• Crazy BBS connections

    From Sam Alexander to All on Monday, March 21, 2022 12:33:52
    I'm finally in a place where I can setup a new board -- probably will just be for my own benefit and the fun of doing it. I'm quite surprised at the barrage of connections I started getting right out of the gate! I'm getting telnet and ssh connections almost constantly, about 3-5 a minute if not more. Trying randon usernames and such. I guess this is normal now'days? I'm running sync at home over my broadband connection, so I guess it's people just scanning ports and ip's.

    Anyway just curious if this is quite common ... I remember it being so last time I ran a telnet board 15+ years ago, but not to this degree.
    Thanks- Sam

    It was the same back then. Just bot scans looking for systems with default passwords, misconfigurations, or unpatched exploits.

    Yes, it is common/normal.

    very common.

    Example, on my fairly open linux box, these are all the attempted ssh connections within 24 hours. Deal with it with fail2ban or something
    similar - that I have but seems I need to tweak it.

    You might want to avoid using the standard ports for telnet/ssh/rlogin.

    The problem with changing the standard ports is that most users probably aren't going to bother changing their port configuration for a particular BBS. So if you change the ports your BBS uses, you'll probbaly see a dramatic drop-off in users (not that we get many in the first place).

    It's normal and don't worry about it unless you really want to. Scripts are attacking your server, but they wouldn't know what to do if they got in. They're expecting bash or some IoT device, not a BBS.

    The worst thing that ever happened to me was that spurious SSH connections would jam up all of my nodes and take forever to disconnect. I did something slightly hacky with text.dat and a script to disconnect them more quickly. Can't remember the details right now.

    There's stuff you can do to mitigate it a bit, but you'll also be fine if you ignore it. I mostly do, and I'm still alive.

    This may reduce the number of connections, but I wouldn't bother unless these connections present an actual problem (which they rarely do). No sense in complicating things for yourself or your users (hah) unnecessarily.

    I use default ports for everything except where my ISP makes it impossible.

    I have my router take care of DOS and DDOS, and I only open ports I actually use on my BBS computer, I also block ip's that try the password guess game and I have a jibberish text file that is sent to them each time they try to spam me.

    I'm building up a nice collection of netblocks.

    If I was smart I'd just move ssh to another port and be done with it, but I'm not a huge fan of security by obscurity.

    there's some real bad ones. the ones i hate are the ones that claim to be legit scanners. they never stop and hit me all the time, all day long.

    with bots going in my login i have a capcha thing that only 2 idiots failed in many years. they actually had to write something wrong and then confirm it.

    what this script does is block everyone that connects. then they solve it correctly and they are removed. that way bots that disconnect are in the list.

    but blocking is real fruitless. when you block 100, there's another 10,000 to replace them.

    Yup, sounds normal.

    I guess I'll need to increase the nodes from 4 to 8, at any given time 2 to 3 are tied-up with this mess, once even all four were tied-up. Can you give more details on how LoginAttemptFilterThreshold works? I read the docs, and other than suggesting not to set below 10 i'm unsure what this does. I'm often seeing the same IP trying dozens of times, and though I've added some to the ip.can file I'm not sure I have this working correctly.

    This is on Sync built from the most current git release on Linux.

    I thought of that, but this doesn't seem to be norm for most systems. My biggest concern are these connections tying up all the nodes, already seen it happen once. I'll probably increase from 4 to 8 due to this.

    yes they are. i devoted the last 25 years of my life running services for sysops and users.

    when you put up a roadblock when a user has a very short attention span and tollerance for things, you are really screwing yourself over.

    lets say there's 2 amusement parks. one on each side of the road.
    one is cheaper but you have long waits. with the other one, it's more expensive but there's no wait to get in and there's a very short wait for the rides. it's ran better than the other one.

    the first park would be out of business in a year.

    you're a bit late to the show and i assume you are one of those guys that is into this stuff for the technology aspect, and learning new things.

    I have always been in it for the users. I think about what they want, i had friendships with my users and i gave them what they wanted. for me it was always about the users because that is what a bbs system is for. it's providing service. a lot of people don't realize this.

    i've seen hundreds of guys that say they 'run this for themselves and don't care if they get users' shut down with the reason being their system is dead and they have no use.

    so yes, obviously you are doing something stupid if you make it harder for people to use your system when they can go someplace else with no hassle.

    Half of the top 10 most popular sites in the voting section of my

    or inflating the degree this is a "hassle".

    I'm not late. I've just been away for a while.

    I have been involved in computer technology since 1981. I ran RBBS and PCBoard multinode dialup boards for well over a decade. I was a Fidonet coordinator with a Planet Connect feed servicing a large number of
    downstream nodes for over a decade.

    I've been managing and securing IP networks for nearly 30 years.

    Since 2017 I've become re-interested in BBSes, mostly because I was
    amazed to find out so many still existed. You're correct that I'm not
    looking to build a community on my BBS at this time.

    The concept of moving to nonstandard ports is dated and not useful anymore. It accomplishes nothing other than making it more difficult for users to connect. For all the people that say otherwise, I’ll wait to see all of the examples of exploited BBS systems that were using 22/23.

    I think the reason that some sysops use non-standard ports is to cut down on bots busying their nodes (attempting logins or just waiting to timeout) and possibly denying service to legit users.

    I'm finally in a place where I can setup a new board -- probably will just be for my own benefit and the fun of doing it. I'm quite surprised at the barrage of connections I started getting right out of the gate! I'm getting telnet and ssh connections almost constantly, about 3-5 a minute if not more. Trying randon usernames and such. I guess this is normal now'days? I'm running sync at home over my broadband connection, so I guess it's people just scanning ports and ip's.

    Anyway just curious if this is quite common ... I remember it being so last time I ran a telnet board 15+ years ago, but not to this degree.
    Thanks- Sam

    I've been waiting for someone to say that, which is a valid reason I guess. I get maybe two concurrent attacks/scans at the very most. Whatever, still a reason that makes some sense.

    But so far, everyone who brings it up has said it's for security reasons. Which just doesn't hold water anymore.

    Which accomplishes pretty much nothing. No security impact. Maybe have to run a couple more nodes for the times when you end up with a couple nodes taken up by scanners and bots.

    Something doesn't become smart just because hundreds of people do it. I'm not about to eat shit because trillions of flies seem to enjoy it.

    There are legit reasons for using non-standard ports - eg. your ISP prevents you from using the proper ones - but more often than not it's done for silly reasons. There are proper ways to deal with bots and hack attempts, including just ignoring them.

    i do stupid things all the time, lots of times i just do it to be interesting.

    but there's common sense stuff and people need to attempt to think sometimes.

    you don't want to make things difficult for an audience that would rather just drop their connection on you and watch some memes.

    i dont care if 1000 people are running their bbses and other things on wrong ports and think it's a great idea. it's not. you're on the internet and this means you are going to be scanned all day long no matter WHAT you do.

    Funny you should mention ngrok - I just saved this to my pocket account to read later:

    https://jerrington.me/posts/2019-01-29-self-hosted-ngrok.html

    Roll your own Ngrok with Nginx, Letsencrypt, and SSH reverse tunnelling

    Ngrok is a fantastic tool for creating a secure tunnel from the public web
    to a machine behind NAT or a firewall. Sadly, it costs money and it¼╟╓s proprietary. If you're a developer, odds are that you're already renting a server in the public cloud, so why not roll your own ngrok?

    It turns out that you can do it using free, off-the-shelf tools, with no sophisticated scripting required!

    In fairness I did mention a VPS option, though specifically for hosting.
    Was thinking of something similar instead of NGrok myself, just passing
    80, 443, etc to my local system(s) where 80/443 would be a configured reverse-proxy on my local side.

    Probaly Caddy over NginX as it's much easier to configure/use.

    That's actually what the original poster seemed to be asking about and
    what I thought I was providing an OPTION for him to deal with it.


    When I explain ports to my non-technical friends and co-workers, I explain
    the system being a large factory building with mulitple doors dedicated to specific customer or vendor traffic. If a caterer is bringing in food, you wa nt him to use the dedicated kitchen entrance. That may bring up the
    argument that someone who wants to sneak in the building knows doors 22 or
    23 are the kitchen entrance. You may have to lock those doors down and tell the caterer to use another entrance. Is this an issue? Not really if the caterer knows which door to bring the food in. That information is provided
    by the building manager. If you want to invite a select group of people in, you would have to advertise wherever else these people go and inform them as
    to which non-common door to enter from.

    To continue with your analogy. You’re only keeping out the people who would normally park in the parking lot and only check the front door with the sign on it that says kitchen.

    Any idiot who wants to break in can just walk around the building and see where the other doors are, walk up to them, and rattle each one to see if it’s locked or not.

    The caterers have a key to the door they’re supposed to enter because you gave it to them. Doesn’t make a difference at all which door you give them a key to. They’re all locked doors and they all work the same way.
