compress-ipv6 clj

(compress-ipv6 s)

Takes a string representation of an IPv6 address (full or already compressed) and returns its canonical, maximally-compressed form per RFC 5952 (lowercase hex, no leading zeros, longest zero-run collapsed to '::', leftmost run wins ties).

ifconfig-blocks clj

(ifconfig-blocks s)

Splits ifconfig -a output into a list of [name header-line body-lines].

ipv4-in-subnet? clj

(ipv4-in-subnet? ip network netmask)

Returns true if ip belongs to network/netmask.

ipv4-octets clj

(ipv4-octets ip)

join-ip-o-lines clj

(join-ip-o-lines s)

ip -o output escapes continuation lines with a trailing backslash. Join those physical lines back into single logical lines.

parse-angled-flags clj

(parse-angled-flags s)

Parses a token like flags=1008843<UP,BROADCAST,RUNNING> or options=880028<VLAN_MTU,JUMBO_MTU> returning {:value 1008843 :flags #{:UP :BROADCAST :RUNNING}} or nil.

parse-ifconfig clj

(parse-ifconfig s)

Parses ifconfig -a output into a seq of interface maps.

parse-ifconfig-block clj

(parse-ifconfig-block [name header body])

parse-ip-o-addr clj

(parse-ip-o-addr s)

Parses ip -o addr output into a map of interface-name -> {:ipv4 [...] :ipv6 [...]}.

parse-ip-o-link clj

(parse-ip-o-link s)

Parses ip -o link output into a map of interface-name -> {:mac :mtu :status :loopback?}.

parse-ip-route-default clj

(parse-ip-route-default s)

Parses ip route show default output, returns the first default route as {:address :interface}.

parse-netsh-ipv4-show-config clj

(parse-netsh-ipv4-show-config s)

parse-netsh-ipv4-show-interfaces clj

(parse-netsh-ipv4-show-interfaces s)

parse-netstat-default-route clj

(parse-netstat-default-route s)

Parses netstat -rn output for the default route. Returns hashmap with :gateway and :interface

parse-pipe-rows clj

(parse-pipe-rows s)

Splits content into seqs of fields split on |. Skips blank lines.

parse-proc-net-default-route clj

(parse-proc-net-default-route proc-net-route)

parse-proc-network-info clj

(parse-proc-network-info sys-class-net proc-net-route proc-net-fib-trie)

Parses raw /sys/class/net, /proc/net/route and /proc/net/fib_trie dumps into a seq of interface maps, mirroring parse-ifconfig.

Local IPv4 addresses are the host LOCAL /32 leaf entries from fib_trie. Each is assigned to the interface whose subnet contains it (subnets come from fib_trie; the owning interface is resolved through /proc/net/route, with 127.0.0.0/8 inferred as the loopback). The reported prefix is the containing subnet's prefix length, matching ifconfig's netmask reporting rather than the /32 host route. The IPv6 loopback address (::1/128) is added to loopback interfaces.

parse-resolv-conf clj

(parse-resolv-conf s)

Parses /etc/resolv.conf into {:nameservers [...] :search [...]}.

parse-scutil-dns clj

(parse-scutil-dns s)

Parses scutil --dns output, returning the union of nameservers and search domains across resolvers.

route-re clj
