cannot bind to port [listen_loop(), ratproxy.c:1609]

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile on Mac OS X 10.4.11
2. Run ratproxy with $ ./ratproxy -v testout -w testoutfile -d
"http://www.domain.com" -lfscm
3. See error

What is the expected output? What do you see instead?

Should have run, instead showed the following error:
ratproxy version 1.50-beta by <lcamtuf@google.com>
SYSTEM ERROR : cannot bind to port [listen_loop(), ratproxy.c:1609]
     Message : Can't assign requested address

What version of the product are you using? On what operating system?
Mac OS X 10.4.11

Issue is the same on 10.5.4 OSX

A temporary workaround is to use the -r option. This will expose ratproxy to 
external
systems, so just be careful.

This is an unusual behavior; do you have loopback interface up on the machine, 
and
configured to use 127.0.0.1?

If not, this is a system configuration error; try executing 'ifconfig lo 
127.0.0.1
netmask 255.0.0.0 up' as root.

Yep, lo0 is configured and working, nothing else is listening, tried with a 
variety of ports.

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
    inet 127.0.0.1 netmask 0xff000000 
    inet6 ::1 prefixlen 128 
    inet6 fd39:ae47:d465:4a13:other:crap:from:v6 prefixlen 128

[Also, you almost certainly do not want to -d http://site.com; -d site.com is 
the
correct syntax]

Ok, got it, I think. Can you try making the following change to ratproxy.c, 
around
line 1589:

  struct sockaddr_in saddr;

...to:

  static struct sockaddr_in saddr;

...and recompiling (make clean all)?

(According to some reports I managed to dig up, MacOS X may not always ignore
sin_zero data on INADDR_LOOPBACK bind attempts, so this is my best guess).

That did it, confirmed, working on 10.5.4 - thanks!

Cool, I'm gonna prepare a new tarball shortly.

This should be fixed in 1.51 beta, now up.

• Changed state: Fixed

That worked for me as well on 10.4.11
