Can any one explain what those ports for ? My server is Unix, and what happen if my server is Windows and have no firewall ?
135 was used in the RPCDCOM exploit also used in the msblaster. Port 445 is used in a few things, was used with RPCDCOM, remote desktop using dameware and weak nt password, etc. If you had a windows box and it was secureed nothing would happen, if it was not secured u would be in a world of hurt.
The packets arnt very much, i would guess maybe a gig in bandwidth wasted on the.
