[olug] dhcpcd vs. dhclient

[Jonathan Warren]

I can use thechunk.m.olug.org for about 2 minutes and then the name no longer resolves unless I log into users.olug.org.  Has anyone else seen this?  Is there a way to fix it?  Has anyone written a script to update dyndns?  Something that automatically pinged the server once a day and updated my ip would be nice.
