Fedora Networking :: Mount Using Only IP - Installing OpenMPI
Mar 9, 2009
While installing openmpi it is requried to mount using following command:mount nfs yourmachineIP /mnt/nfs but executing this command gives following error: mount: directory to mount not in host:dir format although i m able to mount a folder using mount �t nfs yourmachineIP:/dir /mnt/nfs where /dir is specified in /etc/exports. Is it possible 2 mount only using IP? in that case what should be mentioned in /etc/exports?

I find problem when run MPICH2 (also Openmpi) on the newest issue of centos-5.6 prerevious I tried MPICH2 on Centos 4, there is no such problem. My procedure is as follows: I built a Bewolf Cluster between 6 nodes of our serve (HP
Proliant G460 G7), and installed the MPICH2 on one node (assuming at /mirror), ./configure --prefix=/mirror/mpich CC=icc CXX=icpc F77=ifort FC=ifort make 2>&1 make install 2>&1
using NFS, the directory of /mirror was successfully exported to the rest of 5 nodes. Now as I test the mpirun, it runs very well on a single node, however it hangs across multiple nodes. Also I have built the passphraseless ssh-keys connection between each other. Now the problem is that even I use the mpd, boot the nodes(those nodes are in the list, and there is no warning during the booting), however when I run the mpirun, whatever how much n (-n X)I set, all the process will be run at the local nodes. I am not sure what are blocking the data exchange between the nodes, by the way, I have set the iptables to accept then data.

I am taking a parallel computing course at school and will be required to write programs using MPI soon. All of the school servers have Lam/MPI installed on them but I can only find OpenMPI slackbuild scripts. If I install OpenMPI on my computer and do my development on my own machine, will I have much trouble when it's compiled/run on the school servers?

I'm trying to get OpenMPI (a parallel programming library) working on my home system. I have just two machines on it now, t61 and quad, connected through a router. (Which is also connected to cable modem for internet.) I can ssh between the machnes, mount directories with NFS, etc. However, I just can't get the OpenMPI to run. The OpenMPI message board suggested that the most probable cause is that the firewall is blocking TCP. I don't know how to tell if that's the problem, and can't find any manual for the SuSE firewall, while the various Wikis &c that pop up in a search don't provide any information that addresses my problem.

I have installed OpenMPI from ubuntu repository. However some users need openMp. The problem is I didn't find that in ubuntu repository. Where can I found deb packages? If I must install from source, then is there any conflict between openMp and openMPI?

I've installed openMPI-1.4.1 on my laptop and I'm trying to compile some fortran code I've written using MPI. I downloaded the openMPI-1.4.1 file from the openMPI website and used the shell script they provide to install it. This is the shell script:
shell$ cd openmpi-1.4.1
shell$ ./configure --prefix=/usr/local
shell$ make all install
There was an additional line extracting the tar file, but I did this by hand. The first time I ran this script there was an error on the final stage saying that a directory couldn't be created because of lack of permission. I decided to run the script again this time as a sudo.
Having run the script again everything appeared to install properly, however when I went to compile some fairly simple code I got a message saying that the compiler couldn't find MPI. I was using this command: gfortran messages.f90 -o messages I looked on the openMPI website where it recommends compiling with a compiler called mpif. However when I type mpif messages.f90 -o messages I get an error message saying mpif isn't a recognized command......

What could block access from Fedora to just one Windows XP system without blocking access to or from other Windows systems on the network? I have a working Windows network with six computers and one network-attached-storage. Two of the computers (MARTIN and NANCY) are Windows XP, the rest are older. I set up a Fedora laptop with Samba. The Fedora system can access the Internet (I'm using it to post this message). It can see all the Windows systems, and it can open all of them except MARTIN. The firewall on MARTIN is turned off.
I go to Places, Network, and I see nine icons: the Fedora system, seven Windows systems and one for Windows Network. If I double-click on the MARTIN icon I get a message window that says "Unable to mount location" and "Failed to retrieve share list from server". If I double-click on any of the other Windows icons, including NANCY, a new window opens showing the shares on that system. Similar results with smbclient. It shows the shares for all systems except MARTIN. For MARTIN it says "Connection to MARTIN failed (Error NT_STATUS_UNSUCCESSFUL)."
The other Windows computers on the network can open the shares on MARTIN with no problem. The network is partly wired and partly wireless. The wireless network is secured with WEP. The Fedora laptop is (as you might expect) wireless. The Fedora laptop is an emachines E520 and both Windows XP machines are custom-built tower systems. I don't think that information is relevant but I mention it anyway. What should I look for?

I recently installed Fedora 12 + KDE on my laptop. I also have a media PC which I have connected to my TV. It has an external HD connected to which I am trying to mount on my laptop. It is connected to two other PCs all running Windows 7, part of a workgroup that only requires a password with no user log in. These PCs are working OK but I cant mount the shared drive on my Fedora laptop. I have tried the "Add Network Place" wizard which didnt work. Tried using the host IP rather than the host name. This got me to a user authentication screen which prompted me for a username and password.
As I mentioned before, the only user authentication required to connect to it should be that the device should be within the same workgroup and use the password. Tried using the workgroup name as the username which didnt work, neither did using the PCs usual log in. Eventually I gave up on the wizard and attempted to mount it from the command line using the following command.

I am unable to mount Windows shares on Fedora 12. From Nautilus, I can navigate to the shares, but when I attempt to open one I get a dialog "Password required for share ... on ..." asking for username (prepopulated with my username), domain (prepopulated with MYGROUP) and password. I have the same username on the Windows box, but when I enter the password and click Connect, the dialog just pops up again. I'm not sure what "domain" is, tried with my Windows workgroup name, no good. If I blank out either username or domain, the Connect button is disabled.
I tried using the mount command:mount -t cifs //192.168.0.2/... /tmp/mnt -o username=adrian,password=...,iocharset=utf8,file_m ode=0777,dir_mode=0777
That did work once, but now gives the useful error message:mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
I can run Windows instead on the client machine, and that gives me access to the shares, no problem.
I have libsmbclient-3.4.5-55.fc12.i686, but that was installed a month ago. I don't see any more recent changes to anything relating to the samba client. I've never had to enter a password to access Windows shares. Actually, it looks like the problem may be on the Windows side, although as far as I know, nothing has changed there. Using smbclient with debuglevel set high, I see failures with this error:SPNEGO login failed: NT_STATUS_REQUEST_NOT_ACCEPTED
Every now and again, I can connect to one or more shares, but after a few attempts, I can't connect to any more. Tried rebooting the Windows box, but that's had no effect. Oh, and "smbclient -L" shows domain as the host name of the windows box, but anonymous login (smbclient -L -N) shows domain as the workgroup name.

I've recently set up a fedora 13 machine to use as a media server, I've been able to get everything going except samba. I've installed a second hard drive which is mounted at /media/Core and works fine on the local filesystem. I can browse the share from my mac however when I connect I get this in the smb.log file

I have been trying to work out how to set up Fedora 15 to automatically mount an NFS share at boot time. I can mount the share interactively using 'mount -t nfs server:/usr/local /usr/local'. When I put the entry in /etc/fstab, it stops the machine booting. It tries to give me a shell ('Enter root password for shell or press Control-D to exit') or something close to that. However, I cannot enter the maintenance mode, it hangs. Same thing with pressing control-D, it hangs and doesn't get any further.
I rescued the system by booting off a CD, mounting root, and removing the nfs entry from fstab. After that it booted fine. The entry I had in the fstab is: nfsserver:usr/local /usr/localnfsro,hard,bg,intr,comment=systemd.automount0 0
I put the 'comment=systemd.automount' entry in because of some related searches I did in forums.

I have a Dell Inspiron 1720 running Ubuntu v10.04 with a wireless card.My desktop is a Dell Optiflex running WinXP.The desktop is connected via ethernet cable to a Linksys wireless router. Certain folders on the desktop are set for sharing. Up until early last week I was able to access the desktop folders from the laptop with no issues.Suddenly I am now getting this error "Unable to mount location Failed to mount Windows share" whenever I try to access the desktop folders from the laptop.I suspect an upgrade is the culprit, but not sure.

i'm trying to connect to the three other machines in my house but am having quite a hard time doing so. i've never had a problem in the past with ubuntu, but, with 9.1 and windows 7, things have gotten a bit harder. i'm running 9.1 and my roommates are running windows 7. i've installed, set up and configured samba and i can see the computers on my network, but any time i try to access either of the drives, it says unable to mount location: failed to mount windows share.

As root, I can mount the /home directory from my desktop to my laptop which uses wireless. However, when I logout the mount disappears. That is, I mount the directory, check it is mounted, then I logout, log back in as root, the mount is now not there. How do I make the mount persistent, always there?
I want the mount to persist so that the two ordinary users on my small household network can access the same files whichever computer they use.
It appears that this may be because the wireless link disappears when I log out. Both machines are using Fedora 10. A persistent mount used to work using Febora 8, but maybe some settings I am not aware of have changed.

I use F10 at home and while away from work on my laptop. Recently I could get the VPN sorted out ( I can now connect to the vpn (ppp0) server at work from home or anywhere else). I am trying to mount a windows folder that is on the work server on my F10 box at home through the VPN connection that is first established.What I know about the windws server
servername
sharename
username
password
When I try this
sudo mount -t cifs //pxxxx/home/abcd /mnt/dir/ -o username=abcd,password=xxxx
I get this error
mount error: could not resolve address for pxxxx: Name or service not known
No ip address specified and hostname not found
I think the VPN connection is established successfully. I have a ppp0 connection under ifconfig with an IP address after vpn connection is established.In windows I just map the network drive (\pxxxxhome) username=abcd, password=xxxx and mount the folder as "abcd on pxxxxhome"

I am trying to share directories between two F12 machines on a local network with a router box doing DHCP because not all machines on all the time. Web access is fine and local ping and ssh works but telnet doesn't. I have never succeeded doing mounts. So I have been searching for things to fix the above and have just tried rpcinfo. If I do this :
rpcinfo -p 192.168.2.2 it gives rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host. Does that suggest that actually there is an installation problem? So I tried "yum provides portmapper" and that gives "No Matches found".

I have edited my /etc/fstab file in order to have it automatically mount a windows network share at startup.
The problem is, that it isn't really working during startup. After I log in, in order to make it mount I have to open the terminal and enter "mount -a".
The following is my fstab file:
Code:
I suspect this has something to do with my laptop not having made a network connection when the entries are mounted, but I'm not sure. How would I go about finding out about any errors?

I have a bootable utility toolset that I put together with Fedora 14, one of its primary functions is to map a user designated share via script and access information from it. The command that I used, that functioned perfectly, in Fedora 14 was:
Code:
sudo mount -t cifs -o user=provided.account.name //file-server.mydomain.com/share/images /mnt/source

I am trying to access a DVD mounted on a machine running Fedora12 (192.168.0.105). I thought this should be possible with NFS, but the above error message is what I keep getting, no matter what I try.
Here is my mount command:
Code:
mount 192.168.0.105:/mnt/dvd -t nfs /tmp/scaleo
The Fedora 12 machine has the NFS server running, and the corresponding entry in /etc/exports is
Code:
/mnt/dvd *(ro)
I thought this might be a firewall problem, but it persists even if I turn firewalls off on both machines (client as well as server.) Also, doing
Code:
ssh 192.168.0.105
is OK, so what is wrong with the route?

mount 192.168.0.105:/mnt/dvd -t nfs4 /tmp/scaleo
and it seems the mount succeeded. So, instead of nfs, one must write nfs4?

I have been trying to share folders from my main PC which is running Ubuntu 10.04. I have been able to figure out Samba enough to get my a couple of folders shared, but I have been unable to share any folders which are on my external harddrive. After entering the path in my smb.conf file they appear on the network but I am unable to navigate to them. When trying to navigate to them through the network folder on the pc they are actually connected to I get an "Unable to mount location: Failed to mount windows share" dialog box. On the windows pc I am trying to share with I get, "Windows cannot acces \Josh-Desktop
ame of folder"
My smb.conf file looks like this:
That folders I cannot access are Music and Videos.

We are using spare parts (Socket 775 Biostar motherboard, OCZ 500wat PSU) to build a computer that will just be another system in the house. I want this system to be running Folding@Home, and the F@H SMP client for Linux is much less of a headache than its Windows couterpart, so I would like this computer to run Fedora. My dad loves networking, and knows how to do it in XP / Vista, so he has always opposed my frequent use of Linux. There are ways of accessing Windows shared folders from Linux, but that I haven't figured it out yet. I want to access Windows shared folders from my Fedora 10. I don't know how to go about doing this, can anyone point me in the right direction? Do I have to install anything special? I can go to Places, and then Network (in Gnome) and I see "Windows Network", but when I click it, I get "Unable to mount location Failed to retrieve share list from server"

Our office just switched from CentOs to Fedora and I'm trying to get everything set up. Everything is working so farbut im having a problem with my mounted cifs drives. They mount ok, I made directories in /mnt where the drives are readable and accessible. I'm only missing the shortcuts to the mounted drives in nautilus and on the desktop. I've checked the gconf editor and the volumes should be visible.Is there an extra option i have to add in the fstab line to get the shortcuts or something like that?

I have Fedora 12 (Fedora-12-i686-Live.iso) installed and booting in a VMWare workstation (version 6.5.3). I am able to login as the LiveUser.
I need information on how to access the drives on my host which is WindowsXP. My C: on the host is shared, and my network adapter for the VM is "NAT".
The only directory listed in my /mnt directory is "live".
My Fedora enviornment is "bare bones". There is nothing installed except for the original files from the "iso" loading procedure.
I also have been unable to get the VMWare tools installed, and I don't know if this is related. I don't mind bypassing this if this isn't required. My only desire right now is to access my C:

I am trying to mount a directory from my server onto my wireless laptop. The directory mounts successfully if I am already logged into the laptop with another account first but if I log on initially with the user who requires the mount the mount fails. I suspect the mount is taking place before my network connection is up, is it possible therefore, to delay the mount in fstab until the network is fully connected?

My network has several machines on it. They are all connected to a single router. Two of the machines are running Windows Vista, one Windows XP and one Fedora 11. When I go to places.network, I see an icon that says Windows Network. If I click on it, I get the message: Unable to mount location, Failed to retrieve share list from server. When I had Ubuntu running on this machine, I had no problem seeing and connecting to the Windows Vista machine.
