Telnet problem from Windows to stable from July 18th
Has anybody seen (or has any explation for) this ?!
I have a user whos login .profile consists of the line:
exec bin/test.sh
The script "test.sh" looks like this:
#!/bin/sh
echo Choose file 1 or file 2
n=`echo ${n}`
FILE_NAME=""
while test "${FILE_NAME}" = ""
do
FILE_NO=0
echo -n "Choice: "
read n
if test "${n}" = "1"
then
FILE_NAME=file1.txt
fi
if test "${n}" = "2"
then
FILE_NAME=file2.txt
fi
if test "${FILE_NAME}" = ""
then
echo ${n} is not a valid choice - please choose again
fi
done
echo Chosen '"'${FILE_NAME}'"'
sleep 1
exit
(its a similfiled version of the real script- but this demonstartes
the problem simply enough)
The idea is that the uuser logs in and is presented with the menu from
the script. They then choose 1 or 2 to select a file. This has been working
for some time now, and I had almost forgotten it existed until the last
upgrade to track -stable.
What now happens is that if someone telnets to the box (from any
windows telnet client - not just the standard telnet) and logs in
then are presented with a continually scrolling screen of
Choice: is not a valid choice - please choose again
Choice: is not a valid choice - please choose again
Choice: is not a valid choice - please choose again
Choice: is not a valid choice - please choose again
etc...
as if the read from the inoput was always getting a blank string. This
has only just started happeing, and it only happens with windows telnet
clients.
Interestingly, if I alter the .profile to
bin/test.sh
exit
then the script functions fine. Does anyone have any ideas ? As both
the standartd windows telnet and the commercial terminal application
"reflections" behave the same then I amwondering if the problem is some
incompatibility with the windows tcp/ip stack maybe ?
I;d apperciate it if someone elsecould verify that it does the same on their
machine too...
cheers,
-pcf.

Your culprit is most likely the > Firewall-1 machine. Well, it would be nice to blame FW-1 on this, but I can't. I can open 2 windows from my Sun thru the firewall to the FreeBSD machine. With the first one, I do my normal things, working on the machine, with the second I telnet out. The first one never dies. I can have one window open all week long. The second one dies after an hour of idle time. The same thing will happen if I telnet (TeraTerm) from my Win2000 machine to the FreeBSD machine, that are on the same network. The same thing will happen if I telnet to the Win2000 machine. The only constant in all my synario's is the telnet client program on FreeBSD. -- This looks like a job for legal tender! - The Tick To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
