My linux DNS server is connected on 10.10.x.x network which is resolving DNS queries for all 10.10.x.x network successfully I have another network at home 172.16.x.x , From 172.16.x.x i can ping to DNS server and vice verse so I created a forward and reverse zones at DNS server for 172.16.x.x. network but it is not resolving anything for 172.16.x.x network. even reloaded dns demon. but still no luck.

View 2 Replies View RelatedOur corporate wireless network uses continuously changing passwords with RSA tokens.So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked.Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked.Is there some way to prevent it from storing my password for that network?
View 1 Replies View RelatedI just recently rebuilt my RHEL 5.3 system using MONDO onto differnt hardware. The tool worked GREAT on my 32 bit system. The only problem I am having now is that since this system was built as a clone of another system on different hardware, it copied over the network definitions as well. Not good!!! So although my system is up, I can't get it on the network because it still wants to use the original NIC's that were on the other system. How can I blow away all network hardware definitions and tell the system to go out and re-discover so that I can configure them with the nessasary network information.

View 2 Replies View RelatedI work in a small research lab in my college and we work on Windows. I am planning to switch all the computers into Linux create a network.
This is a small job in the first step. I need to hook up 3 computers together such that they all communicate with a central computer (server). The users will have to log on to their accounts and run their work from the central server, be able to run applications (vlsi, CAD) stuff from the server. I (as root) should be able to take backups (using crontab I guess) and be able to create new users, administer.
Can anyone direct me to a manual or a website or a previous post that goes through these steps. I searched the forums and was lost in my effort

I am struggling to get dd to restore a disk image across a network. I imaged a hard drive using dd to an external drive but no longer have that drive. The image file itself is on another machine and the only drives I have are the single internal drives of each machine so I am trying to run the command over the network
[Code]....
The permissions on /dev/sda appear to be correct - root has rw access. I assume the problem is that the credentials for the remote account "user" are being used for "dd". Is this a syntax problem or do I have to change the permissions on sda to give write access to everyone? I don't know if changing the permissions affects only the running Linux or if anything is written to disk so I'd prefer not to make changes until I'm sure I'll be able to restore the image.

I am trying to configure the BMC on my server so I can remotely power/boot/check on the system via IPMI.The server is on a switch with an IP address to the outside on eth0.It is my understanding that the BMC gets assigned a non-routeable IP (192.168.x.x, etc), but it runs off the same NIC, eth0. Is that correct?How is the switch port configured to have two IPs on the same NIC/cable? Or do I need to have a second NIC configured for the non-routeable IP?

I am using wvdial to connect to a mobile network (I have a usb modem) and it works fine. However, I wanted to automate the connection a bit (currently I am running wvdial every time I want to connect).

View 1 Replies View RelatedI have a problem:
I am on Debian. I configured my nic with a static ip (192.168.1.56).
When I try to connect to a network, initially with ifconfig eth2 I get (correctly):
eth2 inet addr:192.168.1.56 ....
inet6 addr: fe80:221:ff:fe96:4598/64
but after a few seconds the 192.168.1.56 disappears and after some other seconds disappears the inet6 address too.
When I press in the nm-applet it requires me the password but in the meantime it try to connect.
At uni, the connection is a DHCP one. It works for the first few seconds but after it doesn't.
Any possible solution?
Here it is the relevant part of the syslog: (static ip configuration)

I have a VM running Fedora 17 on VMWare over windows 7. I want to SSH to my university server from fedora but when I try something like: ssh myuser@server.com
I don't get request for my password. If I try to SSH using PuTTY in windows, everything is OK. Then I pinged the server and got the following message:
From 192.168.0.106: icmp_seq=2 Redirect Network(New nexthop: 192.168.0.1)
It repeated over and over. I tried NAT and Bridged network connection on the VM, but I'm not sure what this means completely, so I may have messed up somewhere around here.

View 2 Replies View RelatedI'm often on my corporate network but also need to be on another network simultaneously. At the moment I have to manually switch back and forth between the two. I'm using ubuntu 10.04. I've come across an excellent document that explains how to do this: "Linux Advanced Routing & Traffic Control HOWTO" by Bart Hubert. He mentions:
make sure that your kernel is compiled with the "IP: advanced router" and "IP: policy routing" features
I've downloaded the kernel sources, but I don't find any config options with names like these in them.
sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
sudo apt-get source linux-image-$(uname -r)
Searching doesn't reveal anything
~/kernelBuild/linux-2.6.35/debian.master$ grep -iR policy . | grep -i routing
~/kernelBuild/linux-2.6.35/debian.master$
So my question is...how can I tell if the kernel I have has these config options. Failing that, how do I build a kernel that does support these things?
Additional use cases for this knowledge. (1) At work with desktop computer plugged into corporate network. Plug 3g phone into USB port. My corporate network wont allow me to access my external servers over ssh, but the 3g phone will. (2) At home on the corporate VPN, but would like to access my other local network computers.

When using Fedora in VMWare, sometimes I can connect to the internet and sometimes I cannot. I do nothing differently on different days. I restart the machine and / or shut the machine down at the end of the day. When the machine starts back up the next time, I might have an internet connection or I might not have an internet connection. The 2 computer symbol that appears in the top will also sometimes be displayed. If I have that icon and click on it, it will display connections I can use including a sys one. I have a bridged connection chosen in VMWare also. Furthermore, when I click on the System -> Administration -> Network Device Control, 'eth0' is listed and it is listed as 'active'.
Yesterday I could ping out to a specific ip address on our network ( 192.168.1.xxx ). Now, I cannot ping that same ip address. I receive an error 'Destination host unreachable'.

i want to do linux installation on client machine from server.
i configured NFS server. i actually installed all 5 CD's to one directory. these are not iso images.
i created directory /serverimage and inside this i created directory for each linux cd. i.e linuxcd1, linuxcd2 and so on ..
now my directory structure is :
cd /serverimage
ls
linuxcd1
linuxcd2
linuxcd3
linuxcd4
linuxcd5
now i exported /serverimage in /etc/exports
but when i boot my client machine with the first linux cd. and using linux askmethod
i selected NFS. i entered ip address for nfs server and directory as /serverimage
but it is not taking. saying unable to mount.
shall i create .iso images. i dont want to use .iso images since i want to configure yum repository later once client is installed. i dont know if yum repository can be installed using iso images on the server. so i just copied cdrom to directories to share it via nfs.
