My ssh connection to a Linux server dies randomly wicth 'Connection reset by peer', remote log shows: May 7 16:31:13 hsc sshd[25825]: fatal: Local: Bad packet length 300903990. setting net.inet.tcp.newreno to 0 fix my problem. If this can help : i'm running -CURRENT from yesterday, i am using stock ssh-1.2.27 (not openssh) on both sides on 33.6kbps ppp connection.
