Hello, I'm having problems with ssh-1.2.17. It stops randomly with the errormessage "Local: Bad packet length 16844810." Is there anything I have to change or upgrade to avoid this problem? I've checked the ssh homepage for a faq but couldn't find any. Some info you might need: ssh client runs on a p2-266 with redhat 6.0 + redhat 6.0 updates + linux 2.2.10. The following ssh rpms are used: ssh-extras-1.2.27-5i ssh-server-1.2.27-5i ssh-1.2.27-5i ssh-clients-1.2.27-5i This computer uses adlink 528ct ethernet card (ne2k-pci) connected to a "Motorola CableSURFR Wave Modem" to get to the internet. I'm connecting to ace.ulyssis.student.kuleuven.ac.be, a p2-350 running linux 2.2.5-22 from redhat rpm + redhat 6.0 with latest updates. I also uses the 1.2.17-5i rpms. The problem is quite annoying, until now i had to resume typing this email already 12 times. Here's some output from tcpdump: <<<typing this email>>> 10:57:56.450491 dhcp-212-123-14-10.kabel.pandora.be.1022 > ace.ulyssis.student.kuleuven.ac.be.ssh: . ack 22112 win 32120 <nop,nop,timestamp
