  • Is it possible to be a professional studying on your own?

    - by Marc Jr
    I read economics at university(nothing to see with linux, isn't it? :P). I have some basic knowledge about booting process, Linux Kernel compiling from source and stuff like that. But of course I have still much to learn sometimes some errors appears and "voila" I am lost. I had: Ubuntu, Fedora, OpenSuse, Arch.. using Gentoo now. I'd like to know what you linux users, professionals, administrators... would think it is the best way to learn linux in a professional way. Is it worth studying it and passing the LPIC test enough to work in the linux world? or do I need going to IT uni? I've heard LFS is a good way of learning about linux, is that real? I've been thinking about getting to LFS learn about more deeply about the linux process and learning scripts. It is possible to do this way? if anyone has a tip or a good way of doing, maybe someone did it. Any tip is very welcome. Words from a person in love with linux. :D The best, Marc

  • Windows Server 2008 (sp2) stops responding on network share requests from Windows Vista and 7 client

    - by Peter LaComb Jr.
    I have two Windows Server 2008 SP2 machines (TFS and TFSBUILD). Periodically, the TFSBUILD server shares (\TFSBUILD\ShareName or \TFSBUILD\C$) become unresponsive to requests from Windows Vista (Server 2008) and Windows 7 client requests. Windows XP machines are still able to connect. No events in the server log indicate any problem. A simple restart corrects the issue temporarily, but it always returns. No, it is not this http://support.microsoft.com/kb/976266 (we aren't using that software). All anti-virus software has been disabled, firewall is disabled by policy. No other network activity is affected. Any help would be greatly appreciated.

  • Maintenance Plan Reporting - Append To File - Clean Up?

    - by Adam J.R. Erickson
    Background: (SQL Server 2005, Standard Ed.) I have a maintenance plan running backups, taking a full backup 1/day, and t-log every 15 minutes. I have it set to create a text file report of each run, but that creates A LOT of files on the file server. These are hard to sort through, which makes them less useful. Question: There is an option in "Reporting and Logging" settings for appending all logs together, but how do you clean this out? If you're appending to the same log file every time, how should you make sure this file doesn't grow indefinitely? Is there a build-in function to clean out portions of appended logs like there is for cleaning out individual old log files?

  • Target line parameters for shortcuts in Windows Explorer?

    - by Charles E. Gates Jr.
    I am using Windows 7 and I am looking for a list of the different parameters to use in the Target line of a shortcut in Windows Explorer. For example: /n forces it to open a new window, even if it duplicates a window that is already open. /e uses Windows Explorer view (multi-paned) /root,X restricts Explorer to showing only the contents of file folder X (and its sub-folders) /select,Y automatically selects Y (either a file or folder). What other parameters exist? I have been searching online and cannot find anything.

  • How do I set up a shared directory on Linux?

    - by JR Lawhorne
    I have a linux server I want to use to share files between users in my company. Users will access the machine with sftp or secure shell. Here is what I have: cd /home ls -l drwxrwsr-x 5 userA staff 4096 Jul 22 15:00 shared (other listings omitted) I want all users in the staff group to be able to create, modify, delete any file and/or directory in the shared folder. I don't want anyone else to have access to the folder at all. I have: Added the users to the staff group by modifying /etc/group and running grpconv to update /etc/gshadow Run chown -R userA.staff /home/shared Run chmod -R 2775 /home/shared Now, users in the staff group can create new files but they aren't allowed to open the existing files in the directory for edit. I suspect this is due to the primary group id associated with each user which is still set to be the group created when the user was created. So, the PGID of user 'userA' is 'userA'. I'd rather not change the primary group of the users to 'staff' if I can help it but if it is the easiest option, I would consider it. And, a variation on a theme, I'd like to do this same thing with another directory but also allow the apache user to read files in the directory and serve them. What's the best way to set this up?

  • Do I need to recreate statistics if I had to drop them to add a foreign key

    - by Adam J.R. Erickson
    I have a database which had all it's foreign-key relationships dropped at some unknown time in the past (don't ask). I have an old copy of the database which isn't good to restore from, but the schema has the relationships. I'm working from that to create a script to restore the keys. In updating the tables, I've had to drop statistics from several tables. Do I need to manually recreate those, or can I just run the statistics update procedure when all the tables are updated?

  • How can I install git on RHEL 6?

    - by JR.Xyza
    I'm trying to install Git on a RHEL6 development server, I have experience with Ubuntu but this is my first time working with RHEL (I'm a developer trying to fill in for a recently departed Linux Sysadmin). I've set up two additional repos (EPEL and IUS) for other packages needed for a Magento install. Output of yum repolist: [root@box]# yum repolist Loaded plugins: product-id, security, subscription-manager Updating certificate-based repositories. repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 7,841 ius IUS for RHEL 6Server - x86_64 135 Most of what I've read indicates a simple 'yum install git' should work with EPEL enabled, but I get the dreaded [root@box]# yum install git Loaded plugins: product-id, security, subscription-manager Updating certificate-based repositories. Setting up Install Process No package git available. Error: Nothing to do Same goes for git-daemon, etc. I've tracked down a number of git RPMs such as this one at repoforge but they require a train of dependencies that seems to never end. I've also toyed with compiling it manually but the rabbit hole to get make working seems to go even deeper. I'm convinced there's a simple oversight somewhere keeping me from being able to install from the EPEL repo, but I'm a rookie at all this. Thanks in advance for help/pointers/additional resources.

  • How secure is using "Normal password" for SMTP with connection type = STARTTLS?

    - by harshath.jr
    I'm using an email client for the first time - for the most part I've always used gmail via the web interface. Now I'm setting up thunderbird to connect to an email server of my own (on my own server, own domain name, etc). The server machine (and the email server on it) was preconfigured for me. Now i figured out away by which I'm able to send and receive email, but I noticed that in the outgoing and incoming servers section, the connection type was STARTTLS (and not SSL/TLS), and the Authentication Type was "Normal Password". Does this mean that the password will be sent across in plain text? I'm very paranoid about security - its the only way that it works for me. Can someone please post links that explain how SMTP (my outbound server) and IMAP (my inbound server) servers work, and what connection type means what? Thanks! PS: If this question does not belong here, please redirect me.

  • Windows 7 Desktop as Bluetooth Mixer

    - by J.R. Lillard
    I would like to stream all the audio from my Droid X2 to my desktop running Windows 7 via bluetooth. When I pair the two devices I can make this work but the audio plays through the internal speakers. I am actually wanting to listen to everything through a pair of bluetooth headphones. The end result would be that I could listen to music from my phone but easily pause it to listen to audio from the desktop instead. So far I have not had any luck. I thought about connecting the line out to the line in so I could monitor the line in from my headphones. My current setup is wiring the phone to the line in and then monitoring the line in through the headphones. I'm just wanting to eliminate the wire and go wireless the whole way. Is there something in Windows that prevents it from taking an inbound audio stream and sending it out another device?

  • Using relative path in PHP.INI doc_root -- getting No Input File Specified -- running as fastCGI

    - by J.R.
    I'm attempting to run php-cgi under LightTPD on Windows with my doc_root set to one directory up (doc_root = "../Docs") -- however, I get "No input file specified". I've set cgi.fix_pathinfo, and all the other tricks I could find with no success. If I set doc_root to an absolute path, it works fine. How can I make this work? If any additional information is required, I'll gladly provide it. Thanks in advance.

  • Postfix throttling for outgoing messages

    - by Sergey Kovalev
    I need Postfix to send outgoing messages (from local PHP) with a certain rate. Say, one message in 120 seconds. Any messages exceeding this rate should be queued (delayed) and delivered later. Policyd is not what I'm looking for. I don't need limiting overall number of messages sent. I need a pause (120s) between any two messages beeing sent. Tried this config, but it's not working: initial_destination_concurrency = 1 default_destination_concurrency_limit = 1 default_destination_rate_delay = 120 default_destination_recipient_limit = 1 default_process_limit = 1 Any suggestions?

  • iSCSI SAN Implementation with several ESXi hosts and two Equallogic SANs

    - by Sergey
    I work for a small state college. We currently have 4 ESXi hosts (all made by Dell), 2 EqualLogic SANs (PS4000 and PS4100) and a bunch of old HP Procurve switches. The current setup is very far from being redundant and fast so we want to improve it. I read several threads but get even more confused. The Procurve Switches are 2824. I know they don't support Jumbo Frames and Flow Control at the same time, but we have plans to upgrade to something like Procurve 3500yl. Any suggestions? I heard Dell Powerconnects 6xxx are pretty good but I'm not sure how they compare to HPs. There will be a 4-port Etherchannel (Link Aggregation) between the switches, and all control modules on SAN will be connected to different switches. Is there anything that will make the setup better? Are there better switches then Procurves 3500yl that cost less than 5k? What kind of bandwidth can I expect between ESXi hosts (they will also be connected to 2824 with multiple cables) and SANs?

  • Looking for QNX compatible server hardware

    - by Sergey Sobolev
    Can you help me to find compatible modern server for QNX, please? This is quite rare OS, so most of the hardware vendors do not have compatibility information. It would be very helpful to me if you can do the following: Download iso http://www.qnx.com/download/download/19602/qnxsdp-6.4.1-x86-200905201802-nto.iso burn to cd Start from cd press F2 - try from CD start Utilities/Terminal run sloginfo /tmp/sloginfo.log; get_hw_info; pci -vvv /tmp/pci-vvv.log send logs from /tmp/ to [email protected] with system model/build I will summarize results afterwards and post them here. I'm especially interested in Fujitsu RX100 S5 as it looks like one of the most compatible servers with frontally accessible HDDs.

  • Intel Atom overheating in ASUS EEE Box 1501P

    - by Sergey L.
    I have had an ASUS EEE Box 1501P for just a little bit over a year. Of course it breaks 2 months after the warranty runs out. http://www.asus.com/Eee/EeeBox_PC/EeeBox_PC_EB1501P/ I have been using the box as a Home Media Center. Running mostly 24/7 often pausing a video overnight. Since last week the fan started running extremely loud. After some digging I found that the Intel Atom CPU in it is overheating and the built-in sensor is reporting temperatures way over 105°C. This got me worried, so I took the unit apart. Completely vacuumed the heat sink, oiled the fan, but the unit is still showing the same behaviour. After turning it on and just observing the hardware monitor in the BIOS the temperature slowly rises from 40°C to over 95°C in appx 5 min. I am running the newest BIOS and a lightweight Linux OPENELEC OS with XBMC on it. Now I am wondering if it could be a faulty heat sensor in the Atom. Recommended running temperature is up to 85°C, but I have not detected any performance hits when running at the above mentioned 105°C and there seem to be no software faults. How can an Atom with an attached heat sink and a fan running at full capacity even get this hot in the first place at 0 load? Aren't those things designed to generate virtually no heat? Could it be a faulty heat sensor? What shall I try to fix this? I would prefer not to damage the CPU, since it is hard fused into the motherboard and cannot be replaced. I could remove the heat pipe/heat sink, but it is getting hot, so heat is properly transferring from the CPU to the heat pipe, the fan is running at full capacity, is recently oiled and warm air is making it out of the exhaust. Edit: One more note: The North-bridge (or whatever it is called nowadays) is on the same heat pipe.

  • How to protect ejabberd from bruteforce attacks?

    - by Sergey
    It writes this in logs: =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.467.0>:ejabberd_listener:281) : (#Port<0.4384>) Accepted connection {{10,254,239,2},51986} -> {{10,254,239,1},5222} =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.1308.0>:ejabberd_c2s:784) : ({socket_state,tls,{tlssock,#Port<0.4384>,#Port<0.4386>},<0.1307.0>}) Failed authentication for USERNAME =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.1308.0>:ejabberd_c2s:649) : ({socket_state,tls,{tlssock,#Port<0.4384>,#Port<0.4386>},<0.1307.0>}) Failed authentication for USERNAME It doesn't write IP with a failure. And strings "Accepted connection" and "Failed auth.." may even not stand nearby (as I think on heavily loaded servers) to be able to use fail2ban. What to do? And how jabber servers (using ejabberd) are protected?

  • Mutt seems to sync to Gmail IMAP only on quit

    - by Sergey
    I am using Mutt 1.5.20 in Mac OS X Terminal. I have a Google mail account whose mail I fetch via IMAP. I also use a Gmail notifier app to notify me of new e-mail messages. My experience with Mutt dates no later than 1 week. The trouble is this: When my Gmail notifier tells me about a new e-mail, I hit the Terminal to open Mutt. I can read the message and Mutt will mark it as read. However, Google's servers are not told that the message is read until Mutt is closed. Thus, my Gmail notifier continues to show a misleading unread count. How can I force Mutt to synchronize with IMAP without having to quit every time I finish reading my e-mail? Preferably the sync will occur instantaneously, but a periodic sync would be satisfactory as well.
