MAC access 是 RouterOS 的私有協定,它可以用 MAC address 連線,即使用設備端沒有設定 IP
抓封包就可以得知,它的原理是使用 UDP 廣播的方式運作,連線端及設備端都是使用 UDP 廣播來溝通,
這也是它可以不用 IP 也能連線的原因,前提是需位於同一個 L2 層
MAC-Telnet 這個是比較舊的版本了,這個版本已經無法連線 >=6.43 版的 RouterOS
版本 >=6.43 的 RouterOS 都是使用 hash 過的 password
6.43 changelog:
*) user - all passwords are now hashed and encrypted, plaintext passwords are kept for downgrade
(will be removed in later upgrades);
裡面有:
Server mactelnetd
Client mactelnet
MikroTik Neighbor Discovery protocol mndp
protocol.h 可看到使用兩個 Port,一個 5678 用來 discovery, 20561 用來溝通
#define MT_MACTELNET_PORT 20561
#define MT_MNDP_PORT 5678
mactelnetd 需配合一個帳號密碼檔 /usr/local/etc/mactelnetd.users,
格式是純文字 username:password
系統帳號也需要有一樣的帳號才能正常登入
