Hi all,
I am having trouble getting the included expect script to work on various
dec-unix machines running unix versions 4.0f and 5.0a. It simply remains
dead once started. Also included is the trace output using alpha-trace
(www.tru64.org). I'm using Sudo version 1.6.3p5 and expect version 5.32.1.
Although there seems nothing wrong with the script-code it locks up
apparently right at the moment it tries to spawn sudo. This problem is
probably more related to Expect than OSF1 or sudo, but I'm curious if anyone
can reproduce this behavior, or comment on a possible workaround.
Any help is much appreciated.
Jacco van Buuren.
