While investigating, I set compression to 'no', retried the connection, and then the session was working.
I tried the following: - using no compression is OK - using zlib compression at any level (0..9) is OK - using lzo compression at any level (0..9) makes vtund segfault. Which encouraged me to go and check the lzo package, and got me down to: http://bugs.debian.org/394695 which refers to upstream: http://sourceforge.net/mailarchive/message.php?msg_id=1127513474.14690.2.camel%40rock.sasdatalink.com Those two refer to liblzo1 (one), not liblzo2 which vtund is linked with. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
