  • If your account is enabled for multiple ressources, you have to do the changing procedure only once.
  • If you get an error while changing the password, check your environment. Passwd is a simple bash script located in ( /opt/system/wrappers/passwd on Vulcan or /opt/passwd on change.hww.hlrs.de).


Todo so following steps are necessary:

Login on an frontend system which is accessable for you.

Vulcan users:

  ssh –l <your login> cl5fr2.hww.hlrs.de
  Run the passwd command to change your password. Please read information and watch output of this command. On success following text is displayed: Password changed successfully.
  Wait for a minimum of 20 minutes to redistribute the password
  Remove your ssh-keys (see below)
