iftop, vmstat, iostat, dstat, iotop, lsof, fuser

Some utilities I find helpful:

iftop -- shows current open connections and their transfer rates
vmstat -- shows virtual memory status (found in procps package)
iostat -- shows current IO transfer rate by devices (found in sysstat package)
dstat -- combines vmstat, iostat and iostat-like info for network IO
iotop -- like top, but the focus is on IO transfer rate
lsof -- get info from currently open files
fuser -- does a subset of lsof: identify processes and users using certain files
