Use the rotary command on the async port that will be your destination. ?I.E. ?rotary 99. ?This represents the last two positions in your 8 digit X25 address.? ? Then use ip host and/or x25 host commands to express the first 6 digits.? ? I can post an example later on.? ? John On Saturday, July 2, 2022, 1:51 AM, David Kuder <dkgrizzly@...> wrote:

I had to add the following lines to get any pad connections to go through on the 2620:
x25 profile TELEBAHN dxe ?x25 facility windowsize 10 10
?x25 facility packetsize 1024 1024
?x25 subscribe packetsize permit 32 1024 target 512 1024
?x25 subscribe windowsize permit 1 16 target 2 10
with those lines applied I was finally able to connect to JJ's and I also managed to get an inbound PAD to VTYs setup -DK |

开云体育Evan Stewart and I ran into that window size issue a few days ago and then I thought it went away. ? I’ve been using a bunch of different IOS images on different platforms so that may be part of it but perhaps simply lower the window size is an easy enough fix. ? John ?

开云体育And I just checked and the device David was connecting to on my side was still set at 10 so that may be why he needed to change his side to 10 also.?? I guess it is NOT a negotiated parameter. ? I’ll change my win and wout back to 15 to see if that works for David. ? John ? From: [email protected] <[email protected]> On Behalf Of john jones via groups.io

I was still able to connect just now without changing anything else on my side.
The secret sauce I found for bouncing connections to other hosts based on incoming connections is this: ! line vty 60 63
?exec-timeout 0 0
?vacant-message ''
?no login
?rotary 91
?autocommand telnet actual.host.name port /quiet
?no activation-character
?transport input pad
?autohangup
!
rotary is the subaddress for that pool of lines. no activation-character says don't wait for the user to send any characters before sending out the motd / login / running commands
vacant-message '' gets rid of any "press a key to activate this console" type messages you can put other commands in autocommand instead of telnet, just be careful that whatever command you run doesn't dump out to a shell when done.
I've got show clock running on 78323590 which dumps the current date/time as synced from pool.ntp.org and then disconnects.(menus using menu-exit will return to a shell instead of disconnecting. use exit to disconnect) if you're using both direct mapping and menus, you may want to use alias exec to define the commands so you can easily change them one place for both. ! ! alias exec tpcbbs telnet tpcbbs.local /quiet alias exec tpcbbs menu offline alias exec starwars telnet towel.blinkenlights.nl /quiet alias exec telehack telnet telehack.com /quiet
!
menu offline title '
Sorry. That host is currently offline.'
menu offline prompt 'Press RETURN to continue.'
menu offline command q menu-exit
menu offline default q
menu offline single-space
! Now that I've sort of figured that much out, I can't seem to get the async lines to respond to telnet anymore, which I had working yesterday. They connect, but I never get anything back from the modems, and then the connection times out. If I manage to get that working again, I can split the modem pool in half and call it a success. |
