Re: 'linux5' resurrecton



Dave,

The firewall should not be an issue. When I tried to use the talk client I was connecting with a local user (Orion) who was logged in at the same time. But, you are right about inetd. This needs to be running in order for talk to work. I will check it out the next time I am on campus.

Yes, it looks as if there are two disks. Does anyone know what this second disk is for and why there is no entry for it in fstab? That is, if it is formatted at all.

Until we know what this second disk is for I suggest we just leave it be. However, a RAID mirror sounds like a great idea and will protect us well against hardware failures. Maybe Seth knows something about the second disk.

Happy Turkey Weekend,
Greg
