System integration

Had to do some system integration this week. It's not what I really like. System integration should better be called "taming wild pieces of bits and bytes". However, here are some Linux commands I needed that I will likely forget if I do not write them down:

• Log in to a remote system, specifying a user name:
  ssh hostname -l username
• Unpack a .tar.gz file:
  tar xvfz filename.tar.gz
• Restart sshd:
  /etc/init.d/sshd restart
• Restart Tomcat:
  /etc/init.d/tomcat restart
• Text based web browsers:
  1. w3m
  2. lynx
• find out which process is listening on which ports:
  netstat -p
• (really) kill a process:
  kill -9
• find out the process id of a java process:
  ps aux | grep java

Likewise, here are some Windows commands that might come in handy:

• Need to start a number of PuTTY sessions from one batch file? Use the start command:
  start putty -load session_name
start putty -load another_session_name
