Hi,
With reference to my previous mail:
1. I use openssh-2.9p2 on a LynxOS i386 system. The
ssh and scp clients work fine. Even sftp from other
Linux systems works. But, if I run the sftp client in
LynxOS to localhost (LynxOS) or remote sshd in Linux,
the authentication succeeds, prints sftp> prompt and
then exits. I don't know why this happens. The problem
is with the sftp client program in LynxOS. Does it
work for anyone (sftp client program in LynxOS)?
2. Does anyone use ssh client with seteuid to root?
and it still works? or is there a problem with LynxOS
that seteuid() doesn't work with _POSIX_SAVED_IDS?
3. One more problem. sshd run on LynxOS and ssh
client from Linux system. ssh client hangs on exit.
$ssh hari at lynx (From Linux)
password:
lynx>...
lynx>exit
hangs ......
I don't think it is the regular hang-on-exit bug,
because there are no background processes running, I
suppose, and I get this hang 90% of time. Ofcourse,
lynx> exit > /dev/null < /dev/null 2>&1
makes it clean, but I want to make sure why this
happens. Do you have this problem in your LynxOS
installation?
4. The TERM environment variable remains xterm.
$echo $TERM
xterm
$ssh hari at lynx (From Linux)
Password:
lynx>echo $TERM
xterm
lynx>
How to set TERM to vt100at on login.
I hope you do not have problem here!
5. Addon: In LynxOS, sshd writes to utmp and wtmp on
login, but does not remove entries from utmp on
logout. So, lynx> who
displays the user even after logout. Interestingly,
the size of utmp and wtmp files change (increase)
after login and logout, i.e., the server writes to
them. Then, is it the way the OS interprets it
different, though the sshd server does its job
perfect. Normal telnet programs to Lynx system do not
alter the size of the utmp file.
NOTE: " One strange issue. I compiled openssh-2.9p2 on
Redhat 7.0 Linux system. When the compiled server is
used and when I call ssh, prompts for password and
even if I give correct password, says incorrect
password. " - This has been solved thanks to Ben.
Can I expect some help from someone,
Hari.

If you want a different $TERM, set it manually.> 5. Addon: In LynxOS, sshd writes to utmp and wtmp on > login, but does not remove entries from utmp on > logout.

This is one of the areas of greatest platform incompatability. -d -- | Damien Miller <djm at mindrot.org> \ ``E-mail attachments are the poor man's | http://www.mindrot.org / distributed filesystem'' - Dan Geer
