The problem only seems to appear if we close the 3270 window, instead of using #cp disc. If memory serves me (which is always doubtful), we have been using the "close the window" method for several years, under the assumption that (since the days of modems), CP allows a machine to keep running (as long as it has SET RUN ON) when it's console connection is broken, even if it's running a 2nd level OS.
Do I mis-remember the design? Regards, DJ THANK YOU for deleting my address (unless it is pertinent), all other addresses, and personal information from this e-mail, if you plan to forward it. THANK YOU also for using "BCC " instead of "TO" and "CC " when initiating e-mails to multiple users. This may help prevent spammers and hackers from obtaining addresses and thus may prevent spam and/or identity theft. -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Alan Altmark Sent: Wednesday, October 15, 2014 1:07 AM To: [email protected] Subject: Re: can't SSH after 3270 disconnect On Tuesday, 10/14/2014 at 12:23 EDT, Doug <[email protected]> wrote: > Could it be that the guest is getting sent an interrupt when the terminal > disconnects and the guest interpreted it as shutdown reboot now. > I forget where to check this but am sure the masters on this list know. Network traces are the only reasonable way to solve this problem. Divide and conquer, as I said previously. Get simultaneous tcpdumps of the end user machine, the VPN server, and the target Linux machine. You're looking for the SYN, SYN/ACK, ACK open sequence (e.g. on port 22 for ssh). If you don't see them flowing from one end to the other, then you know where to look for the culprit. Or just hand it to some network techs to deal with.
