Q5 MultipleChoice

A local repository is available on this system and you need to enable clients to access this repository via HTTP. The repository information is:

PUBLISHERTYPESTATUSURI

solarisoriginonlinehttp://sysA .example.com

Identify two of the steps that are required to make the local repository on this server available to the client via HTTP.

AOn the server: set the pkg/inst_root and pkg/readonly properties for the svc:/application/pkg/server:default service and enabled the service

BOn the server: set the sharefs property on the ZFS file system containing the IPS repository.

COn the client: reset the origin for the solaris publisher.

Correct Answer: A, E

Explanation:

A: Configure the Repository Server Service

To enable clients to access the local repository via HTTP, enable the application/pkg/server

Service Management Facility (SMF) service.

# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repoSolaris11

# svccfg -s application/pkg/server setprop pkg/readonly=true

E: Use pkg.depotd to serve the repository to clients.

Start the Repository Service

Restart the pkg.depotd repository service.

# svcadm refresh application/pkg/server

# svcadm enable application/pkg/server

To check whether the repository server is working, open a browser window on the localhost location.
