UUCP
Unix-to-Unix Copy (UUCP) is a UNIX tool and protocol that enables one computer to send files to
another computer. This tool is not used frequently, as users more often use FTP, SMTP, and NNTP to
transfer files.
Characteristics
•
Internet Protocol(s): TCP
•
Port Number(s): 540
WAIS
Wide Area Information Services (WAIS) is a protocol you can use to find documents on the Internet.
Thinking Machines Incorporated first developed WAIS. Some web sites use WAIS to look for searchable
indices, but it is not used frequently.
WAIS is created on the ANSI Z39.50 search protocol, and the words Z39.50 and WAIS refer to the same
technology.
Characteristics
•
Internet Protocol(s): TCP
•
Port Number(s): 210, but servers can be (and frequently are) configured on other ports, much like
HTTP servers
WinFrame
Citrix ICA is a protocol used by Citrix for its software applications, which includes the Winframe
product. Winframe gives access to Windows from different types of clients. Citrix uses TCP port 1494 for
its ICA protocol. Citrix MPS 3.0 uses Session Reliability by default. This changes the ICA protocol to use
TCP 2598. If you use Citrix MPS, you must add a policy for TCP port 2598.
A WinFrame policy could put your network security at risk because it allows traffic through the firewall
without authentication. In addition, your Winframe server can receive denial-of-service attacks. We
recommend that you use VPN options to give more security for ICA connections. You can use all of the
usual log options with WinFrame.
