Too much manual work.
When using a ~/.ssh/config file
HOST VPS-4-IPaddress
user root
ProxyJump VPS-3-IPaddress
HOST VPS-3-IPaddress
user root
ProxyJump VPS-2-IPaddress
HOST VPS-2-IPaddress
user root
ProxyJump VPS-1-IPaddress
HOST VPS-1-IPaddress
user root
ProxyJump VPS-2-IPaddress
It's also possible to chain the proxies in one line
HOST VPS-4-IPaddress
user root
ProxyJump VPS-1-IPaddress,VPS-2-IPaddress,VPS-3-IPaddress
Then you can use
ssh -D9999 root@VPS-4-IPaddress
Or without a .ssh/config file, directly on the command line (-J is equal to -o ProxyJump=)
ssh -D9999 VPS-4-IPaddress -J VPS-1-IPaddress,VPS-2-IPaddress,VPS-3-IPaddress
The manual way
You need to build local forwards from one machine to the next one.
The socks proxy will only be defined on the last one.
Client:> ssh -L9999:localhost:9999 root@VPS-1-IPaddress
VPS-1:> ssh -L9999:localhost:9999 root@VPS-2-IPaddress
VPS-2:> ssh -L9999:localhost:9999 root@VPS-3-IPaddress
VPS-3:> ssh -D9999 root@VPS-4-IPaddress
But the tunnel is more or less the same like the automatic variant.
