  • debian VM refusing all traffic apart from http

    - by james lewis
    I've got a VM with a fresh install of Debian (wheezy) and I've installed node and mongo on it. The VM is using a bridged network connection so I was expecting to be able to point my host machines browser at the ip address of the Debian VM (port 1337 for my node example or port 28017 for my mongo status page) and see one of the two services (node or mongo). My requests are refused though. As far as I can tell Debian allows all traffic by default and you have to manually configure iptables to drop traffic. I've checked iptables and it says it's setup to allow anything through. It looks like this: root@devbox:/home/jlewis# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination As a test I setup nginx and I was able to get to the nginx landing page from my host no problems so obviously http traffic is allowed. I then set nginx up to forward all traffic upstream to mongo - no problems there, I was able to see the status page. I then did the same for my example node server and again, no problems. So http traffic is fine, but all other traffic is blocked. Anyone know why debian might be refusing all other traffic other than iptables being setup to drop it?

  • Apache2 - rewrite a bunch of specified pathname URLs to one URL

    - by James Nine
    I need to rewrite a bunch of urls (about 100 or so) for SEO purposes, and there may be more being added in the future (probably another 50-100 later on). I need a flexible way of doing this and so far, the only way I can think of is to edit the .htaccess file using the rewrite engine. For example, I have a bunch of urls like this (please note that the query string is irrelevant, and dynamic; it could be anything. I was only using them purely as an example. I am only focusing on the pathname--the part between the hostname and query string, as marked in bold below): http://example.com/seo_term1?utm_source=google&utm_medium=cpc&utm_campaign=seo_term http://example.com/another_seo_term2?utm_source=facebook&utm_medium=cpc&utm_campaign=seo_term http://example.com/yet_another_seo_term3?utm_source=example_ad_network&utm_medium=cpc&utm_campaign=seo_term http://example.com/foobar_seo_term4 http://example.com/blah_seo_term5?test=1 etc... And they are all being rewritten to (for now): http://example.com/ What's the most efficient/effective way of doing this so that I may be able to add more terms in the future? One solution I came across is to do this (in the .htaccess file): RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ / [NC,QSA] However, the problem with this solution is that even invalid urls (such as http://example.com/blah) will be rewritten to http://example.com instead of giving a 404 code (which is what it is supposed to do anyway). I'm still trying to figure out how all this works, and the only way I can think of is to write 100 more RewriteCond statements (such as: RewriteCond %{REQUEST_URI} =/seo_term1 [NC,OR]) before the RewriteRule directive. For example: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} =/seo_term1 [NC,OR] RewriteCond %{REQUEST_URI} =/another_seo_term2 [NC,OR] RewriteCond %{REQUEST_URI} =/yet_another_seo_term3 [NC,OR] RewriteCond %{REQUEST_URI} =/foobar_seo_term4 [NC,OR] RewriteCond %{REQUEST_URI} =/blah_seo_term5 [NC] RewriteRule ^(.*)$ / [NC,QSA] But that doesn't sound very efficient to me. Is there a better way?

  • Cisco ASA 5505 and slow download speeds for Apple devices

    - by James
    For traffic routing through my ASA 5505, downloads for all Apple devices, including AppleTV iPad gen 1 IMac MacBook Pro are very slow. speedof.me show less than 1 Mbps download (where I should have 20 Mbps +), yet for any Windows-based device, the download speeds are in excess of 20 Mbps. The Windows device, including the iMac and MacBook Pro machines, are connected via ethernet cable. Why are Apple devices experiencing such pain? Is it an ASA setting, or something else? Thanks.

  • Can Linux report IP conflicts?

    - by James
    If a Red Hat or other Linux host has a conflict with an IP address, is there a way to have it display a warning message on the console or in a log, like Windows and MacOS do? i.e. my computer has an IP address configured (or received from a DHCP server) but finds another device on the network using the assigned address. Will it log the conflict?

  • Dell V105 printer and OS X 10.6

    - by James
    I am trying to get a Dell V105 printer to work with my iMac. It is running 10.6 and I have installed all the drivers on the Snow Leopard disk. I believe there is no official Dell driver but I have also heard the Dell printers are made by third parties that may sell the same printer under different names. There a quite a few Lexmark models that seem to look very similar and I have tried setting the driver to the 2600 series that looks very similar but that has not enabled me to print. Although it claims to give me the supply levels correctly. Can anyone help? Thanks for your time

  • Cannot find Ruby on Rails installed

    - by James
    I've managed to install Ruby and the gems install (rvm?) but now I'm stuck actually installing Ruby on Rails. Every time I execute, gem install rails Terminal says that it's fetching each file and that it successfully installed it: 1 gem installed However when I then run the rails command, I'm told that it's not installed and to run the gem install rails command again. I've attempted to install with sudo but the same thing happens. I've restarted after an install and that's not worked. Ideas?

  • Netinstalling CentOS if the gateway is in a different subnet

    - by James Lawrie
    I have a KVM host (A) running a virtual machine (B). They each have their own external IP address and the networking is setup using bridging between eth0 and br0 on A. B uses eth0, with A being the gateway. The problem is that the two external IP addresses are on different subnets (different /8s in fact) so by default, B claims it cannot reach A (Network Unreachable). I can resolve this by adding a static route on B: echo "any host gateway_ip dev eth0" > /etc/sysconfig/static-routes Modifying /etc/init.d/networking to reload the gateway after applying static routes (I only added the final line before fi): if [ -f /etc/sysconfig/static-routes ]; then grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do /sbin/route add -$args done route add default gw "${GATEWAY}" fi If I then restart networking, it comes online. How can I do this (or work around it some other way) prior to the system being installed, ideally inside an Anaconda kickstart file?

  • Remote logging for multiple Apache virtual hosts using syslog-ng

    - by James
    I'm running a couple Apache web servers that each have 4-8 separate virtual hosts on each of them. I'm trying to setup a dedicated log server that stores each virtual host access and errors logs in a separate directory for that virtual host. For example on the logging server, /var/log/remove/10.0.0.2/virtualhost1 contains access_log and error_log /var/log/remove/10.0.0.2/virtualhost2 contains access_log and error_log /var/log/remove/10.0.0.3/virtualhost3 contains access_log and error_log and so on... Right now I have it split up by host but I can't figure out how to do it additionally by virtual host. Here are the relevant lines from the logging server's syslog-ng.conf source r_src { tcp(ip("0.0.0.0") port(5140)); }; destination r_all { file("/opt/splunk/logs/$HOST"); }; log { source(r_src); destination(r_all); }; Any help would be appreciated. Thanks!

  • Why does a pdf file download result in varying bytes logged, all with sc-status 200

    - by Pat James
    I have a mojoportal CMS installation on an IIS7 server where users are reporting problems downloading a pdf file. It always downloads fine for me and most others, either displaying in browser or in Adobe Reader. Using logparser to query the IIS logs, all the responses are status 200 (OK) or 304 (Not modified), but the bytes sent vary quite a bit. Sometimes zero, some 211, some about half the full file size of 27059, and lots in between. Plenty show the full size of 27059. Do these other entries for smaller byte counts represent errors of some kind, correlating with the problems reported? Is this likely to be a browser/client issue or a server side problem? If there is any other info that would be helpful let me know. This is a shared hosting server though so I am somewhat limited in what I can dig into on the server.

  • Disabled admin account on Win 2008 R2

    - by James Bates
    I accidentally disabled the administrator account on an install of Windows Server 2008 R2 via the net user command. Now I cant get an elevated command prompt to re-enable the admin user, nor do any privileged operation that requires an admin password. Normally I would type in a password and click yes but there is no password field and yes is grayed out. How can I re-enable the administrator account?

  • Mixed network, Linux-to-Linux hostname resolution issues

    - by James
    At work we have an WinSBS domain at the heart of our network, which is all Windows PCs. The domain controller is acting as a DNS for these computers. I have recently added some personal use Linux machines to the network, without joining them to the domain. I have set up Samba with "wins server" pointing to the domain controller, which lets the Windows boxes resolve the Linux hostnames just fine. I also have resolvconf set up with the domain controller as a nameserver and the local domain as a searched domain, which lets the Linux boxes resolve the Windows hostnames just fine. However, the Linux boxes will not resolve other Linux hostnames at all. Given that I don't have control over the DNS server (I am not the network admin) and that at least one of the Linux boxes is not an always-on machine and is likely to change its LAN IP frequently (via DHCP), what service am I missing to make their hostnames visible to each other?

  • IIS6 Virtual SMTP server isn't coming back up automatically after a system restart

    - by Julian James
    I've got a virtual server running Win2008 RC2. I've set up IIS6 with a virtual SMTP server on it to be the mail provider for the websites I'm hosting there. It all works great, but if for some reason the server reboots (auto updates are still enabled - I'm trying to make this as little work as possible as we've got a Lot of clients), the IIS6 doesn't restart the SMTP server. The failure causes 500 errors on the current setup, so I'm spending half the day apologising. Any ideas? In Services I've set everything to come back up automatically, but still no dice. As soon as I restart the SMTP, no problems, all the mail gets sent. It's working perfectly, it just won't restart on it's own. I'd really rather not turn auto updates off as we're such a small company I just can't spare the time to be manually updating 15 copies of windows every time MS decide there's a security patch. All advice appreciated! BTW, I am a complete newb to these forums. I searched but couldn't find an answer, so please be nice. But firm. I've got to learn here.

  • OSX: sync Documents folder to Dropbox with version control

    - by James Porter
    I have ample storage in Dropbox to sync my entire OSX Documents folder, and I'd like to this just so that I have it anywhere I go. I found this question, which describes a method for doing this with symlinks. Seems good, the only problem is that it would be nice also to have everything under version control. I thought perhaps a better solution would be to set up my Documents folder as a git repo with a remote that I would push to in my Dropbox folder. Alternatively, just set up Documents as a git repo with no remote and then symlink it to Dropbox. Which of these two alternatives is preferable? What are some pitfalls I might not be thinking of with each? It also has occurred to me that some of the subdirectories of Documents are themselves git repos with github remotes. Would it cause problems for these subdirectories if I made Documents a git repo? If so, how do I get around this? Would making Documents an svn repo instead help? Is there a way to set up git so that this is not an issue?

  • Redirect local, not internal, requests using SuSEfirewall2 or an iptables rule

    - by James
    I have a server that is running a web application deployed on Tomcat and is sitting in a test network. We're running SuSE 11 sp1 and have some redirection rules for incoming requests. For example we don't bind port 80 in Tomcat's server.xml file, instead we listen on port 9600 and have a configuration line in SuSEfirewall2 to redirect port 80 to 9640. This is because Tomcat doesn't run as root and can't open up port 80. My web application needs to be able to make requests to port 80 since that is the port it will be using when deployed. What rule can I add so that local requests get redirected by iptables? I tried looking at this question: How do I redirect one port to another on a local computer using iptables? but suggestions there didn't seem to help me. I tried running tcpdump on eth0 and then connecting to my local IP address (not 127.0.0.1, but the actual address) but I didn't see any activity. I did see activity if I connected from an external machine. Then I ran tcmpdump on lo, again tried to connect and this time I saw activity. So this leads me to believe that any requests made to my own IP address locally aren't getting handled by iptables. Just for reference he's what my NAT table looks like now: Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:http redir ports 9640 REDIRECT tcp -- anywhere anywhere tcp dpt:xfer redir ports 9640 REDIRECT tcp -- anywhere anywhere tcp dpt:https redir ports 8443 Chain POSTROUTING (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination

  • Why can't I run virtualenv without root?

    - by James
    I'm trying to run virtual env and all the documentation says I don't need to run it as root (and probably shouldn't). If I run it as root, everything works. If I run it without root, I get: [stats@crunch ~]$ virtualenv env Traceback (most recent call last): File "/usr/bin/virtualenv", line 5, in from pkg_resources import load_entry_point File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in working_set.require(requires) File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: virtualenv==1.7.1.2 I believe I can change the ownership and it's the same difference, but I'd like to know why this is happening. It's a fresh CentOS 6.2 installation.

  • Is Gmail Being Blocked by my ISP (wait till you read this)?

    - by James
    This is the strangest thing I have ever encountered. I have a desktop on which I cannot access Gmail and also youtube sign in (I believe since youtube is owned by google they both use the same sign in system). So okay, maybe my ISP is blocking these for some reason or maybe my firewall is, or maybe there is something wrong with my connectivity, right? NO. On other computers that uses the same connection via a wireless router I can access both gmail and youtube sign in just fine. On this computer which doesn't have a wireless card and so I have to connect via Ethernet cable (connected to a USB converter since the Ethernet port doesn't work anymore) I can access all sites and services including things like aol and hotmail. But only when it comes to gmail, do I get complete and utter throttling. I even turned off my AV ad Firewall momentarily and no luck. The gmail ages starts to load and by mid point it just stays there loading and loading and loading... never ends. I tried everything, I reset the modem and router multiple times. I reinstalled my operating system from a vista to a windows 7 hoping a complete reinstall would solve the issue, but no luck. So can anyone for the life of them figure out why this could be? And yes, I am going to call my ISP but not to solve this issue, but to cancel them. I want to upgrade to cabel from DSL anyway. I didn't mention my ISP because I'm not sure if that is within the rules (if it's okay some one let me know and I will). P.S. All this happened one day, before gmail was perfectly accessible in this computer. I can't remember anything special that happened on that day prior to this. The only thing I can think of is, my ISP or Google itself is blocking this computer based on it's mac address, but I don't know if that's even done. Additional info: PC: Windows 7 Ultimate 32 bit Connection Type: DSL Connecting Medium: Ethernet cable via USB converter

  • Windows Home Server backup recovery missing driver for USB Device

    - by Pat James
    I'm doing a backup recovery of a Windows 7 PC from the backup on Windows Home Server. I've done this before and am accustomed to the prompt to load drivers for devices such as the NIC from a USB flash drive, which I have all loaded up with the drivers from the special folder in the WHS backup repository for this PC. My problem on this PC is that one of the drivers the recovery CD complains is missing is "USB Device", and it fails to find the drivers when I click the button to scan for and install drivers. So it seems it can't access the USB flash drive to load the other drivers. Any suggestions? I think my next step is to pull a DVD drive from another system and plug it in with a CD burned with the device drivers.

  • Google Apps Sync bloated PST file to 14GB

    - by James S
    Back story: I have Outlook connected to my Google Apps email and noticed that some mail never got migrated from my original PST file. I found some VBA code online that compares mail in different PST folders, modified it to find missing and copy those to the target folder. I ran it folder by folder and moved missing mail. Before the exercise the Google Apps PST was about ~4GB and after it was ~4.7GB. Problem: I left Outlook open so Google Sync can copy it online. 24 hours later the Google Apps PST file bloated to 14GB+ and none of the mail has been synced to the cloud. I know that there should be at most ~5GB of mail. Why is the rest of the space being taken up? Funny thing is Gmail shows 3GB as being used online. What I tried: I emptied the deleted items folder and recycling bin I've run Outlook compact PST and it didn't work. I tried SCANPST.exe on the PST and it didn't work. I re-ran compact PST and it didn't work (after SCANPST found and fixed a few errors) Any ideas out there on what caused the problem and how to solve it?

  • Recover from running "route -f"

    - by James L.
    I was trying to capture localhost traffic with Ethereal, which doesn't work without re-routing localhost traffic to your router gateway. I didn't get the route command quite right, and messed up my routing table. I typed route -f to clear the routing table and rebooted, but when I finished rebooting, the routing table wasn't restored to its original state. I didn't use the -p parameter, so none of my changes should have persisted after a reboot. What can I do to restore the routing table to its default routes?

  • How important is patch management?

    - by James Hill
    Problem I'm trying to sell the idea of organizational patch/update management and antivirus management to my superiors. Thus far, my proposition has been met with two responses: We haven't had any issues yet (I would add that we know of) We just don't think it's that big of a risk. Question Are there any resources available that can help me sell this idea? I've been told that 55-85% of all security related issues can be resolved by proper anti-virus and patch/update management but the individual that told me couldn't substantiate the claim. Can it be substantiated? Additional Information 1/5 of our computers (the ones on the building) have Windows update turned on by default and anti-virus installed. 4/5 of our computers are outside corporate and the users currently have full control over anti-virus and Windows updates (I know this is an issue, one step at a time).
