linux tips

• to mount windows share on linux (ubuntu 10.04)
• sudo apt-get install samba smbfs (2 installs needed)
• using smbmount
  
  
  
  sudo smbmount "//11.145.120.61/system" "/home/rxxxx/z-shares/chris-share" -o 'user=rxxxx,pass=15'
  //for Read with Write permission
  sudo smbmount "//11.145.161.9/Users/rxxxx" "/home/rxxxx/z-shares/vdi/raj" -o username=rxxxx,password=xxxxxxxx15,rw,uid=1000
  //make sure use "id" command to look for ur UID 
• look for who is using port 8410
  
  
  netstat -tulpn | grep '8410'
• look for details of process with 'jboss' in it
  
  
  ps -afew | grep jboss
• ssh to a machine with jboss as user to machine devmachine, using ssh listening(telnet) port 8841 configured, default is 22
  
  
  ssh -P 8841 jboss@devmachine
  which prompts for password,
  
• to prevent typing password (from chris machine) everytime you can copy public key to remote box as follows
  
  
  copy from local ~/.ssh/id_rsa.pub to remote machine
  
  
  using scp -P 8841 src destn
  scp -P 8841 ~/.ssh/id_rsa.pub jboss@devmachine:/home/jboss/chris_rsa.pub
  
  
  then add this key to authorized keys file in remote box as follows
  cat /home/jboss/chris_rsa.pub >> ~/.ssh/authorized_keys
  
  
• if you do not have rsa (ssh keys) on you r local you can do as follows details about ssh
  gitosis
  
  
  ssh-keygen -t rsa

The defaults for the ssh-related commands can be altered for each account in a configuration file ~/.ssh/config (there is also a system-wide file, usually /etc/ssh/ssh_config). Each entry starts with a Host keyword.

Host *panix.com
User suominen
Compression no
Port 8841

If you want to run commands automatically when ssh login

just put this in ~/.bashrc or /etc/bash.bashrc if you want this for all users:

if [[ -n $SSH_CONNECTION ]] ; then
    echo "I'm logged in remotely"
