hi everybody, i need an advice to this problem. i had ltsp running well on a server having Suse9.3 and after installing ltsp_rmedia, i got the following problem:

/bin/sh: relocation error: /lib/libnss_files.so.2: symbol _nss_files_parse_pwent, version GLIBC_2.0 not defined in file libc.so.6 with link time reference.
