Does the Linux version of Livius actually work?

[dejan]

Could anyone here who uses Linux build of Livius confirm being able to connect to the GrahamCCRL.dyndns.org ?
I have tried 50 times to connect to this server in the last few months, and it failed every time (I double-checked the connection parameters - I am perfectly aware of the fact that port changes all the time).

It works fine here. (I use fedora 30 and compiled the source from github in april 2019, the 5th). Tom's live chess viewer also used to work with wine.

Hey Richard - glad to see you here!
Look, could you please do a

Code: Select all

telnet GrahamCCRL.dyndns.org 16001

and tell me whether it gives any output?
When I execute it all I get is:

Code: Select all

dejan@turing$ telnet GrahamCCRL.dyndns.org 16001
Trying 222.154.252.101...

After some time the connection times out.

I also use Fedora 30 and latest Livius...
Is it possible that I always picked the time to connect when the server was down??

I can confirm that Livius works fine under Linux (Xubuntu 19.04 here) compiled from source.
The telnet test doesn't work cause it tests tcp connection while TLCV / Livius uses udp protocol.

telnet does not work for me either, but livius does. A quick look at Livius code shows that it communicates through UDP, while telnet uses TCP/IP, so I guess this result is not surprising:
Using nc to test the connection through TCP, I get:

Code: Select all

$ nc -zv GrahamCCRL.dyndns.org 16001
Ncat: Version 7.70 ( https://nmap.org/ncat )
Ncat: Connection timed out.

and UDP:

Code: Select all

$ nc -uzv GrahamCCRL.dyndns.org 16001
Ncat: Version 7.70 ( https://nmap.org/ncat )
Ncat: Connected to 222.154.252.101:16001.
Ncat: UDP packet sent successfully
Ncat: 1 bytes sent, 0 bytes received in 2.02 seconds.

Thanks Richard - I did not know it uses UDP... I still can't connect via Livius anyway... Will look further.

[dejan]

Still can't make it work... I give up.

Have you tried REGO?
