  • 1.  Issues downloading with Liveupdate server

    Posted Mar 10, 2010 02:29 AM

    Our setup here has a sepm server, sav server, and mail security for exchange on our exchange servers. Our outbound connections are low bandwidth and high latency. SO in an effort to consolidate we are trying to migrate everything to pull from a single liveupdate administrator server.

    The lua server is set up and trying to work, however it has issues downloading any kind of larger file. The behavior of the sepm server of breaking any kind of download into smaller 3.something meg chucks allowed it to work flawlessly, is there any way for lua to duplicate that behavior?

    Are you unable to complete any download task.?Try by setting up the download to off business hours...

    Can you explain this "The behavior of the sepm server of breaking any kind of download into smaller 3"

    I can complete some downloads as long as the download itself contains no large files it succeeds, so a couple of the smaller product patches, other minor updates are in the system and working fine, just the large downloads like full av definitions fail. Also as far as bandwidth is concerned, there is no off hours, we use every byte of bandwidth we pay for.



    From the sepm live update logs. It starts a download of a 5.5 meg file, then graps the zipped version instead reducing the size to 5.2 meg then further segments it into 3584000 byte chunks and downloads those. I dont have any currently for copy paste but the LUA logs indicate it straight up just trys to download the original large file. I have debugging turned on so im seeing as much as possible when it comes to the log files.

    Do you have any firewall /proxy between Internet and LUA.?
    If yes try by bypassing it.

    Yes there is a firewall and yes its configured to all that server to talk all it wants to the internet.

    The files LUA fails on I can open a webbrowser and manually download, so its not being blocked by the firewall, however LUA just chokes on it for some reason.

    From the LUA logs it has all these files (truncated of course) going through them all checking them it succeded on every file that was small and if it was large it failed.

    So hence the question, can i force LUA to exibit the same behavior as SEPM and break any large file into smaller chunks which makes this whole thing work better for our connection.
