Pokud nainstalujete do VMware virtuálního stroje RedHat Linux 9 a vyšší, možná se setkáte s problémem, jak rozchodit ethernet interface – systém při spuštění ohlásí, že není připojen síťový kabel a tudíž nemohl z DHCP získat IP adresu 🙁

Zde je popis řešení problému (abych to nemusel stále dokola hledat na WWW stránkách podpory vmWare):

Getting a DHCP Address in a Red Hat Linux 9.0 Virtual Machine
Question
I“m using Red Hat Linux 9.0 as my guest operating system. When the guest noperating system tries to get a DHCP address, the attempt fails and I get an error message that says the link is down. How can I get this guest to work properly with DHCP?

Answer
To work around this problem, become root (su -) and use a text editor to edit the following files in the guest operating system:
/etc/sysconfig/network-scripts/ifcfg-eth[n]
/etc/sysconfig/networking/devices/ifcfg-eth[n]
Also, if it exists, edit the file

/etc/sysconfig/networking/profiles/default/ifcfg-eth0

The third file is updated any time you run redhat-config-network and make changes in the Network Configuration panel.

In all cases, [n] is the number of the Ethernet adapter — for example, eth0.

In each of the files, add the following section:

check_link_down () {
return 1;
}

Then run the command ifup eth[n] (where [n] is the number of the Ethernet nadapter) or restart the guest operating system.

Note: If you later run redhat-config-network again, check the file /etc/sysconfig/networking/profiles/default/ifcfg-eth0 to be sure the section your added to it remains intact. In some circumstances, the closing curly brace — the } character — may be dropped when you use the Network Configuration panel.
