1 Server with 2 IPs (2 seperate LAN) possible?
Hi All,
I have just setup a webserver running on a linux box. This server has 2 ethernet cards and only 1 is in used now. eg. 192.168.10.1 is my server IP. All users from 192.168.10.X can access my webserver. However, users from another LAN 10.10.10.X are not able to access my webserver. They can ping and receive response from my server yet web browing is not possible. I assume port 80 has been blocked somewhere in between the network across these 2 LANs.
What I am trying to do is to connect another cable to 2nd ethernet port with IP 10.10.10.1. This means my machine is now connected to 2 seperate LANs (192.168.10.X and 10.10.10.X) - these are static IPs.
I am hoping that by this way users from 10.10.10.X network can access my webserver...they will go through the 10.10.10.X router/switches and reach my server 2nd ethernet card 10.10.10.1.
Is this possible? Do I need to setup any routing on my server? Another question is, what if my server has a domain name eg. linuxsrv01.domain.com and this domain is linked to 192.168.10.1 (my first IP). Users from 192.168.10.X network can access my webserver by typing linuxsrv01.domain.com on thier web browser (this is ok and confirmed). Question is, with the above setup, will users from 10.10.10.X network be able to access my webserver by typing linuxsrv01.domain.com?
WIll they automatically get resolved to 10.10.10.1?
COnfused...

IDENT(8) InterNetNews Documentation IDENT(8)
NAME
ident - nnrpd ident resolver
SYNOPSIS
ident [-p port] [-t]
DESCRIPTION
This program attempts to resolve usernames for nnrpd by using the ident protocol to query the remote host. It contacts the remote host
using either IPv4 or IPv6 depending on which protocol was used for the incoming NNTP connection.
OPTIONS
-p port
If this option is given, attempt to contact identd on the specified remote port (which can be a numeric or symbolic specification).
Non-numeric values will be looked up using getservbyname(3). The default value is the result of "getservbyname("ident")" if available,
or port 113 otherwise.
-t If this option is given, the identity returned will never have a domain part. That is, if the remote server returns a result
containing an "@" character, ident truncates the response at the "@". This is useful to allow the default-domain parameter in
reaers.conf to override the domain supplied by the remote host (particularly if the supplied domain part is an unqualified local
machine name rather than a full domain name).
EXAMPLE
The following readers.conf(5) fragment tells nnrpd to trust ident information for hosts on a local network, but to replace the domain
returned from the ident query:
auth LAN {
hosts: "192.168/16"
res: "ident -t"
default-domain: "internal.example.com"
}
access LAN {
users: "*@internal.example.com"
newsgroups: example.*
}
Access is granted to the example.* groups for all users on the local network whose machines respond to ident queries.
