I spent hours trying to get mod_bandwidth to work simply because I have used it for years. But now with Apache 2.0 times have changed and there is a better option for Linux and it’s free. The new mod to regulate bandwidth and more is called Mod_cband I’m not sure what cband means but I [...]

Apache 2.0 makes raising the max client from the default 256 hard limit a little harder now. If you have cpanel then it’s even a little harder or I should you just need to know what to do, figuring it out is a shot in the dark. One main difference is you have raise the [...]

Fixing DNS is a tricky thing, with cpanel there is a couple steps to try first. DNS failed you are not sure why, try this first: /scripts/cleandns /scripts/rebuildnamedconf Still not working, try this: /scripts/rebuilddnsconfig /scripts/fixdns Basically DNS has about 5 files that need to all be in sync for named DNS to run. I highly [...]

You could also use find and sed, but I find that this little line of perl works nicely. perl -pi -w -e ‘s/search/replace/g;’ *.php -e means execute the following line of code. -i means edit in-place -w write warnings -p loop Example I had the following style sheet in a section: <link rel=”stylesheet” type=”text/css” href=”../includes/style.css”> [...]

The trick is to limit I/O bandwidth for rsync. The –bwlimit option limit I/O bandwidth. You need to set bandwidth using KBytes per second. For example, limit I/O bandwidth to 10000KB/s (9.7MB/s), enter: rsync –delete –numeric-ids –relative –delete-excluded –bwlimit=10000 /path/to/source /path/to/dest/? 10 megs a second is plenty of speed and will keep the server running [...]

Today I was transferring files through rsync it was taking forever, my guess was the new server or old server was out of memory so I killed some procs and even rebooting the server but still it was crawling. So I thought I would think out of the box and after a couple trial and [...]
