What if something's not right?

Please note: The FAQ pages at the HPCVL website are continuously being revised. Some pages might pertain to an older configuration of the system. Please let us know if you encounter problems or inaccuracies, and we will correct the entries.

The first time you log in with ssh, you might receive a message like:
The authenticity of host '130.15.59.64 (130.15.59.64)' can't be established. RSA1 key fingerprint is bla::bla::bla
Just answer the question if you want to continue with "yes". The message will not re-occur.

If for some reason your encryption key is not recognized anymore by the target machine, you will get an error message such as:
@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: HOST IDENTIFICATION HAS CHANGED! @@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the host key has just been changed. Please contact your system administrator.

Before you contact the system administrator, you might want to move the file $HOME/.ssh/known_hosts to something else and try again. If you still can't get in, contact the system administrator.
