error in apache http proxy

[reza1365 0]

hello dears

I installed my ERA V5 and configured it for mirror updating, so clients can get updates in this way without any problem. But then I wanted to configure proxy server so I installed apache proxy server and configured it by procedures explained here. After configuring clients to get updates from proxy server when I click update now (in smart security v10) multiple errors logged in "error.log" file in apache proxy server logs folder:

[Sun Nov 04 23:40:39.185593 2018] [proxy:error] [pid 1444:tid 12552] [client 172.21.3.89:55924] AH00898: DNS lookup failure for: update.eset.com returned by hxxp://update.eset.com/eset_upd/v10/dll/update.ver

what is the solution?

and another question: If you say I can not use proxy server for ERA v5 what is the alternative?

ERA v5 does not create a mirror for Endpoint v6.6/v7. It's a quite old product that doesn't support business v6 products and newer.

We strongly recommend using ESMC (ERA v7) without a mirror but utilizing http proxy to cache update files which will save a lot of traffic compared to mirror.

thank you Marcos, but I installed and configured apache http proxy as mentioned above and the error appeared in error.log file.

Mentioned error most probably means that it is not possible to resolve DNS name update.eset.com on machine where HTTP proxy is installed  - could you please verify it is properly configured, for example by testing "ping update.eset.com" from HTTP proxy?

Also I am not sure whether caching will actually work for non-bussiness products. It was added to v6/v7 business products, but you are using home version - is this intentional? Even if DNS resolving is no longer a problem and updating through proxy will be working, it is very probable that without caching.

Please make sure that you have Endpoint installed on all machines. Let us know if Endpoint v6 or v7 fails to update through the proxy.

I can ping update.eset.com from ERA v5 server but you (Martink) said check it from http proxy! what do you mean? http proxy and ERA v5 both installed on the same machine. another thing is that when I clear log file and start apachehttpproxy service lines below appeard:

Now "almost" every thing is OK! I connected the server to the internet and DNS error (mentioned above) disappeared! So I could update a client (smart security v10) by proxy configuration; but on another client with the same credential nor another credential I couldn't update! It appears "invalid username or password" message and a dialogue box to enter username and password.

There is no error log in this situation! I think there are something wrong on new client not in server configuration but I don't know what!

Thank to all. Every thing is OK now! The problem was that Endpoint V5 does not support proxy but supports mirror address! and smart security v 9 and newer versions support proxy. just that!
