Re: Demo Thursday 2024-05-30

 

Hi Bernhard,

thank you for setting up your X.25 service.? I have tried to connect to your system using xotpad?with an explicit gateway, but that failed:

mecipt-1 1010_% xotpad -g 22227100
Error: Custom { kind: Other, error: Os { code: 51, kind: NetworkUnreachable, message: "Network is unreachable" } }

I also tried to connect to port 1998 on , but that timed out as well:

netzhansa 1027_% telnet 1998
Trying 2001:4dd0:af15:dfcd:5e49:79ff:fe37:bcc8...
^C
netzhansa 1028_% telnet -4 1998
Trying 78.34.235.229...
^C

Are you sure that your firewall and the port forwarding is set up correctly?

Hi folks,

I'm doing a small presentation on TELEBAHN and other retronetwork things this Thursday, and if you have any gear that you could run between?16:00h and 20:00h UTC,?that would be great.? If you bring something up, please also let me know the NUA.

Thanks!

Cisco 25xx, 18xx, 26xx, 28xx will all do and can be had for cheap.? If you plan on connecting actual X.25 gear, you'll also need the right cables.? 25xx needs CAB-232FC, newer models typically need CAB-SS-232FC for V.24. I don't know the V.35 and X.21 cable names right now, but if you get them, you need the DCE variant as well.

If all you want to do is xot, you can also compile on a modern machine and use?that to?connect to TELEBAHN nodes.

Re: Question about connecting from Cisco/Sparcstation

 

Not familiar with RS-530, but I've successfully connected a SPARCstation 10 to a Cisco using a CAB-232FC (the older version, not the SS version) - you may need the DCE version for the Cisco (I assume CAB-SS-530-xC) as I imagine the SPARCstation will be DTE. I swear I finally got to understanding this when setting it up, but have now forgotten :-)

On that note, it seems that (at least on the IOS that I'm running on 471) you sometimes need to disassociate and then re-associate the XOT profile for changes to take effect... i.e. every time I try new parameters I have to do "no xot access-group 10"; "xot access-group 10 profile TELEBAHN".

I'd like to connect my old Sparcstation 1 to Telebahn. I've got a Cisco 1841 with a WIC-2T, can I use a?CAB-SS-530MT cable to connect the WIC-2T directly to the serial port on the Sparcstation? And then run Sunlink on the Sparc to connect to Telebahn??

Btw my dad worked for Telenet back in the 80's and when I told him about this project, he said "why would anybody want to do that?"??


Re: Question about connecting from Cisco/Sparcstation

 

That did the trick. Thanks! I just had to remove the X25 TELEBAHN profile and now it works fine

Some Sparc serial ports can be set to RS423. I think you might get lucky with the SparcStation 1; and further assuming it’s similar to the 4 or 5; they could. ?

I configured my Cisco as per the sample?configuration on the x25 website but it seems that I'm still missing something. Looks like the error is " ?XOT Call Confirm packet, Bad value for facility, Window size is not within permitted range." I'm able to connect to 471041 just fine from xotpad

It doesn't look like the Sparcstation 1 has jumpers on the motherboard to set the serial ports to RS423... but I also have a Sparcstation 4 and a 10 so I guess I'll just use one of those instead. Thanks!

Some Sparc serial ports can be set to RS423. I think you might get lucky with the SparcStation 1; and further assuming it’s similar to the 4 or 5; they could. ?

Hello everyone,

I'd like to connect my old Sparcstation 1 to Telebahn. I've got a Cisco 1841 with a WIC-2T, can I use a?CAB-SS-530MT cable to connect the WIC-2T directly to the serial port on the Sparcstation? And then run Sunlink on the Sparc to connect to Telebahn??

Btw my dad worked for Telenet back in the 80's and when I told him about this project, he said "why would anybody want to do that?"??
