for the people having issues while running steamcmd:
do not run the tool as root, make a new user then login as root and as the new user, chmod the directory like this on the root login:
cd -R 777 /etc/servers/ (i run multiply servers with over 20 ftp accounts)
then you just run the tool as the new user (NOT ROOT), be sure you give the user sudo access.
if you google it you can find it, i've googl'd it myself aswell
also here is the link were i learned from on how to do this:
https://developer.valvesoftware.com/wiki/SteamCMD
if you use 64bits, be sure to read and install the "32-bit libraries on 64-bit Linux systems" on that page i just linked. this all worked fine for me.
