Hi Folks,

i´ve got some problems running Nexuiz 2.0 in CHROOT-environment. It seems to me, that Nexuiz can´t load libcurl.so.3, so I copied this file to different direcories (/lib, /usr/lib, /nexuiz) inside the CHROOT-environment, but the error still persists.

When i don´t use the CHROOT-environment, that error message doesn´t appaer.

Is there anybody out there running Nexuiz in CHROOT-jail?

Thanks in Advance, tli!
(...my native language is german, please forgive me )

so you do : chroot /opt/games/Nexuiz /bin/bash ? or some other form please ? Also consider installing the correct libs inside the chroot. (If you are doing this for 64/32 bit issues, nexuiz compiles and runs fine in 64bit)

Hi Qantourisc,

in case i don´t understand your answer, here´s my setup:
- added user and group nexuiz to the linux-host
- created directory /home/nexuiz
- created directories bin, etc, home, lib, usr/lib inside /home/nexuiz
- copied resolv.cfg and passwd to /home/nexuiz/etc (stripped down passwd-file to one entry for user nexuiz)
- unzipped nexuiz-20.zip to /home/nexuiz.20 and created symlink to /home/nexuiz/nexuiz (data, Docs, sources, Nexuiz.app, ...)
- did ldd on 32-bit dedicated server binary-file and copied needed libs from host to /home/nexuiz/lib
- also copied some binarys (su, bash, cp) to /home/nexuiz/bin
- tried to start nexuiz ded. server
(error message: Trying to load library... "libcurl.so.3" "./libcurl.so.3" - failed.)
- copied libcurl.so.3 to /home/nexuiz/lib and /home/nexuiz/usr/lib
- also copied libcurl.so.3 to /home/nexuiz/nexuiz


BREAK - BREAK - BREAK

While posting i´ve figured out, that some files where still missing. The server seems to work now.

I´ll be back later to post my final answer "How to set up Nexuiz in CHROOT".

Thanks.

I am running the nexuiz server as a regular user and I have the same message alltyhough I'm not sure libcurl is installed though XD

Sorry, i cannot edit my previous post:

My setup is based on this guide setting up an dedicated server for Wolfenstein: Enemy Territory.

That error message concerning libcurl.so.3 still appears, but the server is running fine!

Does anybody (development team) know, where Nexuiz is looking for this lib?

Please visit my server @ feierabendsoldiers.de:26000 (running in public mode from thursday 04:00 am till wednesday 04:00 am (all times GMT+1) and send me your comments @ ICQ 145656139.

I think you do not really need this lib on the server. The client uses libcurl for the content download.. Suppose its an error that the server also needs this lib. After all from what i understand the server just tells the client a url were he can download the stuff.

You could ofcours safe yourself a lot of trouble and just do mount -o bind /lib /home/nexuiz/lib

Just like any other linux app it searches in the paths listed in /etc/ld.so.conf or LD_LIBRARY_PATH. Have you tried

Code: Select all

export  LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/nexuiz/lib"

?

Well, i created the file /etc/ld.so.conf with only one line containing /lib and copied that missing file libcurl.so.3 to /lib of my CHROOT-jail, but the error still persist.

Cause NEXUIZ is running fine, i won´t spend more time on this error message.

Keep fragging!

libcurl also loads other libraries. In my case:

Code: Select all

$ ldd /usr/local/lib/libcurl.so
/usr/local/lib/libcurl.so:
        libidn.so.16 => /usr/local/lib/libidn.so.16 (0x28169000)
        libssl.so.4 => /usr/lib/libssl.so.4 (0x28198000)
        libcrypto.so.4 => /lib/libcrypto.so.4 (0x281c1000)
        libz.so.3 => /lib/libz.so.3 (0x282a2000)
        libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x282b1000)

But if you are talking about chrooting, you probably are referring to a dedicated server. On a dedicated server, the library is only needed for the "curl" console command to work. Content download information is sent by the server in any case, so it shouldn't matter.

I've written a chroot wrapper for a Sauerbraten servers. Look for "sauer-server-jail" on my Sauerbraten page:
http://home.austin.rr.com/selliott4/sauerbraten/
which may be helpful for comparison.

Also, I used "strace" to determine which files were being read and written to. Something like
strace -f -o nexuiz.out -f -e'open,stat' ./nexuiz-linux.sh
might do it.
