• Mounting any Windows share from OS X 10.7.5 suddenly stopped working

  - by user2169619

  I have problem with mounting Windows network shares from my OS X 10.7.5 - it worked but it stopped and nothing helps and nothing in logs. Here what I get when trying to mount it manually: mount -t smbfs //10.0.0.7/d /tmp/test When doing sniffing with tshark - no packet it sent through and I get immediately return from the command: mount_smbfs: server connection failed: Unknown error: -1 Nothing in /var/log/syslog.log and /var/log/kern.log. The Finder does not work either - it throws an error that something is wrong (in czech thus I'm not sending the message here). I just cannot connect to any network shares. In virtual Windows 7 in Parallels Desktop I can connect successfully, but not within the network share (so the Win7 is behind OS X NAT) but only with its own IP address. The Windows server share is on the same network segment connected through switch. Any advice how to debug and what can be wrong? I spent hours to find solution on Google and here but no-one with this kind of problem and I do not know how to further debug it since there is no meaningful log / trace etc. I can ping 10.0.0.7 and I can connect to FTP server on 10.0.0.7 - the Windows machine (XP) has firewall completely turned off. The problem is that with tshark, I'm not seeing any packet sending to 10.0.0.7 so it's not even trying to reach the server.

• clocksource tsc unstable

  - by amorfis

  Ok, now I have real server fault ;) After some time from booting (about one minute) my server hangs. All I can do is hard reset. Then after restart in /var/log/kern.log I can find: Jul 29 22:38:57 leonidas kernel: [ 90.729598] longhaul: Failed to set requested frequency!

I tried disabling ACPI but it didn't help (but I noticed there was longer time before hanging). I can't change clock to hpet, because my system doesn't have such one.

• logrotate: neither rotate nor compress empty files

  - by Andrew Tobey

  i have just set up an (r)syslog server to receive the logs of various clients, which works fine. only logrotate is still not behaving as intending. i want logrotate to create a new logfile for each day, but only to keep and store i.e. compress non-empty files. my logrotate config looks currently like this # sample configuration for logrotate being a remote server for multiple clients /var/log/syslog { rotate 3 daily missingok notifempty delaycompress compress dateext nomail postrotate reload rsyslog >/dev/null 2>&1 || true endscript } # local i.e. the system's very own logs: keep logs for a whole month /var/log/kern.log /var/log/kernel-info /var/log/auth.log /var/log/auth-info /var/log/cron.log /var/log/cron-info /var/log/daemon.log /var/log/daemon-info /var/log/mail.log /var/log/rsyslog /var/log/rsyslog-info { rotate 31 daily missingok notifempty delaycompress compress dateext nomail sharedscripts postrotate reload rsyslog >/dev/null 2>&1 || true endscript } # received i.e. logs from the clients /var/log/path-to-logs/*/* { rotate 31 daily missingok notifempty delaycompress compress dateext nomail } what i end up with is having is some sort of "summarized" files such as filename-datestampDay-Day and corresponding .gz files. What I do have are empty files, which are eventually zipped. so does the notifempty directive is in fact responsible for these DayX-DayY files, days on which really nothing happened? what would be an efficient way to drop both, empty log files and their .gz files, so that I eventually only keep logs/compressed files that truly contain data?

• Why is my cron daemon is being killed every few minutes?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6 x64 on an OpenVZ virtual machine. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has at least 800 MB of free memory, and cat /proc/loadavg returns 0.22 0.13 0.04 so resources shouldn't be the issue. With cron running, free -m reports: total used free shared buffers cached Mem: 1024 211 812 0 0 0 -/+ buffers/cache: 211 812 Swap: 0 0 0 I also tried removing and reinstalling the cron package using apt-get. Update: I initially thought the problem was a resource issues. I erased my entire VPS and started from a fresh Debian image. There is now nothing else running on the system, but even from a clean install my cron daemon is still being killed at random. What else should I check? How do I find out what's killing my crond?

• Agile Database Techniques: Effective Strategies for the Agile Software Developer – book review

  - by DigiMortal

     Agile development expects mind shift and developers are not the only ones who must be agile. Every chain is as strong as it’s weakest link and same goes also for development teams. Agile Database Techniques: Effective Strategies for the Agile Software Developer by Scott W. Ambler is book that calls also data professionals to be part of agile development. Often are DBA-s in situation where they are not part of application development and later they have to survive large set of applications that all use databases different way. Of course, only some of these applications are not problematic when looking what database server has to do to serve them. I have seen many applications that rape database servers because developers have no clue what is going on in database (~3K queries to database per web application request – have you seen something like this? I have…) Agile Database Techniques covers some object and database design technologies and gives suggestions to development teams about topics they need help or assistance by DBA-s. The book is also good reading for DBA-s who usually are not very strong in object technologies. You can take this book as bridge between these two worlds. I think teams that build object applications that use databases should buy this book and try at least one or two projects out with Ambler’s suggestions. Table of contents Foreword by Jon Kern.

• How do you install a USB CD Rom drive?

  - by Matt Allen

  Hello, I recently purchased a USB CD ROM drive, but I don't know how to get it to work with my computer which runs Ubuntu 10.04. http://www.amazon.com/gp/product/B00303H908/ref=oss_product When I issue the lsusb command, it shows up as: Bus 002 Device 016: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter The computer doesn't recognize it automatically. How can I get this drive to show up as an actual drive on my computer? If this particular drive can't handle Linux, can you recommended one which can and provide a link to it so I can purchase it? Thanks!

• PPPD Is Locking the Modem and Not Releasing It

  - by Skid

  Got an issue with PPPD on one of our system, we have a PC that is used to talk to remote sites via a dial up connection, the modem can both connect out to the sites and the sites also dial back in. Currently I'm having an issue where some times a site ether dials in or we dial out, and it connects, but then blocks the modem and throws and error to kern.log.

I've only found two ways to release the modem in this condition, the first is to turn the modem off and on again, the second is to delete the serial lock file, and then SIGKILL pppd. Now I could write into our software to do the latter if the modem is locked, but I would rather stop it from locking in the first place if at all possible. The reason I put this issue in the askubuntu is because we used to use OpenSuse and never had an issue with it, admittedly that was version 11.2 or earlier so its still and old kernel, but I figured I would ask here first anyway. Any suggestions of places to look would be appreciated.

• Desktop login fails, terminal works

  - by Tobias

  I have a freshly setup 12.04 LTS pc system (120 GB SSD, 1 TB HDD, 16 GiB RAM); since a few days, I can't login to the graphical desktop anymore: there is very short flashing shell window which disappears very quickly, and I'm confronted with the login screen again. I believe there is something about modprobe and vbox, but I can't read it fast enough ... I can login to a terminal (Ctrl+Alt+F1). It did not help to chown all contents of my home directory to me:my-group, like suggested here. This is what I could find in /var/log, grepping for the date and time (I inserted linebreaks after <my-hostname>; real time values preserved): auth.log: <date> 22:43:01 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user lightdm <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user tobias by (uid=0) <date> 22:43:08 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user tobias <date> 22:43:09 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user lightdm by (uid=0) <date> 22:43:09 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:10 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:10 <my-hostname> dbus[756]: [system] Rejected send message, 2 matched rules; type="method_call", sender="1:43" (uid=104 pid=1639 comm="/usr/lib/indicator-datetime/indicator-datetime-ser") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.15" (uid=0 pid=1005 comm="/usr/sbin/console-kit-daemon --no-daemon ") kern.log: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present syslog: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present <date> 22:43:01 <my-hostname> ntpdate[1492]: adjust time server 91.189.94.4 offset -0.162831 sec <date> 22:43:08 <my-hostname> acpid: client 969[0:0] has disconnected <date> 22:43:08 <my-hostname> acpid: client connected from 1553[0:0] <date> 22:43:08 <my-hostname> acpid: 1 client rule loaded I have Virtualbox and Truecrypt installed, but I can't think of a reason why they might prevent a graphical login. I'm confused: What is this about requirement "user ingroup nopasswdlogin" not met? I do login using a password, and the password works ok when logging in to a terminal! Can I somehow read the error output, e.g. by delaying it, redirecting it to a file, or having the system prompt me for pressing a key? Has possibly any recent update caused my problem? Should I install the pending updates? How, btw, without access to the graphical UI? I have some working knowledge about the Linux shell, but I'm new to Ubuntu. Any help would be appreciated.

• Intermittent internet connectivity

  - by Rob Oplawar

  UPDATED: I recently built a new computer and set it up to dual-boot Windows 7 and Ubuntu 11.10. In Windows, using the same hardware, my LAN connectivity is solid. In Ubuntu, however, my network interface periodically dies and resets itself; I'll have a solid connection for 30 seconds, and then it will go out for 30 seconds. When I tail the log: tail -f /var/log/kern.log I see "eth0 link up" messages appear periodically, corresponding with the return of connectivity. I posted the original question months ago, and misinterpreted what was going on. With a working Internet connection in Windows, I ignored the problem for some months. See my answer below for the solution (drivers). ORIGINAL POST In Ubuntu, although I maintain a solid connection to my LAN (pinging the router IP address consistently returns a good result), my internet connectivity drops in and out. When I continuously ping 74.125.227.18 (a google.com server), I get responses for a while, then I start getting "Destination Host Unreachable" for a while, then I get responses again. This happens consistently, dropping the connection for about 30 seconds out of every minute or two. Whether I configure my network via the network manager or via /etc/network/interfaces seems to make no difference. I configure with the following settings: address 192.168.1.101 network 192.168.1.0 gateway 192.168.1.99 (my router's IP address) netmask 255.255.255.0 (confirmed as the right netmask for the router) broadcast 192.168.1.255 (also confirmed with the router). ifconfig confirms that these settings are working: eth0 Link encap:Ethernet HWaddr 50:e5:49:40:da:a6 inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::52e5:49ff:fe40:daa6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11557 errors:0 dropped:11557 overruns:0 frame:11557 TX packets:13117 errors:0 dropped:211 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9551488 (9.5 MB) TX bytes:1930952 (1.9 MB) Interrupt:41 Base address:0xa000 I get the same issue when I use automatic DHCP address settings, although I did confirm that there is no other machine on the network with the static IP address I want to use. As I said, the connection to the local network stays solid - I never have any trouble pinging 192.168.1.* - it's internet addresses that I intermittently cannot reach. It's not a DNS issue because pinging known IP addresses directly shows the same behavior. Also, I don't think it's a hardware issue, as I never have any internet connectivity problems on the same machine in Windows. The network hardware is built into the motherboard: Gigabyte Z68XP-UD3P. I managed to bring the OS fully up to date, according to the update manager, but it didn't fix the issue, and with my limited understanding of network architecture I'm at my wit's end. The only clue I can see is that ifconfig is reporting a lot of dropped packets, but I'm not sure what to do about it. UPDATE: It seems my problem is a little more generic than I described; now when I try pinging my router and google simultaneously, they both go unreachable at the same time. Running ifdown eth0 and then ifup eth0 brings it back temporarily; if I just wait it comes back after a couple of minutes. I'll broaden my search through intermittent network connectivity problems.

• Ubuntu suddenly freezes

  - by tapan

  I've a strange problem with my ubuntu 10.04 installation. Whenever i boot into ubuntu the entire system freezes / hangs soon after (~ 2 mins in). This problem exists on my windows 7 installation too. However if i start World of Warcraft or Warcraft on windows it doesnt hang for the duration i'm playing the game. After i stop playing and exit the game my laptop hangs inside 2 mins. Here is when it gets weirder. If i disconnect the charger, the laptop doesn't hang. However when I start it in ubuntu recovery mode and drop to root shell and use the 'startx' command everything works perfectly. I cannot figure out what the problem is. i have an intel core2duo 2.2ghz processor, intel mobile 965 graphics, 2 GB RAM for more details here is the output of cat /proc/cpuinfo : processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4389.80 clflush size : 64 power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4388.96 clflush size : 64 power management: here is the output of cat /proc/meminfo MemTotal: 2052440 kB MemFree: 55924 kB Buffers: 579352 kB Cached: 821752 kB SwapCached: 704 kB Active: 897124 kB Inactive: 1032256 kB Active(anon): 412140 kB Inactive(anon): 264804 kB Active(file): 484984 kB Inactive(file): 767452 kB Unevictable: 0 kB Mlocked: 0 kB HighTotal: 1178440 kB HighFree: 6012 kB LowTotal: 874000 kB LowFree: 49912 kB SwapTotal: 995988 kB SwapFree: 986616 kB Dirty: 8928 kB Writeback: 0 kB AnonPages: 527596 kB Mapped: 76536 kB Slab: 39480 kB SReclaimable: 21100 kB SUnreclaim: 18380 kB PageTables: 5672 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2022208 kB Committed_AS: 1856400 kB VmallocTotal: 122880 kB VmallocUsed: 11928 kB VmallocChunk: 104644 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 892928 kB Also the kern.log doesn't show any errors.

• Why is my cron daemon is being killed every few minutes? OpenVZ?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap). With cron running, free -m reports: total used free shared buffers cached Mem: 1024 465 558 0 0 0 -/+ buffers/cache: 465 558 Swap: 0 0 0 My OpenVZ User Beancounters via cat /proc/user_beancounters: Version: 2.5 uid resource held maxheld barrier limit failcnt 172087: kmemsize 8275718 25561636 51200000 51200000 0 lockedpages 0 968 2048 2048 0 privvmpages 113442 266465 262200 262200 3740757 shmpages 788 4004 128000 128000 0 dummy 0 0 0 0 0 numproc 39 98 600 600 0 physpages 50521 208434 0 9223372036854775807 0 vmguarpages 0 0 512000 512000 0 oomguarpages 50521 208447 512000 512000 0 numtcpsock 7 323 4096 4096 0 numflock 7 64 2048 2048 0 numpty 1 4 32 32 0 numsiginfo 0 23 1024 1024 0 tcpsndbuf 137984 17878480 20480000 20480000 0 tcprcvbuf 114688 6983504 20480000 20480000 0 othersockbuf 162960 1074440 20480000 20480000 0 dgramrcvbuf 0 24208 10240000 10240000 0 numothersock 101 353 2048 2048 0 dcachesize 459171 747444 10240000 10240000 0 numfile 1010 4221 50000 50000 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 39 424 2048 2048 0

• Ubuntu Server 10.04 Heavy Network Traffic causes disconnect

  - by K Vaughan

  I'm currently running a headless Ubuntu 10.04 server. Installed is the LAMP stack, Joomla, Virtualbox, phpvirtualbox, webmin and proFTP.. It resolves the IP address so I can access it remotely (either the apache2 webserver or the FTP) using DDClient. Any packages installed have been installed using apt-get. Webmin, although discouraged in Ubuntu Server, is used mostly to administer the webserver aspect. This issue also appeared when I was using Ubuntu Server 10.10. After periods of heavy network traffic, whether local or remote, the connect drops. I'm talking specifically about the transfer of files via FTP, SCP or Samba (the latter of which I seldom use). There is no response to ping or ssh. I can't FTP to the server nor can I load the website. There are times when the server has been on for a few days and everything runs fine because I haven't accessed it much, if at all (thus not much network traffic). I've gone through a few hardware changes although I don't believe this has cause the issue: this has been happening long before I made any changes. At first I thought it was my ISP-provided router blocking traffic because of some kind of misconfiguration (perhaps assuming it was some kind of DoS attack). I've changed routers and still found no success. I've checked syslog, dmesg and kern.log for warnings but have uncovered none. I've ran memtest via the GRUB2 menu at boot and once it turned up 4 errors. I ran again with individual sticks of RAM in various slots and everything turned up fine. I've looked through the BIOS settings and everything looks fine. I've tried unplugging unnecessary pieces of hardware (other internal hard drives, CD drives, floppy, PCI cards, etc). Any help or tips on how I can even begin to troubleshoot this would be very much appreciated. Please note that i've only started playing with servers as a hobby so my knowledge wouldn't be the most refined. I'm comfortable with command line and have the initiative to know how to look up something I can't do. Unfortunately I can't seem to find any issues like this. Additionally: If a solution can't be found some assistance to write a script that will cause the server to reboot automatically if, after x minutes, it gets no response to pinging somewhere like google. Admittedly that's not the cleanest solution should my internet end up going down but I can't think of what else to do.

• Why does Ubuntu 9.10 hang during boot at "Booting processor 1 APIC 0x1 ip 0x6000"?

  - by BraeburnDev

  I recently installed a new copy of Ubuntu 9.10 (Kernel 2.6.31-14) on to my Hp Pavilion dv6t, so I can setup a Linux development environment. The install went flawlessly and I proceeded with Ubuntu's udate manager's long list of updates (292 in all). I also setup a swap file and activated a Nvidia 185 driver for the Nvidia 260m GPU on the machine. After all this was done I restarted the computer and booted into Ubuntu this time with a newer 2.6.31-19 Kernel which was installed from the update manager. During booth the computer hung at this point: Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013136] Performance Counters: Nehalem/Corei7 events, Intel PMU driver. Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013141] ... version: 3 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013142] ... bit width: 48 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013144] ... generic counters: 4 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013146] ... value mask: 0000ffffffffffff Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013147] ... max period: 000000007fffffff Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013149] ... fixed-purpose counters: 3 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013151] ... counter mask: 000000070000000f Feb 24 14:23:12 braeburn-laptop kernel: [ 0.015539] ACPI: Core revision 20090521 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.052264] Setting APIC routing to flat Feb 24 14:23:12 braeburn-laptop kernel: [ 0.052639] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.152580] CPU0: Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz stepping 05 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.270845] Booting processor 1 APIC 0x1 ip 0x6000 I can post a full kern.log of this boot process if requested. Hopefully this is enough information to go on. I should add that I'm still new to configuring and running a Linux OS although I know enough basic command line usage to do software development. This is my attempt to become more familiar with Linux and manage my own system. I'd like to get some insight on the nature of this system hang, what the problem is and how to resolve it. At this point I can scrap the install if I broke something, but my intuition says this is an issue with the kernel recognizing the correct hardware configuration for my system, or perhaps this is an issue with the APIC drivers managing Nehalem's new power management capabilities? Thanks for looking at this issue and providing feed back.

• Ubuntu 12.04 crash analysis - strange binary data on all open files at the moment of crash

  - by lanbo

  A couple of hours ago we got a system crash on Ubuntu 12.04. We checked all the log files and there is nothing suspicious to blame to. Last stuff that was logged was some dovecot activity. There are no kernel panic messages. Nothing. It is a new server (new hardware) we are testing before production. And because it is new hard, I'm suspicious the problem may be due to some faulty hardware. We already run memtester with no problem detected. I'll be happy to hear from other hardware testing tools (the machine has SSD). Anyway, the thing I wanted to ask you is a different one. The strange thing is on every open file at the moment of the crash we found the next sequence of symbols was written into them: "@^@^@^@^@^@^@...". For example, on the syslog log file we got: Apr 16 15:53:56 odyssey dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<info>, method=PLAIN, rip=46.29.255.73, lip=5.9.58.177 ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^ [these continues for about 1000 chars...] ^@^@^@^@Apr 16 15:55:12 odyssey kernel: imklog 5.8.6, log source = /proc/kmsg started. We got all these symbols in all open files. These include: syslog, mail.log, kern.log, ... But also on some logs that are output by php scripts run in CRONs from user accounts (not root). So, any idea why all open files got these characters written during the crash? This is pretty bad since the crash corrupted many files (we don't even know which other ones may be affected). We are suspicious that all open files (in write mode maybe) at the moment of the crash got all these symbols inserted. Why is that? BTW [in case it helps], the system automatically rebooted after the crash but Apache did not start. There were not traces in /var/apache2/*log why apache did not start. After running a "service apache2 start" it started with no problems. Also, we rebooted the machine manually and Apache also started on reboot. But it did not start after the crash and no errors were reported. Thanks guys!

• rsyslogd not monitoring all files

  So.. I've installed Logstash, and instead of using the logstash shipper (because it needs the JVM and is generally massive), I'm using rsyslogd with the following configuration. # Use traditional timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $IncludeConfig /etc/rsyslog.d/*.conf # Provides kernel logging support (previously done by rklogd) $ModLoad imklog # Provides support for local system logging (e.g. via logger command) $ModLoad imuxsock # Log all kernel messages to the console. # Logging much else clutters up the screen. #kern.* /dev/console # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none;local6.none /var/log/messages # The authpriv file has restricted access. authpriv.* /var/log/secure # Log all the mail messages in one place. mail.* -/var/log/maillog # Log cron stuff cron.* /var/log/cron # Everybody gets emergency messages *.emerg * # Save news errors of level crit and higher in a special file. uucp,news.crit /var/log/spooler # Save boot messages also to boot.log local7.* /var/log/boot.log In /etc/rsyslog.d/logstash.conf there are 28 file monitor blocks using imfile $ModLoad imfile # Load the imfile input module $ModLoad imklog # for reading kernel log messages $ModLoad imuxsock # for reading local syslog messages $InputFileName /var/log/rabbitmq/startup_err $InputFileTag rmq-err: $InputFileStateFile state-rmq-err $InputFileFacility local6 $InputRunFileMonitor .... $InputFileName /var/log/some.other.custom.log $InputFileTag cust-log: $InputFileStateFile state-cust-log $InputFileFacility local6 $InputRunFileMonitor .... *.* @@10.90.0.110:5514 There are 28 InputFileMonitor blocks, each monitoring a different custom application logfile..

How can I fix this so that all the files are monitored?

• Rsyslog is not working properly, it does not log anything

  - by Victor Henriquez

  I'm running a Debian server and a couple of days ago my rsyslog started to behave very weird, the daemon is running but it doesn't seem to do anything. Many people use the system but I'm the only one with (legal) root access. I'm using the default rsyslogd configuration (if you think is relevant I'll attach it, but it's the one that comes with the package). After I rotated all the log files, they have remained empty: # ls -l /var/log/*.log -rw-r--r-- 1 root root 0 Jun 27 00:25 /var/log/alternatives.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/auth.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/daemon.log -rw-r--r-- 1 root root 0 Jun 27 00:25 /var/log/dpkg.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/kern.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/lpr.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/mail.log -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/user.log Any try to force a log writing does not have any effect: # logger hey # ls -l /var/log/messages -rw-r----- 1 root adm 0 Jun 26 13:03 /var/log/messages Lsof shows that rsyslogd does not have any log files opened: # lsof -p 1855 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME rsyslogd 1855 root cwd DIR 202,0 4096 2 / rsyslogd 1855 root rtd DIR 202,0 4096 2 / rsyslogd 1855 root txt REG 202,0 342076 21649 /usr/sbin/rsyslogd rsyslogd 1855 root mem REG 202,0 38556 32153 /lib/i386-linux-gnu/i686/cmov/libnss_nis-2.13.so rsyslogd 1855 root mem REG 202,0 79728 32165 /lib/i386-linux-gnu/i686/cmov/libnsl-2.13.so rsyslogd 1855 root mem REG 202,0 26456 32163 /lib/i386-linux-gnu/i686/cmov/libnss_compat-2.13.so rsyslogd 1855 root mem REG 202,0 297500 1061058 /usr/lib/rsyslog/imuxsock.so rsyslogd 1855 root mem REG 202,0 42628 32170 /lib/i386-linux-gnu/i686/cmov/libnss_files-2.13.so rsyslogd 1855 root mem REG 202,0 22784 1061106 /usr/lib/rsyslog/imklog.so rsyslogd 1855 root mem REG 202,0 1401000 32169 /lib/i386-linux-gnu/i686/cmov/libc-2.13.so rsyslogd 1855 root mem REG 202,0 30684 32175 /lib/i386-linux-gnu/i686/cmov/librt-2.13.so rsyslogd 1855 root mem REG 202,0 9844 32157 /lib/i386-linux-gnu/i686/cmov/libdl-2.13.so rsyslogd 1855 root mem REG 202,0 117009 32154 /lib/i386-linux-gnu/i686/cmov/libpthread-2.13.so rsyslogd 1855 root mem REG 202,0 79980 17746 /usr/lib/libz.so.1.2.3.4 rsyslogd 1855 root mem REG 202,0 18836 1061094 /usr/lib/rsyslog/lmnet.so rsyslogd 1855 root mem REG 202,0 117960 31845 /lib/i386-linux-gnu/ld-2.13.so rsyslogd 1855 root 0u unix 0xebe8e800 0t0 640 /dev/log rsyslogd 1855 root 3u FIFO 0,5 0t0 2474 /dev/xconsole rsyslogd 1855 root 4u unix 0xebe8e400 0t0 645 /var/spool/postfix/dev/log rsyslogd 1855 root 5r REG 0,3 0 4026532176 /proc/kmsg I was so frustrated that even reinstall the rsyslog package, but it still refuses to log anything: # apt-get remove --purge rsyslog # apt-get install rsyslog I thought someone had hacked the system, so run rkhunter, chkrootkit, unhide in an attempt to find hide processes / ports and nmap in a remote host to compare with the ports shown by netstat. And I know this doesn't mean anything, but all looks ok. The system also have an iptables firewall that is very restrictive with incoming / outgoing connections.

• Wireless will not connect

  - by azz0r

  Hello, I have installed Ubuntu 10.10 on the same machine as my windows setup. However, it will not connect to my wireless network. It can see its there, it can attempt to connect, yet it will never connect. It will keep bringing up the password prompt everyso often. I have tried turning my security to WEP, I ended up turning it back to WPA2. It is set to AES (noted a few threads on google about that). Can you assist? I would love to dive into Ubuntu, but without the internet its pointless. --- lshw -C network --- *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 logical name: eth0 version: 02 serial: 00:1d:92:ea:cc:62 capacity: 1GB/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8168 driverversion=8.020.00-NAPI duplex=half latency=0 link=no multicast=yes port=twisted pair resources: irq:29 ioport:e800(size=256) memory:feaff000-feafffff memory:f8ff0000-f8ffffff(prefetchable) memory:feac0000-feadffff(prefetchable) *-network description: Wireless interface physical id: 1 logical name: wlan0 serial: 00:15:af:72:a4:38 capabilities: ethernet physical wireless configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bgn --- iwconfig ---- lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Wuggawoo" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Tx-Power=9 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on --- cat /etc/network/interfaces ---- auto lo iface lo inet loopback logs deamon.log --- Jan 19 04:17:09 ubuntu wpa_supplicant[1289]: Authentication with 94:44:52:0d:22:0d timed out.

• Cannot log in to the desktop on ubuntu 11.10?

  - by Jichao

  The problem is, I could log in under the terminal, i could ifup eth0, i could do anything I want in the terminal, but if I use ctrl+alt+f7 goto the gnome login screen, after I input the correct password, the system just send me back to same login screen again. I have created a new user, but it didn't work. I have change all the files under ~/ to jichao:jichao(which is my username) with chown -hR jichao:jichao /home/jichao, but it didn't work too. I searched the internet, somebody said I should see the logs under /var/log/gdm, but there is not a /var/log/gdm directory in my box.

• Wireless card power management

  - by penner

  I have noticed that when my computer in plugged in, the wireless strength increases. I'm assuming this is to do with power management. Is there a way to disable Wireless Power Management? I have found a few blog posts that show hacks to disable this but what is best practice here? Should there not be an option via the power menu that lets you toggle this?
