Virus Scanning
Though not directly related to 'how' a file is transferred, the existence of the virus scanner in the Sametime
server helps determine 'which' method is used for transfer. The Sametime server has hooks to allow for
the operation of a third-party virus scanning tool. If the server is configured to virus scan, then the method
used for transfer must be the server. P2P file transfers do not get scanned for viruses.
RTC or P2P?
The first thing that needs to be determined is whether or not the user is allowed to transfer files. This is
done by first looking at the Sametime server setting for “Community Services
–
Allow users to transfer
files”. This is a global setting that affects all users in that Sametime community. This setting is then
combined with the Sametime User Policy setting. The outcome is the final UIM policy for file transfer.
The following table shows the possible outcomes in this scenario.
Sametime User Policy Sametime User Policy
allows file transfers does NOT allow file
transfers.
Sametime server allows UIM client allows file UIM client does NOT
users to transfer files transfers. allow file transfers.
Sametime server does UIM client does NOT UIM client does NOT
NOT allow users to allow file transfers. allow file transfers.
transfer files
- The UIM client does NOT allow file transfers .
If the UIM client does not allow file transfers and both users' (sender and receiver)
sametime.properties file contains the P2P flag (see above), and both users have P2P capability,
then the file transfer will occur via P2P; any UIM Sametime 7.5 client has P2P capabilities.
- The UIM client allows file transfers .
Once you know you have permission from the server to transfer files, the next step is to check
whether or not you have a working virus scanner on the server.
- Virus scanning is enabled on the server
With virus scanning enabled on the server, the file transfer will occur via the server (RTC)
with a message on the chat window indicating this.
- Virus scanning is not enabled on the server
If virus scanning is not enabled on the server, the file transfer will occur via P2P, if the
users (sender and receiver) both have the P2P flag set and have P2P capability. A
message is displayed in the chat window indicating that the file will not be scanned for
viruses.
In the event that either user does not have P2P flag enabled or capability, the file will be
transferred via RTC, also with a message in the chat window indicating that the file will
not be scanned for viruses.
UIM 7.5 Client and pre
–
UIM 7.5 Client
File transfer between the 7.5 client and pre-7.5 clients will always go through the server. Pre-7.5 clients
are not P2P capable. As such, when chatting from a 7.5 client to a pre-7.5 client, if file transfer is not
allowed in the user Policy, then the file transfer icon will be disabled for the pre-7.5 client user. This is the
result of a “Capabilities” check.
