HELP: SCO Unix Subnet Rejectd

HELP: SCO Unix Subnet Rejectd

Post by Fred Heber » Fri, 04 Jul 2003 05:52:53



I am trying to help a friend who has a SCO Unix server.  We are trying to
connect to it through a VPN from a remote site.  The VPN is OK because I
can connect to other boxes on his network, but the SCO box is like a black
hole if you are not on the same subnet.

The subnet on the SCO box is 192.168.0.0/24 and on the remote site it is
192.168.1.0/24.

Several years ago I worked at a place that had some SCO UnixWare servers
and it seemed that we had to create a /rhost table or something, but my
memory is very fuzzy.

Can anyone help?

Thanks in advance,
Fred.

 
 
 

1. Help: machines on subnet can't ping the machines outside subnet

Hi!
  I set up a linux box (running 1.1.75, 2 NE2000 cards) as a gateway of a
subnet.  One ethernet card connects to subnetwork and the other connects to
backbone.  My problem is the machines on the subnetwork cannot ping the outside
world.  I can ping the machines on the subnetwork and the outside world from
this linux box.  The kernel is compiled with IP_FORWARD option on.  And there's
no routed/gated running.  Here are "rc.inet1" and the result of "netstat -nr".

# rc.inted1:
/sbin/ifconfig lo 127.0.0.1
/sbin/route add 127.0.0.1

GATEWAY="192.6.1.254"
IP="192.6.8.17"

SUBIP="192.6.112.1"
SUBNET="192.6.112.0"
SUBMASK="255.255.112.0"
SUBCAST="192.6.112.255"

/sbin/ifconfig eth0 ${IP} broadcast ${BROADCAST} netmask ${NETMASK}

/sbin/route add default gw ${GATEWAY} metric 1 dev eth0
/sbin/route add -net ${SUBNET} netmask ${SUBMASK} gw ${SUBIP} metric 0 dev eth1
# End of rc.inet1

# netstat -nr

Any suggestion will be appreciated.
