Permanent ubuntu shares

from http://www.ubuntugeek.com/nfs-server-and-client-configuration-in-ubuntu.html

-------------------------------------------

On all machines:
sudo apt-get install portmap nfs-common nfs-kernel-server

----------------

On the exporting machine(s):
Edit /etc/exports. Specify local folders to export. Eg.

/home/mymachine/data/d4 192.168.1.1/24(rw,async) 213.334.248.237(rw,async)

opens the directories to all local machines, and the address 213.334 etc.

After change:
sudo /etc/init.d/nfs-kernel-server restart
----------------

On the mounting machines: On the fly:

sudo mount server.mydomain.com:/files /files

Possible restart required:

sudo /etc/init.d/portmap restart

sudo /etc/init.d/nfs-common restart

---------------

On the mounting machines: With fstab:

Add lines:
server.mydomain.com:/files /files nfs rsize=8192,wsize=8192,timeo=14,intr


---------------
Firewall ports:
Open 32771, 111 and 2049

sshfs

sudo apt-get install sshfs

Add users to the fuse group:
sudo adduser username fuse (i found this not to be required)

mount the remote file systems:
sshfs loginname@ipaddress:/pathtoremotedir /pathtolocalmountpoint

These are temporary. When the ssh tunnel fails, the access is lost. After a period
of inactivity, the connection is dropped.

[NO-NAME] ORTE_ERROR_LOG: Not found in file runtime/orte_init_stage1.c at line 182

OpenMPI failure (fixed)

$ mpiexec -n 4 fe2.py

[host-desktop1:09127] [NO-NAME] ORTE_ERROR_LOG: Not found in file runtime/orte_init_stage1.c at line 182
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

orte_rml_base_select failed
--> Returned value -13 instead of ORTE_SUCCESS

--------------------------------------------------------------------------
[host-desktop1:09127] [NO-NAME] ORTE_ERROR_LOG: Not found in file runtime/orte_system_init.c at line 42
[host-desktop1:09127] [NO-NAME] ORTE_ERROR_LOG: Not found in file runtime/orte_init.c at line 52
--------------------------------------------------------------------------
Open RTE was unable to initialize properly. The error occured while
attempting to orte_init(). Returned value -13 instead of ORTE_SUCCESS.

Reinstall, from a fresh build.

cd downloads
wget http://www.open-mpi.org/software/ompi/v1.3/downloads/openmpi-1.3.tar.gz
tar xzf openmpi-1.3.tar.gz

Reading the README showed, PATH and LD_LIBRARY_PATH need a specific entry. ompi_info, a program residing in /bin reports the MPI status, but it's location is of more interest.

whereis ompi_info
ompi_info: /usr/bin/ompi_info /usr/share/man/man1/ompi_info.1.gz

So /usr/bin needs to be in PATH, and /usr/lib needs to be in LD_LIBRARY_PATH.

Checking .bashrc showed LD_LIBRARY_PATH was wiped on its instantiation. The first line was changed from

LD_LIBRARY_PATH=blahbah

to

LD_LIBRARY_PATH=blahbah:$LD_LIBRARY_PATH

and things started working again.

ipython

Ipython's not behaving as expected; this is hardy. I think i installed it
early on, with

sudo apt-get install ipython

on running it, arange doesn't work. I can't install pylab etc. Start again.

$ sudo aptitude install bzr
$ bzr branch lp:ipython

Read the installation instructions and found:

$ sudo easy_install ipython[kernel,security,test]

this bloody failed, too. Try:
$ sudo easy_install ipython

seems ok.


*UPDATE*

This same command, seems to safely update ipython, too! The change from 0.8.1 to 0.9.1 was seamless. Numpy, scipy and my modules import fine. ipcluster didn't work, though: twisted
was required.

$ sudo easy_install twisted

amazing. It worked. Now foolscap is missing.

$ sudo easy_install foolscap

Unbelievable. It worked, and

$ ipcluster -n 4

works, too.

Update, May 2013:

sudo apt-get install ipython-notebook python-matplotlib \ 

python-scipy python-pandas python-sympy python-nose

now works!

CLI loops, including batch conversion of .xcf to .png

for I in {1..10}; do echo $I; done

for I in 1 2 3 4 5 6 7 8 9 10; do echo $I; done

for I in $(seq 1 10); do echo $I; done

for ((I=1; I <= 10 ; I++)); do echo $I; done


Apply to conversion of all .xcf files in a directory, to .png:

for i in `ls *.xcf`; do xcf2png $i -o $i.png; done


Sharing ubuntu directories.

Mostly from http://www.redhat.com/docs/manuals/linux/RHL-7-Manual/ref-guide/s1-sysadmin-nfs.html

and (better)

http://www.ubuntugeek.com/nfs-server-and-client-configuration-in-ubuntu.html


aptitude install nfs yielded:

Couldn't find package "nfs". However, the following
packages contain "nfs" in their name:
libyanfs-java nfsbooted libroxen-tokenfs p3nfs libnfsidmap-dev
fai-nfsroot libfile-nfslock-perl nfs-server unionfs-source funionfs
nfs-kernel-server unionfs-tools nfs-client libnfsidmap2 nfs-user-server
nfsboot nfs-common unfs3 knfs

So, I reckon nfs-server, nfs-client are probably required.

sudo apt-get install nfs-server nfs-client

shows:

Package nfs-server is a virtual package provided by:
nfs-kernel-server 1:1.1.2-2ubuntu2.2
unfs3 0.9.19+dfsg-1
nfs-user-server 2.2beta47-23
You should explicitly select one to install.

So, maybe nfs-kernel-server

sudo apt-get install nfs-kernel-server

Well, /etc/exports now exists; a good sign.

/mnt/sda2 192.168.1.108

is added. /mnt/sda2 is the shared folder. 192.168.1.108 is the machine allowed to connect.

After changes, either stop and start the daemon:

/etc/rc.d/init.d/nfs stop
/etc/rc.d/init.d/nfs start
      

or restart it:

/etc/rc.d/init.d/nfs restart

These didn't exist. More searching showed:

sudo apt-get install nfs-kernel-server nfs-common portmap

(already there)

sudo dpkg-reconfigure portmap (select no)

Restart portmap:

sudo /etc/init.d/portmap restart

Restart NFS:
sudo /etc/init.d/nfs-kernel-server restart

worked.


===========================

Install the client:

sudo apt-get install portmap nfs-common

===========================

Manual mount:

cd ~
sudo mount 192.168.1.65:/mnt/lin2/projects projects


===========================
Alternative method:
http://fuse.sourceforge.net/sshfs.html

Use ssh! Install fuse, and glib2.0-devel. Download from the link and ./configure; make; sudo make install

Then,

sshfs login@ipaddress:/path mountpoint

wow!  Useful, particularly with firewall avoidance.

sudo aptitude install xine-ui libxine-extracodecs


or maybe apt-get, that.
