I'm trying to make a script to authenticate in hudson using wget and store the authentication cookie.

The contents of the script is this:

wget \
--no-check-certificate \
--save-cookies /home/hudson/hudson-authentication-cookie \
--output-document "-" \
'https://myhudsonserver:8443/hudson/j_acegi_security_check?j_username=my_username&j_password=my_password&remember_me=true'

Unfortunately, when I run this script, I get:

--2011-02-03 13:39:29--  https://myhudsonserver:8443/hudson/j_acegi_security_check?     j_username=my_username&j_password=my_password&remember_me=true

There's no error log in any of hudson's tomcat log files.

Does anyone has any idea about what might be happening?

Thanks.
