General :: How To Change Host Name By Creating File
Mar 17, 2010In order to change host name I usually create a file with this:
nano /etc/hostname (after going SU)
And in that I type the new hostname.
Also I did this too...
nano /etc/hosts
127.0.0.1 localhost <hostname>
nothing happens. OS is PCLinux
General :: Modify The /etc/host File - Change Directory Fails?
Feb 1, 2010I am in the process of setting up an Asterisk server with Broadvoice services. I am having issues with making outbound calls and Broadvoice suggests I modify the /etc/hosts file in order to add their proxy server IP address and name. I login to my server as root and get the following command line header
[root@root tmp]#
I entered cd thinking this is what I need to change directory but fails. What is the command I need to enter in order to get to the /etc/host file so I can change it? How do I confirm an /etc/host file even exists?

View 2 Replies View RelatedGeneral :: Transfer Large Number Of Files Host To Host
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.

Jun 28, 2010I had my procedure down for setting up the keys on my various machines on my LAN when I was running Fedora9 - I just followed my own notes to set up 'ssh' on one of my machines that I am upgrading to Fedora13 and am finding discrepancies. I used to be able to set files up such that if I am on one machine, I could just ssh to another and I wouldn't be prompted for passwords or passphrases etc. Whatever I did before doesn't work any more (I keep being prompted for passwords/passphrases) - does anyone have a hint to point me in the right direction on how to set up the keys etc. - or what changed from F9 to F13? Also is the handling of ssh keys the same from F9 to F13? Reading the documentation it seems that on my old machines the man page says this:
Code:
<snip> that passphrase will be used to encrypt the private part of this file using 3DES.

View 3 Replies View RelatedUbuntu 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.

View 1 Replies View RelatedServer :: 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.

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
ssh: connect to host 10.46.41.38 port 22: Connection refused
lost connection

Networking :: 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.

Nslookup mydomain.com returns the correct IP. Pinging works.
But typing in the domain name or IP through the web browser just results in a "Network Timeout...Taking too long to respond."

General :: Passwordless SSH To The Same Host?
Jun 12, 2011I am trying to run OpenNebula on a set of 2 machines. One of the machines(called host1) must be able to access the others(including itself) with passwordless ssh.Both machines have the same user and use mounted folder from host1 for home directory(exported with NFS). So single key generation should be enough for this configuration - all the machines have access to the same .ssh folder.What I am getting at the end is passwordless ssh from host1 to host2 which is great, but no success from host1 to host1. Host2 to host2 is also OK, host2 to host1 wants password like host1 to host1.Both machines have the same sshd_config and ssh_config files.File permissions required by ssh should be correct since it works for host1 to host2.The only difference(I see) between the machines is that host1 runs nfs service, so host2 has access to the exported folders.
The ssh-keygen is executed on host1authorized_keys has the same public key two times(to authorize access for host1 on host1 and host2).The distro is Scientific Linux 6.0 aand I also use rsa.Something else - no pass ssh with another user from host1 to host1 works, so I suppose the problem comes from this mounted folder.
General :: Why Can't Traceroute A Host Outside LAN

Cannot handle "host" cmdline arg `google.co.in' on position 1 (argc 1)

naman@naman-laptop:~$ traceroute 74.125.77.99
traceroute to 74.125.77.99 (74.125.77.99), 30 hops max, 40 byte packets
connect: Network is unreachable
I have to use my college proxy server to connect to the Internet. When I traceroute to a host within the LAN there is no problem. What should I do to be able to traceroute to a host outside my local network?
