• Patching Synaptics Driver In Ubuntu

  - by danben

  I've got an HP Envy with the new Synaptics Clickpad - the device is not supported out of the box by Ubuntu, so I downloaded this patch (https://patchwork.kernel.org/patch/67335/), applied it to synaptics.c in the linux kernel source, rebuilt the kernel and booted from it. Nothing changed. I'm new to Linux and don't know much about driver configuration; how can I check that the newly-produced synaptics.o file is actually being used somewhere? Or if it is obvious, what step did I leave out? Separately, I tried following the instructions in this thread: http://georgia.ubuntuforums.org/showpost.php?p=8989185&postcount=11 There, someone posted the patch along with a Makefile and instructions for installation. When I followed those, my mouse stopped working altogether. Not desirable, but at least I know it had some effect. The Makefile is posted below; I get the gist of what it's doing, but don't have enough knowledge to figure out why it would cause the device to stop responding entirely. obj-m := psmouse.o psmouse-objs := psmouse-base.o synaptics.o psmouse-$(CONFIG_MOUSE_PS2_ALPS) += alps.o psmouse-$(CONFIG_MOUSE_PS2_ELANTECH) += elantech.o psmouse-$(CONFIG_MOUSE_PS2_OLPC) += hgpk.o psmouse-$(CONFIG_MOUSE_PS2_LOGIPS2PP) += logips2pp.o psmouse-$(CONFIG_MOUSE_PS2_LIFEBOOK) += lifebook.o psmouse-$(CONFIG_MOUSE_PS2_TRACKPOINT) += trackpoint.o psmouse-$(CONFIG_MOUSE_PS2_TOUCHKIT) += touchkit_ps2.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules install: @cp psmouse.ko /lib/modules/$(shell uname -r)/kernel/drivers/input/mouse/

• howto configure proxy.conf for mod_proxy, apache2, jetty

  - by Kaustubh P

  Hello, This is how I have setup my environment, atm. An apache2 instance on port 80. Jetty instance on the same server, on port 8090. Use-Case: When I visit foo.com, I should see the webapp, which is hosted on jetty, port 8090. If I put foo.com/blog, I should see the wordpress blog, which is hosted on apache. (I read howtos on the web, and installed it using AMP.) Below are my various configuration files: /etc/apache2/mods-enabled/proxy.conf: ProxyPass / http://foo.com:8090/ << this is the jetty server ProxyPass /blog http://foo.com/blog ProxyRequests On ProxyVia On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost On ProxyStatus On /etc/apache2/httpd.conf: LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_balancer_module /usr/lib/apache2/modules/mod_proxy_balancer.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so I have not created any other files, in sites-available or sites-enabled. Current situation: If I goto foo.com, I see the webapp. If I goto foo.com/blog, I see a HTTP ERROR 404 Problem accessing /errors/404.html. Reason: NOT_FOUND powered by jetty:// If I comment out the first ProxyPass line, then on foo.com, I only see the homepage, without CSS applied, ie, only text.. .. and going to foo.com/blog gives me a this error: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /blog. Reason: Error reading from remote server I also cannot access /phpmyadmin, giving the same 404 NOT_FOUND error as above. I am running Debian squeeze on an Amazon EC2 Instance. Question: Where am I going wrong? What changes should I make in the proxy.conf (or another conf files) to be able to visit the blog?

• Upgrade Debian to unstable on VirtualBox: udev problem

  - by Ken

  I'm running Debian stable on VirtualBox on Windows Vista 64-bit Ultimate. It's been running great, but I needed some newer packages, so I put sid in my sources.list to upgrade to unstable (as I've done a dozen times on various Linux boxes over the years). When I upgraded, something went screwy and it asked me to run apt-get -f install to fix them, which gave this: (Reading database ... 77846 files and directories currently installed.) Preparing to replace udev 0.125-7+lenny3 (using .../archives/udev_151-3_amd64.deb) ... Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED feature is disabled in the running kernel. Please upgrade your kernel before or while upgrading udev. AT YOUR OWN RISK, you can force the installation of this version of udev WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file. There is always a safer way to upgrade, do not try this unless you understand what you are doing! dpkg: error processing /var/cache/apt/archives/udev_151-3_amd64.deb (--unpack): subprocess new pre-installation script returned error exit status 1 insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). Errors were encountered while processing: /var/cache/apt/archives/udev_151-3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I have the VirtualBox extensions installed, and it looks like the udev install doesn't know what to make of them. But I don't know exactly where/how they're installed (I just ran the VBoxLinuxAdditions-amd64.run script, basically), so I don't know how to disable them. Any ideas? Thanks!

• Pinging an external server through OpenVPN tunnel doesn’t work

  - by qdii

  I have an OpenVPN server and a client, and I want to use this tunnel to access not only 10.0.8.0/24 but the whole internet. So far, pinging the server from the client through the tun0 interface works, and vice versa. However, pinging www.google.com from the client through tun0 doesn’t work (all packets are lost). I figured that I should configure the server so that any packet coming from tun0 in destination of the internet be forwarded, so I came up with this iptables config line: interface_connecting_to_the_internet='eth0' interface_openvpn='tun0' internet_ip_address=`ifconfig "$interface_connecting_to_the_internet" | sed -n s'/.*inet \([0-9.]*\).*/\1/p'` iptables -t nat -A POSTROUTING -o "${interface_connecting_to_the_internet}" -j SNAT --to-source "${internet_ip_address}" echo '1' > /proc/sys/net/ipv4/ip_forward Yet, this doesn’t work, the packets are still lost and I am wondering what could possibly be wrong with my setup. Some details: ip route gives on the server: default via 176.31.127.254 dev eth0 metric 3 10.8.0.0/24 via 10.8.0.2 dev tun0 10.8.0.2 dev tun0 proto kernel scope link src 10.8.0.1 127.0.0.0/8 via 127.0.0.1 dev lo 176.31.127.0/24 dev eth0 proto kernel scope link src 176.31.127.109 ip route gives on the client: default via 192.168.1.1 dev wlan0 proto static 10.8.0.1 via 10.8.0.5 dev tun0 10.8.0.5 dev tun0 proto kernel scope link src 10.8.0.6 127.0.0.0/8 via 127.0.0.1 dev lo scope link 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.109 client uses wifi adapter wlan0 and TUN adapter tun0. server uses ethernet adapter eth0 and TUN adapter tun0. the VPN spans on 10.0.8.0/24 both client and linux are using Linux 3.6.1.

• Regular Windows 7 BSOD with Shrew VPN client

  - by Junto

  The Shrew VPN client appears to be a good alternative to the Cisco VPN Client on x64 Windows 7. However, since installing it I've seen fairly regular BSODs.

Superuser appears to have several recommendations for the Shrew VPN Client as an alternative to the Cisco VPN client on 64 bit machines, so I wondered if anyone here has seen this problem and possibly found a solution to the problem? I've decided to run the VPN client under Windows 7 compatibility mode for the moment (Vista SP2) with administrator privileges to see if it makes a difference. Oddly, the VPN doesn't necessarily need to be connected. I've noticed it when browsing using Google Chrome and Internet Explorer, usually when I open up a new tab. If it carries on I think I'll be forced to shell out the 120 EUR for the NCP Client instead.

• OpenVZ Can't initialize containers after install

  - by Tonino Jankov

  I have installed OpenVZ on centos 6 on a dedicated server. I followed quick installation guide on openvz wiki. After installing thru yum, I don't know why, but grub.conf wasn't automatically updated to accomodate new kernel, so I had to do it manually. I edited grub.conf, added openvz kernel and rebooted - it went fine. Server went up into openvz kernel and it worked, it started openvz service byitself. But after I created a container, added IP to it and attempted to start it, I couldn't. Here is the output from the shell: [root@cloud2 ~]# vzctl start 86 Starting container ... Container is mounted Container start failed (try to check kernel messages, e.g. "dmesg | tail") Container is unmounted [root@cloud2 ~]# dmesg | tail [ 1973.401596] CT: 86: failed to start with err=-105 [ 2107.113850] Failed to initialize the ICMP6 control socket (err -105).

• Ubuntu VM "read only file system" fix?

  - by David

  I was going to install VMWare tools on an Ubuntu server Virtual Machine, but I ran into the issue of not being able to create a cdrom directory in the /mnt directory. I then tested to see if it was just a permissions issue, but I couldn't even create a folder in the home directory. It continues to state that it is a read only file system. I know a little about Linux, and I'm not comfortable with it yet. Any advice would be much appreciated.

• iptables advanced routing

  - by Shamanu4

  I have a Centos server acting as a NAT in my network. This server has one external (later ext1) interface and three internal (later int1, int2 and int3). Egress traffic comes from users via int1 and after MASQUERADE goes via ext1. Ingress traffic comes from ext1, MASQUERADE, and goes via int2 or int3 according to static routes. | ext1 | x.x.x.x/24 +---------|----------------------+ | | | Centos server (NAT) | | | +---|------|---------------|-----+ | | | int1 | | int2 | int3 10.30.1.10/24 | | 10.30.2.10/24 | 10.30.3.10/24 ^ v v 10.30.1.1/24 | | 10.30.2.1/24 | 10.30.3.1/24 +---|------|---------------|-----+ | | | | | | | v v | | ^ -Traffic policer- | | |_____________ | | | | | +------------------|-------------+ | 192.168.0.1/16 | | Clients 192.168.0.0/16 The problem: Egress traffic seems to be dropped after PREROUTING table. Packet counters are not changing on MASQUERADE rule in POSTROUTING. If I change the routes to clients causing the traffic go back via int1 - everything works perfectly. current iptable configuration is very simple: # cat /etc/sysconfig/iptables *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -I INPUT 1 -i int1 -j ACCEPT -A FORWARD -j ACCEPT COMMIT *nat -A POSTROUTING -o ext1 -j MASQUERADE # COMMIT Can anyone point me what I'm missing?

• Intermittent NFS lockups on Isilon cluster

  - by blackbox222

  We have an Isilon cluster with 8 IQ 12000x nodes which exports storage via several NFS shares for a handful of Linux and Solaris clients. There is a Linux system that has one of these NFS filesystems mounted. I/O to this filesystem is moderately heavy from the Linux system. Every 3-4 weeks (it's not on any kind of discernible schedule, and sometimes is more/less frequent than this), we notice that all activity ceases on this NFS mount (the process hangs, as if the network stopped working so process is stuck in uninterruptible sleep) - 30 minutes later, the share recovers and things continue to work normally. The kernel log from the affected machine is as follows: Dec 3 10:07:29 redacted kernel: [8710020.871993] nfs: server nfs-redacted not responding, still trying Dec 3 10:37:17 redacted kernel: [8711805.966130] nfs: server nfs-redacted OK relevant /etc/fstab line: nfs-redacted:/ifs/nfs/export_data/shared/...redacted... /data nfs defaults 0 0 I've checked to see if there are any scheduled processes e.g. cron jobs, Isilon related functions e.g. snapshots, etc that might be causing these hangups but I can't seem to find anything. I'm also not aware of any network related issues or maintenance that would cause this. All of the lockups last almost exactly 30 minutes per the kernel logs. Perhaps someone has some suggestions I could try? (I considered a soft mount to avoid the problems associated with processes accessing the filesystem hanging; however am wary of the corruption that could result and it would not really solve the underlying issue anyway).

• Debugging apache seg fault with gdb

  - by Joyce Babu

  Apache on a production server of mine is seg faulting intermittently. I have enabled core dump option in apache configuration and have several dumped core files. Unfortunately, since it is a production server, apache or the loaded modules are not compiled with debug symbols. From what I understand, gdb cannot do much without debug symbols. Can I at least find out which module is causing the seg fault, without debug symbols? If so, how? Following is the output from a gdb backtrace (gdb) bt full #0 0xb7f1f832 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 No symbol table info available. #1 0xb7be82bc in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 No symbol table info available. #2 0xb771652a in ??

Does this mean that /lib/ld-linux.so.2 is causing the seg fault?

• Default IPv6 route on debian squeeze does not come up after boot

  - by Georg Bretschneider

  I have a problem with my default IPv6 route not coming up after boot on a Debian Squeeze system. This is my config (/etc/network/interfaces): # Loopback device: auto lo iface lo inet loopback iface lo inet6 loopback # device: br0 auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 88.198.62.xx broadcast 88.198.62.63 netmask 255.255.255.224 gateway 88.198.62.33 up route add -net 88.198.62.32 netmask 255.255.255.224 gw 88.198.62.33 br0 iface br0 inet6 static address 2a01:4f8:131:10x::2 netmask 64 gateway 2a01:4f8:131:100::1 up route -A inet6 add 2a01:4f8:131:100::1/59 dev br0 My inet comes up alright, but I have to exec the route command manually after boot to make IPv6 work. Otherwise I can't even reach my gateway. This is the output of ip -6 route show after boot: 2a01:4f8:131:10x::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 unreachable fe80::/64 dev lo proto kernel metric 256 error -101 mtu 16436 advmss 16376 hoplimit 4294967295 fe80::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 I already tried it with: up ip -6 route add 2a01:4f8:131:100::1 dev br0 up ip -6 route add default via 2a01:4f8:131:100::1 dev br0 in /etc/network/interfaces, but with the same results. If I execute those commands manually on my shell, everything starts working nicely. And yes, I tried with post-up instead of up, too. Only other changes I made was to activate ip forwarding for IPv6, because I want to run some LXC containers on that system.

• How do I mount an external USB hard drive on my Sheevaplug?

  - by James

  I've acquired a Sheevaplug running - I think - Ubuntu. I'd like to mount an external USB hard drive, but I don't know the name of the device that needs mounting. When I list the devices under /dev, a long list is produced. How do I find out which device listed needs to be mounted? Update: When I run dmesg after plugging the device in, I see the following at the end: usb 1-1: new high speed USB device using ehci_marvell and address 6 usb 1-1: device not accepting address 6, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 7 usb 1-1: device not accepting address 7, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 8 usb 1-1: device not accepting address 8, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 9 usb 1-1: device not accepting address 9, error -71 And when I view /var/log/messages, I can see this: Sep 23 21:26:03 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:04 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Unfortunately, I don't know what these mean.

• Advertise a subnet route with radvd

  - by Thomas Berger

  we have set up a small IPv6 Testing network. The setup looks like this: ::/0 +----------+ | Firewall | Router to the public net +----------+ | 2001:...::/106 | +----------+ +-------| SIT GW | sit Tunnel gatway to the some test users | +----------+ | +----------+ | Test Sys | Testsystem +----------+ The idea is to advertise the default route from the firewall and the route for the SIT subnets from the sit gateway. The configurations for radvd are: # Firewall interface eth0 { AdvSendAdvert on; route ::/0 { }; }; # SIT Gatway interface eth0 { AdvSendAdvert on; route 2001:...::/106 { }; }; We have captured the adv. packages with tcpdump and the packages looks good. We see a default route from the fw, and the subnet route from the SIT gatway. But if we look on the testsystem there are two default routes over both gateways. There is no subnet route. The routing does not work of course. Here the routes we get: 2001:.....::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::baac:6fff:fe8e:XXXX dev eth0 proto kernel metric 1024 expires 0sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::e415:aeff:fe12:XXXX dev eth0 proto kernel metric 1024 expires 0sec mtu 1500 advmss 1440 hoplimit 64 Any Idea?

• Gigabit network limited to 25MB/s by CPU. How to make it faster?

  - by netvope

  I have a Acer Aspire R1600-U910H with a nForce gigabit network adapter. The maximum TCP throughput of it is about 25MB/s, and apparently it is limited by the single core Intel Atom 230; when the maximum throughput is reached, the CPU usage is about 50%-60%, which corresponds to full utilization considering this is a Hyper-threading enabled CPU. The same problem occurs on both Windows XP and on Ubuntu 8.04. On Windows, I have installed the latest nForce chipset driver, disabled power saving features, and enabled checksum offload. On Linux, the default driver has checksum offload enabled. There is no Linux driver available on Nvidia's website. ethtool -k eth0 shows that checksum offload is enabled: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: off The following is the output of powertop when the network is idle: Wakeups-from-idle per second : 61.9 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 90.9% (101.3) <interrupt> : eth0 4.5% ( 5.0) iftop : schedule_timeout (process_timeout) 1.8% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.9% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.5% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) And when the maximum throughput of about 25MB/s is reached: Wakeups-from-idle per second : 11175.5 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 99.9% (22097.4) <interrupt> : eth0 0.0% ( 5.0) iftop : schedule_timeout (process_timeout) 0.0% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.0% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.0% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) Notice the 20000 interrupts per second. Could this be the cause for the high CPU usage and low throughput? If so, how can I improve the situation? The other computers in the network can usually transfer at 50+MB/s without problems. And a minor question: How can I find out what is the driver in use for eth0?

• How To Boot with "mem=1024m" Argument using GRUB - Ubuntu 10.04

  - by nicorellius

  I am still working on this question. This new one is a different question so I thought it would be good to post a new question. Is this the proper protocol or should I have just edited the other question? I'm running Ubuntu 10.04 with the kernel 2.6.32-22-generic on a Toshiba Satellite laptop. When I enter the GRUB menu (I have Ubuntu 9.10 installed as well), I can choose which kernel to boot. I use scroll down to the one I want and press "e" and I expect to be able to enter mem=1024m and force the kernel to use this much memory. But when I run cat /proc/meminfo or look in the process manager after booting wth this argument I still see all the RAM: ~2 GB. Am I using this boot argument incorrectly? The boot configuration (before I add anything) looks like this: insmod ext2 set root=(hd0,1) search --no-floppy --fs-uuid --set 10270f21-1c42-494b-bd3f-813c23f6d\ 518 linux /boot/vmlinuz-2.6.32-22-generic root=UUID=10270f21-1c42-494b-b\ d3f-813c23f6d518 ro quiet splash initrd /boot/initrd.img-2.6.32-22-generic The way I did this was that I added the mem=1024m after the last line and pressed Ctrl+x (Emacs save and boot the kernel) and the system booted. I tried adding mem=1024m to the end and the beginning of this list and it appeared to not change the RAM allocation.
