Ever since using this 1.7.33-0.x series (currently running 1.7.33-0.5) I've
been having intermittent trouble with one of my scripts, and just finally got
around to digging further today. This is an expect script (subroutine of a
larger system) designed to auto-login to an ssh session and then set the passwd
-R to allow further ssh sessions to have "full network powers". (I then run a
cron script which drops these rights off again every half-hour, so the "full
network powers" logins are time limited.)
The symptoms of the failure are that it sometimes fails to send the ssh
password (and thus doesn't proceed to the passwd -R command at all). If I run
the script a second time, it almost always works on the second try. After some
time has passed I run it again and get a failure, then immediately run again
and succeed. I would appreciate any thoughts as to why such a script would
fail, and then succeed on successive runs. This routine basically never failed
on the previous recent versions of cygwin (in active daily use since
approximately July 1st).

The script is called like this:
$ super.exp localhost mypasswd
and the file super.exp looks like this:
#!/usr/bin/expect
set mach [lindex $argv 0]
set pass [lindex $argv 1]
spawn ssh -o PubkeyAuthentication=no $mach
expect -exact "password: "
send $pass\n
expect {
"$ " {
send "passwd -R\n"
expect -exact "password: "
send $pass\n
expect -exact "password: "
send $pass\n
expect -exact "$ "
send "exit\n"
interact
}
"Permission denied, please try again." {
send_error "The password you provided was invalid.\n"
exit 1
}
}
