[olug] ssh and Cox

[Trent Melcher]

The IP addresses Cox's uses for home users are dynamic and expire every
24hours, however, it has been setup so that the same IP will be reissued
back to you if its still available. Most times this is the case.  I had my
IP only change 1 times since they have been Cox and not @home. THis only
happened because my cable modem was unplugged for 4 days while I was on
vacation.  So the IP look available and probably got issued to a new
customer.

The ssh problem could be an issue with a firewall between you and the remote
machine.  My firewall at work timesout all sessions inactive for more than
20 minutes.  I found that using PUTTY and setting the Keepalive to about 300
sec. worked for me.

I'm a home user in west Millard.  Even though the IP is supposed to be
dynamic I've had the same since the last time I switched modems (over a
year ago).  In that time I've hooked up different PC's and routers to
the modem, shut off power for extended periods and replaced/rewired all
the RG cables in my house.  Every time it sees that modem mac address it
sends me the same ol' ip..  I'm using the Toshiba PCX2200..

Since were on the cox subject, has anyone else noticed the severe
restrictions cox has implemented on upload bandwidth since they
implemented their "network load balancing"?  I used to get an average of
150Kbps on upload and lately I can't do better than 30Kbps..  I know
they want to restrict running servers but this feels like dial up.  It
can take me up to 30 minutes to transfer large files to my remote server..
