There are three IPSs that can can be used to reboot computers in the event they are unreachable using normal (ssh/vnc) methods.

They are:

ipshb.phys.utas.edu.au
ipske.phys.utas.edu.au
ipsyg.phys.utas.edu.au

They have a fairly straightforward web interface. The username for all three is 'administrator', and the password should be the standard root password, however one may be non standard. If you run into any problems you should consult your on-call person.

You may receive a 'Server is Busy' and/or 'There may be someone else logged in to the ips' error. In this case you can still telnet in:

telnet ipshb.phys.utas.edu.au
*******
/Off 5
/On 5
/X

In this case we are restarting plug 5.
