• Having Troubles Getting My Apache Server Online(NodeJS and Apache)

  - by Jeff Armingol

  I am new here. This is my situation. I am using nodejs modules, serialport2 and socket.io, because I am trying to forward the data from my arduino hardware through serialports. In my server side script, I read the data then forward it to the client side. Now I am using Apache to serve the html page,which is the client side. I am running Nodejs on port 8000 and Apache on port 80. It is running OKAY when I view it in my browser typing localhost:80. The data is appearing and seems fine. Now when I tried to get my Apache server online using a Free DDNS provider(http://www.noip.com/) and my port80, it loaded the webpage but there are no data appearing on the page. What seems to be the problem here? Really need your expertise and advice. Thanks in advanced!

• How to enable hotlink protection without hardcoding my domain in the Apache config file?

  - by Jeff

  Been surfing around for a solution for a couple days now. How do I enable Apache hotlink protection without hardcoding my domain in the config file so I can port the code to my other domains without having to update the config file every time? This is what I have so far: RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://www\.example\.com [NC] RewriteRule \.(gif|ico|jpe|jpeg|jpg|png)$ - [NC,F,L] ... And this is what Apache suggests: SetEnvIf Referer example\.com localreferer <FilesMatch \.(jpg|png|gif)$> Order deny,allow Deny from all Allow from env=localreferer </FilesMatch> ... both of which hardcode the domain in their rules. The closest I came to finding any info that covers this is right here on ServerFault, but the conclusion was that it cannot be done. Based on my research, that appears to be true, but I didn't find any questions or commentary dedicated soley to this question. If anyone's curious, here is the link to the Apache 2 docs that cover this topic. Note that Apache variables (e.g. %{HTTP_REFERER}) can only be used in the RewriteCond text-string and the RewriteRule substitution arguments.

• What desktop boards support VT-D or IOMMU?

  - by Jeff Shattock

  I'm looking for a desktop board that supports either VT-D (Intel) or IOMMU (AMD) technology. This is the IO virtualization technology, not VT-x for CPU virtualization. I've found a list of chipsets that are purported to have this, but every board I look at, the vendor has decided to not support that feature. I would really prefer a desktop board over a server board for this. Does anyone have a specific model that is known to support this technology?

• CPanel: Are there logs for login attempts?

  - by jeff

  Hello, I tried to login into a cpanel account that hasn't been accessed for a few months and discovered that my login details no longer worked. When I reset the password and gained access into my domains control panel, my email password also didn't work. Upon that first attempt I was given a message reading "Brute force attempt..." So, does cpanel keep a list of logins? or login attempts? Thanks for any help!

• Dynamically blocking excessive HTTP bandwidth use?

  - by Jeff Atwood

  We were a little surprised to see this on our Cacti graphs for June 4 web traffic: We ran Log Parser on our IIS logs and it turns out this was a perfect storm of Yahoo and Google bots indexing us.. in that 3 hour period, we saw 287k hits from 3 different google ips, plus 104k from yahoo. Ouch? While we don't want to block Google or Yahoo, this has come up before. We have access to a Cisco PIX 515E, and we're thinking about putting that in front so we can dynamically deal with bandwidth offenders without touching our web servers directly. But is that the best solution? I'm wondering if there is any software or hardware that can help us identify and block excessive bandwidth use, ideally in real time? Perhaps some bit of hardware or open-source software we can put in front of our web servers? We are mostly a windows shop but we have some linux skills as well; we're also open to buying hardware if the PIX 515E isn't sufficient. What would you recommend?

• Why is nslookup reporting two IP addresses?

  - by Jeff

  I made a DNS change a few hours ago and I just ran the following command with the following output: nslookup mydomain.com ns1.mynameserver.com Server: ns1.mynameserver.com Address: 111.111.111.111 Name: mydomain.com Addresses: 222.222.222.222 333.333.333.333 222.222.222.222 is old IP. 333.333.333.333 is the new IP address. Why are they both showing up? Since I'm querying the authoritative DNS server directly, shouldn't only the new IP address be shown?

• Virtual OS using same Wallpaper as Host

  - by Jeff

  Greetings, I'm running a guest Linux OS on top of Windows XP, which rotates its wallpapers using the PowerToy Wallpaper Changer. I'm hoping for a way for my guest OS to somehow detect which wallpaper the host is using, and automatically switch to it. Why? Because if I run my guest OS in seamless mode and have transparent windows, I want the transparent background to match the host OS. It looks nice that way :). A couple tidbits of relevant information: Guest OS is Peppermint Ice (Ubuntu based) Host OS is Windows XP VirtualBox as virtualization software I realize this is somewhat breaking borders between the host and the guest, but I want my pretty rotating wallpaper! I'm guessing there is a way using scripts and shared folders or something similar, if not by means of just querying the host OS.

• Why is idle windows VM using so much CPU?

  - by Jeff Shattock

  I have 2 VMs running as guests on a KVM virtualization platform running on Ubuntu 10.04. One VM is an Ubuntu 10.04 system, the other is a Windows 7 system. When both machines are completely logged out, the Linux machine uses 1% CPU, the Windows one 45-50%, according to top. The graphs in virt-manager seem to back this up. Theres nothing installed on the Win7 image that would be running in the background; its as fresh as can be. Why is the Windows VM using so much more than the Linux VM, when both are logged out and idling?

• Video card not detected in POST on initial boot.

  - by Jeff M

  I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

• Linux IPv6: DHCP and /127 prefixes

  - by Jeff Ferland

  I've tried multiple pieces of DHCP client and software in attempting to setup a solution for allocating a /127 prefix to virtual machines so that each maintains its own layer 2 isolation. Because there would only be one host assigned to each network, a /64 is impractical. While the prefix size could reasonably be somewhere in the /64-127 range, the crux of the problem has been the same regardless of the software used in configuring: the DHCP call to bring up the interface uses the address advertised by DHCPv6 and inserts two routes: the /127 given by the router advertising packets and a /64 as well. Any thoughts on why I'm getting the additional route added across dhcp client vendors?

• How do I create a calendar appointment from an e-mail in Outlook 2011 for Mac?

  - by Jeff O

  How do I create a calendar appointment from an e-mail in Outlook 2011 for Mac? In Windows, the e-mail content and attachments are carried over just by dragging and dropping. Dragging and dropping on the Mac doesn't work. Is there any other function to take an e-mail and make it a calendar appointment? I'm trying to avoid emailing it to myself. Edit: Since someone went to the trouble to make email2task, is it safe to assume this feature is not available otherwise?

• View Public Key in Domain Key for a Domain

  - by Josh

  Using Jeff's blog post I'm creating domain keys for my account. I wanted to verify the setup using Get or Host command with Bind for Windows but I'm lost one of the commands. I can see view the _domainkey. txt file with this command: host -t txt _domainkey.stackoverflow.com but I'm at a loss at how I'd find the selector record. Jeff points out it can be anything before the before the period in "._domainkey.domain.com" but how would I list all records if I didn't know the exact query name? Is there a wildcard I could use to view all TXT or all records under this section?

• Programatically Determine Exchange Attachment Limit

  - by Jeff Ballard

  Is there any way to query the exchange server to determine the maximum attachment file size? I'd be doing this in ASP.NET/C#. I'd like to be able to validate the file they want to attach is not over the limit before the user attempts to send the file to the server as opposed to having the server send back an exception when it attempts to attach the file and it discovers the file is too large. I've also posted this question about this on stackoverflow.com as well - I figured a sysadmin for Exchange may have an answer as well as a developer. Hopefully I do not incur the wrath of the stackexchange gods.

• Error mounting samba share, cannot mount block device xxxx read-only

  - by Jeff Ward

  After installing Ubuntu 12.04, I'm trying to mount a samba share from Windows under Linux, using a scripted command that's always worked, and the server hasn't changed. The error is as follows: $ mount -t cifs //<host>/<share> /media/<share> -o username=<user>,password=<pass> mount: block device //<host>/<share> is write-protected, mounting read-only mount: cannot mount block device //<host>/<share> read-only $ I've read a lot of discussions about permissions, but unfortunately, that wasn't the issue. I'm submitting my own answer below for reference, hope this helps someone else.

• password protect apache user directory using system passwords

  - by Jeff

  I have set up Apache to check user passwords using these modules: LoadModule authz_user_module modules/mod_authz_user.so LoadModule authn_file_module modules/mod_authn_file.so LoadModule auth_basic_module modules/mod_auth_basic.so However, these modules require me to manually add everyone to a new password file (which requires every user to type in their password). Is there a way to have Apache check the system passwords, so that anyone who can ssh can use the same password for web login?

• Time issues on the Network -- How to find the Root Cause

  - by Jeff

  A number of application servers started erroring out in my domain. Troubleshooting led me to a missconfiguration of NTP. I fixed the issue, but I don't know how the issue arose in the first place. The only errors I can find are System Error: 1097 Source: useenv System Error: 1058 Source: useenv System Error: 1030 Source: useenv System Error: 1000 Source: mmc How else can I find out why NTP started acting up on my domain? Is there any troubleshooting steps to diagnose why my DC started pulling from a random timeserver with the wrong time? EDIT: Current issue actually remains: the two 2003 DCs are not syncing with the PDC (a 2k8 box). w32tm /resync -- The computer did not resync because no time data was available.

• Transport rule - Exchange 2010

  - by Jeff

  I have two transport rules on my exchange server. One is: > Apply rule to messages: From users that are 'outside the organization' > and when any of the recipients in the To or Cc fields is a member of > '[email protected]' Forward the messageto sender's manager > for moderation The second is: Apply rule to messages from a member of '[email protected]' and sent to users that are 'outside the organization' forward the message to the sender's manager for moderation. nointernetmail is a distribution group, and each user has the managed by set to there local manager. However these transport rules do not work, internet mail is still sent and received without issue. I have read various tutorials / articles of how to do this on sites such as msexchangeblog and even microsoft technet, however even after following the guides I am still unable to have this function properly. Any help is appreciated.

• Suggestions? Password & Encrypted Read/Write File like a Mac (.dmg or .SparseBundle) also R/W on Windows, Ubuntu

  - by Jeff Drew

  For years I have used .dmg or .sparsebundle (Encrypted and Password Protected) to safely keep home directory backups on my Mac. Now, I am looking for a similar Full Permissions/Read/Write that maintains an encrypted, and password protected file that it Tri-Platform. I'd like to have the future ability to use it on Mac OS X, Windows 7/8, and Ubuntu (current releases+). I appreciate your recommendations. Thank you. (I like mounting a DMG and having a file directory structure that can be easily maintained and organized. When done, un-mounting the file.) (I've seen Windows tools to open encrypted DMG files? and I will explore these options, but with the desire to also keep the file accessible on on three OSes, someone might have additional suggestions.)

• Troubleshooting an overheating CPU

  - by Jeff Fry

  I & my father just recently put together a new PC. Specs below. From the very beginning, on boot it will often complain that the CPU is too hot. If I sit in BIOS and watch the CPU, it'll drop back down from red to blue (<72C), at which point I've tended to just boot into Windows...and haven't had any problems. In fact, I've played a couple hours straight of Skyrim at max settings, and not had any visible issues. That said, I've occasionally walked away & come back to find that it's crashed. Yesterday, it crashed (while idle) twice in 12 hours, which shifted the balance from busy-with-life to nervous-I'm-about-to-melt-something. I just installed Core Temp which is showing my 4 cores fluxuating between 70-98C. I'm guessing at this point that the CPU fan may be incorrectly installed or defective. My first thought is to either (a) add water cooling (which the case supports) and / or (b) replace the CPU fan with an after-market one. That said, I'm very open to suggestions. A note, while I certainly don't want to burn money here, I have a baby coming any day now and am still unpacking from a recent move so if I have a choice between an option that costs money and another that takes a while...I'll happily spend a bit extra. Side question: Should I be nervous to even have this on at this point? Let me know if there's something useful I could add to my report. Otherwise, I'm looking forward to your suggestions! Thanks.

• How do I prevent a tar pipe from causing swapping?

  - by Jeff Shattock

  I have a rather large filesystem that I need to transfer from one Linux server to another. I figured the best way to do this was via a tar/netcat pipe arrangment, something like tar c . | pv | nc blah blah blah And it works great, the network stays fairly saturated, life is good. Until the source machine starts swapping. The files are on a raid on the source system, so the read speed is much faster than the write speed on the other end. Since the dest machine hasnt picked up the data yet, the source machine needs to stick it somewhere, so into RAM it goes, until there is no more free RAM. It then starts swapping, which is horribly painful since that machine has its OS installed on a somewhat slow CF card. Both machines have 4GB of physical ram, 64 bit Ubuntu 9.04 server. GigE link between them. How do I prevent this swapping? Can I put a "speed-limit" on the tar or netcat process so that the transfer speed doesn't overwhelm the write throughput on the destination end? The man pages didn't list anything, but there might be something I'm overlooking.

• Rackspace Cloud Sites API (Not Cloud Servers)

  I'm looking for a way to pull data from my Rackspace Cloud SITES account. The data I want to pull is bandwidth, diskspace, and compute cycles (all available from control panel). I'd like to set up my own warning system, to be notified if I'm close to my limits on any given month. Does anyone know of a way/API to do this?

• How do I update my servers' domain name for Reverse DNS?

  - by Jeff

  I'm updating my mail servers' rDNS and I think I have it all figured out except for one thing. When I installed my OS (Debian Etch), the installer asked me to enter the "domain name". Is the "domain name" updated by using the hostname command? If so, which config file(s) are updated when using the hostname command? If not, how do I change my servers' domain name? My current /etc/hosts: 127.0.0.1 localhost 67.228.178.164 mrspock.example-old.com mrspock My current /etc/hostname: mrspock $ hostname -f mrspock.example-old.com I need to update hostname -f to be mrspock.example-new.com.

• What Device/System to use as a "router on a stick"

  - by Jeff Leyser

  I need to create several distinct VLANs, and provide a way for traffic to move between them. A "router on a stick" approach seems ideal: Internet | Router with Trunking Capability ("router on a stick") * * Trunk between router and switch * Switch with Trunking Capability | | | | | | | | | | | LAN 2 | LAN 4 | | 10.0.2.0/24 | 10.0.4.0/24 | | | | LAN 1 LAN 3 LAN 5 10.0.1.0/24 10.0.3.0/24 10.0.5.0/24 We have trunk-capable Layer-2 switches. The question is what to use as the router on a stick. My choices seem to be: 1) Use an existing Cisco 5505 ASA firewall. It appears the ASA can do the routing, but it's a 100Mbps device, and so seems sub-optimal at best 2) Buy a router. This seems overkill. 3) Buy a Layer-3 switch. Also seems overkill. 4) Use an existing Linux Box as a router 5) Use a new Linux box as a router' 6) Something I'm not thinking of I think either (4) or (5) is my best option, but I'm not sure how to choose between them. I expect the amount of traffic that has to cross the VLANs to be somewhat small, but bursty. How much load does routing add to a CentOS machine?

• Printer Properties not sending the correct page size to program

  - by Jeff

  We have a Zebra 2844 Label Printer with 4"x3" labels in it. When we check the page settings in Windows XP, it is set to the correct size. When we go to print out of any program, it prints 4"x11". I have checked the page settings in one of the programs that we are using and it does show correctly the 4"x3" settings but prints at the incorrect 4"x11". I have followed the steps here Paper size: Printer Properties vs Page Setup and here Is there a way to programatically set the printer properties in windows? but have not been able to glean enough information to figure it out. If anyone can help, I would appreciate it!
