dpkg and setuid programs

2000-04-27 Thread Joe
Hello all, When installing programs with dpkg (and it's various frontends) you get no warning when a setuid or setgid file is installed. I would consider it desirable behaviour of dpkg to alert the user who's installing the package that it contains a setuid or setgid binary, the path of that bina

Tollef, NFS requires an RPC portmapper, so things get a bit complicated... SMB over SSH could work though, since it's just a TCP connection to port 139. Simple enough. What's SFS? Regards, Alex. --- PGP/GPG Fingerprint: EFD1 AC6C 7ED5 E453 C367 AC7A B474 16E0 758D 7ED9 -BEGIN GEEK COD

Ethan, The securelevel is obsolete, which is probably why it doesn't seem to be there anymore. Check out the 'lcap' package: once you remove one of the capabilities in that list, it cannot be restored until the machine is rebooted, and you'd probably have to boot into single user mode in order for
