Re: [CentOS] Problems with motherboard support? INTEL DP43BF
Hi John, I agree that realtek are far from something we could cold call a good product. But I have similar setup (with different motherboard) working without a flaw. All your arguments are valid and worth investigating. The local lan (eth0) is 100Mbits. Both eth1 and eth2 are realtek (same model/chipset). I'll have a look at the BIOS settings and removed the vga mode from grub and make sure lm_sensors is installed. Besides this I am not sure what else I could do. The main question is am I dealing with a falty component (motherboard, cpu, memory, NIC) or some other OS/Software bug?

Re: [CentOS] Problems with motherboard support? INTEL DP43BF
Hi John,
I'll have a look a that. This seems odd because, if I understand correctly,
those settings would only affect if/when the system is idle and the lockups
occur during regular/busy hours.
BUT... they should be off anyway.

If you need to fix one end of the cable, you have to make sure it's the same as the other end. If you use the standard color scheme, that is not a problem. What IS important is the pairing. In your second example, you have messed up the pairings. This may work, but is not optimal. You could do something like this: white-brown, brown, white-orange, blue, white-blue, orange, white-green, green But there is really no reason for it.

[CentOS] Server unresponsive until reboot, memory exhausted
I'm having an issue with an apache web server running the latest CentOS5 kernel (this issue is not new to the kernel). After a few days/weeks of running the server will become unresponsive and will require a physical reboot in order to come back online. The system is so unresponsive when the issue occurs that login at console is not even possible. I have atop installed and have looked back before the crash to see what happened process wise and I can see the http starts using a lot of memory and CPU usage. The vmcommit jumps from 1.8 GB to 4.8GB in a matter of a few minutes. The VSIZE of the httpd process jumps from 8.1GB to 36.9GB. So apache is doing something -- but how can I get historical data for this? I also see that paging is very active, probably why the server is unresponsive. I have looked through the apache logs and system logs and there is nothing obvious that is consuming all that memory. I know of the server-status module for apache but that is only useful if you can get to the server during the crash (I can't) and doesn't have any historical data. The issue occurs seemingly randomly, last time in the middle of the night with little or no user traffic.

[CentOS] Kickstart Network Configuration Issues
Hello all, I've been struggling with an issue with my kickstart configuration for a while now. My kickstart files are stored within the initrd image. What I would like to do here, is when the kickstart first starts up, I want it to grab a DHCP address (it does at the moment) so it can grab all of the necessary installation data off the net. Then, at some point _IN_ the install process, I'd like to have it query for manually input network settings. Here is my current kickstart script: auth --useshadow --enablemd5 bootloader --location=mbr zerombr clearpart --all --initlabel text firewall --enabled --port=22:tcp firstboot --disable keyboard us lang en_US logging --level=info url --url=http://mirror.nexcess.net/CentOS/5.5/os/x86_64/ reboot --eject rootpw --iscrypted xx selinux --enforcing skipx timezone --isUtc America/Detroit install part /boot --bytes-per-inode=4096 --fstype="ext3" --size=512 --ondisk=sda part swap --bytes-per-inode=4096 --fstype="swap" --size=2048 --ondisk=sda part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sda part /backup --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sdb network --bootproto=dhcp --device=eth0 %packages --nobase @core system-config-network-tui %post echo "nameserver 4.2.2.1" > /etc/resolv.conf echo "nameserver 8.8.8.8" >> /etc/resolv.conf # write netconfig script cat << EOF > /bin/netconfig #!/bin/bash # check if user is root if [[ \$EUID -ne 0 ]]; then echo "This script must be run as root" 1>&2 exit 1 fi # run system-config-network-tui /usr/sbin/system-config-network-tui # set variables eth0f="/etc/sysconfig/network-scripts/ifcfg-eth0" eth1f="/etc/sysconfig/network-scripts/ifcfg-eth1" netcfg="/etc/sysconfig/network" # turn on eth1 if it has an address, remove gateway.. shouldn't be set here # anyways if [ -f "\$eth1f" ]; then if grep -q "IPADDR" \$eth1f; then sed -i 's/ONBOOT=no/ONBOOT=yes/' \$eth1f sed -i '/^GATEWAY/d' \$eth1f sed -i '/^HOTPLUG/d' \$eth1f fi fi # move gateway from ifcfg-eth0 to /etc/sysconfig/network if [ -f "\$eth0f" ]; then e0gw=\$(grep "GATEWAY" \$eth0f) sed -i '/^GATEWAY/d' \$eth0f # check to see if the gateway is already set. if it is, delete it first if ! grep -q "GATEWAY" /etc/sysconfig/network; then echo \$e0gw >> \$netcfg else sed -i '/^GATEWAY/d' \$netcfg echo \$e0gw >> \$netcfg fi fi EOF chmod +x /bin/netconfig At the moment, I have a not-so-elegant script written to the server to be run manually after install.

You're not failing to understand anything. The init.d/privoxy script
you have is broken. While https://bugzilla.redhat.com/show_bug.cgi?id=597732
was reported against a different problem, the corrected initscript it
contains should fix your problem as well.
It might be worthwhile to report a new bug against privoxy since the
failure to do a reload after logrotate is a more serious problem than
the one reported in #597732.

My suggested approach is to always use DHCP, and set DHCP reservations on your DHCP server to consistently assign the same IP to the same client's MAC address. That way, you can assign the IP and hostname in your local DNS or /etc/hosts or NIS hosts table or whatever, and get it set consistently. The only missing feature this way for CentOS 5 is the list of automatic search domains, for which the network setup tools provide no DHCP compatible hook and the DHCP is too old to follow the years-old RFC and handle multiple searchable domains. The answer to that is to manually put a "SEARCH" setting in /etc/sysconfig/network. > url --url=http://mirror.nexcess.net/CentOS/5.5/os/x86_64/ If you're going to be doing this a lot, set up a local CentOS mirror and take most of the load off the external servers.

If folks like, I'll try to dig up my tools. The "system-config-network-tui" script is, sadly, pretty useless for auto-provisioning.

This is privoxy rpm that I created myself by copying the spec file from
a Fedora srpm and substituting the latest version (3.0.17) of privoxy.
The logrotate configuration file for privoxy disappeared in the latest version
so I had to copy it in from an older version and haven't yet gotten around to
figuring out how to integrate it into the rpm properly.
Since the rpm I'm using isn't "official" but rather is just something I've
slapped together I don't think a bug report would be particularly useful.
I got tired of privoxy crashing and want to see if a substantially newer
version will crash less.
The behaviour with system-config-services varies under Centos from what is
contained in that bug report. Using the init file that came with the source
tarball I see that system-config-services doesn't even try to report its
status, but rather simply says "Usage: /etc/init.d/privoxy {start|stop|
restart}" in the Status window.

I'm more of a c-shell guy but a "for loop" uses white space (either newline or
space) as the delimiter. One of the other responses suggested an alternative
loop construct. Alternatively, the find command with the appropriate commands
in either a script file or just following a -exec. Something like:
find . -type f -exec `new = `echo {} | tr [bad chars] [replace]`; mv {} $new;
echo "old: {} new: $new" \;
The above needs lots of work but this way you don't have to visit each
directory.

That's the problem that was reported in the Fedora bugzilla. What you've
built is an RPM with a logrotate.d file that requests an action ("reload")
that the init.d file does not support. It doesn't work, but the logrotate.d
file is ignoring the error and discarding the error message.
system-config-services is having a problem because the "status" action is
not supported. If you were to substitute the more complete init.d file
that was attached to that bug report, I believe that would take care of
both the logrotate problem and the status report problem.

[CentOS] appliance to embed Centos
I'm looking for some kind of appliance like box, maybe something like this:http://www.soekris.com/net5501.htm on which I could deploy iptables based firewall/openvpn/DNS and other local network services in a wide area network. I would probably install on a flash device. I would prefer something that was relatively easy to install on, or at least has been used with CentOS before, where I'm not needing to pull my hair out finding working drivers, building custom kernels etc. Though I might spend time down the road to come up with an extremely minimal install, for rapid deployment in the first round, I'd like to be able to do a pretty standard install and have a full featured CentOS system that I could logon to and use for local network administrative tasks. I could use something like a Mac mini, but my sense is there are are probably less expensive and more suitable devices. - Two ethernet interfaces - working drivers for CentOS - flash - enterprise quality (i.e. not some flakey little home router device) - fast enough to do openvpn encryption on WAN links ranging from 50mb to 100mb Though I do want enterprise quality, my sense is to make the device affordable enough that I could keep spares on site for backup purposes. I would appreciate anyones experience with deploying such a setup. Thanks, Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] appliance to embed Centos
Hi Nataraj, Take a look at the Intel Atom platform. The D510MO & D945GCLF2D run beautifully under CentOS and I've used both as firewalls in the past. Another linux based firewall system I use has users reporting the two boards above supporting AV, Content Filtering (proxy), etc on 50Mbps FIOS connections down in the states. If you want multiple onboard nics, the Jetway boards are also supposedly decent. I've never used one but users from the same site have reported sucess with these boards, and the optional 3x1GB nic still fits within the ATX backplate. Only downside to these boards, both Intel & Jetway, is they seem to prefer Realtek chipsets onboard. Jetway I understand because of price points. Intel I don't as the Pro/1000 is a rock solid nic. That said, I've never had a problem with flaky drivers or hardware from Realtek. Maybe I'm just lucky. :-) -- Drew "Nothing in life is to be feared.

They are in the UK, but they do have quite a large selection and they are all custom configurable. Unfortunately, their celeron system, with shipping to the US cost me, $700 as much as a Mac Mini with a core 2 Duo and there are better service options for the Mac Mini in the US, though the Celeron is an industrial rackmount solution. I wouldn't really call the Mac Mini an Enterprise solution. For $650 I could get a basic Dell R210 with an X3430 2.4Ghz dual core Xeon. For $500 I could get the R210 with a Celeron. I guess Dell wins on this one. I suppose one real advantage of these small embedded appliances, if they are fast enough for the application, is very low power consumption. I like that for my home firewall. Another advantage is they are easy to ship around. Thanks, Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
