I am a computer network engineer by training that started in the days of Novell NetWare 3.x. I now run an Internet service provider called Snowball Effect that I started with my brother Storm in 1998. Snowball specialises in wireless, hosting, and ADSL. Storm heads our web development team. Our offices are based in Technopark, Stellenbosch (close to Cape Town) South Africa where we also have a fully redundant data centre that we built from scratch.

My speciality apart from computer networking is business management especially operations. I have a intense undying passion for programming that started when I first laid my hands on a ZX-81. I am well versed in PHP and MySQL and I am enjoying learning Android. I am currently working on an app that I hope to launch by end 2012.

Stellenbosch is beautiful wine country in South Africa. Here are my favourite wine estates as of 8 Jan 2012: Glen Elly, Delheim, Muraie, Dornier, Ken Forrester, Meerlust, Thelema, Camberley, Jordan Wines, Thelema.

I see myself as ADD and BC. Before, I was ADD and now I am BC. My world changed when I discovered Basecamp.

comment MikroTik IPsec client Fortigate 'Received ESP packet with unknown SPI.'
Thanks for the answer. This problem mostly died down so we ask, what has changed? 1. We had 24 hour radius session-timeout. We removed this, more stability. 2. The client had a primary and backup firewall. They went to and from the primary a couple of times. They can't / won't give me the info but I pray or suspect they also updated some firmware. 3. The last time it happened we used a disable/enable everything for IPsec technique. This solved it. I really like your answer. I will remember this when it happens again. I need an ARP debug tool though.

comment exit: 1 [FATAL] Unable to connect to Asterisk Manager from /var/lib/asterisk/bin/retrieve_conf, aborting
Hi, thanks for your comment. This situation was a right old mess and I ended up completely removing Elastix and FreePBX and then just reinstalling FreePBX. I've concluded that Elastix is too hard to upgrade due to the way it's packages are managed so in future I'll just be sticking to FreePBX. I need to have easily upgradable systems.

comment Reduce SNMPd logging verbosity
I struggled to find the correct location on CentOS 6.5. It's not /etc/snmp/snmpd.options nor is it /etc/sysconfig/snmpd.options but actually it is /etc/sysconfig/snmpd. The ps aux | grep snmpd was really useful to see if the changes were working.

revised Plesk Unable to exec utility listmng: Cannot find grep program System error 2: No such file or directory
Since part of the problem is grep is missing I thought it wise to include a tag for grep.

I really don't understand why you were voted down as this appears to be a very valid question with regards to Plesk systems administration. I've attempted an answer.

comment How can I monitor hard disk load on linux
This is a very good question because we're always battling with this problem on Plesk servers. However, what is missing is how do you do it with SNMP?. It's fine to log in and check stuff, but one really needs historical data.

comment Apache freezing, How to detect which virtual host is getting hit?
This was such a lifesaver today! On a Plesk server you need to use lsof -u www-data | grep httpdocs | grep -v *.log because on a Apache Plesk shared server Apache has 100s of log files open, therefor the httdocs
