ssh server

Post#1 by wsteven » 22 Aug 2013, 14:43

Hi there, don't know where to put this.

I was wondering if there's anyway of intalling a ssh server on the kiosk release? The goal is to be able to reboot or kill a process without having to walk ;)
I don't know slackware, I read about modules, can someone tell me a bit more about it?
Thanks in advance,
Steven

hard task to accomplish but you could:
- install (or run in vbox) porteus standard edition
- grab openssh package from slackware-14.0 repo and convert to xzm with txz2xzm script
- disable firewall through kiosk wizard
- boot kiosk to text mode (described in Kiosk FAQ)
- check if you can start ssh server (probably you'll have to resolve missing deps)
- if you manage to get it to work then start ssh through /etc/rc.d/rc.local

if you are not experienced linux user then i would give up.

Hey, I created the module using the desktop version. Tested there, was working fine.
I copied libssh and openssh to the module directory before recreating the iso. Now, X isn't starting and can't even log to shell, as if my password changed :%)
Doesn't make sense to me ^^

Ok, ssh server is working now. If interested, here are the modules : http://dl.free.fr/iN5CF7xML

Now I log on with putty and get :

Code: Select all

login as: root
root@192.168.56.102's password:
Server refused to allocate pty
I don't seem to find an answer on how to add ptys, any idea?
Thanks,
Steven

kiosk kernel is compiled without support for virtual terminals (security wise) so you have to use kernel from our 2.1 32bit standard edition.
please copy vmlinuz and 000-kernel.xzm to kiosk ISO and hopefully this will do it.

if you want pxe boot with new kernel then you'll have to replace all drivers in initrdpxe.xz respectively.

once kernel is swapped you have to mount devpts, add this code to rc.local:

Code: Select all

mkdir /dev/pts
mount -o mode=0620,gid=5 -nt devpts devpts /dev/pts
connecting with kiosk through ssh works here so must also for you :)

If i change run level back to 4 on the inittab file, i cannot login with ssh as if the root passwd changed. Any clue on this ?

Just changing run level back to 3 and rebuild w/o doing anything else fix it, i can login again.

Hello again,

It seem to be related to the X server, if i leave it in run level 4 and add

Code: Select all

/etc/rc.d/rc.4 start & > /dev/null
to rc.local, the X server start but from then i cannot login anymore...

I also can login with ssh, launch the cmd above by hand and all works just fine, if i log out from SSH after killing the X server, i cannot login again using ssh or kiosk shell, it says "permission denied".
