Re: [CentOS] Excluding file systems from autorelabel
- Original Message - | It is possible to use semanage to label the files correctly and to | persist after reboot see man pages for FTP | Hope this helps | Russell I'm really feeling dense today. I can't find anywhere in the FTP man page anything related to SELinux labels. I've google'd for stuff related to setting the context but that is NOT what I want to to. I want to strip the context entirely so that autorelabel won't look at the files and directories under exports and attempt to apply labels and I thought that semanage fcontext -a -t "<>" "/exports(/.*)?" would do just that. It seems quite obvious that I'm either mistaken or that I'm missing another step. Once I do this must I also run restorecon or some other command? -- James A.

Reading the arp_filter settings it does match what we're experiencing, but I've never seen it before, but haven't ever been looking for it.

I added iptable rules for ports 25, 110, 143, 587, 993, 995, & 4190. I
believe those are all the ports I am using for this (SMTP, IMAP, POP3, &

Nope, no common log!! Just mysql, postfix, http. dovecot and amavis-new logs.
Turn up logging. Most likely the answer is there. (hint none of what I
suggested logs to /var/log/messages). Keep in mind all pfa is, is a web app.
When configured correctly, it knows how to talk to all of the associated
components but logging is still to the native logs of each of the respective
components.
When I am setting up a new instance of pfa I generally turn mysql, dovecot
and amavisd-new logging up so that I can see any errors. Running something like
tail -F /var/log{messages,maillog,mysqld.log,httpd/*,maillog} should get you
enough information for you to be able to see what is going on.

[CentOS] screensaver: waiting for darkness
I'm using the default desktop for CentOS 6. My screensaver is set for blank, 5 min, no locking. In the seconds during which the screen fades to black, I cannot make it come back. Neither the keyboard nor moving and clicking the mouse has any affect. Until the screen goes black, I cannot do anything with the computer. How, if at all, can I change that? -- Michael henne...@web.cs.ndsu.nodak.edu "Darkness theare and nothing more." -- Edgar Allan Poe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Yum search for unavailable file!
Hi, I'm trying to install ant on my centos 6.3, this is behind a http (only http and not ftp) proxy server. after execute yum install ant, I got some error which indicate mirror speed is extremely low, less than 1bps! and go to test another mirror and error cycle starts again. this is error: "http://wftp.tu-chemnitz.de/pub/linux/centos/6.3/updates/x86_64/repodata/e2e0a4ecd0b1548bb176caec4fd68091c8a2b7409872e3ccf2fd3669ffd1cbcd-filelists.sqlite.bz2: [Errno 12] Timeout on http://ftp.tu-chemnitz.de/pub/linux/centos/6.3/updates/x86_64/repodata/e2e0a4ecd0b1548bb176caec4fd68091c8a2b7409872e3ccf2fd3669ffd1cbcd-filelists.sqlite.bz2: (28, 'Operation too slow.

To what type of equipment are your ethernet devices connected? Are they both connected to the same device? I've seen some devices (particularly 2Wire) that do not like two interfaces from the same system connected to them. You note that eth1 is on a 169.xx IP, and earlier in your email, you note that it's non-routable. Perhaps that's not the wording you wished, to use, or perhaps you meant that it's not routed out to the internet, however, 169.xxx.xxx.xxx is most certainly a "routable" IP block, as far as internet standards go. The only "non-routable" (i.e. reserved for private networks) IP blocks are: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 While certainly not an undertaking to be done lightly, you may wish to renumber your internal network. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] CentOS 5.7 eth0, eth1 and arpwatch flip flops
Dear all, Has anyone experienced this whilst running DRBD over eth1 between two CentOS 5.7 servers? eth1 is a private IP address, unroutable. eth0 is the public address. CentOS will reply sometimes once every 3 days or every 14mins~ saying "My public IP is on eth1" to arp requests when it's not, it's eth0. This freezes traffic and causes issues. We've looked at arp* /etc/sysctl.conf etc. and arptables, but wondered if anyone had a recipe? We have this already which didn't help as it happened Christmas Eve too as we kept eth1 up for a few days to test: # For the dual interface - 06.12.12 net.ipv4.conf.eth0.arp_filter = 1 net.ipv4.conf.eth0.arp_ignore = 1 net.ipv4.conf.eth1.arp_filter = 1 net.ipv4.conf.eth1.arp_ignore = 1 net.ipv4.conf.all.arp_filter = 1 eth0 and eth1 are on the same VLAN/broadcast domain, but eth1 is a 169.xx and eth0 is a routable public IP. We're having to shut eth1 down and bring it up for sync at night. Thanks, Gavin. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Excluding file systems from autorelabel
I'm trying to find a way to exclude file systems during the autorelabel process. I have a file system (/exports) that has tens of millions of files on it and I *know* I don't want it relabeled. I've tried semanage fcontext -a -t "<>" "/exports(/.*)?" and it seems to insist on relabeling that file system. I also tried to see if there was a /.autorelabel_exclude option as I saw some patches but can't seem to find indication of them anywhere (perhaps I missed it). I really need to make sure that I can exclude these massive directories if at all possible. Any help? -- James A.
