how to clear out /var/cache?
by Fred 04 Jan '22

04 Jan '22

Is it safe to just remove files from /var/cache on a running system, or is there a correct procedure for doing that? Mine has hit over 3 gigs, making it one of the larger directories in /, which is running low on space. I've hit all the low-hanging fruit I can find and now I come to things like /var/cache, and I don't know what to do about such. Thanks in advance! Fred

Re: [CentOS] how to clear out /var/cache?
by Fred 31 Dec '21

Skylar: that's more or less what I've been doing, looking for huge things in /. Kenneth: the latest version of kdirstat appears to now be named qdirstat, no kde bits required. it is certainly a handy way to quickly find the disk space sinks. Thanks for the pointer. but I still don't know the proper way to clear out a lot of this stuff. I certainly don't want to hose my system. It is C7, up to date, and it has been running for at least five years with partitions as they are set now: / is 50 gigs. had a popup message this morning telling me that / was nearly full. found it with 2 gigs free. sounds as if something has been slowly eating away at the space. I could use gparted to rearrange things, making / bigger, but as it has been going for five years, it strikes me that it more likely needs a lot of garbage collection to be done. I've manually cleaned up some detritus, it now reports 3.7G free which should hold me for a little while. So, can anyone advise me on what is and what is not safe to whack/delete from the root partition? Thanks!

Delete local user/group but not LDAP one
by Felix Natter 30 Dec '21

30 Dec '21

Dear fellow linux users, I have a computer with a local user X that shadows an LDAP user of the same name (and group). I know I can use: userdel X groupdel X but how do I make sure that the LDAP is not changed, and only the local user/group is deleted? This is very critical. Many Thanks and Best Regards, -- Felix Natter

issue with virt-install and CS9 boot iso
by Leon Fauster 29 Dec '21

29 Dec '21

I wanted quickly spin up a CS9 system with an virt-install command line that in the past worked with fedora34 and C8 but I am getting following error: ERROR Error validating install location: Could not find an installable distribution at URL '{trimmed path}CentOS-Stream-9-20211222.0-x86_64-boot.iso' Some search engines found some sites that are giving examples to pass locations of kernel and initrd. Are the iso files "wrongly" created or are such parameters required now? Host: CS8 virt-install -n c9x86-parttest -r 3072 --disk path=parttest.img,size=18,format=qcow2 -l CentOS-Stream-9-20211222.0-x86_64-boot.iso --os-variant rhel9.0 --noautoconsole -x "inst.ks=https://example/parttest.cfg" -- Leon

Roundcubemail
by TE Dukes 28 Dec '21

28 Dec '21

Hello, Just upgraded from CentOS 7 to CentOS 8 Stream and there is no rpm for roundcubemail. Could I get the SRPM for CentOS 7 and re-do it for CentOS 8? I really hate installing a non-RPM package. If not a good idea, what is available for webmail in CentOS 8 Stream? TIA

CentOS 7: gdm/Xorg logs flooding, disk full
by wwp 22 Dec '21

22 Dec '21

Hello there, yesterday my main hdd, hosting a CentOS 7 system, went full.. I could figure out what happened: /var/log/Xorg.0.log and /var/log/gdm/:0.log files were both enormous (several GB each), flooded with messages like that: (Xorg's log excerpts) Auth name: MIT-MAGIC-COOKIE-1 ID: 441 [ 18.958] AUDIT: Wed Dec 22 16:18:19 2021: 3999: client 1 disconnected [ 18.960] AUDIT: Wed Dec 22 16:18:19 2021: 3999: client 1 connected from local host ( uid=0 gid=0 pid=4552 ) (gdm's log excerpts) Auth name: MIT-MAGIC-COOKIE-1 ID: 441 AUDIT: Wed Dec 22 16:18:19 2021: 3999: client 1 disconnected AUDIT: Wed Dec 22 16:18:19 2021: 3999: client 1 connected from local host ( uid=0 gid=0 pid=4552 ) Meanwhile, I restarted the X session (and removed old big logs), but I see the logs growing again. This could happen after a yum-update that day or could be caused by something else. Does anybody have a clue? Regards, -- wwp https://useplaintext.email/

firewalld: removing rich-rules based on its own list fails
by patrick+centos.org＠laimbock.com 22 Dec '21

22 Dec '21

Hi, I have some ansible roles which each create some firewalld rich-rules. For ansible idempotency I tried to remove any dns related rich-rules before creating the ones in the playbook. After some searching I came up with this: #!/bin/bash OLDIFS=$IFS IFS='' while read -r line; do firewall-cmd --zone=public --permanent --remove-rich-rule=\'$line\'; done <<< $(firewall-cmd --zone=public --list-rich-rules | egrep 'dns|53') IFS=$OLDIFS But this fails with for example: Error: INVALID_RULE: internal error in _lexer(): rule family="ipv4" source NOT address="46.23.XX.0/24" forward-port port="53" protocol="udp" to-port="60053" to-addr="46.23.XX.53" My googling & variations came up empty. Anyone know why this is failing and could possibly share how to make this work? Thanks! Best, Patrick
