Good 3270 emulator with SSL/TLS encryption?

SlowCoder · 07-15-2008, 03:33 PM

There appear to be plenty of 3270 packages for Linux for straight 3270. But I need one that is capable of SSL/TLS. Any ideas?

There are - where ???. Only (free) one I've ever got to work is x3270.

A 3270 uses either SNA or bisynch. I suppose you could have a 3270 emulator that communicated via some other protocol; I know there is a 3270 emulator that uses TCPIP out there somewhere, but I wonder where the advantage is. SSH is so very different from SNA or bisynch (both conceptually and architecturally) that I don't really see why you would want to do it.

edit:

Sorry, you said SSL not SSH. My bad. THe emulator TN23270 does TCPIP, but I don't know if it is available in a Linux version.

Beat me to it ...

All the 3270 emulators (I've used) run over IP - they're emulators after all. x3270 is SSL aware - I had trouble with "odd-ball" screen sizes (say 142x60), but I'm told it's do-able.

I'm sure X3270 already has this as standard.

(I'm also using this package in the Hercules Emulator -- Running MVS (OS/390) etc on a laptop !!. Works fine.

From x3270 manual:

Code:

Prepending  an  L:  onto hostname causes x3270 to first create an SSL tunnel to the
host, and then create a TN3270 session inside the tunnel.  (This function  is  sup-
ported only if x3270 was built with SSL/TLS support).  Note that TLS-encrypted ses-
sions using the TELNET START-TLS option are negotiated with the host automatically;
for these sessions the L: prefix should not be used.

There are some implementations in Java too, but I prefer the x3270 to connect on "Big Iron"
