ss writes the system status of hosts on the local network to the standard output. The option order determines the listing
sort keys, from left to right, hightest to lowest precedence. If one or more
host operands are given then only the status to
those hosts is listed, otherwise the status for all hosts on the local network is listed.
Static information for hosts in the local network is in the file ../share/lib/cs/local on $PATH; see
cs(1) for details. Dynamic status for each active host is maintained in the file
../share/lib/ss/host by a status daemon ssd running on each host. This information is updated once a minute,
plus or minus a random part of a minute. ss starts an ssds as necessary. An ssd may be killed by removing the
corresponding host status file.
