Hello Is there a way for the dhcp client to send the current host name of the machine when requesting a lease ? Currently I have to include a line like DHCP_HOSTNAME=appserver2 in my /etc/sysconfig/network-scripts/ifcfg-eth0, but I would like to tell the dhcp client to just 'also send the hostname' and then the client to get the current hostname itself, instead of having the name hard-coded in the ifcfg-eth0 file. I am trying to get my router to kn...

Hallo, what is the right way in centos7 to configure the dhcp-client so that the system name is send to the dhcp/dns server (windows-domain). I found DHCP_HOSTNAME="Hostname" as entry in the device-config of the network-interface. Thanks for hints Ralf

we would like setup VLAN on CENTOS 5.X and 4.x. Only VLAN will active, but primary LAN NOT active. E.g "eth0" inactive, but "eth0.2" active. I have been tried several ways, but never successful. Any ideal? ______________________________________________________________________________________________________ ?????????Yahoo!??????2.0?????????????

It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of ifup-eth other options don't seem to be able to be passed to dhclient. I tried placing supersede ntp-servers into dhclient-up-hooks, but that also seems to be ignored, and my google fu seems to be failing on...

I am sneaking Linux and Samba into my client's IT department (with the cooperation of the IT manager) and we have a few issues getting the system talking to the rest of the network. The network we are inserting the system into uses WINS and does not have DNS for local hostname resolution. The system is required to get its IP address via DHCP. The system is running a vanilla install of

Hi. We have a Windows laptop that has gotten too slow, it's borderline unusable, so I burned a CentOS 5.2 32-bit Live CD, just to try it out in the home. It boots up fine, but it does not connect to the Internet... Now we normally connect through a wireless network, there are several around here -- on the Windows box we choose the network to which to connect... but on CentOS there is

Hi, I am having the same problem. Did you figure out how to do this? Any help in how to remove stale WINS entries from Samba would be greatly appreciated. Cheers, -farshad

My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient. I'd like to figure out what software is rewriting this file and why. man 5
