[oclug] Auto ifdown / ifup

[Scott Connery]

For some reason ... unbeknownst to me, Rogers @ Home likes going down 
temporarily o a regular basis (or at least the modem loses connection). When 
the net goes down my server (RedHat 7) hickups. Eventhough the IP stays the 
same, I cannot access the inetnet until I run "ifdown eth1" and "ifup eth1". 
It may be due to a requirment for DHCP authentication, I am not sure.

Is there a way to either:
-constantly ping the internet, and if it is down, to run a combination  
ifdown / ifup script, when the connection is restored,
OR
-to reset the timing for the leasing of the DHCP lease. (It may be that 
although my IP seems static, the lease still runns out).
OR
-any other ideas....?

Thanks,

Scott
