• "setpci: command not found" in CentOS

  - by spoon16

  I'm trying to configure my Mac Mini running CentOS 5.5 to start automatically when power is restored after a power loss. I understand the following command has to be executed: setpci -s 0:1f.0 0xa4.b=0 When I run that command on my machine though I get bash: setpci: command not found. Is there a package I need to install via yum or something? I'm not seeing a clear answer via Google and I looked at the man page for setpci and it doesn't mention anything. Also, does this command need to be run every time the machine starts or just once?

• Realtek/Intel NIC transfer speed

  - by thepurplepixel

  I have just purchased a Gigabyte GA-X58A-UD7 motherboard, and it has dual Realtek RTL8111D gigabit LAN ports. I also have an Intel PRO/1000 MT PCI gigabit network card lying around from an old desktop. I've heard that Intel PCI-E network cards will often outperform Realtek, Marvell, or other non-Intel on-board network adapters, but my question is will the PRO/1000 MT PCI card outperform a single Realtek RTL8111D gigabit network adapter in terms of transfer speed, or should I keep what I have/buy a PCI-E Intel network adapter?

• How to reboot a WindowsCE5 device?

  - by Stijn Sanders

  Is there a way to force a device running Windows CE 5.0 to reboot? I remember Ctrl+Alt+Del from the old days on PC's, but I don't know if there's a keyboard-combination I could use on this Datalogic BlackJet, and I can't seem to find a reset pin-hole. I tried taking the battery out, and waiting a few hours, but that totally reset the device from ROM, undoing all setup I'd done.

• How do I view the job queue in lftp after it has moved to a background process?

  - by drpfenderson

  I've just started using lftp for remote transferring files on my Raspberry Pi running Debian. I know how to transfer the files, and use queue and jobs to add and view transferring files. However, I'm not actually sure on how to view these transfers once lftp moves to the background. The lftp man page mentions how lftp is moving to the background, but when I open a new instance of the program from shell and type jobs, the queue is empty. However, I can clearly see using my file manager that the transfers are still happening, as the files are there and growing in size. I'm guessing that when I reopen lftp, it's just opening a new instance that isn't connected to the nohup mode lftp that has the active queue. I've tried searching various places, but no one else seems to have this particular issue. So, I guess what I'm asking is twofold: Is there a way to easily attach to the background lftp process to view the current jobs list? If not, is there a way to view this at all?

• Migrating Email to new hosting.

  - by Ben C

  I've made a site for a charity, and now have to move hosting for them. They have 5 or so email addresses on their current hosting account, which will of course need to move too. What's the best way to migrate their email addresses to the new server without too much hassle for them? They use POP3, so should I just create the account on the new server and then get them to update their settings? That won't remove their old emails from Outlook Express, will it?

• Torque and maui node status

  - by Lafada

  I am new for torque and maui. I was checking for node state to looking for which nodes are free and which nodes are in use. For torque one command is pbsnodes. Which gives status and other info related to node. When I was checking for maui then I found command diagnose -n which also shows status of the node. I was wondering between these 2 status. Both are giving different status for the same situation. When I do man pbsnodes I got the possible states for node "free", "offline", "down", "reserve", "job-exclusive", "job-sharing", "busy", "time-shared", or "state-unknown" But this type of different state I cant find for diagnose -n. How pbsnodes and diagnose -n get the status for node. Is there any database like xCAT use for torque or maui? Thx in advance for your valuable time.

• VSFTPD and Implicit SSL

  - by Luma

  Hi Everyone, I have a Debian Dedicated server and I want to enable Implicit SSL on it using VSFTPD and I am having a hard time. I have read online and the only thing I can really find is how to enable SSL and in the man pages it lists one implicit ssl command. but since Implicit ssl uses a second listener (990 by default) I have no idea how to make it work on Debian. Has anyone managed to get this working? Here is my config: listen=YES anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 connect_from_port_20=YES pam_service_name=vsftpd ssl_enable=YES allow_anon_ssl=NO force_local_data_ssl=NO force_local_logins_ssl=NO ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO rsa_cert_file=/etc/ssl/certs/vsftpd.pem if I include Implicit_SSL=YES the server won't even start. thanks

• Snow Leopard on Core Duo

  - by Brendan Foote

  The first run of MacBook Pros have Core Duo processors, whereas all the ones after that have Core 2 Duos. Apple says Snow Leopard only requires an Intel processor, but will a first-gen MacBook Pro get enough of the improvements to be worth upgrading? This is similar to the question about Snow Leopard on an old iBook, but it differs because this processor is supported by Apple, but seems counter to the 64-bit theme of the upgrade.

• Tuning Linux IP routing parameters -- secret_interval and tcp_mem

  - by Jeff Atwood

  We had a little failover problem with one of our HAProxy VMs today. When we dug into it, we found this: Jan 26 07:41:45 haproxy2 kernel: [226818.070059] __ratelimit: 10 callbacks suppressed Jan 26 07:41:45 haproxy2 kernel: [226818.070064] Out of socket memory Jan 26 07:41:47 haproxy2 kernel: [226819.560048] Out of socket memory Jan 26 07:41:49 haproxy2 kernel: [226822.030044] Out of socket memory Which, per this link, apparently has to do with low default settings for net.ipv4.tcp_mem. So we increased them by 4x from their defaults (this is Ubuntu Server, not sure if the Linux flavor matters): current values are: 45984 61312 91968 new values are: 183936 245248 367872 After that, we started seeing a bizarre error message: Jan 26 08:18:49 haproxy1 kernel: [ 2291.579726] Route hash chain too long! Jan 26 08:18:49 haproxy1 kernel: [ 2291.579732] Adjust your secret_interval! Shh.. it's a secret!! This apparently has to do with /proc/sys/net/ipv4/route/secret_interval which defaults to 600 and controls periodic flushing of the route cache The secret_interval instructs the kernel how often to blow away ALL route hash entries regardless of how new/old they are. In our environment this is generally bad. The CPU will be busy rebuilding thousands of entries per second every time the cache is cleared. However we set this to run once a day to keep memory leaks at bay (though we've never had one). While we are happy to reduce this, it seems odd to recommend dropping the entire route cache at regular intervals, rather than simply pushing old values out of the route cache faster. After some investigation, we found /proc/sys/net/ipv4/route/gc_elasticity which seems to be a better option for keeping the route table size in check: gc_elasticity can best be described as the average bucket depth the kernel will accept before it starts expiring route hash entries. This will help maintain the upper limit of active routes. We adjusted elasticity from 8 to 4, in the hopes of the route cache pruning itself more aggressively. The secret_interval does not feel correct to us. But there are a bunch of settings and it's unclear which are really the right way to go here. /proc/sys/net/ipv4/route/gc_elasticity (8) /proc/sys/net/ipv4/route/gc_interval (60) /proc/sys/net/ipv4/route/gc_min_interval (0) /proc/sys/net/ipv4/route/gc_timeout (300) /proc/sys/net/ipv4/route/secret_interval (600) /proc/sys/net/ipv4/route/gc_thresh (?) rhash_entries (kernel parameter, default unknown?) We don't want to make the Linux routing worse, so we're kind of afraid to mess with some of these settings. Can anyone advise which routing parameters are best to tune, for a high traffic HAProxy instance?

• Windows Updates Folders (With Strange Names) in C drive

  - by Kanini

  I have a Windows XP Professional SP 3. In my C drive, I have a lot of folders which I do not know why they exist. Sample these names - 1da9de11ed14f5da3b6ace4e25f5 a0332ef3abcaf03e49 What are they? Why are they created? Can I delete them? And no, "Windows XP is an old system. You need to skip, hop and jump to Windows 7" is not a valid answer. :-)

• Remap paths used in Windows Movie Maker projects

  - by Fuxi

  I need to rebuild path structures for old Windows Movie Maker projects under a new Windows 7 install. The problem is that those projects refer to files of a certain file path that can't be rebuiltd in Windows 7 ("Documents and Settings" is blocked). Is there a way to batch convert those projects with updated paths? Some file specs of the WMM file format (for coding a little utility) would be helpful as well.

• signed software :: installer -- system software and package installer tool (Apple *.pkg)

  - by fyodor78

  Does anybody know a few details about signed software and /Applications/Utilities/Installer.app? I didn't find more at Wikipedia (https://secure.wikimedia.org/wikipedia/en/wiki/Installer_%28Mac_OS_X%29) and the UNIX-Manual (man 8 installer). I have here a valid signature from iLife 11 Installer.app (http://i.imgur.com/Y3raY.jpg). Does this mean I can be 100% sure that nothing is modified? It means I can trust this PKG because signed by Apple? Or did I get something wrong?

• File sync over LAN

  - by Jack

  At the moment, I'm using Dropbox on my computer and Dropsync on my Android phone (over WiFi) to one-way sync the files (such as photos/app backups) on my phone to the Dropbox servers which are then synced to my computer. I like the features of Dropsync which can be set to sync only when the phone is charging and the WiFi is on. So everytime I charge my phone, i know my files are being backed up. Now I'm wondering if there's a similar app/program combo or something that can do what I'm currently doing but remove the middle-man (Dropbox servers)?

• How to make Notepad++ take over from the standard notepad.exe

  - by Nick

  I could do this easily with TextPad, then I got irritated with Textpad once I'd played with Notepad++. Now that I've removed Textpad: I want Notepad++ to take over the right-click Edit option in Explorer, and I want Notepad++ to come up when I type notepad in the command prompt. I know that Notepad++ has a shell extension that allows one to do right-click Edit in Notepad++. But my old right-click Edit link remains, and I keep finding myself clicking on it, only to be rewarded with an error.

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• Setting Timeouts: SQL Server 2008/IIS 7.5

  - by Julie

  We have recently migrated from a Win 2003/SQL Server 2000 system to Win 2008 64 bit R2, SQL Server 2008 R2. Our websites are in classic asp, and this can't be changed to another scripting language at this time. On the old server, if I got stuck in some kind of endless loop, the page would throw an error. On the new server, I have a page that has some sort of looping problem, that even though the SQL SP is called only once (and runs fine run as a query on the server) it pegs SQL server and therefore locks all of our websites. I'll get my code figured out, no biggie. But I need to make sure the server times out when this happens. (The page I'm working on runs fine with certain instances of the query, and locks with others using a different query variable. I can't have something like that sneak up on me on a page I haven't touched for three years.) I can't figure out how an SP that runs once on the server, from an ASP page, is tying up SQL server this way. It's obviously some sort of a timeout issue, but I can't figure out where/which timeout values to change. I actually have to remote desktop to the server and kill the process in SQL server. I'm afraid I'm a generalist, and server management is not my thing, even though it's my responsibility, so I am almost certain to have questions about any answer that I receive. How can I track this down? What settings do I need to change? More info: It's not SQL Server On our test site, I created an ASP file that just did an endless loop (do while 1=1) and had the same problem - the other websites wouldn't load - without SQL server being involved. So I think the reason the process was hanging is that the page wasn't timing out as it should, and so the connection to SQL was never closed. Killing the process in SQL server would reset the page somehow. For my intentional endless loop, I had to refresh the app pool to get rid of it. This points more to either IIS or the ASP settings. The ASP timeouts are set to whatever the default were when the server was first loaded. I still can't figure out why one file is locking up all websites, though. Again, that didn't happen on the old server.

• Setting up Splunk/IronPort WSA

  - by Ciddan

  I recently stumbled across Splunk 4 (by way of an advert on this very site...) and found that it had an "App" that's designed to work with Cisco IronPort WebSecurity and E-Mail Appliances! That's really awesome, because good IronPort reporting is something our IT-dept. is looking for. Anyways - I'm totally lost on how to configure this thing. I've googled like a mad-man to find a guide or such like - but I haven't found anything. Has anyone here set up IP / Splunk? Any tips/pointers?

• Bonjour/DNS Service Discovery queries

  - by senloe

  I'm trying to implement dns service discovery in my application (no, I'm not asking for a programmatic answer). What I believe is one of my big pain points is generating the query. I know I need to send out a multicast broadcast on port 5353 and want to look for devices of type _ipp._tcp and _print._tcp, but I don't know what the question section needs to look like. For example, in SSDP I sent out a query that looks like the following: "M-SEARCH * HTTP/1.1\r\n" "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" "ST: urn:schemas-upnp-org:device:Printer:1\r\n" "MX: 5000\r\n\r\n" From what I know about a DNS query I need to send something like: "_ipp.tcp,all,all" but I know there needs to be more. Any pointers to documentation, etc would be greatly appreciated! update rfc1035 appears to contain promising information re the message structure.

• Wireless networking on Gnome on Ubuntu 9 / 10

  - by WaveyDavey

  So here's my problem: I have some netbooks (ASUS eee, and ACER Aspire Ones) that I've been tasked to set up as kiosk machines, locked up tight for normal users. I am a command-line, server man, so this gnome malarkey is all a bit new to me. I found a lovely 9.04 kiosk livecd that installs and runs exactly as I want it to, but I can't get the wireless working. So I dropped on a full 10.4 distro, and wireless works straight out of the box (so hardware is good) - all I needed to do was right-click on the network connection icon, enter my SSID and password (WPA/WPA2) and away it went, perfect. Further investigation on 10.4 distro shows that /etc/networking/interfaces is virtually empty (just auto lo iface lo inet loopback in it), even after I have set up the wireless thru the gnome taskbar applet (is that the right word?). So where does gnome / ubuntu store the network settings to bring the blasted wireless connection up, and what do I need to do on the kiosk version to get wireless running?

• Keep IIS7 Failed Request Tracing as a sysadmin only diagnostic tool?

  - by Kev

  I'm giving some of our customers the ability to manage their sites via IIS Feature Delegation and IIS Manager for Remote Administration. One feature I'm unsure about permitting access to is Failed Request Tracing for the following reasons: Customers will forget to turn it off The server will be taking a performance hit (especially if 500 sites all have it turned on) The server will become littered with old FRT's The potential to leak sensitive information about how the server is configured thus providing useful information to would-be intruders. Should we just keep this as a troubleshooting tool for our own admins?
