It sounds like the way to get this working would be to have whatever sits in fr
nt that accepts the 1st inbound telnet - have it initiate an outbound binary te
net connection to the second host.

Yes, I think so. I thought that Synchronet might work doing that but have found that I also have issues attempting to download after I have opened a telgate connection to another bbs from Synchronet.

I am not aware of any frontends that will properly initiate the binary connetion. :(

Mystic can do a double telnet back to Mystic. That is the only working example that I'm aware of at the moment. Looking to see if there is a work-around to solve this, which likely has something to do with the telnet negotiation process. Maybe some need it hard coded - or if there is a way to send the parameters to "both telnet sessions". Maybe some are doing it on just one of the telnet sessions and not both.

I believe the way Mystic works is that its behavior varies depending on the connection circumstances. For example:

If you are connected via a telnet client and you do an outbound telnet, then Mystic knows that your telnet client can handle the telnet negotiation, so it connects but passes any telnet negotiations directly to your client and any response from the client directly to the outbound telnet server.

But if you are connected via SSH or RLOGIN and you do an outbound telnet connection, then Mystic knows that it must translate from telnet to SSH/RLOGIN and it will handle all of the telnet negotiations so they never reach your client (because your client won't be able to handle telnet stuff).

I will release D'Bridge 10 Finally For Freakin' Linux Edition when you do.

At one point I was receiving at least a Netmail or two *per week* about it.

to your client and any response from the client directly to the outbound telnet server.

That being the case it sounds like when nested telnet sessions go to non-Mystic systems, something isn't getting passed to the client for negotiation. Or maybe it is trying to negotiate with the original (non-nested) telnet and not the client.

Just thought of something to try. Putting GameSrv/TelnetDoor in front of Mystic and see if I can do a successful transfer...

If I had to guess whatever layer is being used (SIO, etc) doesn't do telnet negotations at all or doesn't know when to request binary.

I need to set up a test with other systems so I can see if sending some telnet commands as a client can resolve it. I can't remember when the last time was that I tried to test anything like this with a non-Mystic system (out of my
own "laziness" of not setting up another BBS software to test with) so I need to do that to see what I can figure out.

Except transfers work fine with no nested telnet using SIO. Going directly to it works perfect.

Now that the weekend is basically here, will try setting up TelnetDoor/Gamesrv in front of Mystic and then try an xfer. Very interested to know the results of that one, too.

Appreciate your help in understanding this and if there is a work-around.

Just tested using GameSrv/Telnet Door in front of Mystic and then tried a transfer. At least there is consistancy that it didn't work. Same thing where the xfer would start, get a bunch of errors and terminate.

The big mystery here is how Mystic->Mystic telnet and then xfers work. That appears to be the only working example. Very intersting, for sure.
