  • Routing multiple static IPs from ISP at the cable modem?

    - by Jakobud
    I'm taking over IT responsibilities for a previous IT guy. We have a 50mb cable modem connection from Comcast along with 5 static IP addresses: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 We are in the process of replacing our firewall machine. Currently the firewall box is the only thing connected to the cable modem. However the cable modem has multiple ethernet ports on it, similarly to a router. I have assembled a new firewall machine and its time to start testing and configuring it. So that means that I also need it plugged into the cable modem (remember it has multiple ethernet ports on it). So now with multiple computer plugged into the cable modem, how does the cable modem know where to route the traffic? If some request on the internet is made to XXX.XXX.XXX.181, which goes to our cable modem, how does the cable modem know which connected computer that traffic is supposed to be sent? Looking at the web interface for the cable modem, there doesn't seem to be anything special setup on it with regards to routing or NATing IP addresses. Is that because when there is only one computer connected to the modem, all traffic is sent to it by default? Now that I am going to (temporarily) have multiple computers plugged into the cable modem, do I need to specify routing or NAT rules on the modem itself? I am going to speak to Comcast about this next, but I figured I'd ask here first just so I can get a better grasp on how this type of thing generally plays out.

  • SMB access from XP to Windows 2008 R2

    - by Pablo
    Here's the thing... I have a very slow file copy performance from Windows XP clients to Windows 2008R2 servers. Here are the facts: Windows XP to Windows 2K3: Fast Windows XP to Windows 2K8: Very Slow Windows 7 to Windows (any): Fast Despite the fact that the obvious solution would be to upgrade to Windows 7, well, we have 900 desktops so it's not an option in the short time. I have tried everything: Disabling SMB2.0, disabling security signatures, changing the TCP Window size, disabling the W2K8 auto tuning, upgraded the drivers, etc. We eliminated the network; both the server and the client are connected to the same core switch (no hops, no routers, same VLAN). Upon monitoring the network with a packet capture utility, we see that the SMB packets being exchanged between the W2K8 and the XP machines are very small packets (256 bytes); despite the fact that the MTUs are properly set (1500) and there is no fragmentation whatsoever. In fact, those SMB packets show, on the IP datagram, that the window is 65535 or close. The same trace, made using the same application but instead of using a W2K8 share uses a Windows XP share (and that goes FAST) shows SMB packets of 4096 bytes. I can post the traces if necessary. So, why does XP-W2K8 negotiation arrange for 24-bytes SMB payload, whereas the XP-XP negotiation arranges for 4096 SMB packets? Any ideas? I am running short of those...

  • Mystery undeletable file

    - by Hugh Allen
    I can't delete C:\Config.Msi\75ce84f.rbf. it's not readonly, system or hidden it's not in use by another process (according to Process Explorer) the NT security permissions aren't the problem either - I am the owner and have Full Control ; as a double-check, the Effective Permissions tab shows that I have permission to delete. Yet trying to delete the file gives "Access is Denied" from both Explorer and cmd. I can however rename it or move it to another folder on the same drive. I can also read it and Virustotal says it's clean which is what I would expect (it's just a Windows Installer temp file - a copy of some DLL I think). The relevant line from Process Monitor is: 6:52:14.3726983 PM 112 Explorer.EXE SetDispositionInformationFile C:\Config.Msi\75ce84f.rbf CANNOT DELETE Delete: True Write 1232 Background: I'm using XP SP2. I recently repaired my Adobe Reader installation to make it the default browser plugin again instead of Foxit. (there seems to be no UI to do it otherwise?) So the installer did its thing and then asked to reboot. As is my habit when rebooting is inconvenient I declined the offer and ran pendmoves to find out what files the installer had scheduled to move / delete. It wanted to delete two files with .rbf extension (rollback files) located in C:\Config.msi\. (this applies to both even though I've been speaking about one). So I tried to delete them manually and couldn't. Does anyone have any ideas what could be preventing deletion? (and I don't think it's malware even though I'm not running AV at the moment)

  • AWS lighttpd: Sending a copy of requests to test.

    - by Martin
    I have a load balanced service on AWS. So the ELB evenly distributes the load across my servers. Each server is running lighttpd that does logging and forwards the requests to my service (on the same machine). I have written a new version of the service. It is installed and running on an EC2 machine test1 (basically a mirror of our current server but the new service running instead of the original) and I have done some preliminary tests that look good. But what I would like to do is mirror a fraction of incoming traffic to the new version of the service so I can do some comparisons between an original version and the new version based on real traffic. Thus I was thinking I could modify one box behind the ELB to duplicate its traffic to the test1. I was thinking I could modify the configuration of lighttpd so that each request is mirrored/duplicated. i.e. the original service keeps responding as before but a mirror request is sent to test1 but the reply is just dropped). Unfortunately I have not been able to work this out. Any ideas on how I could mirror the requests from one box to itself and test1. Or any other ideas for testing.

  • Start Menu Shortcuts resisting reorganisation

    - by seusr
    Running Win7. The Start Menu was getting too big, so I've navigated to C:\ProgramData\Microsoft\Windows\Start Menu\Programs and created some sub-folders in various categories [image editors, system utilities, media players, security for example] in which to group the shortcuts. Having created the group folders, I've dragged and dropped the Start Menu shortcuts into them. However it seems all Start Menu shortcuts are not alike. Some programs, their shortcut folders having been moved from the Start Menu, spawn NEW [but empty] folders bearing their company names in the top level of the Start Menu eg AVICodec Some programs don't have Start Menu shortcut folders that can be seen in WinExplorer [or equiv] at all, even though they turn up under the Start Menu itself. It seems these can be moved where they are visible i.e. in the Start - All Programs by dragging and dropping not just onto the desired folder but by hovering to expand the desired folder and then dropping between other shortcuts there. Eg Daum, Format Factory That's not such a problem, but why it's happening is a mystery. What's going on, and how to make these shortcuts behave normally or otherwise control them properly?

  • How to use Windows mini-dump files?

    - by ekaj
    I have a Mini-ITX Intel DH61AG mobo w/ an Intel i3 processor and 8GB of 1600MHz DDR3 RAM. Anyways, this computer has been crashing kind of frequently. It is not an OS problem, as I have used Ubuntu (and had kernel panics), Windows 7, and Windows 8 (BSODs aren't going to keep me from tinkering =p) Anyways, each of these OSes have had problems, so I ran a HDD check, and I know it is not a heat issue because I tested the processor for a few days when I first put the computer together. When I ran memtest86+, however, I got an error - so I did individual testing, and both chips came back good, did a really intense test with both of them again (took half a day), and no errors. So, I still think the problem could be RAM, but I am not sure - I tested it pretty extensively (might let it run all night again tonight)... which brings me to my point. Could someone explain to me (in simple terms if possible) how to READ the minidump files of Windows computers? I've tried before with a guide I found online, but failed miserably (can't remember guide, either =/). I'm fine with installing the software, I will probably need it sometime in the future as well. I have seen a few other posts on SU that just ask people to post minidump logs, but I feel as if that is too localized. Would someone be able to explain this? Note: If someone knows how to do this, but doesn't want to explain and is still willing to help me, this is the link for the minidump file =p Make sure to click

  • RDP problem with Vista and Windows 7 destination

    - by MadBison
    I use a server a home to host a bunch of concurrently running Hyper-V VM's with different OS's and software for testing. I have Vista on the laptop, all latest SP's and patches. The server is Server 2008 R2, fully patched. The guests are a mix of XP, Vista, Server 2008 and Windows 7. If I connect to the Win XP or Server 2008 guest using RDP, it is always good. Very quick, no speed issues. If I connect to the Vista or Win 7 guests, the response time is so slow it is unusable. Usually 6 or 8 seconds, and at times it is to long to measure! This happens from both the laptop running Vista, and the server running Server 2008 R2. Does anyone know what the issue is with RDP on Vista and Windows 7 destinations? I did read this: http://blog.tmcnet.com/blog/tom-keating/microsoft/remote-desktop-slow-problem-solved.asp and that is not the problem I have applied that change to all PC's.

  • HP Procurve Issue Passing Multiple VLANs over a link

    - by MichaelRwat
    Just to start off with I am a Cisco guy that got placed into an HP project. Basic topology overview from outside in: ASA 5505 with two Ethernet connections to a 2910-24 port switch. This switch is then (Cisco Trunking) to a 2626 switch passing vlan (1 untagged and 100 tagged)between them. I created SVI's on each of the switches for both VLAN's for testing purposes. I can not get vlan 100 to pass across this link. I also have trunks configured to AP's off of the switch and can not ping the vlan 100 BVI on the AP's but can reach the vlan 1 BVI. Port 25 on Access layer (2626) connects (trunks) with port A1 of 2610. STP is not running at all on any switch (this is not my network I can't change this nor did I design this) Distribution Sw: MP1-0# show run ip default-gateway 10.100.100.100 vlan 1 name "DATA" untagged 1-22,24-A1,B1 ip address 10.100.100.6 255.255.255.0 no untagged 23 exit vlan 100 name "GUEST" untagged 23 tagged 24-A1 ip address 10.100.102.6 255.255.255.0 exit Access Sw: ip default-gateway 10.100.100.100 vlan 1 name "DEFAULT_VLAN" untagged 1-26 ip address 10.100.100.5 255.255.255.0 exit vlan 100 name "GUEST" ip address 10.100.102.5 255.255.255.0 tagged 15,25 exitt From the ASA I can ping the vlan 100 address of the 2610 but not the 2626 (10.100.102.6)[Not passing the "trunk"] If I plug into an access port vlan 100 of the 2626 I can ping the SVI for vlan 100 as intended. I can not ping across the "trunk" over vlan 100 but I can across vlan 1. There may be something obvious I'm missing but please review my configuration and thank you for the assistance.

  • Random Hard Freeze of Windows 7 (is Kaspersky to be blamed for this?)

    - by Christian Ivicevic
    The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck. Using Ubuntu this does not happen, so I think it is just a matter of driver issues or a Windows 7 bug. Furthermore I am really suspicious about Kaspersky (Internet Security 11) and so I let it perform a complete virus scan while no other app is running. At about 50% it happened again and I needed to restart the computer by holding the power button the bad way... A really weird thing is that playing Skyrim this happened once, however music playback did not stop. Only the framerate dropped to 0 and sometimes for a few seconds I am able to move. Therefore I am really confused as furthermore no bluescreen pops up. Memtest told me that everything seems to be alright... Can anyone explain me which data you need about my hardware and software (and which tools tools to use to gather the informatik) to be able to provide any help on my problem?

  • syslog-ng and nging logs to mysql

    - by Katafalkas
    So couple of days ago I asked how to log php and nginx logs to centralized MySQL database, and m0ntassar gave a perfect answer :) cheer ! The problem I am facing now is that I can not seem to get it working. syslog-ng version: # syslog-ng --version syslog-ng 3.2.5 This is my nginx log format: log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; syslog-ng source: source nginx { file( "/var/log/nginx/tg-test-3.access.log" follow_freq(1) flags(no-parse) ); }; syslog-ng destination: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("superpasswd") database("syslog") table("nginx") columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_ referer","http_user_agent","http_x_forwarded_for") values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR")); }; MySQL table for testing purposes: CREATE TABLE `nginx` ( `remote_addr` varchar(100) DEFAULT NULL, `remote_user` varchar(100) DEFAULT NULL, `time` varchar(100) DEFAULT NULL, `request` varchar(100) DEFAULT NULL, `status` varchar(100) DEFAULT NULL, `body_bytes_sent` varchar(100) DEFAULT NULL, `http_referer` varchar(100) DEFAULT NULL, `http_user_agent` varchar(100) DEFAULT NULL, `http_x_forwarded_for` varchar(100) DEFAULT NULL, `time_local` text, `datetime` text, `host` text, `program` text, `pid` text, `message` text ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Now first thing that goes wrong is when I restart syslog-ng: # /etc/init.d/syslog-ng restart Stopping syslog-ng: [ OK ] Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future; [ OK ] I have tried creating a file destination and it all works fine, and then I have tried replacing my destination with: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("kosmodromas") database("syslog") table("nginx") columns("datetime", "host", "program", "pid", "message") values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY") indexes("datetime", "host", "program", "pid", "message")); }; Which did work and it was writing stuff to mysql, The problem is that I want to write stuff to in exact format as nginx log format is. I assume that I am missing something really simple or I need to do some parsing between source and destination. Any help will be much appreciated :)

  • EEE PC Keyboard malfunctioning - Ctrl key "sticks" after 10 seconds

    - by DWilliams
    I was given a EEE PC belonging to a friend of a friend to fix. The keyboard did not appear to work at all. I spent a while testing out various things, blowing the keyboard out, checking for damage, and so on. Nothing appeared to be physically wrong. At first I noticed that the keyboard appeared to work just fine for 10 seconds (on average, sometimes more sometimes less) after being powered on. It had been restored to the factory default xandros installation with no user set up, so I couldn't get in to mess with things since I couldn't type to make a user. I made an ubuntu live USB to boot it from, and managed to get the boot order changed to boot from USB in the ~10 seconds of working keyboard I had (I don't think I've ever had to rush around BIOS menus that quickly). After I got Ubuntu up on it, I played around a bit more and determined that apparently the ctrl key is stuck down (not literally, but it's on all the time). If I open gedit, pressing the "o" key brings the open dialog, "s" opens the save dialog, and all other behaviour you would expect to see if you were holding down the control key. The only exception that I noticed is the "9" and "0" keys. They function normally. Figuring that out I made a xandros user with a name/password consisting of 9's and 0's. I couldn't find any options in Xandros that could potentially be helpful. I'm not familiar with EEE PCs. Is it safe to assume that the keyboard is simply dead or could there be another problem? I don't want to purchase another keyboard for him if that isn't going to fix the problem. The netbook doesn't show any obvious signs of damage but the owner is a biker and very often has it with him on the road so it's been subjected to a good bit of vibration.

  • Browser sends http request with RANGE

    - by nute
    I have a local testing environment in a Fedora virtual machine. Strangely, resources (css and js files) don't seem to work. Looking at Firebug, I see that the browser sends the HTTP request with "Range bytes=0-". The server responds with either an empty 200OK or an empty 206 Partial Content. Here is an example: Response Headers Date Mon, 23 Nov 2009 23:33:26 GMT Server Apache/2.2.13 (Fedora) Last-Modified Thu, 19 Nov 2009 22:58:55 GMT Etag "18-3aec-478c14dbee138" Accept-Ranges bytes Content-Length 15084 Content-Range bytes 0-15083/15084 Connection close Content-Type text/css Request Headers Host fedora.test User-Agent Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.5) Gecko/20091105 Fedora/3.5.5-1.fc11 Firefox/3.5.5 Accept text/css,*/*;q=0.1 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 300 Connection keep-alive Referer http://fedora.test/pictures/ Cookie __utma=26341546.1613992749.1258504422.1258569125.1258752550.4; __utmz=26341546.1258504422.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); PHPSESSID=tqf8jfmc77qihe97rl4tmhq685 Range bytes=0- If-Range "18-3aec-478c14dbee138" I don't know if the browser is sending the wrong request, or if it's the server that is doing this. Request made to the outside (such as google analytics) are working fine. This is running in Fedora 11 in VirtualBox. Apache. PHP. The files are being served through the "shared folders" feature of VirtualBox (could it be related?). No error logs could help me.

  • try to attach to a database file but can't browse folder which contains the file

    - by Chadworthington
    I am trying to attach to database file (*.mdf, *.ldf) that I placed in the same folder as all my other SQL Server databases. I begin the attach by attempting to browse to the folder which contains the db files as well as all of my active database files. I select "attach Database" and click the "Add" button to add a database to the list of databases to attach to. When I do so, I get this error: TITLE: Locate Database Files - BESI-CHAD ------------------------------ D:\SQLdata\MSSQL10_50.SQLBESI\MSSQL\DATA Cannot access the specified path or file on the server.

  • Apache directory structure with multiple hosted languages.

    - by anomareh
    I just got a new work machine up and running and I'm trying to decide on how to set everything up directory wise. I've done some digging around and really haven't been able to find anything conclusive. I know it's a question with a variety of answers but I'm hoping there's some sort of general guidelines or best practices to go by. With that said, here are a few things specific to my situation. I will be doing actual development and testing on the same machine as the server. It is a single user machine in the sense that I will be the only one working on the machine. There will be multiple hosted languages, specifically PHP and RoR while possibly expanding later. I'd like the setup to translate well to a production environment. With those 3 things in mind there are a couple of things I've had in the back of mind. Seeing as it's a single user machine I haven't been able to decide whether or not I should be working on things out of my home directory or if they should be located outside of it. I'm feeling that outside of a user directory would be better as it would translate better to a production environment, but I'm also not sure if that will come with any permission annoyances or concerns seeing as I'll be working on the same machine. Hosting multiple languages seems like it may be a bit quirky. With PHP I've found you're generally just dumping the project somewhere in the document root where as something like a Rails app you have the entire project and you only want the public directory in the document root. Thanks for any insight, opinion, or just personal preference from experience anyone can offer.

  • Is On-The-Fly string replacement possible using GreaseMonkey and Firefox

    - by Gary M. Mugford
    I have looked for means to stop Brightcove videos from autostarting in Firefox and have come to the conclusion it isn't possible without external programming via something like Grease Monkey. However, I'm not proficient in javascript let alone GM. So I thought I'd ask here first whether what I want to do is feasible, or whether it's a fool's errand. What I want to accomplish is have a site specific script executed to replace a string value on the run in that site's code. Specifically, what I am looking for is something GM-style that would do this: if site_domain = 'www.SiteWithAutoPlayVideos.com' then replace_all('<param name="autoStart" value="true" />', '<param name="autoStart" value="false" />'); Having looked through Super User for anything GreaseMonkey that might relate, I see notices that the sandbox GM executes scripts in has to remain separate for security reasons. So, I suspect I might be in for disappointment. BUT if it is accomplishable and somebody here can confirm it, then I will do my best to struggle through the learning curve and get this noisome little problem put to rest. Yes, I have tried Flash Block and FlashDisable in order to attack this issue with no avail. Thanks in advance for your time.

  • Task Scheduler Crashing MMC

    - by Valrok
    I've been getting errors whenever I try to run the task scheduler for Windows 2008 R2. Each time that I've tried running it, the task scheduler will crash and report the following: Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: mmc.exe Problem Signature 02: 6.1.7600.16385 Problem Signature 03: 4a5bc808 Problem Signature 04: System.Windows.Forms Problem Signature 05: 2.0.0.0 Problem Signature 06: 50c29e85 Problem Signature 07: 151f Problem Signature 08: 18 Problem Signature 09: Exception OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1033 I've been looking online but so far I keep finding mixed results on what could be the fix for this and was wondering if anyone here has ever ran into this issue before. I read that this issue could be because of Security Update for Microsoft Windows (KB2449742) and that by uninstalling it I would be able to fix this issue, however I was not able to locate this anywhere in the server. Here's the link if interested Patch wise, everything is up to date. Also, I tried running hotfix KB2688730 to see if that would work after doing some research online, however the hotfix is not applicable to the computer. If anyone could provide some information on how to fix this and get the task scheduler running again it would be extremely helpful!

  • Requiring SSH-key Login From Specific IP Ranges

    - by Sean M
    I need to be able to access my server (Ubuntu 8.04 LTS) from remote sites, but I'd like to worry a bit less about password complexity. Thus, I'd like to require that SSH keys be used for login instead of name/password. However, I still have a lot to learn about security, and having already badly broken a test box when I was trying to set this up, I'm acutely aware of the chance of screwing myself while trying to accomplish this. So I have a second goal: I'd like to require that certain IP ranges (e.g. 10.0.0.0/8) may log in with name/password, but everyone else must use an SSH key to log in. How can I satisfy both of these goals? There already exists a very similar question here, but I can't quite figure out how to get to what I want from that information. Current tactic: reading through the PAM documentation (pam_access looks promising) and looking at /etc/ssh/sshd_config. Edit: Alternatively, is there a way to specify that certain users must authenticate with SSH keys, and others may authenticate with name/password? Solution that's currently working: # Globally deny logon via password, only allow SSH-key login. PasswordAuthentication no # But allow connections from the LAN to use passwords. Match Address 192.168.*.* PasswordAuthentication yes The Match Address block can also usefully be a Match User block, answering my secondary question. For now I'm just chalking the failure to parse CIDR addresses up to a quirk of my install, and resolving to try again when I go to Ubuntu 10.04 not too long from now. PAM turns out not to be necessary.

  • apache2 defaultsite redirect but not virtual host

    - by MMM
    I'm trying to set up a new server with several virtual hosts but also such that if the requested fqdn doesn't match a virtual host then the request is redirected to http://example.com/log.php?url=fqdn I have got the default host redirecting as desired however the virtual host that I have defined doesn't work. I'm testing using a different host and curl -I http://hostname.example.com:8080/ on the command line to read the html headers to check for the redirect header directly rather than following it with a browser (to avoid any caching issues). I have defined a virtualhost as the fqdn of the server but when I use curl to request that virtualhost I get redirected. If I request the server by any other name which doesn't have a virtualhost defined I also get redirected. apache version is 2.2.16 on ubuntu The config (concatenated together in order from a couple of different files) is as follows: Listen 8080 NameVirtualHost * <VirtualHost _default_> ServerAdmin [email protected] RewriteEngine On RewriteRule ^(.*)$ http://example.com/log.php?url=%{HTTP_HOST}$1 [R=302,L] </VirtualHost> <VirtualHost *> <Directory "/var/www"> allow from all Options Indexes </Directory> DocumentRoot /var/www ServerName hostname.example.com </VirtualHost> I've also tried ServerName values of hostname.example.com:* and hostname.example.com:8080 In case I wasn't clear enough: anything.anything.any/something requested from my server should redirect to example.com/log.php?url=anything.anything.any/something foo.example.com (not defined as a VirtualHost) requested from my server should redirect to example.com/log.php?url=foo.example.com hostname.example.com (defined as a VirtualHost) requested from my server should return an html document anothername.example.com (also defined as a VirtualHost) requested from my server should return an html document It turns out that because the servers own fqdn is hostname.example.com that gets redirected to the Default VirtualHost even if there is a named VirtualHost for it. Other fqdn's that are not the same as the servers fqdn work as I intended.

  • How to test email spam scores with amavis?

    - by CaptSaltyJack
    I'd like a way to test a spam message to see its spam scores that SpamAssassin gives it. The SA db files (bayes_toks, etc) reside in /var/lib/amavis/.spamassassin. I've been testing emails by doing this: sudo su amavis -c 'spamassassin -t msgfile' Though this yields some strange results, such as: Content analysis details: (3.7 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- 3.5 BAYES_99 BODY: Bayes spam probability is 99 to 100% [score: 1.0000] -0.0 NO_RELAYS Informational: message was not relayed via SMTP 0.0 LONG_TERM_PRICE BODY: LONG_TERM_PRICE 0.2 BAYES_999 BODY: Bayes spam probability is 99.9 to 100% [score: 1.0000] -0.0 NO_RECEIVED Informational: message has no Received headers 0.2 is an awfully low scores for BAYES_999! But this is the first time I've used amavis, previously I've always just used spamassassin directly as a content filter in postfix, but apparently running amavis/spamassassin is more efficient. So, with amavis in the picture, how can I run a test on a message to see its spam score breakdown? Another email I ran a test on got this result: 2.0 BAYES_80 BODY: Bayes spam probability is 80 to 95% [score: 0.8487] Doesn't make sense, that BAYES_80 can yield a higher score than BAYES_999. Help!

  • Apache+PHP on Windows Server 2008

    - by Álvaro G. Vicario
    I've installed Apache/2.2 and PHP/5.3 lots of times under Windows XP, Windows Vista and Windows Server 2003. The official *.msi installers work fine and configure everything. Now I need to install them into a Windows Server 2008 R2 Standard 64-bit box and I'm facing nothing but problems: There are no official 64 bit binaries for Apache and no binaries at all for PHP (official or third-party). It's alright, I'll do with good 32 bits, but it's kind of surprising. Official documentation is vague, generic and completely unaware of UAC or any recent Windows security feature. The PHP installer is unable to configure mod_php and the Apache installer is unable to configure... well, Apache. After three hours I've finally reached the point where I'm installing everything in the root folder and assigning full control access to all users in all files and directories and all I've got is a PHP-less Apache server that's able to serve static pages. So I guess it's time to stop and think. My question is: Has anyone installed an Apache+PHP production server under Windows Server 2008 in a serious, secure and reliable way and documented the whole process? Or should I just find a bundle like XAMPP and the like that requires no installation? === EDIT === I've installed Xampp Lite 1.7.3 and everything was working in 5 minutes. I'd still like to find some documentation about installing the original packages: XAMPP installs tons of stuff I don't need and offers no tool to enable and disable PHP extensions.

  • DFSR NTFS Permissions Not Working!??!

    - by megadood
    I have two windwos 2008 standard servers running DFSR okay. I can create a file on one server, it is replicated to the other okay etc. I have the namespace shared folder on each server shared with full control administrators / everyone change/read permissions. I then browse to the folder on server 1 e.g.\server1\namespace\share\folder1. I right click the folder, and configure the NTFS permissions as I would like for example Adminsitrators Full Control / One User Read/Write Access / No other users in the user list. I save this and then double check the second server e.g. \server2\namespace\share\folder1. I right click the same folder name as before and can see the NTFS permissions have replicated accordingly. I right click the folder and go to properties - security - advanced - effective permissions and select a user that shouldnt be able to get into that folder e.g. testuser. It agrees with the NTFS permissions and shows that testuser has no ticks next to any permissions so should be denied access. I logon to any network PC or the server as testuser. Browse to \server1\namespace\share\folder1. It lets me straight in, no access denied messages. The same applies to server2. It seems as thought all my NTFS permissions are being ignored. I have 1 DFS share and then all the subfolders are a mixture of private folders and public folders so need the NTFS permissions to work ideally. Any idea whats going on? Is this normal? From my tests all users can access any DFSR folder under the namespace\share which is quite worrying. Thanks

  • Windows Image Backup - renamed folder now restore cannot find any backups

    - by Schneider
    A while back I decide to create a couple of Windows Image Backups of my workstation at various points during installation from clean. While doing this I decided to rename the folders containing the VHDs from 'Backup <Date>' to something else of my choosing. I didn't bother testing at the time that the restore still worked. Now I come to use these backups for doing a bare metal restore to a different computer. The problem is restore cannot 'see' any of the backups. So I have deduced that maybe I need to rename them back to the 'Backup <Date>' pattern unfortunately I cannot determine the exact values that would have originally been used here. I have tried by best guest but the images still cannot be found. I have tried doing both a network and a usb hdd restore. No luck on either. P.S. I know I can retrieve files from within the VHDs, the problem is I am trying to save myself time of reinstalling lots of big applications... not trying to recover data.

  • Network profile reverts to 'Unidentified' following Windows Update reboot

    - by user140575
    I have searched high and low for a solution to this problem. I have multiple servers running Windows 2000 Server as well as Windows Server 2003, 2003 R2, and 2008 R2. All of these servers are on the same Active Directory domain. The servers run showing the network profile as Domain Network, which is fine and correct. However, when a Windows update is installed, the server changes the profile to Unidentified Network once it has rebooted. This then doesn't allow any traffic to the server. For security reasons, we can't turn the firewalls off for. The only way to fix the problem is to physically be in front of the machine and work on it to change the profile back. Once the Profile has been reinstated to the Domain profile, it will be fine until the next month's update. This happens on all the Windows software mentioned above. The machines are not all identical, so it's not a hardware problem either. If anyone can help I'd be very grateful.

  • Slow upload speeds with pfsense virtual appliance

    - by Justin Shin
    I have a pfSense virtual appliance set up in front of a Windows server. The pfSense appliance has been configured with two L2L IPSec VPN sites and not too much else. The appliance has two vNics which both exist on the same VLAN, but one is "WAN" and the other is "LAN." When I run speedtest.net on my Windows server when I have configured it to use a static WAN address and gateway, I get great speeds - maybe around 50 down, 15 up. However, when I configure it with a private IP address, I get similar download speeds but terrible upload speeds - around 2 or 3 Mbps consistently. I used Wireshark to see what gives but there didn't appear to be too much helpful information there, or I just could not find it. Besides the L2L VPNs, other configurations include: Automatic Outbound NAT Virtual P-ARP IP for the Windows Server WAN Firewall rule to allow * to * on RDP WAN Firewall rule to allow * to * (enabled this just for testing... didn't help!) No DHCP or any other services besides IPSec VPN No Errors LAN or WAN No collisions LAN or WAN I would be happy to post the full config file if it would help. I've been scratching my head at this one all day!
