"Network is unreachable" with new SLIP

"Network is unreachable" with new SLIP

Post by Dennis Direct » Thu, 10 Feb 1994 04:46:40



I am trying to upgrade to the new kernel of Linux (99.14)
so the networking through SLIP will allow my to use
Mosaic.  Everyting but Mosaic works with my SLIP setup
for version 99.13.

I have installed a new system and the new Net-2 packages
according to the FAQs and HOWTOs and READMEs.

I can make a SLIP connection now, and I can ping the SLIP
server after the connectin is made.  Such as:

PING elvex (129.105.9.1): 56 data bytes
64 bytes from 129.105.9.1: icmp_seq=0 ttl=182 time=286 ms
64 bytes from 129.105.9.1: icmp_seq=1 ttl=183 time=257 ms

But when I try to ping any other machine that I normally
connet to I get something like:

PING cauchy (129.105.81.17): 56 data bytes
ping: packet too short (36 bytes) from 129.105.81.17
ping: sendto: Network is unreachable
ping: wrote cauchy 64 chars, ret=-1
ping: packet too short (36 bytes) from 129.105.81.17
ping: sendto: Network is unreachable

I have issued a route command like:

route add default gw 129.105.9.1

as suggested by some previous notes.

Is there a usefull step by step procedure to determine why
I get the dreaded "Network is unreachable ..."?

As usuall, thanks for everyones generous help!

In order to fix this problem, we need the following things:

   - the output of "netstat -n -r"
   - the address you're trying to get to
   - the error message (e.g. "network is unreachable")
   - all commands you're using to configure your network

Doing "route add default..." should have been enough, but that assumes
that the routing table was valid before you issued the command.  If
you're using the newest route, a variant of the route add command that
won't depend upon the previous state of the table as much is

  route add default dev sl0

(where sl0 should be the name of the network device you're trying
to use).

 
 
 

1. SMAIL problems: "lock failed", and "network is unreachable."

        Well, I got smail working so that it went through and delivered
all of the mail that wasn't delivered the last two months. Now I can't
send new mail to anyone. Here's a brief segment of what was in
/usr/spool/smail/logfile:



10/12/94 12:42:04: [m0qv6ke-0004mgC] received
|            from: mark
|         program: sendmail

|            size: 631 bytes

10/12/94 12:45:56: pid 253: new config files, exec(/usr/lib/sendmail)

10/12/94 13:30:58: open_spool: /var/spool/smail/input/0qv6ke-0004mgC: lock failed: File exists

        I don't know if that help anyone or not. I'm running linux
1.1.45, and smail 3.1.28. My system is currently not connected to the
internet, though that shouldn't matter because I'm just trying to send
mail to myself.

        Anyone have any clues, or can point me into a direction to look?
If you need more information, email me.

        Much thanks.
