I've used both 'remove' and 'history undo' and had better success (system not having something important removed) with the latter. .. and so I was wondering whether it's advised to use this form rather than yum remove, and to find out why 'remove' is less successful (or if it's just me!). Another example I had recently was when I installed Networkmanager-openswan and then after installing realised that it didn't support L2TP/IPSec VPNs so I uninstalled it, again with 'yum remove'. It removed the WiFi applet from the Gnome panel, which wasn't what I was expecting. I had to reinstall networkmanager to get it back. It just seems I should probably be more cautious of inspecting proposed system changes when doing 'yum remove' but just wanted to make sure that I wasn't doing something wrong.

[CentOS] OT: Rewrite part of a message with rsyslog
Hi all, Sorry for the off-topic, but I have not found how to do this. I have installed a centos6 server to act as a syslog receiver. I need to rewrite all messages that comes from one server. For example a part of the message is: "27April2012 10:33:44 172.1.2.2 data >". Sometimes between 27April2012 and 10:33:44 comes with one white space, sometimes with two, etc. I need to normalize this log to use only one white space between all fileds until ">" character. Somebody knows how can I do this?? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] UC OT: Rewrite part of a message with rsyslog
Use AWK:
{ print $1, $2, $3, $4, substr($0, index( $0, ">") }
Explanation:
AWK will split the line up on white space, so printing $1, $2, $3, $4
will give you
"27April2012 10:33:44 172.1.2.2 data" single spaced. The substr
expression will
return the rest of the input line ($0) unchanged from the right arrow.

Re: [CentOS] UC UC OT: Rewrite part of a message with rsyslog
You need to set up the AWK script as part of a pipeline:
... | awk '{ print $1, $2, $3, $4, substr($0, index( $0, ">")) }' | ...
By the way, if you are not familiar with AWK:
1) The outer brackets are curly brackets
2) The inner two sets are parenthesis
3) There should be no space between "substr" and the left parenthesis
or between "index" and its parenthesis.
man awk will give you lots of information!

[CentOS] fail2ban logrotate failure
I got the fail2ban from epel. There were a number of issues relating to using a log file... logwatch was looking for both fail2ban and fail2ban.log logrotate file fail2ban added looked for fail2ban.log and then reset itself to syslog fail2ban itself went to syslog, over riding its fail2ban.log. took a while, but I use /var/log/fail2ban now, that finally worked through logrotates and logwatch. Problem with centos variant of fail2ban: logrotate causes all 'ban' actions to stop happening. I am pretty sure it stops reading the logs but still functions. Unban actions still keep showing up in the log, but the 'ban' actions just stop. Program is running, but no longer working. Long searches online show a million others with the same issue. Only way to prevent it seems to be to add a reload or restart in the syslog file. This is undesired due to losing all banned ips listed. It happens as part of the logrotate. The logrotate file I have changed a few times and recently tried this postrotate /usr/bin/fail2ban-client set logtarget /var/log/fail2ban 1>/dev/null || true endscript setting the logtarget, which the original called for changing it to syslog and 2>dev/null || true so what would you do? I imagine when logrotate happens and syslog restarts something is causing fail2ban to stop working properly, but still timing 'unbans'. This is apparently a bug/problem for almost everyone of all distros. Other than just uninstalling, the only way to make it work would be a restart around 4 every morning, making any long term bans useless. My last thought is to just throw the /var/log/fail2ban to be rotated by syslog like maillog and the others..and not doing anything special. Maybe it would just work. I write here because I know there are hundreds of you and someone must have figured out how to make fail2ban work for more than 24 hours without a restart ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yum is great for adding packages. I never use it to remove packages. I might use it to give me a list of packages to remove and then modify that list and then do: rpm -e $(cat list.txt) If I do use yum to remove a package group, then I would install "X Window System", "Desktop" and any other things that might be impacted. Yum always has, IMHO, removed too many things when using it to uninstall. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

So the real problem is that you don't understand the directionality of dependencies. "yum install packagename" installs packagename + anything that packagename requires. "yum remove packagename" removes packagename + anything that requires packagename. The set of packages required by packagename and the set of packages that require packagename are two entirely different things. For example, let's have three packages A, B, and C where B requires A and C requires B: A<-B<-C "yum install C" will install all three packages. "yum remove C" would remove only C. "yum remove B" would remove B and C.

Yes, I thought "yum remove packagename" would remove the packagename plus any dependencies that were INSTALLED by the "yum install packagename" action. That is, I expected it to NOT remove dependency packages that were already present when "yum install packagename" was performed. So a misunderstanding on my part. I just need to be really careful about the remove command in future. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I did two, one for boot, the second was the OS boot- add a raid partition, did it for each drive, then make a raid device and select all both drives, /boot for mount point OS- added a raid partition for each drive, then when you make the raid device select physical volume as the file system type and both raid partitions you made for the OS. then you hit create again and select volume group, select the raid device you want to play with. you add mount points, these are your logical volumes... /swap / /var etc etc etc you cannot clone like you did in centos 5, so you must make the raid devices on each drivea lot of deselecting and repetition to add a slave, you need to go through the motions, then edit your physical volume raid deviceit will then allow you to make one a spare...until then the spare selection is greyed out... hope this helps. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it for swap) md2 All remaining space (use it for /) 2) Created two physical LVMs, one on md0, the other on md1. 3) ? This is were I am confused, do I create two LVM volume groups? I was thinking that my primary LVM can be ~1TB and that my other LVM which I snapshot to can also be ~1TB. Anyways, I am very green on this topic as I usually do hardware raids but I don't have that option.

Why on *earth* would you think I would suggest not testing? Rather, if it were up to me, I'd run them in parallel for a year (so as to include year-end closing). Among the reasons I suggest it is to a) get rid of the tested spaghetti code (and yes, I've maintained crap like that, though not in a lot of years, thankfully); b) structure it using control structures that all modern language have (as opposed to, say, PERFORM 1500-DUMMY-PARAGRAPH THROUGH 1500-DUMMY-PARAGRAPH-EXIT VARYING I FROM 1 WHILE I < 200, which yes, I left a lot of behind me, faking for/next loops that way), and, finally, c) it's getting harder and harder to find anyone who knows COBOL, since it's not a required course, and hasn't been for a lot of years mark mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I played with it once years ago; it seemed to work Ok. Sadly, COBOL is not COBOL and ISAM is not ISAM, so code portability isn't likely and the Open COBOL application possibly won't be able to access the files from an RM or Acu COBOL application [some things never change]. So you'd at least have to export / import any data between COBOL compilers.

I have only this suspicion. It may be that yum history undo only rolls back the changes actually made by the previous yum update/install since it 'knows' that the system environment has not changed in the interim. Whereas yum history remove, since it has to cherry-pick packages from a possibly changed environment, instead removes rpm dependencies based on the package specs of the items directly added by the original yum command, whether these were installed in that transaction or not.

Wow, I think I did it. Re read your reply a few times and yea, nice man. Thanks much for the reply.

[CentOS] imagemagick convert/display eps file no decode delegate
I am finding on all my CentOS 5.8 systems (all fully updated but a variety of package mixes) that the display or convert commands from ImageMagick are unable to handle eps files. I get error output as follows, curious if anyone else sees this $ convert rna.eps rna.epi convert rna.eps rna.epi Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 convert: no decode delegate for this image format `rna.eps'. convert: Postscript delegate failed `rna.eps'. convert: missing an image filename `rna.epi'.
