Often once there are errors, they grow exponentially because of retransmission etc. You should try to isolate the exact conditions you have when you see the traffic flow degrade. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Jeffrey P. Toth wrote: Thank you for your response Ion-Mihai, On the router question, no, the router is a separate device, a D-Link 504H but is a loaner while my D-Link 804HV is in the shop. After changing them out is when I discovered I had problems. Apparently the DL804 handled whatever the problem was without a complaint. Yes I have been through setup a few times. So far all I have been able to do is take the server off-line. I have also looked up setup for NATD and I think I can enable it but would not be able to write the firewall rules for it to read yet, as I understand needs to be done. I also had a little help with setup originally and I know there is something of a firewall setup but without know what exactly I would be afraid of interfering with what is there and making a mess of it. Sorry I am such a non-user. Jeff Jeff, I've been reading this thread and I think you need to start from the beginning. I am going to make a broad assumption that your D-Link is set up correctly and that it *is* a sort of broadband router that does NAT and has DHCP services. This means that the D-Link should be somehow connected to your DSL modem and/or Cable modem (unless you are using some other sort of connection - I couldn't find the 504H on D-Link's site, but was able to find the 804HV and am *again* assuming that it is similar). So here is the assumption list: - Your D-Link is capable of doing NAT and DHCP - You can ping the D-Link from your FreeBSD box (Win box, etc.) - if you can't STOP - this is your first problem. - Your router's internal address is 192.168.0.1 with a netmask of 255.255.255.0 - You have chosen to statically assign your inside machines with addy's (although you could also get the addy assignment via DHCP from the D-Link, you may have chosen to go the static route for other reasons). On the FreeBSD box: in rc.conf you should keep: ifconfig_xl0=inet 192.168.0.150 netmask 255.255.255.0 # -- no other machine on the network should have this address defaultrouter=192.168.0.1 Assigning an address to rl0 is irrelevant - also, make sure that that interface is unplugged from your network. Make sure the xl0 interface is plugged in correctly. For now, also make sure the following is true: natd_enable=NO firewall_enable=NO Save rc.conf Now, take a look at resolv.conf. It should show something like: nameserver 192.168.0.1 or the address of a nameserver you know is valid. Get rid of any other lines for now - you can simply comment them out by beginning the line with #. Save resolv.conf Although there are ways around this, reboot the machine. Once back up and running, you should be able to ping the router and ping an address like yahoo.com. If you can't ping a website outside your internal network - i.e. Yahoo's - then there is a problem probably related to the D-Link. On every machine, you should (basically) have the following configuration: IP: 192.168.0.x (NOT 1 or any address that you have used with another machine) netmask: 255.255.255.0 gateway: 192.168.0.1 DNS: 192.168.0.1 (or other valid DNS cache server). Since you are not doing NAT or firewalling on the FreeBSD machine, there is no need to enable them. If you eventually want to do firewalling directly on the FreeBSD box, then you can enable it and configure it after you have solved your networking problems. I would recommend simply allowing the IP addy's to be assigned via DHCP, though. On FreeBSD, you simply put: ifconfig_xl0=dhcp in rc.conf and get rid of the other config info. Also, leave the firewall and nat off. In resolv.conf you can comment everything out with # as it will be assigned dynamically by the dhcp server. This *should* get you going...

The server is online and working I just cannot seem to figure out why I cannot use http on the box and suspect that is the same reason the other computers on the network cannot access any of the sites on the FreeBSD machine without causing a freeze up. So you cannot access any web page *from* that box either on that box and away ? Please be clear. And when you try to access a page _on_ the box it freezes ? Maybe you have a firewall in between somewhere somehow ? If you're machine is freezing the you have to dig *this* problem. Did you played with sysctl or kernel settings ? Does ftp from or to the box work ? How much RAM do you have ? Did you disable swap ? Do the logs say anything ? I cannot acces any page on the FreeBSD box from the box itself or from any computer on the newtowrk. I can access all other websites outside of the network. After I attempt to access a page on the FreeBSD box from the box or one of the other computers on the netowork, at timeout the router freezes and goes offline. A power reboot fixes till the next time I try to access via http or ftp. If I connect up my XP computer through my dial up account removing it from the router, then I am on different network and I have no problem accessing any of the sites or ftp'ing into the box. I have not done anything with sysctl or kernel settings FTP works from outside the box but not from within the network. I have 256 Megs opf RAM Disable Swap? Looking in the logs httpd-error.log , httpd-access.log, debug.log, ftpd, dmesg.today, security, and messages I find nothing about any errors relating to the problem. In fact I don't even get a log where it tried to access the box in httpd-access.log Is this what you mean by not putting the text ontop and far as I can tell the setting says the message is wrapped 72 characters. did it work this time? Thanks for all, Jeff Do I need to add all the websites to the hosts file? Only if you what to access the by name locally and they are Name Based on apache in which case you have to add them to the hosts of all your computers or setup a dns server. Or the static IP of the box, xxx.xxx.xxx.150? No. Or maybe add the IP of the router? No. The host file contains these items as setup: 127.0.0.1 localhost localhost.name-of box.com 203.122.142.24 name-of-box.com. Replace name-of-box with the actual name of the box.

I think it should be: ifconfig_xl0=xxx.xxx.xxx.xxx#static IP address ifconfig_rl0=inet 192.168.0.150 netmask 255.255.255.0 Well, I don't understand if you use you FreeBSD box as a router or not. If yes, then you should have something like: hostname=buh.cameradicommercio.ro ifconfig_rl0=inet 81.196.25.19 netmask 255.255.255.0 ifconfig_rl1=inet 192.168.0.1 netmask 255.255.255.0 defaultrouter=81.196.25.1 where rl0 would be your outside interface connencted to your upstream provider's router with ip address 81.196.25.1 and rl1 would be the inside interface connected to a hub/switch with the internal machines. You would also want to use natd on the router, because 192.168/24 is a private address space. So you would add to you rc.conf: natd_enable=YES natd_interface=rl0 firewall_enable=YES firewall_type=OPEN You need FIREWALL=YES for natd to work.

So you cannot access any web page *from* that box either on that box and away ? Please be clear. And when you try to access a page _on_ the box it freezes ? Maybe you have a firewall in between somewhere somehow ? If you're machine is freezing the you have to dig *this* problem. Did you played with sysctl or kernel settings ? Does ftp from or to the box work ? How much RAM do you have ? Did you disable swap ? Do the logs say anything ? Do I need to add all the websites to the hosts file? Only if you what to access the by name locally and they are Name Based on apache in which case you have to add them to the hosts of all your computers or setup a dns server. Or the static IP of the box, xxx.xxx.xxx.150? No. Or maybe add the IP of the router? No. The host file contains these items as setup: 127.0.0.1 localhost localhost.name-of box.com 203.122.142.24name-of-box.com. Replace name-of-box with the actual name of the box.

OK, so it seems it isn't a basic networking issue, but rather a problem talking to your Web server running on your FBsd box. You mentioned some kind of firewall. The 'unexpected network error' could be due to a firewall, OR to not having any web server running on your box. 1- Is your web server process running? Assuming you are using apache from the ports collection, what does apachectl status show you (run in your FreeBSD server) ? 2- If it's a firewall, then you should open incoming TCP traffic to port 80 (and 443 if you plan to serve HTTPS). You could post here the contents of (if they exist) to help us help you: - /etc/rc.conf - /etc/ipf.rules - /etc/ipnat.rules - if you have a line reading firewall_type=/path/to/file, please also include that file ( of course, feel free to replace your public IP with something else to protect your privacy) 3- you could have tcpwrappers setup , blocking tcp traffic - I don't know from the top of my head how to check for this --someone else may want to. 4- or..in a strange setup, you may have apache running from your inetd, and have either inetd not setup to serve it properly OR actively blocking (tcp wrappers again) Do I need to add all the websites to the hosts file? Or the static IP of the box, xxx.xxx.xxx.150? if you have dns setup, u shouldn't need hosts file. Do you have DNS setup and working? can you ping your server by name rather than by IP only? Just cannot seem to find what affects this problem. too many things i'd say ;-) Cheers from Sydney, -- Norberto Meijome | freebsd at meijome dot net | numard at meijome dot net Everything is interesting if you go into it deeply enough. - Richard Feynman ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Network Help
Given your current network configuration as I understand it, there's no reason for running NAT on your FBSD box so don't even go there. Is your router blocking http either inbound or outbound (port 80) ? Why aren't you using dhclient to get the ip address for all your computers dynamically from the router? Does /etc/resolv.conf have any information in it? On Sunday 09 May 2004 10:46 pm, Jeffrey P.
