Title: cablevision Cablemodem timout
Post by: Aaron Held on April 26, 2001, 03:30:13 AM

I am trying to connect via a 3Com cable modem on the Cablevision network in NJ with no luck.  The dhcpcd keeps timing out, I increased the timout setting and played with some other hostname options but no luck.

Has anyone else experinced this?

I checked the command line being called by /sbin/ifup and it seems that it is always calling dhcpcd with a switch -h accountname entry

I went through the DHCP How-To's without much luck.

Any pointers?

Thanks,
-Aaron Held

I woke up this morning and the eSmith connected to the cable modem the first time.

I was plugging my laptop directly into the modem and renewing the DHCP lease fairly often to go online and read something.  When I do that eSmith cannot obtain a response. If I unplug the modem for a few minutes (not just a few seconds) everything works fine.

Thanks

Naturally. We have hundreds of people all over the world on various cable modem systems working perfectly.

The cable system uses DHCP, and will remember the MAC address of your laptop. You are lucky it is a few minutes - it is frequently many hours/days before your lease will expire.

Let e-smith handle the cable modem, and put your laptop on the e-smith internal interface.

Your right,
if I release the lease from the laptop it works much better.

I built the server at work and tested it against a netware DHCP server, I needed to bring it home to test the cable modem.  

Thanks again,
