[slime-devel] bogus Error: "Local socket address already in use"
I just updated slime. I get the following error: CL-USER(1): (swank:create-server :port 6666) Error: "Local socket address already in use" (errno 98) occured while creating a passive socket on 127.0.0.1 port 6666 . [condition type: SOCKET-ERROR] Restart actions (select using :continue): 0: Return to Top Level (an "abort" restart). 1: Abort entirely from this (lisp) process. Two things: 1. I am running a reverse ssh tunnel on port 6666 2. After taking the default restart, the connection actually works. I had no problem with a previous version. This is in allegro. Roman

1. I am running a reverse ssh tunnel on port 6666
Does that mean that ssh is listening on 6666? That would be a sensible explanation for the error.
2. After taking the default restart, the connection actually works.
The connection works after invoking the abort restart? It's hard to imagine that you had a working connection without creating a listening socket. It's more likely that some other process was actually listening on 6666, perhaps an old Swank server.

SLIME's source code for creating connections didn't change recently. Helmut.

I am not sure how the reverse tunnel works in ssh, but obviously ssh is not listening on the port in the normal sense. The purpose of the tunnel is to do port mapping in effect. I had been using a forward tunnel before which initiates on the client. Reverse tunnel originates on the server.

I can repeat the scenario. I get the error, then ^D and the swank server is running fine. I connect remotely on port 6666 and get the repl. I type (exit) and the very same lisp image exits.

I tried older swank and I got the same error - my mistake.

Appologies. Too many machines and configurations. I was starting swank in my .clinit.cl. Second attempt to start swank causes the error. Reverse ssh tunnel doesn't interfere with swank. Roman On Sep 17, 2008, at 5:10 PM, Roman Budzianowski wrote:
