[freifunk-public] Ffsaar-fitnessforum-mettlach wieder mal kein Durchsatz

[Jan Philippi]

Hey Jochen,

hab das Gleiche auf meinem Router auch festgestellt (hab diesen nach dem
letzten Update neu "geflashed").

Nachdem ich tcp_mtu_probing auf dem Client aktiviert hatte, ging es wieder.

Scheint mit dem Bug zusammen zu hängen:
https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1254085

# echo 1 > /proc/sys/net/ipv4/tcp_mtu_probing
