  • server will not reply (syn -ack)

    - by Brent
    I like to use the following commands to manage 'TIME_WAIT', in the hope to free up resources. echo 20 > /proc/sys/net/ipv4/tcp_fin_timeout sysctl -w net.ipv4.tcp_tw_reuse=1 sysctl -w net.ipv4.tcp_tw_recycle=1 I found something interesting while doing a tcpdump. Sometimes if a client makes a connection (syn), the server will not reply (syn -ack). My question is, could it be because of the top three commands.

  • Install Windows 8 from recovery disk on VirtualBox [on hold]

    - by user1032531
    About 6 months ago, I bought a desktop HP PC with Windows 8 from Costco. I made a recovery disk (actually, took 4 DVDs) of the operating system and copied down the product key. I then did a fresh Cento6 install on the machine. I know wish to operate Windows (8 I guess, but I would rather have 7) on a VirtualBox on the Centos box. Is this possible? Any recommendations where to start? Can I do so without re-installing all the HP baggage?

  • Cannot connect to postgres installed on Ubuntu

    - by Assaf
    I installed the Bitnami Django stack which included PostgreSQL 8.4. When I run psql -U postgres I get the following error: psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? PG is definitely running and the pg_hba.conf file looks like this: # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all md5 # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5 What gives?

  • cgconfig.conf : setting root control group parameters

    - by delerious010
    I've got cpu, cpuacct and memory cgroups configured via /etc/cgconfig.conf ( cgconfig-bin on Lucid ). I can add new control groups, and assign processes to them however there does not seem to be a facility for changing the paramters of the root level memory cgroup ( the actual mount point ). How would one best set such parameters in a clean manner withoput c For example, I've the memory cgroup mounted to /var/run/cgroup/memory. I'd like to have /var/run/cgroup/memory/memory.use_hierarchy set to 1 on boot.

  • How do I align the bottom edges of two monitors with xrandr?

    - by denaje
    I have two outputs that I'd like to use on my laptop: LVDS1 - 1366x768 HDMI1 - 1920x1080 I set my monitors up like so: xrandr --output LVDS1 --auto --output HDMI1 --auto --right-of LVDS1 This is all well and good, but my laptop sits considerably lower than my external monitor, and with the top edges of the screens being aligned, it makes the jump from one screen to the other rather unintuitive. Is there a way I can align the bottom edges instead? I thought I could use the --pos flag to do this, but I have tried and not seen any difference (perhaps I do not know how to use it properly). EDIT: Solved. Thanks to tink's link, I deconstructed the Python script and discovered the way to do this is as follows: xrandr --output LVDS1 --pos 0x312 # 312 = 1280 - 768 xrandr --output HDMI1 --pos 1366x0 Not sure I understand exactly what the --pos flags are doing here, but it at least works!

  • Is it possible to format ps RSS (memory) output to be more human friendly?

    - by metasoarous
    Executing ps ux returns a nice list of process information, easy to grep through or watch. However, there doesn't seem to be much flexibility in the memory usage output; the RSS (resident set size) is printed in kB, which for large processes is hard to read (especially at a glance), and %MEM gives 100 × RSS / system_memory. The du utility has a lovely -h flag which prints space in a more user friendly fashion. I have not been able to find anything equivalent for ps. Is there a special formatting trick that can accomplish this?

  • mdadm raid5 recover double disk failure - with a twist (drive order)

    - by Peter Bos
    Let me acknowledge first off that I have made mistakes, and that I have a backup for most but not all of the data on this RAID. I still have hope of recovering the rest of the data. I don't have the kind of money to take the drives to a recovery expert company. Mistake #0, not having a 100% backup. I know. I have a mdadm RAID5 system of 4x3TB. Drives /dev/sd[b-e], all with one partition /dev/sd[b-e]1. I'm aware that RAID5 on very large drives is risky, yet I did it anyway. Recent events The RAID become degraded after a two drive failure. One drive [/dev/sdc] is really gone, the other [/dev/sde] came back up after a power cycle, but was not automatically re-added to the RAID. So I was left with a 4 device RAID with only 2 active drives [/dev/sdb and /dev/sdd]. Mistake #1, not using dd copies of the drives for restoring the RAID. I did not have the drives or the time. Mistake #2, not making a backup of the superblock and mdadm -E of the remaining drives. Recovery attempt I reassembled the RAID in degraded mode with mdadm --assemble --force /dev/md0, using /dev/sd[bde]1. I could then access my data. I replaced /dev/sdc with a spare; empty; identical drive. I removed the old /dev/sdc1 from the RAID mdadm --fail /dev/md0 /dev/sdc1 Mistake #3, not doing this before replacing the drive I then partitioned the new /dev/sdc and added it to the RAID. mdadm --add /dev/md0 /dev/sdc1 It then began to restore the RAID. ETA 300 mins. I followed the process via /proc/mdstat to 2% and then went to do other stuff. Checking the result Several hours (but less then 300 mins) later, I checked the process. It had stopped due to a read error on /dev/sde1. Here is where the trouble really starts I then removed /dev/sde1 from the RAID and re-added it. I can't remember why I did this; it was late. mdadm --manage /dev/md0 --remove /dev/sde1 mdadm --manage /dev/md0 --add /dev/sde1 However, /dev/sde1 was now marked as spare. So I decided to recreate the whole array using --assume-clean using what I thought was the right order, and with /dev/sdc1 missing. mdadm --create /dev/md0 --assume-clean -l5 -n4 /dev/sdb1 missing /dev/sdd1 /dev/sde1 That worked, but the filesystem was not recognized while trying to mount. (It should have been EXT4). Device order I then checked a recent backup I had of /proc/mdstat, and I found the drive order. md0 : active raid5 sdb1[0] sde1[4] sdd1[2] sdc1[1] 8790402048 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/4] [UUUU] I then remembered this RAID had suffered a drive loss about a year ago, and recovered from it by replacing the faulty drive with a spare one. That may have scrambled the device order a bit...so there was no drive [3] but only [0],[1],[2], and [4]. I tried to find the drive order with the Permute_array script: https://raid.wiki.kernel.org/index.php/Permute_array.pl but that did not find the right order. Questions I now have two main questions: I screwed up all the superblocks on the drives, but only gave: mdadm --create --assume-clean commands (so I should not have overwritten the data itself on /dev/sd[bde]1. Am I right that in theory the RAID can be restored [assuming for a moment that /dev/sde1 is ok] if I just find the right device order? Is it important that /dev/sde1 be given the device number [4] in the RAID? When I create it with mdadm --create /dev/md0 --assume-clean -l5 -n4 \ /dev/sdb1 missing /dev/sdd1 /dev/sde1 it is assigned the number [3]. I wonder if that is relevant to the calculation of the parity blocks. If it turns out to be important, how can I recreate the array with /dev/sdb1[0] missing[1] /dev/sdd1[2] /dev/sde1[4]? If I could get that to work I could start it in degraded mode and add the new drive /dev/sdc1 and let it resync again. It's OK if you would like to point out to me that this may not have been the best course of action, but you'll find that I realized this. It would be great if anyone has any suggestions.

  • Look strange on gvim after applying Source Sans Pro font

    - by abcdabcd987
    I downloaded the Source Sans Pro font and install on my Fedora17(Xfce). I did mkfontscale, mkfontdir, fc-cache -fv, and after fc-list, could see it on the list. Then I changed guifont in gvim to Source\ Sans\ Pro\ 10, but it looks quite strange. And then I changed it to DejaVu\ Sans\ Mono\ 10, it looks nothing strange. So, why would this happend? And how to solve it? Thanks! Source Sans Pro DejaVu Sans Mono

  • Increase text size in Ubuntu 10.04 due to having large resolution/monitors

    - by Sridhar Ratnakumar
    I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe? I am using Ubuntu 10.04 (Lucid Lynx)

  • Which mail clients can give reminders about unresponded emails?

    - by ulidtko
    In my daily e-mail often happens the following scenario: I send somebody an email which describes some problem and requests an action from the recipient. Typically, I wish to ensure that this action was taken, or at least somehow resolved; when this happens, the email recipient should notify me with a response email about what was done, and what was not and why. But, sometimes emails don't get read by the recipient, or he forgets to reply to me. At the same time, I cannot constantly keep in memory the list of all emails for which I was waiting an answer and still didn't receive it. So I wonder, is there in any email client such a feature which would allow me to somehow mark specific outgoing emails as "demanding reply"? The mail client could in this case notify me if any "demanding reply" emails still aren't replied for a long time.

  • Samba PDC share slow with LDAP backend

    - by hmart
    The scenario I have a SUSE SLES 11.1 SP1 machine as Samba master PDC with LDAP backend. In one share there are Database files for a Client-Server application. I log XP and Windows 7 machines to the local domain (example.local), the login is a little slow but works. In the client computers have an executable which opens, reads and writes the database files from the server share. The Problem When running Samba with LDAP password backend the client application runs VERY SLOW with a maximum transfer rate of 2500 MBit per second. If disable LDAP the client app speed increases 20x, with transfer rate of 50Mbit/sec and running smoothly. I'm doing test with just two users and two machines, so concurrency, or LDAP size shouldn't be the problem here. The suspect LDAP, Smb.conf [global] section configuration. The Question What can I do? I've googled a lot, but still have no answer. Slow smb.conf WITH LDAP [global] workgroup = zmartsoft.local passdb backend = ldapsam:ldap://127.0.0.1 printing = cups printcap name = cups printcap cache time = 750 cups options = raw map to guest = Bad User logon path = \\%L\profiles\.msprofile logon home = \\%L\%U\.9xprofile logon drive = P: usershare allow guests = Yes add machine script = /usr/sbin/useradd -c Machine -d /var/lib/nobody -s /bin/false %m$ domain logons = Yes domain master = Yes local master = Yes netbios name = server os level = 65 preferred master = Yes security = user wins support = Yes idmap backend = ldap:ldap://127.0.0.1 ldap admin dn = cn=Administrator,dc=zmartsoft,dc=local ldap group suffix = ou=Groups ldap idmap suffix = ou=Idmap ldap machine suffix = ou=Machines ldap passwd sync = Yes ldap ssl = Off ldap suffix = dc=zmartsoft,dc=local ldap user suffix = ou=Users

  • Use inotifywait and lftp to synchronize servers

    - by KBoek
    I have two servers: Server A (CentOS), where people can upload files to (upload root is /files) Server B (Win 2008), with FileZilla FTP Server (FTP root is C:\content) I want that whenever a file is uploaded to Server A, to any subfolder under /files, the file is automatically copied to the exact same subfolder on Server B. Thus, if a user uploads "flowers.jpg" to /files/photos/12345/ then the file must be copied over FTP to C:\content\photos\12345 So far I have this bash script, it does copy the files to server B, but all files are placed in C:\content, and not in the corresponding subfolders. Who can help me find the correct syntax? #!/bin/bash cd /files inotifywait -q -r -m -e close_write,moved_to . --format %w%f | while read FILE; do lftp -e "put $FILE; exit" -u user,password -p 2121 ftp.server-a.com done

  • Simultanious process mysteriously ending

    - by Matt
    I'm trying to run a large air quality model, written in FORTRAN, setup with bash scripts, and run in a work queue (slurm.) The first part of the modeling is to run an "entry" model, this runs with MPI in the work queue but only on one process. At one point in the logs, there's a mysterious FORTRAN STOP, and then later the model fails because something wasn't set up properly. This FORTRAN STOP isn't from the main process, which continues running. This is a huge model, but as far as I know there should not be any other processes running at the same time. It consistently fails at the exact same spot. (I can move it by adding debug, but the debug is in the main process) How can I determine what this process is? I've tried added a call to strace -feprocess $SHELL in the run script, but I'm new to this, so if it has offered any info, I haven't been able to use it yet. The is no trace output around the FORTRAN STOP. The whole process occurs so fast that I can't seem to observe it by using ps. Is there a way I can somehow monitor all the processes being initiated from the time the work queue starts? Or some other way I can figure out what is failing? This is running on CentOS 6.4, with Slurm, compiled with PGI 13.

  • Serve up PC hard drive as USB mass storage

    - by sheepsimulator
    Is there a software package available that can serve up a hard-drive internal to a PC and make it available over USB to other USB Master nodes as mass storage? Ex: take your C: or /dev/hda drive on a PC (let's call the computer PC-A), and run a driver program which makes your C: or /dev/hda drive available to external devices as USB mass storage. When you'd hook up another PC (PC-B) to PC-A via USB, it would detect a USB mass storage device, which is C: or /dev/hda on PC-A. Is this even possible? EDIT: I know that there are other ways of making data on a drive available between two different computers (eg. putting PC-A's hdd in a USB-drive-enclosure, or having PC-A make the hdd available via a network share). But I'd like to know if the method that I describe above is even technically possible.

  • Connect devices plugged into Raspberry Pi ethernet to WiFi network

    - by Tom
    I'm just starting out on a mission to learn more about networking and I've followed a tutorial (http://raspberrypihq.com/how-to-turn-a-raspberry-pi-into-a-wifi-router/) to turn my Raspberry Pi into a wifi router. That worked really well so I modified it slightly so that I can use a tethered iphone for the internet connection - I just switched all "eth0" references to "eth1" (the iphone interface) and added a script to set everything up when the phone is plugged in. This setup has freed up the Pi's ethernet port so I'd like to try and take this a step further and allow devices plugged into it to connect to the network. If possible, I'd like to try adding a switch so I can connect multiple devices. I've tried fiddling around with nat & iptables with no luck so my question is, how can I connect devices on eth0 to my wlan network?

  • Apache strace to hunt down a memory leak

    - by Zipp
    We have a server with a memory issue: the server keeps allocating itself memory and doesn't release it. We're running Apache.

  • Virtualized Screen Resolution

    - by Jim R
    I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04. The problem is that I would like to use a larger size display that is configured by default. Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080. This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation. The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file. I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily. Is what I want to do possible? If so, how do I accomplish it?

  • rsync - Exclude files that are over a certain size?

    - by Rory
    I am doing a backup of my desktop to a remote machine. I'm basically doing rsync -a ~ example.com:backup/ However there are loads of large files, e.g. wikipedia dumps etc. Most of the files I care a lot about a small, such as firefox cookie files, or .bashrc. Is there some invocation to rsync that will exclude files that are over a certain size? That way I could copy all files that are less than 10MB first, then do all files. That way I can do a fast backup of the most important files, then a longer backup of everything else.
