Hello All,
I have discovered a nasty little bug in MBSE: if you go to change your
user signature when online with MBSE, MBSE abends with a "malloc():
unsorted double linked list corrupted" error and this is a
reproducable error. I cannot find anything in any of the logs about
this and this is the last thing I saw in system.log before the crash:
===
+ 15-Feb-2022 22:41:12 mbsebbs[2697] Menu[1] 319=(Change .signature
file),
Opt: ''
+ 15-Feb-2022 22:41:12 mbsebbs[2697] Sean Dennis will edit his
.signature
===
I do not know if it affects MBSE under other distros--I use Devuan 4.0
Chimera--but I wanted to let you all know. Andrew is working on
squashing this bug and I did open a ticket on it.
Can I 'assume' that this is when logged in as a user via alternative screens using say ALT/Ctl/F1 ?

This if you are connected to the BBS via telnet or SSH and attempt to
change your user signature.

Can't test this as I cannot connect to my system as it says that connection refused - cannot find where this is happening and by what.
Just have to remember how to tell a budding user to initially log in as bbs - been so many years ago :)

Are you trying to connect via telnet or SSH?

I have a line in /opt/mbse/etc/issue that reads "New users: use "bbs"
to create an account."

Thanks found it, now to find out why the system rejects calls using
telnet or ssh, Again!

Telnet connections are handled through inetd or xinetd normally,
depending on your distribution. The SETUP.sh script creates the
necessary entries automatically based on which is detected when you
run it. The telnet entries are disabled by default, so you would need
to enable them.

Hmm, wonder if it is the modem or router but the router should be
passing on ports 22 and 23.
Hello Vincent!
Did you get your ports/services figured out yet?
A good first point of call might be doing an external port scan on
your bbs ip or use a service to check for open ports.
No, I have reset the VM router, logged in to it and stopped the firewall (as a
modem it should not be using it as far as I know), saved settings logged in
again and changed it back to a modem only with no wi-fi etc.
Rebooted it, rebooted the Asus router, reboot the system and still have the
same problem - I would say I am pulling my hair out (if I had any) as totally
at a loss som any ideas are wellcome -

Can you describe your network topology a bit more? (Link to a simple
diagram if you have one).
It sounds like you have 2 x routers in the loop? Does this mean you
have a double NAT environment in play?

What can I use that is Linux based that I can do a port scan ?

You want to use something that is outside of your LAN to check.
The website I like to use for port scans is:

Haven't had a problem yet with it.

Thanks for that and found a config error for ftp server now fixed.
I have made a bookmark for it just in case it needs to be used again.
