RH 6.2 Networking problem

RH 6.2 Networking problem

Post by Mark Fare » Sun, 31 Dec 1899 09:00:00



I just updated my home-brewed server from RH 6.0 to RH 6.2 but cannot
now get networking to work

The NIC (eth0) seems to install just fine (IP 192.168.1.1) but when I
try to ping it from the LAN (from 192.168.1.3) and do an ifconfig I see
all RX packets are dropped. Similarly, I can't ping 192.168.1.3 from my
Linux box.

Incidentally, networking is configured with NETWORK=192.168.1.255,
NETMASK=255.255.255.0 and GATEWAY=0.0.0.0 (all pretty standard stuff, I
think).

I read the Release Notes for 6.2 and particularly the comment about
source route verification in /etc/sysctl.conf but this feature is now
turned off (and anyway it shouldn't apply).

Am I missing something obvious? I'm a newbie to Linux so I don't have a
profound understanding of how this works but it seems to me that a
straight installation should result in networking working pretty much
straight out of the box. At least that's how 6.0 worked.

Regards to all and thanks in advance,
Mark.


 
 
 

RH 6.2 Networking problem

Well, if computer 1 is setup with:
     IP address     192.168.1.1, subnet mask 255.255.255.0
then the Network is 192.168.1.0

As far as the Gateway goes, is this a stand alone network?  No connections
to the outside world?
Then gateway doesn't matter.  If they do connect to other networks, or the
outside world (probably using the Internet), then the Gateway is the
device you connect to for other networks, such as a router, or perhaps a
Linux machine with IP Masquerading.

For your choice of class C LAN (192.168.1.), normally BROADCAST uses
192.168.1.255, and NETWORK SHOULD be 192.168.1.0. If it wasn't simple
typo, change it and try again.
Cheers.
 
 
 

1. install RH 6.2 over RH 7.0, install problem

Hi,

after several trials I managed to start the RH 6.2 installation manager using:
boot dkb0 -file kernels/generic.gz -flags "root=/dev/hdc"   in SRM.
When I choose KDE workstation installation in the installation manager I get the following error:
"An error has occured - no valid devices were found on which to create new filesystems. Please check
your hardwarefor the cause of this problem"

I have a Miata with 2 scsi HD's and I don't really know what kind of cd-rom.
Is this error due to a bad boot command in SRM or due to the fact that RH 7.0 is already installed
on the system ?.
If yes how do I remove it using SRM ?

Thanks a lot.
