TCP/IP Timeout
I am using Client Access 5250 emulation connecting to a model 270 at V5R2. The host has a public IP address so there is no VPN, etc. After 5 minutes of no keyboad activity my job is disconnected. Does anyone have any ideas on what I can do to keep my job active? Thank you.

Answer Wiki:
There are a few settings on the iSeries to check but i would doubt any would be set that low.
WRKSYSVAL QINACTITV, select option 5 to display. It's possible the setting could be at 5 minutes if this is after normal work hours and there is a scheduled job that resets this value.
The TCP keep alive parm TCPKEEPALV in CHGTCPA
and the Session keep alive timeout TIMMRKTIMO in CHGTELNA.
There used to be a setting in the .WS file in the private subfolder but i believe that was removed in v5r1?
I would verify with your network personnel if there is a similiar setting on there side.

Thank you, Whatis23. Mu QINACTITV is *NONE, TCPKEEPALV is 120 and TIMMRKTIMO is *CALC. I changed TIMMRKTIMO to *DFT (600 seconds) and will see if my session stays active for 10 minutes instead of 5.
If you are doing a 5250 connection to an AS/400 on an public internet connection without a firewall you are probably losing your connection while hackers are performing an colonoscpy on that system.
I found out I was connecting to a firewall after all, and it had a telnet timeout setting of 5 minutes. We increaded to timeout value to 999 minutes and the problem went away.
Thank all our you for your concern and advice.

Security is an issue, but hackers interpreting sdlc must be fewer in number.. It’s the passwords you need to worry about – have a predetermined new one for each session.

Do you happen to remember the setting onthe firewall that needed to be changed as I am having a similar problem with one of the AS400 connenctions please?
