The Default Gateway or the Default Router is the IP address (IPv4) to which all the traffic to any target destination(s) which does not have a route in the Routing Table of the server will be forwarded.
This Default Gateway is maintained in the file
/etc/defaultrouter [IPv4 only]
To add a Static Route in Sun Solaris operating system, you can use the route command. This will dynamically update the Kernel IP Routing table. However, when a server is restarted, these routes will be lost. To prevent this from happening, add a startup script S76static-routes with all the route commands for the static route that needs to persist. This will ensure that the route gets added at boot time.
If you know there is always going to be a permanent route for a destination then a static route can be a viable option.To add a persistent static route in Redhat Enterprise Linux create a file called route-<int>X in the /etc/sysconfig/network-scripts/ directory
Yes, I came across this website and have to say was quite stunned to see the number of resources from around the world from where you can traceroute to your IP address or Domains. This is a very valuable online resource as it should help or atleast aid you to troubleshoot your WAN network problems.
The website is http://www.traceroute.org/
Great Resource!!!
Netdiag helps isolate networking and connectivity problems by performing a series of tests to determine the state of your network client and whether it is functional. These tests and the key network status information they expose give admins a more direct means of identifying and isolating network problems.
netstat is one of the most commonly used tool in Windows and UNIX & Linux operating systems to troubleshoot TCP/IP connections. Netstat displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols). Used without parameters, netstat displays active TCP connections. (more…)
