Utopia Open source utilities
| Utility | Description | Reference |
|---|---|---|
| brctl | It is a tool used to configure Ethernet bridge (Network Bridging) | https://linux.die.net/man/8/brctl |
| vconfig | It allows user to create and remove vlan-devices on a vlan enabled kernel. Vlan-devices are virtual Ethernet devices which represents the virtual lans on the physical lan. | https://linux.die.net/man/8/vconfig |
| dropbear | It is a lightweight SSH2 server designed to be small enough to be used in small memory environments, while still being functional and secure enough. | |
| dibbler | It is an implementation of DHCPv6 Server/Client | http://klub.com.pl/dhcpv6/ |
| ifconfig | Utility used to configure a network interface | https://linux.die.net/man/8/ifconfig |
| iptables | Administration tool for IPv4 packet filtering and NAT | https://linux.die.net/man/8/iptables |
| ip rule | Utility used to manipulate rules in the routing policy database control the route selection algorithm | http://man7.org/linux/man-pages/man8/ip-rule.8.html |
| ip route | Utility used to manipulate routing tables | http://linux-ip.net/html/tools-ip-route.html |
| ebtables | It is an application program used to set up and maintain the tables of rules (inside the Linux kernel) that inspect Ethernet frames. It is analogous to the iptables application, but less complicated, due to the fact that the Ethernet protocol is much simpler than the IP protocol. | https://linux.die.net/man/8/ebtables |
| portmap | It is a server that converts RPC program numbers into DARPA protocol port numbers. It must be running in order to make RPC calls. | https://linux.die.net/man/8/portmap |
