This script, named schedwiclnt, can be installed in /etc/init.d and links can be created in the startup folders as follow:

/sbin/chkconfig --add schedwiclnt

schedwiclnt on Cygwin can be invoked as a Windows 2000 service. Cygwin has its own cygrunsrv.exe program to define, remove, start, and stop services. The following command can be used to install schedwiclnt as a service:

cygrunsrv.exe --install schedwiclnt   \
              --path /usr/local/bin/schedwiclnt.exe   \
              --args \-f   \
              --desc "Schedwi Agent"   \
              --shutdown

The previous command has been split into several lines to fit in the page. It must be typed on a single line without the \'s.

The following commands will generate a SSL key file (schedwiclnt.key) and a certificate file (schedwiclnt.crt) on the agent.

certtool --generate-privkey --outfile schedwiclnt.key
certtool --generate-self-signed --load-privkey schedwiclnt.key \
         --outfile schedwiclnt.crt

This command will ask a number of questions. The important ones must be be replied as follow:

The value for the Common name and dnsName must be entered with great care: the full hostname must be resolvable on the server by the naming system in used (DNS, /etc/hosts, NIS, ...)

The following commands will generate a SSL key file (schedwiclnt.key) and a certificate file (schedwiclnt.crt) on the agent.

openssl genrsa 1024 > schedwiclnt.key
openssl req -new -x509 -nodes -sha1 -days 365 -key schedwiclnt.key > schedwiclnt.crt

The second command will ask a number of questions. The important one is:

Common Name (eg, YOUR name) []:

and must exactly match the hostname of the agent host including its full domain (flower.foo.com for instance). This full name must be resolvable on the server by the naming system in used (DNS, /etc/hosts, NIS, ...)

The graphical interface gschewi can be used to upload the certificate:

The command line tool schedwiloadcert can also be used to upload the agent certificate file as follow:

schedwiloadcert -a <full_host_name_of_the_agent> schedwiclnt.crt

See the section called “Using the schedwiloadcert program” for more details.
