Hello Forum :
My apologies if this sounds like a newbie question. I am attempting to setup our backup servers for developing GUI versions of our character-based programs. I have modified the iptables on the CentOS server to accept tcp port 4093, and I have issued the command /0/pxp15/pxplus "*plus/cs/host" -arg "4093;recon=300" and the server answers back : Awaiting connect ... When I issue the lsof -i:4093 command, it shows the process listening. Both the server and the client machine are on the same node, so no firewall is blocking the attempt, and we are not using SSL.
[root@ecoback ~]# lsof -i:4093
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
pxplus 12481 root 5u IPv4 816627 0t0 TCP *:4093 (LISTEN)
[root@ecoback ~]# iptables -L | grep 4093
ACCEPT tcp -- anywhere anywhere tcp dpt:4093
Then, I attempt to connect from an Ubuntu 16.04 workstation running Wine, from a command window, using :
"/home/prog/.wine/drive_c/PVX Plus Technologies/Windx Plugin 2018 Upd 1/pxplus.exe" *plus/cs/client -arg 192.168.150.6;4093
After a brief pause, the message box comes back stating that it cannot connect to 192.168.150.6 on port 4093, and offers to test
connectivity by browsing th http://192.168.150.6:4093
. That does not connect either, but we have never allowed http traffic into
the backup server. Do I have to specify a startup program? If so, does that program need to be resident on the server, or on the client?
