sc_serv crashes on connect

Hi,

my config is like any other, port 9500, a nice password, no logfiles (!!)...

But, when I start the sc_serv as any user but root, the server crashes on the first listener-connect!
Here from the logfile

<02/01/04@03:34:05> [source] connected from 212.202.20.22

<02/01/04@03:35:01> [dest: 81.2.xxx.xxx] starting stream (UID: 1)[L: 1]{A: Winamp/2.x}(P: 0)

However, after the connect the server crashes without any error-message...

If I'm logged in as root, there's no problem!

Anyone can tell me why?

Greetz,
Lopez

I recognized, there IS an error, an segmantation fault, look:

I found the error, and a new sc_serv bug!!

It's about the file-permissions on *nix-servers, but not what you think!

So I log in with ssh, and I am in my homedir. Now I cd to anywhere else, letme say /root (where I have no permissions but reading).

Here I start sc_serv:
/path/to/sc_serv /path/to/config &

Now, it's in the background, and after the first connect, the server crashes, no output to logfile (if set), but "Segmentation fault" on terminal!

The config:
Port: 8000
Pass: nomatter
; Banfile = sc_serv.ban
; Logfile = sc_serv.log

Please take a look, Banfile is commented!
After I switched back to my homedir, the server didn't crash anymore!
So I cd back to /root and there:
touch sc_serv.ban
touch sc_serv.rip

and starting the server. Now the server runs perfectly!


OK, thats the punchline:
Even if you don't process the banfile in your config, you need the permission to write the file in the directory where you start the server (in my case /root).

It *IS* a bug of shoutcast, however, you may use my workaround!
