Very Computer

I'm currently running Linux 1.2.8 through SLIP on dip3.3.7i-uri and
have problems with talking.  I can receive requests from outside
hosts fine, but I cannot respond to them.  The message I get is (from
talk):

"[Couldn't bind to control socket : Cannot assign requested address (99)]"

and ytalk complains that there is no talk daemon present.  I've checked
the process list when someone is trying to talk to me and there is
a in.talkd process, so I know there shouldn't be a problem starting
up the talk daemon.  I can also talk to myself (talk to someone logged
on to my machine.)  Everything else works fine, telnet, ftp, etc.
I've checked the /etc/services and /etc/inetd.conf and verified that
talk protocols are where they should be.  I've tried other talkd's but
nothing seems to help.

Thanks in advance...

        For some reason, there must be an entry in your /etc/hosts which
directly resolves to your hostname.  On dynamic SLIP/PPP this can be a bit
of a problem, since you then have to do it each time you bring your
connection up, but this can be done with a script.

        For example, my machine's hostname (which really isn't seen by
anyone except me) is "steve".  So I have an /etc/hosts like...

127.0.0.1       loopback
x.x.x.x         steve fqdn

        x.x.x.x is whatever my ip is that time around, and fqdn is whatever
that ip resolves to in the nameserver's DNS tables.

I also get [Waiting for Invitation on caller's machine], [Cannot bind to
control socket (99)], and [No talk daemon on xxx] where xxx is the remote
machine (even though I can talk to that machine from another machine.)
Actually, I've never gotten talk to work even since the 0.xx days of
linux.  I've been able to use talk under windows using WinSock,
so it shouldn't be a problem with the SLIP server.

I checked my /etc/hosts and there is an entry for myself...

Here's a snip:

127.0.0.1       localhost
132.156.64.203  QuickSilver.hip.berkeley.edu QuickSilver quicksilver.hip

We have static IP's here.  My ifconfig for slip is:

sl0       Link encap:VJ Serial Line IP  
          inet addr:136.152.64.203  P-t-P:136.152.64.1  Mask:255.255.0.0
          UP POINTOPOINT RUNNING  MTU:296  Metric:1
          RX packets:1527 errors:0 dropped:0 compressed:1456
          TX packets:2621 errors:0 dropped:0 compressed:2539

p.s. I've also tried a netmask of 255.255.255.0, but same prob.

I also have a problem with talk 'checking invitation on caller's
machine'. My guess it's a routing problem. I have:
        -added to /etc/host
                128.227.16.132  ujj slip1.chem.ufl.edu

        where 128.227.16.132 is the IP address that is given to
me when I have established a PPP connection. 'ujj' is my computer's name.
'slip1.chem.ufl.edu' is name of 128.227.16.132.

        -tried to make a dummy loopback link
                /sbin/ifconfig dummy 128.227.16.132
                /sbin/route add -host 128.227.16.132 dev lo

I still have problems with talk. I probably screwed up with the above.
Here's my route table and ifconfig:

ujj:~# route
Kernel routing table

          RX packets:4296 errors:0 dropped:0 overruns:0
          TX packets:4694 errors:0 dropped:0 overruns:0

128.227.16.141 is the IP for server.chem.ufl.edu which is the computer
that I dial onto using PPP.

128.227.16.132 --> 128.227.16.141 --> internet

I can talk properly from 128.227.16.141 (server.chem.ufl.edu) but not
from my home computer (128.227.16.132).

Also, when doing a make config on the kernel (mine is 1.2.4), what do you
answer yes to when configuring network options?

Thanks in advance for any help.
