Golang SSH host connects to Huawei NE5K router and supports more page breaks

• Using GOLANG/X/CRYPTO/SSH to implement and reference the author: Codyguo code
• Login Huawei Router Execute command display version and display ARP statistics all
• Processing of page breaks generated by the terminal screen width
• Can be used as a single device to carry out the command printout

Key code Description
