The easiest way to do this is simply to add those three hosts to your /etc/hosts file (this is simplest since you have only three boxes to deal with) Just add lines like 192.168.1.5 box1.localdomain box1 192.168.1.32 box2.localdomain box2 to /etc/hosts doug -- Douglas R Waud, Professor Emeritus -- Pharmacology University of Massachusetts Medical School Mailing address: 17 Lantern Lane, Shrewsbury, MA 01545-2006

DCHP Private IP Hostname Resolution

by Gary J. Hanley

Greetings, I suspect this is an easy fix but somehow I can't find it.... I just installed a Netgear RP114 DSL router and I'm letting it set my private IPs with DCHP. My problem is that I need to resolve the hostnames between the 3 Linux machines on my private lan and the router isn't doing that. When they are booted in Windows the DCHP table shows the IP and hostname of each PC, but when booted in Linux the router doesn't resolve the hostname to IP...so when I ping a hostname I get nothing. Any ideas? Thanks! -- Gary

Re: [Wlug] Raw IO Howto

by Tom Guilderson

Can you do a bash$raw -qa as root and post the output. I assume that you used the "raw" command to bind the block device for raw I/O such as bash$raw /dev/raw/raw1 /dev/hdc1 On another note you may also want to check the permissions on the device file(s). This would cause the open to fail!

I get "No such file or device", which I also get if I do "ls /dev/raw/raw1" I have in /dev/{raw1,raw2...} If I change the code to open /dev/raw1, the open succeeds but the reads and writes then fail. Should I be able to see this mythical device in the /proc filesystem somewhere, cause I can't seem to find it...

Re: [Wlug] Raw IO Howto

Just a quick suggestion; open() sets perror(). try calling perror after your open() call, it might give you (and us) some insite to why you can't open the device.

Raw IO Howto

by Skip Gaede

Folks, I'd like to be able to queue read/write request to my Zip drive and bypass the buffering that goes on in the kernel. From what I've read, you can do this by binding the raw device (/dev/raw) to /dev/hdc1 for example. When I do that, I get a message that /dev/raw/raw1 has ben bound to char major 22 1. When I try open("/dev/raw/raw1",O_RDWR|O_CREAT,S_IREAD|S_IWRITE); it fails. Can someone tell me how to do this please? Thanks, Skip
