Link UpTime Information
 

Is there a way of establishing how long a link (to the cable modem) has been alive?

I am running a job on my PC which grabs a screen from the internet using a DOS browser (lynx) this job failed as the grabbed screen didn't contain a line of text I was expecting but then my job emails me at work!

I never got the email so I assume the link from the cable modem to the outside world died. I would like to check this before I write another script to check the 1st is still alive when it should be!

Hmm. For most SACMs you should be able to do an SNMPGET of the sysuptime OID and parse that for the time. For STBs and non-SNMPable SACMs you're SOL, unfortunately. Try running a continuous ping to your gateway IP and measure the time since the last unsuccessful ping.
