So, I have been fighting with this for the past 2 days now. I have two separate computers, each running Ubuntu of course, and each has its own bluetooth dongle (same make and model). I can get each of the computers to bond to one another, but when I try to telnet via Putty or any other means I get the following error:

Connection Refused

(#via Putty)

or

Can't connect RFCOMM socket: Connection refused

(#via rfcomm in the terminal)

To give you a bit more info., I have also tried to connect each computer using ssh over WLAN. However, I get the following error:

ssh: connect to host HOSTNAME port 22: Connection refused

Alright, I figured out how to manually get the rfcomm0 by doing the following:

cd /dev

sudo mknod --mode 600 /dev/rfcomm0 c 216 0

Then I uncommented the following lines in my /etc/bluetooth/rfcomm.conf file:

rfcomm0 {

      bind yes; #set no to yes if it is not already set

      device <bdaddr>; #where bdaddr is the address of the bluetooth with which you are trying to bind

      channel 1; #I think any channel will do

      comment "Add whatever you want here";

}

I'm not sure as to whether or not I needed to do the first portion once I uncommented the rfcomm0 stuff, but it worked nonetheless. Once I had that bit working, I tried your command Bemfica along with a sudo rfcomm -a to check the connection. Finally, I transferred a file by typing: bluetooth-sendto <filename>. So, it looks like I'm at least moving in the right direction. I'll be back with more questions/answers.
