I've been running my old crappy 99% stock BBS for years now, and the ammount of
times I get hangs from scripts hammering away on port 23 is absolutely insane. >I have setup (well at least the commands didn't complain, no idea if it >actually works) rate limiting on inbound port 23, but it doesn't stop.. As 2016

I ran into so many problems just over the past month with that, right about
the time that the Clinton e-mails leaked (oddly), that I decided to at least temporarily shut down telnet for my OS/2 / SIO / GT Power board and have
routed the telnet traffic to Synchronet, which I was using just for a web board.

In my case, the GT BBS software did not have any issues with the hammering... it was the SIO/VMODEM software that would hang after being hammered non-stop for so long.

Odd thing... about a week after I switched to SBBS, the hammering has mostly stopped. I added some things to the CAN files that may have helped but, mostly, I think it stopped on its own.

I would consider switching permanently but I have not had much time to figure out how to get the DOS doors running under SBBS linux. So, while dial-up
still gets GT, what few telnet users I had who liked the doors are sort of
out of luck for now.

I have actually thought about trying to set something up, using the SBBS door that telnets to other boards, so that folks can telnet from the SBBS locally over to the GT board.

Some of us have had fairly decent success with DOS doors under DosEmu. I have a number of them running this way with SBBS on Linux.

What flavor of linux are you running? There might be some help out here if you inquire.

Others with this problem have had success using Mystic as a front end, using its matrix menu. Mystic takes the sting out of the probes, adding them to its block list. Legitimate users get passed on to SIO.

I haven't done this myself, but I know others who have with success.

That would work. Similar to the Mystic solution, though the Mystic matrix menu doesn't require a login before being transferred to the other BBS.

Oh good, there are like TWO of us now! I did a test upgrade to Warp 3 & 4 to see if that helped, and it sure did not. So back down to OS/2 2.0 WR06100 for me.

Sigh, every time that 'hacker' 4-chan guy gets out, all hell seems to break loose... :-\

Yes, SIO is the weakest link, for sure. It is annoying as frankly OS/2 is the best way to run multiuser MS-DOS Doors, bar none that I've found. But machines get faster and faster, I may break down and try some text mode Qemu passthru along with some samba server or something in the middle. DOSBox can't lock, but booting MS-DOS with a lan card to a shared drive ought to do the trick, just have to setup scripts to pass it flags and stuff, I guess build custom boot disks and script it all out in some insane fashion..... Or just suck it up, and keep OS/2. It's too bad Ray Gwinn just up and disappeared..

Others with this problem have had success using Mystic as a front end, using its matrix menu. Mystic takes the sting out of the probes, adding them to its block list. Legitimate users get passed on to SIO.

I was thinking of something to front the OS/2 SBBS, but hadn't really gone that much further after I setup rate limiting...

I haven't done this myself, but I know others who have with success.

It may very well be worth looking at.

Interesting. Do you mean the Mystic BBS software or is this some other
Mystic? I guess it automatically sniffs out the probes? I wonder if it
could pass straight to the other BBS software without SIO/VMODEM.

I will have to look into that.

Somewhere out on the web there is a example of some scripts & packages that will allow a DOS-based BBS software (running under DOSemu) to "answer" a
telnet connection under linux. I tried that once. It actually worked. However, I was not comfortable with what might happen if it got too many hits at once... like, would it dump a user to a command prompt or something?

My recollection is that I had to install a different-than-default debian package to handle the inbound telnet traffic. It could be set up, using a script, to call dosemu and was able to function as a virtual modem so well
that GT actually accepted the connection (like VMODEM does, and like none of the Windows viturals do).

That is also on my "one of these days, I need to try it again" list. :)

Yes, Mystic BBS. It has a "matrix menu" feature, which can be used to select between different BBSs, before login.

It was probably all coded in that Microsoft 286 MASM pre-release thing going back to the old days of Microsoft OS/2 2.0, since Microsoft only extended the 1.0 kernel to support 32bit functions, but at it's core it was still 16bit... Something that proved to be utterly beyond IBM's capabilities.

I guess in the same light, it's just as well the L4 port of OS/2 never really saw the light of day, nor opened sourced.

In the same light, I guess it's why UNIX clones are so popular, but nobody ever coded an OS/2 clone. It was just too good at running Windows 3.0/3.1 standard mode stuff, and MS-DOS apps.

I think it was tried, or at least theorized. Once upon a time there were
folks wanting to clone all sort of dead and no-longer-supported OSes. Some
had minor success, a few did not get past theory, and a few (like FreeDOS) actually got a fully functional OS going.

It may have been that whoever consider cloning OS/2 figured that the
emergence of a commercial successor, eCommstation, made it not worth their while.

Is there still a need for SIO/VMODEM aside from bbsing? Maybe the new
