openSuSE (13.10) PXE Installation behind a firewall

English Install/Boot/Login
1

I have a nice PXE Installation server running and it works fine if I do it with the repository on my local server.

Here the pxelinux.cfg configuration:

LABEL openSuSE 13.1 64bit installer
MENU LABEL Install openSuSE 13.1 64bit
KERNEL /openSuSE/13.1.64/linux
APPEND initrd=/openSuSE/13.1.64/initrd splash=silent showopts install=nfs://pxeserver.homenet.local:/data/nfs/openSuSE/13.1.64/

However, I would like to load from the official openSuSE repository:

LABEL openSuSE 13.1 64bit installer
MENU LABEL Install openSuSE 13.1 64bit
KERNEL /openSuSE/13.1.64/linux
APPEND initrd=/openSuSE/13.1.64/initrd splash=silent showopts install=http://download.opensuse.org/factory/repo/oss

Basically this works fine as well (of course, after all it is the official openSuSE recommendation!).

But now my to-be-installed client is behind a firewall where HTTP access is usually done via a proxy and consequently the repository cannot be accessed because the installation system does not know about the proxy settings.
Does anybody have a clue how to include the proxy settings into the install system?

Please: No “dimpy” answers like “have you tried…”.

What I want to know is rather specific:

  • Can the proxy settings be included into the APPEND line ?
  • Does the initrd be enhanced to know the proxy settings (would be rather bollox, I guess).

Yes, it can

  • Does the initrd be enhanced to know the proxy settings (would be rather bollox, I guess).

No, it does not

Thank you very much for the swift and extremely precise answer. From your name here (Indian?) and especially from your answer I guess you might have some British influenced background.
I do recall an answer of similar preciseness, once having got lost somewhere in London in England and having asked a passer-by if he could tell me where was.
The answer was: “On the pavement.”.

While that Englishman had not conveyed any information which I did not have already before issuing my question your answer helped dramatically to increase my level of Information.

While such answers are definitely without any flaw regarding correctness and preciseness I would nevertheless appreciate some more decoration around the core answer.
Such decoration could especially express how the APPEND statement should look like to pass the Proxy configuration.

Would you mind adding such decoration to your perfect answer?
