Details:

I'm running the following configuration:

CentOS release 5.9 
neon-0.25.5-10.el5_4.1
davfs2-1.4.6-1.el5.rf

I'm testing davfs2 by connecting from a Centos server to dav_box_com. It works
fine as long as the server dav_box_com 
is accessible on the internet.

I asked my self what will happen if dav_box_com is not responding or if it's
responding but the remote share doesn't 
exist.

I went ahead and mapped dav_box_com on my /etc/hosts file to a non accessible
ip address and this is what happened:

1. When I try mounting using the following command line:

mount -t davfs dav_box_com/dav /mnt/box.com 

2. The server creates the following process:

[Centos]# ps -ef | grep mount
davfs2   17925     1  0 15:16 pts/0    00:00:00 /sbin/mount.davfs 
dav_box_com/dav /mnt/box_com -o rw

3. This process stays there indefinitely creating the following messages:

[Centos]# /sbin/mount.davfs: connection timed out two times;
trying one last time
[Centos]# /sbin/mount.davfs: connection timed out two times;
trying one last time
/sbin/mount.davfs: server temporarily unreachable;
mounting anyway


4. After 3 times trying the "df -h" will hang.


5. The davfs2 process stays hung:


[Centos]# ps -ef | grep mount
davfs2   17925     1  0 15:16 pts/0    00:00:00 /sbin/mount.davfs
dav_box_com/dav /mnt/box.com -o rw


I checked all the davfs2 config options and nothing is letting me change this
behavior.

How can I try to mount dav_box_com/dav in a way that if it doesn't mount
properly because is not finding the server or 
the share, it will completely terminate any davfs2 process ??

Thanks in advanced.
