I have problem with dummynet in FreeBSD 5.4 When i create any(10Mbit/s) pipe for my any host in local network, delay for this host rise from 1-3 ms to 15-20 ms, freebsd 5.3 i have not see something that pings before i add pipes ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3): 56 data bytes 64 bytes from 192.168.1.3: icmp_seq=0 ttl=125 time=2.314 ms 64 bytes from 192.168.1.3: icmp_seq=1 ttl=125 time=3.506 ms ^C --- 192.168.1.3 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/stddev = 2.314/2.910/3.506/0.596 ms ipfw pipe 3 config bw 10Mbit/s queue 3MB ipfw pipe 4 config bw 10Mbit/s queue 3MB ipfw a 3 pipe 4 ip from 192.168.1.3 to me ipfw a 3 pipe 3 ip from me to 192.168.1.3 pings after i add pipes ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3): 56 data bytes 64 bytes from 192.168.1.3: icmp_seq=0 ttl=125 time=13.902 ms 64 bytes from 192.168.1.3: icmp_seq=1 ttl=125 time=19.183 ms 64 bytes from 192.168.1.3: icmp_seq=2 ttl=125 time=19.651 ms 64 bytes from 192.168.1.3: icmp_seq=3 ttl=125 time=19.891 ms 64 bytes from 192.168.1.3: icmp_seq=4 ttl=125 time=19.458 ms ^C --- 192.168.1.3 ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max/stddev = 13.902/18.417/19.891/2.269 ms My Kernel achine i386 cpu I686_CPU ident AERO options SCHED_4BSD # 4BSD scheduler options INET # InterNETworking options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options MD_ROOT # MD is a potential root device options NFSCLIENT # Network Filesystem Client options NFSSERVER # Network Filesystem Server options NFS_ROOT # NFS usable as /, requires NFSCLIENT options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options SCSI_DELAY=15000 # Delay (in ms) before probing SCSI options KTRACE # ktrace(1) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options ADAPTIVE_GIANT # Giant mutex is adaptive. device apic # I/O APIC options VM_KMEM_SIZE_SCALE="1" options IPFIREWALL options IPFIREWALL_FORWARD options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=300 options IPFIREWALL_DEFAULT_TO_ACCEPT options IPDIVERT options DUMMYNET options NETGRAPH options NETGRAPH_ETHER options NETGRAPH_PPPOE options NETGRAPH_SOCKET options NETGRAPH_TEE options IPFILTER options IPFILTER_LOG options DEVICE_POLLING options TCPDEBUG options TCP_DROP_SYNFIN device isa device pci device fdc device ata device atadisk # ATA disk drives device ataraid # ATA RAID drives device atapicd # ATAPI CDROM drives options ATA_STATIC_ID # Static device numbering device atkbdc # AT keyboard controller device atkbd # AT keyboard device vga # VGA video card driver device splash # Splash screen and screen saver support device sc device agp # support several AGP chipsets device npx device pmtimer device cbb # cardbus (yenta) bridge device pccard # PC Card (16-bit) bus device cardbus # CardBus (32-bit) bus # Serial (COM) ports device sio # 8250, 16[45]50 based serial ports device miibus # MII bus support device fxp # Intel EtherExpress PRO/100B (82557, 82558) device rl # RealTek 8129/8139 device tl # Texas Instruments ThunderLAN device xl # 3Com 3c90x (``Boomerang'', ``Cyclone'') device loop # Network loopback device mem # Memory and kernel memory devices device io # I/O device device random # Entropy device device ether # Ethernet support device ppp # Kernel PPP device tun # Packet tunnel. device pty # Pseudo-ttys (telnet etc) device md # Memory "disks" device bpf # Berkeley packet filter Sorry for my English Thanks Wait for answer ---------------------------------------------------------------------- UARNet Volodymyr Pelekh Tel: +38 0322 97 91 16 E-mail mailto:vpeleh@mail.lviv.ua ----------------------------------------------------------------------
