For me, right now, 193.219.52.204 resolves to axrxt.pfi.lt, not axrxt.stp.lt. I can't get find any entry for axrxt.stp.lt at all. It appears for you that the address resolved to axrxt.stp.lt, and an IP address for axrxt.stp.lt couldn't be found. Since you have wrapping turned on in inetd, it dropped the connection as bogus. See inetd(8) and hosts_access(5). > 1/ What is 193.219.52.204 purpose? It's the source address of a machine that tried to connect to your FTP service. Since it appears its DNS was screwed up, and you had wrapping turned on for inetd, its connection was dropped and logged. > 2/ Why does it try ftp to my server? > 3/ What do they want? Those are questions for the owner(s) of 193.219.52.204, not me. > 4/ what is meaning getaddrinfo, AF_INET getaddrinfo is a function that does protocol-independent hostname-to-address translation, and AF_INET is (basically) sockets programmer lingo for IPv4. See getaddrinfo(3) and/or any book on Unix network programming. > 5/ why did try ftp instead of telnet to my server if they want to do > sth? That depends heavily on what "sth" means.
