Today, I encountered some weird issues with a postfix/amavis mail server which was causing segfaults and memory paging errors. I was forced to bounce the server, but it wasn’t able to shutdown all of it’s services. That left me with the only option of calling the dedicated hosting company and requesting a hard shutdown. Shortly… Continue reading Policyd-weight issues with unclean shutdown
Today we needed to get some logging in place for a router and switch at a client’s office. This is a dreaded Windows only network, so I needed to find some options for a syslog server that would be able to run on Windows 2003 platform. Of course in the Window’s world, I’m always amazed… Continue reading Kiwi Syslog Server for Windows
Okay, I’ve been dealing with this problem FOREVER. On one box, my syslog-ng server, logrotate consumes 100% CPU for several hours, but will eventually finish. For this whole time, I’ve been thinking it’s a bad logrotate script, but I’ve never been able to isolate it. My recent attempt to isolate the problem, I used strace… Continue reading Logrotate lockup causing 100% CPU usage
On only two boxes I manage, I had problems updating net-snmp to net-snmp-5.4.2.1. During the compile I would receive the following failure message: chmod 755 ../blib/arch/auto/NetSNMP/TrapReceiver/TrapReceiver.so cp TrapReceiver.bs ../blib/arch/auto/NetSNMP/TrapReceiver/TrapReceiver.bs chmod 644 ../blib/arch/auto/NetSNMP/TrapReceiver/TrapReceiver.bs Manifying ../blib/man3/NetSNMP::TrapReceiver.3pm make[2]: Leaving directory `/var/tmp/portage/net-analyzer/net-snmp-5.4.2.1/work/net-snmp-5.4.2.1/perl/TrapReceiver' make[1]: Leaving directory `/var/tmp/portage/net-analyzer/net-snmp-5.4.2.1/work/net-snmp-5.4.2.1/perl' Traceback (most recent call last): File "setup.py", line 2, in <module> from setuptools… Continue reading Issues with net-snmp update on some boxes
Over the years, I’ve set up multiple firewalls and fileservers for clients and my own office. What I require is a server platform that is Gentoo Linux friendly with quality components and at an affordable price. Early on, I was a big fan of the Dell PowerEdge 400SC. I remember picking those up (without operating… Continue reading Dell PowerEdge SC Servers – great deals for linux servers
I wanted to tighten up my FTP service. Currently, I use and love vsftpd. Unfortunately, as far as I know, it does not support SFTP protocol, but it does support TLS/SSL handling. You will need to ensure that the vstpd has been compiled with ssl support. Here are my current USE flags for vsftpd: net-ftp/vsftpd-2.0.6… Continue reading Configuring VSFTPD for secure connections (TLS/SSL)
Starting Nov 8, I’ve been seeing fairly consistent segfaults from amavisd. I’m unable to determine what is causing it. Below is a listing of occurances in /var/log/messages. The server has been running fine (normal load – mail traffic is normal). Also I checked uptime (reboot was Nov.1) and recent emerges. The only emerges close Nov.8… Continue reading Amavisd-new starting to segfault?
Earlier this year, I was receiving logs stating that dansguardian could not connect to IPC socket. I just recently upgraded dansguardian (2.10-r1) and finally found the problem. I originally posted this issue in February on the Gentoo forums and didn’t receive any response. Today, I found the problem and the fix. Below is an example… Continue reading Dansguardian – Error connecting via ipc to log [SOLVED]
I was bummed out when the Gentoo maintainers removed osiris from portage due to inactivity. Because of this I had to ‘unmask’ this package to keep my system somewhat happy. I’ve been a big fan of osirisd/osirismd for a long long time. I think it’s the best file integrity checker out there. I always hated… Continue reading Osiris Update – Went Smooth
Started seeing some MSN Featured Offer Spam on one of my mailservers. The annoying part is that has a forged ‘from’ value to match the recipient. On top of that, it’s being sent from a secondary MX server which is allowing relaying to my domains. So I can’t block that server from sending it, and… Continue reading MSN Featured Offer Spam – Spamassasin rule to stop it
