Cant mount samba shares

pople · 08-28-2014, 05:07 PM

I have been trying to mount a samba share using:

Code:

sudo mount -t cifs -o username=bob //myserver/bob ./net

I can access the server on another windows machine using the same credentials and I can see and access the share using smbclient on my linux machine I just can't mount it. The error I recieve is:

Code:

 
Password for bob@//192.168.1.151/bob: 
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Anyone have thoughts on this? I am running Gentoo linux, samba 3.6.23 and kernel version 3.12.21-gentoo-r1 with CIFS support enabled.

Hi,

Error 13 is a pretty generic error for mount to throw back at you. It typically is caused by leaving a required parameter out, in most cases the domain, even if it's only a workgroup'd machine.

Try adding your domain to your command string. Use the machine name if you're not on a domain. Like:

Code:

mount.cifs -o username=bob,domain=<machine or domain> //myserver/bob ./net

If this still fails, there are many threads online describing this exact problem. It's likely you're facing something similar.

Well I do have a domain name server which I tried and I got the same error.

Code:

$ sudo mount -t cifs -v -o username=richard,domain=overnetwork.local //192.168.1.151/richard ./net
Password for richard@//192.168.1.151/richard: 
mount.cifs kernel mount options: ip=192.168.1.151,unc=\\192.168.1.151\richard,user=richard,,domain=overnetwork.local,pass=***
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Just for kicks I tried running the same thing on my laptop under localhost where the server was running and it worked. I was able to mount my shared folder. Kind of weird. It's is like cifs is having trouble sending the password or credentials

Code:

sudo mount -t cifs //localhost/richard ./net -o username=richard

Is there anything in the sudo log? Does it work from a root shell instead of sudo? Is there anything in the samba logs in /var/log/samba server-side?

Well there is a log file however it is empty. On boot my desktop kernel fails to load the cifs.ko module for some reason. Using modprobe to manually load cifs doesn't work either. I see:

Code:

* loading module cifs.ko
* failed to load cifs.ko

You know of any documentation that discuss why kernel modules failed to load? Or a way to tell the kernel to be more verbose?

dmesg will tell you more verbose information about modules failing to load. Also, when I said domain, I meant like NetBIOS name type domain. Try putting your samba machine's NetBIOS name for the domain parameter instead.

Ok. I was a little confused at first when you said domain name. I updated my smb.conf file using the "netbois name" variable and tried to mount again. My smb.conf file:

Code:

[global]
interfaces = lo enp0s25 wlp3s0
workgroup = WORKGROUP
socket options = TCP_NODELAY IPTOS_LOWDELAY
security = user
hosts allow = 192.168.1. 127.
log file = /var/log/samba/log.%m
max log size = 100 
netbios name = reolaptop

[homes]
valid users = %S
browseable = yes
writable = yes
read only = no

I still get an error when mounting.

Code:

sudo mount -t cifs //192.168.1.151/richard ./net -o username=richard,domain=reolaptop
Password for richard@//192.168.1.151/richard: 
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Running dmesg | grep 'cifs' did not return anything and I did not see anything related to it scrolling through (Somethimes I'm blind). I had been reading the readme for CIFS in the kernel source documentation and they have a section Misc /proc/fs/cifs Flags and Debug Info that I'm not quite sure how to implement. As a test tried changing some of the values in cifsFYI and SecurityFlags on my laptop where mount -t cifs worked util I changed them. I rebooted and things started working on my laptop again but desktop mount -t cifs is still broken. Not sure how anything is logged when the values can change on booting. I included the dmesg.log as an attachment if you have the time to look through it. Also, do you know of a way to pass debuging arguments to the cifs module such as modules_cifs_args="debug" in /etc/conf.d/modules?

Here's what's always worked for me. Username and password redacted but taken from the windows machine where the drive was installed from.

sudo mount -t cifs -o username=********,password=*******,uid=nick,rw,gid=nick //192.168.5.98/"goflex home public"
