[opensuse] who is eating (my) packets?
by Per Jessen 03 Jul '19

I think I need a second pair of eyes. We are migrating a somewhat complex cluster setup from openSUSE 11.0 32bit to Leap 15.1 64bit. Just for completeness, for the topic at hand I don't think it matters, except I sort of suspect a change in behaviour due to the big jump in kernel versions. Maybe some default setting I need to tweak. I won't try to describe the complete setup unless I have to - it's not secret, just slightly complex. On a cluster node (tattoo16) I try to initiate an outbound connection over 10.0.1.144/30 on an ipip device. I use telnet - when the first response comes back, it seems to "disappear". The response comes from the external host (public IP) to my ipip network 10.0.11.146. (on outgoing, it has been appropriately snat'ed). So far so good. I see the response using tcpdump - but it never gets back to telnet. I started adding some iptables rules to log it: -t filter INPUT - nothing. -t filter FORWARD - nothing. I did the same with the nat and mangle tables, never caught anything. Then I tried the "raw" table and voila! I see my response (as I see it with tcpdump). In summary - I see the response with tcpdump and in the "raw" table, where else can I look for this response packet? I expected it to turn up in INPUT, the rest I tried in pure desperation. I know someone is going to say "firewall" at some point - the firewall has plain ACCEPT rules for everything on the ipip devices. -- Per Jessen, Zürich (19.8°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Mouse middle button
by sysek 01 Jul '19

Hello to everyone again. Dunno if I can write here with problems, but I didn't find any solutions anywhere. I have openSuSE 15.1 with xfce4 but I have no idea why the middle button doesn't work in Linux. I tested mouse with work laptop (Windows 10) and works. On my personal PC doesn't. I know that maybe silly but for me is very annoying. Maybe some met with that problem and can help? -- Cheers, MM -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
