  • How would you secure a home router with a self-signed certificate?

    - by jldugger
    littleblackbox is publishing "private keys" that are accessible on publicly available firmwares. Debian calls these "snake-oil" certs. Most of these routers are securing their HTTPS certs with these, and as I think about it, I've never seen one of these internal admin websites with certs that wasn't self signed. Given a webserver on IP 192.168.1.1, how do you secure it to the point that Firefox doesn't offer warnings (and is still secured)?

  • Recommended method for routing www to zone apex (naked domain) using AWS Route 53

    - by Dan Christian
    In my AWS Route 53 control panel I simply have 2 A records currently set up for the 'www' and the 'non www' names. Both point to the Elastic IP address associated with my EC2 Instance. This works well and my website is available at both variations but I really want all 'www' to route to the 'non www'. What is the reccomened method, using AWS Route 53, for routing all traffic that comes to... www.example.com to example.com

  • route http and ssh traffic normally, everything else via vpn tunnel

    - by Normadize
    I've read quite a bit and am close, I feel, and I'm pulling my hair out ... please help! I have an OpenVPN cliend whose server sets local routes and also changes the default gw (I know I can prevent that with --route-nopull). I'd like to have all outgoing http and ssh traffic via the local gw, and everything else via the vpn. Local IP is 192.168.1.6/24, gw 192.168.1.1. OpenVPN local IP is 10.102.1.6/32, gw 192.168.1.5 OpenVPN server is at {OPENVPN_SERVER_IP} Here's the route table after openvpn connection: # ip route show table main 0.0.0.0/1 via 10.102.1.5 dev tun0 default via 192.168.1.1 dev eth0 proto static 10.102.1.1 via 10.102.1.5 dev tun0 10.102.1.5 dev tun0 proto kernel scope link src 10.102.1.6 {OPENVPN_SERVER_IP} via 192.168.1.1 dev eth0 128.0.0.0/1 via 10.102.1.5 dev tun0 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 1 This makes all packets go via to the VPN tunnel except those destined for 192.168.1.0/24. Doing wget -qO- http://echoip.org shows the vpn server's address, as expected, the packets have 10.102.1.6 as source address (the vpn local ip), and are routed via tun0 ... as reported by tcpdump -i tun0 (tcpdump -i eth0 sees none of this traffic). What I tried was: create a 2nd routing table holding the 192.168.1.6/24 routing info (copied from the main table above) add an iptables -t mangle -I PREROUTING rule to mark packets destined for port 80 add an ip rule to match on the mangled packet and point it to the 2nd routing table add an ip rule for to 192.168.1.6 and from 192.168.1.6 to point to the 2nd routing table (though this is superfluous) changed the ipv4 filter validation to none in net.ipv4.conf.tun0.rp_filter=0 and net.ipv4.conf.eth0.rp_filter=0 I also tried an iptables mangle output rule, iptables nat prerouting rule. It still fails and I'm not sure what I'm missing: iptables mangle prerouting: packet still goes via vpn iptables mangle output: packet times out Is it not the case that to achieve what I want, then when doing wget http://echoip.org I should change the packet's source address to 192.168.1.6 before routing it off? But if I do that, the response from the http server would be routed back to 192.168.1.6 and wget would not see it as it is still bound to tun0 (the vpn interface)? Can a kind soul please help? What commands would you execute after the openvpn connects to achieve what I want? Looking forward to hair regrowth ...

  • How to check properties of an audio [closed]

    - by Ashni Goyal
    Possible Duplicate: Tool to view video/audio file information Soundeffect class in WP7 requires following properties of the .wav file. The Stream object must point to the head of a valid PCM wave file. Also, this wave file must be in the RIFF bitstream format. The audio format has the following restrictions: Must be a PCM wave file Can only be mono or stereo Must be 8 or 16 bit Sample rate must be between 8,000 Hz and 48,000 Hz How can we check these properties for a given audio ?

  • Linux bonded Interfaces hanging periodically

    - by David
    I've several hosts that are showing problems with connectivity. When working from the command line, for example, typing is frozen for a second or so, then recovers - then it does it again. The most egregious example host would freeze (input) for 15-30 seconds, then recover and go out 5 seconds later. Switching cables didn't do anything - but removing one of the physical cables caused everything to clear up instantly (which why I think this is a network problem). Looking at the network I couldn't see any packets floating that would explain this. These ethernet interfaces (Gigabit Dell) were working normally previously, but since we moved the systems - and put them on a new set of switches - this has been a problem on multiple theoretically identically-configured hosts. The original switches were an HP Procurve 1810-24G and an HP Procurve 1800-24G connected with LLDP; the new switches are both Cisco SG 200-26, which I understand are rebranded Linksys switches. Is this caused by a problem with the switches? Is it the switch configurations? Are the Cisco switches incapable of handling this? I don't see where the configuration is located; I searched the usual /etc/sysconfig/network/devices but there's nothing in there about options (like mii polling) and nothing about the method of balancing the two. Searching scripts, I can't find anything in /etc/init.d/network either. The hosts are almost all Red Hat Enterprise Linux 5.x systems (5.6, 5.7) but some are Ubuntu Server 10.04.3 Lucid Lynx. I need help with both if it comes to that. UPDATE: We're also seeing some problems with servers on the original switches. The HP switches and the Cisco switches are also interconnected (temporarily); there is a cable run from one switch to the next. Pings on any of these hosts show about one ICMP packet out of every 5-6 getting dropped (timed out). Could there be an interaction between the two switches? Oh, and the hosts are using bonding with Balance-RR as the method.

  • Exchange not delivering the mail

    - by wolfvilleian
    I'm having an issue where my Exchange Edge Transport server receives mail (found in logs) and then it vanishes, never ending up in the users mailbox, I have a edge subscription setup between it and the main Exchange server, how can I go about tracing the message to figure out what is broken? I also have found records of the message in the logs on the main Exchange server. Thanks a ton for any help Edit: If I change port 25 on my main router to point to the main exchange server as opposed to the Edge Transport, email comes through fine form external domains and delivered in the correct mailbox

  • Can someone implement LVM on an existing single-hard disk system ?

    - by jfmessier
    I am using SuSE Linux (10) and I am considering expanding the available disk, without resizing an existing partition (which is not easy to do on a VM). Instead, I want to create another virtual disk, and add it in a new LVM volume, which would include the existing disk, and this new one, in a seamless single mount point. We are using VMware vServer 4, under Lab Manager and Virtual Centre. Does SuSE support LVM in version 10 ? Thanks :-)

  • Is it possible to add wildcard serveralias to virtualhost without modifying httpd.conf manually?

    - by Favourite Chigozie Onwuemene
    Is it possible to add wildcard serveralias (example: *.somesite.com) in an apache server without modifying httpd.conf manually? I use a DNS different from my hosting server and i have added asterisk A record to my DNS to point all request like (test.somesite.com,test2.somesite.com) to my hosting servers IP, but i don't see anyway of adding asterisk serveraliases to apache httpd.conf file in my cpanel. Pls is there a solution?

  • circumstances where software change leads to device damage

    - by nerorevenge
    Recently I changed a friend's OS from a really virus filled windows 7 to Ubuntu ..but kept changing os's because lsusb wouldn't detect the camera.But after coming back to windows, the camera wasn't detected, though I must point out the device driver for the camera was never found. The Sony 'technician' told me that that since the dev-manager of windows 7 couldn't detect the camera , irregardless of whether the device driver was installed, the software change must have damaged the hardware. I was wondering if there is any truth to it.

  • How does Bittorrent work?

    - by mumtaz
    I want to learn more about the bittorrent way of file sharing. I am a technically advanced user (programmer), so technically advanced material is no problem, but it should be concise and to the point. I need a good resource book/web which explains the overall bittorrent architecture. I am not interested in details, just the overall architecture and the terminology like seeds, peers, etc. Any suggestions?

  • Redirection and SSL

    - by Kobus Myburgh
    I hope I am asking this at the correct forum. I have a client from whom I have developed a PHP based Facebook project, who is hosting their site on IIS with ASP and no access to PHP, so they have created a sub domain to point to my server to host the site. I have an SSL on www.mydomain.com, but their sub domain does not have SSL (app.theirdomain.com). Would redirection from their side be possible to SSL on my side so that the FB app works?

  • If my Remote Desktop Connection Broker server goes down, can users still access my two Terminal Servers?

    - by Frank Owen
    I would like to setup the Remote Desktop Connection Broker to allow better load balancing of the two terminal servers we have as well as allowing the user to re-establish to the correct server if they get disconnected. My worry is, if I set this up and the server this service is running goes down, does the terminal server stop accepting connections or will they just lose the benefit of having RDCB turned on? I don't want to add another point of failure in this equation unless I have to.

  • How to serve a webpage on connection to WiFi network

    - by samwatt
    Hi, I would like to be able to serve a local webpage (on a LAN) when someone connects to a WiFi network. This happens quite often in libraries, cafes etc, so i'm sure it can be done, but I have no idea how and can't seem to find much through searching the web. That, and my very limited networking knowledge means I'm hoping you guys can point me in the right direction. Many thanks!

  • Exchange 2003 mailbox migrated to 2010 not showing up in Address book

    - by TJ
    I have migrated about 45 mailboxes at this point from our single instance of Exchange 2003 to a High Availability Exchange 2010 environment successfully. However one mailbox moved successfully and the user is able to send and receive e-mail internally and externally with no problems but they do not show up in the Global Address List. The OAB is owned by an Exchange 2010 mailbox server. What am I missing?

  • How remove/de-index a page from Google?

    - by Jason
    On the results page when I Google "e-luminate", the 3rd and 4th link seems to point to specific directory deep within the folders which stores the images. How can I get rid of these 2 results from Google search results? How can I get Google to de-index it? I checked on the server and the folders did not seem different from other folders but these 2 paths seems to get indexed by Google. Thank you.

  • High CPU usage - symptoms moving from server to server after bouncing

    - by grt3kl
    First off, I apologize if I didn't include enough information to properly troubleshoot this issue. This sort of thing isn't my specialty, so it is a learning process. If there's something I need to provide, please let me know and I'll be happy to do what I can. The images associated with my question are at the bottom of this post. We are dealing with a clustered environment of four WebLogic 9.2 Java application servers. The cluster utilizes a round-robin load algorithm. Other details include: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04) BEA JRockit(R) (build R27.4.0-90_CR352234-91983-1.5.0_12-20071115-1605-linux-x86_64, compiled mode) Basically, I started looking at the servers' performance because our customers are seeing lots of lag at various times of the day. Our servers should easily handle the loads they are given, so it's not clear what's going on. Using HP Performance Manager, I generated some graphs that indicate that the CPU usage is completely out of whack. It seems that, at any given point, one or more of the servers has a CPU utilization of over 50%. I know this isn't particularly high, but I would say it is a red flag based on the CPU utilization of the other servers in the WebLogic cluster. Interesting things to note: The high CPU utilization was occurring only on server02 for several weeks. The server crashed (extremely rare; we are not sure if it's related to this) and upon starting it back up, the CPU utilization was normal on all 4 servers. We restarted all 4 managed servers and the application server (on server01) yesterday, on 2/28. As you can see, server03 and server04 picked up the behavior that was seen on server02 before. The CPU utilization is a Java process owned by the application user (appown). The number of transactions is consistent across all servers. It doesn't seem like any one server is actually handling more than another. If anyone has any ideas or can at least point me in the right direction, that would be great. Again, please let me know if there is any additional information I should post. Thanks!
