What steps will reproduce the problem? 1. Install from source svn revision 9 2. Install nxclient and nxnode (latest) 3. Try to connect

What is the expected output? What do you see instead?

I expect no errors, but the following error appears in syslog:

What version of the product are you using? On what operating system? ubuntu 9.04 x86-64

Please provide any additional information below. I fixed this by changing File "/usr/lib/python2.6/dist-packages/neatx/utils.py", line 820 to value = 13

Try adding ":" to constants.NXAGENT_VERSION_SEP: NXAGENT_VERSION_SEP = ".-~:"

If this doesn't help, what's the output of constants.NXAGENT_VERSION_COMMAND (the command is most likely “dpkg-query -W --showformat='${Version}' nxagent”)?

Have the same problema, edited /usr/lib/python2.6/dist-packages/neatx/constants.py and back work! :-)

Anyone can commit this change !?

Ah. I see the issue:

dpkg-query -W --showformat='${Version}' nxagent

1:3.3.0-6-0ubuntu1~hardy1

It looks like that version detection really is just too fragile

The fix is to manually set the nx protocol version (e.g. 3.3.0) in neatx.conf:

[global] nx-protocol-version = 3.3.0

this one does not help: [global] nx-protocol-version = 3.3.0

still got the error. The hack for me was to change the command from

dpkg-query -W --showformat='${Version}' nxagent to echo 3.3.0 :)

Hey, I committed a fix to make the nx-protocol-version config entry be parsed properly, i'm wondering if it means you don't need to do the "echo 3.3.0" thing. If you get a chance to test, let me know. Thanks.

In constants.py, why not detect nx version the same way that freenx does? It would be more generic than finding the correct line for dpkg, rpm, pacman, equery (in my case). Something like this works fine here: NXAGENT_VERSION_COMMAND = ("strings %s|grep 'NXAGENT - Version' | sed -e 's/[^0-9.]*//'" % NXAGENT_PKGNAME)

The reason we haven't done that is because it's horrible -)

Hi, I also use a current check-out on Ubuntu.

dpkg-query -W --showformat='${Version}' nxagent 1:3.3.0-6-0ubuntu1

and it doesn’t work

Yeah, basically the auto-version-detection is badly broken. The best thing to do (and hence it's in the INSTALL file) is to manually set the nx protocol version in neatx.conf.

Oops, actually INSTALL doesn't say that, what i did instead was make the example conf contain the correct setting. I've just sent a patch to remove the automatic version detection, which should fix this permanently.

Patch committed. The protocol version now defaults to 3.3.0 (see lib/constants.py), and is overridable via neatx.conf

Hi, this traceback is still present on Fedora 11 although all places that mention protocol version have the same value. nx package is nxagent for fedora. I'm using svn revision 40.

rpm -q nx

nx-3.3.0-35.fc11.i586

grep protocol /etc/neatx.conf

nx-protocol-version = 3.3.0

grep protocol -i /usr/lib/python2.6/site-packages/neatx/constants.py

PROTOCOL_VERSION_DIGITS = [2, 2, 4] DEFAULT_NX_PROTOCOL_VERSION = "3.3.0"

Also in lib/constants.py: NXAGENT_PKGNAME = "nxagent"

This should be only "nx" for Fedora if it matters.

My traceback is:
