Hello all:
I was wondering, what soft should I use to have my own personal computer respond to a telnet connection from the outside?
I'm thinking about getting into my home computer from work through telnet.
What software should I use? I wouldn't like to have a full-fledged BBS running just to have my computer respond and let me list files and simple things like that...
Thanks for the info, I know too little of this 'telnet thing'... I'm feeling like Homer Simpson, going to install Jesus dancing macarena through telnet :p

Cheers,
Malvinas.

What OS are you running? If you're using Linux, I think there's a telnetd you can install. But for security, you should probably use SSH rather than telnet - and for that, it would probably be sshd (which may be made available by other packages).

For Windows, it looks like there is OpenSSH that you can install to provide SSH access:

I'd avoid telnet for this. Maybe passwordless SSH on an obscure port?

You *could* use Syncterm's ssh and bam, drop right into a SSH session. But again, not super secure.

I use the free Tailscale app to create a virtual private network on my computers, works pretty well.

I'm on Window$, I'll be checking out OpenSSH. Thanks for the info.
I have a Linux distro on a second computer where I'm working on setting up a music streaming service...
I might end up trying both...

Syncterm *can* act as an SSH host??
Also, what's not super secure about "*Secure* SHell (SSH)"?
Thank you very much for the info.

Yes, it can, though it's mainly for a user logging onto the BBS, not for providing shell access to the OS.

I'd use something like TeamViewer for getting into your home PC. I uased
to run it on my BBS PC so I could get into that PC remotely... worked
great. When I moved the BBSes to a new PC, I didn't set it back up
because I really didn't need it anymore.

SSH is fine, it's just sending passwords that's insecure.

key-based is more secure, passwords can be prone to brute-force, etc.

But look, who am I to lecture, I still run OS/2 and DOS machines.

All of these are blocked by my new office IT. I have been using Chrome Remote Desktop. No installer is needed for my Work PC, so I stay "hidden" from accessing my PC at home (cameras, 3D rendering, etc.)

When my IP changes due to a power out/reboot, I can still remotely access and bring my BBS back online when needed. (My Mystic Telnet BBS is running on a Windows VDi on an old Dell Server.)

I don't want to use TeamViewer, I dont *need* to get into my PC from abroad,
I just want to try out and learn how to use Telnet... It's an experimental thing only.

And you could only try to brute-force my computer if you found my *dynamic* IP... Where would you get that??

Reconnaissance techniques such as scanning a range of IP addresses in a network or using tools like DHCP snooping can help a hacker identify active IP addresses, even if they are dynamic.

But I'll shut up now, I'm not a model of network security, ha...

Hello Malvinas,

honestly there is almost nothing you can do on a windows box when you telnet in. its just a command prompt, but windows lacks the programs for command line.

I missed this post earlier, but I wouldn't use TELNET for this at all...

SSH is your friend, and I always turn off password authentication, create SSH keys on any computer you want to access the server from and copy their .pub(lic) keys to the server.

Tailscale is a local VPN service that would allow you access into your network, but I just run my own VPN - I use PiVPN.

Another option to further obfuscate the rest of your home network would be to run a router software like OpenWRT or pfSense would let you only put that one server public-facing...
