• Is it possible to record a screen-video from a VNC server?

  - by nikie

  I have a computer that's running VNC server. I would like to record a video of what's going on on this computer, if possible without installing additional software on that computer. Is there a program that can connect to the VNC server port and instead of displaying the screen save it to an (e.g. AVI) video file? Background: One of our customers sometimes has problems with the software he bought from us when he's performing a complex procedure. To help him, we offered that someone (a service technician or programmer) watches what he's doing during that procedure to find out if he's doing something wrong or if there's a bug in the software. Currently, this is done live via VNC. That has a few disadvantages: The service technician has to be in the office at the time. As the customers are in different time zones, that can be in the middle of the night. If the service technician forgets something or doesn't notice something, it's lost. There's no way to see what happened again. Only a single computer can be watched by one service technician at a time. I know I could install normal screen-grab software on the computer, but we're talking about an embedded system with limited RAM, CPU, HDD space, so installing something new is not an easy decision. And VNC is already there. I could of course open a VNC client on some office PC and capture that PC's screen, but I can only record one remote computer that way. I often have to watch up to 8 screens in parallel. (And I don't think that screen-grabbing VNC would improve image quality, either.)

• Trouble Letting Users Get to Certain Sites through Squid Proxy

  - by armani

  We have Squid running on a RHEL server. We want to block users from getting to Facebook, other than a couple specific sites, like our organization's page. Unfortunately, I can't get those specific pages unblocked without allowing ALL of Facebook through. [squid.conf] # Local users: acl local_c src 192.168.0.0/16 # HTTP & HTTPS: acl Safe_ports port 80 443 # File containing blocked sites, including Facebook: acl blocked dst_dom_regex "/etc/squid/blocked_content" # Whitelist: acl whitelist url_regex "/etc/squid/whitelist" # I do know that order matters: http_access allow local_c whitelist http_access allow local_c !blocked http_access deny all [blocked_content] .porn_site.com .porn_site_2.com [...] facebook.com [whitelist] facebook.com/pages/Our-Organization/2828242522 facebook.com/OurOrganization facebook.com/media/set/ facebook.com/photo.php www.facebook.com/OurOrganization My biggest weakness is regular expressions, so I'm not 100% sure about if this is all correct. If I remove the "!blocked" part of the http_access rule, all of Facebook works. If I remove "facebook.com" from the blocked_content file, all of Facebook works. Right now, visiting facebook.com/OurOrganization gives a "The website declined to show this webpage / HTTP 403" error in Internet Explorer, and "Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error" in Chrome. WhereGoes.com tells me the URL redirects for that URL goes like this: facebook.com/OurOrganization -- [301 Redirect] -- http://www.facebook.com/OurOrganization -- [302 Redirect] -- https://www.facebook.com/OurOrganization I tried turning up the debug traffic out of squid using "debug_options ALL,6" but I can't narrow anything down in /var/log/access.log and /var/log/cache.log. I know to issue "squid -k reconfigure" whenever I make changes to any files.

• TCP dies on a Linux laptop

  - by Roman Cheplyaka

  Once in several days I have the following problem. My laptop (Debian GNU/Linux testing) suddenly becomes unable to work with TCP connections to the internet. The following things continue to work fine: UDP (DNS), ICMP (ping) — I get instant response TCP connections to other machines in the local network (e.g. I can ssh to a neighbour laptop) everything is ok for other machines in my LAN But when I try TCP connections from my laptop, they time out (no response to SYN packets). Here's a typical curl output: % curl -v google.com * About to connect() to google.com port 80 (#0) * Trying 173.194.39.105... * Connection timed out * Trying 173.194.39.110... * Connection timed out * Trying 173.194.39.97... * Connection timed out * Trying 173.194.39.102... * Timeout * Trying 173.194.39.98... * Timeout * Trying 173.194.39.96... * Timeout * Trying 173.194.39.103... * Timeout * Trying 173.194.39.99... * Timeout * Trying 173.194.39.101... * Timeout * Trying 173.194.39.104... * Timeout * Trying 173.194.39.100... * Timeout * Trying 2a00:1450:400d:803::1009... * Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable * Success * couldn't connect to host * Closing connection #0 curl: (7) Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable Restarting the connection and/or reloading the network card kernel module doesn't help. The only thing that helps is reboot. Clearly something is wrong with my system (everything else works fine), but I have no idea what exactly. I don't know how to reproduce this, but as I said, it happens every several days. My setup is a wireless router that is connected to the ISP via PPPoE. Any advice?

• How to handle OpenVPN client as a service, when the laptop is physically on the network already?

  - by James

  The Setup I've gotten OpenVPN working on our Windows XP laptops. Users are limited, so I went ahead and set OpenVPN client to run as a service, which is great anyway because that means they are on the VPN before logging in, so login scripts work, plus we can do remote support even if the user can not log in (such as connecting via VNC or resetting passwords). It is also configured to send all traffic over the tunnel, so when, for example, they browse the internet it is just like browsing from our corporate network. The Qestion(s) So, I'm wondering how does the OpenVPN client act when the computer is already physically on the same network as the OpenVPN server? Right now, the client is configured to connect the the public dns name which will resolve to the public ip address which will NOT get reflected back to the OpenVPN server, so it is affectively blocked from connecting to the OpenVPN server while on the network. Is that a good thing? Or will it constantly try to connect, using up system resources and network resources? We will likely have hundreds of laptops regularly on the physical network with this, so it could contribute to a lot of unnecessary network chatter. Alternatively Would it be better to have the firewall reflect the port back to the OpenVPN server and let it connect? Or have our internal dns resolve the name to the private ip and allow them to connect directly? Would traffic then go over the vpn connection (which I do not want, when already on the physical network)? Or is it possible to tell it to ignore the connection when the client and server are already on the same network? TLDR What's a sane way of handling OpenVPN client running as an always-on service when the client and server will often be on the same network?

• Install mod_perl2 on Apache 2.2.14 (Ubuntu10.04)

  - by MICADO

  Hi guys, I have installed via synaptic package ibapache2-mod-perl2. I tried this line in httpd.conf: "LoadModule perl_module modules/mod_perl.so" Apache tells me when I reload the server : "[warn] module perl_module is already loaded, skipping". Well ok, but when i try to look in the browser to a repertory i don't have access .Apache send me the error : Forbidden You don't have permission to access /cgi-bin/ on this server. Apache/2.2.14 (Ubuntu) Server at 192.168.0.10 Port 90 But this should show modperl is installed and that's not the case...

• How to troubleshoot Linksys E4200 Remote Management

  - by Jordan

  My Linksys E4200 is configured for Remote Management, but the router is not accepting the connections. Here's the configuration under Administration Management Remote Management Access: Remote Management: Enabled Access via: HTTP Remote Upgrade: Disabled Allowed Remote IP Address: Any IP Address Remote Management Port: 8080 The router is setup to use 192.168.10.41 as its static Internet IP address, and 192.168.35.1 as its LAN IP address. I can access the router just fine via its LAN IP address, but I can't make a connection using http://192.168.10.41:8080. I've tried variations of the settings above (enabled HTTPS, enabled Remote Upgrade, set an IP range of 192.168.10.1-254) but nothing has worked yet. Hoping someone can at least point me in the right direction. Thanks. Update: To clarify, I have a wired router that connects straight to the T1 modem. It's configured to use 192.168.10.1-254 as its internal LAN range. The E4200 wireless router in question is on that LAN using 192.168.10.41 as its WAN IP address. The E4200's internal LAN range is 192.168.35.1-254. I'm not trying to access the E4200 from the Internet, I'm just trying to access it from its WAN IP address. Thanks.

• Firefox Does NOT get local site cookie

  - by Campo

  This is a weird one. We have a production server (Server 2008) and two staging servers (Server 2008 and Server 2003) I have sites on all of these. They all use cookies. On the Production server when browsing to our site www.supernovainteractive.com there is a cookie that detects when you visted the site and it will not refresh the logo animation (top left hand side) on clicking to another page. This works for all browsers on the production server. I’m not sure what’s going on but for some reason cookies are not working on one site in the 2008 staging server only. This is when browsing using Firefox (3.6.3) they work fine on all other browsers (IE, Chrome, Safari, Opera) In addition, the 2003 staging server works fine. You can test on the Supernova Interactive site by noticing the logo in the top left corner. It uses a cookie to detect if you’ve already seen the animation. Once you’ve seen it once, it doesn’t animate again until tomorrow. Currently, it’s animating every time. I have opened an outside facing port so others can see the issue. Http://exchange.supernova.com:10009 Any ideas on this one? Firewalls are off on the server. Notice you do not get a cookie from Exchange.supernova.com.

• Libvirt/KVM in NAT: can't access from host (and can't forward)

  - by SharkWipf

  I'm trying to set up a port forward to a KVM guest, managed through Libvirt on Debian 6. The VM is running in NAT, through the "default" network. This all runs fine, the VM has full internet connection. However, the host cannot reach the vm internally. Neither ping, nc nor nmap on the NAT network give any signs of the VM. Due to this, the normal iptables forwarding rules don't work either. $ cat /etc/debian_version 6.0.5 $ libvirtd --version libvirtd (libvirt) 0.9.11.3 $ kvm --version QEMU emulator version 1.0 (qemu-kvm-1.0+dfsg-11, Debian), Copyright (c) 2003-2008 Fabrice Bellard ifconfig: eth0 Link encap:Ethernet HWaddr 54:04:a6:f1:6f:10 inet addr:x.x.x.x Bcast:x.x.x.x Mask:255.255.255.x inet6 addr: fe80::5604:a6ff:fef1:6f10/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:118902 errors:0 dropped:0 overruns:0 frame:0 TX packets:142357 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13247173 (12.6 MiB) TX bytes:95163190 (90.7 MiB) Interrupt:28 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:230646 errors:0 dropped:0 overruns:0 frame:0 TX packets:230646 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:204577107 (195.0 MiB) TX bytes:204577107 (195.0 MiB) virbr0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:961 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:666759 (651.1 KiB) TX bytes:400701 (391.3 KiB) vnet0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet6 addr: fe80::fc54:ff:fee2:d260/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:125687 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:739803 (722.4 KiB) TX bytes:6886609 (6.5 MiB)

• Library conflict in Mac OS X

  - by Juan Medín

  I was trying to install the ImageMagick library on Mac OS X Snow Leopard, and first I tried port and, after it failed, homebrew. It updated some dependencies and installed ImageMagick without problems. So far so good. The problem came when I ran Apache. I got the following error in the system log: 07/04/11 12:55:15 org.apache.httpd[41841] httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /opt/local/apache2/modules/libphp5.so into server: dlopen(/opt/local/apache2/modules/libphp5.so, 10): Library not loaded: /opt/local/lib/libpng12.0.dylib\n Referenced from: /opt/local/apache2/modules/libphp5.so\n Reason: image not found I checked the /opt/local/lib and surprise! I don't have the libpng12.0 but the libpng14.0. So, as far as I can tell, something went wrong installing the ImageMagick library. Now, I can't find a way to rollback to the previous libraries, other than copying them from the backup. Do you know if is there a way to recover the previous state or reinstall Apache? Or is this just a corrupt state and I must reinstall OS X?

• Redis connection issue

  - by mre

  We are currently experiencing a lot of Redis errors with the message Unable to connect: read error on connection, trying next server We run Redis on FreeBSD using PHP Redis and we have a hard time reproducing the error on Ubuntu so this might be a hint. There's a long-running issue on that topic on github. Basically we get a socket from the operating system with a call to connect(host, port, timeout) in phpredis, but when we do a select(db_index) afterwards, we get an exception. Could there be an issue with persistance? I assume that connect does nothing in the background and select tries to access the connection, which is actually closed. We don't run into a timeout. We tried tuning TIME_WAIT without success. Any other ideas on where the problem might come from? What is the best way to track the issue down? dtrace maybe? Update We are currently looking into our BGSAVE settings. Interestingly it takes half a second and more to create a fork for the process which regularly writes the data to disk (persistence) and maybe redis can't respond to connect() requests during that timespan.

• Network switches for LAN party

  - by guywhoneedsahand

  I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

• Stack Managed Switches over a distance

  - by Joel Coel

  We have several buildings with stacked switches, where the distance between the stacked units is considerable... separate floors, or at opposite ends of a hallway. They are 3Com switches that stack using cat6 cabling. These switches are coming up on 12 years old now, and as I look around at replacements it seems no one supports this scenario any more. Stacking switches want to use fiber links (it more for me to run and terminate the fiber stacking cables than to purchase the switch) or other custom cables that seem only intended to jump up to the next unit in a rack. What have others done to support stacking over a distance? I'm considering breaking up the stacked switches into separate managed entities and just bridging from the root switch in the buildings, but I'd really like to avoid that for what I hope are obvious reason. The closest thing I've found are from netgear that use hdmi cables for the stacking connection... I could try to support that by running an additional cat6 line and re-terminating both links into a single hdmi port, but I have concerns over that approach as well.

• NAT via iptables and virtual interface

  - by Alex

  I'm trying to implement the following scenario: One VM-host, multiple guest VMs, each one gets its own IP-address (and domain). Our server has only one physical interface, so the intended use is to add virtual interfaces on eth0. To complicate our situation the provider uses port-security on their switches, so I can't run the guest interfaces in bridged mode, because then the switch detects a "spoofed" MAC-address and kills the interface (permanently, forcing me to call the support, which I'm sure will get them a little bit angry the third time ;) ). My first guess was to use iptables and NAT to forward all packages from one virtual interface to another one, but iptables doesn't seem to like virtual interfaces (at least I can't get it to work properly). So my second guess is to use the source IP of the packages to the public interface. Let's assume libvirt creates a virbr0-network with 192.168.100.0/24 and the guest uses 192.168.100.2 as IP-address. This is what I tried to use: iptables -t nat -I PREROUTING --src public_ip_on_eth0:0 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.2:80 That doesn't give me the intended results either (accessing the server times out). Is there a way to do what I'm trying to do, or even to route all traffic to a certain IP on a virtual interface to the VM's device?

• SSH from ubuntu server to Windows 2008 repeatedly asks for password

• Window 7 image in vmware will allow network connection out but not http

  - by Ormis

  I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I initially asked this on stackoverflow and now my eyes are now opened up to superuser. Thank you for any help you can provide.

• Serve web application error messages from Http server

  - by licorna

  I have nginx as a http server with tomcat as a backend (using proxy_pass). It works great but I want to define my own error pages (404, 500, etc.) and that they are served by nginx and not tomcat. For example I have the following resource: https://domain.com/resource which doesn't exist. If I [GET] that URL then I get a Not Found message from Tomcat and not from nginx. What I want is that every time Tomcat responds with a 404 (or any other error message) nginx sends itself a message to the user: some html file accessible by nginx. The way I have my nginx server configured is very easy, just: location / { proxy_pass http://localhost:8080/<webapp-name>/; } And I've configured port 8080, which is tomcat, as not accessible from outside this machine. I don't think that using different location directives in nginx configuration will work, because there are some resources that depend on the URL: https://domain.com/customer/<non-existent-customer-name>/[GET] Will always return 404 (or any other error message), while: https://domain.com/customer/<existent-customer>/[GET] Will return anything different from 404 (the customer exists). Is there any way of serving Tomcat (Application Server) error messages with Nginx (http Server)? To check the message sent by the proxy_pass directive and act upon it?

• USB Device Not Recognized (Mac)

  - by Nargis

  Fortunately, my Mac-pro also made one of my USB storage devices inoperable. My data loss in that USB device but such as another USB device and USB keyboard are unaffected. I have heard that my friend usually trigger this problem by having at least two devices plugged in - typically thumb drives/USB flash drives, and then once a second flash drive is plugged in that become unrecognized. I have only two USB ports and first I think port loose when I connect two USB devices. But later I found these hidden files (“.Spotlight-V100”, “.TemporaryItems”, “.Trashes”, and “._.Trashes”) are created by Mac OS. And before unrecognized that USB device I have deleted these files and my friend had also done the same action. Now I don’t want to test for next USB device to become unrecognized and I won’t deleted any hidden system file inside the flash drives. But I really want to know why these problems happened. Can I delete these hidden files when I only connect to virtual machine (Vista), because I used to delete all useless hidden files from USB flash drives? Any suggestions or thoughts to prevent this or alternative suggestions to fix the problem that take lossless would be much appreciated.

• RabbitMQ Management console not working

  - by rrejc

  I have started with RabbitMQ. I have a (windows) machine on which I installed two RabbitMQ nodes as a service - I have choose the nodename, port and service name for each of them. The services are running normally (i see that they are listening in a netstat-a). I have also installed management plugin with "rabbitmq-plugins enable rabbitmq_management" and restarted both services. But the plugin isn't running - I dont see it listening in a netstat and I can't connect to the management console via browser. Any idea what could be wrong? Is there any log to see what is goind on?

• gitweb refusing to blame

  I'm attempting to get gitweb (git 1.8.4.2, via git instaweb) in a project dir on my Debian server to offer blame views. In my /etc/gitweb.conf: … # default logo, favicon, etc. settings $feature{'blame'}{'default'} = [1]; $feature{'pickaxe'}{'default'} = [1]; $feature{'snapshot'}{'default'} = ['tgz', 'txz', 'zip']; $feature{'highlight'}{'default'} = [1]; $feature{'pathinfo'}{'default'} = [1]; In my global config file: [gitweb] blame = true snapshot = tgz, txz, zip patches = 256 avatar = gravatar [instaweb] local = false httpd = apache2 -f port = 4321 In my project's .git/config file: [gitweb] blame = true And yet, when I try to load a git blame view (via hand-modifying the URL to http://myserversip:4321/?p=.git;a=blame;f=Tests/InchCoordProxyTests.m;h=b4b2…;hb=53b4, since blame action links don't show up): Doing a quick search for “Blame view not allowed” in the gitweb.cgi source reveals plainly that the gitweb_check_feature('blame') conditional is failing. What am I doing wrong? Or, is there a way to verbosely print out why gitweb is doing what it's doing (e.g. which config files were read, which settings were loaded from each file, etc.)?

• Why are SIP calls via my server silent?

  - by Archcode

  I have FreeSWITCH SIP server up and running. It has public IP and sits behind 1-to-1 NAT (it's Amazon EC2 instance actually). I can connect to it, make a call to other endpoint (namely, my android device to my pc and vice versa) and signals are send with no problems (call, answer, hangup, etc). Unfortunately, and what drives me crazy, that's all: no audio gets through, no video either. Server does not throw errors, it reports many retransmission though, looks like this: switch_rtp.c:915 [ zrtp engine]: WARNING! HELLO Max retransmissions count reached (20 retries). ID=15 Codecs are set up correctly (same config worked locally on my LAN). NAT/firewall on client side may be a problem, signals do get through (perhaps due to fixed port, data streaming runs on random one, that is currently my best bet). STUN/TURN/ICE setting on client seem to have no effect. Endpoints sit behind symmetric NAT. On server there are no iptables rules, security group is set as suggested there: http://wiki.freeswitch.org/wiki/Firewall Help, please. How to make it work or at least diagnose what's wrong?

• Trying to Set up SMTP Server on WIndows Server 2012

  - by datc

  I'm working on a website, and I need to test the functionality of sending email messages from ASP.NET, something like this: Dim msg As New MailMessage("email1", "email2") msg.Subject = "Subject"<br> msg.IsBodyHtml = True<br> msg.Body = "Click <a href='site'>here</a>." Dim client As SmtpClient = New SmtpClient() client.Host = "My-Server"<br> client.Port = 25<br> client.DeliveryMethod = SmtpDeliveryMethod.Network<br> client.Send(msg) This is running from a Windows 8 workstation. I've installed SMTP server on my Windows Server 2012 machine. The mail shows up in the mailroot/Queue folder and sits there, eventually getting deposited into Badmail. Now I have AT&T U-verse at home, and a few devices connected to the gateway, including let's call it "My-Server." When I run SmtpDiag from say, datc@... to [email protected] I get SOA serial number match passed, Local DNS (99-135-60-233.lightspeed.bcvloh.sbcglobal.net) & Remote DNS (hotmail.com) tests *not* passed, and ultimately, Connecting to the server failed. Error: 10060. Failed to submit mail to mx2.hotmail.com error. When I set My-Server's IP to static and equal to the external IP, 99.135.60.233, and again run SmtpDiag, I get SOA, Local DNS, and Remote DNS tests passed, but the same 10060 error. Same for yahoo.com, gmail.com, and so forth. Is it my ISP's job to fix this? Some PTR record missing somewhere? Is it at all possible to have a home-based SMTP server? All I want is to test my email code. Perhaps, my IP address is just not "trusted" somehow. Thanks.

• allow spoofing when using tun

  - by Johnny

  I have a working openvpn setup with a server and a number of clients. How would i go around allowing IP spoofing through the openvpn server? (to demonstrate security concepts)? A normal ping from client to server goes through all right: root@client: hping3 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes len=40 ip=10.8.0.1 ttl=64 DF id=0 sport=0 flags=RA seq=0 win=0 rtt=124.7 ms root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes 10:17:51.734167 IP 10.8.0.6.2146 > 10.8.0.1.0: Flags [], win 512, length 0 But when spoofing a packet, it does not arrive at the openvpn server: root@client: hping3 -a 10.0.8.120 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes My current config files server.conf local X.Y.Z.P port 80 proto tcp dev tun ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1 bypass-dhcp" keepalive 10 120 comp-lzo persist-key persist-tun persist-local-ip status openvpn-status.log verb 3 client.conf client dev tun proto tcp remote MYHOST..amazonaws.com 80 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3

• Cloning a git repository from a machine running OS X

  - by Mike

  Hi folks, I'm trying to host a git repository from my home OS X machine, and I'm stuck on the last step of cloning the repository from a remote system. Here's what I've done so far: On the OS X (10.6.6) machine (heretofore dubbed the "server") I created a new admin user Logged into the new user's account Installed git Created an empty git repository via "git init" Turned on remote login Set port mapping on my router (airport extreme) to send ssh traffic to the server Added a ".ssh" directory to the user's home directory From the remote machine (also an OS X 10.6.6 machine), I sent that machine's public key to the server using scp and the login credentials of the user created in step 1 To test that the server would use the remote machine's public key, I ssh'd to the server using the username of the user created in step 1 and indeed was able to connect successfully without being asked for a password I installed git on the remote machine From the remote machine I attempted to "git clone ssh://[email protected]:myrepo" (where "user", "my.server.address", and "myrepo" are all replaced by the actual username, server address and repo folder name, respectively) However, every time I try the command in step 11, I get asked to confirm the server's RSA fingerprint, then I'm asked for a password, but the password for the user I set up for that machine never works. Any advice on how to make this work would be greatly appreciated!

• Packet flooding while configuring a Debian L2TP/IPSec client?

  - by Joseph B.

  I'm currently at my wits end trying to configure an L2TP over IPSec VPN connection on my Debian using openswan and xl2tp box connecting to a server of unknown configuration. I've managed to successfully establish the connection and everything appears to be working well until I attempt to set the VPN connection as my default route, at which point I see a massive flood of packets simultaneously being transmitted (on the tune of ~1.5 GB in about 2min) until the server drops my connection. Prior to this network traffic on all my interfaces is minimal. According to iftop the majority of this traffic appears to be coming out of port 12, although I can't seem to figure out how to finger a specific process. If I instead just route traffic destined for 74.0.0.0/8 through it I'm able to access Google's servers through the VPN without issue. My xl2tp.conf file is: [lac vpn-nl] lns = example.vpn.com name = myusername pppoptfile = /etc/ppp/options.l2tpd.client My options.l2tpd.client file is: ipcp-accept-local ipcp-accept-remote refuse-eap require-mschap-v2 noccp noauth idle 1800 mtu 1410 mru 1410 usepeerdns lock name myusername password mypassword connect-delay 5000 And my routing table looks like: Destination Gateway Genmask Flags Metric Ref Use Iface 10.5.2.1 * 255.255.255.255 UH 0 0 0 ppp0 10.0.50.0 * 255.255.255.0 U 0 0 0 eth0 10.50.0.0 * 255.255.0.0 U 0 0 0 eth0 10.0.0.0 * 255.255.0.0 U 0 0 0 eth0 192.168.0.0 * 255.255.0.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default * 0.0.0.0 U 0 0 0 ppp0 I'm seeing absolutely nothing in auth.log and syslog during this time and can't seem to find any other log files it might be writing to. Any suggestions would be appreciated!
