• Is MS Forefront Add-in for Exchange server detecting HTML/Redirector.C incorrectly?

  - by rhart

  Users of a website hosted by our organization occasionally send complaints that our registration confirmation emails are infected with HTML/Redirector.C. They are always using an MS Exchange Server with the MS Forefront for Exchange AV add-in. The thing is, I don't think the detection is legitimate. I think the issue is that the link in the email we send causes a redirect. I should point out that this is done for a legitimate purpose. :) Has anybody run into this before? Naturally, Microsoft provides absolutely no good information on this one: http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Trojan%3aHTML%2fRedirector.C&ThreatID=-2147358338 I can't find any other explanation of HTML/Redirector.C on the Internet either. If anyone knows of a real description for this virus that would be greatly appreciated as well.

• MacPorts, Fink, etc.

  - by Ben Alpert

  On my Mac OS X (10.5, soon to be 10.6) machine, how would you recommend I install various software that's been ported from Linux? I don't install such software very frequently, but I've been using MacPorts and it always seems quite slow, presumably because it has to compile the packages on-the-fly. I'd much prefer a package management system that has binary packages, saving me the need to compile things every time I want to download something new. I think Fink has binaries for some of the packages, but I usually see MacPorts recommended as the system to use. Which do you think works better and why? (Or is there another system that I haven't heard of?)

• FreeBSD 8.2 + Apache 2.2 + mod_auth_pam2: unable to authenticate

  - by zneak

  I've installed Apache 2.2 and mod_auth_pam2 from ports, but I can't get local UNIX authentication to work. When I access the protected part of my local website, I do get the authentication request, and with pam_permit.so, it works. However, when I change pam_permit.so to the real thing, pam_unix.so, I get this message in httpd-error.log: [error] PAM: user 'foo' - not authenticated: authentication error This is the relevant part of my Apache config, though I don't think it's the problem as it works with pam_permit.so: <Location /foo> AuthBasicAuthoritative Off AuthPAM_Enabled on AuthPAM_FallThrough off AuthType Basic AuthName "Secret place" Require valid-user </Location> This is my /etc/pam.d/httpd, though I don't think it's the problem either, since it works with pam_permit.so: auth required pam_unix.so account required pam_unix.so So what am I missing? What does it take to have pam_unix.so work for httpd under FreeBSD?

• Folder redirection save times are awful slow

  - by wbmeu

  I recently set up folder redirection for Documents on Server 2008, but it's painfully slow at the moment. My users are all using Visual Studio 2010, and a save takes 20-30 seconds (whereas it used to take 2 seconds locally). I understand this is because they are being saved to the server, and that takes time (though I did think it would be faster over a gigabit link, with servers on the same network). I enabled offline files on the share, set the option to All files or folders, and enabled Optimize for performance. I thought that this would pull all the files down locally (which I think it did), allow local editing of said files, synchronizing them quietly in the background from time to time (which it does not do - saves right to the share). Is there any way I can speed this process up a bit? Any other tweaks I can do?

• How do i have 4GB of video memory with a 1GB video card?

  - by Tomas Spc Yaczik

  I ran the direct X diagnostic tool to take a look at my graphics capabilities and its telling me that the approximate video memory is clocked in at 4096MB. That doesn't make any sense, how is that possible? The only things that i can think of were that DirectX was inaccurate so i looked at the graphics statistics of my computer on CPU-Z which was included with the motherboard and that's telling me i have "negative" 1988MB. Not only is that not 4096MB, but its giving me a negative number and i know for a fact that you can't have a negative amount of memory???!!! The only things i can think of that would be amplifying my video memory output is the PCIe 3.0 bus, or that the motherboard is somehow including the on board video chip set with the video card which only then is only 2GB of video memory, which still has to be being amplified by something. Any suggestions?

• Chrome Tab Ordering?

  - by Mark

  If I'm on the first tab, and I hit Ctrl+T, I want it to open next to (to the right of) the current tab. Is there an extension for this? I think I want to change the closed tab ordering too... but I can never remember how I like it until I play with it. I think move to the left tab is what I like. TabMixPlus gives me these options in FF, is there a similar extension available yet? Or some hidden options in Chrome?

• Google Chrome Enterprise - Any Gotchas?

  - by AJ

  Has anyone rolled out Google Chrome to a medium / large organisation? I would like to suggest it to our management (because I think it would work very nicely with some of our intranet applications), and I would like to find out what problems (if any) the rest of the world has been experiencing with it. Have you found any problems? I'm thinking of enterprise-level problems. I'm thinking that we can solve anything that requires a specific configuration / proxy setting / etc. I don't really know what I think might be a problem, but I wonder if there are any usability problems that occur when non-geeks use it? Or problems which only rear their ugly heads when you've got 50 users all doing something unexpected. Any helpful information or suggestions would be appreciated. Thanks. UPDATED: We tend to use Microsoft stuff, so Sharepoint, IIS, SQL Server, are typical building blocks of internal sites. (Thanks, @Jim, for reminding me to mention that).

• Cannot get git working

  - by Devin Dixon

  I'm trying to install my own git server with these instructions. http://cisight.com/how-to-setup-git-server-using-gitolite-in-ubuntu-11-10-oneiric/ But I am get stuck at this point. git clone --verbose [email protected]:testing.git Cloning into 'testing'... Permission denied (publickey). fatal: The remote end hung up unexpectedly And I think it has something to do with this: gitolite@ip-xxxx:~$ gl-setup tmp/john.pub key_read: uudecode Aklkdfgkldkgldkgldkgfdlkgldkgdlfkgldkgldkgdlkgkfdnknbkdnbkdnbkdnbkfnbkdfnbkdnfbkdfnbdknbkdnbkfnbkdbnkdbnkdfnbkd [email protected] failed fprint failed I always get the fail and I think its preventing me from cloning repo.The repo is there along with gitolite-admin.git repo.

• Logitech Optical Mouse Frozen In Middle of Windows XP Pro Screen

  - by Code Sherpa

  I have a Logitech Optical Mouse/Keyboard. I have been using them just fine with the system drivers for almost a year now. I recently updated my Kaspersky software and rebooted. Now the mouse is frozen in the middle of my screen. I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer. Things I know / have tried: When I boot on the problem computer, I am able to use the keyboard, but not the mouse. I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter. I bought new batteries for the mouse and that didn't matter. I have tried the mouse/keyboard on another computer and the mouse works just fine there. My suspicion is that the Kaspersky install has overwritten a driver of some sort. Things I have not done (and would appreciate detailed steps if you feel this is the way to go): 1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall. Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device? 2) Update my BIOS. Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version. Thanks for your help.

• Where is the actual content in a TCP segment

  - by packetloss

  When I email something or download a program, or do anything else over a network, where in the segment is the actual content? If I am emailing a 20KB word document, and the maximum data field size in a segment is 1500 bytes, does that mean it takes about 14 segments to mail my document wherever it is going? I get, I think, the OSI model and I have a decent grasp of the IP protocol. I think I understand the concept of header wrapping of each successive layer in the protocol stack. What I can't get a definitive answer to is where does the actual content go in a TCP segment? Is that the datagram? Maybe the fact I am asking proves I have no clue... Many thanks.

• VPN Network intermittantly fails to provide internet: What could be possible causes

  - by Jake M

  We have a small office with our own VPN setup. We occasionally experience failures in our internet connection where we cannot access the internet. Most of the time the internet connection will resume by itself(without me doing anything) after a period of time(10 mins). Would you be able to suggest possible causes of the connection failure so I can then go and run some tests? Our network architecture is like so: A 'Billion' brand router that is connected to the internet via phone cable and then connected to our Cisco Switch A Cisco Switch/Bus which is connected to all our office nodes, our external harddrive and also to our router as stated above. All connections are via ethernet cable A series of work computers(nodes) connected via ethernet cable to the Cisco switch. Our ISP is TPG Australia We have a Virtual Private Network All the ethernet cables are about 3 years old Do you think that the causes of our intermittant connection problems could be due to the following: Data collisions in the ethernet cables Old/Faulty ethernet cables Our ISP has bad service Can you think of any other causes of the problem?

• Should you disable page file with SSD?

  - by Pyrolistical

  I've been reading this question, and it has a lot of great information. But assuming you have more than enough ram, I think page file should be disabled on SSD to extend the life time. I know you would lose the core dump on crash, but not many people need that information. From my understand without a page file as you reach the limit of your ram that might trigger thrashing on disk. But for SSDs there is no concept of thrashing, reads are fast. What do you guys think?

• Submit form to another domain

  - by doubter

  I need to access the result of submitting a form to a website. There is a web site where you complete a form and it posts the information using ajax and then tells you if you have their service in the are or not. I'd like to be able to do this from my web page, which means posting the information required by the form to their server and getting the result. The problem is I get "403 Forbidden", I think it's because the "Origin" being a different domain. Is there anyway that I can the response from the server on my website? I thought about php_curl (used once with google docs api) but would like to know what you guys think it's the best way.

• Asterisk, IAXModem & Hylafax how-tos?

  - by Brian Postow

  I'm trying to set up Asterisk and IAXModem to send faxes via T38 (Yes, I know I'm swatting a fly with a Buick...) However, since I'm trying to do something so small with a product so large, I'm having trouble finding samples or how-tos that show me how to set this up. I've got all three installed, and I THINK I have my IAXModem config correct. I'm pretty sure that I have Hylafax correct (I've used it with T38Modem) so, I need to know which of the Asterisk samples I need to use, and how to use them. I think I want to use some combination of iax.conf, iaxprov.conf, sip.conf and sip_notify.conf. But I'm not sure where to put them, or what to change... I'm sure that the answer is RTFM, but I'm not sure WHICH M, or where in it to R... thanks.

• How can I tell if ZFS (zfs-fuse) dedup/compression is applied to a particular file?

  - by asari

  I have a zfs formatted partition using zfs-fuse for linux (Ubuntu). I had used it for a while, and then enabled dedup and compression on it (zfs set compression=on/dedup=on). Now I think I have some files that are dedup'ed and compressed, and file that are not yet. It was OK, but sometimes I was confused. Let's see, following command would consume almost 4GB of my zfs storage: cp oldfile.4GB newfile.4GB .. and this would consume almost zero: cp newfile.4GB newfile.4GB.2 This is because the old file is not yet compressed, so dedup not happened, I think. My idea is -- if I can find old files that are not yet dedup/compressed, I can perform batch copy/rename/remove them to eliminate duplicity and redundancy. But how I can check that? I know I can re-copy whole contents of my storage should work (even better with checking the time stamp of each file), but I'd be happier if I have zfsstat-like tool that shows some file properties.

• Raid0 performance degradation?

  - by davy8

  Not sure if this belongs here or on SuperUser, feel free to move as appropriate. I've noticed the performance on my RAID0 setup seems to have degraded over the past months. The throughput is fine, but I think the random access time has increased or something. In use I generally see about 1-5mb/sec when loading stuff in Visual Studio and other apps and it doesn't seem like the CPU is bottlenecking as the CPU utilization is pretty low. I don't recall what Access Time used to be, but HD Tune is reporting 12.6ms Read throughput is showing as averaging about 125MB/sec so it should be great for sequential reads. Defrag daily and it shows fragmentation levels low, so that shouldn't be an issue. Additional info, Windows 7 x64, Intel raid controller on mobo, WD Black 500GB (I think 32mb cache) x2.

• Can't start the Windows Phone Emulator

  - by Louis

  When I try run/debug an app in the emulator I get this error: And in Visual Studio's Error List console it simply says: 0x80131500 I haven't worked on this project for about a week, but it was working then. I checked the BIOS and everything is enabled (as it was last week). I don't think this is related, but yesterday, I did upgrade my system SSD and used the Samsung Data Migration Tool to clone my drive. I've tried repairing the Windows Phone SDK 8.0, but that didn't help. Are there any other things I can try? I really don't think it's related to the SSD. Hyper-V related services: I can't start any of these either.

• Gmail: Find emails that do not have a label

  - by DGHelp

  Hello, I am trying to search for all of my mail that does not have a label. I label all of my mail then archive it but I think throughout the years I have forgotten some. Is there anyway I can search for all mail that does not have a label? Idea I had: Go to my All Mail and apply an arbitrary label to all of them, then go to each of my labels and remove my arbitrary one. However, is there a quick way to add a label to ALL mail for this idea to work? Also, I think this will apply it to even my sent mail instead of just mail that was sent to me? Any ideas/suggestions would be great. Thanks!

• kernel: journal commit I/O error

  - by jasondewitt

  I am having some problems with a Dell 1950 server. I am installing RHEL 4.6 along with Oracle and some other software on here. I am randomly getting an error message saying "kernel: journal commit I/O error" on my ssh session and on the monitor I have hooked up to the server I see an error scrolling by that says "EXT3-fs error (device sda5) in start_transaction: Journal has aborted." It has happened several times but never at the same point during the install. Actually, this last time the system was up and running and I was just trying to import a database into oracle. This has happened on several hard drives, so I'm pretty sure that is not the problem. This makes me think the raid controller is going bad. What do you guys think? ** UPDATE ** Pretty sure it was a bad hard drive. I threw another drive in the server and it's been running for about 48 hours with out problems.

• Facebook verify account

  - by dman

  I can't login to Facebook because they think someone tried to hack my account. To verify it's really me they present me with photos that my friends have been tagged in and ask me to give them the correct names of who is tagged in the photos. Now because alot of my friends think it's funny to tag themselves in random photos of others, or tag themselves as objects in photos, I can't successfully get all 10 correct. I also have alot of friends of friends that have added me that I don't know closely enough to identify the back of their head in a distant blurry photo. Facebook only allows one attempt per hour to try this. How am I supposed to restore my account when they have such a stupid method to prove identity?

• Access forbidden! using xampp on macosx 10.5

  - by erikvold

  I installed xampp back around January 2009, and CF8 to test coldfusion on my macbook (note: I do not think that this issue is related to CF, but only xampp). I only ever used the apache part of xampp, and this was working for over a year. In the last couple of months at the most I've started getting the following error message (even for none CF sites, and non .cfm pages, the error occurs for .html files..): Access forbidden! You don't have permission to access the requested object. It is either read-protected or not readable by the server. If you think this is a server error, please contact the webmaster Error 403 erikvold.lan Sun Mar 21 20:58:45 2010 Apache/2.2.11 (Unix) DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.7l PHP/5.2.9 mod_perl/2.0.4 Perl/v5.10.0 As far as I recall I haven't made any change, so it's like it was working for a year then just stopped working..

• Cisco FC SAN switch decision

  - by Chopper3

  I've got to buy a bunch of FC SAN switches in the next week or so, I have to, and want to, buy Cisco MDSs. Servers are HP BL490c G6's in C7000 chassis with Virtual-Connect Flex-10 ethernet interconnects and VC FC interconnects (Emulex HBAs btw), all running ESX 3.5U4 (for now). I think I've only really got two choices; MDS 9509's with dual-supervisors with a single 48-port 4Gb FC card MDS 9222i's with single supervisor and the built-in 18-FC-port/4-GigE-FCIP-port option Both have the same functionality (I think, buying the enterprise licence btw), both have plenty enough performance and adequate ports for now and the next three years. The 9222i's are about 55% the price of the 9509's - logic says get the 'i's but will I really miss the dual-supervisors? I've got lots of 9509's with dual-supervisors that I'm very happy with but I'm not sure I've every benefitted from the dual-sups in the past and they are nearly twice the price - but if I don't buy them and miss them I can't retrofit them later. What are your thoughts?

• Googlebot cant access my site webmaster tools reply Unreachable robots.txt

  When I try to fetch my site as a googlebot in webmaster tools it return Unreachable robots.txt, after investigate I understood google bot can see my server: tcpdump | grep google it return that google can access my server with IP 66.249.81.172 or 66.249.75.111. but there is not any think in access log or error log or other apache logs. cat access_log | grep google or cat error_log | grep 66.249.81.172 Other bot (bing,...) can access apache but google cant. there is not any problem in my robots.txt or its permissions because as you know robots.txt is not necessary so I delete it but again webmaster tools returned Unreachable robots.txt not 404 not found! information about server: Server OS : CentOS 6 Web Server : Apache 2.x Firewall : IPTables is stoped SELinux is Disabled There is not any think else for security on my server. how can I investigate the problem and is there any other command that can help me to find the problem.
