Fantastico, PHPList and blank pages

2009-01-12T02:09:00.001-08:00

I’ve lately had a few clients complaining about their PHPList installs not working properly when using Fantastico, I tried it out myself and it does indeed seem to be somewhat broken. Usually when you go the adminstration page, it simply shows and empty page and if you view the source for that page, it contains something along of these lines: The cause of

Helpful cPanel included application

2009-01-12T02:08:00.002-08:00

cPanel may have some very annoying bugs sometimes however there are very useful bits of it that can help in general system administration, dealing with a very busy server and trying to terminate an account that has high disk usage will make the load averages go sky high however thanks to this neat little application provided with cPanel, you can forget about freaking out on high server load.

Migrating LVM volumes over network (using snapshots)

2009-01-12T02:08:00.001-08:00

We run a big share of Xen virtual servers spanned over multiple servers and if you want to use the full or best capability of Xen, I would suggest LVM (Logical Volume Manager), it makes life a lot easier, especially for those who do not run a RAID setup (We run RAID10 on all VM nodes) as you can split the partition over multiple hard drives. I’m not going to cover setting up the LVM as there

AACRAID based controllers timing out / aborting / SCSI hang

2009-01-12T02:06:00.000-08:00

We’ve been lately starting to use more Adaptec RAID controllers rather than 3ware RAID controllers. 3ware has been nothing but trouble for us, dropping hard drives, even RAID5 arrays are running slower than a regular hard drive with no RAID. Our latest issue was a server just simply having a Kernel Panic when using high IO, our experience with 3ware RAID controllers & Linux is terrible. On

/tmp clean-up script modification, sessions dying with PHP

2009-01-12T02:05:00.000-08:00

It seems there there was a little flaw in the script that I wrote a while ago, any PHP sessions on the server will timeout/die after 1 hour if you run that as an hourly cronjob, I have made a small modification to the script. The only small modification is that now, it deletes all sess_* files that have not been accessed for 5 days therefore are probably just sitting there and never going to

Migrating cPanel reseller accounts with root WHM access

2009-01-12T02:00:00.001-08:00

We have a few clients that were WHM resellers and upgraded to VPS with root cPanel, however there is no main easy way to migrate WHM reseller account to a root account under WHM, that’s where we started playing around and making our own script. You need root access to the source and final server to do this, this looks like the fastest way to do this at the moment. First of all, we need to

Horde broken or not working correctly on cPanel server

2009-01-12T01:59:00.000-08:00

Simple, short & sweet post, this should easily fix any problems you’re having /usr/local/cpanel/bin/update-horde --force Also, this might be useful to run hourly, I leave this on our servers “just in case”. (mysqlcheck --auto-repair eximstats ; mysqlcheck --auto-repair horde) >/dev/null 2>/dev/null

cpanel Backup Clean up

2009-01-11T23:31:00.001-08:00

One of the major pluses of cPanel that it doesn’t delete the backup of the account when terminating an account and neither it does remove it on the next backup run, while that can be a good thing if the customer comes back, on the long term, the backup drive starts to slowly run out of space and eventually these big accounts that have been stored for a while will need to be removed. I had to
