TCP: Treason Uncloaked?
Today, considering it is a holiday here in the US, I figured I’d take a day off from the tutorials and ask a question of you.
All of my servers run logwatch (which will make for a great tutorial coming up soon), and I pretty regularly see something like this in the daily output:
--------------------- Kernel Begin ------------------------1 Time(s): TCP: Treason uncloaked! Peer XXX.XX.XX.XXX:XXXX/XX shrinks window 1898670412:1898670413. Repaired.
1 Time(s): TCP: Treason uncloaked! Peer XXX.XX.XX.XXX:XXXX/XX shrinks window 1911943385:1911943386. Repaired.
1 Time(s): TCP: Treason uncloaked! Peer XXX.XX.XX.XXX:XXXX/XX shrinks window 1922304386:1922304387. Repaired.
1 Time(s): TCP: Treason uncloaked! Peer XXX.XX.XX.XXX:XXXX/XX shrinks window 1922444120:1922444121. Repaired.
1 Time(s): TCP: Treason uncloaked! Peer XXX.XX.XX.XXX:XXXX/XX shrinks window 1949802160:1949802161. Repaired.———————- Kernel End ————————-
I’m not really sure what that means, but if anyone can offer me some feedback I’d appreciate it. So far I’ve seen conflicting answers from basic Googling.
