I'm running C-Kermit 8.0.201 on a Red Hat 8.0 Linux box. I am a bit
puzzled about how I should be setting permissions and ownerships of things
to make life easiest.
I note that /dev/ttyS? (COM1 and internal modem at COM3) are owned by
root, group uucp, mode 660. So, I say to myself, "I'd better make kermit
sgid to group uucp."
Running kermit and doing a "set line /dev/ttyS0", I am told that
Permission is denied on /var/lock, with "Sorry, write access to uucp lock
file directory denied." Sure enough, /var/lock is owner root, group lock,
mode 775.
As far as I know, I can't have kermit be sgid to *both* "uudp" and "lock"
groups, so I get to choose whether I want to access the port or access the
lock for the port. Unfortunately, both are required to allow access to the
port.
I'd like to know what access parameters I should be changing how, in order
to allow kermit to function with my ttyS? ports, without screwing up
anything else I might need to be doing with them. (I have no plans to do
serial UUCP, but might want to establish an outbound PPP session or have
an incoming getty (of some flavor) on either or both ports.) I'd rather
not run kermit suid-root, if that can be avoided.
I'm tempted to install the uucp software, just to see how *it* manages to
access both the port and the lock directory.
I imagine that this is a "solved problem". Anyone? Thanks!
