.4 (I've not been keeping my patches up to date on this machine; I know... stupid me). My machine is 33 patches short when configuring yum to a 5.3 tree (base and updates; it'd take 202 patches to take it up to 5.4). Of those 33 patches, 19 are the same from the 5.4 DVD. Of the remaining 14 discrepencies 10 had newer versions on the 5.4 disk. So far, so good. But 4 packages concern me where it looks like the 5.4 DVD has older versions than the 5.3 updates: 5.3 update:dnsmasq.i386 2.45-1.1.el5_3 5.4 DVD:dnsmasq.i386 2.45-1.el5_2.1 5.3 update:fetchmail.i386 6.3.6-1.1.el5_3.1 5.4 DVD:fetchmail.i386 6.3.6-1.1.el5 5.3 update:gnutls.i386 1.4.1-3.el5_3.5 5.4 DVD:gnutls.i386 1.4.1-3.el5_2.1 5.3 update:nspr.i386 4.7.5-1.el5_4 5.4 DVD:nspr.i386 4.7.4-1.el5_3.1 (These are the 4 my machine flagged; there could be other packages of similar concern that haven't hit me yet) Is this merely a case that the 5.4 updates tree hasn't yet been pushed out and these changes should show up in the near future (when?), have I found a problem, or am I just plain and simple wrong? :-) -- rgds Stephen

Running SSH on a different port (with SELinux)
by Jorge Fábregas 25 Oct '09

25 Oct '09

Hello everyone, Now after the recent discussion on running SSH on a different port, I decided to start a new thread but with SELinux involved. Assuming that you have SELinux enabled, and that you changed the default port for SSHD, let say for 1234, when I restart SSHD I don't get any AVC denials. This is the output of: semanage -l port | grep ssh ssh_port_t tcp 22 I thought (based on previous SELinux readings) that in order to allow SSHD on a non-default port you needed to: semanage port -a -t ssh_port_t -p tcp 1234 That was the theory I read :) Now in practice it seems it is not implemented yet, or at least by the time RHEL5 came out. Does anyone knows? All the best, Jorge

kvm package difference - v36 via yum, v83 via DVD
by Brian Schueler 25 Oct '09

25 Oct '09

Hi! As far as I can see there is no kvm in the base repository but the older version 36 in CentOS-Extras. Version 83 that belongs to 5.4 is only found on the install DVD and CD-Set. So it's different when installing kvm later with yum which results in kvm-36 than choosing 'Virtualization' on DVD install that installs kvm-83. It's also a difference between installing from network and DVD, even when the same Kickstart file is used when kvm is selected. What is the reason of the base-repo/media difference? cheers, Brian.

I am a digest subscriber and the release announcement is contained in the very digest that contains your message. Therefore the answer is no. My question is: Given the knowledge I possessed, why would I have gone looking for such a document? Is every yum user expected to look for release notes before each and every time that they run yum update? On the other hand, because of yum's apparent inability to clean up after itself, I had previously adopted the practice of running yum clean all before and after every update, which I did do in this case. There is a fundamental problem with the software if an automated package manager like yum requires both prior external knowledge and manual intervention to effect a particular update. Surely if a yum update set contains package dependencies that are sensitive to installation order then there should be an automated means to insure that the requisite packages are installed in the proper order by the package manager itself and not depend on manual intervention. The current arrangement seems to lend itself to unfortunate results. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

Bootable 5.4 USB key...

Hi, I tried to convert my working 5.3 USB bootable key to 5.4 and I apparently cannot get syslinux to find/read its configuration file anymore... I followed the same process as before: mkfs.vfat -n BOOT /dev/sdg1 syslinux -s /dev/sdg1 cd /media/BOOT cp -rv /mnt/cdrom/isolinux syslinux mv syslinux/isolinux.cfg syslinux/syslinux.cfg rm -f syslinux/isolinux.bin vi syslinux/syslinux.cfg dd if=/usr/lib/syslinux/mbr.bin of=/dev/sdg I get: syslinux: cannot find kernel linux I tried to copy syslinux.cfg in /, but it still fails... Did anyone successfuly create a 5.4 key yet? Thx, JD

CentOS-5.4 Update?
by James B. Byrne 23 Oct '09

23 Oct '09

hdwr HPQ DC7700S ix86 Core Duo I have just updated this CentOS-5.3 box to 5.4. This process was not satisfactory. While the update packages all downloaded without problem the update process itself stalled at several points. By stalled I mean that at some point the entire process stopped for hours. The packages at which it stalled included evince, evolution, totem and vinfo. There may have been others but these I seem to recall. Restarting the update process required that the existing update be interrupted with a <ctrl>C and yum-complete-transaction run. It took five iterations to get through to completion and in the end I first installed all the remaining packages one at a time directly from the command line using yum install packagename and then ran yum-complete-transaction until all outstanding transactions were cleaned up. Now, while the system boots I have no gnome desktops for any of the users on this host. When root logs in all that is shown is a deep blue background and a wirefram outline of the Firefox web browser, a wire frame outline of an xterm window and an analogue clock. Left clicking on teh background displays a popup menu labeled "Tvm". The mouse and keyboard work and when one clicks on the wireframs then immediately fill with the application background, the CentOS welcome back for FireFox and a black on white scheme for xterm. All the windows have teal menu bars. Further, it seems that I cannot switch between windows. If I try to enter a command in the xterm window then what I type appears in this compose window for squirrelmail. I would like to get my previous customised desktops back, but first I would like to get the default to display. Are there any ideas on how to proceed?

Problems with BCM5709 network
by Toralf Lund 23 Oct '09

23 Oct '09

I've just installed CentOS 5.4 on an IBM server with a BCM5709 network adapter, and can't get networking to work. It looks like an appropriate driver (bnx2) is installed, lspci and the system log return sensible info on the unit, there are no specific error message anywhere, but I get "no link present" when I try to activate the device. In other words, I see essentially the same behaviour as when the network cable is missing, but I've tried several cables, connection points etc. and also get the appropriate indicator lamps etc. so I'm quite sure the connection is good. Does anyone have any idea what may be wrong? If not, have any of you lot got networking to work with a similar setup? Some extracts from the system log are included below...

upgrade to 5.4 openswan broke
by Myron Williams 23 Oct '09

23 Oct '09

Hi All, I upgraded from 5.3 to 5.4 today on a vpn gateway using openswan. After the upgrade the vpn stopped working. From what I could tell the new version of openswan uses NSS. I tried following the instructions in this thead https://bugzilla.redhat.com/show_bug.cgi?id=508107 without success. # certutil -N -d sql:/etc/ipsec.d certutil: function failed: security library: bad database. If I ran the command without the sql: like this # certutil -N -d sql:/etc/ipsec.d it would create the database files. I would then execute # modutil -fips true -dbdir /etc/ipsec.d followed by # /usr/sbin/ipsec newhostkey --configdir /etc/ipsec.d/nssdb --password password1 --output /etc/ipsec.d/host.secrets After replacing the hostkey in the file I tried to bring the connection up but the connection would not start and the following error message was in the log file. unable to locate my private key for RSA Signature sending notification AUTHENTICATION_FAILED I finally had to downgrade from openswan-2.6.21-5.el5 to openswan-2.6.14-1.el5 to get things to work. Am I missing something that is needed to make this work? Any help would be appreciated. Myron Williams

Persistent desktop icons ?
by Niki Kovacs 23 Oct '09

23 Oct '09

Hi, Is it possible to configure persistent desktop icons, e. g. shortcuts that users can't delete ? On most of my client desktops, I have some home-made shortcuts, like here for example : http://www.microlinux.fr/configurations.html The shortcut on the lower left corner of the screen launches the public library management system. Most of the users are quite computer-illiterate, and more often than not, they tend to erase these shortcuts (and then call me panic-stricken at 07:00 in the morning :oD). To configure the shortcuts themselves, I just edit a .desktop file by hand. I tried various combinations of chown and chmod, but to no avail. Even if there are minimum access rights, the thing can still be erased with a right click. Now I vaguely remember that a standard openSUSE install has something like persistent desktop shortcuts (for the SUSE help center or something like that), and I wonder: how do they do it ? Any suggestions ? Niki

5.4 docs
by Ron Loftin 22 Oct '09

22 Oct '09

First off, I'm glad that 5.4 is now available, and a big "Thank you" to the development team for all of their hard work. I have noticed that the docs for 5.4 appear to be accessible on the CentOS Web site, but some of them seem to have some issues. In the "Technical Notes", everything after the first page of Chapter 1 gives a 404 error. I've tried to send in a report with the contact form on the Web site, but so far this situation has not changed. Hopefully somebody on the team can look into this after a bit of rest and recuperation from their efforts on our behalf. -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?"
