How can I login to Quagga securely?

[togepy]

LEDE Reboot 17.01.0 no Telenet client
Quagga login requires telenet client
How to solve this?

Where is a telnet *client*?

There is netcat (nc) in the Image. You can use netcat like telnet. By default the newline char is \n but you can send \r\n using CTRL+V + CTRL+M in the terminal. For debugging SMTP/IMAP etc.pp it works out of the box: TCP: nc host port UDP: nc -u host port (this does not seem to supported out of the box)

Thank! Successful.

opkg install netcat
nc -T localhost 2601

Unlike PuTTY, Quagga uses [Tab]
macOS nc, too.
Do not know why?

EX：conf[tab]t[tab](enter
result：
conf
configure t
configure terminal

normal：
conf[tab]
configure t[tab]
configure terminal(enter)
