HW 2 Solution for YANDEX.cloud:

I have add dedicate file for otus hosts:

~/.ssh$ cat otus Host bastion user amartynov HostName 51.250.74.25

Host someinternalhost user amartynov HostName 10.128.0.8 ProxyJump bastion

Then I have included this file into ssh config: ~/.ssh head -n3 config include ~/.ssh/otus Host * ForwardAgent yes

IT WORKS!

~/.ssh$ ssh someinternalhost Welcome to Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-124-generic x86_64)
