I am probably not answering your question, but you really would want to set
up a bastion host that allows you to connect to that host securely and then
run those utils from there.

But to answer your questions directly it looks like you have somewhat
answered them yourself.

(a) Telnet
SSH would be more secure
Telnet communications not secure

(b) FTP
SFTP more secure

(c) Terminal Services (win 2K server)
Can use encryption.

(d) VNC (win 2K server)
Not sure about any encryption.


One place I worked we (the IT admin group) connected securely to a desktop
we had configured in Citrix and then had all the tools we needed on there,
functioned like a bastion host with a GUI.

Hi,
What are the security implications of allowing a
server to be accessed from the Web using:

(a) Telnet (on a Linux machine): (password is sent in
clear text, may be captured by a potential hacker,
anyother risks?)

(b) FTP (default FTP service on a Linux machine)

(c) Terminal Services (win 2K server)

(d) VNC (win 2K server)

Thanks for ur help,
Rgds
