someone from 218.27.194.67 wants to..

by bently / November 10, 2006 5:15 AM PST

I am gettin popup from Kerio 2.1.5 saying that someone from....
218.27.194.67 , port 40139 - UDP
221.209.110.50 , port 42920 - UDP
204.16.208.239 , port 33460 - UDP
204.16.208.74 , port 36369 - UDP

They keep on coming and I am denying...

wants to send a UDP datagram to port 1027 owned by Kerio PFW.

I do now know who is sending these, but they are persistant, just as soon as I deny one, another pops up.

I did not check "create appropriate filter rule and don't ask me again, I just clicked DENY.

1. I understand that Kerio does not support version 2.1.5. So is this from Kerio, or someone else?

2. How do I check who is sending these?

Thanks

Ben

BTW.... this forum page is totally whacked, did you make a major change or is my computer screwed up again

did not check "create appropriate filter rule and don't ask

you need to click first 'create rule' and then 'deny'.

this will stop it.

or you can create a new rule at the end of your rule set to 'block all'.

I am on line if you want to chat about this.

Asia Pacific Network Information Centre.

don't know what the heck they wanted, but they sent over 30 attempts.

I clicked DENY "permanently".

Thanks for the help

forget about the 'block all' rule.
by dawillie / November 10, 2006 8:42 AM PST

Simple rule of thumb as follows:

All the software you have loaded will have their servers periodically send you a TCP [Transfer Control Protocol] package.

This is usually done to measure packet rate, nothing else.

This pop up will identify the sender company.

On the other hand, when you see 'someone' i.e. a company or person who does not identify, trying to send you a message and using a port not normally used to boot, your response should be 'create rule' & 'deny'.

for the record if you make a mistake and deny some software server, no harm done.

Hope this helps.

Will be on line on Saturday am. Pacific Standard Time say around 8:00am if you want to know more.

KPF is quite a simple firewall, once you understand what is occurring and the many 'someones' you are seeing are probes to see if you are vulnerable, you will be OK.

Realise mine comes from a lot of experience but I have learned about this firewall for about 6 years now and feel I know it quite well.

Will be happy to share.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
