Mongrel users - Jul 2006 - (OS X) Address binding still exists after terminating session

[using mongrel-0.3.13.4 pre-release, OX 10.4.7]

I have a slightly annoying issue under OS X: If i terminate the  
session that ran the mongrel process (by closing terminal window --  
hey, it happens!), subsequent attempts to start mongrel give me the  
following error:

/usr/local/lib/ruby/gems/1.8/gems/mongrel-0.3.13.4/lib/mongrel/ 
tcphack.rb:12:in `initialize_without_backlog'': Address already in use  
- bind(2) (Errno::EADDRINUSE)

I suppose, because mongrel wasn''t stopped properly, the address  
binding still exists somewhere. However, since the actual mongrel  
process has been killed, i have no idea how to unbind the address and  
port otherwise, so i usually have to resort to restarting the whole  
system (ouch!). This problem does not exist with WebBrick or lighty,  
so maybe this can be fixed? Otherwise, how can i manually release the  
address from its binding? Thanks for your help.

That error means that an existing process is using that port on this
system.  It''s not an issue of unclean shutown--it means that Mongrel
is still running in the background.  Try ''ps awwwx | grep
mongrel'' to
find its process ID, then use ''kill'' to kill it.

you right, the process was still running.  I had actually grepped for  
a  "mongrel" process before;  it turned up empty because, in fact, i  
had started it as "script/server" (Doh!). Sorry for the noise (and  
yes, i will put down that crack pipe!).

I have also found that my mac os x terminal windows need to be expanded
really big to do:

ps aux | grep blah

especially for ruby proceses with paths like:

/usr/bin/nice -n 3 /usr/local/bin/ruby ....

I assume this is because it is really piping ps aux to the screen and then
doing the grep, and if the screen is not big enough, it wont find the full
path.

netstat -ano

should also show you what "stuff" is listening on all your ports and
so you
can see those 8000 ports still on.

If you ''ps auxww'' then ps will pass everything to grep.

Hey Scott,

Cool finally meeting you last night.  I wanted to see if you were
willing to work with me and two other guys in doing a security test of
Rails and Typo.

Basically, after today''s nasty little security hole I got with DHH and
two security pros I know and we''re looking for a small fun first
project
to try out a security test with.

Since I know you, you wrote typo, typo is popular, I figured it''d be a
good start.

If you''re interested, get ahold of me and we''ll start putting
this
together.  I''m thinking you could help them get a good tour of it, help
when bugs are found, and just generally learn about how they attack
stuff.

Thanks.

Zed

Sounds good to me.  As usual, I''m afraid of what they''ll find.

I''m going to push a new Typo release tonight to deal with the 1.1.5
mess, but after that I should have time to work on this.

Contact me off-list for scheduling details :-).

transcontinental and writing typo, all in the last 24 hours; but i''m ok
now
