I have two SCO openserver systems, 1 in the US and 1 in the UK.
I am setting up a vpn to connect the two local networks that also have windows pc's on them.
Is there a way that either unix system can see the hard drive on the other unix system so that I can share data between them.

I have RedHat 9.0 installed on three of my servers (PIII - 233MHz) and want that they share a common IP address so that any request made reaches each of the servers.

If I use sockets for IPC, and can easily distribute my applications.
UNIX Message Queues are local to the processor.
As I understand it, Message Queues still incur system call overhead, just like socket calls.
What advantage does a UNIX Message Queue provide versus a TCP or UDP Socket,... (2 Replies)
Is there a performance advantage of one of these over the other? Obviously, it makes no sense to use normal TCP sockets or UDP sockets w/ the overhead they carry. But what about UNIX domain sockets vs FIFOs? I'd think they'd be very similar, in terms of performance and in terms of how they're... (2 Replies)
Hi,
i understood that there are several type of sockets: TCP, UDP & Unix.
i wondered, what is the performance advantages of unix socket of the other types?
isn't it equal to use UDP with localhost as destination over unix socket?
Thanks in advance,

MAC_SEEOTHERUIDS(4) BSD Kernel Interfaces Manual MAC_SEEOTHERUIDS(4)NAME
mac_seeotheruids -- simple policy controlling whether users see other users
SYNOPSIS
To compile the policy into your kernel, place the following lines in your kernel configuration file:
options MAC
options MAC_SEEOTHERUIDS
Alternately, to load the module at boot time, place the following line in your kernel configuration file:
options MAC
and in loader.conf(5):
mac_seeotheruids_load="YES"
DESCRIPTION
The mac_seeotheruids policy module, when enabled, denies users to see processes or sockets owned by other users.
To enable mac_seeotheruids, set the sysctl OID security.mac.seeotheruids.enabled to 1. To permit superuser awareness of other credentials by
virtue of privilege, set the sysctl OID security.mac.seeotheruids.suser_privileged to 1.
To allow users to see processes and sockets owned by the same primary group, set the sysctl OID
security.mac.seeotheruids.primarygroup_enabled to 1.
To allow processes with a specific group ID to be exempt from the policy, set the sysctl OID security.mac.seeotheruids.specificgid_enabled to
1, and security.mac.seeotheruids.specificgid to the group ID to be exempted.
Label Format
No labels are defined for mac_seeotheruids.

mac(9)HISTORY
The mac_seeotheruids policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.
AUTHORS
This software was contributed to the FreeBSD Project by Network Associates Labs, the Security Research Division of Network Associates Inc.
under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.
BUGS
See mac(9) concerning appropriateness for production use. The TrustedBSD MAC Framework is considered experimental in FreeBSD.
While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by
entry point checks. As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user.
