Hello there I have a dial up connection that I am troubleshooting. I have
two DU 4.0d boxes that dials into a modem and the connection is working
properly. Here is an ifconfig of boxa after the connect script is run:
ppp0: flags=51<UP,POINTOPOINT,RUNNING>
inet 10.110.3.9 --> 192.168.1.1 netmask ffffff00 ipmtu 1500
Here is the connect script:
pppd -d user username /dev/tty01 19200 connect 'chat -v "" atdt5551234
CONNECT "\c"' defaultroute
Boxa works fine. I can telnet to another box on the other side, no problem.
I have the same connect script on another computer, same OS.
Here is the ifconfig of boxb:
ppp0: flags=51<UP,POINTOPOINT,RUNNING>
inet 10.110.3.9 --> 192.168.1.1 netmask ff000000 ipmtu 1500
The netmask is different. I don't think that this is a problem, however, I
did use the netmask flag to set it to 255.255.255.0 and still I could not
connect to a computer on the other side of the modem. Why would the netmask
be different with the same script and same dial-in source? Also there is a
line that shows up in the ppp-log file that is different:
default route ioctl(SIOCADDRT): File exists
This line does not show up in boxa, but does in boxb, the one that does not
work. Why doesn't the defaultroute option add a route? It does on boxa. I
guess it is because of this line, but what 'File' exists? I did a:
traceroute 129.168.1.19
traceroute to 192.168.1.19 (192.168.1.19), 30 hops max, 40 byte
packets
1 10.110.0.1 (10.110.0.1) 5 ms 3 ms 4 ms
2 192.168.2.29 (192.168.2.29) 51 ms 43 ms 35 ms
3 192.168.35.10 (192.168.35.10) 123 ms 101 ms 122 ms
So, obviously it is trying to reach 192.168.1.19 through its default gateway
and not through the ppp interface with the same network. If I do:
route add -host 192.168.1.19 192.168.1.1
I can telnet, ping etc. but shouldn't this be covered by the defaultroute
option on my connect script? This is going to be an automated dialup
operation that will be on many boxes so I want to know why it works on one
and not the other. I don't want to have to make up different work arounds
for every box.
Thanks,
