Greetings all! (Never a dull moment with me, is there?) I've been running into some trouble with one of my machines at home. I've got 2 FreeBSD boxes hooked up to my cable modem -- one is mine, and one belongs to a friend who lives in Texas. I haven't been able to figure out what it is, but there's *something* that is making access outside of my machine extremely slow. I thought at first it was something on my friend's machine (a high-volume mailing list, or web server, etc.) that was slowing down my entire cable modem connection, but that's not the case. If I log into the console of her machine and traceroute outbound, the ping times are normal (under 60ms). However, if I log into my machine's console and traceroute outbound, the ping times are nearly 1000ms. I've shut down every possible service on my machine I can think of -- httpd, named, even the login program that logs me into my cable modem provider (Road Runner). Nothing seems to help. Netstat shows only a handful of TCP/UDP connections, most of which are my outgoing connections to other machines (telnet port, ssh port, etc.). The one thing that does seem odd is that my machine has a *lot* of entries under Active Unix domain sockets, where my friend's machine has only a few. Here's an example: (My machine) [17]data@ds9:/home/data % netstat -n | grep -c stream 20 [18]data@ds9:/home/data % netstat -n | grep -c dgram 10 (My friend's machine) [6]data@quixotic:/users/data % netstat -n | grep -c stream 0 [7]data@quixotic:/users/data % netstat -n | grep -c dgram 10 I, unfortunately, do not know a whole lot about Unix domain sockets (I know little to nothing about them, actually), so I don't know what dgrams and streams are. However, I do find it odd that while we both show the same number of "dgram"'s, I show 20 "stream"'s while she shows none. I'm suspicious that my machine is either doing something to itself, or that it could be an outside attack against it. Although I would think an outside attack would affect her machine too, and not just mine, since internally I have more network bandwidth than I have to my cable ISP. So my question to you all is: Does anyone have any suggestions on what I should check to see what the hay is going on? And please feel free to be as basic as you want... don't worry about insulting my intelligence. :) Thanks in advance! ********************************************************************** * Bryce Newall * Email: data@dreamhaven.net * * WWW: http://home.dreamhaven.net/~data * * "Insanity takes its toll.
