NJE38 - talking from TK5 update 3 to TK4- with an older version of NJE


 
Edited

Dear Forum,
so far, I have setup the copy of TK4- from my cloud system on the same Pi 5 where the new install of TK5 is running. Now I try to have them talk to each other via NJE38. There is an older (2.2.x I guess) install of NJE38 on the TK4- system and a more recent version (2.5.0) on TK5 update 3. Having set up the config like this:
?
*NOTE: archives on github and here claim NJE38 Version 2.4.2, however, NJE38 identifies itself as 2.5.0 in the syslog on TK5).?
?
Node X484 (TK4-)
094 tcpnje 2703 lnode=X484 rnode=X406 lport=1175 rport=2175 rhost=x406.fritz.box
Node X406 (TK5-)
094 tcpnje 2703 lnode=X406 rnode=X484 lport=2175 rport=1175 rhost=x406.fritz.box
?
The syslog of X406 complains about with the following message to syslog

HHCTN049E 0094:TCPNJE - Attempt to write 455 bytes to output socket only wrote 0 bytes. Error: Bad file descriptor

The Link on the TK5 node is shown "inactive" while the link on TK4- is active.?

Could it be that running the NJE38 hosts on the very same machine is not supported? Or do I need to upgrade the NJE38 on TK4- to the same level??

Nota bene: when issuing /S SHUTDOWN, the NJE38 STC gets purged on the TK4- node but then there is no further progress. TK5- shuts down a whole lot more including VTAM but also does not exit the Hercules emulator.?

Hmm...

Michael,

Two copies on the ONE PI – pretty aggressive – unless you just want to prove you can –

Just get another pi – not expensive – I just picked up another – and just cuz – I can – installed Win 11 – and it does run – slowly – with some limits –

?

Just for fun – I have it in my HOME LAB – and I RDP to it from my main desktop - -

?

Just get another Pi5 – and a NVME hat – and a NVME stick – THEN have the two talk – across a IP network – (I recommend with a wired connection)

?

?

Hi Jeff,?

good news first: got both TK4- and TK5 running on my Pi 5 (8GB) and talking to each other via NJE38 (2.5.0 from Rob Prins' Tk5). I agree with you in general - even the current Pi 5 is another big step forward, it might get loaded easily. However, it's not cheap. My config is
?
Pi 5 8GB (98,- EUR)?
Samsung 980 1 TB SSD (90 EUR)
Sunfounder Pironman 5 housing with all necessary adapters (78 USD)
?
System is Raspberry OS "bookworm" (though I prefer Ubuntu on my Intel NUC)?
?
Keeping all the systems on separate boxes would of course also be a whole lot tidier. For the sake of that, I wondered if Docker could help or if it just adds to the complexity without real benefit.?
?
kind regards
