i advanced a little bit with my problem but yet still stuck far from shore.
Now i am trying to kickstart a Linux machine , The installation of the Machine goes fine and no errors could be reported while that , But after that i notice that my DHCP on the newly installed machine is not running and the ifconfig command shows no IPs attached to my interfaces , I have checked my ifcfg-eth0 , ifcfg-eth1 and there is something really weird , They are created wrongly they have a ? attached to there name ( ifcfg-eth0?) and the other one has ifcfg-eth0^M , did anybody encounter such a pb before .
Thanks
cheers

HI,
New to Unix and I inherited a network that runs DHCP in manual configuration mode. Basically, in order for a machine to get an IP it has to have an entry in dhcpd.conf with its MAC address mapped to a hostname (the hostname then maps to an IP address listed in the DNS db file). If there is... (2 Replies)

LEARN ABOUT SUSE
ifsysctl
IFSYSCTL(5) Network configuration IFSYSCTL(5)
NAME
ifsysctl[-<interface name>] - per network interface sysctl settings
SYNOPSIS
/etc/sysconfig/network/ifsysctl
/etc/sysconfig/network/ifsysctl-<interface name>
DESCRIPTION
These files are intended to contain sysctl settings, that should be applied when a network interface is created. This are usually interface
specific settings, like:
net.ipv6.conf.eth0.use_tempaddr = 1
or
net.ipv4.conf.eth0.rp_filter = 0
The settings are applied by the /etc/sysconfig/network/scripts/ifup-sysctl script executed via /etc/udev/rules.d/77-network.rules rule (see
udev(7)), after the creation and after the rename of the interface name to its persistent name (when applicable), but before the ifup
<interface name> -o hotplug may be executed to configure the interface.
The settings are not applied by default when the NetworkManager is active (NETWORKMANAGER=yes), except when the IFSYSCTL_NETWORKMANAGER=yes
variable is set in the /etc/sysconfig/network/config file.
Settings from the ifsysctl- file are applied every time an interface has been created.
Settings from the ifsysctl-interface name file are applied when the interface with the corresponding interface name has been created.
SYNTAX
The sysctl(8) utility is required to apply the settings. It supports two separator characters for sysctl keywords: a "." in default format
and a "/" in the alternate format. Therefore the syntax is basically same to the /etc/sysctl.conf file.
Interface names may contain a ".". In the default sysctl format using a "." as separator, that is any "." in the interface name of the key-
word, has to be replaced with a "/". In the alternate sysctl format with "/" as separator, normal interface names can be used.
Optionally, the ifsysctl files may contain also the $INTERFACE and the $SYSCTL_IF variables, that are automatically replaced with the cur-
rent interface name usable in the alternate format and with the sysctl-quoted interface name for the default format, before the settings
are passed to the sysctl utility.
Note also, that settings with variables in the ifsysctl (without the -<interface name> suffix), will be applied for every interface!
Further, files with variables are not compatible to the /etc/sysctl.conf file.
EXAMPLES
Settings for "eth0" and "eth0.1" interfaces
# using "." as separator:
net.ipv6.conf.eth0.use_tempaddr = 1
net.ipv6.conf.eth0/1.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/eth0/use_tempaddr = 1
net/ipv6/conf/eth0.0/use_tempaddr = 1
Settings with variables:
# using "." as separator:
net.ipv6.conf.$SYSCTL_IF.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/$INTERFACE/use_tempaddr = 1
To test your ifsysctl-eth0 or ifsysctl file, use:
/etc/sysconfig/network/scripts/ifup-sysctl eth0 -o debug
