quadratic linear form XFX with matrix

F:  1   1
    1   1

in canonical base can be expressed as X' F' X'

X'  1   0   X'   
    0   0

where X'=A-1X, F'=AFA and A is transition matrix. Canonical base vectors are [1,0] and [-1,1]. Thus this is correct that (a+b)^2 = a^2 + b^2 + 2ab

ok, but sysadmin said "For RIP packets that do NOT contain a Netmask, like yours, it presumes the use of the old and very deprecated classful designation of Subnets" so?

comment what is the meaning of rip packet information?
but how this can be not in conflict with fact that class C contains addresses in range 192.0.0.0 - 223.255.255.254? 89.xx.xx.xx doesn't fit into it, does it?

so 89.75.40.0 is another network, not my network? it just says that this network is in my scope? what exactly this means? I have checked this is the same ISP

comment trace ftp file data in wireshark
It might be more complicated in this case because it goes from my machine through TP-Link to my server and back. In FTP-Data frame I see TP-Link as source, not server which is behind TP-Link

comment trace ftp file data in wireshark
I ve found, forget that data comes from port 20. One question: this stream comes to also different port on ftp client but I cannot find where client passed this info to FTP server. Is this that number passed with Port request?
