Bitcoin Forum

I want to know, how to configure my host computer (Debian) in which I run bitcoin, to be reached externally.

Actually,


is useless.

Don't use telnet. It's unencrypted and your password is sent in plain text.  User SSH instead.  Open port 22 on your router/firewall and redirect it to your Debian box.  Then connect in using either SSH from a Unix box, or PuTTY from a Windows box

I use "telnet" as a simple way to test if bitcoin is alive from outside. I don't really want to manage bitcoin with "telnet". The goal is to use a real bitcoin client in the future.

Ah sorry, I thought you were wanting to connect in to a command prompt to control your client.

As you didn't provide much information I'll just list all the possible errors in your method.

• Bitcoin isn't running as a server/daemon
• bitcoin.conf file uses whitelisting of IPs or is forbidding remote access
• You're using the wrong port when trying to connect (maybe try default port 8333?)
• You're trying to reach the server from outside the local network and haven't configured NAT and/or firewall exceptions in the router

Thanks a lot for your feedback!


No. It's ok. Locally, I can "telnet" and "http" to localhost:8332 (with nonsense result, but it proves the daemon is listening).


The server has public address, with no NAT device. Perhaps I should take a peek to "iptables", but I think ports over 1024 are visible by default...


Only rcpuser and rcppassword are on bitcoin.conf.

But this is worth to investigate: the options in bitcoin.conf I'll quickly go to the wiki to dig out the matter.

Thanks again!
