Zentyal causes oracle forms web site problem...

[exekias]

Hi again,

I think it's time to do a low level debug, you can try this (in Zentyal Server):

Install tcpdump if not installed, we will use it to see packets in your network:

Code: [Select]

apt-get install tcpdump
After that you can execute this command and watch the output

Code: [Select]

# tcpdump -vvv -i eth2 src <client_ip> or dst <client_ip>
After some testing paste the result and maybe we can see what's happening

Thnks for the reply.

I tried to do it from away as i am not in the office right now but it seems that remote access to a client and to zentyal machine gives too much traffic so  it is really difficult to capture the specific traffic that this particular site gives,as the error does come up in random time...

As soon as i go in office i'll try to do it local and i'll get back...

Well, i did it. The results are on the attachment file. These are the packages that runs to the spicific client THE TIME THE PROBLEM OCCURS! And guess what...

ClamAntivirus seems to be causing...something!
How trafffic balancing and clam antivirus can combine to cause such problem...is a mystery...

If u have any news or want some more test please let me know!

Hi xtrgeo, and sorry for the delay, holidays you know...

I see 2 things I don't understand there:

1- Source IP for your tests is 10.150.1.20, which is not the same you set in multigateway rules, also I don't see any interface in that network. Am i missing something?

2- Responses seem to fail at some point, checksums are failing, see:

Correct:

Code: [Select]

    www.ygeiapronoia.gov.gr.www > 10.150.1.20.59844: Flags [.], cksum 0xefda (correct), seq 1973, ack 3838, win 12852, length 0

Incorrect:

Code: [Select]

    www.ygeiapronoia.gov.gr.www > 10.150.1.20.59844: Flags [P.], cksum 0xc697 (incorrect -> 0x2ffd), seq 1973:1990, ack 3838, win 12852, length 17

I think this error can't be caused by Zentyal, so maybe it's in your router(s) ? Have you seen this post? http://forum.zentyal.org/index.php?topic=6752.msg27159
