no more ptys error on a Gentoo VPS 0

When starting screen, I would get a no more ptys error. I’ve had this error on Gentoo virtual servers run on both OpenVZ and Xen. After some quick googling, I came across the following fix.

echo 8192 > /proc/sys/kernel/pty/max
chmod 666 /dev/pty*

Voila!

lowerttls.sh 0

This script will lower the TTL on a directory full of zone files. I’ve used this with much success on many cPanel servers. I’m not sure how well it would work with other systems. My guess would be that it would work fine on any system using bind.

#!/bin/bash
echo Backing up /var/named
mkdir /home/named.backup
rsync -aq —exclude=proc /var/named /home/named.backup
echo Lowering TTLs…
sed -e ’s/\s14400/ 300/g’ -i /var/named/*.db
echo Reloading zone files…
rndc reload
echo Done!

You will of course need to update the serial as well. I suggest using updateserial from http://cplicensing.net

m4a2mp3.sh 0

My buddy rips and encodes his CDs with the AAC codec. This proves to be an issue if your mp3 player doesn’t support .m4a’s. Here’s a nice script to convert the m4a’s to mp3 using for loops and faad. You will need to install faad if you do not already have it installed.

#!/bin/bash
#
# Dump m4a to wav (first step in conversion)
#-ao pcm:file=<filename> instead.
for i in *.m4a
do
faad -o - "$i" | lame -h -b 192 - "${i%m4a}mp3"
done

You can change the bitrate to whatever you prefer. In this script it is set to 192kbps. This value is set by the -b flag.
