Re: Network Problem in FreeBSD 6.2-RELEASE-p5
I've already checket with sockstat.
Yes "net.inet.tcp.blackhole: 0" this is my net.inet.tcp.blackhole value
"0"..
I don't know how ti fix this.. I try to migrate to FreeBSD 5.5 but when
build the kernel of fbsd-5.5 I have some errors and back again to the
6.2...backup kernel..

netstat isn't the best way to figure this out. It can be confusing.
Try sockstat(1).

Check them after the reboot, using the sysctl(8) command and the
particular sysctl.

So check it:
$ sysctl net.inet.tcp.blackhole
net.inet.tcp.blackhole: 0
$

If nothing else affects it, yes. But check to be sure.

Re: Network Problem in FreeBSD 6.2-RELEASE-p5
Is the FreeBSD machine performing NAT for the Windows box? extazyti: yes with PF firewall. (But I don't have this problem before re-build my world+kernel (my last fbsd was fbsd6.2-STABLE. But this problem exist again in fbsd6.2-STABLE when I have build option ot drop TCP+SYN and have some bug..I donk know what exactly)) Are you saying that this is a second problem? extazyti: YES. because I think limmiting my connectins is normal when I have "net.inet.tcp.blackhole=2" but Now I haven't this sysctl option and this is problem again. How are you doing the scan, and how do you know the ports are not really open? extazyti: I use PortScan with a delay MS - 20 (He sends TCP4-sockets) and ports It's not really open because there is no program to open random ports with this values and I use the netstat command.

Which sysctl? extazyti: ALL, I put "#" before all texts in my sysctl.conf and reboot my system.

Network Problem in FreeBSD 6.2-RELEASE-p5
Hi, I have a serious problem with my network. I have connected 2 PC's, 1 - FreeBSD, 2 - Windows XP. The problem is follow - My FreeBSD limmiting connections , I cannot open more 224 TCP4-Sockets in my Windows Box. When I downloading torrent file, I cannot create more connections to the web, and while this time I can't open for example - web sites. Tow problem who worry myself is when I scan a my freebsd box or other "server" for open ports its FAKE show me: 81 82 ,83 ,465,463 and other ports open.. but It's FAKE .. it's not really open.. I Cleared my sysctl, and test, cleared my firewall and test, re-build my kernel with any options changed and test again.. Just don't Work :(( I have use PF firewall and FreeBSD 6.2-RELEASE-p5. I Think this problem is from "net.inet.tcp.blackhole=2" in my sysctl because it's work before i do sysctl -w net.inet.tcp.blackhole=2.. but when back this option to value = 0 this problem is stay there.. and no restarts or re-build my kernel can fix this..or maybe be wrong to this supposition.
