Its OK. The address 192.186.128.1 is apparently internal and is actually being used as a bridge address on a machine that is using VMware. Don't know why its sending out DHCPDISCOVER messages but it is. Basically panic over.
Currently I have a DHCP network on 10.44.27.0. While trailing through the dhcp.log I noticed a dhcp request from 192.186.128.1 Does this have the trade marks of a hacker or is something a bit more weird going on?
Quick lesson.

True it could be the OS or an app but in most cases its a faulty NIC. However the point was that you cannot ping 127.0.0.1 if the machine has no NIC. Turning off lo0 is basically the same as pulling the bugger out.
AH the ethernet one is different.
Say for example you have a user that has reported lack of network connectivity. Now no one else in the department they are in are reporting any problems. So, the first thing you do is ping 127.0.0.1 which is the loopback address or the NIC to see if it works...
"Pinging 127.0.0.1 will work regardless of whether the NIC works or not. You can successfully ping 127.0.0.1 even if you don't have a NIC in the computer. "
err no actaully you can't. Try it, or infact bring down lo0 and try to ping 127.0.0.1
# ifconfig lo0 down
# ping...

Yeah had to do the grep whatever .sh_history > cli.sh
Pretty sure, in fact I know there is, a ctrl then some key. God its doing my head in !!!
Must remeber to add the manuals in next time I build a server.
YEah already set. I know there is a ctrl something to enter the command line into vi editor. This way a huge cli can be saved for future refrence. All I need to know is what the ctrl+ ???? Key press.
Looks like a 10-15 min read of
man ksh
for me then.
Root partion should only be very small like about 750MB. All other stuff should be on a seperate slice. Once the root partion fills the box will come crashing down around you.

There is a .profile in your home directory. This is where you should set up stuff like the PATH and other variables.
Personaly I wouldn't use the SUN cc compiler it can be a bit slack at times. Use gcc instead which can be downloaded from www.gnu.org
After just typing out a rather large command line and getting it wrong half way through I remembered there was a key press to put it into vi. Can any tell me what it is.
