Hi....
Can anyone point to documentation or tell me if the non-console pseudo terminal device "permissions" HAVE to be set to be world readable and/or writable? I cannot find any documentation on this. Thanks in advance.

Re: Non pseudo devices being world writeable and world readable
Demat Janice,
It seems to be normal, I've looked on a new server and they are owned by root root and with rights to 0666.
hope this helps

Good judgement comes with experience. Unfortunately, the experience usually comes from bad judgement.

Unused pty's are set to 666 since any incoming user needs access. Once a daemon (like telnetd or sshd) is attached to a pty, the permissions are usually changed. World readable and writable for an unused pty is fine as it points to nothing so sending or reading data to these device files does nothing. Once the device file is in use, it is protected.
