hello please anybody solve my problem...I configured samba server on my machine RHEL5
but it is connecting with window..but when i connecting linux to linux with this command <mount //10.0.0.5/myshare /mnt -o mary> it is giving the error ths..
mount //10.0.0.254/myshare /mnt -o mary
Password:
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
which permission i`ll have to give...pls solve this...

You will want to read the manpage for mount.cifs as the error message indicates. Mary isn't an option.
Maybe you meant: -o username=mary.

It would be better to have a credentials file saved in a location that not everyone can read. For example ~/.credentials. the file should contain:
username=<username>
password=<password>

Add a domain= line if you need it. Then the option would be "cred=~/.credentials"

The reason to do this is that the /etc/password file is globally readable. You don't want a username and password in a file that everyone can read.

yes mary is user and i wrote in /etc/samba/smb.conf this

[myshare]
comment = hello
path = /data
valid users = mary fred
host deny = 10.0.0.3
public = no
writable = yes
printable = no
create mask = 0765
