[SOLVED] FREENX - using twm

[nl-x]

Hi all,

Since a recent topic I have FreeNX running. Previously I wasn't able to log in. But that appeared to be a SELinux issue.
Now that is solved, I can connect with FreeNX. But still, I dont get a screen yet.

The point is, I don't have Gnome installed. I want to have a most-basic version of Gnome and asked how to install it.
Scottro advised me to use TWM.

[quote]What if you don't use Gnome. There's a few different ways to do a minimal X install.

The simplest may be

yum install xorg-x11-* xinit xterm


That brings in what seems like a lot extra, but is only 10 MB or so in size--save the 8-9 MB is possibly more work than you feel like doing.

Then, in the FreeNX client, you'll want to Desktop Unix Custom, and use /usr/bin/twm as the command. Also, uncheck the default floating window and choose new virtual desktop.[/quote]

First of all i need to say that [b]yum install xinit[/b] failed, as no such packet is available. (xorg-x11-* and xterm installed successfully)

Secondly, I configured the FreeNX client to use /usr/bin/twm (and I checked first to see if it exists), and configured it to use New Virtual Desktop in stead of Floating WIndow, ... but I could not open a window. I got the following "Connection Error" message:

You might also want to try: ssh -X myserver; /usr/bin/nxnode --agent to test the basic functionality. Session log follows:

[/quote]

FYI. Please note that my SSH runs on port 22. But I have a NAT router that forwards port 2021 to port 22 on this server. (In my previous installation (CentOS 5.6 - Gnome) this worked well.)

As far as I can see, user 'nx' now can log in. And even the second user 'root' manages to log in. But the TWM does not open.

Any help is appreciated.


Kind regards,

Hmm. Ok, I have already solved this one...
Before I had disabled encryption on all traffic, in the time I didn't know that SELinux was bothering me.
Apparently disabling all encryption is not allowed.

Next (and hopefully last) question:

OK. NX is working. TWM is working.
Now , how do I open Pirut !? (The Add/remove software application)

If Pirut has been discontinued on CentOS6, then what is its replacement called?


[b]EDIT:[/b] According to http://rpm.pbone.net/index.php3/stat/4/idpl/16612205/dir/centos_6/com/gnome-packagekit-2.28.3-3.el6.i686.rpm.html , gnome-packagekit should provide pirut. But I have it installed, and there is no pirut provided.

The new question is OT, and it looks like you figured out the add/remove software question in your [url=https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32365&forum=55&post_id=138529#forumpost138529]other topic[/url] anyway, so I am marking this one [SOLVED] for posterity.
