SSH funciona no Windows Virtual Machine, mas não em máquinas nativas do Ubuntu

Question

Eu tenho que conectar a um servidor Linux através de uma VPN para a escola. Eu sou capaz de se conectar via Putty através do meu Windows Virtual Machine, e eu também pode se conectar à VPN (Cisco AnyConnect), mas não consigo conectar na minha máquina Ubuntu original. A VPN é bem sucedida via meu terminal, só que não é ssh. Eu tento pingar o servidor, e ele apenas fica lá. Quando eu tento ssh no servidor, recebo "Connection Timed Out".

O que está me impedindo de me conectar se posso fazer isso na minha VM? Alguma sugestão?

Nota : deixei nomes reais e IPs fora.

Aqui está minha saída ao se conectar à VPN:

christopher@HAL:~$ sudo openconnect -s /etc/vpnc/vpnc-script https://secureconnect.some_university.edu
[sudo] password for christopher:

Aqui está minha tentativa de ssh no servidor uma vez conectado à VPN:

christopher@HAL:~$ ssh -v xxxxxxx.some_university.edu

A resposta estava bem na minha frente o tempo todo! Estas linhas aqui:

/bin/sh: 1: /etc/vpnc/vpnc-script: not found <-- realized it here
Script '/etc/vpnc/vpnc-script' returned error 127 
/bin/sh: 1: /etc/vpnc/vpnc-script: not found
Script '/etc/vpnc/vpnc-script' returned error 127

Eu executei "locate vpnc-script" e descobri que, por algum motivo, ele estava em / usr / share / vpnc / quando eu o instalei. Então, eu fiz um mkdir / etc / vpnc e movi tudo dentro de / usr / share / vpnc para lá, mudei as permissões apropriadas, e voila! Funciona! Eu ssh'd no servidor e ligado imediatamente! Isso tornará as coisas muito mais fáceis porque eu estava cansado de usar minha máquina virtual.
