If you prefer to suppress case comments, use the following: scp <filename> <case_number>@tacupload.paloaltonetworks.com:silent
When prompted, enter the email address of the case contact for the password
Once the upload completes wait about 5 minutes. A comment will be added to the case if the silent option was not used.
The uploaded files will not be visible in the file uploads section of the case, but TAC will have access to the files.
Note: For SCP, the WinSCP client and other clients that require command line shell access will not work because interactive SSH shell logins are disabled for security reasons. Only users that go straight to the SCP file transfer (most command line based SCP users) will work.
