## DHCP
|
|
|
|
The `dhcp` command configures the network automatically:
|
|
|
|
> dhcp --verbose
|
|
DEBUG: DHCP Discover transmitted
|
|
DEBUG: DHCP Offer received
|
|
ip: 10.0.2.15/24
|
|
gw: 10.0.2.2
|
|
dns: 10.0.2.3
|
|
|
|
## HOST
|
|
|
|
The `host` command performs DNS lookups:
|
|
|
|
> host example.com
|
|
93.184.216.34
|
|
|
|
|
|
## TCP
|
|
|
|
The `tcp` command connects to TCP sockets:
|
|
|
|
> tcp time.nist.gov:13 --verbose
|
|
DEBUG: Connected to 129.6.15.30:13
|
|
|
|
58884 20-02-05 19:19:42 00 0 0 49.2 UTC(NIST) *
|
|
|
|
This could also be done with the `read` command:
|
|
|
|
> read /net/tcp/time.nist.gov:13
|
|
|
|
58884 20-02-05 19:19:55 00 0 0 49.2 UTC(NIST) *
|
|
|
|
|
|
## HTTP
|
|
|
|
Requesting a resource on a host:
|
|
|
|
> http moros.cc /test.html
|
|
|
|
Is equivalent to:
|
|
|
|
> read /net/http/moros.cc/test.html
|
|
|
|
And:
|
|
|
|
> read /net/http/moros.cc:80/test.html
|
|
|
|
## SOCKET
|
|
|
|
The `socket` command is used to read and write to network connexions
|
|
like the `netcat` command on Unix.
|
|
|
|
For example the request made with `tcp` above is equivalent to this:
|
|
|
|
> socket time.nist.gov:13 --read-only
|
|
|
|
59710 22-05-11 21:44:52 50 0 0 359.3 UTC(NIST) *
|
|
|
|
And the request made with `http` is equivalent to that:
|
|
|
|
> socket moros.cc:80
|
|
GET /test.html HTTP/1.0
|
|
Host: moros.cc
|
|
|
|
HTTP/1.1 200 OK
