+\S{faq-broken-openssh31}{Question} Since my SSH server was upgraded to
+OpenSSH 3.1p1, I can no longer connect with PuTTY.
+
+There is a known problem when OpenSSH has been built against an
+incorrect version of OpenSSL; the quick workaround is to configure
+PuTTY to use SSH protocol 2 and the Blowfish cipher.
+
+This is not a PuTTY-specific problem; if you try to connect with
+another client you'll likely have similar problems.
+
+Configurations known to be broken (and symptoms):
+
+\b SSH 2 with AES cipher (PuTTY says "Assertion failed! Expression:
+(len & 15) == 0" in sshaes.c, or "Out of memory", or crashes)
+
+\b SSH 2 with 3DES (PuTTY says "Incorrect MAC received on packet")
+
+\b SSH 1 with Blowfish (PuTTY says "Incorrect CRC received on
+packet")
+
+\b SSH 1 with 3DES
+
+For more details and OpenSSH patches, see
+\W{http://bugzilla.mindrot.org/show_bug.cgi?id=138}{bug 138} in the
+OpenSSH BTS.
