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 run a cobol... (1 Reply)
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.
Can anyone suggest how should I setup my LAN. I'm new to networking in Linux so please elaborate and would be thankful for a timely... (2 Replies)
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,

Hello,
I am having some trouble using screen sharing with my Mac. There is a Mac Pro in the lab at my school, and I need to access it via screen sharing from my Macbook Pro from home. Each has Lion. The screen sharing works when I am in the lab and the Mac Pro is on the WiFi network, it also works... (1 Reply)

ssh-add
SSH-ADD(1) BSD General Commands Manual SSH-ADD(1)NAME
ssh-add -- adds RSA or DSA identities to the authentication agent
SYNOPSIS
ssh-add [-lLdDxX] [-t life] [file ...]
ssh-add -s reader
ssh-add -e reader
DESCRIPTION
ssh-add adds RSA or DSA identities to the authentication agent, ssh-agent(1). When run without arguments, it adds the files
$HOME/.ssh/id_rsa, $HOME/.ssh/id_dsa and $HOME/.ssh/identity. Alternative file names can be given on the command line. If any file requires
a passphrase, ssh-add asks for the passphrase from the user. The passphrase is read from the user's tty. ssh-add retries the last
passphrase if multiple identity files are given.
The authentication agent must be running and must be an ancestor of the current process for ssh-add to work.
The options are as follows:
-l Lists fingerprints of all identities currently represented by the agent.
-L Lists public key parameters of all identities currently represented by the agent.
-d Instead of adding the identity, removes the identity from the agent.
-D Deletes all identities from the agent.
-x Lock the agent with a password.
-X Unlock the agent.
-t life
Set a maximum lifetime when adding identities to an agent. The lifetime may be specified in seconds or in a time format specified in
sshd(8).
-s reader
Add key in smartcard reader.
-e reader
Remove key in smartcard reader.
FILES
$HOME/.ssh/identity
Contains the protocol version 1 RSA authentication identity of the user.
$HOME/.ssh/id_dsa
Contains the protocol version 2 DSA authentication identity of the user.
$HOME/.ssh/id_rsa
Contains the protocol version 2 RSA authentication identity of the user.
Identity files should not be readable by anyone but the user. Note that ssh-add ignores identity files if they are accessible by others.
ENVIRONMENT
DISPLAY and SSH_ASKPASS
If ssh-add needs a passphrase, it will read the passphrase from the current terminal if it was run from a terminal. If ssh-add does
not have a terminal associated with it but DISPLAY and SSH_ASKPASS are set, it will execute the program specified by SSH_ASKPASS and
open an X11 window to read the passphrase. This is particularly useful when calling ssh-add from a .Xsession or related script.
(Note that on some machines it may be necessary to redirect the input from /dev/null to make this work.)
SSH_AUTH_SOCK
Identifies the path of a unix-domain socket used to communicate with the agent.
DIAGNOSTICS
Exit status is 0 on success, 1 if the specified command fails, and 2 if ssh-add is unable to contact the authentication agent.
