RE: Installing FC4 on new HD

In most version of Redat neat will let set everything you need. -----Original Message----- From: kclug-bounces(a)kclug.org [mailto:[email protected]] On Behalf Of Jon Moss Sent: Wednesday, August 31, 2005 5:46 PM To: kclug(a)kclug.org Subject: Installing FC4 on new HD I had a hard drive die a couple of weeks ago so I eBayed a new one and it arrived yesterday. I'm installing FC4 now. However, I wasn't paying attention (yes, I didn't RTFS) and went flying by the screen for DHCP or Manual IP. I wanted Manual IP. I also forgot to grab the memory out of the old server and put it in this one. Anyway, I know I can change the DHCP to manual when I'm done. But where/when will it ask me for the name of the server? Did I fly by that screen as well? -- Thanks very much, Jon Moss jon.moss(a)cnonline.net _______________________________________________ Kclug mailing list Kclug(a)kclug.org http://kclug.org/mailman/listinfo/kclug

The arp cache doesn't stay very long. Maybe a minute at most. IIRC DNS cache maybe, that lasts longer. Is your router doing DNS as well as DHCP? I ask because this is not default. You have to set both up separately or create a hosts file on each box. -----Original Message----- From: kclug-bounces(a)kclug.org [mailto:[email protected]] On Behalf Of hanasaki Sent: Wednesday, August 31, 2005 1:16 PM To: jason(a)stdbev.com Cc: Jeremy Fowler; kclug(a)kclug.org Subject: Re: routing problem working like a champ now! is it possible that there was something in the ip stack that had to timeout?

Seems redundant to me, most firewalls do routing as well. The only reason you would need a router is if the firewall wasn't on the same subnet. 10.1.1.1/24 10.1.1.2/24 (Internet) --- [ firewall ] --- [ router ] | | |---[ host1 ]---| 10.1.1.30/24 You can see here that you can get to the internet by going thru the router, but because the router and the firewall are on the same subnet, you can just go directly to the firewall. You just add an extra hop that is not needed and just eats up network and computer resources. If the firewall was on a different subnet, then you would need a router: 10.1.0.1/24 eth0: 10.1.0.254/24 (Internet) --- [ firewall ]-------------[ router ]-----------[ host1 ] eth1: 10.1.1.254/24 10.1.1.30 Here, host1 needs the router to reach the 10.1.0.0/24 subnet.

If you ever have to do this in Winders 2000 or XP, do "ipconfig /flushdns". It can be helpful.

Umm.. host1 and host2 are on the same subnet, so why would they have two separate default gateways? The reason its going thru host2 is because 101.1.1.10 isn't on the subnet and so it forwards packets to host2, the default gateway. He doesn't want packets to go thru host2, so you change the default gateway. Standard convention places gateways on either the first or last address on the subnet range, in the case of 10.1.1.0/24 that would be either 10.1.1.1 or 10.1.1.254. So when I saw that a) the default gateway wasn't the same for host1 and host2 it caught my eye. and b) host two had a default gateway address at the beginning of the subnet address range, so I assumed it was correct. Try not to be so condescending with your replies, makes you sound like an ass.

Is this correct? host3 = 101.1.1.10 or should it be: host3 = 10.1.1.10 -----Original Message----- From: kclug-bounces(a)kclug.org [mailto:[email protected]]On Behalf Of hanasaki Sent: Wednesday, August 31, 2005 11:04 AM To: List - KCLUG Subject: routing problem host1 host2 and host3 are all connected to the same 10/100 switch. traceroute host3 <= from host1 hits host2, the router The goal is to skip the router and go directly to host3 since they are on the same subnet. thoughts? whats the issue? and fix?
