Hi all,
I got a problem with my virus scanner recently. (Ok, you can argue about whether it is useful for linux or not.)
The executable file of it is /usr/lib/AntiVir/antivir. When I list it via "ls" it is also there. But if I try to start it ("./antivir" or just "antivir"), the message: "No such file or directory" appears.
This looks quite strange to me, because I didn't change any settings and the program worked fine before. I already tried reinstalling it, but with no success. "fsck" also didn't find any irregularities. Does anybody know, what to do about that?
Thanks.

what is your PATH?
is the file executable?

/usr/bin is mentioned in PATH. In there (/usr/bin) is a softlink named "antivir" to /usr/lib/AntiVir/ (wherein the binary "antivir" is situated.) the binary is executable. and I otherwise didn't change any settings...


/etc/profile:
if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X1
1"
else
PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
fi

what does "which antivir" say?
can you post the output of "ls -l /usr/bin/Antivir/anti*" ?

"which antivir" says: "/usr/bin/antivir"
and "ls -l /usr/lib/AntiVir/" says:

avguard, avupdater are working, but produce error messages. configupdater works without errors. But antivir-gui also stops with "no such file or directory"

And "antivir" stops with the message:
-su: ./antivir: No such file or directory

I'm working on a amd64 machine here and I have installed a 32-bit chroot. But I can't imagine, any possible change of settings for that could effect antivir not to work. Isn't it?

It says "-su:, but nowhere you mentionned you use su to run it. What is the exact command you use?

Is this antivir file a script? (Try "file antivir")
If so, maybe it runs and there is a command inside the script that doesn't work. In any case, try "strace antivir" and look at the error messages.

Sorry, I thought it was not of importance, because both, trying to run it as normal user or as su produces the same error message.

Now again as su, because the files are owned by root:

debian:~# cd /usr/lib/AntiVir/
debian:/usr/lib/AntiVir# file antivir
antivir: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
debian:/usr/lib/AntiVir# strace antivir
strace: exec: No such file or directory
execve("/usr/bin/antivir", ["antivir"], [/* 15 vars */]) = 0
debian:/usr/lib/AntiVir#

Hm, that sounds, as if there could be indeed a problem with 32bit programm in 64-bit debian, isn't it? But initially it worked very well without explicitly changing into the chroot. But thats a hint I will follow soon.
Thank you very much for your kind help, uselpa. I'll post, if I get it working again. thanks again.
bye
