net/ssh: corrupted mac detected

Its Me

1/5/2006 4:13:00 AM

Never did quite get past this error when using net/ssh. Any suggestions?

[I did have the ISP upgrade their ssh some time ago, but they also migrated
servers so I can't be sure].

Any ideas? Thanks!

(this is from within a Net::SSH.start, when executing an unzip on the remote
machine ...)

unzip generated_site.zip -d generated_site...
rake aborted!

[... snip ...]

Either you've encountered a Bad Apple (sorry), or something else is wrong.

This probably doesn't help, but I do recall something about a bug around
this, but I can't remember the specifics. I'd still do a bit of a security
check to make sure no-one's sitting between and injecting stuff, but it
seems about right. The thing I'm referring to was 'Corrupted MAC on
input', and Google seems to have some hits.

Sorry if that doesn't help.
