Setting up a Linksys WRT54G router for SSH port forwarding
by Mickey
Fedora 12 on both computers
I have two computers setting behind this Linksys WRT54G router and I
want to connect to both of them by SSH remote across the Internet. I
have the internet IP for this router.
#1 192.168.1.100
#2 192.168.1.101
In the The Applications and Gaming Tab - Port Range Forward Tab , I have
setup one computer as , ssh 22 22 Both
192.168.1.100 enable and it works okay.
But how do I setup computer #2 192.168.1.101 .
I have Googled the Internet and found out how to setup one on port 22 ,
but not Two computers using SSH port 22

Oops itself is probably suited for bug report, but what isn't clear for
me is line

Which module caused that kernel is tainted? I suppose Fedora contains
only open SW including kernel modules, isn't then there something wrong?
Thanks, Franta Hanzlík

SSH can't connect
by Mickey
Wether I run NX (nomachine) or SSH I get the same error message, no
matter what host I try to connect to.
And on the host servers SSHd is running.
And so is the Client box.
Running NX
Error message: ssh: connect to host 70.236.39.98 port 22: Connection
timed out
Running $ ssh jim(a)70.236.39.98

a sound problem
by 猫行天下
thank you,Stan,and everyone.
In fact, i uses fedora13.the uname -a returns:
Linux sc.sc 2.6.34.7-56.fc13.i686 #1 SMP Wed Sep 15 03:33:58 UTC 2010 i686 i686
i386 GNU/Linux
the version of Gnome is libgnome-2.30.0-1.fc13.i686
the version of pulseaudio is 0.9.21-6.fc13
er....some thing shamed me...the problem I have described seemd not so
correct,today when i logging in the console(tty),
as usual, the music is off. changed to the gnome,as usual,no change. but then i
logout the console and changes into the gnome,
the music *returns*.so,my question is, how can i change the settings to let the
music played even if i switched into the console(and logged in).
i know the wrong description is wasting our time..so sorry to everyone .
especially Stan.

Kernel errors

I got this error in logwatch this morning:
WARNING: Kernel Errors Present

I don't see any problems with my system. What does it mean? Google
wasn't particularly helpful.

what could "use up" X forwarding connections?
by Tom Horsley
Anyone have any clues about what could "use up" some resource
used to create a forwarded X connection (ssh -X)?
I've got these testbeds that run 24/7 on random collections
of both real and virtual machines, and they are all started
from inside a VNC session using ssh -X to get to the target
test machine. The theory is that any test which needs a X
server will be happy with the VNC server.
After running for a few months, tests sometime start failing
because they can't open the X server. Reboot the host (which
is running fedora 13) and recreate the VNC server and things
work again.
Seems like something is getting "used up" that the reboot
cleans up, but I haven't been able to find out what
that something is :-).

input actions, keyboard input (from program output)
by Dj YB
Hello,
I am trying to achieve the next goal.
when I hit a shortcut like (Ctrl+Alt+T) the output of a certain script will be
written to where the cursor is.
so far I didn't find a way and am doing so using the clipboard.
if anyone know or have an idea that would be great.
Thanks in advance,
YB.
