Thread: Firewall Config and Getting NFS client to work.

  1. #1

    Default Firewall Config and Getting NFS client to work.

    Seems that things have changed between 42.3 and 15 and I have not a clue how to set up firewall and NFS client. Firewall.config was not installed so I installed it but still nothing works. I need a clue please because all this worked fine with 42.3.

    Things have moved on, the new fire wall is called firewalld. Should be notes in the release document. and here https://en.opensuse.org/Firewalld

    I wonder if this is a connection tracking issue here? If so, the advice I gave in the following post will be of relevance...

    Hi to gogalthorp and deano, many thanks for the info. It was a bit strange that not all the components had been installed but eventually I managed to start with filewalld. Too much info for me and too many options. Where is the idiots guide just to get started with what I had before and used to work. I have a new installation so am not migrating from 42.3 in this case. Which wiki should I start with because if I go to man pages I shall be on version 16 before I finish!!! Do I need the automatic helper I ask?

    One step at a time Budgie2. Are you having trouble accessing your NFS shares from your Leap 15 machine? Can you do so when the firewalld is stopped?
    Code:
    sudo systemctl stop firewalld

    Firewalld documentation...
    https://firewalld.org/documentation/
    This covers the CLI and GUI tools. If you get stuck or are confused about something, post here and we'll help clarify further as needed.

    Only if you have a connection tracking issue

    Security changes implemented in kernel 4.7.x onwards include disabling connection tracking helpers by default. This can be enabled via /etc/sysctl.conf
    Code:
    sysctl net.netfilter.nf_conntrack_helper=1
    or if using firewalld, then it can be enabled there as well (as explained in the post I linked to previously).

    The status can be verified with
    Code:
    cat /proc/sys/net/netfilter/nf_conntrack_helper

    Hi Deano and yes one step at a time please. I stopped firewalld (in fact I am sure it hadn't started) and NFS is not running. The way I used to have NFS worked has not been changed but no joy yet!

    Hoped to have heard from you but meanwhile it seems the setting up of NFS client is quite different. I cannot browse to select the NFS local folder folder in my home directory. In fact I do not recognise any of it.

    Deleted NFS Client and started over and this time I can browse as usual. One step further on so getting there. Will need to do some more work if I am to get NFS v4 working.
