I currently have our 2100 hardwired to a linux machine using the
tty00 port as a SLIP connection. The connection works just fine
ping works bi-directionally.
On the alpha end, I have the rc.config setup to activate the SLIP
on powerup.
OK. now I want to separate the machines. So I undo the null modem
and hook modems up to each machine.
Before on the linux end I had the following to establish the connection
slattach -p slip -s 19200 /dev/ttyS0 &
ifconfig sl0 10.10.150.24 pointopoint 10.10.150.25 up
route add 10.10.150.25 dev sl0
echo "SLIP Connection with DEC Established"
It worked fine hardwired, but now with modem connected, I need a way to
dial the modem, so I tried using dip.
#dip -t
dip>get $local 10.10.150.24 (this is IP assigned to the local
end slip)
dip>get $remote 10.10.150.25 (this is IP assigned to the remote
slip)
dip>netmask 255.255.255.0
dip>port /dev/ttyS0
dip>speed 19200
dip>dial phone#
dip>mode slip
#ping 10.10.150.25
no response, if I "ping 10.10.150.24" from the remote end, no response.
if I do a ps aux, I get the command line = "-dip (10.10.150.24)"
Since the machines are still in the same room (we have 2 phone lines to
test)
I can see both ends:
The TD light on the alpha blinks (while the ping is attempting) and the
RD
blinks on the linux end. However when the ping on the linux end trying
to
ping the alpha, I don't see any TD light going. My feeling is the
problem
is on the linux end, however I'm not sure...I was looking at a sample
dip
login script and it talks about logging into the remote system (which
would
be the alpha system).
If I didn't need to login when hardwired, would'nt that not hold true
now
that modems are involved?
Now a question..These are 33k modems, but I'm setting the SLIP speed to
be
19200, could this be causing my problems?
Thanks. any insight would be helpful.
Currently SLIP is the only option available to me to hook these
machines. PPP
is not an option presently.
