[BlueOnyx:24971] CentOS8 / Blueonyx 5210R / issues with jailed rsync

[Dirk Estenfeld]

Hello,



today a customer reported that rsync in his CentOS8/5210R jailed enviromnent ist not longer runinng:



[stackrr at orbital7 /]$ rsync

rsync: error while loading shared libraries: libpopt.so.0: cannot open shared object file: No such file or directory



I did a locate for libpopt.so.0 and did see that it should be present in every local lib64 directory:



[...]

/home/.sites/site3/usr/lib64/libpopt.so.0.0.0

/home/.sites/site30/home/usr/lib64/libpopt.so.0

/home/.sites/site43/usr/lib64/libpopt.so.0.0.0

[...]



However it is not:



ls -l /home/.sites/site30/home/usr/lib64/libpopt.so.0 /home/.sites/site35/usr/lib64/libpopt.so.0.0.0 /home/.sites/site4/home/usr/lib64/libpopt.so.0 /home/.sites/site43/home/usr/lib64/libpopt.so.0

ls: cannot access '/home/.sites/site30/home/usr/lib64/libpopt.so.0': No such file or directory

ls: cannot access '/home/.sites/site35/usr/lib64/libpopt.so.0.0.0': No such file or directory

ls: cannot access '/home/.sites/site4/home/usr/lib64/libpopt.so.0': No such file or directory

ls: cannot access '/home/.sites/site43/home/usr/lib64/libpopt.so.0': No such file or directory



alternatively:

ls -l /home/.sites/site30/home/usr/lib64/libpopt.* /home/.sites/site35/usr/lib64/libpopt.* /home/.sites/site4/home/usr/lib64/libpopt.* /home/.sites/site43/home/usr/lib64/libpopt.*

ls: cannot access '/home/.sites/site30/home/usr/lib64/libpopt.*': No such file or directory

ls: cannot access '/home/.sites/site35/usr/lib64/libpopt.*': No such file or directory

ls: cannot access '/home/.sites/site4/home/usr/lib64/libpopt.*': No such file or directory

ls: cannot access '/home/.sites/site43/home/usr/lib64/libpopt.*': No such file or directory



For a site where the client actively uses rsync, I have now done the following workaround:



cp /usr/lib64/libpopt.so.0.0.1 /home/.sites/site37/usr/lib64/

cd /home/.sites/site37/usr/lib64/

ln -s libpopt.so.0.0.1 libpopt.so.0



ls -l | grep pop

lrwxrwxrwx 1 root root      16 Jun 17 18:07 libpopt.so.0 -> libpopt.so.0.0.1

-rwxr-xr-x 1 root root   54688 Jun 17 18:07 libpopt.so.0.0.1



Now rsync is running again.



Now the question is why are the libpopt.so.0.0.0 files not longer in the site<nr>/usr/lib64 directorys and why is in in /usr/lib64 libpopt.so.0.0.1 now and not longer libpopt.so.0.0.0?



@Michael Stauber<mailto:mstauber at solarspeed.net> - maybe you can do some research and find a permanent fix fort hat?



Best regards,

Dirk
