Re: [Bulk] Re: basic network question



 Because my brain isn't good for much else right now, I'll 
expound on what these are and why they are useful. 

> >ifconfig -a 

show the IP configuration of all interfaces. If your network 
connection isn't good, nothing else will work. There are more 
subtle issues that can happen here -- frex, an interface that 
believes it is directly connected to a particular network will 
always be the first choice of the routing table. Even if it's 
wrong. 

> >route -n 

Show the routing table. -n means show numeric IP addresses, not 
DNS names. 

> >cat /etc/resolv.conf 

Show the DNS resolution system. This could be overriden by 
/etc/hosts or NIS, but probably isn't. 

> >dig myplaysite.com 

Get DNS data for your target. If the data is bad... 

> >ping -c 10 myplaysite.com 

Basic connectivity to your target, 10 tries. 

> >traceroute myplaysite.com 

Extended connectivity to your target: how might my packets be 
getting there? 

> >wget myplaysite.com 

Attempts a TCP connection, checks for a running web server, asks 
for content. If this works, then any problems you have left are 
with your web browser.
