Hi, I'm experiencing something very strange. I have a LAN of 4.3 FreeBSD machines connected to internet through ethernet gateway. let's call them A, B, & C scp , ftp is really quick between A&B , but really slow between A&C , B&C C appears to be the problem. I can ftp files from C quicker to an external machine over the internet than I can over the LAN. Across LAN from C to A ------------------- ftp'ing 100 byte files from C to A at 1.8 MB/sec ftp'ing 500K files from C to A at 4KB/sec ftp'ing 50MB file .... transfer rate slows down to 3KB/sec and eventually stalls From the outside world across internet ---------------------------- ftp'ing 500K files from C to machine outside LAN accross internet at 30KB/sec !!! ftp'ing 50MB file from C to machine outside LAN accross internet at 30KB/sec !!! A - Old 10Mbit card B & C both have 2 x 10/100 Mbit cards, but I'm only using the first one in each case. My Hub is 10Mbit (Intel InBusiness) I think the problem is down to network cards, or configuration as 'top' shows little memory and CPU being used by C when I get the problem. C is also providing HTTP / FTP but I don't think its hung processes because a reboot doesn't help. How can I measure how fast each card will work at ??? Any comments or suggestions would be welcome Thanks Dave A reports ======= ed1: <NE2000 PCI Ethernet (RealTek 8029)> rev 0x00 int a irq 11 on pci0.8.0 ed1: address 00:00:21:c5:c7:ab, type NE2000 (16 bit) B reports ======= rl0: <RealTek 8139 10/100BaseTX> port 0xe800-0xe87f mem 0xec000000-0xec00007f irq 10 at device 9.0 on pci0 rl0: Ethernet address: 00:c0:df:22:49:4d miibus0: <MII bus> on rl0 rlphy0: <RealTek internal media interface> on miibus0 rlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto rl1: <RealTek 8139 10/100BaseTX> port 0xec00-0xec7f mem 0xec001000-0xec00107f irq 15 at device 10.0 on pci0 rl1: Ethernet address: 00:c0:df:22:46:b6 miibus1: <MII bus> on rl1 rlphy1: <RealTek internal media interface> on miibus1 rlphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto C reports ======= rl0: <RealTek 8139 10/100BaseTX> port 0xdc00-0xdcff mem 0xeffffe00-0xeffffeff irq 12 at device 10.0 on pci0 rl0: Ethernet address: 00:02:44:04:93:f1 miibus0: <MII bus> on rl0 rlphy0: <RealTek internal media interface> on miibus0 rlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto rl1: <RealTek 8139 10/100BaseTX> port 0xde00-0xdeff mem 0xefffff00-0xefffffff irq 10 at device 11.0 on pci0 rl1: Ethernet address: 00:02:44:04:93:c6 miibus1: <MII bus> on rl1 rlphy1: <RealTek internal media interface> on miibus1 rlphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
