The options used with the ss commands are very similar to netstat making it an easy replacement. The ss command gets its information directly from kernel space. However this approach falls weak when there are lots of connections to display. The netstat command reads various /proc files to gather information. netstat → ss, ip route (for netstat -r), ip -s link (for netstat -i), ip maddr (for netstat -g).ifconfig → ip a ( ip addr), ip link, ip -s ( ip -stats).The functionality provided by several of these utilities has been reproduced and improved in the new iproute2 suite, primarily by using its new ip command.Įxamples for deprecated commands and their replacements: NETSTAT is considered deprecated at nowadays and others programs included in the net-tools like arp, ifconfig, iptunnel, nameif, netstat, and route.
