Hello,

I'm trying to build Synchronet with SSH support.
I see libcl.a being builf but SSH doesn't start, or bind to port. Telnet binds to port 23, as expected.

I have checked and the libcl.a is not linking to the executable.

Head's up: you're posting directly here using a QWKnet account, not your "regular" user account on Vertrauen (Jordanjm42) that you created.

I'm trying to build Synchronet with SSH support.
I see libcl.a being builf but SSH doesn't start, or bind to port.

Does sbbs display or log an error binding to the configured SSH port?

I have checked and the libcl.a is not linking to the executable.

ldd wouldn't show you that.

I'm building on Ubuntu 24.10.

ldd shows dynamically linked shared objects (*.so files), not static link libraries (*.a files) - so that is normal.

Ive watched sbbs run, there is no attempt to bind to port.
I've checked all the logs I could find with the same result, nothing indicating an issue. This leaves me to believe the Terminal server is not attempting to bind to the ssh port.

make -f install-sbbs.mk SYMLINK=1 works
I tried: make -f install-sbbs.mk SYMLINK=1 STATIC=1 which failed with relocation R_X86_64_32 against hidden symbol `__TMC_END__' can not be used when making a shared object


libcl.a is built in /opt/sbbs/repo/3rdp/build

(Note: installer originally tried libnettle-dev, but on Ubuntu 24.04/25.04 it’s replaced by nettle-dev.)

I believe since these do not show results, that libcl.a isn't being built in. nm -A sbbs | grep cl_
objdump -t sbbs | grep cl_

Ive watched sbbs run, there is no attempt to bind to port.

Are you sure about that? If Telnet and RLogin are working, then you'd see the attempts to bind to *those* ports. And if you have SSH enabled (which is enabled by default), then you'd see it attempting to bind to *that* port too, like this:

2025-09-09T13:33:54.256530-07:00 git sbbs: term Initializing on Tue Sep 9 13:33:54 2025 with options: 13020
2025-09-09T13:33:54.256581-07:00 git sbbs: term Loading configuration files from /sbbs/ctrl
2025-09-09T13:33:54.533201-07:00 git sbbs: term Telnet Server listening on socket 71.95.196.36 port 23

2025-09-09T13:33:54.904038-07:00 git sbbs: term SSH Server listening on socket 127.0.0.1 port 22

I've checked all the logs I could find with the same result, nothing indicating an issue. This leaves me to believe the Terminal server is not attempting to bind to the ssh port.

Only if you have SSH listening disabled for some reason.

(Note: installer originally tried libnettle-dev, but on Ubuntu 24.04/25.04 it's replaced by nettle-dev.)

I believe since these do not show results, that libcl.a isn't being built in. nm -A sbbs | grep cl_
objdump -t sbbs | grep cl_

You're on the wrong the track. Just look more closely at the log or console output from sbbs and your configuration in SCFG->Servers->Terminal Server and the output of 'netstat -l' or 'ss -l'.

The console or log output of the sbbs terminal server when it first starts up. --
