Try setting that first, then FTP. Umask doesn't set any bits not already set. Also, FTP may not source /etc/profile, first -- I don't remember. Consider using scp (or sftp). You first need to: 1) cd /etc/pam.d 2) sudo vi sshd ==> session optional pam_umask.so umask=0002 3) sudo vi login ==> session optional pam_umask.so umask=0002 TAR files are another problem. The group-write bit must first be set. <snip> _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
