19.10 + Nomachine nxclient_3.5.0-7_amd64.deb

772

so i'm a long time user of nomachine products. Lately i was (still am) happily using nxclient 3.5 on an ubuntu 18.04 to connect to a nomachine workstation 6.4 server (evaluation version).

Things are working great, minus the required replacement of the included libz.so.1.2.3 that apparently fails in 18.04 and has to be overwritten with the system version.

However, doing the same on a ubuntu 19.10 (and 20.04) doesn't work anymore, and the client appears to hang during connection with this sshlog:

NX> 203 NXSSH running with pid: 7507
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files

NX> 208 Using auth method: publickey
HELLO NXSERVER - Version 6.4.6 - NoMachine Workstation Evaluation
NX> 105 NX> 280 Exiting on signal: 15

to compare with the same package ran on 18.04, here's the sshlog from the other machine:

I don't fully understand what could be the reason for nxssh hanging after the server has replied, since the installed package and binaries are the same.. Any suggestions?

ps: the reason i'm asking about nxclient 3.5 is because i already tried to use the latest client, but it somehow sucks much harder when using the "light" protocol (= old nx protocol) compared to the 3.5 client, and that's why i'd like to stick to it.

and the runlog from the 18.04 installation (IP is different in this specific run, but it's the same machine. Have working runlogs also for remote connections), at http://paste.debian.net/hidden/7b6fcd46/ (due to message limits here on SE)

Same problem has occurred to me when I upgrade from 18.04 to 20.04 some days ago. After long search on WEB I found there is a Remmina NX plugin, you can install it through apt.

It works well, also I can hear sounds from server.

I hope this can help you.
