I've refined this quite a bit and could give a blow-by-blow but ... What it boiled down to was getting a hostname from the primary nameserver. In other words, if I ssh foo to a nameserver foo (which by coincidence is what I tried each time) without having that "foo" in the hosts table (so that the nameserver resolved the hostname rather than locally) it broke. Usually (but not always) the connection was dropped after saying 'corrupeted MAC' If I ssh to the ip of that same nameserver, it worked. If I put the 'foo' into the host table, it worked. I consider this pretty weird. However, using either the IP or including the primary nameserver in the hosts table seems to have fixed it so far. There is extensive discussion of this at http://bugzilla.mindrot.org/show_bug.cgi?id=845 (read also the bugs that it references) Summation: there are various network devices, in particular Linksys routers, that corrupt packets. See comment #2 *** Bug 112846 has been marked as a duplicate of this bug. *** I dont have a linksys router and it still happens! <a href="autoversicherung.einsurance.de/">Autoversicherung</a> If I hardwire bypass my router it still happens. So we're on the same page, auto. Even more interesting, if I ssh to just about any outside computer (which has to have remote hostname resolution and _has_ to go through my router) it works fine. Extensive discussion does not seem to have had much effect on reality. Not the first time I've seen that effect: I suspect computers/software/networks are not a faith-based process. |
