Linux Network Troubleshooting

Network Troubleshooting:
------------------------

Trace Route:
------------

-bash-3.2$traceroute IPAddress

command not found

-bash-3.2$echo $PATH
/usr/bin:/bin:/usr/local/bin

-bash-3.2$/usr/sbin/traceroute IPAddress

IPConfig:
--------

/usr/sbin/ifconfig -a -- To see the ip address of solaris system


Trace to certain activities
---------------------------

tcpdump -i eth1 host xxx.xx.xxx.xx ---- Try this in source system. It will give the information when we telnet or connect to other server. xxx.xx.xxx.xx is the IP (Example VIP IP of the RAC server) where we are trying to trace. That is the destination IP.


Telnet:
-------
telnet IP 1433

Netcat or nc is a networking utility for debugging and investigating the network:
--------------------------------------------------------------------------------

nc -v -z IP 1433
