Mount windows share

Question

I've just literally spent about 2 hours trying to simply mount a windows share on linux.

Mounting with cifs causes deadly hangs as discussed here.

So I tried to mount via nfs as discussed in this page.

I spent a few minutes searching the nfsshare program, until I realized I had to install Unix Services for Windows.

After downloading the huge file, I was deterred by Microsoft's scare tactic: this program has known compatibility issues, and the subsequent, setup has detected that a required System Service (TCP/IP) is not currently installed...

This is even after I enabled the Simple TCP/IP services from Turn Windows features on or off.

Running

$ sudo mount -t nfs 192.168.1.76:myshare ~/mount3/

on Debian unfailingly gives me:

mount.nfs: access denied by server while mounting 192.168.1.76:myshare

Even though I've opened read, write, full to everyone under windows for the share in question.

$ sudo showmount -e 192.168.1.76

usually gives me:

rpc mount export: RPC: Procedure unavailable

or sometimes:

clnt_create: RPC: Unable to send

I tried using freeNFS.exe, while still getting the access permission error on Debian. I tried using haneWIN, which fails with Failed to start PortMapper.

First, the command that you are using:

$ sudo mount -t nfs 192.168.1.76:myshare ~/mount3/

would be better as

$ sudo mount -t nfs //192.168.1.76/myshare  ~/mount3/ 

And do not forget when using ~/ to say whatever it is mounted on your root dir if using sudo it will consider you as "root" and not any user remember this! And another thing you should check are the permissions. Which users have access and what is the filesystem: NFS, NTFS, FAT16/32 ...?

Answer 2

Here is the workaround I've been using. I have not experienced any hangs so far, after mounting the cifs share for several hours. The idea is simply to periodically write to a file on the mounted subtree. This seems to maintain things alive on both ends.

#!/bin/sh -x

mountpoint="/home/user/mount3/mount"
if mount|grep ${mountpoint}; then
    echo lazy umounting
    sudo umount ${mountpoint} -l
fi

sudo pgkill.py -fq mount_cifs.sh 
rm ${mountpoint}/keepalive


echo mounting
sudo mount -t cifs -o username=$2,password=$3,dir_mode=0777,file_mode=0777 $1 ${mountpoint}

if test $? -eq 0;then
    echo mounted
else
    echo unable to mount
    exit
fi    
{ while true; do echo dummy > ${mountpoint}/keepalive; sleep 30; done }&

Answer 3

You could try the mountSMB or mountNFS scripts from here It should handle most of what you are trying to achieve

It will scan subnets and maintain a list of servers not available on your local subnet or through nmblookup
