Network configuration failed for interfaces

Support
#1

Problem:
two interfaces set. One DHCP, one static
Static failed to be identified
DHCP address is OK.

Expected outcome:

Foreman and Proxy versions:
2.3.3

Foreman and Proxy plugin versions:

Distribution and version:
CentOS 7.9

Here is the kickstart network part related produced :slight_smile:

#3

You set the IP address to 10.16.203.115 but your network seems to be:

That can’t be right. But I don’t know if that makes a difference to your problem, though.

#4

Thank you for reviewing.
Sorry I changed the IP for publishing and made a type.
IPADDR=“10.16.103.115”
Fixed. But not my problem…

#5

Once the machine network fixed by hand, we can see the command should have been worked

grep -l 24:80:0d:9e:e1:63 /sys/class/net/*/{bonding_slave/perm_hwaddr,address} 2>/dev/null | awk -F ‘/’ ‘// {print $5}’ | head -1
eno4

But the static configuration is not set:

:frowning:

#6

Please take a moment to properly format your snips.

What defines if a host will be configured with DHCP or Static is your Subnet Boot Mode setting. Check that.

#7

Hello,
Subnet boot mode is well set to Static.

#8

Are there any other ifcfg files in the directory?

/etc/sysconfig/network-scripts/ifcfg-*
#9

Yes

I’ve also tried to disable NetworkManager. No difference.

#10

It seems the script does not complete because some commands before the network interfaces files are not played. Is there any log file for ks-script- files ?

#11

Postinstall script had en error. So the end of the kickstart script was not played.
Problem was the install was not reported faulty. So I did not suspect such error.
Found the error in /root/install.post.log
Thank you for your reviewing.
