  • Determining Namespaces Not in the ACPI Spec

    - by Eddie B
    I am trying to determine how it may be possible to find documentation for namespaces that are not documented in the ACPI spec. I have an Asus uEFI BIOS v(3202) and I'm receiving kernel messages stating AE Namespace lookup failures for DSSP. This is referring to a namespace that is not in the ACPI spec. I'm presuming that this is vendor specific and refers to a Digital Sensor Signal Processor. That is only a presumption. In an effort to correct ACPI errors I have dumped my DSDT using acpidump and then decompiled it using iASL. Yet to fix the error I need to know the spec on the namespace. How can I get access to the BIOS documentation that isn't part of the ACPI spec?

  • "IP May Be Forged" - Sendmail Warning

    - by Mikey B
    CentOS 5.x | SendMail 8 Can I get clarification on what exactly the warning "IP may be forged" means and what conditions cause it? I recently configured SendMail to relay email from my exchange server and it's showing that warning in the logs. The messages get delivered fine but I don't like the warnings. I originally thought that there was an inconsistency between the servername used in the EHLO statement from Exchange and the respective PTR record for the source IP for Exchange. But upon examining a packet capture, I see exchange using "EHLO domain.com" and that the source IP has a PTR of "domain.com". Maybe sendmail doesn't like that the greeting only has the domain? -M

  • Linux Centos - Mail Deamon Preferences

    - by Iestyn
    I keep getting emails from root into my inbox, I get about 30 a day which is annoying as hell and I'm wondering how I can filter these emails down so that I only receive the essential emails. I don't want to have an email every single time I log in via SSH, but when you 30-40 a day sometimes it can get pretty annoying. Is there a section in cPanel or WHM where I can tick or un-tick a section to choose which emails I wish to receive? I also get mail deamon bounce email messages which I'd also like to disable. I've looked and looked, but I think I'm either overlooking something simple or I'm looking in the wrong place.

  • Systemd can't start script?

    - by TokyoMEWS
    I have a BASH-script I want to run on start up. My system is running systemd so I created a .service file with whith what I think is the neccessary information: [Unit] Description=My Script After=network.target [Service] ExecStart=/home/myscript.sh [Install] WantedBy=multi-user.target I used systemctl enable to 'register' it an rebooted. On boot I was told my script would be executed, but I could neither see any of the messages ECHO should display on screen nor did it write something to a file, according to what I had written in the script. Additionally, It does not start the application it's supposed to start. Systemctl status tells me that the script has run and exited successfully. Still, the script has no effect. If I run the script from a shell it works perfectly fine. Do any of you know what could be my problem?

  • How to turn archiving off in thunderbird 3.1?

    - by chobo2
    Hi I don't really understand what the archiving really does in thunderbird but it is kinda annoying. Like if I get a email and read it. It will turn to read in my inbox, but will show up as unread in my archives section. So the next time I get an email the thunderbird notification will popup and show that I have 1 new email but will show all those unread one in my archive. So even though I read all of the emails in my inbox the next time I get an email I get a popup notification of 6 messages when it should be 1 since 5 of those where in the archive and marked as unread. Anyone know how to stop this?

  • Can I ping via an arbitrary interface of a DD-WRT system?

    - by bytebuster
    There's a Linksys WRT54GL router with DD-WRT firmware (v23SP2). The network has a simple dual-WAN configuration (standby mode, switching by a script): ~ # ip route 192.168.3.0/24 dev br0 proto kernel scope link src 192.168.3.1 192.168.2.0/24 dev vlan2 proto kernel scope link src 192.168.2.2 192.168.1.0/24 dev vlan1 proto kernel scope link src 192.168.1.67 127.0.0.0/8 dev lo scope link default via 192.168.2.1 dev vlan2 I'm trying to ping a certain server arbitrary via vlan1 or vlan2. What I tried, as suggested here: ping -I vlan2 <address> ping 192.168.2.1 <address> In both cases ping simply exits with no error messages. Also, ping ignores many other parameters, again, by exiting silently. I failed to find any references that DD-WRT has a limited version of ping whatsoever. I also don't think it can be a permissions issue as mentioned here since the only user with DD-WRT is root. What's wrong?

  • Using MRTG's threshold feature to execute a php script

    - by Dan Fried
    I've set up mrtg using the online manual and the only online tutorial I found on the subject of thresholds, and the threshold just isn't firing. In my mrtg.cfg file, the relevant lines are ThreshDir: /path/to/mrtg/thresh ThreshMaxI[performance]: 1 ThreshMaxO[performance]: 1 ThreshProgI[performance]: /path/to/mrtg/scripts/alert.php ThreshProgO[performance]: /path/to/mrtg/scripts/alert.php The paths are right, because if I enter the paths wrong I get an error on executing mrtg. websitePerformance checks how long it takes to download the homepage, in milliseconds, so it should be exceeding the max every time. Alert.php is working fine when invoked directly from the shell, and when I point to a nonexistent script it tells me the script is not executable. No error messages are being generated, that I can find. The thresh directory is always empty. Why isn't the threshold being triggered by results that are greater than 1? Anyone have any suggestions?

  • Screencasting with explanation boxes

    - by Bakhtiyor
    I wanted to make a video demonstration of one software. I wanted to use text description instead of using voice description, a simple example of what I've explained could be this short screencasting, where author uses short text messages instead of explaining it with his own voice. Could you recommend any free software for doing such a screencasting please? Would be better if it works in Ubuntu or if it is a web application. UPDATE I have found out Wink which could add explanations boxes as I said. Now the problem is that it doesn't support Linux 64bit, has only 32bit. Any other app like Wink for 64bit Linux?

  • Disconnected from WiFi, Windows claims otherwise [closed]

    - by Manu
    I'm connected via wifi to my ISP's router/modem. While Windows says that I'm always connected, I keep getting messages from Netgear Genie that I've lost contact to the Internet, and I cannot access webpages until it comes back. There are two other computers in the house, one connected to the router via ethernet, the other via wifi, both seem to have no such problems. I've wondered if Netgear genie itself was the problem, but I am regularly disconnected even if I uninstall it. And I'd rather have it since it accurently tells me if I'm connected or not. Why does windows says I'm online if I can't access any online game, or website ? I've removed the connection, recreated it, I've even copied the settings to a usb key from the computer that has wifi access. Is there a tool that can tell me which program, if any, is disconecting me ?

  • Sendmail.mc: alias all incoming e-mails to one account

    - by Angus
    I need to alias all mail coming from another SMTP server to this one account "myinbox". The system in question is to receive all e-mail on the domain, if that's any help. http://william.shallum.net/random-notes/sendmailredirectallmailfordevelopment is a template for the beginning of a solution, but that routes everything (including outgoing and internal mail) to that one account, and trying to understand how these R rules work is making my head spin. I think the answer is in sendmail.mc rather than any Procmail configuration. So I think what I generally don't want the filter to do is: Interfere w/any outgoing e-mail Interfere w/any internal e-mail Sometimes some cron job causes "root" to mail to "root". I don't want these to go to myinbox. Cause infinite loops Who does? Bounce messages and any DSNs come to mind. I'm running Sendmail 8.13.1 and Procmail 3.22.

  • Accessing localhost via IIS 7.5 on Windows 7 very slow

    - by Ian Devlin
    (I've asked this over on stackoverflow already, but thought I'd ask here as well) I'm currently running an ASP.NET application on IIS 7.5 on Windows 7. When I access this application on Internet Explorer (either 6, 7 or 8) it is incredible slow and often fails to load at all. There are messages at the bottom saying: Waiting for http://localhost/....... or sometimes waiting for about:blank (I've read that this can be a virus, but I've run all the usual checks and it's not). constantly, but it returns with the usual: "Internet Explorer cannot display the webpage" I've also tried this by using 127.0.0.1 and the machine name, with the same results. I've tried the same application on the latest Firefox, Safari, Chrome and Opera and they all work fine. I've also installed the same application on a Windows Server 2003 machine, and it all works fine via Internet Explorer. I've also turned off the IPv6 setting on the LAN connection. Soes anyone have any ideas why this doesn't work with Internet Explorer and yet does with other browsers?

  • Solaris TCP/IP performance tuning

    - by Andy Faibishenko
    I am trying to tune a high message traffic system running on Solaris. The architecture is a large number (600) of clients which connect via TCP to a big Solaris server and then send/receive relatively small messages (.5 to 1K payload) at high rates. The goal is to minimize the latency of each message processed. I suspect that the TCP stack of the server is getting overwhelmed by all the traffic. What are some commands/metrics that I can use to confirm this, and in case this is true, what is the best way to alleviate this bottleneck? PS I posted this on StackOverflow originally. One person suggested snoop and dtrace. dtrace seems pretty general - are there any additional pointers on how to use it to diagnose TCP issues?

  • How do I find out what a Spam Custom Rule is?

    - by SoaperGEM
    We use a Barracuda Spam Filter at work, and we also provide a mass emailing program to some of clients that send out newsletters. Lately one of them's been composing his latest company newsletter and has been trying to send preview messages to himself, but they've actually been quarantined by Barracuda as potential spam, even though they aren't. I can see the breakdown of the spam scoring headers in Barracuda, but I'm not sure what certain rules mean. Here's the breakdown: pts rule name description ---- ---------------------- -------------------------------------------------- 0.00 FUZZY_CPILL BODY: Attempt to obfuscate words in spam 2.21 HTML_IMAGE_ONLY_24 BODY: HTML: images with 2000-2400 bytes of words 0.00 HTML_MESSAGE BODY: HTML included in message 0.50 BSF_SC0_SA_TO_FROM_ADDR_MATCH Sender Address Matches Recipient Address 1.00 BSF_SC0_SA392f Custom Rule SA392f What is "Custom Rule SA392f"? Where do I find descriptions of these custom rules? And what does "images with 2000-2400 bytes of words" mean? Is that referring to the file size of the image, or something about the attributes on the <img> tag?

  • Will Hotmail DELIVER to spam-friendly ISP?

    - by Oddthinking
    I have a user who is using Hotmail to communicate with one of our suppliers. Recently, Hotmail started bouncing emails to that address (while other ISPs are working fine.) Hotmail bounce messages contain very little details. Investigating, I found that the supplier's ISP has appeared on a blacklist of ISPs who do not do enough to prevent spamming from their users. (Note: Neither my user nor the supplier are mass-mailing.) In the circumstances, I can understand Hotmail declining to accept emails from the host, or accepting them but being quick to mark them as spam. However, I am surprised that they might refuse delivery. Does this sound plausible to you, or am I barking up the wrong tree?

  • Eventlog entry for allowed connection in Windows Firewall

    - by Jaap
    I was seeing a lot of entries in the eventlog: The Windows Filtering Platform has permitted a connection. Application Information: Process ID: 4 Application Name: System Network Information: Direction: Inbound Source Address: 10.xxx.xxx.xxx Source Port: 80 Destination Address: 10.xxx.xxx.xxx Destination Port: 31773 Protocol: 6 Filter Information: Filter Run-Time ID: 67903 Layer Name: Receive/Accept Layer Run-Time ID: 44 We have a loadbalancer which checks every second to see if the application is still running (a health check). The logs contain large amounts of this kind of entries, which makes the Event Viewer slow and it's difficult to find the more interesting logs. How do I make sure these messages don't end up in the event logs?

  • Why can't mplayer/libdvdcss/whatever play my DVDs?

    - by che
    To put it bluntly, mplayer is unable to correctly play video DVDs. It seems to correctly find the title and everything, but the picture is broken or not displayed at all, with messages like: a52: CRC check failed! a52: error at resampling [mpeg1video @ 0xa8d840]sequence header damaged [mpeg1video @ 0xa8d840]Missing picture start code Now, this all is on amd64 Gentoo Linux system. I believe the problem is not in mplayer itself, since the playback also breaks in VLC or when i copy the VOBs via vobcopy and try to play them afterwards. I use libdvdcss-1.2.10 and libdvdread-4.1.3_p1168 (current stable in Gentoo), and tried previous versions of both libs, but it didn't change a thing. The DVDs I have tried play fine in regular DVD player or on a Windows laptop. I remember the playback used to work about a year ago and I don't know what to try next. Any hints would be welcome.

  • how to copy sql server database on same server

    - by Sam
    I've got a SQL Server 2008 and want to make a copy of a database so I've got a 2nd Version of the database for testing on the same server. The database copy wizard is not able to copy the database, it always sends funny error Messages about missing objects (using SMO copy). When I try to make a backup and restore it under a different database name it still keeps the file names of the original database and overrides this (crashing the original database). So how do I copy a SQL database? Shutdown SQL Server, copy the physical files and attach them? Maybe a command line tool for database copy? Shouldn't there be an easy way to make a copy?

  • Why are default spamassassin rules not being applied to emails we generate?

    - by Chance
    My company uses a standalone spam-assassin install to test marketing emails, however, mail originating from us does not seem to run the full gamut of test. For example, Spam assassin has a default rule that flags messages that contain the phrase Dear [Something], and it properly flags spam that I feed it.It does not, however, apply that same rule to in house email I send it. Is it possible that spam assassin has white-listed us somehow, perhaps because the mail originates in the same domain as the server or receiver? I believe most of the recent spamassassin questions have been mine, so thanks for bearing with me as I figure this out! Chance EDIT Details on our SA setup: We are piping the emails into the CL with spamc -R < test_email.eml Identical results testing as root or a user, no user_prefs file

  • How can I see logs in a server after a kernel panic hang?

    - by Low Kian Seong
    I am running a production gentoo Linux machine, and recently there was a situation where the server hung in my co-located premises and when I got there I noticed that the server was hung on what appeared to be a kernel panic hang. I rebooted the machine with a hard reboot and was disappointed to find out that I could not find a shred of evidence anywhere on why the machine hung. Is it true that when I do a hard reboot the messages itself will get lost or is there a setting I can do somewhere say in syslog-ng or maybe in sysctl to at least preserve the error log so that I can prevent such mishaps from happening in the future ? I am running a 2.6.x kernel by the way. Thanks in advance.

  • How to keep Varnish cached populate after backend down for an extended period?

    - by Nicholas Tolley Cottrell
    We have Varnish 3.0.2 running on Amazon's Linux and it works great. We have a ttl of 48 hours for most content pages and much longer for images, PDFs etc. This weekend we've taken the backend down for some maintenance, so I upped the ttl to 5 days earlier in the week. I had assumed that anything in cache would continue to be served for up to 5 days, but much to our disappointment we checked varnishstat this morning and the cache was almost completely empty and varnish was serving "page not found" messages. I know that this is not what Varnish is designed to do, but why would it reset its cache when the backend is down? And how can I prevent it for next time?

  • Linux + IPTables + NAT = some http hosts unreachable.

    - by Daniel
    Hi. I've set up dead simple NAT: iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o ppp0 -j MASQUERADE Everything works almost ok. Almost. The problem I've expirienced is some hosts are not reachable by NAT clients, i.e. there's http://code.jquery.com/jquery-1.4.2.min.js - I can download it from server, but in case of NAT client download stalls on connection stage. I thought its FFs fault, but wget has the same issue. I didn't find any logs/messages that can shed some light on this situtation. Any ideas what's going on? Maybe some tricky thing in sysclt is causing this? P.S. 3/3 client boxes are expiriencing this issue. This is definitely server trouble.

  • Incorrect "from" account used when accepting Outlook meeting requests

    - by Greg
    I am using Outlook 2013 and I have multiple accounts configured: AccountA (IMAP) - default account AccountB (Exchange) (There are others but I don't think it's directly relevant) I have been receiving Outlook meeting requests via AccountB and duly accepting them. All of my meetings, whether recorded manually or via meeting requests are saved in the calendar for AccountA (this works fine). I have discovered today that even though meeting requests are arriving via AccountB, the accept/decline messages that Outlook generates on my behalf (when I click the accept/decline button) are addressed from AccountA. I don't believe that I have any control over the address used to reply. This seems non-intuitive at best. I understand that the underlying calendar is in AccountA, but in every other scenario the "From" address in a reply to a message defaults to the account it was sent to. Can I change this behaviour so that it works as I expect?

  • What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?

    - by Forgiver
    I have an external hard drive that is connected to my computer (Windows 7 Ultimate 64 bit) via a USB port. BitLocker has been activated on the hard drive to protect the data. Yesterday I started downloading a huge data from the internet but now it failed to complete because of CRC error. I tried to repair it with chkdsk f:/r where f is the drive letter of that hard drive. There are many messages reporting "unreadable" as follows: What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?
