"best").
I found no such example on google and don't know where to start...
Has anyone already done such a thing ?
Anyone can provide me with the pf.conf part and ifstated.conf ?
I've already use "ftpsesame" and play with the pf tags but I don't get
how to produce them with ifstated...
If you want to monitor servers and remove them from availability, use
PF tables to store address lists. Then use your script (shell, perl,
etc) to monitor them and delete them from the table if they become
unavailable. When they come back to life, just add them to the table.
