• ICMP Redirect Theory VS. Application

  - by joeqwerty

  I'm trying to watch ICMP redirects in a lab using Cisco Packet Tracer (version 5.3.2) and I'm not seeing them, which leads me to believe that either my lab configuration isn't correct or my understanding of ICMP redirects isn't correct or that Packet Tracer doesn't support/use ICMP redirects. Here's what I believe to be true regarding ICMP redirects: Routers send ICMP redirects when all of these conditions are met: The interface on which the packet comes into the router is the same interface on which the packet gets routed out. The subnet or network of the source IP address is on the same subnet or network of the next-hop IP address of the routed packet. The datagram is not source-routed. The router kernel is configured to send redirects. I have the lab set up in Cisco Packet Tracer as displayed in the image and would expect to see an ICMP redirect from Router1 when pinging from PC1 to PC3. I'm not seeing the ICMP redirect and it looks like Router1 is actually routing all of the packets via Router2. I have IP ICMP debugging enabled on Router1 (and Router2) and I'm not seeing any ICMP redirect activity in either console. I'm also not seeing a route to the PC3 network in the routing table on PC1, which I think confirms that the ICMP redirect is not occurring. I'm using only static routing on Routers 1 and 2. Is my understanding of ICMP redirects incorrect, or is there a problem with my lab configuration or does Packet Tracer not support/use ICMP redirects?

• Iverter, inverter cable, or a display cable?

  - by krebshack

  I was recently hired at a small repair shop. I work indoors while my boss does on site calls for small businesses. I have to troubleshoot and fix laptop screens a few times a week and this is why I'm posting this question. I'm having trouble figuring out how to stream line the troubleshooting process. For example, how do I determine whether the inverter is broken while also determining that the inverter cable is not. How can I quickly decide that the inverter cable is broken while knowing that the inverter is most likely not broke. Or how do I know that it's just the display cable? It seems like this is a good way to approach things: "It could be the inverter, backlight, or the LCD panel itself. Backlight failure is usually hinted at by a pink hue to everything. Inverter failure usually results in the dimming of images on the screen to the point where the backlight is not even on (the inverter provides power to the backlight)" Source. While remembering that things "like flickering, screen freeze in dark image and [a] corner starts to get brighter" point to a "failure in the LCD panel itself, though it could just as easily be a loose data cable connected to the back of the LCD." Source. In short, I'm soliciting advice that anyone might have on how to quickly make the best decision about what's causing problems with laptops display. Thank you.

• Remote Desktop to Server 2008R2 fails from one particular Win7 client

  - by Jesse McGrew

  I have a VPS running Windows Web Server 2008 R2. I'm able to connect using Remote Desktop from my home PC (Windows 7), personal laptop (Windows 7), and work laptop (Windows XP). However, I cannot connect from my work PC (Windows 7). I receive the error "The logon attempt failed" in the RDP client, and the server event log shows "An account failed to log on" with this explanation: Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: username Account Domain: hostname Failure Information: Failure Reason: Unknown user name or bad password.

The server is part of a domain but my account is local, so I'm logging in using a username of the form hostname\username. None of the clients are part of a domain. The server uses a self-signed certificate, and connecting from home I get a warning about that, but connecting from work I just get the logon error.

• Issue configuring Oracle database for SSL

• rpm build from src file

  - by danielrutledge

  Hi all, I'm trying to build from a *.src.rpm file on FC 12 in such a way that the files are distributed a across my system as they would with a normal binary build (in this case, *.h files end up in /usr/include).

• MS SQL - Problem running SQL Server Agent Job via service account credentials

  - by molecule

  There are 5 steps in this job. First job is an SSIS Package store, second to fifth are file system jobs. We configured all jobs to use Windows Authentication. Under Run As, we specified a user account which was created under SecurityCredentials and SQL Server AgentProxiesSSIS Package execution. The job runs without any problems with this user account. We then proceeded to configure the job to use a service account instead. Service account was specified under SecurityCredentials and SQL Server AgentProxiesSSIS Package Execution.

• Apache Caching and Expires configuration

  - by mcondiff

  I'm looking for a best possible caching/expires configuration for my specific situation. I realize that some sites have advocated turning etags off: Header unset ETag, FileETag None I know that I should use either Expires or Cache-Control. In additions, I know that I should use either Last-modified or ETAGs (Per ySlow docs). I inherited a clients server that uses the following in .htaccess: <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf|xml|txt|html|htm)$"> Header set Cache-Control "max-age=172800, public, must-revalidate" </FilesMatch> With this server I am not going to be able to rely on staff to rename images, css and js in web applications so I do not want to set the expires far in the future without knowing (with a good certainty) that "most/all" browsers will check to see if content has changed. What I do not want to happen is someone call me and say the website is broken because they replaced an image and it's not showing up. But I do want to take the most advantage I can with caching and expires while still maintaining that mostly all browsers will check with the server to see if components have changed. I have access to both the .htaccess and apache .conf file and it is a single server, the content is not deployed on multiple servers. What would be the best .htaccess or .conf configuration for me to achieve my goals for this clients server? Thanks for your help

• IPMI not fucntioning with Network Bonding

  - by muhammed sameer

  Hey, I am having problems with running IPMI on my servers that have network bonding enabled. Platform: CentOS release 5.3 (Final) Kernel: 2.6.18-92.el5 64bit Dell PowerEdge 1950 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet I have bonded the interface eth0 and eth1 as active passive, with eth0 as the active interface, below is conf description from /proc Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 30 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:22:19:56:b9:cd Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:22:19:56:b9:cf My IPMI device is as follows IPMI Device Information Interface Type: KCS (Keyboard Control Style) Specification Version: 2.0 I2C Slave Address: 0x10 NV Storage Device: Not Present Base Address: 0x0000000000000CA8 (I/O) Register Spacing: 32-bit Boundaries I Have used openIPMI as well as freeipmi both to control the chassis via the IPMI card, but on servers which have bonding enabled, the command times out, below is the full run of the command with debug info. ipmi_lan_send_cmd:opened=[0], open=[4482848] IPMI LAN host 70.87.28.115 port 623 Sending IPMI/RMCP presence ping packet ipmi_lan_send_cmd:opened=[1], open=[4482848] No response from remote controller Get Auth Capabilities command failed ipmi_lan_send_cmd:opened=[1], open=[4482848] No response from remote controller Get Auth Capabilities command failed Error: Unable to establish LAN session Failed to open LAN interface Unable to get Chassis Power Status On the other hand I configured IPMI on a box with the same specs as mentioned above without bonding and IPMI works perfectly. Has anyone faced this problem with IPMI + Bonding ? I would be thankful is someone helps circumvent this issue. Muhammed Sameer

• puppet cert mismatch in ec2

  - by Stick

  I'm setting up a puppetmaster (2.7.6) in ec2 via gems (on rhel6) and I'm running into problems with the cert names and getting the master able to talk to itself. my puppet.conf looks like this: [main] logdir = /var/log/puppet rundir = /var/run/puppet vardir = /var/lib/puppet ssldir = $vardir/ssl pluginsync = true environment = production report = true certname = master When I start the puppetmaster process the ssl directory looks like: ssl/private_keys/master.pem ssl/crl.pem ssl/public_keys/master.pem ssl/ca/ca_crl.pem ssl/ca/signed/master.pem ssl/ca/ca_crt.pem ssl/ca/ca_pub.pem ssl/ca/ca_key.pem ssl/certs/ca.pem ssl/certs/master.pem I have an /etc/hosts entry on the box to point the 'puppet' hostname to localhost so that I don't have to change the 'server' option. When I run the agent I get the following: # puppet agent --test info: Retrieving plugin err: /File[/var/lib/puppet/lib]: Failed to generate additional resources using 'eval_generate: Server hostname 'puppet' did not match server certificate; expected master err: /File[/var/lib/puppet/lib]: Could not evaluate: Server hostname 'puppet' did not match server certificate; expected master Could not retrieve file metadata for puppet://puppet/plugins: Server hostname 'puppet' did not match server certificate; expected master err: Could not retrieve catalog from remote server: Server hostname 'puppet' did not match server certificate; expected master warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run err: Could not send report: Server hostname 'puppet' did not match server certificate; expected master If I specify the certname as the server (with corresponding hosts entry) I get: # puppet agent --test --server master info: Retrieving plugin err: /File[/var/lib/puppet/lib]: Could not evaluate: Could not retrieve information from environment production source(s) puppet://master/plugins info: Caching catalog for master info: Applying configuration version '1321805956' notice: Finished catalog run in 0.05 seconds Which is success of a sort, that source error will bite me later when I'm applying manifests. I've tried a couple of other variations with using the ec2 private hostname and gotten mixed results. I'd like to avoid setting server = 'x' and use dns/hosts to control what 'puppet' resolves to in order to decide which server (plays easier with availability zones, etc)

• Low CPU performance with low usage and clock - Windows 8.1

  - by Daniele

  I recently deleted everything from my PC and reinstalled Windows 8.1 from scratch. When I first booted into Windows everything was extremely slow though the CPU usage was very low (about 1%). After installing some drivers the problem seemed to be solved, I was able to use my PC normally. Today I installed a game and I noticed a strange behavior: the game was playable but the performance worsened more and more in the time. This is the situation BEFORE opening the game (normal): This is AFTER some minutes inside the game (low CPU usage and clock): Some information about my system: PC: Sony Vaio S13 (SVS13A1C5E) OS: Windows 8.1 CPU: Intel Core i7-3520M 2.90GHz GPU(1): Intel HD Graphics 4000 GPU(2): NVIDIA GeForce GT 640M LE I tried searching for new drivers and other solutions but noting worked and I don't know what is the cause. I did not checked the temperatures but the fans are not running fast and the PC does not look overheated. Update: Max CPU Temp: 66°C, Max GPU Temp: 61°C The strange thing is that the GPU load is 99% (GPU-Z) and the fan is almost silent. Update 2: I had troubles with Sony Vaio software, I can't get the FN keys and the STAMINA/SPEED switch to work (it is a physical switch to enable/disable the Nvidia card and change the Power Profile). I'm saying this because I remember that before reinstalling Windows there was an option in the Vaio Control Center (now it is not there anymore) that allowed me to choose from something like "priority to performance (ventilation)" or "priority to silence". The current behavior looks like a "priority to silence", but I can't get the stamina-speed switch to work and so I don't see similar oprions in the Vaio Control Center. I don't know if the problem is related to this.

• Network monitoring tools with API features

  - by Kev

  We use ks-soft's Advanced Hostmonitor package to monitor around 2000 items on our network. We think it's great, the chap that supports it is fantastic, the product is fast, stable and mature but I feel as as we grow as a company it's beginning to show some friction points in the area of integration with our back office admin systems. One of the things we'd like to do is be able to add new tests to whatever monitoring tool we use via an API. For example, when orders for servers come from our retail interface, the server gets built automatically, and as part of the automated build process we'd like to automatically add new tests to the network monitoring systems. Hostmonitor has some support for this via a feature called HM Script but we're starting to encounter some speedbumps - we can't add new operators/users we can't define new "Action Profiles" - these are the actions to be taken when a test goes good or bad. What we love about hostmonitor though are the Action Profiles. For example if a Windows IIS box goes bad our action profile for a bad test does something like: Check host again (one time) Wait another 30 seconds then test again Try restart app pool on remote machine (up to two times) Send an email to ops about the restart failure Try restarting IIS on remote machine (up to four times) Page duty admin (up to 5 times - stops after duty admin ACKS alert) Page backup duty admin (5 times - stops after duty admin ACKS alert) I'm starting to look around at other network monitoring tools and I'm looking for: a comprehensive API to be able to add/remove/control tests/test "action profiles"/operators (not just plugins, we need control and admin interfaces) the ability to have quite detailed action/escalation profiles (and define these via an API) I've looked at Nagios and Icinga but Ican't seem to glean from their documentation whether we could have these features or not, or if we could, how much work would be involved to implement/customise. Can anyone provide any advice, guidance or experiences?

• socket problem with MySQL

  - by Hristo

  This is a recent problem... MySQL was working and a couple of days ago I must have done something. I deleted MySQL and tried reinstalling using the .dmg file. The mysql.sock file never gets created and I get the following error messages: Hristo$ mysql Enter password: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) I also tried stopping Apache and installing but Apache gave me an error... I don't know if this is good or bad: Hristo$ sudo apachectl stop launchctl: Error unloading: org.apache.httpd I tried the MacPorts installation as well but the socket file still didn't get created. I don't really know what to do and I don't want to reinstall Snow Leopard and start from scratch :/ I also tried installing the 32-bit version and same deal. No luck. Finally... I tried doing the source installation but when I get to the configuration step, I get the following error: -bash: ./configure: No such file or directory The file is "mysql-5.1.47-osx10.6-x86_64.tar.gz" so I think it is the proper file for source installation and yes I have a 64 bit system. I don't know what to do anymore. Any ideas? Thanks, Hristo

• Force dual-mono audio (L+L or R+R) in Youtube video playback for one-channel audio movies

  - by jakub.g

  Occasionally, I find Youtube videos that have only one audio channel (only left or only right); example video (left channel only). This is quite annoying, especially with headphones on, as I hear sound in one ear, and no sound in the other. So, I want to be able to easily force dual mono (Left+Left or Right+Right) when I find that kind of video, and switch to normal stereo after I finish watching it. I have my headphones plugged well / I don't create audio/video - I want it for real-time playback only, In Windows audio config, setting balance 100% to Left / Right doesn't help (I have either still only left when moved to left, and no sound at all when moved to right), I've checked all the configurations in Control Panel > Sounds and Audio Devices > Audio > Sound Playback > Advanced like suggested in this post, in conjunction with moving balance left/right, and it doesn't seem to have any impact on actual sound I hear in headphones, No need to mix L with R, I just want L+L or R+R, I prefer software solutions to buying a stereo-to-mono adapter, Free solutions please, no $$$ ones, neither trials etc., In Control Panel > Realtek HD Sound Effect Manager I can turn on various mumbo-jumbo effects like: Concert Hall / Hangar / Bathroom / whatever environment (and in fact it makes the sound appear in two ears, but well, it's ridiculous to do this;), but there is no Dual Mono option. Finally, I know I can force L+L or R+R in VLC Player which supports Youtube (well, a little hack is needed, because Youtube internals change from time to time) but it is not very convenient to launch VLC just to play Youtube video - I want to keep it in the browser, I use Firefox generally (but well, if I don't find easier way, I will launch it in VLC).

• Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

  - by Piotr Jasiulewicz

  I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

• Chef: nested data bag data to template file returns "can't convert String into Integer"

• Wrong CSS mime type with Roundcube 0.5 beta and nginx

  - by Julien Vehent

  I'm running into a CSS problem. This is a setup based on Debian Squeeze (nginx/0.7.67, php5/cgi) on which I installed the latest Roundcube 0.5 beta. PHP is properly processed, login works fine but the CSS files are not loaded and Firefox is throwing the following errors: Error: The stylesheet https://webmail.example.net:10443/roundcube/skins/default/common.css?s=1290600165 was not loaded because its MIME type, "text/html", is not "text/css". Source File: https://webmail.example.net:10443/roundcube/?_task=login Line: 0 Error: The stylesheet https://webmail.example.net:10443/roundcube/skins/default/mail.css?s=1290156319 was not loaded because its MIME type, "text/html", is not "text/css". Source File: https://webmail.example.net:10443/roundcube/?_task=login Line: 0 As far as I understand, nginx doesn't see the .css extension (because ofthe ?s= argument) and thus set the mime type with the default value, being text/html. Should I fix this in nginx (and how ?) or is it roundcube's related ? Edit: It seems that it's nginx related. The content-type isn't set for any other type than text/html. I had to include manually the following declarations to force CSS and JS content-types. That's ugly, and I never had the problem before... any idea ? location ~ \.css { add_header Content-Type text/css; } location ~ \.js { add_header Content-Type application/x-javascript; }

• Grant access for users on a separate domain to SharePoint

  - by Geo Ego

  Hello. I just completed development of a SharePoint site on a virtual server and am currently in the process of granting users from a different domain to the site. The SharePoint domain is SHAREPOINT, and the domain with the users I want to give access to is COMPANY. I have provided them with a link to the site and added them as users via SharePoint, which is all I thought I would need to do. However, when they go to the link, the site shows them a SharePoint error page. In the security event log, I am showing the following: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:11:49 AM User: COMPANY\ThisUser Computer: SHAREPOINT Description: Object Open: Object Server: Security Account Manager Object Type: SAM_ALIAS Object Name: DOMAINS\Account\Aliases\00000404 Handle ID: - Operation ID: {0,1719489} Process ID: 416 Image File Name: C:\WINDOWS\system32\lsass.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: ThisUser Client Domain: PRINTRON Client Logon ID: (0x0,0x1A3BC2) Accesses: AddMember RemoveMember ListMembers ReadInformation Privileges: - Restricted Sid Count: 0 Access Mask: 0xF Then, four of these in a row: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:12:08 AM User: NT AUTHORITY\NETWORK SERVICE Computer: SHAREPOINT Description: Object Open: Object Server: SC Manager Object Type: SERVICE OBJECT Object Name: WinHttpAutoProxySvc Handle ID: - Operation ID: {0,1727132} Process ID: 404 Image File Name: C:\WINDOWS\system32\services.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: NETWORK SERVICE Client Domain: NT AUTHORITY Client Logon ID: (0x0,0x3E4) Accesses: Query status of service Start the service Query information from service Privileges: - Restricted Sid Count: 0 Access Mask: 0x94 Any ideas what permissions I need to grant to the user to get them access to SharePoint?

• switchless Infiniband between two servers on RHEL 6.3

  - by exfizik

  I have 2 servers running RHEL 6.3 which have 2 port Infiniband cards >lspci | grep -i infini 07:00.0 InfiniBand: QLogic Corp. IBA7322 QDR InfiniBand HCA (rev 02) I'm interested in connecting them directly to each other bypassing an Infiniband switch (which I don't have). Quick googling showed that at least in some configurations it's possible. I installed all RedHat Infiniband packages with yum groupinstall "Infiniband Support". However, ibv_devinfo shows that both ports in each card are down, which indicates that cables are not connected. But the cable is connected, although the LEDs are off on the cards (not a good sign). Another source of confusion for me is that according to this, RedHat doesn't come with OFED packages and I'm slightly hesitant to install them from source due to the lack of RedHat support for them... So where am I going with this? The questions I have are: is it possible to have a switchless/direct Infiniband connection between two servers the way I described above? If it's possible, do I have to use the OFED packages or can I configure everything with just the packages coming with RHEL. Why are the LEDs off on my servers even though the cable is connected? Any additional input/advice/pointers would be appreciated. P.S. I followed this guide for installation instructions. The Infiniband cards are clearly recognized by my OS and the rdma service is running. Update: I have opensm installed. When I run it it says: OpenSM 3.3.13 Command Line Arguments: Log File: /var/log/opensm.log ------------------------------------------------- OpenSM 3.3.13 Entering DISCOVERING state Using default GUID 0x1175000076e4c8 SM port is down and stays at that point.

• missing network usage through iptables

  - by Purres

  I inserted a rule to iptables to track the input usage to a certain ip address. The vps server's IP is 192.168.1.5 and the guest os's IP is 192.168.1.115. I ran 'yum update' inside the guest OS to get some network traffic. Then I ran iptables -vnL from the hypervisor. However it only showed network usage to the host, but not to the guest. Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target source destination 0 0 0.0.0.0/0 0.0.0.0/0 destination IP range 192.168.1.115-192.168.1.115 1853 114K 0.0.0.0/0 0.0.0.0/0 destination IP range 192.168.1.5-192.168.1.5 I ran tcpdump and the log showed that there're data packets to the guest os. 16:17:43.932514 IP mirrordenver.fdcservers.net.http > 192.168.1.115.34471: Flags [.], seq 17694667:17696115, ack 1345, win 113, options [nop,nop,TS val 1060308643 ecr 1958781], length 1448 16:17:43.932559 IP 192.168.1.115.34471 > mirrordenver.fdcservers.net.http: Flags [.], ack 17696115, win 15287, options [nop,nop,TS val 1958869 ecr 1060308643], length 0 Why the guest OS network usage couldn't be tracked? iptables -L will return the INPUT chain as following: Chain INPUT (policy ACCEPT) target prot opt source destination all -- anywhere anywhere destination IP range 192.168.1.115-192.168.1.115 all -- anywhere anywhere destination IP range 192.168.1.5-192.168.1.5 all -- anywhere anywhere

• Cannot open files in Visual Studio but in Delphi and Notepad

  - by Andrew J. Brehm

  About an hour ago Visual Studio 2008 decided that it cannot find files any more. This is on 64 bit Windows Vista. When I right-click on a text file (source code or otherwise) and select "open with" and "Visual Studio 2008", I get the following error (example): Windows cannot find 'C:\Users\ajbrehm\Documents\Visual Studio 2008\Projects\Hello Prism\Hello Prism\Main.pas'. Make sure you typed the name correctly, and then try again. When I right-click the same file and select "open with" and "Delphi 2010" or "Notepad" (both other options available for text files on my system), the file opens correctly. Oddly enough when the file is part of a Visual Studio project and I open the project itself with Visual Studio (this works), I can open the file from within Visual Studio. Any ideas what might be going on? This started about an hour after I made a complete backup of my Vista VM and after I installed IIS 7, SQL Express, and Sourcegear Vault. The first files I noticed couldn't be opened in Visual Studio any more where Pascal source files in checked-outed folders from Vault. And Vault also seems to be unable to see one of the sources files and claims they don't exist. I found out about Visual Studio not opening ANY files any more when I tried to recreate the file Vault refused to see. Update: I just checked. Another user, "administrator", can still open text files with Visual Studio 2008. Both users have administrator rights. Update: I just restored the hours-old backup. Same problem. Apparently whatever triggered this happened before the install of IIS 7 and SQL Express. Never noticed it before.

• iPhone Remote with iTunes Library via VPN

  - by sudo work

  Alright, so I'm currently behind a network router (not under my control). The router performs NAT and somehow prevents a computer from scanning other nodes. At least, you're unable, in this instance, to locate an iTunes library. You can, however, communicate with a node's open ports if the local IP address is known, as well as the port. I haven't actually tried port scanning a specific IP using nmap or another tool yet. So I've tried one solution to remove the contribution of the router entirely (to verify that it works without the influence of the routers). I set up an access point using my iPhone and tethered my computer (with the library) to it. From here, I was able to pair my library and the iPhone Remote application. Control of the library was normal as well. This solution is not ideal, however, because I am actively using bandwidth with my computer and cannot afford to be tethered to my 3G connection. A viable solution for me is to use a common VPN connection, which I have set up on a Ubuntu (Intrepid) server that is remote. Both my computer and iPhone are able to access the VPN via PPTP. The server is setup with PPTPD as the VPN-server; I'm using IPTables to perform IP masquerading and forwarding traffic. I however, still cannot connect the library to the phone. I can however, see both devices on the VPN subnet (192.168.0.0/24). SSH'ing and such works fine. What settings on the VPN server must I change to get this to work? Also, how can I assign static IP addresses to various PPTP clients based on MAC addresses?

• r1soft agent is failing with the error: "write error while sending code: Broken pipe"

Note: CDP 2.0 is installed in the backup server.

• SIP and NAT routers?

  - by OverTheRainbow

  Hello SIP was not built with NAT routers in mind, and I'd like to get to the bottom of this issue to check what needs to be done on all devices so it works with NAT routers, and understand in what context it just can't be used and I should check more NAT-friendly alternatives like IAX. A picture being worth a thousand words, here's the layout I need to use: http://img62.imageshack.us/img62/4077/sipandnatrouters.jpg The PBX server is located in the private LAN behind a NAT router connected to the Internet (I know it'd be easier if it were located in the public network, but this router doesn't support DMZ's so the server has to be in the private network) A couple of (soft|hard)phones are located on the same LAN and connected to the PBX server, along with a PSTN gateway (Linksys 3102 or a Digium PCI card) Remote users using (soft|hard)phones are located somewhere on the Net with dynamic IP's and are also located behind NAT routers I may or may not have control over the local NAT router where the PBX server is located, but I have no control over the remote NAT routers, either because the users don't have the computer knowledge to map ports or because the routers are off-limit (eg. web cafés, hotel LAN's, etc.) Is it possible to configure the PBX server, the (soft|hard)phones, and the PSTN gateway so that the all conversations work fine, no matter the endpoints (POTS caller/local phone, POTS caller/remote phone, local phones, remote phone/local phone)? In which cases may I expect problems, and are there solutions? FWIW, I'm leaning toward using Freeswitch, but I could end up using Asterisk if there are technical advantages to it in this context. Thank you for any info.
