[CentOS] [OT] odd network question
I know this is OT, but I'm not sure where else to ask. I can hope for fogiveness! :) My home router sends its logs to the rsyslog on my desktop system, and from there I can learn all kinds of interesting (or disturbing) things. I've written a really horrid shellscript (about 20 things piped together with a temp file in the middle) to give me the count of DROP events for specific incoming ports. (The "Description" field is lifted verbatim from /etc/services.) Count PortDescription - --- 140750 48825 12251 23 telnet 23/tcp 10043 445 microsoft-ds445/tcp 28691 tcpmux 1/tcp # TCP port service multiplexer 24789 discard 9/tcp sink null 21548080webcache8080/tcphttp-alt# WWW caching service 19905060sip 5060/tcp# SIP 15928089 14528545 13583389ms-wbt-server 3389/tcp# MS WBT Server 1275443 https 443/tcp # http protocol over TLS/SSL 127581 12585000commplex-main 5000/tcp# 124480 http80/tcp www www-http# WorldWideWeb HTTP 10228291 840 60001 834 7547cwmp7547/tcp# DSL Forum CWMP 821 1433ms-sql-s1433/tcp# Microsoft-SQL-Server 809 23233d-nfsd 2323/tcp# 3d-nfsd 764 personal-agent /tcp# Personal Agent This is just the first screen of it, there are many more. The data compiled here is for the last month (rsyslog is keeping the current log plus four older logs). I find it disturbing that there were 12251 attempts at telnet during that time, 2154 on 8080, and so forth. either I'm some kind of special/hot target, or else everybody gets this kind of crap and may not even know it. But the one thing I mean to ask about here is the very first item, 140,750 attempts at port 48825. What the heck is port 48825? I can't find any reference to anything that uses it online, but for some reason it is extremely popular, at least amongst the turkeys trying to break into my network! A little more grepping: grep 'DPT=48825' Firewall-Log* | grep -o "SRC=[09123456789.]*" | sort -u -t '.' -k "1.5g,1g" | less reveals that of all the source addresses trying to poke at 48825, there are 193 unique addresses. Either this indicates a heck of a lot of sites having at my firewall, or that some few sites are all spoofing their addresses. I can sort of understand people whaling away at ports that may conceal gold, from their warped point of view, but I haven't a clue why so many people would be beating on some apparently unassigned and unused port. Anyone got any clues? Thanks in advance!
