We have a homegrown process that runs on a windows box and produces a csv file. We mount the directory these are output to using autofs/cifs and then process them using a program on our linux database servers.
Is there a way from linux, looking at the cifs share, to tell if the target file is currently in use by a process on the windows box? We are having issues where an incomplete file is being processed occasionally.
I followed this howto in order to mount CIFS shares on demand. This works great, however, this guide suggests leaving my network passwords unencrypted on the disk. This is a very bad security practice, as the passwords can be easly retrieved by booting the computer using a different OS.
I was looking for a way to secure things up, so I came up with this solution: Instead of storing the passwords plain text on the disk, I store them in a tar file encrypted using GPG. When I boot my system, I open this file to a directory in /dev/shm, and order AutoFS to retrieve the passwords from there.
This does the trick, but I presume this solution is not that secure, since /dev/shm content can be written to the swap partition. Is there any other solution which is a better security practice? Maybe using some sort of keyring service?
I am trying to image about 30 laptops with WinXP, and I am using Clonezilla and DRBL for the task. We will start migration to Win7 starting Q4, so for now we are still using XP. I used a Clonezilla live USB to capture a standardized image to a CIFS/SAMBA share on the enterprise file server. The file server does not support NFS. To deploy the image, I used Virtualbox to build a VM with Centos 5.5 and then later Ubuntu 10.10. I mounted the CIFS share to /home/partimag but I found that I cannot share this CIFS mount out as NFS so I was unable to deploy the image with the image still residing on the CIFS; I had to copy the image to the VM's local drive.
Now using the DRBL live distribution, which is Debian based, I was able to obtain the image from a CIFS share and then share it out to the clients to be imaged as NFS (I think). I was able to use the DRBL live for some older computers, but since that hasn't been updated in nearly 2 years, I think it's missing some device drivers for my newer machines so it doesn't work on them -- this is why I looked at using CentOS and Ubuntu. To mount the CIFS shares, I'm using the following command:
mount -t cifs -o user@domain //share_ip_addr/share_name/folder /home/mount_point
Do I need to do something different to enable the mounted CIFS share to be shared out as a NFS share so that the clients to be imaged can see the contents from the CIFS share as a NFS share? The below image depicts my setup. The workstation has two NICs. The 10 network is the enterprise network and the 192 network is for DRBL imaging only. DRBL/Clonezilla does PXE boot and leases DHCP for the laptops. The laptops are shielded from the enterprise LAN; I am not doing any kind of NAT on on the server. The Linux VM is built with dual NICs and are set to bridged mode so they appear to be a separate NIC from the VM host on the network even though they going into the same port on the wall. [URL]
I've been trying for a while mounting a EMC NAS share on linux. As far as I know the NAS share behaves just like a regular windows share, so the mount process should be very similar. On the NAS server, the disc "Disc1" is shared, and I need to mount a sub-subfolder of that share. This is my line in /etc/fstab:
Code:
//windows_box/Disc1$/folder1/subfolder /var/tmp/mount_test cifs defaults,acl,soft,uid=srvadm,gid=adm,umask=0027,file_mode=0600,dir_mode=0700,credentials=/root/cred.txt,sec=ntlmv2 0 0
When mounting the share, this is what happens:
Code:
[root@server1 tmp]# ll
total 8
drwxr-xr-x 2 root root 4096 Jun 18 10:39 mount_test
[code]....
In the console (i.e. bash), the "mount_test" word on the last line has a red background. When I issue "umount mount_test", everything is back to normal.
We recently moved to a new home and I am trying to get my home file/print server set up again. Thanks to swerdna's excellent website, I got my server box (just upgraded from 11.0 to 11.2) running Samba and serving my shares over the network, and my "client" machines can access them without a problem.However, I'm not having much luck setting up CIFS mounts on my Linux desktop. I have my all-purpose user added to the Samba auth list (via smbpasswd), and configured my client as swerdna's howto's specify, and I can access the files just find. However, when I try to mount the shares with this command:
Code:
mount -t cifs -o username=klein,password=klein //192.168.1.70/sharedmedia /home/zak/SharedMedia/
I get the following error:

Q: How do I mount a CIFS share so that my user stevej has all rights to it?
Summary: I can mount the share as root.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej
Using Dolphin in Super-User mode, I can copy files and directories from the share to itself with no errors. Using Dolphin in Normal-user mode. I get the failure "Could not change permissions for...". The file is copied, but its owner,timestamp and permissions are wrong. If a subdirectory is involved, the copy aborts.
Using Windows XP I can copy files and directories from the share to itself with no errors.
Testing: If I mount with uid and gid, then my normal user can not access the share.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej uid=stevej gid=users
[code]...
Synology DS211 - There are 2 users on it. One of which is stevej and the other is julie. Rights RWX are applied to the users and the group called users. All files have stevej as the owner and users as the group with RWX Opensuse 11.4 - There are 2 pc's. One is run as stevej. The other pc runs as julie Windows 2000 - Runs as stevej and maps to the share as stevej.
Works as expected Windows XP - Runs as julie and maps the the share as julie. Works as expected Ultimately, I want the shares to automount at boot, or login and give the user full access. I have been to Swerdna's page and done as much as I can, but still no luck.

Greetings. I cannot get autofs to mount a CIFS share. I tried to follow http://wiki.centos.org/TipsAndTricks/WindowsShares .
a) Windows share is \server-01Share
b) user: backups, password: backups has READ access to this share
c) mount -t cifs //server-01/Share -o username=backups,password=backups /mnt/server-01 WORKS FINE
d) Note that most default Centos services (including all NFS stuff has been disabled on boot, if this makes any difference)
e) /etc/auto.master:
left default configuration including (should these be changed or rem'd out?:)
/misc /etc/auto.misc
/net -hosts
#added at end of file
/test/auto.test
f) created /test and /etc/auto.test
#auto.test
#note I tried rw and just r
test -fstype=cifs,rw,noperm,user=backups,pass=backups ://server-01/Share
g) ls /test = nothing
e) message log contains automount:..."lookup_read_master: lookup(nisplus): couldn't locate nis+ table auto.master"
There are a couple of way to mount Samba shares, but I prefer using "autofs" which can mount them on the fly. Use the autofs daemon to have shares automatically mounted on demand. The netfs service (installed by default in Fedora) is not a daemon and can only mount shares on boot, (it can't mount them on demand).
* Install the autofs package:
Code:
yum install autofs * Edit /etc/auto.master (the master map file), and comment out all lines (with #). This avoids conflicts with the CDROM (which is handled by Gnome), etc. Save the file. * Create a new file /etc/auto.cifs, with the contents of:
Code:
#!/bin/bash
# $Id$

I've got a Fedora 10 server with a simple read-only samba share.I'm able to mount and browse the share from a Fedora 12 client, but all directories appear as empty--and I can see on the server that they contain many files. This happens whether I browse using smbclient, or mount using mount.cifs.I've got smb/nmb ports enabled on both the client and server. File permissions on the server look right.The server smb.conf setup:

I have a little problem with my RHEL5.5 IA64. I mounted a Windows directory with 'mount -t cifs'. After a little while someone else mounted the same windows directory in the same mountpoint. The output from 'mount -v' shows me that the same directory is mounted twice in the same mountpoints. I cannot unmount it, not even with the force option. The error is "Device or resource busy". There are no open files in the shared directory and no one using the directory or subdirectories.

View 7 Replies View RelatedI'm trying to mount some CIFS shares (NetApp) to my Ubuntu 11.04 desktop (64-bit).I am mounting it as a domain user with admin rights and full control over the share.ter mounting it as root, all the files are owned by root and I can't modify them from my non-root user.Here is how I am mounting the share:
mount -t cifs -o domain=example,username=example-user,password=mypassword //myfiler.example.com/myshare$/mydir /mnt/myshare/
This share is a qtree under a volume with security type set to NTFS. (Although I have also tried security type = Mixed) We don't configure user-level access to shares on the filer, we create directories and lay down permissions on those from the Windows side. (Although I have tried explicitly adding my domain user to the access list for the share)
Using SUSE 11 with Gnome. I mounted a CIFS share from a Windows server as /mnt/win. With the file browser, I can browse to file system/mnt/win and then the files and folders of the Windows share come up fine and I can open them. When I use the file browser to browse to network, the server hosting this share is listed. Then I browse to that server and it lists no shares (nothing at all). I can't go any further than the server. Is there a separate authentication necessary for the file browser to see this share from the network place?

I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.

Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.
this has happened in different distros, so far i have tried slack, arch, and mint at work i have an xp box with a shared folder i created. on my linux box i setup fstab as follows
Code:
//winxp/temp$ /home/user/temp cifs rw,uid=1000,gid=1000,credentials=/home/user/.creds 0 0
this gets mounted correctly and i can read/write the shared folder at home i have a win7 box that i create a share on and use the exact same code in fstab, but it wont mount the share. i get something like permission denied or access denied is there a difference in how winxp and win7 share folders? my usernames on the linux boxes match those of my windows boxes at each location. i have given my win accounts full access and control over the win shares.

I have a server, with a static IP of 192.168.1.17, that is running Ubuntu lucid sever edition and that exports some shares per NFS. Here is its /etc/exports:

how to make autofa5 work [with NFS4] using [in]direct mapping but no joy so far. Firsty, this the "/etc/exports" on my NFS4 server (CentOS 5.6):

/media/exPort htpc(ro,sync,no_subtree_check,no_root_squash,fsid=0)
/media/exPort/mMusic htpc(ro,sync,no_subtree_check,no_root_squash)
and this what I have in there:
Code:
[root@serv03 /]# ls -l /media/exPort/mMusic
total 16
drwxrwxr-x 11 databank lhome 4096 Jun 23 21:25 iTunes

drwxrwxr-x 3 databank lhome 4096 Aug 13 2010 Streaming Radio

But it doesn't work - neither it throws any errors in, nor does it mount the share. All I need is to mount "/mMusic" (i.e. /media/exPort/mMusic) as "serv03:/media/nMedia/mMusic" so that tree looks like this:
