I have always problems with capture rare problems with networks because simple programs such as ping or mtr doesn't logs problem in time scale.

I know that I could use SNMP and MRTG or similar tools but those are to big for small scale problems especially for particular server at client's network.

That's why I create simple script which logs timestamp when ICMP packets are dropped. Moreover it use standard tools such as ping and sh.

As usually use it on your own risk :)


#!/bin/sh

# Simple script for parallel ping

Well I had enough of looking for EOL conversion solution every time when I realy need, so I decided to solve this problem once and for all. Below is my one-liner maybe it will help you also :)

find ./ -type f -exec perl -i -p -e 's/\r$//' {} \;

Argh... more sophisticated tool you use more problems you can face. This time apt-get give me some headache. The solution was to do the man's job using low level tool (as usual ;)) called dpkg:
cd /var/cache/apt/archives/
dpkg -i --force-depends libc6*
