Q:s about rsh, X connections and sendmail with ppp

Post by Leif Lonnbla » Tue, 16 Jan 1996 04:00:00

Hi there,

I have now ppp up and running between my Sparcstation 4 running asppp
(Solaris 2.4) at home and my ISP running something called Slirp.

Many things work fine: telnet, ftp, ping, finger, http, rlogin,
etc. But there are a few things that don't, and they are a bit puzzling
to me. Hopefully some of you at there can help me.

rsh: It's funny, rlogin works perfectly, so there is no problem with
my .rhosts files or anything. Rsh just does nothing and returns
quietly with an exit status of 1. Any ideas?

X connections: When starting Slirp on my ISPs side I issue a redirect
command looking like 'redir X' and it gives me a
DISPLAY variable to use on a remote machine. However, on a remote
machine any x application returns with:
XIO:  fatal IO error 32 (Broken pipe) on X server "(null)"
      after 0 requests (0 known processed) with 0 events remaining.
      The connection was probably broken by a server shutdown or KillClient.
I know that xhost is not the problem. I tried to use
snoop but all I could understand is that the remote machine actually
tries to contact my home machine, but for some reason the X server
doesn't respond. Anyone had similar experience?

sendmail: Sending mail works only to local addresses or to machines
present in /etc/hosts. It actually works to some others but I don't
understand when and why. I guess that I need to hack sendmail.cf to
tell sendmail to deal with everything local itself, but send
everything else to the my ISPs mailserver. Unfortunately, it is not
quite trivial to understand how to do this in sendmail.cf. Can anybody

Thanks in advance,

1. RH5.1 PPP connection: PPP connection persists, telnet session times out

Ever since I installed RH 5.1 when I connect to an NT Server modem
port and authenticate with PAP/CHAP the physical line connection stays
up as before (5.0) but any telnet session to Unix machines on the same
network time out on inactivity in predictably 2 minutes and 10
seconds.  Since I had no such problems prior to 5.1 I'm wondering why
this is a different animal.  Also it does not help to ping the same
server on a 10 second interval -- the ping keeps on going but again
any telnet session times out.

Would be glad to supply any additional info.  I realize that this is
pretty sketchy but I'm not sure what sort of info would assist.
