It worked once and once only

It worked once and once only

Post by Shaw » Fri, 27 Sep 1996 04:00:00



Tha problem is I could never get modem response any more with the command
line "ppp-on &"--the modem just responded the very first time I used
ppp-on!!
When I use "tail -f /var/log/messages" to follow what was going on during
ppp-on script processing, I noticed the responses to AT, ATZ.. were
"alarm";
and it also reported that my serial connection was looped-back and the
script
was aborted itself soon. At this point I could still used minicom or
kermit
to dial out without any problem.

I thought I might messed up with some file during ppp setup so I
reinstalled
the N set of Slackware (3.1) again. I set up the ppp as I did before and
I first used minicom to dial in and quited without resetting and the
results
of "ifconfig" and "ping"  all looked ok. I then tried ppp-on script which
responded to ATZ, dialed correctly and proceeded to login. Again I did
not
setup correct word for "username" so the script stopped. But when I tried
to ppp-on again, guess what, modem was not responding to AT command
again.
minicom is still working fine.

Can anyone help me or point me to a help source? Thanks alot.

1. pump dhcp client : works once ... doesn't work again.

I posted this a while ago but got no response, one more try ....
I'm on the RCN cable network here in Boston (somerville to be exact)
and have been trying to get my two debian linux machines (one sparc,
one x86) online consistently for the past week.  They both sucessfully
worked when I first plugged them in and made the network settings get
the ip through dhcp ...

the sparc linux machine was working fine until a little while later
when it just went off the network completely ... I then plugged the
network cable from the modem into the x86 machine and it worked fine.
After a day of the x86 machine being off the cable modem ( had to use
a windows machine for a little while ) I could no longer get an ip on
the x86 linux machine through pump/dhcp.  

the errors I'm getting in syslog look like this :

I tried different combinations of pump commands to try and get it to
work but ... no luck :
pump -i eth0
pump -R -i eth0
pump -v -R -i eth0

tried releasing it and then renewing it
pump -i eth0 --release
pump -i eth0

I'm also cycling the power on the Toshiba cable modem before I
request ip addresses  ( unplug - plug back in ).  Is there some sort
of cache that pump has the ip info on ?  I just don't get it ... if it
worked the first time why won't it work again?

from what I understand rcn doesnt need a hostname sent to the server.
I just dont get why it worked once on each machine - but not again.
Anyone have any ideas ?
