• Rail's FileStore with Linux Disk Caching or RAMdisk?

  - by Yo Ludke

  I have a Ruby on Rails application that stores it's catched files on the filesystem (Rails file-system cache). I was thinking about changing to memcached Store, but a short test shows it isn't a big difference in speed. From linuxatemyram.com I learned a bit about file caching. On the current machine there would be around 40..45GB RAM left which isn't needed for the application and which can be used to linux-disk-cache this rails file cache store. The disk is a RAID10 system with almost 120MB disk perfomance. How can I tell Linux to use free RAM more deliberately and not to be shy about using it? Do think it's necessary to adjust a sysyctl/.. value here, or would I have performance advantages to put the File Store root diretory on a ramdisk? (Loosing the cache during a reboot wouldn't be a problem)

• Using e-mail address as user name for SMTP and POP3

  - by PeterMmm

  I have a exim4 setup as SMTP. My user naming schema is to name all mail users for this server as m001, m002, m003, ... and then redirect to a real e-mail address with virtual domains. How can I allow my users to authenticate with exim to send mail using either their system user name (m001) or the email address ([email protected])? User login information for m001 are stored in linux system files (passwd, shadow). They are linked thru entries in a virtual address table for each domain that this server can serve: # /etc/exim4/virtual/example.com m001: [email protected] m002: [email protected] m003: [email protected] The same can be applied to qpopper ?

• Connect to wired and wireless networks at same time, Ubuntu

  - by Gary Chambers

  Currently, I have a media PC running Ubuntu 10.04 that I am trying to connect via a wired network cable directly to a NAS box, and wirelessly to the router. This works no problem after I run sudo /etc/init.d/networking restart but I can't get both interfaces to come up on system startup. My /etc/network/interfaces file reads as follows: auto eth0 iface eth0 inet static address 10.0.1.2 netmask 255.255.254.0 broadcast 10.0.1.255 network 10.0.1.0 auto wlan2 iface wlan2 inet dhcp As I say, I know this works, because I can get it to work by restarting the network interfaces, but I can't bring them both up on system startup. Does anyone know why this might be?

• How to execute a shell script on startup?

  - by vijay.shad

  I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

• How to perform fresh linux install while preserving software raid and user accounts

  - by slayton

  I have a system with two software raid arrays. The OS is Ubuntu 9.04 and is no longer receiving updates. I'd like to update the system to 12.04 rather than trying to do the automatic update from 9.04-> 9.10-> ... -> 12.04. My main drive has 2 partitions that are mounted at / and /home. Is it possible to do a fresh install of linux to the partition where / is mounted while preserving user accounts and preferences (such as passwords, home dir locations, etc...)? Additionally what do I need to do to keep my software raid array intact following the OS re-install?

• Default Critique branch office setup: VPNTunnel->HQ, subnets for VOIP/PC, + several Q's

  - by CHickenTaragon

  We're setting up a new branch office. * ~10 users. * Each user has a VOIP phone provided by a hosted solution. * Users need access to resources on HQ (located in another state), so setting up VPN tunnel * HQ only supports certain Cisco/Juniper devices. VOIP provider only supports SonicWall, so current plan is to have two routers w/ separate subnets for VOIP vs. PC traffic. * PC's will plug into pass-thru Ethernet jacks on the VOIP phones, but the phones vs. PC's will point to different subnets. * Cable Modem is 50Mbps / 5Mbps DOCSIS 3.0 business line w/ 5 static IP's. * Each of the 2 subnets will map to one of the 5 public IP's. * May or may not also need to support a VPN tunnel with a second branch office because of a file server they have there that some in the new office use. I'm pushing to have them move the files to a server on the HQ's network so we don't have to worry about setting up an additional tunnel. Questions: Do you foresee any issues with the below set-up? Router recommendations by HQ IT staff: Cisco Router 2811, or Juniper SSG5 or SSG20. Any recommendations about these routers? We need Wi-Fi too – looks like the above routers have models that support this, any reason not to use this? Users need to be able to work from home. If so, how is authentication handled? Right now we use AD credentials for the HQ's domain, but we currently don't plan to have an AD system in the new location since it's only 10 users. We can't tie the authentication system from the new location's router to the AD system of the HQ. All the PC's that will be in the new location are currently in the existing office that is closing down, and are already joined to the domain of the HQ. Please confirm: this + the VPN tunnel will be sufficient for them to connect to authenticated resources on the HQ's network from the new location, correct? Mainly SQL servers and file servers, and a few remote desktop sessions. I'm sure I'll have some more questions, but can't think of them right now.

• How to recover a MySQL InnoDB table?

  - by Kau-Boy

  When I try to launch the Plesk administration page of you server I get the following error: ERROR: PleskMainDBException MySQL query failed: MySQL server has gone away The MySQL Server is working well. Although it seems that the plesk database is somehow corrupt and any action on this database results in a restart of the mysql process, so even queries to other databases on the same MySQL server will be lost. If I try to connect to the plesk database using phpMyAdmin, I can only see the number of tables, the database had originally. But I am not able to open the tables listing. As soon as I try it, the mysql process crashes again. Trying to connect to the database using ssh works. I can even run a SELECT statement against any table an get a result. I don't know if it is an plesk error or an error of the psa database or even the MySQL server. Can you give me any tips on how to recover the plesk system. Should I try to repair the Plesk installation before. And if so, how can I do it and will all my settings get lost doing it? EDIT: Trying to dump the database, I get the following error: mysqldump: Got error: 2013: Lost connection to MySQL server during query when using LOCK TABLES EDIT: I could find out, that the table 'data_bases' is responsible for the crash of the MySQL server process. But trying to repair it using a REPAIR TABLE statement doesn't work. EDIT: I now dropped the whole database and restored it from a dump. But why I try to recover the data_bases table I get the following error: ERROR 1005 (HY000) at line 24: Can't create table './psa/data_bases.frm' (errno: 121) I am not able to create the table again. Somewhere in the MySQL system there is still some information about this table. I tested the same thing locally. If I just delete the table files and then try to create the table again I get the same error. If I drop the table through MySQL, I can create the table again afterwards. But trying to drop the table using MySQL the whole MySQL system crashed. Is there any way to solve that issue?

• Centralize proxy settings for all the application on my workstation

  - by Leonardo

  As a consultant, I used to work at different clients premises. It happens frequently that most of them has specific proxy settings, but not all the application I have installed on my laptop get settings from system preferences, for allowing me to change settings in one place. Some of them bypass system preferences completely, proposing their own mask for entering specific data such as username, host and password. I am looking for a convenient and not much intrusive way to share a common access point on which I could enter data, and maybe persist them. An 'automatic' switching would be ideal, for example based on some network identification, but there's no problem for me to enter data manually. I am not an IT expert, but to explain myself clearly, I am looking for a solution like .pac file is for browsers. Relevant OS I am using are MacOSX and Linux (Ubuntu).

• TeamViewer: How to disable color dithering for low-bit-depth screen settings

  - by gogowitsch

  I am using Terminal Services and TeamViewer a lot to access other computers, partly over slow networks. The problem described below is not affected by which of the two remote access services I am using. When accessing Windows 7 Professional machines, a great deal of text is hard to read as the background is dithered. Even for exactly the same colors, Windows 2003 does not seem to dither at all, but to choose the closest available color. I strongly prefer the latter, as I don't care for the exact colors, I just want to be able to read easily. I am not sure whether this is operating system-related. The programs on the remote systems do not allow me to change the color choices for the various backgrounds to anything sane. Is there a way to disable this color dithering using some target operating system setting that will do the trick for both Terminal Services and TeamViewer?

• Choosing A Power Supply [closed]

  - by Geeks On Hugs

  Possible Duplicate: Power Supply Capacity Formula How can I check if my system needs more PSU power? I'm not sure if it's OK or not to ask a hardware question here. If not please let me know a good place but I've always got good info here so I thought I'd give it a shot. I'm custom building a new workstation for coding (Linux/Eclipse). How do I determine how much power the power supply needs? I'm building a mini ITX system on a budget and so I need to get as small as possible that is sufficient. I'll have a mini itx mobo with on board wifi and bluetooth, 8 GB RAM, an Intel i3 3.1 Ghz processor, 64 GB SSD and a slim optical drive. In the future I might add a descrete GPU, 16 GB RAM, 128 GB SSD. What is the minimum power I need and how do I calculate that?

• Windows Server 2003 - passwordless access to \\myhost\ but not \\myhost.mydomain.net\

  - by Charles Duffy

  I have a Windows Server 2003 system on which passwordless access to local UNC paths is possible using the server's unqualified hostname or its IP address, but not via its FQDN -- even when the hosts file is used to map that FQDN directly to 127.0.0.1. That is: \\127.0.0.1\ - passwordless \\myhost\ - passwordless \\myhost.mydomain.com\ - brings up an authentication dialog Unfortunately, I have a local application trying to resolve UNC paths including the host's FQDN. I've tried resolving myhost.mydomain.com to 127.0.0.1 in both hosts and lmhosts, and calling ping myhost.mydomain.com at the command prompt gives the appearance that this resolution has taken effect; even so, attempting to open \\myhost.mydomain.com\ from Windows Explorer brings up a password prompt, while \\127.0.0.1\ does not. The system is using an OpenDirectory server (Apple's Kerberos+LDAP directory service) for authentication.

• EMC CX3-10c Fault Condition won;t clear

  - by ITGuy24

  We have an old CX3-10c from Dell that had both Standby Power Supplies (SPS) fail. This obviously caused a fault on the system and disabled the cache. We have replaced the SPS's and they test fine as do all other components. Problem is there is still a fault on the "Enclosure SPE [SPE3]" despite all the component in the enclosure showing as good. I was on the line with Dell Gold support for 3 hours yesterday, they have had me restart the SPs multiple times, as well as reseat the power supplies, even shutdown the system completely and power it back on. All to no avail. Fault remains and cache cannot be re-enabled so long as the Fault is present. Any suggestions on clearing this erroneous fault?

• How Will Mac OS X Snow Leopard Upgrade Work?

  - by Blaenk

  I am relatively new to Mac OS X. I got my MacBook in January, and I have never experienced a new version of the operating system. I am wondering if I should simply upgrade my install to Snow Leopard. I come from Windows where it is advised to do a complete reformat. I would rather not do this, however, and I have a feeling that due to Mac OS X' POSIX based nature, it might actually not be all that bad if I upgrade. I guess if things end up screwing up I can simply go ahead and reformat, but I am wondering what it is like to upgrade systems running Mac OS X. I wouldn't want my Snow Leopard installation to be somehow deficient due to certain inconsistencies within the system.

• Debian: Firefox or Iceweasel default printer for POS station

  - by Bubnoff

  Context Using Debian 6.04 "Squeeze" as POS station. There are two printers installed: Network printer and a receipt printer It absolutely must be able to print by default to the receipt printer on a certain website though the system default is a network printer. In Debian ...it doesn't. Problem I've set up XP, 7, Ubuntu and even Mac OSX this way, so I'm no stranger to setting Firefox up this way ...same Iceweasel/Firefox settings ...complete fail. Always uses system default no matter what the settings, or, which printer you print from. To get this to work on other systems you do this: Print a page in Firefox using desired printer. Ensure print.save_settings is true. Firefox remembers last printer used Set print.always_print_silent = true The end. This works on every OS I've set up ....except Firefox and Iceweasel in Debian. My only recourse seems to be to set the receipt printer as default or go back to bloaty Ubuntu/Mint ...etc.

• Can I uninstall Qmail when I switch to Gmail Apps

  - by Saif Bechan

  I am not going to run a mail server anymore on my system. I am going to switch to Gmail. Can I then just uninstall Qmail or my previous mail server programm. I want to be able to send email from PHP. And I also want to get the email that Logwatch sends me from within the system. Basically, to have your server send email do you need an email server? Or will Gmail cover all of this.

• Vmstat indicates memory is disappearing

  - by jimbotron

  I wanted to profile the memory usage of a script. Here's the output before it was running: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 186660 39460 439052 0 0 0 2 1 1 0 0 100 0 Here's the output while the script is running, at the point where free memory was at its lowest value: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 11464 40312 473524 0 0 0 2 1 1 0 0 100 0 So free memory dropped by about 175 MB, and I expected that buff would increase by that amount. But it seems the other columns changed by relatively negligible amounts - how is this possible? Am I interpreting this wrong, or is some memory just not being accounted for in this output?

• Asus M4A79XTD-EVO / AMD Phenom II X4 965 Crashes / BSOD / Hangs / Restarts

  - by Tiby

  I'll try to be as concise as possible because I have a lot to say about my problem, but I'd rather say it when asked or when I feel it's necessary, just to make this initial reading clearer. For about a year and a half I have periods when my system has all the problems in the title (I'll use the word 'crash' for either one). I'll list some patterns and what I tried to do and what were the results, but the list is not exclusive: usually it crashes when a CPU-intensive operation is in progress, like a game or video encoding or HD movie rendering, but also sometimes crashes when I'm doing nothing after a first crash the system is very unstable and sometimes it crashes even during POST, or doesn't boot at all Some months ago I went to a local service (one that you just put your computer on the table and sit there with a guy and trying to figure out the problem, very rare these days) and they used OCCT and it crashed every time he changed some part to test it out (PSU, RAM, video card, HDD). The last one was the CPU. They changed the CPU and it didn't crash any more. Then when they put my CPU back, it also didn't crash. We figured that the trouble was the thermal paste (probably some 2 years old) because it was the only thing changed while testing. Up until 2 weeks ago, I haven't had any more problems. 2 weeks ago the problems reappeared. I changed again the thermal paste, put some Arctic Silver 5, and for about a week everything worked perfect (tried some games, video encoding, no more crashes). But again it started crashing in the same fashion as the first time. But now, instead, I figured out a very odd behaviour: when I start some of the apps above, in most cases it crashes if I start OCCT and turn on the CPU test, and run any of the programs above, it doesn't crash, even if the CPU is on 100% load (and 65-70 degrees Celsius temperature) if I shut down OCCT and continue using the programs, it crashes in a very short period of time (even if the CPU is on 5-10% load and 40 degrees) There are so many patterns and temporary solutions that I figured out in this year and a half period of time, that I can't include them all because I don't know which one are more relevant, but I'll happily provide any details you ask. My system is: CPU: AMD Phenom II X4 965 (3400 MHz - 125W) MB: ASUS M4A79XTD - EVO RAM: Corsair Vengeance 8 GB (2 x 4GB) CL8 1600MHz Video: HIS Radeon HD5770 1GB PSU: Corsair 750W HDD: Western Digital 1TB OS: Win 7 Enterprise 64 BIT (also tried with Windows Server 2008 R2 Trial and Win XP)

• How to get a maximum file size of VZFS parition?

  - by Nulldevice

  I have a VPS hosting with a VZFS file system. How can I determine maximum file size of VZFS partition? UPD: Free space (or total space) is not what i need. Sometimes file cannot occupy a hole partition volume - fat16 with 2Gb limit is a good example. I need to use a large database file (say, 64Gb) and so I need to know if a file system of VPS hosting will cope with it. It is easy to calculate for an ext3 filesystem using tune2fs, but VPS uses VSFS by Virtuozzo, and it is documented bad. Is it any generic way to calculate maximum file size for some filesystem in linux?

• My computer has gone horribly slow, how can I dignose whats wrong?

  I have a computer based on AMD processor & 512 MB RAM. Lately the computer has gone horribly slow. I did many tricks but was of no avail. So, I reinstalled my Operating system - Win XP SP3, still the the response is very slow. I checked if there are any background applications consuming resources. There was nothing suspicious. I removed all the applications on start, still the computer is slow. I've heard that AMD processor based systems show this behavior when they get aged. Is it true? Should I just buy a new system?

• Windows 7, Drivers, Cloning and Sysprep

  - by Frank Thornton

  I have Windows 7 working on one machine but when I move it off to the new machine it crashes. If this is a driver issue do I need to download the drivers and install them first? Or do I install Windows 7 on the new machine first then copy the drivers folder over to the other disk so it will boot up correctly? EDIT: I was trying this as well: http://www.todo-backup.com/support/tutorial/redeploy-system-to-dissimilar-hardware.htm EDIT: I tried sysprep but on bootup I see the Windows logo then the system crashes. I can stick the drive back in the old hardware and it runs fine.

  Hello! I installed Mac OS X Server 10.6.0 in VMWare Fusion the other night and it worked perfectly, until I ran Software Update. I upgraded to 10.6.6 through the combo updater, and now when I start the VM it says: "The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point." I've switched the operating system in the options to OS X Server 32bit, 64bit, and even to Windows 7, and nothing has worked. Does anyone have any ideas?
