Weird one … We have setup a replicated server using DSA. Clients connected directly to this server are failing to gather content from bessecurity only (FAILED to Synchronize - General transport failure. - 'http://MY SERVER:PORT/cgi-bin/bfenterprise/BESGatherMirror.exe?url=http://sync.bigfix.com/cgi-bin/bfgather/bessecurity)
Content from other external sites are fine. I have flipped a client to use a regular relay (not DSA) and the bessecurity content gathers fine, so appears the issue is related directly to the DSA server. Its configured to gather external content via a proxy, but where I’m stumped is that all other external sites appear to be gathering except for bessecurity.
There are lots of reasons why testing the link via a browser may work, but a proxy may still block the download for the Root Server. Testing the download would require leveraging a utility such as cURL and matching the configuration of the Root Server fairly specifically (including potential settings like UserAgentString).
A network packet capture from the DSA Server might give you more context as to what is blocking the download and why.
