Starting out
mon is the name of the monitoring program that we are using to monitor
the internet services. To start mon, login on the op machine with:
login: op
password: op
it will then start up netscape to the page that shows the mon results.
What to do when something goes red
During working hours, or if something goes really wrong, try to contact
me (Martha) at x2554 or 053-565-014 or 02-563-8652, or Boaz at x2581 or
050-652-188.
If a service goes down and stays down, switch to the backup machine.
Switching to a backup
To switch to the backup firewall, simply unplug the ethernet cables from
the fw that is currently connected, and switch them to the fw that was
not connected.
To switch to the backup for any machine other than the firewall:
- unplug the ethernet cable from the machine which is not working.
- move the phone line from the machine which is not working to the
shadow machine (except in the case of forumowl, which does not have a
phone line attached.
- boot the shadow machine to the appropriate configuration
When the shadow machine boots, it will print a prompt that says:
LILO boot:
When you see that prompt, type one of the following, depending on which
configuration you want:
- forum (discussion groups server)
- mail (external mail and dns server)
- test (normal configuration - not backing anything up)
- shaar (shaar haarayot - connection between external and
internal mail)
- katan (internal mail server)
