Re: SERVER KERNEL *UDP_IN Blocked* and *TCP_IN Blocked*

Post by 5kyy »

Hello,

i got on one server also UDP_IN Blocked every seconds since long time i have seen.

If i utrace it runs to a russion location.

Frist question?
Why i got no emails to all these blocks? Other blocks for example wrong ssh password i get a block message.

Second question?
Can/Shoule i hide these messages or is there a better solution?
