Change linux remote host *primary* IP address without disconnect

linux-howto

http://unix.stackexchange.com – I was wondering about how one could change a remote host primary IP address without getting disconnected at all (without being in a "no IP addr" state). The matter is poorly discussed on Internet (according to my research). The best resource I found is a little bit tricky (see http://madduck.net/blog/2006.10.20:freeing-the-primary-ip-address/). EXAMPLE : change 10.0.0.11/24 to 10.0.0.15/24 1. ssh root@10.0.0.11 2. ip addr add 10.0.0.15/24 dev eth0 3. logout 4. ssh root@10.0.0.15 5. ip addr del 10.0.0.11/24 dev eth0 Problem: The last command removes both IP addresses and the connectio (HowTos)

Squid Issue 3 years 20 weeks ago

Hello,

I am having a problem with Squid. I have two IP Addresses on my Server. However i don't want Squid to use the Default (Main) IP Address, i wanted it to use the Secondary IP Address.

Even though i've added the following line to my config, when i check what my IP is when using Squid, it still appears as the Primary IP, not the Secondary IP Address.

I have a Linux server A with a block of 5 public IP addresses, 8.8.8.122/29. Currently, 8.8.8.122 is assigned to eth0, and 8.8.8.123 is assigned to eth0:1.

I have another Linux machine B in a remote location, behind NAT.

Sometimes I need to move an url from an app to a browser. I select the url, say in gvim, and make Firefox window active.

hi,

i want to get the hostname for the specified IP address.

Code: # host www.google.com www.google.com has address 173.194.69.104 www.google.com has address 173.194.69.105 www.google.com has address 173.194.69.106 www.google.com has address 173.194.69.147 www.google.com has address 173.194.69.99 www.google.com has address 173.194.69.103

# host 173.194.69.99 99.69.194.173.in-addr.arpa doma

I know you can setup a CNAME record for subdomains, but I would like to redirect any requests that go to our host starting with the specified path "blog" (ex. http://host.com/blog) to another ip address.

Repair DNS Hostname mac server 1 year 13 weeks ago

I am getting this problem when checking the hostname of my server

Primary address = 176.16.1.227

Current HostName = host.example.com DNS HostName
