gday, our uni used to use g++ version 2.9.5 or something like that and they recently upgraded to 3.2, however they renamed the old g++ to g++2.
just wondering how i would go about doing something like that on my own computer - red hat 8

thanks

ah and one other thing

if i wanted to use ssh to go to say address.edu.au but just wanted to type ssh address how would i go about doin that? is it possible? i tried using aliases but that didnt work.. - could it be to do with the hosts file perhaps? sorry dont know much about it yet - ive been on and off linux for a while and hence keep forgetting the basics
thanks!

renaming packages:
find what files the package needs (rpm -qipl package.rpm or equivalent) and rename them. if you're lucky you could get away with just renaming the binaries, otherwise you would have to rename the libs also. throw a script together if thats the case - i wouldn't like to rename gcc + libs by hand.

ssh address thing:
you could change your dns suffix in /etc/resolv.conf to .edu.au but i wouldn't recommend it. easiest thing to do is echo "ssh address.edu.au" > ~/bin/address ; chmod +x ~/bin/address and then you could connect just by typing address - that's what i do for the boxes i access alot.

thanks for that makes it much easier to figure out whats going on
