Hi The reason for Ubuntu in the laptop is simply because CentOS didn't work very well. I followed the wiki about XPS M1530[1] and everything almost work. At the office one of the developers uses a Dell Precision laptop with RHEL 5.3 (it came from Dell with RHEL) and works really fine. So, I image that some laptops are more CentOS/RHEL-friendly than others. Now I'm used to use sudo. It is a great tool. I use it everywhere. And everything I do appears in the logwatch. Regards mg.

ftp issue in Centos 5.3
by Dave Stevens 30 Sep '09

30 Sep '09

I manage a small server that I back up weekly. I do this by making a tarball of relevant files then transferring it over the local subnet to my station (Fedora 11), whereupon I burn it to DVD. There is no optical burner on the server. The tarball amounts to a bit under 5 gigs. Recently I've started getting an error telling me to try PASV or PORT first. I use the gFTP client on my machine and as far as I know there is no option in this program to use either option either locally or remotely (on the server.) Any ideas on this one? Dave -- When addiction becomes commonplace in a society, people become addicted not only to alcohol and drugs, but to a thousand other destructive pursuits: money, power, dysfunctional relationships, or video games. A social perspective on addiction does not deny individual differences in vulnerability to addiction, but it removes them from the foreground of attention, because social determinants are more powerful.

-----Original Message----- From: Brian Mathis The difference is that CentOS is a general-purpose OS that can be used for many things, and has a much bigger installed base. That makes it more of a target and would likely be included in scanning tools. A custom OS running on a PBX might also have vulnerabilities, but it's also probably not a big target because of the diversity of systems out there and relative limited utility one would have if such a system were compromised. That you tend to tend to think of it as an "appliance" running the phone system does not change the fact that it's actually a full-blown server OS with the same issues as other servers. _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

cups-lpd job settings
by janezkosmr 30 Sep '09

30 Sep '09

Does someone know, how to configure cups lpd job options. My xinet.d config looks like this: # default: off # description: Allow applications using the legacy lpd protocol to communicate w ith CUPS service printer { disable = no socket_type = stream protocol = tcp wait = no user = lp server = /usr/lib/cups/daemon/cups-lpd server_args = -o job-sheets=none,none -o cpi=12 } The problem is, that it cups ignores the second option under server_args. I checked the documentation and googled quite a lot, but I couldn't find an example with more then one option. BR Janez

Scan to email
by Joseph L. Casale 29 Sep '09

29 Sep '09

Anyone done this w/ Linux before? Not having ever used this functionality, I can only speculate but I have been asked to setup an MFP such that when you scan to email, it hits a postfix instance which rewrites the email (so it can be typed short) and sends it on to our email-fax service. It seemed simple, so long as I get an MFP that supports emailing from its console as all the cheap mfps's I know of require some lame app that usually only runs on windows. It all seems simple enough, pending I get the appropriate mfp? Anyone done this with an Ethernet based unit that can share an opinion? The postfix rewriting part seems simple enough! Thanks! jlc

Removing xorg stuff
by Bob Hoffman 29 Sep '09

29 Sep '09

Starting to clean out my server. I use command line only. Even though I tried not to install the gnome and x, a lot of stuff did install anyway. In testing the removal process I find I cannot use yum remove due to losing to many programs due to dependency. Trying to remove via rpm -e is nigh impossible as it appears to be an unknown chain of dependencies separate from the ones using yum that block any way of deleting it. I am thinking to do a rpm -e and then trying to take out all the dependent ones.. However..I am not sure about taking out X since so many items were installed with the system and maybe some are needed? It is obvious that I need to do one or a few files at a time since I can find no way to take out the whole xorg package as of yet. My big fear....is X needed in some way by my server in ways I do not know? I use it as a webserver and shell in with no graphic interface stuff except those like system-level-security and such... No many x installed items deal with lvm and such...scary

Antispam with Postfix
by Joseph L. Casale 29 Sep '09

29 Sep '09

I am mulling over the thought of replacing my current solution, it works very well except for the following two issues: 1. LDAP recip verification for only one server, this gateway services multiple domains who's directories are independent. I need to be able to verify the various domains off of independent servers. 2. I use backup mx's, my current solution probably could work in this scenario but the support mechanism behind it is *very* weak and I can't get a perfect setup working. Spam hits the primary for a domain, gets blocked and then tries my secondary which sometimes accepts it, after which the primary always accepts from the secondary. What are some setups that use Postfix which you guys are having very good success with that isn't a burden to administer. The last thing I want to do is replace my one single app with many:) Thanks for any ideas! jlc

Slow printing to HP jetdirect from cups
by Bowie Bailey 29 Sep '09

29 Sep '09

I've googled for this and poked around linuxprinting.org, but couldn't find anything helpful. I have a CentOS 5 server with an HP LaserJet 4 attached via JetDirect with the hplip driver. The problem is that when I have multiple print jobs in the queue, there is a delay of about 15 seconds between each job. This gets very annoying when there are 10-15 one-page jobs in the queue. "lpstat -t" shows me errors like this: recoverable: Network host 'seashell' is busy; will retry in 15 seconds... This worked fine previously with the same setup on an old RedHat release (Either RH7 or RH9, I don't remember which). The problem appeared after I rebuilt the server with CentOS 5. Any ideas would be appreciated. -- Bowie

I'll look into that though. I'd like to know the point with it. What happens when you mount 2 otherwise identical disks/filesystems? As might happen if you take a disk from a default install and mount it into another similar system? I haven't tried with a recent fedora version, but I'd guess it still won't work if you have the default LVM volume id from an install - they've gotten this wrong with every label/id approach so far. Even people who are 'no-tech' types as far as Linux goes may want to swap drives around and copy some old data or at least look at the contents before reusing a drive. -- Les Mikesell lesmikesell(a)gmail.com

Server software has been fairly 'feature-complete' for a decade or so and there's not a lot of point in using a rapidly changing distribution to run it. If you did use Ubuntu, you'd want the LTS (long term support) version. On the other hand, Linux desktop software still has a ways to go and there are more reasons to accept the new bugs that come along with new features and the need to upgrade more often. RHEL's decision to update the versions of Firefox and OpenOffice in a minor release helped, but it still feels very old as a desktop. -- Les Mikesell lesmikesell(a)gmail.com

I understand the goal Fedora project to test the latest software available. In this way, Fedora isn't for everyone. At least is not for your main system, but if you have a spare machine to install and play with it, it's probably a good idea. In my case, the rpmfusion NVIDIA driver didn't like my card, a Quadro NVS280. I there are too many updates, and sometimes they crash something. I remember while using Fedora 10, after disappointment with F9, after an update, the sound stopped to work. I didn't like the idea of Thunderbird beta in F 12. Also, the external drives are mounted using the uuid(?) name, so instead of /media/disk, appears something like /media/88299233ddd22, which breaks my backup/recover script. And a few other thinks. My general option was that the experience wasn't good, or put in another way, Ubuntu works better. None of this is critical, but it is annoying. For me, a good distribuition would be something seating between Fedora and CentOS. In the last months I started thinking that Ubuntu feel this gap. I still believe that CentOS is best option for servers and technical workstations, but not for my laptop, a Dell XPS M1530. Regards mg.

Software Raids Questions (I have only ever used hardware?)
by James Bensley 28 Sep '09

28 Sep '09

Hey List; I have no experience with software RAIDs; at work we only use hardware RAIDs and I'm looking to implement, probably a RAID 5 set up at home for a media server however I have a few questions; I have three 1TB drives in various places; one is inside a USB caddy, one is inside my PC and in is inside my existing media centre. Is it possible to add these three drives to another one to give me 4TBs of space in a RAID setup without having to wipe the drives as in my experience which is only with hardware RAIDs, I have normally formatted all the disks before creating the RAID? The thing is, if that is the case I will need to transfer 3TB of stuff somewhere (I have an idea where, if this were the case), make the RAID then transfer it all back but I really don't want to do that as I'm sure you can imagine. Also, if the above where possible; in the future could I then keep adding more drives and expanding the RAID? Note: Obviously I know for this to be a RAID 5 I would need extra drives but the RAID level is undecided, but provisionally I think it will be RAID 5. On a side note, I cobbled together my new media centre running Ubuntu but I might move it back to CentOS, it was originally CentOS and that is my favoured distro, but I would rather not now it is running Ubuntu happily I'm just wondering, is this all achievable in Ubuntu? Granted people on the CentOS mailing list might not know that, but if anyone knows that it is all achievable in CentOS then I would move back? Thanks for reading.

IP aliases of CentOS Guests not accessible running 2.6.18-164.el5xen
by Devraj Mukherjee 28 Sep '09

28 Sep '09

Hi all, First of all I am posting this on two lists for a reason, because the issue being reported by me could be because of a change delivered by a Kernel update or due to Xen. I have recently managed to update all Xen Guest domains running CentOS 5.3 to the latest bunch of updates + Kernel. My Xen host also runs the same CentOS 5.3 updated to all recent packages. The Guest images in concern had IP aliases assigned to them. Everything worked until I ran the updates and restarted. Since I have restarted the aliased IP addresses are no longer accessible from the outside world, they can still be accessed from all machines (guest virtual machines) in the subnet (ping, services like http). I have removed all firewall rules to test if that would have effected it without any change (any the fact that I can access them within the subnet proves its not the firewall). Is there anything special I have to do to enable aliasing? May be this is a Xen issue? I am suspecting the Xen host, but not sure how to go about proving this. Any information would be greatly appreciated. My Guests do run fail2ban (delivered via atrpms) and iptables (allowing only HTTP, HTTPS and SSH) connections. PS for obvious reasons I am not posting IP addresses and routes etc first up, I can make that information available if required. -- "The secret impresses no-one, the trick you use it for is everything" - Alfred Borden (The Prestiege)

Using yum with CentOS-2 mirrors
by Matt Arnilo S. Baluyos (Mailing Lists) 28 Sep '09

28 Sep '09

Hi all, I was having yum errors while updating our CentOS-2 box. Further reading lead me to a readme file on the mirrors (http://mirror.centos.org/centos-2/readme.txt) and it gave me the new URL to use for CentOS-2 mirrors. I have edited /etc/yum.conf with the new URLs but I'm still having issues with yum giving me "ValueError: unpack list of wrong size" errors. Has anyone been able to update their yum configuration to be still able to use yum? How were you able to configure it? I understand that CentOS-2 has now reached its EOL but we have a legacy application that won't run on newer distros. -- Stand before it and there is no beginning. Follow it and there is no end.

External Backup Systems?
by M. Hamzah Khan 28 Sep '09

28 Sep '09

Hey everyone, My home server just had a disk failure a few weeks ago and like a lot of people I haven't ever really made backups on a regular basis. So I was looking into backup solutions which will save me from this situation again. Now I have Bacula setup, and backing up my files onto my home server. Although this works great, I have one issue: The disk in my server was the one that actually failed, and so, even with RAID1, could fail again. So to get around this I wanted to backup to external media aswell. I don't really think external hard drives are that great considering they are just as reliable as internal hard drives which would be pointless as RAID1 should be reliable enough in that case. Backing up to DVDs are quite unreliable too, a simple scratch could render the backup useless. Also it would require quite a lot of DVDs to backup my data (at least 500GB!). The only other option I could think of is to use tapes, but this option can be quite pricy for a home user. So I was wondering what you guys use for external backups for a home system containing at least 500GB worth of important data? Regards Hamzah -- M.

SUMMARY : multipath using defaults rather than multipath.conf contents for some devices (?) - why ?
by McCulloch, Alan 27 Sep '09

27 Sep '09

The reason for the behaviour observed below turned out to be that the device entry in /etc/multipath.conf was inadvertently appended *after* the devices section , rather than inside it - so that we had #devices { # device { # blah blah # } (file has a bunch of defaults commented out) # etc #} # # device { our settings } *rather than* devices { device { our settings } } Also - looking more closely at our multipath.conf.defaults, there is an entry for a product pattern HSV2.* That would explain why the multipath settings for the HSV200 looked different to the HSV400 - the HSV200 was picking up a different set of defaults. However still not exactly what we had specified. (sort of like CSS behaviour....."cascading multipath.conf defaults" ! :-) ) You also possibly need to pay attention to the basic whitespace formatting of this file - for example I had noticed the above early on and rebooted with it "fixed" , only to find that this meant the system came up unable to even recognise the ext3 filesystem, complaining about bad superblock etc etc. After recovering from that ( see below) I went back ( a week later) and a) made sure that the whitespace - tabs etc - looked like the other commented out defaults and b) added in a second device entry (from the defaults section - not a device we even have) , just in case there was some bug relating to having only one device entry in the "devices" section. Whether because of those or some other change, the system now comes up fine, and with multipath -ll now reporting the correct settings for the HSV400. So issue resolved finally. Touch wood. Here is a useful tip (not news to gurus but was to me ) : when things turn to custard on reboot and everything including the root filesystem is mounted readonly - so you can't even restore multipath.conf to the backup you made before rebooting - you can mount -n -o remount / to remount / as writeable - then you can cd /etc cp multipath.conf.bu1 multipath.conf and breathe a big sigh of relief ! If there are any multipath developers reading this - it could be handy if multipath could log some diagnostic info about how it parses the conf file , and exactly what entry it ends up using , which would then appear in /var/log/messages and /var/log/dmesg, since it seems relatively easy to end up matching a device spec you didn't expect, and the effects on performance are subtle so easy to overlook this. Cheers AMcC ------------------------ original post ------------------------ hi all We have a rh linux server connected to two HP SAN controllers, one an HSV200 (on the way out), the other an HSV400 (on the way in). (Via a Qlogic HBA). /etc/multipath.conf contains this : device { vendor "(COMPAQ|HP)" product "HSV1[01]1|HSV2[01]0|HSV300|HSV4[05]0" getuid_callout "/sbin/scsi_id -g -u -s /block/%n" prio_callout "/sbin/mpath_prio_alua /dev/%n" hardware_handler "0" path_selector "round-robin 0" path_grouping_policy group_by_prio failback immediate rr_weight uniform no_path_retry 18 rr_min_io 100 path_checker tur } - but our actual multipathing as shown by multipath -ll , and multipath -ll -v 3 looks as though for the HSV400 it is using the defaults rather than these settings. The defaults are #defaults { # udev_dir /dev # polling_interval 10 # selector "round-robin 0" # path_grouping_policy multibus # getuid_callout "/sbin/scsi_id -g -u -s /block/%n" # prio_callout /bin/true # path_checker readsector0 # rr_min_io 100 # rr_weight priorities # failback immediate # no_path_retry fail # user_friendly_name yes and multipath -ll reports : . .

[snip other HSV200 paths - all similar] multipath -ll -v 3 includes explicit statements that defaults are being used for the HSV400 (long output snipped...) sdaa: path checker = readsector0 (config file default) versus sda: path checker = tur (controller setting) sdx: getprio = NULL (internal default) versus sdd: getprio = /sbin/mpath_prio_alua %n (controller setting) - furthermore we see in the log file messages from both readsector0 *and* tur rather than just tur if the correct settings were used , which also backs that up. My questions are basically - why is it happening , and how to fix it ? The vendor and product regexps definitely do match both "HSP" and both "HSV200" and "HSV400" respectively so it doesn't seem that fiddling with the patterns will work , and I'm sure this config has been tested. Its not due to this server having to deal with two controllers - we have a second server that only mounts from the HSV400, and its multipath settings appear to be entirely the defaults, and not what we have set. (And conversely, its not due to the conf file not being read at all - since the server with two controllers is using the correct config for one of them , but not the other.) thanks for any tips and I will summarise.

mounting images created using dd that contain two partitions
by Devraj Mukherjee 27 Sep '09

27 Sep '09

Hi all, I am trying to mount images that I previously created with dd and the images have two partitions (swap and LVM). I use these images to house data for my Xen Guests. For some reason (possibly Kernel conflicts for paravirtualized domains) I am unable to boot my Guest images. Failing which I would like to mount the disk images and atleast get my data out of them. dd -o loop server.img /media/diskimage asks me to provide a file system. How can I mount these images? I have been Googling around for this and have failed to find and answer, can someone please point me in the right direction.
