Hello, as I have read manual, if I use in file authorized_keys option command="" with some command, no other commands will be permitted. I have tried it, created authorized_keys2 for root and added there command="rdiff-backup --server" and after that tried to login. Thit command was executed, but I was normally able to supply other comand as root. Can you tell me why? Thank you Martin _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
