Cp from Linux to CIFS (windows) share mount is very slow

Just to map a network share directory you would use this command:

net use \\Server\ShareName\Directory

This mapping would:

• not be persistent
• would have to be established and authenticated at user login
• you would access the share using the UNC path, and not a local drive letter

If you want to access the network share through a location on your local C: drive, you'll want to set up a symbolic link:

mklink /d  C:\Folder\ShareName \\Server\ShareName\Directory

Now when you navigate to C:\Folder\Share you'll see the contents of \\\Server\Sharename\Directory. You'll still need to provide authentication for the resource with something like net use (or just be logged into a domain account on a domain system that has access) otherwise the link will probably error out angrily.

There should be an /etc/auto.smb already, use that, and add the following line to /etc/auto.master:

/cifs   /etc/auto.smb --timeout=60

Now all cifs shares will show up under /cifs:

ls /cifs/<server>

will show all the shares available. You might want to put some options in /etc/auto.smb to mount with specific modes. I have a auto.smb that I found out there somewhere and modified to do exactly that:

#!/bin/bash
# $Id: auto.smb,v 1.3 2005/04/05 13:02:09 raven Exp $
# This file must be executable to work! chmod 755!

key="$1"
credfile="/etc/auto.smb.$key"

opts="-fstype=cifs,file_mode=0644,dir_mode=0755,uid=eng,gid=eng"
smbclientopts=""

for P in /bin /sbin /usr/bin /usr/sbin
do
    if [ -x $P/smbclient ]
    then
        SMBCLIENT=$P/smbclient
        break
    fi
done

[ -x $SMBCLIENT ] || exit 1

if [ -e "$credfile" ]
then
    opts=$opts",credentials=$credfile"
    smbclientopts="-A "$credfile
else
    smbclientopts="-N"
fi

$SMBCLIENT $smbclientopts -gNL $key 2>/dev/null| awk -v key="$key" -v opts="$opts" -F'|' -- '
    BEGIN   { ORS=""; first=1 }
    /Disk/  {
              if (first)
                  print opts; first=0
              dir = $2
              loc = $2
              # Enclose mount dir and location in quotes
              # Double quote "$" in location as it is special
              gsub(/\$$/, "\\$", loc);
              print " \\\n\t \"/" dir "\"", "\"://" key "/" loc "\""
            }
    END     { if (!first) print "\n"; else exit 1 }
'

This will do what you want. I've used it myself.
