Re: Bandwidth Problems with Freebsd 5.x
Donald J. O'Neill a écrit : I guess you're right to say there's a misunderstanding. Ok I understand. I would want to say on this post that I made tests from the BSD box to a Debian box, both located on the 100 Mbits/s network. And I made others tests between the same BSD box (still located on the 100 Mbits/s network) and my home computer behind my ADSL Line.

Re: Bandwidth Problems with Freebsd 5.x
Hello Everybody, I made lots of searches on the Internet and I found something about the option net.inet.tcp.inflight.enable. If I set this value to 0, my bandwitdh problems are resolved. Does anybody knows something about this options and why can it be the origin of this problem ?

Mathieu CHATEAU a écrit : Are the debian freebsd on the same segment ? if so, are they using the same router/gateway ? No, there is the same CISCO Router between the two boxes. did you customize/set up things, like ipfw or set specific things via sysctl ? I tried to modify the tcp window size but the problem is stille here. What tcp trace will be useful to understand this problem ?

Danial Thom a écrit : It seems unlikely that he'd get good throughput in one direction if the link was hosed. One dropped packets and you're shot. The easy way to test this is to eliminate the switch..hook the Freebsd box directly to the linux box. Impossible to do that because the boxes are rented by an hosting company. ptitoliv ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I made the same tests on another network (same architecture but on a different hosting service network) On one side there is a Debian Sarge 3.1 On the other side there is a FreeBSD 5.4 Did you use FTP or ssh?

Re: Bandwidth Problems with Freebsd 5.x
Donald J. O'Neill a écrit : Maybe, but not to the internet on an 1.5Mb/s connection. Your aDSL line is only good for at most 1.5M and that's not guaranteed to happen all the time. There are a lot of things that go on to throttle that. At home I can connect between computers at 100 Mb/s, so what. I can't connect to the internet at faster than what's capable of being supplied by the ISP. I think there is a misunderstanding : boxes are not on my ADSL line but on a datacenter with 100 Mbits/s connectivity. When I say the Debian is able to make a 5 MB/s connexion it is not with my adsl line but another server located on the internet.

Mathieu CHATEAU a écrit : try this: ping -c 1000 -s 1500 IP_TO_PING wait for the 1000 ping to go trough. You should not have more than 0,5% of loss (is the servers aren't overload). If it's more or equal than 0,5%, it comes from the network (cables or switches fault). Each host would be in 100 full (via autoselect to be sure the conf is ok on the switch). I made the tests on the two boxes = 0 % packet loss. I man an other interesting test. I try to transfert between the BSD Box and a server located at home behind my 1MB/s ADSL Line. Here are the results : FreeBSD box = Workstation at home : 300 kB/s Debian box on the same network = Workstation at home : 950 kB/s. This test confirms cleraly that there is a problem with the BSD, I guess. Could it be a bug from the VR driver ?

Bandwidth Problems with Freebsd 5.x
Hello everybody, I am writing here because I have a problem with network on freebsd 5.3 and 5.4. The machines are pluged in a 100 Mbit/s with via rhine network cards. On this same LAN I have a Debian Sarge computer. When I try to transferts big files beetween the FreeBSD and the Debian, I see that I have an assymetric bandwith : From Debian to BSD : No problem. The bandwitdh is OK : About 8 MBytes/s which is normal for a LAN I guess. From BSD to Debian : The bandwidth is quite awful = Beetween 300 KBytes/s to 1Mbyte/s. Network have been changed and the problem is still the same. So I thought it was a network problem. Then I installed an other FreeBSD on a different computer and plugged it in a completely different network and the problem is still here. That's why I think there is a thing to configure on the BSD system but I don't know why. That's why I am looking here for someone who knows this problem and who will be able to help me.

Mathieu CHATEAU a écrit : what about netstat -e on each host ? (looking for errors) no errors detected are you on swicthes ? Are the switches port on auto or forced ? I don't know exactly : the servers are hosted by a company. So I think they are in autoselect mode. when doing an ifconfig -a, are you in 100 full duplex ? Yeah and I tried to forced in all possibles modes. (10/100 and half/full duplex) Are you using proftpd /wuftpd ? Proftpd but I made some new tests with HTTP and SCP and it is the same problem.

Thank you for your answers Best Regards, ptitoliv Are you doing GET from each machine, or comparing GET to PUT? Get has always been a lot faster then PUT. I tried GET and PUT from the two servers and the problem is still the same. Put a monitor on the LAN and look for weird sending patterns. The 4.x FTP servers will stop altogether if you set the window under 1500 bytes. I don't know if its the server app or the stack, but its probably the specific application, as HTTPD seems not to have such problems. The problem still exists with HTTP and SCP requests. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Window Scaling
Hello everybody, I have got 2 dedicated servers located on the same network. 1 is running on FreeBSD and the other under Linux Debian. The problem is that on the BSD box, it is impossible to have a transfer rate higer than 200 kB/s with one connection. If I create simultaneous connections, I can reach more higher transfer rates. On my Debian Box, I can reach easily 900 KB/s with only one connection. I have heard about TCP Window size and Window scaling. Do you think that it is possible to modify parameters on the BSD box in order to reach the same transfer rates than the Debian box with only one connection ? Thank you for your answers.

Resizing /var
Hello everybody, I have a big problem on a FreeBSD 5.3 Box. It is an hosted server installed by an hosting service. But I didn't know what they smoke when they have installed the system but they sized the /var filesystem only to 200 MB which is not sufficient for my needs. I used an emergency solution which was to transfer some datas on /usr like databases but I am afraid that the problem will come back. So I am asking here if there is any solution to transfer free space from ./usr to /var. But there are some constraints : - I have no free unpartitioned space available - I can't format any partition because and I can't loose datas Is there any solution with some BSD tools in order to solve this problem ?
