[opensuse] Headless server
Hi, I'm trying to recycle an old machine as a headless server alongside my main desktop machine. The two machines will be linked through my ADSL router. I have done a standard openSUSE + KDE4.1 install on it, but now need to get it able to run in headless mode. I have set the BIOS to 'Halt on none', so hopefully it will boot without mouse, keyboard or monitor. I now need to set it to boot into runlevel 3, as there is no need for a GUI, but I am not sure which file(s) need editing. My user was set to 'Automatic login' at installation. Hopefully, I will then be able to ssh into my user, having put my id_dsa.pub key into ~/.ssh and into ~/.ssh/authorized_keys I'd be very grateful for any advice or a pointer to a How-To document.

Bob, You can specify the port number to connect to on the ssh command line using the -p switch.

Yep - that'll do it.
Because of setting my internet facing machine's port number to a non-standard one, I do have to specify port 22 for this particular connection, but I've added
Host hostname Port 22
to ~/.ssh/config
so now I don't have to remember to specify it each time. In your case, you would add
Host remoteserver.domain Port <portnum>
and then you could login to his machine with
ssh user@remoteserver.domain
Good tip - I hadn't thought of that. He actually has multiple devices at the same hostname though, with different nat ports to access them externally (they don't have unique publicly accessible hostnames, so I use different ports to access for example his desktop machine (for maintenance and support), his NAS box or his DSL modem/router. What's really cool is that he's actually really liking openSUSE (he's still on 10.3/KDE3 as his machine probably isn't quite grunty enough for 11.2/KDE4) in preference to Vista on his laptop. He told me he actually prefers to use the desktop running linux for most things and he really wants to get Vista off his laptop :-). Chalk up another one for Linux (but all this is getting OT for this discussion...). -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au =================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi Bob, Maybe I didn't understand something, but if you don't need a graphical GUI then you don't need to install KDE or anything alike, I (personal opinion) would even recommend not to install it at all (or now deinstall it). Then your runlevel "problem" will not even appear. Don't know if it's necessary to set the BIOS to 'Halt on none'. Mi PC just gives some beeps at start-up (that says: I have no keyboard) but then starts anyway... Also I guess there's no need to log-in to a user after booting up. Just leave it at the system prompt. Thru ssh you can then always log-in to any user (or root). Again: my opinion, might be wrong... - but I have set up a server here (SuSE 9.0) without keyboard, mouse, monitor. I start it pushing the power button and shut it down after logging in as root via ssh. regards Daniel -- Daniel Bauer photographer Basel Barcelona professional photography: http://www.daniel-bauer.com erotic art photos: http://www.bauer-nudes.com Madagascar special: http://www.fotograf-basel.ch/madagascar/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

If you install the GUI stuff, you can log in remotely and run the GUI on a remote system (e.g., via vnc). Otherwise you cannot. Installing it leaves the option open.

If there is no keyboard, it is common for the computer not to boot. The BIOS often must be told that this is okay and to continue. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

And costs absolutely nothing. You do not even need to run X; just ssh -X {servername} and you can run the GUI utilities to your local display.

I have also installed freeNX on headless machines and then can use the NX client on any machine even a Windows client to get a full working login from anywhere connected to the internet. DC

One of the reasons one might install X and a DE on a headless server is to be able to run X/KDE apps using X forwarding - or to use a VNC-based X server. Some prefer to do that for administration.

On Friday 06 November 2009 07:27:11 and regarding:
Hi,
I'm trying to recycle an old machine as a headless server alongside my main desktop machine. The two machines will be linked through my ADSL router. I have done a standard openSUSE + KDE4.1 install on it, but now need to get it able to run in headless mode.
I have set the BIOS to 'Halt on none', so hopefully it will boot without mouse, keyboard or monitor.
I now need to set it to boot into runlevel 3, as there is no need for a GUI, but I am not sure which file(s) need editing.
My user was set to 'Automatic login' at installation.
Hopefully, I will then be able to ssh into my user, having put my id_dsa.pub key into ~/.ssh and into ~/.ssh/authorized_keys
I'd be very grateful for any advice or a pointer to a How-To document.
TIA
Bob
Bob, Sorry for the late reply. I run about 5 headless servers and there really is nothing to it. Just get the box configured so that it boot reliably and pull the monitor off of it. Over the past 7-8 years, I have only had a handful of occasions where I actually had to plug a monitor back in (aside from upgrading the system). It is very rare that an online update or update from OBS will leave you unable to boot. The number 1 problem that catches people is forgetting to open a port for ssh in their firewall, or changing the ssh port and not updating the firewall. In those cases, since you desktop is right along side, just plug the monitor in and all will be well. If you have suse on both boxes, the don't forget you can use "ssh -X yourheadlessbox" and then "su" and "yast2" to run the gui yast from the other box. In fact you can run all X/KDE apps on the headless box in the same way. If your headless box isn't suse, then you may have to edit /etc/pam.d/su and make sure the line: session optional pam_xauth.so is included in the file so your headless box can use pam to authenticate the xsession request/magic/cookies. It wasn't until this year I learned about ssh -X. For seven years I administered all headless boxes in text more. Forwarding X make headless boxes no different than managing your desktop.
