hi, i'm using Hardy 2.6.24-17-generic (up to date) and i try to get better tcp speed (compare to winxp: i usually get about 5mb/s but only 1.5 with Hardy, on a 30mb cable connexion). So sysctl show me some warwing: o...@ubuntu:~$ sysctl -a | fgrep tcp error: permission denied on key 'kernel.sched_nr_migrate' error: permission denied on key 'kernel.cap-bound' error: permission denied on key 'kernel.cad_pid' error: permission denied on key 'net.ipv4.route.flush' error: permission denied on key 'net.ipv6.route.flush' net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_window_scaling = 0 net.ipv4.tcp_sack = 0 net.ipv4.tcp_retrans_collapse = 1 net.ipv4.tcp_syn_retries = 6 net.ipv4.tcp_synack_retries = 3 net.ipv4.tcp_max_orphans = 32768 net.ipv4.tcp_max_tw_buckets = 180000 net.ipv4.tcp_keepalive_time = 1800 net.ipv4.tcp_keepalive_probes = 9 net.ipv4.tcp_keepalive_intvl = 75 net.ipv4.tcp_retries1 = 3 net.ipv4.tcp_retries2 = 15 net.ipv4.tcp_fin_timeout = 30 net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_tw_recycle = 0 net.ipv4.tcp_abort_on_overflow = 0 net.ipv4.tcp_stdurg = 0 net.ipv4.tcp_rfc1337 = 0 net.ipv4.tcp_max_syn_backlog = 64 net.ipv4.tcp_orphan_retries = 0 net.ipv4.tcp_fack = 1 net.ipv4.tcp_reordering = 5 net.ipv4.tcp_ecn = 0 net.ipv4.tcp_dsack = 1 net.ipv4.tcp_mem = 390144 520192 780288 net.ipv4.tcp_wmem = 4096 65536 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_app_win = 31 net.ipv4.tcp_adv_win_scale = 2 net.ipv4.tcp_tw_reuse = 0 net.ipv4.tcp_frto = 2 net.ipv4.tcp_frto_response = 0 net.ipv4.tcp_low_latency = 0 net.ipv4.tcp_no_metrics_save = 1 net.ipv4.tcp_moderate_rcvbuf = 1 net.ipv4.tcp_tso_win_divisor = 3 net.ipv4.tcp_congestion_control = reno net.ipv4.tcp_abc = 0 net.ipv4.tcp_mtu_probing = 0 net.ipv4.tcp_base_mss = 512 net.ipv4.tcp_workaround_signed_windows = 0 net.ipv4.tcp_dma_copybreak = 4096 net.ipv4.tcp_slow_start_after_idle = 1 net.ipv4.tcp_available_congestion_control = reno net.ipv4.tcp_allowed_congestion_control = reno net.ipv4.tcp_max_ssthresh = 0 net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_sent = 120 net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_recv = 60 net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 432000 net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait = 120 net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait = 60 net.ipv4.netfilter.ip_conntrack_tcp_timeout_last_ack = 30 net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait = 120 net.ipv4.netfilter.ip_conntrack_tcp_timeout_close = 10 net.ipv4.netfilter.ip_conntrack_tcp_timeout_max_retrans = 300 net.ipv4.netfilter.ip_conntrack_tcp_loose = 1 net.ipv4.netfilter.ip_conntrack_tcp_be_liberal = 0 net.ipv4.netfilter.ip_conntrack_tcp_max_retrans = 3 net.netfilter.nf_conntrack_tcp_timeout_syn_sent = 120 net.netfilter.nf_conntrack_tcp_timeout_syn_recv = 60 net.netfilter.nf_conntrack_tcp_timeout_established = 432000 net.netfilter.nf_conntrack_tcp_timeout_fin_wait = 120 net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60 net.netfilter.nf_conntrack_tcp_timeout_last_ack = 30 net.netfilter.nf_conntrack_tcp_timeout_time_wait = 120 net.netfilter.nf_conntrack_tcp_timeout_close = 10 net.netfilter.nf_conntrack_tcp_timeout_max_retrans = 300 net.netfilter.nf_conntrack_tcp_loose = 1 net.netfilter.nf_conntrack_tcp_be_liberal = 0 net.netfilter.nf_conntrack_tcp_max_retrans = 3 error: permission denied on key 'fs.binfmt_misc.register' i hope to find a solution because i need realtime high speed for professional task. I can't find how to tune tcp parameters for better result. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21. + Architecture: i386 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: pulse 1929 F.... pulseaudio + CRDA: Error: [Errno 2] Aucun fichier ou dossier de ce type + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xfebfc000 irq 19' + Mixer name : 'Realtek ALC882' + Components : 'HDA:10ec0882,1043e601,00100101' + Controls : 44 + Simple ctrls : 25 + CurrentDmesg: + [ 20.335979] ppdev: user-space parallel port driver + [ 26.124005] eth1: no IPv6 routers present + [ 1741.597957] process `sysctl' is using deprecated sysctl (syscall) net.ipv6.neigh.default.retrans_time; Use net.ipv6.neigh.default.retrans_time_ms instead. + DistroRelease: Ubuntu 10.04 + HibernationDevice: RESUME=UUID=f4216733-a2b7-4818-9852-9bb41d54d87c + IwConfig: + lo no wireless extensions. + + eth0 no wireless extensions. + + eth1 no wireless extensions. + MachineType: ASUSTEK COMPUTER INC P5W DH Deluxe + NonfreeKernelModules: nvidia + Package: linux 2.6.32.14.15 + PackageArchitecture: i386 + ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-14-generic root=UUID=00c5de83-479c-4ab0-9b54-9af0a727175e ro quiet splash + ProcEnviron: + PATH=(custom, no user) + LANG=fr_FR.utf8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.32-14.20-generic + Regression: No + RelatedPackageVersions: linux-firmware 1.31 + Reproducible: Yes + RfKill: + + Tags: lucid + TestedUpstream: Yes + Uname: Linux 2.6.32-14-generic i686 + UserGroups: admin audio gdm pulse pulse-access + WifiSyslog: Feb 27 09:08:03 localhost kernel: [ 1741.597957] process `sysctl' is using deprecated sysctl (syscall) net.ipv6.neigh.default.retrans_time; Use net.ipv6.neigh.default.retrans_time_ms instead. + dmi.bios.date: 07/10/2008 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 2801 + dmi.board.asset.tag: To Be Filled By O.E.M. + dmi.board.name: P5W DH Deluxe + dmi.board.vendor: ASUSTeK Computer INC. + dmi.board.version: Rev 1.xx + dmi.chassis.asset.tag: Asset-1234567890 + dmi.chassis.type: 3 + dmi.chassis.vendor: Chassis Manufacture + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr2801:bd07/10/2008:svnASUSTEKCOMPUTERINC:pnP5WDHDeluxe:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP5WDHDeluxe:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: + dmi.product.name: P5W DH Deluxe + dmi.product.version: System Version + dmi.sys.vendor: ASUSTEK COMPUTER INC ** Attachment added: "AlsaDevices.txt" http://launchpadlibrarian.net/39848560/AlsaDevices.txt -- sysctl: permission denied https://bugs.launchpad.net/bugs/236558 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
