TCP Master/Slave question

Mark Taylor All Messages By This Member #44046 John, ? As the TCP-SLAVE side of a connection I assumed that I would never initiate a connection. I am seeing the following: ? 13:35:48T N5MDT-13>N4NVD-3 Port=2 <XID C P> 2=21 3=22a486 RX Paclen=256 RX Window=7? ? I have different ports for AXUDP (port 1) and AXTCP (port 2.) The above line is obviously the Port 2 Monitor and it looks to me like it is a connection request being initiated by me.? However, I am seeing a similar line to a well established and connected AXTCP link to N3HYM. ? ? Now, earlier today, I switched N4NVD from TCP (port 2) back to UDP (port 1) and restarted.? The UDP route is stable using port 1.? However, I am still seeing the above line in the port 2 monitor. ? So, what exactly is the XID packet?? When should I expect to see these cease for N4NVD? ? The axipcache1.cfg file contains only port 1 connections.? I do not see a port 2 cache file. Is there one that I can empty to stop these XID packets to N4NVD sooner than letting it time out on its own? ? ? Thanks -- 73, Mark, N5MDT Montgomery, Texas ? ? ?

John G8BPQ All Messages By This Member #44049 开云体育 Yes, that is a recent change to AXTCP/UDP. An XID is sent before the SABM to attempt to negotiate an ax.25 V2.2 connection. If the other send replies with an XID response a SABM is then sent. AXTCP Master/Slave only selects which end established the TCP connection, not which end opens the ax.25 link.
