Platform

[edit]

The operating systems or virtual machines the SSH clients are designed to run on without emulation; there are several possibilities:

  • Partial indicates that while it works, the client lacks important functionality compared to versions for other OSs but may still be under development.

The list is not exhaustive, but rather reflects the most common platforms today.

ZOC Terminal TDI or command line Yes Yes Yes Yes Yes Yes No ? No Yes Yes SCP SOCKS 4
  1. ^ Accelerating OpenSSH connections with ControlMaster.
  2. ^ The ability for the SSH client to perform dynamic port forwarding by acting as a local SOCKS proxy.
  3. ^ The ability for the SSH client to establish a VPN, e.g. using TUN/TAP.
  4. ^ Can the SSH client connect itself through a proxy? This is distinct from offering a SOCKS proxy or port forwarding.

OpenSSH ? ? ? ? ? Yes ? Yes Yes[Note 2] Yes No[Note 3] No
ZOC Terminal full Yes Yes Alt+F Yes UTF-8 No Yes No No No Yes
  1. ^ The ability to transmit mouse input to text mode applications such as Midnight Commander
  2. ^ OpenSSH needs to be patched to ask for the pin of the smartcard. If you don't want to patch OpenSSH you can use ssh-agent (the link is in french)
  3. ^ Validated [1] when operated on Red Hat Enterprise Linux 5 in FIPS mode
