help needed for ipfw rules
Hi, I have a problem blocking foreign intruders for specific ports in ipfw. One of my friends have 4.X-Stable running in production for proxy, e-mail, virus etc. Server also have natd and ipfw installed on it. We have following rule set. - 00050 2132 1212881 divert 8668 ip from any to any via dc1 00100 1078 4537400 allow ip from any to any via lo0 002000 0 deny ip from any to 127.0.0.0/8 003000 0 deny ip from 127.0.0.0/8 to any 004000 0 allow tcp from 192.168.0.0/24 to me 23 005000 0 deny tcp from 192.168.0.69 to me 1863 005500 0 deny tcp from 192.168.0.63 to me 1863 006000 0 deny tcp from 192.168.0.69 to me 80 006500 0 deny tcp from 192.168.0.63 to me 80 010000 0 allow tcp from 192.168.0.0/16 to me 21 010100 0 deny tcp from any to me 21 011000 0 allow tcp from 212.58.X.X to me 1433 via dc1 (ip intentionally hided) 011100 0 deny tcp from any to me 1433 via dc1 65000 5467 3180867 allow ip from any to any 65535 4654 322885 deny ip from any to any - Natd is diverting port 1433 to an internal machine. When I try with a different ip address on Internet than 212.58.x.x, and I can easily get connect to directed servers' 1433 port. I'm sure that I'm missing something, but I can not recognize what it is at the moment. Any help will be appreciated.

usb modem howto for newbie
Hello, I want to use a USB modem on FreeBSD 4.7-STABLE. First I do not know where to start. Is there any how-to pages? I looked at umodem.c file. There is not so much explanations in the code. I searched the archieves for a starting point. I could not find any helpful message for me. Here is what I could manage: kldload usb kldload umodem ls -l /dev/usb* crw-rw 1 root operator 108, 255 11 Eki 22:33 /dev/usb crw-rw 1 root operator 108, 0 11 Eki 22:33 /dev/usb0 crw-rw 1 root operator 108, 1 19 Kas 19:27 /dev/usb1 usbdevs -v Controller /dev/usb0: addr 1: self powered, config 1, UHCI root hub(0x), Intel(0x), rev 1.00 port 1 powered port 2 addr 2: power 100 mA, config 1, USB Communicator(0x7554), STMicroelectronics(0x0483), rev 1.01 Regards, Ertan Kucukoglu To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
MSN voice conversation + NATD problem.
Hello, My system is a FreeBSD 4.7-STABLE. I use dial-up internet connection. I wanted to setup one machine that can make voice connections over natd. My /etc/natd.conf looks like below: ozlerplastik@ertank ~ cat /etc/natd.conf log yes same_ports yes dynamic yes #MSN talk ports redirect_port tcp ertank:6901 6901 redirect_port udp ertank:6901 6901 My command line is natd -n tun0 -f /etc/natd.conf. ertank is in my hosts file and has a static 192.168.0.20 ip no. When I try to make voice connection to other machine I just can not connect. We tried netmeeting too. It uses same MSN ports. And, under netmeeting, other end see my ip number as 192.168.0.20. I do not know why. But, I guess the problem is this ip no. It can not reach my machine with this ip and connection just timeouts. Is there anybody who managed to make voice conversations over natd under FreeBSD? I need help about it.

ls shows hidden files when used by root
Hi all, When I su to root or login as root from console. ls shows hidden files, too. No matter I use ls -a or ls result is same: [root@escalade ~]ls .ICEauthority .ncrecent a.out .Xauthority .pinerc book .addressbook.profiledeneme .addressbook.lu .prx7p0lvM example_footer.php .bash_history .prxLSQn7i example_head.php .cpan .sshftp .cshrc .twmWp73RS lazim .fvwm .twmlpE18u mail .history.xinitrcmbox .klogin .xsession-errors muratsyslog.c .login .xsmGlMH9k nohup.out .mozilla.xsmKYc0tn rbin .mysql_history XF86Config sources [root@escalade ~]ls -a . .mysql_history a.out .. .ncrecent book .ICEauthority .pinerc deneme .Xauthority .profile example_footer.php .addressbook.prx7p0lvM example_head.php .addressbook.lu .prxLSQn7i ftp .bash_history .sshlazim .cpan .twmWp73RS mail .cshrc .twmlpE18u mbox .fvwm .xinitrc muratsyslog.c .history.xsession-errorsnohup.out .klogin .xsmGlMH9k rbin .login .xsmKYc0tn sources .mozillaXF86Config [root@escalade ~] Is there a way to change this behaviour? I do not wish to see hidden files as root. When I need I could always use ls -a. I could not find a solution in ~/.csh file and /etc/csh.cshrc.
