Hi,

Can you send following information?

* backtrace from the lighttpd core after lighttpd has crashed.
* complete glusterfs logfile as an attachment.

Also, mod_glusterfs is listed at the end in server.modules. Can you move it to top and retry?

regards,

After that lighttpd is died.


Lighttpd version 1.4.19.

Help please with this problem.

Hi,

These are warning messages. Even though it cannot bind to any port <= 1024, lighttpd goes ahead and binds to a non privileged port. But since client is bound to non-privileged port, the address based authentication do not accept the client. Hence client should be using login based authentication. More details about authentication methods can be found in <srcdir>/docs/authentication.txt

regards,

I solved this error, I add one string to mod_glusterfs.h:

But mod_glusterfs didn't work still. In lighttpd mod_glusterfs log I saw:

Lighttpd is runing with owner user www-data and www-data can't create socket with port less than 1024.

How I can solve this problem?

Hello!

I build glusterfs and lighttpd 1.4.19 with mod_glusterfs. When I try to start lighttpd, I  get this error:

2009-02-13 14:42:13: (plugin.c.165) dlopen() failed for: /usr/lib/lighttpd/mod_glusterfs.so /usr/lib/lighttpd/mod_glusterfs.so: undefined symbol: CALLOC
2009-02-13 14:42:13: (server.c.621) loading plugins finally failed

Help me please with strange error.
