I have installed fedora 11 in my system , during the installation process it prompted me to enter the IP ,local host and local domain name .i have entered something .but my question is that how to change that IP and the domain name which i was given in the installation process.

View 6 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?
i want to know that which application in linux will give me access to the router like in windows we use hyper terminal or i have to install a particular package

For example, my ubuntu pc has the ip address, 192.168.2.101 I want my VirtualBox to have the ip address, 192.168.2.201
I also want my Virtualbox to have port 95 open.
I have a laptop running Ubuntu 10.04 with wireless working out of the box. I've been using it for the past few weeks because my iMac G5 has really slowed down with OS X. Today I installed 10.04 on the iMac G5 as well. However, wireless isn't working out of the box as it asks me to install the Broadcom wireless driver. The problem is, without this wireless driver, I can't install the drivers.
I am wondering if I can connect the laptop, which has wireless, to the iMac with a spare ethernet cable to give the iMac internet so it can download the driver.I'd rather not have to unplug it and move it downstairs to the router just to install the drivers.
I setup DHCP on CentOS 5.5. My issue is whenever my client leases, the server gave the last available IP. eg. my dhcp ip range is 192.168.1.10 to 192.168.1.100, the server gave me 192.168.1.100, then 192.168.1.99 for the second machine. How to configure the dhcp to give the front numbers, eg 192.168.1.10 first, then 192.168.1.11 and so on. Then on option domain-name-servers 8.8.8.8; how can I include second nameserver ? 8.8.4.4 See below for my dhcpd.conf

OS : CentOS 5.3 64bit How to trace incoming and outgoing network traffic for a give user? User 'A' logs in to the system and does various network connectivity As root user need to find what are the outgoing and incoming connection that are related with user 'A'. basically need to check the connection flow. netstat will show ESTABLISHED, LISTEN etc.. need something like tcpdump
Eg:- --user option for tcpdump tcpdump -vv -nn -i eth0 host 10.200.2.1 and tcp dst port 8080 --user A Can someone tell me any tool which can do such thing? Even if it can show the process ID of the client application which is trying to establish network connectivity will do.
I have a machine (lets called it machine 1) with two networks card, eth0 and eth1. Both have static IPs. Once in a while the machine refuses to give access to the Internet via Firefox (eth0 is the route to router). Other machines on the network have no problems accessing the Internet. Eventually the machine would just magically start working again, but this time it just seems to have stayed broken. I've done some simple diagnostics and found:
a) I have another machine running Apache with a Wiki on our network - [URL]. Machine 1 is unable to connect to this Wiki. I get 'the connection has timed out'. I can ping 192.168.1.73 and it responds in the usual fashion.
b) If I try to ping www.google.com it times out with: ping: unknown host www.google.com. I can ping google using its IP address.
c) On machine 1 I have tried traceroute on both www.google.com and its IP and I just get:
1 * * *
2 * * *
And so on until hop 30. Doing this on any other machine on the network works. So while it seems I can ping internally in our network and outside, but when it attempts anything traceroute or URL related it does not work.
I have 17 system (sys1,sys2,sys3.....sys17) in my office, and i am willing to setup a dedicated system to act as a firewall for that i have selected sys1 with two NIC(eth0 for local network and eth1 for internet) and i have configured to access internet in my office for that i have opened a wellknown port 80.but my clients are not accessing the internet..
and please check my sample IP configuration !!!
interface : eth1 (ISP IP)just for example
IP :192.168.0.2
gateway:192.168.0.1
dns:202.56.230.5
dns:202.56.230.6
Interface : eth0 (my local lan )
192.168.1.1
255.255.255.0
IP address of xp clients ranges form 192.168.1.2 to 192.168.1.16 with default 255.255.255.0
my question is that which gateway address and dns i have to give to my clients for accessing internet ?...
I use an atom based processor of 1.60 ghz on intel d945gclf board. My ram is a zion 1gb @ 533mhz. Hdd is from western digital 80gb @ 7200 rpm. I have a broadband(dsl) connection from bsnl dataone (a state owned telecom service provider). I connect to internet via a huawei wa1003a ethernet/usb/wireless modem which is provided by my service provider. I need a username and a password everytime i connect to internet via dial-up.
I was using windows xp service pack ii. It was nice and easy installing my modem on xp either via usb or ethernet. Both ways it was easy as i have both the drivers with me.Only and main problem was fighting viruses. I tried many free downloadable anti-virus software to protect my maching. Initially they were fine. But after few months they stopped taking regular updates and became non-functional. I also tried symantec corporate v.10. But it has its drawbacks also. It made my machine perform like a snail.I had previously heard about linux based operating systems. But never tried one. As i am an ameteur in using computers windows xp was suiting my needs. Recently i saw an article in the newspaper about ubuntu which is a free open source operating system. And most important to me it is virus free.But here is a problem also. I cannot connect to internet. My ubuntu 9.10 karmic koala is not identifying my modem and a network between my modem and my machine cannot be established. Also i cannot create a dial-up option where i can give username and password.

I 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.
