Ubuntu Networking :: Transfer Files From Cluster To Host And Then Host To Another?
Mar 4, 2010I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.
Networking :: How To Find Least Busy Host Given Hardcoded Host List?
Oct 12, 2010I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

Oct 20, 2010I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
Server :: Apache2 Virtual Host Defaulting To Default Host
Oct 30, 2009Bit of an odd one, this. I've migrated a website from my old server to a new machine. Both servers run Ubuntu + Apache2. Both only serve a single site, apart from the default site.I've flipped the domain name to the new IP address.The trouble is that after moving the virtual host config over into sites-available, with the necessary link in sites-enabled, Apache attempts to serve from the default web root (/var/www) rather than the actual site content (in /var/www/technology). So for example, an attempt to browse.

View 4 Replies View RelatedNetworking :: Very Low Network Performance In Host-to-host Connections
Jan 27, 2009The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc.
- connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays)
- traffic shaping is not running
- there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago.
- changed the internal NIC with another
- connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R.
- R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R).
- the problem persist only between R and machines from the internal network.

Ubuntu :: Copying A File By Rcp To Rcp Host To Host
May 9, 2011I am a bit of a n00b when it come to linux but I am setting up a test environment were I have a appliance monitoring network traffic. Part of my test requires me to copy a file via RCP from one host to another host. I have two ubuntu boxes. I have allowed the subnet in the etchost.allow for ALL. I have installed rsh-server
When I try to copy the file it looks like it tried to use SCP instad of RCP because it connects to 22 instead of 544. Also note that traffic must be unecrypted thus me trying to use Is there anyway to make ubuntu go old school to allow me to use rcp instead?
Code:
testuser1@ubuntu:~$ rcp /home/testuser1/test.txt testuser1@10.46.41.38:/home/testuser1

View 2 Replies View RelatedProgramming :: Determine What CPU Thread Is On?
Jul 2, 2010Is there a library/system call that will return to me what CPU core a thread of execution is running on? I've looked for a bit on the net already and also in /usr/include and couldn't find one.
getcpu() and sched_getcpu() are two that I found, but when I include the appropriate header files (linux/getcpu.h, and sys/sched.h respectively), gcc says getcpu.h doesn't exist and the linker complains it cannot find the implementation in sched.h.
I'm sure I'm doing something really stupid or overthinking...
What I am doing is running an OpenMP application and specifying a list of cpu cores to run on with GOMP_CPU_AFFINITY. I want to make sure that each core is getting the same number of threads.
**UPDATE**
It seems that this code works, but only with glibc >= 2.6, and my machine has 2.5:
Code:
#define _GNU_SOURCE
#include <stdio.h>
#include <utmpx.h>
int main( void )

General :: Determine Which Programs Are Using Swap / How Much
Apr 20, 2011I'm interested in figuring out which programs on my machine are using swap, and how much each is using. I realize this can probably be done with top, but I am having trouble figuring how how.
What I've tried:
Start top
Press f (add column)
Press p (SWAP colum)
This adds a SWAP column, but the data doesn't seem to be correct. Top lists Firefox as using 582m of swap, but the header simultaneously reports that 0k of swap is being used.
Is there a better way to monitor swap usage?
