TL 4.19 and TL 4.18

ThinLinc
1

I’ve installed tl 4.19 as a master and have several 4.18 agents.

after installing, the master cannot connect to to agent(s). on the agent i see:

DEBUG vsmagent: Handling method ‘ping’ from (‘x.x.x.x’, 1022)
DEBUG vsmagent: Unknown method ‘ping’ from (‘x.x.x.x’, 1022)

after upgrading the agent to 4.19 the master can connect and in the logs i see:

DEBUG vsmagent: Handling method ‘ping’ from (‘x.x.x.x’, 1023)

(while when master and agent were 4.18 i saw:

DEBUG vsmagent: Handling method ‘get_load’ from (‘x.x.x.x’, 1023)

)

so are 4.19 and 4.18 incompatible or do i have an configuration problem?

Hi @jean,

4.19 and 4.18 are incompatible I’m afraid, due to protocol changes between the two versions. In general, it is strongly recommended (and in many cases, required) that all servers in a cluster are running the same ThinLinc version.

Hope that helps!
