Dear Netters,
I am having a problem with my xterm becoming unreachable for a short
period during/after it is booted.
Foolishly, I upgraded by libc and kernel on my portable whilst it
was away from the rest of my network, so I am not sure what is causing
the problems I am seeing, though I would guess that the kernel is the
most likely target.
When I boot my X-Term, it gets the boot image as expected, then its config
files and so on, and background picture until it logs the following in
its messages file...
%FILE-I-READ, reading font file: @term14.snf.Z
%NCDTERM-W-INETCONN, Can't initialize network connection
%NCDTERM-I-MISC, Can't connect to host `193.195.36.1'
There are no unusual events logged in the /usr/adm/messages file just
the usual
Apr 30 08:54:08 lorien in.tftpd[146]: connect from mim.dragon-net
and when the link awoke again...
Apr 30 09:06:04 lorien in.telnetd[199]: connect from mim.dragon-net
As you see, one moment it is successfully tftping files, the next, I
cannot contact the X terminal from my linux box, even pings dont come
back. another linux box on the network can see both xterm and linux
server.
After about 5 minutes the connection comes back to life without any
intervention on my part. Aha, thought I, the 5 minute break sounds like
an inetd timeout, but firstly there is nothing logged to either the
screen or syslog, and secondly that would not stop pings.
The kernels are at least 1.3.96 and 1.3.97, I did not have this problem
with 1.3.91.
The 1.3.96 was built with Slackware's gcc 2.7.0 with libc-5.0.9, the running
system has libc-5.3.12 and gcc 2.7.2.
If there are some procedures which anyone wants me to carry out, then
feel free to ask.
Tim.
PS. When my xterm boots, it always kicks diald into calling my ISP. Apart
from being slightly irritating it has always done it. diald-top indicates
that it is waking up my nameserver, which should know all about both the
server and x terminals information. if there is a bind guru out there,
how do I find out what information it is asking for? I assume that tcpdump
still doesn't work on ppp connections?
