nxclient doesn't work with uclibc or Xorg (system) problem.

    Hi,
    I'm having hard time with linuxterminalserver-1.5.0-client-r21. I'm trying to compile custom system using Gentoo's Portage ebuilds. All I do is standard procedure of Gentoo installation now, except I base my system on uclibc. I even drop kdrive and I'm testing full blown Xorg. Gentoo ebuild incorporates two patches: nxcomp-1.5.0-gcc4.patch nxcomp-1.5.0-pic.patch.

    So: I have uclibc, shell, some useful tools, initscripts, full Xorg, icewm for testing, xterm, screen and nxclient-2xterminalserver.

    All goes right but my nxclient doesn't work. I already tried recompiling it in various ways (different qt, openssl etc) but nothing helped. It appears that during execution of serial steps during protocol initialization the client dies because he sees no confirmation from server that this is the end of one-time information. It goes like this:

    I connect for a first time (here is runlog):

    OK, I understand it failed waiting for the server to confirm its message, what can be found here (sshlog):

    NX> 203 NXSSH running with pid: 2112
    NX> 285 Enabling check on switch command
    NX> 285 Enabling skip of SSH config files
    NX> 200 Connected to address: 83.19.67.237 on port: 22
    NX> 211 The authenticity of host '83.19.67.237 (83.19.67.237)' can't be established.
    RSA key fingerprint is d9:de:ed:3b:4f:80:6e:65:8f:91:f2:b5:aa:89:89:5e.
    Are you sure you want to continue connecting (yes/no)?

    Ooops, but server (nxserver-freenx) did send the confirmation (I don't know it, I suspect that it did as the client works on "normal" ;-) Gentoo perfectly). OK, I can always add this key manually as this is just plain ssh auth path. So when I did, I tried again:

    Hmm, apparently the communication timed out because of some stuck in protocol. There is exactly one minute lag between action and failure, so I assume this is programmed timeout. Well, this says not much more:

    (sshlog-second)

    NX> 203 NXSSH running with pid: 2125
    NX> 285 Enabling check on switch command
    NX> 285 Enabling skip of SSH config files

    HELLO NXSERVER - Version 2.1.0-72 OS (GPL, using backend: 3.2.0)
    NX> 105 Killed by signal 15.


    Any idea guys what is wrong? am I doing some obvious mistake? I got much more things to check yet (for example to compile the same setup using full glibc, omg, it will be few hours more), but maybe some of you got hints now?

    I got also suspicion that this is my window manager who doesn't pop window with question about key acceptance and later on about some other things, but 1. I don't know about what the client is to ask when there is no screen to resume, 2... got lost...

    Bit frustrating, isn't it? ;-)

    Thank you.

    Janusz.
