Compress isn`t suid so it gives us no benefit. And here`s my question:
Is there any way to force the ftpd to 'compress' a file before sending it, 
from the client`s side. I`m asking for this particular daemon because of
this: 

[hyph@port ~]$ ls -l /var/ftp/bin/ 
razem 400k
-r--------    1 root     root          313 sie  2  2001 bin.md5
-rwxr-xr-x    2 root     root          16k gru 12  2000 compress <-- :-))
-rw-------    1 root     root         848k mar  3 10:07 core
-rwxr-xr-x    2 root     root          48k sie  8  2000 cpio
-rwxr-xr-x    4 root     root          49k lut  8  2001 gzip
-rwxrwx--x    2 root     root          45k mar 14  2001 ls
-rwxr-xr-x    2 root     root         147k mar  6  2001 tar

The benefits would be obvious.

Sorry if it`s a known bug/vulnerability (but I`ve never heared `bout it before)
