 sendto: network is unreachable....PPP dialup problems :-(
Hello:

I am running pristine redhat 5.2 out of the box.

-  Using minicom to login to my PPP account over a modem line (there are no
networking cards configured in my system)
-  Using pppd -d -detach /dev/ttyS0 38400 & to startup the daemon

Ping to the IP address of the gateway (same as DNS server) works fine.  All
other pings fail as below.  DNS seems to be working as I can type in names
and they get resolved as shown below:

PING
--------
PING redhat.com (207.175.42.154): 56 data bytes
ping: sendto: Network is unreachable
ping: wrote redhat.com 64 chars, ret = -1

IFCONFIG
--------------
Link encap: Point-to-Point Protocol
inet addr: 205.149.171.120   P-t-P: 204.156.128.1  Mask:  255.255.255.0
UP POINTOPOINT RUNNING MTU = 1500   Metric: 1
........
........

Kernel IP routing table
------------------------------
Destination          Gateway      Genmask      Flags Metric Ref Use Iface
204.156.128.1    0.0.0.0  255.255.255.255     UH  0     0    2      ppp0
127.0.0.0             0.0.0.0  255.0.0.0                   U    0     0    0
lo

Traceroute
---------------
traceroute to redhat.com (207.175.42.154)  30 hops max, 40 byte pkts
traceroute:  sendto:  Network is unreachable
1 traceroute:  wrote redhat.com 40 chars, ret = -1

Notes:
- the net mask reported by IFCONFIG and routing table are different - could
this be the problem, how can I fix it.
- I had not configured networking while installing linux, would this cause a
problem.

Thanks in Advance

Check your /etc/resolv.conf file

It should contain the following:

domain your.isp.domain.name
nameserver ip.address.1
nameserver ip.address.2

This file did not exist on my RedHat 5.2, just make it with vi or whatever.

Hope this helps,
Ken
