O Shell móvel (Mosh).
The major drawback of mosh is that it requires the server to fulfill additional prerequisites which are not needed by ssh itself. Due to its design, mosh needs the server to allow direct connections via UDP. Servers not fulfilling these prerequisites cannot be used by mosh. Examples of such systems include servers behind firewalls which restrict connections to the ssh-port via TCP. Also problematic are servers which are only indirectly reachable. The latter is usually accommodated by ssh via the 'ProxyCommand' option, but this is not supported by mosh.
Uma porta por conexão.
By default, the server tries to allocate the first free UDP port in the range 60000-61000, per connection. This dynamic port allocation is considered an extra burden and risk for firewall maintenance. A significant part of the firewall-filtering happens through connection tracking, so called stateful filtering, this is based on the SYN/ACK flags in TCP segments, UDP packets don't have such flags.
Outras coisas.
- Não há suporte para roaming IPv6.
- Scrollback não é suportado na versão atual do mosh e, quando usado em um emulador de terminal com barras de rolagem, eles desaparecem.
- Falta de encaminhamento do SSH-Agent.
- Falta de encaminhamento do X-11.
