[Bioperl-l] CVS difficulties & SSH changes (need feedback)
Mon, 12 Feb 2001 16:16:04 -0500
While doing some general system and security upgrades on our servers (the
main one and the anonymous CVS server). I ended up upgrading our SSH daemon
to SSH 2.4.0 and in the process I have altered the configuration so that
connections via the SSH1 protocol are now no longer allowed.
The decision to turn off SSH1 support was made arbitrarily by me :) for
system security reasons. The SSH1 protocol is being retired and has been
described as having very serious non-fixable security holes. You can read
what the ssh.com people have to say about the many vulnerabilities at:
What this means is that we should all be using SSH2 to connect. I have
verified that on unix the OpenSSH (www.openssh.com) client code has no
trouble at all in connecting to our server (both for login and cvs
commands) for both Linux and OpenBSD. On Windows I've verified that at
least the freeware Putty SSH2 client works just fine (as long as you tell
it to use ssh2).
There is one problem that is still unresolved -- it seems that disabling
SSH1 support has broken CVS access for at least 2 of our users who are
using Windows based CVS client software. This is obviously not cool and I'm
still trying to figure out what is going on.
This is where I need some help:
o If you have any problems with CVS-via-SSH on unix please let me know
directly or email the server admin's at email@example.com
o If you are a Windows CVS client user and are not having problems please
let me or firstname.lastname@example.org know so that we can help others out.
o If you are a Windows CVS client user who cannot currently use CVS drop me
a note so that I can ensure you get notified of any eventual fixes.
I'm very sorry about the inconvenience this may be causing our developers,
especially as several projects are nearing release dates.
