How to transfer files between computers on a network

[kitepilot at kitepilot.com]

The reason why you HAVE to use /sbin/ip is because /sbin is not on your 
path.  Multiple reasons for that, but mostly because technically /sbin "is 
for root" (that's a VERY condensed explanation) 


As a rule of thumb (valid always if you only have one adapter) "your 
interface" is eth0 (or eth[whatever] if you HAD to change the adapter, or 
wlan0/ath0/wifi0 for wireless) 

So 

> 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
>     link/ether 00:11:2f:06:65:08 brd ff:ff:ff:ff:ff:ff
>     inet 192.168.1.64/24 brd 192.168.1.255 scope global eth0
192.168.1.64 is your IP address. 

Also, as a rule of thumb (not always true but irrelevant to you), if the 
machines are connected to the same router, only the last number changes 

so
Machine 1 is 192.168.1.64
Machine 2 is 192.168.1.66
Note that only the last number changes. 

This is valid ONLY with a netmask of 255.255.255.0 (or 192.168.1.64/24) 
which happens to be the case for just about every router you pull out of a 
shelf in Bestbuy/Circuit City/Walmart.
Don't worry about it, just assume it is "true" 

 

Finally:
>  scp /filenameA.txt/to/copy joe at 12.34.56:/copy/filenameB.txt/to

Should rather be:
scp /to/copy/filenameA.txt joe at 12.34.56:/copy/to/filenameB.txt 

Which: 

Will copy a file name "filenameA.txt", located in path "/to/copy" in THIS 
machine, to user "joe" AT machine 12.34.56, in path "/copy/to" with name 
"filenameB.txt"
If you omit the name it will be copie with same name. 

Hope that helps...
