Hi all,
I have been reading the archives for better than two weeks now trying to get
all my bugs worked out and my BIND working. I started out with 9.1.0 and
upgraded to 9.1.2 in an attempt to resolve issues.
I thought I had this licked yesterday because I finally got everything to
say
that it runs successfully. In other words, /etc/rc.d/init.d/network restart,
/etc/rc.d/init.d/named restart, rndc restart all produce successfuly output
now, BUT I still can't ping from my Windoze boxes to the internet through
my RedHat Linux 7.1 gateway.
I have copied all my config files below along with the output from network,
named and rndc starts. I do not know what to do next and I am beginning to
feel clueless.
Can anyone tell me what is wrong?
Michael
My configuration is
Linux RedHat 7.1 running BIND 9.1.2 (started with 9.1.0)
eth0 192.168.1.1 onboot=yes
eth1 dhcp onboot=yes
Win98 SE
ipaddr 192.168.1.10
configured to static ipaddr, Gateway 192.168.1.1
DNS tried both enabled to 192.168.1.1 || 24.92.226.13, etc.
also tried disabling DNS
WinME
ipaddr 192.168.1.20
configured to static ipaddr, Gateway 192.168.1.1
DNS tried both enabled to 192.168.1.1 || 24.92.226.13, etc.
also tried disabling DNS
The Cable modem goes to eth1 card on the Linux box. The eth0 card
goes to
a four port hub. The Windoze boxes go to the same hub.
I can ping from my Windows boxes to 192.168.1.1 and to the external ipaddr
as supplied by my Road Runner cable modem, currently 24.169.130.101 , BUT
I cannot ping any other address such as the nameservers on the ISP
24.92.226.13 and 24.92.225.171 . A ping to www.internic.net also fails.
/etc/rc.d/init.d/network restart produces all [OK]s and the
