Thread: Install SLES behind a proxy

  1. #1

    Install SLES behind a proxy

    I am going to install SLES 15 SP1 on a system behind a company proxy.
    When I am going to set up the network there is no possibility to configure proxy settings. How can I set up proxy settings?

    Re: Install SLES behind a proxy

    Maybe I need to clarigy my problem:
    I am upgrading a SLES 15 server to SP1. The install works up to the call to scc.suse.com, which seems to be mandatory and does not work, because the system is behind a mandatory proxy and I have not seen a way to configure orixy settings (as opposed to opensuse).
    So how do I tell yast installer to use the proxy?

    Hi and welcome to the Forum
    Since it's an upgrade, you need to ensure your proxy should should accept the SUSE domain (or at least selected
    sites like updates.suse.com) without authentication.

    You need to populate proxy setting in YAST and to add two lines with your proxy information to /etc/profile, for example:

    export http_proxy="http://10.10.1.1:8081/"
    export https_proxy="https://10.10.1.1:8081/"

    The above needs to be in /root/.curlrc as well.

    Re: Install SLES behind a proxy

    The problem was due to name resolution, both with the proxy name name and scc.suse.com.
    Now when I call SUSEConnect, I get the following error message:
    Error: Connection refused by server https://scc.suse.com
    Connecting to scc.suse.com using wget works, so no idea what the problem is.

    Hi
    What about curl and https?

    I had used https for sure since port 443 was given.

    Hi
    So without authentication you can get to scc.suse.com;

    Code:
    curl https://scc.suse.com
    openssl s_client -connect scc.suse.com:443

    Hi
    Hmmm, wonder if that may be the problem. Is it possible to try from another system with openssl?

    It has nothing to do with openssl, as far as I know.
