To me all people should know is:
How long has it been since ip replaced ifconfig and route? Given the number of things ifconfig and route can't do or do incorrectly, would anyone still be using them? Are there really systems so old in use that you would need those obsolete commands anymore? At least you said host, rather than nslookup. > 1) each host on a net has a unique IP address like 192.168.1.25 (no > mention of IPv6, net addresses and netmasks); > 2) a host on a net can communicate with hosts on other nets via a router > (without detailing what difference there is between host- and net-routing); > 3) a user can see the IP address of his/her box running the ip addr list > or the ifconfig command; > 4) a user can see the routing table running the ip route list or route > commands (candidates should be able to tell if there is a default > gateway or not, that's all); > 5) a user can get the IP address of another host with the host command. > 5b) And you can ping that bastard, too! :-) > > To me including the use of ping without these topics does not make > sense; what use is ping if one cannot understand any of the data it > produces on the screen? > > >> One should at least know that there are at least three ways to compress a > >> file under the sun, and not look in amazement at a tar.xz file with no idea > >> if that is an alien creature or a tropical flower. > >> > > How about the file(1) command, then? > > > > Ain't that command terribly useful and cool and ridiculously easy? :-) file is very useful, especially when things like internet explorer has silently turned your .tgz into a .tar without renaming it. And yeah there are tons of compression methods, not that people are likely to encounter them all. gzip, bzip2, zip, 7zip, rar, lha, lzh, ace, arj, sit, and dozens more. 'theunarchiver' looks like a handy tool in fact (http://wakaba.c3.cx/s/apps/unarchiver.html). -- Len Sorensen _______________________________________________ lpi-examdev mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-examdev
