File not found on server error

Hi,

We use update mirrors to deploy updates to clients. I need to know is there any solution to resolve the "file not found on server" error without reinstalling ESET or  updating from ERA proxy?

Versions we use: ERA 6.5 / Mirror ESET 6.6 / clients 6.5

We have 1862 clients and its difficult to reinstall ESET versions.Please give a solution to this matter without reinstalling eset.

Thanks!

Update files for v6.5 products and older and v6.6 products and newer are not compatible. You'll need to create a mirror with Endpoint v.6.5 or with the Mirror tool.

Instead of mirror, we strongly recommend using an HTTP Proxy to cache installation and update files which will save a lot of traffic compared to using a mirror.

Thanks for the reply.Could you please explain why HTTP proxy is better than a mirror? We have identified that newly installed client get updates around 200MB. We have 1862 clients from several branches and 1M VPN links installed.Currently we using mirroring for updates. We also using HTTP proxy for updating our servers. I need to know that only one HTTP proxy is sufficient to update all our clients? or we need to install HTTP proxy on several locations? what is the recommended number of clients that possible to update from a HTTP proxy?

Thanks!

As for the differences in the amount of downloaded data, please refer to:

https://help.eset.com/era_install/65/en-US/when_to_start_using_mirror_tool.html

 

Also I would like to correct my previous statement; Endpoint v6.6 creates a mirror for both v6.6+ and older clients (v4-v6.5).
Do you use Endpoint 6.6 to create a mirror?
What path to the mirror do you use in the Endpoint 6.5 setup?

Hi,

Yes we use v6.6 in mirrors.We do not use mirror tool, We created policy for mirrors and mirror file storage path set to C:/ partition which OS runs.

We Shifted to mirrors to decrease our network traffic.We have identified that when mirrors updating it downloads around 200 MB per day.Is this a normal thing? Also need to know that mirror tool is better than creating mirror from assigning a mirror policy?

?

Thanks!

Yes, using a mirror results in a big amount of data being downloaded with each update even if 90% of the files will never be needed by clients. Therefore if you want to save traffic, use an HTTP Proxy so that only files actually needed by clients will be downloaded and cached.

Hi,

Thanks for the reply. We use ERA server and ERA proxy in same machine.I need to know is it possible to update our all clients (Around 1869 clients) from this HTTP proxy? or we need to install separate proxy? if yes approximately how many proxy do we need to install all our clients?

I assume you mean an HTTP proxy instead of ERA proxy since it doesn't make sense to have both ERA Server and ERA Proxy in a network. If all computers are in the same network, use just one http proxy.
