Large file transfer/update MSSQL datebase

.KROPKA.

Hi,
when i update my client app that use MSSSQL datebase it will update datebase on server. When it happend it manage push it up to about 75% and then it's shutdown. When i try again it looks like nothing happen and i can't update datebase (when connected througe OPENVPN). When i do it with local connection every thing run good and finish.

I try changing mtu on server, client, windows tap to 1400, 1500,comment/uncomment fragment, mssfix.

I try few weeks but i can't mange it. Any help is great.

My openvpn --version:

It's best to use the --fragment and/or --mssfix options to deal with MTU sizing issues.

.KROPKA.

But is it MTU issue?

I have set up fragment and mssfix and it didn't help.

TinCanTech

.KROPKA. wrote When it happend it manage push it up to about 75% and then it's shutdown. When i try again it looks like nothing happen and i can't update datebase (when connected througe OPENVPN).

.KROPKA. wrote But is it MTU issue?

If it is MTU then it would have failed immediately.

Remove all your config directives which reference MTU, go back to the basic default settings,
Try again and watch your logs, keep them set to verb 4.

I suspect you had a time out at reconnect due to --reneg-*

Right at the end of your log, the client timed-out ... some network error maybe ?

fragment max

Comment out or remove the above and try again.

"max" is not a value, please see --fragment max in manual 2.4:

I comment out, restart service and it didn't help.

Event make it worst becouse i can make only to about 50%, not 75%.

Second thing i can only upload from client to server up tu 3 Mb using open vpn, localy up to 300Mb. Speed test show me up to 50Mb. OpenVPN slow down connection.

TinCanTech

Try removing these:

sndbuf 0
rcvbuf 0

300000

my openvpn client got this one and i can transfer over 5 gb data without lost connection, if you can just try tcp it is better than udp on reliable .

sometime if thing not as you expect you can try wireguard it will make you happy on speed .

Some 18 minutes after connecting your client times out, you need to find out why.

Time of timeout didn't much time when i try update my datebase on MSSQL.

After adding in client side still no improvement.

So one thing to do now is try to connect TCP because it is slow but better than UDP over internet.udp does not care the contain delivered or not .

.KROPKA.

I drop from 3,5 Mb/s to 400Kb/s using TCP.

.KROPKA. wrote I drop from 3,5 Mb/s to 400Kb/s using TCP.

it is not constants 3.5 mb/s and on udp it is depend how far beween server and client one more thing is how many node the data travel . TCP is slow but it is constance and work than udp when 70 % drop connection .
