I've got two Linux machines plugged into my school's LAN, connected using DHCP: their IP addresses are randomly assigned. I'd like to be able to let them automagically find each other's IP.
View 1 RepliesWriting a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.

View 2 Replies View RelatedI 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.
I 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)
View 1 Replies View RelatedThe 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.
So here's the setup:
Ubuntu 10.04 host inbound port 22 open
FreeBSD 8.0 host no inbound ports open
Both hosts are running sshd currently. What would you do for the Ubuntu host to be able to ssh to the FreeBSD host? A tunnel?
Host - Fedora 12 64bit
KVM
VM - Windows Server 2008 64 bit
bridge-utils
VM can ping host and Internet but host can't ping VM.
I set VM static IP 192.168.0.205.
It turns out dynamic IP - 192.168.0.55

View 2 Replies View RelatedI 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.
Bit 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.

I'm running Arch with a barebones Xorg install and SLiM with LXDE. I'm not sure what in the world is causing the problem and haven't been able to find anything of substance in a search.
If you are running a home server/website, and want a domain name, currently you can use dyndns and others etc. to get a free one and use that so people can find you by name. So my question is, can it be done on your home server without having to use eg dyndns or others.

View 8 Replies View RelatedOn my desktop PC I use Kubuntu, and on my laptop i use mint XFCE. I dont, however, seem to be able to get them to see each other via samba. In XFCE I am using Gigolo to browse shares, and dolphin in kde. Both are the amd64 versions.Using gigolo in xfce i am able to mount shares from kubuntu by manually entering the ip and connecting, but no workgroups show up when it searches the network.When I look in pyneighbourhood the workgroup is found but the mounting fails every time.In Kde i see nothing at all in any of my network folders.
Seeing as im not using gnome, and definitely not nautilus, i dont think this applies to me.When I run "smbclient -L ROO-DESKTOP" from my laptop I can see all the shares, and other windows computers on the workgroup.
I have ubuntu installed on my laptop which works fine. It has a pcmcia wifi card. When I tried to run the kubuntu live cd it couldn't find the card. As the drivers will be the same how do I find the drivers to allow me to use kubuntu? I plan to make a live usb which I'll add the drivers to so that it'll work each time I plug in. Alternatively if I can find the drivers then I'll just enable them each time via the cd.

View 1 Replies View RelatedI have two laptops and a desktop. At any given moment I would like the desktop to be able to download a file over WAN at maximum speed while one laptop does the same over wireless and the other laptop shares files either wired through a gigabit switch or wireless over wireless G or N. Is this too much to ask from a router/switch/wireless AP combo unit with a single processor? I'm thinking it's at least a lot. What if I ran the modem into the WAN connection of a good router. Then connected a separate wireless G/N access point and gigabit switch to the LAN connections of the router? That seems to me like it would relieve some of the bottle necks I would encounter with the scenario described above AND allow me to upgrade each unit as needed.
