DNS lookup delay with centos & postfix
by Steve Lindemann 26 Jul '12

26 Jul '12

I'm a bit baffled by this and I'm looking for ideas... background: two DNS servers (ns1 & ns2)(64bit CentOS 5.8) one email server (64bit CentOS 5.8 & postfix 2.3.3) one nagios server (64bit CentOS 5.8 & nagios 3.3.1) situation: - all servers configured to use both DNS servers for lookups - ns1 server down for hardware problem - nagios alerts that smtp on email server taking longer than 2 seconds to respond - nagios alert for smtp on email server clears when ns1 returns to service - when I use dig from the email server command line there is no problem or delay when ns1 is offline. It worked without a hitch using ns2. Anyone have any ideas for why nagios would have trouble testing smtp on the email server when the primary dns goes offline? I'm not even sure where to look or who else would make sense to ask the question of on this one. I'd appreciate any insight anyone out there has on this. -- Steve

using ip address on bonded channels in a cluster
by Steve Campbell 26 Jul '12

26 Jul '12

I'm creating a firewall HA cluster. The proof of concept for the basic firewall cluster is OK. I can bring up the cluster, start the iptables firewall, and move all of this with no problem. I'm using Conga to do all of this configuration on Centos 6.3 servers. To extend the "HA" part of this, I'd like to use bonded channels instead of plain old NICs. The firewall uses the "IP address" service for the outside firewall IP addresses. Each server behind the firewall is NATted to one of these external IPs on the firewall's external interface. I'm not seeing how I can use bonded channels anywhere for these "IP address" services. Part of the problem is that Conga will "guess" at which interface to place the ip address service upon. In the case of bonded channels, I don't think Conga is even aware of the "bondx" interface, and Conga only uses interfaces like eth0, eth1, etc. I realize that the sysconfig network scripts will come into play here as well, but that's another problem for me to tackle. Does anyone have any experience with bonded channels and Conga? I could sure use some help with this. Thanks, steve campbell

wlan and macvtap?
by Darod Zyree 26 Jul '12

26 Jul '12

Greetings, This is my fist time posting to a mailing list. For the past few days I have been trying to mimic my former windows workstation with a centos 6.3 workstation at work. I have gotten really far but am now facing an issue I cant seem to solve on my own. My former workstation had vmware for running my virtual machines. Most of the time I would run just two virtual machines, but sometimes more, and each virtual machine would have access to one of my hosts network interfaces. I have two, one connected by cable to the corporate lan and one wireless interface connected to an access point which gives me and my colleagues direct access to the internet. After having read some documentations I decided upon using "macvtap" in VEPA mode for my guest virtual machines. This, to me, seem to be the most clean solution without having to create bridges, this way when I start a virtual machine the macvtap interface is created automatically. Plus I have read that NetworkManager does not play nicely (yet) with bridge interfaces and the virtual machines are accessible from their connected network environments. This did not work at first because I had not yet put my physical network interface in to promiscuous mode. Was I wrong in expecting this to be done automatically? Since my macvtap interface requires this to work "properly"? After having set the corporate lan network interface, in to promiscuous mode my virtual machine received an IP address and all was well. However this did not work for my wlan interface after having done the same. It too was set in to promiscuous mode but the virtual machine is not receiving an ip address from the DHCP server, which is the access point. I changed the network settings on the virtual machine from DHCP to manual but that too did not work: no network communication. Does macvtap not work with wlan interfaces? Or am I doing something wrong. I am using centos 6.3, with kvm, libvirt and virt-manager, have not used any none standard repository for installation or updates. Regards, Darod Zyree

A "problem" is a crashing kernel or buggy drivers. My opinion after this experience is that it'd help for CentOS to include system-config-network-tui as part of the base install. That is my honest opinion about this experience. It'd have saved me from some minor annoyance, albeit an annoyance nonetheless. Just think the opposite: what would be the expense-damage of including it as part of the base install?. Would it: 1. Break the OS 2. Make things easier for people who end up in the same situation I did. 3. Affect the balance of the Universe. ;) Your choice. I think 2. FC

Let's just package a tarball and let users unpack it manually. In fact, are you advocating for the removal of system-config-network-tui ? how about removal of all non-modal text editors like joe ? let's force everyone to "think" in 'vi'... *sarcasm* FC

Can someone help with SpamBayes problem?
by fred smith 26 Jul '12

26 Jul '12

I've posted to the SpamBayes users list, but there seems to be no traffic there, so I've had no replies. If there is anyone here using SpamBayes, I'd appreciate some advice or at least suggestions.... I'm running Centos 5.8 here. Day before yesterday I decided to look and see if there was a newer SpamBayes than I was then using. lo and behold, there was. I was using 1.1a4, and there was a 1.1a6. so I downloaded and installed it. bad move. having done that, I now have no spam filtering at all. I run my own sendmail mail server here, and it uses procmail to deliver. Procmail invokes one of the SpamBayes tools for every email, and it adds a X-SpamBayes header with its determination of spamminess. except that now it doesn't. the nightly retrain event (a cron job) also fails, with complaints about invalid syntax in: File "/usr/lib/python2.4/site-packages/lockfile-0.9.1-py2.4.egg/lockfile/linklockfile.py", line 6 from . import (LockBase, LockFailed, NotLocked, NotMyLock, LockTimeout, ^ SyntaxError: invalid syntax a little snooping around at python.org shows that the "from . import" syntax was added in python 2.5. However, on Centos 5.8 we still have Python 2.4.3. (never mind that the docs on SpamBayes claim it will run on Python 2.2, they're plainly wrong). So, I tried to reinstall SpamBayes 1.1a4 over top of what I had. It appeared to install (to the extent that the info displayed when the installer runs means anything), but it doesn't work either. no spam filtering, no nightly cron job. I'm guessing I'll have to figure out, in detail, which files were installed by the 1.1a6 installation and go remove each individual one then try reinstalling 1.1a4. Unless someone can suggest a better path to try. I'd appreciate any suggestions any of you may wish to make. thanks in advance!

My own, very un-scientific evidence is that once or twice, manually editing has given errors that I don't believe were due to typos.

My point is that Fedora is trying to make it the default and pushing people to use it rather than the more traditional tools.

My machines usually have 6 interfaces or so, are set up in one location, then moved to the production location with the final configuration (including IP's) done by operators that are better at windows than linux.
