Hi guys,
i am quiete new to gentoo and have a question, which can be answers very fast by more experienced users (at least i hope):
When starting gnome i get an error message, similar like this:
| Code: |
Can not resolve internet address for host tripol.
|
When trying to ping to tripol i get:
| Code: |
tripol ~ # ping tripol
ping: unknown host tripol
|
I have one eth0 interface on my host, which is starting up with dhcpcd at boot time automatically. Ifconfig says:
| Code: | tripol ~ # ifconfig
eth0 Link encap:Ethernet HWaddr 00:0A:E4:E0:7A:2F
inet addr:192.168.0.173 Bcast:192.168.0.255 Mask:255.255.255.0

The content of /etc/conf.d/net is:
| Code: | tripol conf.d # cat net
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"
|
Any help would be gracefully appreciated.
Thanks in advance, Andreas |

As you already suggested in the title of your post, you need to make an entry for your host in /etc/hosts. I don't rmember the details of the entry format, but something like
should do the trick. Of course, you need to replace 192.168.0.3 with your hosts IP. Also have a look at the manpage (man hosts) and the comments in /etc/hosts to see whether I forgot something.
Hope that helps.
Regards,

thanks for your reply.
I tried your proposal, but it does not work for my configuration.
The ip-address of my machine is not fixed to 192.168.0.3.
This address is dynamically assigned by the dhcp-server.
I need some mechanism to get the /etc/hosts aligned by dhcp to
the current configuration.
Unfortunately I have no idea how this can be done.
Maybe it is just an option of dhcpcd, but i dont know what and how to assign.
Regards,
Andreas |

try something like this in you /etc/conf.d/net file
| Code: |
config_eth0=( "dhcp" )
postup() {
#!/bin/bash
if [ -e /etc/hosts ]
then
mv /etc/hosts /etc/hosts.sv
fi
source /etc/conf.d/hostname
source /etc/conf.d/domainname
IP=`grep IPADDR= /var/lib/dhcpc/dhcpcd-eth0.info |cut -f2 -d\=`
echo -e 127.0.0.1 '\t' localhost '\n'$IP '\t ' $HOSTNAME.$DNSDOMAIN '\t' $HOSTNAME >> /etc/hosts
# echo -e Setting Up Host file with our info . $IP '\t ' $HOSTNAME.$DNSDOMAIN '\t' $HOSTNAME
cat << EOF >> /etc/hosts
# IPV6 versions of localhost and co
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
EOF
return 0
}

|

Hi guys,
in the meantime i solved the problem and want to share solution:
Problem was, that the dhcp server is an xp professional box.
This box uses for all distributed hosts the domain mshome.net.
But my linux box is in domain eternach.de !!!
This mismatch can be solved by updating the domain information by dhcpcd:
| Code: |
config_eth0=( "dhcp" )
# nodns must be omitted to let dhcpcd update the domain information of localhost
#dhcp_eth0="nodns nontp nonis"
|

Andreas |
