Thread: genconfig hosts produces wrong /etc/hosts

Hi,

to me it seems that "genconfig hosts" produces a wrong /etc/hosts:

Code:

[root@kusu1 ~]# genconfig hosts
# 
# Dynamically generated by: genconfig  (Do not edit!)
#
127.0.0.1       localhost.localdomain   localhost
10.0.0.1        kusu1.kusu      kusu1-eth0.kusu kusu1-eth0
10.0.0.2        compute-00-00.kusu      compute-00-00-eth0.kusu compute-00-00-eth0      compute-00-00
10.0.0.3        compute-00-01.kusu      compute-00-01-eth0.kusu compute-00-01-eth0      compute-00-01
10.0.0.4        compute-00-02.kusu      compute-00-02-eth0.kusu compute-00-02-eth0      compute-00-02
10.0.0.5        compute-00-03.kusu      compute-00-03-eth0.kusu compute-00-03-eth0      compute-00-03
192.168.0.100   kusu1.mydomain.de       kusu1-eth1.kusu kusu1-eth1      kusu1

whereas ifconfig tells me, that the ip of kusu1 is 192.168.0.166:

Code:

[root@kusu1 ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:1A:92:54:44:67  
          inet addr:10.0.0.1  Bcast:10.0.0.255  Mask:255.255.255.0

          inet6 addr: fe80::21a:92ff:fe54:4466/64 Scope:Link

          Memory:c8220000-c8240000

I came across that, because I run some test, and the very first one tests ssh connectivity.
And ssh kusu1 only works if I manually edit /etc/hosts (allthough it tells me I shouldn't )
Maybe I miss something?
I run kusu 1.0 on centos 5.2.

Thanks for trying out Project Kusu.

For eth1(public network), was it set to dhcp during installation?

Yes, eth1 uses dhcp.

Can you provide the output of netedit -l?

Code:

[root@kusu1 ~]# netedit -l

Network ID Device       Network       Subnet          Network Description                      Interface Type
========== ======       =======       ======          ===================                      ==============
1          eth1         192.168.0.0   255.255.255.0   public                                   public
2          eth0         10.0.0.0      255.255.0.0     cluster                                  provision

Was eth1 changed to dhcp after installation? From netedit -l, it looks like it was set to static ip during installation?

I am not shure any more.
I had a problem with eth0, which was not active. At install I set it to static (eth0), but then for some reason it did not get activated and was set to dhcp. I set it again to static and activated it. It survived a couple of reboots, but not all. So I had to do the process again.
Anyway, maybe in the process of changing things for eth0, I changed also things for eth1.

Can you post the following files:

/etc/sysconfig/network-scripts/ifcfg-eth0 and
/etc/sysconfig/network-scripts/ifcfg-eth1

eth0:

Code:

# Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper)
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
HWADDR=00:1a:92:54:44:67
NETMASK=255.255.255.0
IPADDR=10.0.0.1
GATEWAY=192.168.0.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes

eth1:

Code:

# Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper)
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=dhcp
HWADDR=00:1a:92:54:44:66
TYPE=Ethernet

Was eth1 changed to dhcp after installation?

Rereading my personal installation log this weekend, I found that after installation, eth1 was not activated.
So yes, I changed eth1 to dhcp after installation.
And now I think I also remember that I assigned a static adress during installation. But because the card did not get activated, I changed it.

I should probably reformulate my question: How do I make genconfig aware of my change of the network settings?

Sorry for beeing sloppy in previous posts ...

You can change the database entries to ensure that eth1 is on dhcp.

# mysql -u root kusudb
# UPDATE networks set network='', subnet='', gateway='', startip='', usingdhcp=True where netid=1;

This should fix the tables and allow genconfig hosts to create the correct /etc/hosts.
