Re: [CentOS] Backup PC or other solution
I wonder why nobody has yet mentioned rdiff-backup. It combines browsable directories with multiple versions - the version data is stored in a separate rdiff-backup-data subdirectory (one per backup task). One downside is that rdiff-backup causes a lot of network traffic. For that reason I currently use rsync to copy over network, and then I use rdiff-backup locally to create a repository with multiple versions. Another system that we use is rdiffweb. It uses rdiff-backup over network and adds a web interface for clients to browse and restore files or directories. I did not personally set it up, but it seems to work fine. - Jussi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The one I tried was made with perl, temper-poll is python. I tried the python scripts too, but stumbled on problems there, too.

Ok, I found it, and it is *so* obvious. Still it took me hours to find it.
I had this in my config for the "rx" instance of sendmail.
FEATURE(`mailertable', `hash /etc/mail/mailertable.db')
And my mailertable contained static routing for all domains that are
local to our primary mail server. Example:
greenspot.fiesmtp:[mail.greenspot.fi]
So sendmail was only following orders. Solution: comment out the
mailertable line from the sendmail config.
Thanks to everyone, and especially to Alexander for reading so carefully
my emails and giving the breakthrough tip. I love you!

Looks like you are right - and that's a breakthrough! I checked on the
primary mail server using simply
tcpdump host 83.143.217.179
and I noticed connections to port 10024.
I should have used tcpdump earlier in this process - but better late
than never.
Now I just have to fix the sendmail ("rx" instance) config so that it
really sends the email to localhost (where amavis is listening), instead
of trying to send directly to the final destination. So far no luck. A
similar setup works ok on the primary mail server, so I don't know why
this one does not work.

Yes. In a dual sendmail setup there are two instances of sendmail. The
receiving one ("rx") dumps all email to amavis (TCP 10024), and then
amavis hauls everything back again to the other instance ("tx") (using
TCP 10025), which sends it away over net or piles it up in local mailboxes.
My conf for the "rx" instance is probably not important, as the "rx"
instance does not actually contact anything outside localhost. The
submit conf is for mail submission, so it is probably not used here.

That is why I am baffled. :-/ I could use a way to see what port sendmail is actually using to make the contact. My assumption is that when the log entry (see my orig post) says "mailer=esmtp,", it implies port 25 - but then it really does not make sense that the connection is refused.

Some more info. Below is a more complete telnet session from backup mail server (mx2.greenspot.fi) to primary mail server (mail.greenspot.fi). It only proves that sending mail works fine from command-line. But my sendmail setup cannot do the same. I wrote that MAILER-DAEMON can get mail through. I am not actually sure about that.

I only wrote that I know vim *better* than sed, awk or perl. Obviously
there is a lot about vim that I don't know.

Ok, that helped me along. For some reason the motions (like 1G0 for
beginning of file, or G$ for last char in file) work, when the script is
called from command-line with -s flag (vim -s myscript myfile). But they
don't work when the script is called from inside vim (:source myscript).
I wonder why.
However, this script does more or less what I want - transforms a
tab-text file to a comma-separated (CVS) file:
:% s/\t/","/g
:% s/\r\n/\r/g
:% s/\n/"),\r("/g
1G0I("^[
Gdd
G$xa;^[
:w
Comments to lines:
1) replace tabs
2) make line endings regular
3) insert quotes and brackets to end & beginning fo each line
4) handle the beginning of file
5) remove the last line (created by this script)
(the command G works, but it rings the bell for some reason)
6) handle the end of file
7) write file
So this was my first-ever vim script. So far I am not convinced about
vim scripting (ok, I was warned, too)... Test cycle is slow (modify
script, quit the realfile, open realfile again with vim -s script).
Verbal error messages would be useful. There is supposed to be
"integrated debugger". I would like to know more.

[CentOS] Vim scripting - cursor motion
I am working on my first vim script. The script is supposed to do some find/replace on a file, then save the file with a new name and quit vim. I will save the script in a file and then call it from a bash script like this: vim path-to-the-file -s path-to-my-script Maybe I have not found the right resources. I can find/replace with expressions that are similar to those I use manually, for example: :% s/\t/","/g Then I should add something to the beginning of file (line 1, char 1).

Re: [CentOS] OT: Why VM?
It has been a long thread, but one point that has been mentioned only in passing (VMWares "top 5 reasons") is cutting the electricity consumption. Maybe this is obvious. I recently consolidated 8 hardware servers to a single 1U Dell, which runs KVM virtualization. The power bill was cut to a fraction! Do the same on a bigger scale, and it will be a significant saving. Also it reflects on cooling costs.

I think you are inadvertently confusing the issue. ftpd is mentioned in
this file (see below), but still vsftpd is used:
[root@mx2 logrotate.d]# cat vsftpd.log
/var/log/vsftpd.log {
# ftpd doesn't handle SIGHUP properly

}
/var/log/xferlog {
# ftpd doesn't handle SIGHUP properly

As for me, vsftpd is logging to xferlog, and it is rotated normally
(CentOS 5.6) with the following settings in vsftpd.conf:
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
xferlog_enable=YES
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file

There are some googlable ways to feed a list of filenames to vim, but I stumble on weird results. With my filelist, I try to do cat list | xargs vim ...to edit the files listed in the file "list". Here's what happens: [root@lasso2 tempdir]# ls -l total 8 -rw-r--r-- 1 root root 0 May 17 18:28 a -rw-r--r-- 1 root root 0 May 17 18:28 b -rw-r--r-- 1 root root 3 May 17 18:31 c -rw-r--r-- 1 root root 12 May 17 18:43 list [root@lasso2 tempdir]# cat list ./a ./b ./c [root@lasso2 tempdir]# cat list | xargs vim 3 files to edit Vim: Warning: Input is not from a terminal Ok, so far, so good. And after this, the file a opens, as expected. However, the contents show as all uppercase. And everything I write is uppercase too. I can move to the next file (:n) even though the command shows as uppercase (:N). I cannot quit vim, however. When I do ":q", I get blank screen, and I have to close the terminal window. If I do instead cat list | xargs less ...it works as expected. And with cat list | xargs vi ...(in a fresh terminal window), the editing goes just perfect, but when I quit vi, the terminal will not show the commands I write, and the display gets garbled (no newlines etc.).

[CentOS] Identifying physical disks
I am sure this is really simple. I have a setup of 2 disks (sda, sdb) which are outwardly identical, and are mirrors of each other. Together they form 3 raid1 devices. Both disks can boot. Now sda has bad sectors, and I should replace it. But which one of the physical disks is sda?? The machine boots fine from either one of the disks, (and the booting disk of course is always called sda). In the messages log I see entries like this: Apr 29 02:21:07 a134-224 kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) By noticing which SATA link (ata1, ata2) is up and which is down, I can find out which physical disk is connected to ata1 and which to ata2. If both disks are connected, will the hd in ata1 become sda, and the hd in ata2 become sdb?? - Jussi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Install CentOS as KVM guest
I understand you so well, I have been so frustrated too with virt-install. Virt-manager is probably an easier way to install, but text-based virt-install is very cranky (my experience). Maybe the devs concentrate on the GUI side. Hope not. Anyway, to know what is wrong, more info would be needed... Especially, at what point does the installation stall. Here is one of my install commands that worked: virt-install --name mail \ --os-variant rhel5.4 --ram 1024 \ --vcpus 2 --accelerate \ --nographics -v \ --location /mnt/centos56/ --network bridge:br0 \ --disk path=/kvmail/mail.img,size=290 \ --extra-args "console=ttyS0"; So I boot the installer from a mounted DVD, then in the dialog I say "http install", and give it my local http "repo". No other bridge is necessary - I think it would only make things messy. In the installer let it configure interface with dhcp, if applicable, or give it a free ip. In giving the http repo remember the slash after the subdirectory, for example (I noticed it is necessary) address: 12.34.56.78 directory: centos/4.9/os/i386/ This would be http://12.34.56.78/pub/mirrors/centos.org/4.9/os/i386/ Check in your browser that the path works. The stage2 image should appear in seconds from a local repo! Once I did a net install with --location http://ftp.funet.fi/pub/mirrors/centos.org/4.9/os/i386/ But on another try it did not seem to work anymore. Not sure about that. Anyway the mounted ISO works every time. And a local repo is very fast. - Jussi On 26.4.2011 23.57, Emmanuel Noobadmin wrote: > Unfortunately, things still don't work. > > > It's just ridiculous that the installer under KVM does not detect the > cdrom drive it was booted from.

Re: [CentOS] KVM, virsh attach-disk error
Now I could attach a disk to the KVM guest, using a virtio driver: > [root@113 info]# virsh attach-disk test1 /dev/sdd1 vdb > --driver virtio --mode shareable > Disk attached successfully I have not seen any mention anywhere about using virtio drivers like this. Here /dev/sdd is a separate disk, not used directly by either kvm host or guests. Before the operation, sdd1 was created with fdisk as a Linux partition. After the operation, I did mkfs.ext3 on the guest and then mounted the new filesystem. But the Bonnie benchmark results for the KVM guest are not promising - they are about the same for the new external partition and for the guest's native filesystem. Reads are in fact much slower on the external partition (27500 vs. 7 k/s). (CPU load 4 vs. 12 %.) Writes are faster (121000 vs 98000 k/s). (CPU load 12 vs. 10 %.) If these results are weighed with the cpu load, the differences even out. Maybe the evennes is because the external partition is used with virtio drivers, same as the guest's native disk image. So why bother? I think I will give each guest one disk image to run on, and that's it. Unless I find a better way to attach partitions to guests. - Jussi -- Jussi Hirvi * Green Spot Suvilahdenkatu 1 B 78 * 00500 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hi...@greenspot.fi * http://www.greenspot.fi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I do text-based installations with virt-install, and follow this procedure: - if you are going to do several VM installations, then before you install, copy the directories you need (for example centos/5.6/os/x86_64/) from a CentOS mirror to /var/www/html on the host - start httpd on the host, check in the browser that you can access the CentOS files - from a CentOS mirror, download any bootable iso (netinstall cd, or installer cd #1 do fine) to the host - mount the iso using "mount -o loop" - do virt-install - for "location", use the mounted iso - do a "http" installation using your local http "repo" (refer to the host with its public ip number; 10.0.2.2 did not work for me) - Jussi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] KVM, virsh attach-disk error
I try to add a fresh, unformatted disk partition to a KVM guest.

It is. On the host I write: virsh attach-disk test1 /dev/sdb1 sda --driver tap --mode shareable - test1 is my guest domain - /dev/sdb1 is the name of the unformatted partition on the host - sda is what it is supposed to be called on the guest (the name is unused on the guest) - the example in RHEL Virtualization guide says "--mode readonly". This does not sound right for a hard disk; hence I try "--mode shareable"; the error (see below) however is the same, whichever I use Now, the command above produces this error.
