General :: VM Server Can't Attach To The NFS Share?
Aug 4, 2011
I have a question about NFS and CentOS 6.0. Here is the environment: Server running VMware's esxi 3.5 (Fully patched) 10.1.1.50 Server running CentOS 5.5 with NFS. 10.1.1.51 With the systems in the above config everything is working fine. Install a new hard drive in the CentOS server and install CentOS 6.0. Use the same IP 10.1.1.51. Configure NFS, the VM server can't attach to the NFS share.
Here is the config of the NFS server:
Firewall Disabled
SELinux Disabled
NFS installed and running.
NFS-Utils installed.
Contents of /etc/exports
[Code]...
I have confirmed I can telnet to the ports listed. Any clue why the setup with CentOS 6.0 doesn't work? Is this a NFS4 vs. NFS3 thing? Is there a way to force CentOS to use NFS3? I am pretty sure the CentOS 5.5 server is using NFS4.

Today I've found several attempt to access the following url on my website: [URL] After googleing a bit it seems that in some cases, using this attack, the bag guy is able to change the code in some of your files. it also seems to affect only a certain version of oScommerce. I don't use oScommerce, so I do believe that I'm on the safe side, but it's not the first time that I see some similar attempt of attack on my website. So to protect my self I was wondering if using .htaccess restriction would be enough?
Code:
########## Begin - Rewrite rules to block out some common exploits
#
RewriteEngine on
Options +FollowSymLinks
[code]....
But I do think that these rewrite string are more specificity write to protect oScommerce site. how to protect my web site from such attach and similar?

If I start a process with nohup:
nohup WHATEVER &
then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.

I am trying to set-up a script that will go to the folder and attach all files from that folder to the email without having to specify name for each attached file.
Below script requires exact name of the file and then puts file context into the emails body.

Recently installed debian lenny.Running very well.WM: ratpoison.Suddenly, today, the internet runs much slower.ONLY ON THIS MACHINE - the parallel windows machine, off of which I was successfully weaning myself, is not having this problem, so it's neither the router nor the actual internet connection.Specifically: I can't attach a document in yahoo mail.I tried it in iceweasel, same problem, so it's not the browser.I piped the output of "top" for a minute or so to a text file, which I'm attaching.

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'm experimenting with CentOS DS and have a question.Is it possible to attach windows xp machines to a CentOS DS? If so, how?!I think I've skimmed most of the documentation out there. Did I miss something? Is this not what the DS was designed to do?

My Goal: I'm migrating data from the OpenSUSE server to the 2008 Storage Server. The idea is that all the data will reside on the 2008 Storage Server in an NFS share which will be mounted to the OpenSUSE server in the same location in which the data sat in initially.
I'd like this to be completely transparent to everyday use -- all programs designed to interact from a few other servers / computers will still work without modification, and, more importantly, all file permissions can remain the same. As far as I've seen the SMB mounting doesn't full preserve the *nix file permissions. I'm hoping the NFS mount will, but please tell me if I'm wrong. SMB is so much more straight-forward and already working. I should also note speed is a giant plus for NFS.
The Players:
Windows Server 2003 - The Active Directory server
Windows Storage Server 2008 - The new file server
OpenSUSE 10.3 - The workhorse server
I have no control over the operating system choice. I have no control over the AD server. I have limited, intermittent access to the person who does have full control of the AD server. I have full control over the file server and the workhorse server.
What I've done: The Storage Server is running Services for Network File System (NFS). It has a 6.5ish TB RAID partition configured for NFS and Samba/CIFS sharing which is used for the data storage. The Samba/CIFS share is mountable and accessible, but I haven't found a way to maintain proper user permissions on the files. When I connect the owner and group for every file is root:root, which led me to NFS in hopes this would fix the problem.
The AD server admin has installed Services for Unix, and we imported the OpenSUSE passwd and group file. Either this didn't work, or it take a bit more configuration. Tomorrow morning we're going to take a deeper look into the SFU configuration with the AD.
Right now I can mount the NFS share on the OpenSUSE under the root account:
Command results truncated to what I think is relevant info. Ask if you need more.
Code:
My Problems:
I'm hoping the "Permission denied" error is solely because the UID and GID mappings are incorrect. I have, however, tried to create an NFS share with full permissions to "Everyone" and anonymous access, and I get the same results.
Also I've run into another roadblock. Why do non-root accounts fail to execute the mount /mnt/datadir command?
Code:
AFAIK 1048 is not a restricted port, so regular users should have access to bind to the port. I also have a Gentoo machine where regular users are allowed to execute the command. The 'mount' command shows that the NFS share was mounted with the username executing the command too.
Server NFS Config:
Code:
The following are the settings on localhost
The above was written yesterday and not posted in hopes I could solve the problem this morning. I failed.
Update: The domain admin installed an NIS server on the AD server. I installed an NIS server on a Gentoo Linux box. They weren't able to communicate. The Linux box thought the Windows NIS service wasn't running and Windows couldn't find the Linux machine. NIS led to a dead-end right about there. I also tried to manually link the user accounts to UNIX UIDs via the AD user properties window to no avail.

I am trying to mount a shared drive on a Windows Server 2008 machine using a Linux machine (Fedora 13). I try mounting by
# mount //HOSTNAME/SHARENAME /mnt/FOLDER
and I get mount error(13): Permission denied.
I have tried other options like # mount -t nfs //HOSTNAME/SHARENAME /mnt/FOLDER -o username=USERNAME and the same thing with different filesystem types (ntfs, smbfs, cifs).
I have:
checked all firewall configurations.
verified security/sharing settings
for the drive
verified registry keys under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNfsSvrParameters
verified NFS server is running
I am familiar with Windows Server 2008 but I have never configured a system from scratch on my own. The computer I'm using used to have Windows 7 for sharing folders to a Linux server. I have just switched to Server 2008 and have not been able to mount anymore.
One thing that I think is that I tried setting up an identity mapping solution; however, I do not have a domain controller setup. I am still functioning on a workgroup.

I have my local computer, and server.
I log into server, and mount my local computer (folder) via sshfs.
Create .rar backup archive direct to sshfs remote folder.
After copy, close my ssh sessions.
And use my streamer to backup files stored by server.
I'm wondering, is there any way to share streamer /dev/st0 via ssh session ?
how can i start backup direct to (remote) -> root@server/dev/st0

I'm trying to mount a Windows Server 2003 share in Fedora 13. With Fedora 8 and with RHEL 5.5 this works properly, but not with Fedora 13.
The mount point I'm using is /usr/eg
The symptoms are: Nautilus (the file browser) does not display the mount in the places or tree as a mounted drive. Using the file broser I can browse under file system down to the files on the server Programs cannot find the files under /usr/eg ie the files on the server.
Here is my fstab entry:
//192.168.1.40/eg /usr/eg cifs auto,user=<user>,password=<password>,rw,uid=500,gid=500,file_mode=0774._netdev 0 0

I am having issues mounting a share on a Windows 2008 Server from all of our Redhat 4 machines. I am trying to back up files before wiping and upgrading them to 5. I will try and post as much information that I gathered after trying different things. I am a newer hire for this network and a Linux newbie.
The scenario is this:
1. Windows 2008 Active Directory.
2. Redhat Enterprise 4 machines
I have root access and I tried entering at the terminal:
" smbclient -L "servername" -U "username"
get the "password" prompt I enter my password and get:
"session setup failed: NT_STATUS_ACCOUNT_LOCKED_OUT."
I check event viewer on the 2008 box and last week was seeing:
Event ID: 4625
Keywords: Audit Failure
etc, etc
"Account for which Logon failed:
Security ID: NULL SID
Account name: anonymous
Account Domain:MYGROUP
Failure Information:
Failure Reason: Uknown user name or bad password
etc, etc
Now the last couple of days the audit failures have not shown up on the 2008 Server box even though I attempted to log in.
The end users used to just use Konquerer smb://"servername"/"share" and it worked but for some reason starting last week this no longer works. Nothing was changed that I know of, this network is in a sealed classified environment with no external access. All additions to the network are monitored and no unapproved software is installed. The lab is in a vault type environment and only a few people know the combination and alarm pass codes so no chance of somebody adding stuff without me knowing it.
I would think with the locked out message it was an issue with my user account but that works fine on the Windows side so I tried my Linux credentials with no success when trying to mount the directory.
Is there something anybody can suggest Linux or Windows side to check? No user accounts work connecting to the Windows share.
p.s. I am aware the above command is only to see the Windows shares but i get the same thing when I just try and mount using CIFS or SMBFS.

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 have 30 systems in a LAN . My users need to login as domain user from their XP clients and store their files in the Linux server. They should not be allowed to store in local machine and also should be granted a particular size of space in server.
what are the procedures to be done in linux server and
just like in windows we access shared files in by typing in run command
\192.168.0.1 is there a provision to view shared files from xp to Linux

Two users on both Ubuntu server and Windows 7. Both users admins on Windows. Used SWAT to set up Samba. Printer is local to Ubuntu server. User A can access both file share and printer on Ubuntu server from Windows. User B can access the file share but can only see the printer, not use it. Have looked everywhere I can think of to find out why one user has access and the other doesn't on both Windows side and Ubuntu side. As far as I can tell, they are set up the same. Can anyone provide some direction on what I should look at to find out what might be preventing User B from being authorized to use the printer on Ubuntu?

Have an NFS Server running on RHEL 5.4 with the following setup/export/home is mounted from a SAN and shared out (no problems there)In oneome directory I have recently mounted another partition (e.g. /export/home/user/foo) This directory is also shared via NFS.When logging into an NFS Client you can access /home/user as expected. If you CD into foo there are no errors, you can even read/write files there.On the NFS Server those files can only be seen by umounting /export/home/user/foo.The idea is for 'footo contain files are churned at a very high rate and that this partition will not be replicated offsite

I have a LAN of about 70 computers that I would like to share media files between. I have gotten to the point with Samba that I can view the files without a username/password from client PC's. I would like to make all the folders read only except for one which will be writable for everyone. The thing that I am having a hard time with is allowing a couple of administrators (on Windows 7 machines) read/write access for all files/folders. I am completely new to Ubuntu and Samba so please make explanations thorough. Here is /etc/samba/smb.conf file:

If I attach an NTFS drive to opensuse 11.3, will the OS see the drive and the files?
My goal:
I wanted to install OpenSuSE and add VMware Server 2.02 on top of it. I have a few hard drives that are NTFS. I need for my Windows virtual machines to see those hard drives. So in order for that to happen, the host OS would have to see the hard drives as well.
