  • Why do most songs in my media collection play twice? - Corrupt media?

    - by Dean
    Problem: Whether I'm playing the media with Rhythmbox on Ubuntu, Winamp on Windows, or my Nokia N95's media player, most of my audio files (OK, maybe only 40%) play twice. Info: I have a 500GB external 2.5" WD HDD, with a 150GB primary FAT32 partition labeled MUSIC. Inside this, I have about 500 folders containing about 10,000 MP3/WMA/M4A/WAV files. I manage the drive using Ubuntu 9.10, and frequently copy data to/from it using RSYNC, or on windows, TotalCopy. The visual output is different in each media player, but it behaves as if the 1 MP3 has the same song on it twice, and as soon as it ends it begins again. Winamp shows that the song goes for 2x as long as it should, The N95's media player shows the progress bar off the right-hand-side of the screen when it begins playing (then jumps back to the left, then continues along...). Rhythmbox doesn't show me how long the song is, nor does the progress bar move along the screen. Plea: It seams to me somewhere along the lines my collection has become corrupt... but where? And how? and please someone tell me I can fix it!! TIA, Dean.

  • How do I increase the buffer size for domain sockets in OS X 10.6

    - by Chas. Owens
    In Linux I have no problem dumping tons of data into a domain socket, but the same code on OS X 10.6.2 blows up after about 65 records. The socket reader code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; unlink "foo"; my $sock = IO::Socket::UNIX->new ( Local => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; while (<$sock>) { chomp; print "[$_]\n"; } And the client code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; my $sock = IO::Socket::UNIX->new ( Peer => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; for my $i (1 .. 1_000_000) { print $sock "$i\n" or die $!; } close $sock; The error message I get is No buffer space available at write.pl line 15.. It seems fairly obvious that there is a difference in the buffer size between Linux and OS X, but I don't know how to set it OS X (or what the possible negative side effects might be).

  • How to make ssh connection between servers using public-key authentication

    - by Rafael
    I am setting up a continuos integration(CI) server and a test web server. I would like that CI server would access web server with public key authentication. In the web server I have created an user and generated the keys sudo useradd -d /var/www/user -m user sudo passwd user sudo su user ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/var/www/user/.ssh/id_rsa): Created directory '/var/www/user/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /var/www/user/.ssh/id_rsa. Your public key has been saved in /var/www/user/.ssh/id_rsa.pub. However othe side, CI server copies the key to the host but still asks password ssh-copy-id -i ~/.ssh/id_rsa.pub user@webserver-address user@webserver-address's password: Now try logging into the machine, with "ssh 'user@webserver-address'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. I checked on the web server and the CI server public key has been copied to web server authorized_keys but when I connect, It asks password. ssh 'user@webserver-address' user@webserver-address's password: If I try use root user rather than my created user (both users are with copied public keys). It connects with the public key ssh 'root@webserver-address' Welcome to Ubuntu 11.04 (GNU/Linux 2.6.18-274.7.1.el5.028stab095.1 x86_64) * Documentation: https://help.ubuntu.com/ Last login: Wed Apr 11 10:21:13 2012 from ******* root@webserver-address:~#

  • Identify differences between MP3 files

    - by Thingomy
    I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.

  • Ubuntu second static IP, ifconfig, /etc/network/interfaces

    - by Schmoove
    I would like to add a second static IP to my local Ubuntu 11.10 desktop machine and have it automatically available after rebooting. So far I am successfully using ifconfig to to temporarily set up an alias for my primary network interface: # ifconfig eth1:0 192.168.178.3 up # ifconfig eth1 Link encap:Ethernet HWaddr c8:60:00:ef:a3:d9 inet addr:192.168.178.2 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::ca60:ff:feef:a3d9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:61929 errors:0 dropped:0 overruns:0 frame:0 TX packets:64034 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:45330863 (45.3 MB) TX bytes:28175192 (28.1 MB) Interrupt:42 Base address:0x4000 eth1:0 Link encap:Ethernet HWaddr c8:60:00:ef:a3:d9 inet addr:192.168.178.3 Bcast:192.168.178.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:42 Base address:0x4000 However, when I add the following to /etc/network/interfaces, the alias is not up and running as expected after a reboot: # vi /etc/network/interfaces auto eth1:0 iface eth1:0 inet static address 192.168.178.3 netmask 255.255.255.0 I would like to know what to configure to get this to work. As a side note, I am running gnome shell.

  • DNS issue for internal website routing internet connection from remote location

    - by Michael Paul
    I have an issue that I could use some help with. Our company has a main location and a remote location. Previously, the remote location was connected to the main location through an internet connection VPN tunnel. The connection was pitifully slow at 1.5Mbps, so we upgraded it with a 75Mbps direct link. That meant the remote location lost it's internet access, so we routed their access through the main office internet connection. Everything works perfect except for one thing. The website we host is not accessible from the remote location unless the IP address is used. If I do NSLOOKUP on our website address from a machine connected to the main location network, it resolves correctly to the inside IP address. However, if I do the same from a remote location machine, it resolves to the website's outside IP address. Our internal DNS server(s) have a pointer and CNAME records set up, and everything was working perfectly before the connection was upgraded. In addition, the remote location has a domain controller, DNS server and DHCP server to service these requests at the remote location and prevent these requests from getting routed back and forth over the link. So I think was it happening is that for some reason the DNS server at the remote location is not resolving our website name correctly and passing the requests on to the routers, which then push the request out to the internet DNS system. That resolves the name to our external IP. This is purely a DNS issue, everything else works just fine. I am just stumped on this one. Any ideas on how to fix this? Edit: I forgot to mention that at the remote side of the link is a Cisco ASA-5505 and at the main office there is a Cisco ASA-5510. The link is connected between these 2 devices and the routing is handled in the 5510. Thanks, Michael

  • How can I find files added to the system within X minutes of a specific time?

    - by Jack W-H
    I have done a fresh install of Mac OS X Mountain Lion today on a new MacBook. Because this was a new install, when I finally got round to configuring some of my own developer things, I was surprised to find some app had installed a binary into /usr/local/bin - a single binary called galileod. Interestingly, I can't find anything online about galileod. I had only installed the bare minimum of software at this point. Looking in the file columns I can see Date Modified was 9th November 2012, but Date Added to the system was today at 17:01. It's now 10:20PM and I can't remember which software I was installing at that point. So how do I find out which other files were installed to the system within, say, 5 minutes either side of 17:01? EDIT: I found out what galileod was by running galileod --help - it is a binary used with Fitbit to communicate with the USB dongle. So that's the mystery solved - but it would still be interesting to know how to find files added within X minutes of a timeframe for future reference.

  • Why do messenger keeps coming up when I adjust screen brightness?

    - by Asaf R
    My Dell Studio XPS 13 has a brightness up & down buttons (Fn + up arrow / down arrow), as do most laptops have. It's running Windows 7 64bit and I've installed Windows Live Messenger (build 14 and something) on it. When I hit Fn + down arrow, to reduce screen brightness, the Messenger window pops up. That's true whether it has been running in background (system tray / minimized) before or not. Note, to make messenger hide itself to the system tray, I've set it to Vista Compatibility mode. I don't think that has anything to do with it though, since if I shut compatibility mode off, the problem persists. There's a thread on the matter here, but with no solution. Thanks, Asaf SOLUTION: Stop Intellitype when using internal keyboard. See detailed howto here. EDIT: Some new findings on the matter - If I exit messenger entirely and restart (or simply stop) the service "Windows Live ID Sign-in Assistant" the problem is solved until I run messenger again. It persists even after entirely closing messenger, until I restart the said service. EDIT2: The above service "Windows Live ID Sign-in Assistant" actual name is wlidsvc. There's no shortcut defined for messenger, nor is there any other hot key in its preferences. EDIT3: I'm not sure if it's relates, but some of the Fn keys are not working - Fn + F1 doesn't put the machine to sleep, Fn + F3 doesn't show battery status. EDIT4: Problem probably relates to conflict with IntelliType Pro. See my answer below. Said conflict also causes Undo command when disabling Wireless (Wireless touch button), and other side effects for various keys.

  • Asterisk terminating outbound call when picked up, sends 'BYE' message

    - by vo
    I'm running Asterisk 1.6.1.10 / FreePBX 2.5.2.2 and I've got an outbound trunk setup. Everything use to work fine until recently (perhaps due to upgrade to FC12 or other things I'm not sure). Anyway the setup does not appear to have issues registering and setting up the call, RTP packets go both ways and you can hear the ringing from the other side. However it appears that when the call is picked up or thereabouts, the incoming RTP packets cease. Upon closer inspection with Wireshark, there are these particular packets that seem to be the cause: trunk->asterisk SIP/SD Status: 200 OK, with session description asterisk->trunk SIP Request: ACK sip:<phone>@trunk:6889 asterisk->trunk SIP Request: BYE sip:<phone>@trunk:6889 [..about a dozzen RTP packets in/outbound..] trunk->asterisk SIP Status: 200 OK, CSeq: 104 Bye [..outbound RTP continues, phone is silent..] Then the inbound RTP packets cease, however the asterisk logs dont show any activity at this point. The last entry reads 'SIP/ is answered SIP/'. Then when you hangup the extension, you get asterisk->trunk SIP Request: BYE sip:<phone>@trunk:6889 trunk->asterisk SIP Status: 481 Call Leg/Transaction does not exist My trunk peer settings in FreePBX are: username=<user> fromuser=<user> canreinvite=no type=friend secret=<pass> qualify=no [qualify yes produces 401/forbidden messages] nat=yes insecure=very host=<sip trunk gateway> fromdomain=<sip trunk gateway> disallow=all context=from-pstn allow=ulaw dtmfmode=inband Under sip_general_custom.conf i have stunaddr=stun.xten.com externrefresh=120 localnet=192.168.1.1/255.255.255.0 nat=yes Whats causing Asterisk to prematurely end the call and still think the call is in progress? I have no idea where to look next.

  • What does a connection timeout indicate when performing an NFS mount?

    - by DeeDee
    We have a shiny new QNAP NAS (TS-879U-RP), and I'm trying to mount it to our big ol' RHEL server in the same manner as our other two QNAP NAS devices. The IT department won't give me the root privileges to the NAS, so I can't SSH in (I know, I know). The first thing I did was to, via the QNAP web admin interface, create a network share named "Runs." I then added the IP of the RHEL server to the permissions list: On the RHEL server, I then added the following line to /etc/fstab: [IP of NAS]:/Runs /mnt/gsrnas3 nfs defaults 0 0 Aside from the IP and the specific mount directory name, this is how I mounted the other two NAS devices. I then created the gsrnas3 directory under /mnt/, and then ran `mount /mnt/gsrnas3' I got the following error: mount.nfs: Connection timed out My first thought is that it's a ports issue, but I don't have enough specific experience with this issue to know for sure. I have two other NAS devices by the same manufacturer already mounted to this RHEL server, so that leads me to believe the configuration issue is on the NAS side of things. I can ping the NAS device successfully from the RHEL server. Not being able to SSH into said NAS is a huge hassle, though. Any ideas?

  • Ubuntu server or Debian server (to run C++ apps developed on Ubuntu)

    - by skyeagle
    I have written a number of C++ server side daemons for my website, using my Ubuntu 9.10 dev machine. The C++ apps I mentioned above are "GUI-less" daemons (and libraries used by the daemons). I am now about to host my website and need to decide whether to go with Debian server or Ubuntu server. In a nutshell, here is the situation: I developed on Ubuntu desktop because I preferred the more friendly GUI I would like to deploy on Debian Server because of the (perceived?) robustness of the Debian server over Ubuntu server (I may be totally wrong here - and in fact, this is really what this question is all about) If Debian server is indeed more robust than Ubuntu server, then I have no choice but to go with Debian server - BUT, will my Ubuntu developed C++ apps run on the server? (or do I need to recompile them on the server? (I'd HATE to have to do this, because I want to keep the server machine clean and light - no GUI, no dev tools etc). This last question is really about binary compatability between Ubuntu and Debian. I want the server to be robust, secure and stable, and simply act as a server (i.e. LAMP and very little else - no GUI etc). Given that requirement, and the fact that I need to run my C++ apps (developed on Ubuntu 9.10), I need advice on which OS to choose for the server. Ideally, any advice will be backed with a reason. I am particularly interested in hearing from people who have been in an identical situation, or done something similar.

  • windows 7: Event 55 The file system structure on the disk is corrupt and unusable

    - by Radio
    Here is a real bad one! Windows 7 RTM with SP1 installed [Version 6.1.7601]. Recently tried to delete some folder on my hard drive and Windows prompted "Error 0x80070570: The file or directory is corrupted and unreadable", and at the same time placed an Event 55 describing "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on \Device\HarddiskVolume2." Ran chkdsk, first with /f option, then with /r option. Result in both cases was: no errors found, 0 bad sectors. No problems chkdsk found at all! Went through StackExchange, Google and spent over 6 hours on this. Still cannot figure out the problem. Re-installing/Re-Formatting is not an option! What did I try: Hotfix - Windows6.1-KB982927-x64.msu - gave me an error about incompatibility with my computer, however it totally matches my system. CRC of hotfix was ok. Windows Repair Console found startup errors and fixed those, but this didn't help an issue, even by running chkdsk c: /R from it. http://support.microsoft.com/kb/246026 does not promise anything good. sfc /scannow does not help too. Replaced hard drive by cloning an old one using True Image, repeated all steps above. At the same time, some minor glitches started to appear in my Windows, like side panel and notification area settings are getting reset. Goal is to delete the folder and get rid of Event 55. Sounds like NTFS bug. Please help. This is completely ridiculous.

  • File in use when it's really not

    - by C-dizzle
    I am running Windows 7 Professional 32 bit on a Server 2008 network. I am getting a weird issue with an excel document where I open it up one morning, update it, save and close, the next morning I come in, open it up and it says "This file is in use and locked by csmith" which "csmith" is me! So I click on the cancel button, open it up again and it comes up fine. I can edit, save and close with no problem. But then have the same issue the next morning. Another weird thing is that we have a calendar shared in "Public Folders" under Outlook that seems to be having the same issue, which happens to be a calendar made in Excel. Exchange 2010 is installed on the server and the clients are using Exchange 2007. In the instance with the calendar, it will show conflicting edits have been made and you must keep one item or all items. And it shows an edit date of 4/24/2012 and 6/1/2012. But, there were NO edits done on 6/1, just tried opening it. This problem does not occur under my profile, but 2 others. These machines are ALSO running Windows 7 Professional 32 bit. We have a mix of Windows 7 and Windows XP machines on our network if that is any help. These issues did not start happening until we migrated from a server running Server 2003 and Exchange 2000, which the new server is running Server 2008 and Exchange 2010 as stated above. Is there something on the server side that is configured wrong?

  • Access router set up as a bridge behind another router

    - by Alari Truuts
    I have a problem my ISP is refusing to help me with, even though they put up the whole system. Specifications: There's a Thomson TG784 router through which the internet comes in to the building, Behind that (for some reason) is a Juniper NetScreen 5XT - 105 Firewall/Router? which leads to an AMX nxa-enet24 switch that carries the connections all over the building and a series of Apple AirPorts for wifi. Problem: The first router (Thomson) is required for ipTV (by Elion). The tv or ipTV box has to be connected straight to the Thomson router. My service provider cannot see the Thomson router from their side, but see the Juniper, so we might think the Thomson has been configured as a bridge. I need a way to access the Thomson router and see it's configurations, because currently, when connecting a Samsung tv to that router (with elion app for ipTV viewing) or even a computer, it cannot access the internet and even if it could, it would update the Thomson router software, losing it's configurations which I need to preserve. I'm unable to find out the Thomson routers ip address to connect to it, and when directly conencting with a cat5 cable, it doesn't give me an ip address. Hope someone can show me the correct direction for solving my issue. Thank you all for reading, and I appreciate any help, Alari Truuts

  • SELinux blocking Samba directory listing

    - by Sean M
    I am running Samba on a CentOS server, and I am experiencing a problem where it allows me to connect to the server and see a share, but shows the share as an empty directory. I find this behavior strange. Here is the stanza in my smb.conf for the given share: [seanm] path = /home/seanm writeable = yes valid users = seanm, root read only = No Here's what I see on the server side: [seanm@server ~]$ ls -l -rw-r--r-- 1 seanm seanm 40 Jan 4 13:45 pangram.txt And yet: [seanm@client ~]$ smbclient //server/seanm -U seanm -W WORKGROUP Enter seanm's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.33-3.29.el5_5.1] smb: \> ls . D 0 Fri Jan 7 10:08:55 2011 .. D 0 Fri Jan 7 07:58:31 2011 58994 blocks of size 262144. 50356 blocks available This behavior is present on both a Windows client and a Linux client system. The behavior is present with the firewall on and with the firewall off, so it's not that. Neither /var/log/messages nor /var/log/secure have any complaints about Samba. I doubt that SELinux is a problem: just in case, here are the relevant settings. [root@server ~]# getsebool -a | grep samba samba_domain_controller --> off samba_enable_home_dirs --> on samba_export_all_ro --> off samba_export_all_rw --> off samba_share_fusefs --> off samba_share_nfs --> off use_samba_home_dirs --> on virt_use_samba --> off What am I doing wrong here, and what can I do to fix it? Edit: SELinux probably is the problem, judging by the fact that the issue goes away when I set SELinux to "permissive" or issue setsebool -P samba_export_all_rw on - both of which are unacceptable for production environments. What the heck kind of context does a directory need to have on it for Samba users to actually get files from it? I consider rolling your own rules and/or context to be deeply sub-optimal.

  • Campus VLAN Segmentation - By OS?

    - by Moduspwnens
    We've been thinking through re-arranging our network and VLAN configuration. Here's the situation. We already have our servers, VoIP phones, and printers on their own VLANs, but our problem lies with end user devices. There are just too many to lump on the same VLAN without being hammered with broadcasts! Our current segmentation strategy has them split into VLANs like this: Student iPads Staff iPads Student Macbooks Staff Macbooks Gaming devices Staff (Other) Student (Other) *Note that our network has many more iPads and MacBooks than most. Since the primary reason we're splitting them is just to put them in smaller groups, this has been working for us (for the most part). However, this required our staff to maintain access control lists (MAC addresses) of all devices belonging in these groups. It also has the unfortunate side effect of illogically grouping broadcast traffic. For example, using this setup, students on opposite ends of campus using iPads will share broadcasts, but two devices belonging to the same user (in the same room) will likely be on completely separate VLANs. I feel like there must be a better way of doing this. I've done a lot of research and I'm having trouble finding instances of this kind of segmentation being recommended. The feedback on the most relevant SO question seems to point toward VLAN segmentation by building/physical location. I feel like that makes sense because logically, at least among miscellaneous end users, broadcasts will typically be intended for nearby devices. Are there other campuses/large-scale networks out there segmenting VLANs based on end-system OS? Is this a typical configuration? Would VLAN segmentation based on physical location (or some other criteria) be more effective? EDIT: I've been told that we will soon be able to dynamically determine device OS without maintaining access lists, although I'm not sure how much that affects the answers to the questions.

  • Using Toshiba 22EL833 as PC display through HDMI input

    - by Oleg V. Volkov
    I had another Toshiba TV - 19SL738 - connected to this same PC and video card (GTX 8800) through DVI<-HDMI (DVI on PC side, HDMI on TV) before, that was working perfectly at it's native resolution 1360x768. Some time ago I had to change to 22EL833 and immediately faced problem with Windows 7 control panel and NVIDIA control panel both reporting native resolution for new TV as 1080i, 1920x1280, despite TV documentation saying that it have same 1360x768 as previous one. Practical tests confirmed that true native resolution is indeed 1360x768, because plugging in through DVI<-VGA and setting custom resolution through NVIDIA panel shown clear colors and crisp image, while setting anything different with either DVI<-VGA or DVI<-HDMI produced horribly distorted or squished images, with almost unreadable slim lines (as in letters, for example). Now, my problem is that there's no drivers for this TV and I'm unable to get good image while connecting it through DVI<-HDMI directly. The best I've achieved is editing EDID/driver manually, to persuade system that native resolution should be 1360x768, and while image became mostly clear, colors turned to some strange washed out effect, with pools of pure yellow, cyan and magenta there and there filling place of other colors. Gradients also became noticeably stripped as well. Somehow it looks like dithering gone bad and makes me suspect that image is still down/upscaled several times internally somewhere along the line. How can I connect this TV to DVI output of my video card to get best possible clear image, correct colors and correct native resolution?

  • Saving a file in a CSV type in Excel always removes the BOM

    - by rickp
    I've been trying to find a reasonable solution/explanation (unsuccessfully) to find out why Excel defaults to removing the BOM when saving a file to the CSV type. Please forgive me if you find this a duplicate of this question. This handles reading CSV files with non-ASCII encoding, but it doesn't cover saving the file back out (which is where the biggest issue lies). Here is my current situation (which I'm going to gather is common among localized software dealing with Unicode characters and a CSV format): We export data to a CSV format using UTF-16LE, ensuring the BOM is set (0xFFFE). We validate after the file is generated with a Hex editor to ensure it was set correctly. Open the file in Excel (for this example we're exporting Japanese characters) and witness that Excel handles loading the file with the correct encoding. Attempts to save this file will prompt you with a warning message indicating that the file may contain features that may not be compatible with Unicode encoding, but asks if you'd like to save anyway. If you select the Save As dialog, it will immediately ask you to save the file as "Unicode Text" rather than CSV. If you select the "CSV" extension and save the file it removes the BOM (obviously along with all the Japanese characters). Why would this happen? Is there a solution to this problem, or is this a known 'bug'/limitation of Excel? Additionally (as a side issue) it appears that Excel, when loading UTF-16LE encoded CSV files, only uses TAB delimiters. Again, is this another known 'bug'/limitation of Excel?

  • Can I have damaged a CPU ?

    - by Pascal
    Hey guys, This is a question I asked on Anantech forums, but I just discovered this community and think this question would fit right in. Here goes: I built a PC around a Q9550 1 1/2 years ago (MoBo is an Asus P5Q deluxe). Specs give 2.83GHz, OC'ed it to 3.40 GHZ without any problem (or so I thought) till 2 months ago. Cooling is provided by stock Intel Fan... 2 Months ago, I began to see random crashes, bios saying CPU overheat error... PC would reboot at OC'ed speed without any problem. Since last saturday and a few more crashes, PC won't reboot at 3.40 GHz, and even at stock speed (2.83 GHz), I got core temperatures of (60 C idle, 95 C under load) on the first two cores. This is the 4 core temperatures I am talking about, not the T-CPU which obvioulsy is lower. Fan is running at a steady 2000 RPM. Questions for you : 1. Is 2000 RPM the normal speed of the Intel fan or is my fan somehow broken (which could explain the overheating). In this case, any recommendation for a good fan for OCing ? 2. Hypothesis I fear is the right one: can the CPU have been slowly damaged over time by this OCing, meaning there is nothing much to do except waiting for it to die ? (As a side note, I am surprised that the 9550 is still around 300 $CDN here... Thought it would have been cheaper with all those i3/i5/i7 around). Any help or advice would be more than welcome...

  • Probability of Blade Chassis Failure

    In my organisation we are thinking about buying blade servers - instead of rack servers. Of course technology vendors also make them sound very nice. A concern, that I read very often in different forums, is, that there is a theoretical possibility of the server chassis going down - which would in consequence take all the blades down. That is due to shared infrastructure. My reaction on this probability would be to have redundancy and by two chassis instead of one (very costly of course). Some people (including e.g. HP Vendors) try to convince us, that the chassis is very very unlikely to fail, due to many redundancies (redundant power supply, etc.). Another concern on my side is, that if something goes down, spare parts might be required - which is difficult in our location (Ethiopia). So I would ask to experienced administrators, that have managed blade server: What is your experience? Do they go down as a whole - and what is the sensible shared infrastructure, that might fail? That question could be extended to shared storage. Again I would say, that we need two storage units instead of only one - and again the vendors say, that this things are so rock solid, that no failure is expected. Well - I can hardly believe, that such a critical infrastructure can be very reliable without redundancy - but maybe you can tell me, whether you have successfull blade-based projects, that work without redundancy in its core parts (chassis, storage...) At the moment, we look at HP - as IBM looks much to expensive... thanks a lot best regards Christian

  • Make case-sensitive SMB share case-insensitive

    - by fungs
    I am running a legacy XP app that I would like to move on a network share. It is very simple and works in theory but the server providing the share is based on Linux (cannot configure) and the software does not work correctly because it is programmed case-insensitively, it seems. After some research, network shares behave like the filesystem they use underneath. This is normal. Unfortunately I cannot fix the software myself. Is there any way to turn the case-sensitivity into case-insensitivity for a Windows network drive on the client side? I fould two approaches: First, something like icasefile (http://wnd.katei.fi/icasefile/) that wraps around the program and intercepts the file I/O. This is for UNIX only. Secondly, a proxy virtual file system (e. g. something using Dokan). Unfortunately I couldn't find any suitable fs, the only possibility would be to put a case-insensitive filesystem on an image file and put this on the share using for example lmdisk (http://www.ltr-data.se/opencode.html/#ImDisk). Do you have any better ideas?

  • PLESK PostFix Error Local in maillog, how to troubleshoot

    - by RCNeil
    I'm using the PHP mail() function, using PostFix, on CentOS6, Plesk 10.4, and my email is not getting delivered to a particular address. My personal GMail and Yahoo email addresses receive email from my server fine and do not produce errors. After a wonderful suggestion on here, I checked my mail logs, and this is the error I see : Apr 10 10:26:29 ######### postfix/qmgr[8323]: 19EA21827: from= <[email protected]>, size=645, nrcpt=1 (queue active) Apr 10 10:26:29 ######### postfix-local[8331]: postfix-local: [email protected], [email protected], dirname=/var/qmail/mailnames Apr 10 10:26:29 ######### postfix-local[8331]: cannot chdir to mailname dir name: No such file or directory Apr 10 10:26:29 ######### postfix-local[8331]: Unknown user: [email protected] Apr 10 10:26:29 ######### postfix/pipe[8330]: 19EA21827: to=<[email protected]>, relay=plesk_virtual, delay=0.15, delays=0.11/0/0/0.04, dsn=2.0.0, status=sent (delivered via plesk_virtual service) Apr 10 10:26:29 ######### postfix/qmgr[8323]: 19EA21827: removed [email protected] is the name I've declared in php.ini for sendmail_from = "[email protected]" sendmail_path = "/usr/sbin/sendmail -t -f [email protected]" and the recipient is supposed to be [email protected].

  • (Zywall USG 300) NAT bypassed when accessing in-house-server From LAN Via domain name

    - by mschr
    My situations is like this; i host a number of websites from within our joint network solution. On the network is basically 3 categories: the known public, registered via mac, given static dhcp lease the anonymous lan connections, given lease from specific dhcp range switches, unix hosts firewall Now, consider following hosts which are of interest 111.111.111.111 (Zywall USG 300 WAN) 192.168.1.1 (ZyWall USG 300 LAN) load balances and bw monitors plus handles NAT 192.168.1.2 (Linux www) serves mydomain1.tld and mydomain2.tld 192.168.123.123 (Random LAN client) accesses mydomain1.tld from LAN 23.234.12.253 (Random External client) accesses mydomain1.tld via WAN DNS A records are setup so that both mydomain1.tld and mydomain2.tld points to 111.111.111.111 - and the Linux www serves the http parts with VirtualHost configurations, setting up the document roots pr ServerName, this is not so interesting though.. NAT rule translates 111.111.111.111:80 to 192.168.1.2:80 (1:1 NAT) Our problem follows; When accessing http://mydomain1.tld from outside (23.234.12.253 example host) the joint network - everything is fine, zywall receives requests via port 80 and maps it to the linux host' httpd. However - once trying to go through the NAT from LAN side (in-house, 192.168.123.123 example host) then one gets filtered in the Zywall port 80 firewall. I know this only because port 443 is open for administration interface and https://mydomain1.tld prompts for zywall login. So my conclusion is, that the LAN that accesses 111.111.111.111 in fact are routed to 192.168.1.1 whilst bypassing the NAT table. I need to know how to setup NAT / Policy Route, so that LAN WAN LAN will function with proper network translations instead of doing the 'quick nameserver lookup' or whatever this might be.

  • Excel Help: Data Input Help

    - by B-Ballerl
    Everyday I download data from a site that will have rows each filled with individual data for clients. I'm able to input the data into excel as a whole but after that I'm having trouble figuring out how to put it into a chart. For example Web visits time. So say Client 1 stayed for 5 min increasing his total time on the site to 20 min and Client 2 stayed for 0 min keeping his time of 10 min and they were both registered on new years eve, and R1's last login was today and R2's was yesterday. (R for some reason repersents Client, no idea why...). Client 3 hasn't been on since he registered keeping his total at 4 min So my data would look something like this for Today (20110104) R1,20101231,20110104,20 R2,20101231,20110103,10 R3,20101231,20101231,4 And this for the day before (201101030), R1,20101231,20110102,15 R2,20101231,20110103,10 R3,20101231,20101231,4 I get about 200+ client rows each day where even the names of the Client list are changing. Is it possible to import the data each day and fill it in a excel sheet where the Client number is off on the left hand side in a table, and the amount of time (Whole Number ex. 4) each day it spends on the site extend to the right under it's specific date see Picture? I've manage to create a manual sheet but have been unsucessful at getting excel to do any of it for me. Here are two pictures:

  • RHEL 5.2 installing on ProLiant BL460c - hangs at 'now booting the kernel'

    - by Dr Rocket Mr Socket
    As the title states, I have a problem. This server and the installation disc are also on the other side of the world to me so... So far, I have tried to start the install with the parameters: linux text noapic noacpi no=apic no=acpi which results in the same hang. I have also disabled a PCI ethernet adapter, I am uneasy about disabling the onboard ethernet adapter I do not know if ILO uses this. Anyone have any advice? Much appreciated. EDIT: full output after trying to begin the installation. boot: linux text Loading initrd.img.................. Loading vmlinuz....... Uncompressing Linux...done. Now booting the kernel stays on this for hours EDIT2: adding the 'mem=40960M' (server has 40 gigs of ram) parameter allows it to proceed but the following output directly after 'Now booting the kernal' Memory: sized by int13 0e801h initrd extends beyond end of memory (0x00ef2090 > 0x00000000) disabling initrd Console: 16 point font, 400 scans Console: colour VGA+ 80x25, 1 virtual console (max 63) pcibios_init : BIOS32 Service Directory Structure at 0x000ffee0 pcibios_init : BIOS32 Service Directory entry at 0xf0000
