Description

The problem is that the initscripts issues a command "pump -i <DEVICE> --lookup-hostname", and if you are using something like @home they want you to specify the hostname like, eg.: "pump -h <HOSTNAME> i- <DEVICE>", where HOSTNAME is the hostname they gave you, and DEVICE is something like eth0. I have made a workaround for that; a function reads the hostname from /etc/DHCP_HOSTNAME has been added to /etc/sysconfig/network/network-functions, and the variable DHCP_HOSTNAME does allready exist in /etc/sysconfig/network/ifup. To me it looks like ifup was prepared for this, but this type of initialization got dropped in the process somewhere. I can get it tonight and make the update files available if you are interested. /Soren Thank you, could please Email me the instructions and how to put this workaround in my computer. I have since reinstalled a SERVER type instal but the problems still persists. Thank you very much. Raj Gideon Selvaraj 09/18/2001. I made a patch for /etc/sysconfig/network-scripts/network-functions
and for /sbin/ifup to make redhat work with dhcp over cable modems.
You should create a file called /etc/DHCP_HOSTNAME that contains
the hostname you need to use for dhcp to work with your ISP.
For what I know this patch works well, but I would like comments from
other parties (RedHat ??) on this.
To apply the patch to a RedHat 7.1 install, type as root:
patch -p0 <dhcp.patch
Where dhcp.patch contains the following:

Fixes /etc/DHCP_HOSTNAME for cable modems
Going through and cleaning up old bug reports. Does this problem still exist or can I close it? No response will be taken as an affirmative. Dan |
