Re: SLES 11 and FreeNX (libpng.so.3 missing)

SUSE Linux Enterprise Server SLES Configure-Administer

Is there a concise solution to getting FreeNX to work on SLES 11 SP1
64-bit? I just did a default install of SLES 11 SP1 64-bit and the
latest NX Client, Node, and Server from the NoMachine website, but I
can’t get connected from a remote client. I see the talk about adding
libpng.so.3 but don’t really know which package I need and how to
install it. I’m not even sure that is the problem and I can’t get any
additional info from messages:

Hi
I only have a 32bit machine SLES 11 SP1 with NX, I’m assuming you can
ssh onto the machine as your user name?

It looks like it may not like the host name C-lx04? Can you set a
hostname without the - to test?

Yes, I can ssh to the machine with the same username just fine. The
hostname is just lx04:

Code:

Hi
OK, if you ssh onto the machine and move the .nx directory
[/CODE]
mv .nx .old_nx
[/CODE]
Now, I’m guessing your using KDE as the desktop? If it’s gnome then
check you have gnome set as the desktop in the NX client.

I have both KDE and Gnome installed on the machine, have logged into
both from the console, and have tried both settings in NX Client with
the same result. I have also tried the 32-bit NX packages, and
installing the 64-bit packages from rpm as well as tar. Same result.
In thinking about your previous post, I set the hostname during install
and unchecked “Change hostname via DHCP”. Nothing is set in /etc/hosts
except for 127.0.0.1 localhost (maybe there should be a line for lx04,
it’s IP, and the University LAN assigned long hostname). We have other
openSUSE boxes that are configured the same (I think) that work. None
the less, it does give me something to look at tomorrow to make sure.

Hi
Yes, set the hostname in YaST and uncheck the box so it doesn’t change.

Hi!
Have NX also on 32bit SLES 11 SP1, does work ok. Have You tried
TightVNC? Yes, it is not NX.

Unfortunately the end user of this machine has a very difficult time
adjusting to even a minor change in anything computer related. I am
actually amazed at how he spends 60+ hours per week writing, compiling,
and running code, and yet when I asked him what compiler he uses, he
didn’t know. Could you imagine driving a truck for a living for 60+
hours per week and not knowing what kind of truck it is?

Not to mention that NX -should- work.

Hi again!
If I recall correctly TightVNC not require any special installation
from server side (if there isn’t set any special restrictions etc.,
default settings should do), You just need to have general remote access
to server and client soft installed, of course.

Hmmmm, now I’m puzzled. I did essentially the exact same installation
on different hardware and it works. The only differences in the
install were that I added KDE during setup and not after it was up and
running (maybe I missed a package or something??) and that I checked
“Add a hostname for loopback” or whatever it says when setting up the
hostname (Change via DHCP was unchecked). The network card is different
hardware, so maybe that is it. I think I also want to run a check on
the HD in the first computer.

I did an fsck on reboot and nothing was found. I then did a reinstall
but created new partitions of different sizes, installed as I did the
second machine, and everything works. I’m not really sure what the
problem was, but I’m moving on now. Thank you for the help, everyone!
