Very Computer

I'm a beginner to Linux.  Just went through Red Hat 7.0 installation.  I
managed to get the Linksys EtherFast LNE100TX NIC to be recognized by Linux.

Now I am struggling with getting the connection to the internet.  I have a
cable modem, which is connected to a WAN port on Linksys Etherfast Cable/DSL
router BEFN2PS4 with DHCP enabled.  The NIC on Linux box (eth1) was able to
get its IP address etc. assigned by the DHCP, to be 192.168.1.12.  The
router itself is 192.168.1.1.

I can ping the router at 192.168.1.1, but there is about a 15 second delay
before the lines of ping start to get displayed.  When I try to ping the
name server at 24.40.32.33, I get "destination unreachable."

What have I not done right?  Thanks in advance for your help.

Below is the configuration of the eth1:

Device eth1
 IP: 192.168.1.12
 Netmask: 255.255.255.0
 Broadcast: 192.168.1.255
 Network: 192.168.1.0
 Boot server 192.168.1.1
 Next server 0.0.0.0
 Gateway: 192.168.1.1
 Nameservers: 24.40.32.33 24.40.32.34
 Renewal time: Mon Oct  8 03:23:41 2001
 Expiration time: Mon Oct  8 21:23:41 2001

PING 24.40.32.33 (24.40.32.33) from 192.168.1.12 : 56(84) bytes of data.
From 192.168.1.12: Destination Host Unreachable
From 192.168.1.12: Destination Host Unreachable

What is the output of your /sbin/ifconfig and /sbin/route -n commands after
pump has initialised the eth1 adapter ?

ifconfig, route -n and ipchains -L will be a good start. This will tell us
the state of the interfaces and how the machine will route.

My inital suspicions are that the cable modem isn't connecting to the ISP so
things like name resolution are not working, causing the delays your seeing.

Try this:
  route add default gw 192.168.1.1

Dean et. al.,

Thanks for your help.

Upon running "route - n", I got

Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth1
0.0.0.0         0.0.0.0         0.0.0.0         U     0      0        0 eth1

I guessed that I should take out the last line of routing.  Executing the
"route del -net 0.0.0.0 gw 0.0.0.0" worked in fact and now routing to
internet is working properly.

I don't know how the 0.0.0.0 to 0.0.0.0 routing of got inserted.

Thanks again.

It is an interesting one.  Take a look in your /etc/sysconfig/network file and
make sure that the 0.0.0.0 and gateway 0.0.0.0 line isn't making an appearance
there.  Additionally, also check to see whether or not the null default route
entry isn't being put there by a DHCP client of some sort.  I am not sure
whether or not you get your IP address from a DHCP server or whether
everything is static.

Dean,

/etc/sysconfig/network file says:
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAYDEV=
GATEWAY=
NISDOMAIN=""

I am not sure if there is anything missing or extra in it.  However, I can
tell you that there is still something wrong with the setting, because upon
trying to download Netscape 6.1 from their ftp site, I was only getting 3KB
(or 24kbs) on my cable modem, which I know is properly working at much
faster speed at the time (as I tested it by another machine connected to it
via Linksys Router running Window2000).  On your question regarding DHCP, I
did set up my Linux box to receive DHCP settings from the Linksys Router,
thinking that will make it easier for me by not having to set network
settings in Linux...

If you have any thoughts on the 'slow' internet connection, please let me
know. Thanks again.

If you are set your IP address via a static means, then you should put your
gateway information in there (or if you have a static gateway you should
probably put the gateway details in there as well).

Can't make too much of a comment on that one, but other posts to the newsgroup
have also suggested that there are problems connecting to the netscape.com
site.  For some reason people seem to get a slow response time from it.  Do
you get the same response time if you go to a mirror for netscape which isn't
at netscape.com ?

Dean,

You're right.  Netscape was the problem in the slowness.  I do get 500 to
800 kbps download according to speedteset at dslreports.com.

With the routing problem, the previously discussed 0.0.0.0 to 0.0.0.0
routing line (on "route -n" command) came back again upon rebooting the pc.
It's probably the fault of the dhcp from linksys router.  Should I give up
dhcp and just set static ip on my NIC, or is there a solution to working w/
dhcp?

Thank you

Why not just add the route del command to your /etc/rc.d/rc.local file ?
