• Cisco T1 Routing Help

  - by Joseph

  Thanks to someone on this site I was able to get the Serial0/0 interface up. I now have: DCD=up DSR=up DTR=up RTS=up CTS=up My next challenge seems to be in the routing and/or PC ip setup. This are the pertinent details from L3: WAN Network: 6.59.186.60/30 Level3 Side: 6.59.186.61 Customer Side: 6.59.186.62 Cust. LAN IPs: 6.59.192.224/27 What would be the IOS commands to setup this route correctly? Am I correct that I would the choose an IP like 6.59.192.224, subnet 255.0.0.0, gateway 6.59.186.62? Thanks

• Need to re-build an application - how?

  - by Tom

  For our main system, we have a small monitor application that sits outside our network and periodically tries to log in to verify the system still works. We have a problem with the monitor though in that the communications component set (Asta 3 inside Delphi applications) doesn't always connect through. Overall, I'd say it's about 95% reliable, but that other 5% kills the monitor since it will try to log in and hang on the connection attempt (no timeout in the component). This really isn't an issue on the client side of the system since the clients don't disconnect and reconnect repeatedly on the same application instance, but I need a way to make sure the monitor stays up and continues working even when the component fails on a run. I have a few ideas as to which way to have the program run, the main idea being to put the communications inside a threaded data module so that if one thread crashes then another thread can test later and the program keep going. Does this sound like a valid way to go? Any other ideas how to ensure a reliable monitoring application with a less than 100% reliable component? Thanks. P.S. Not sure these tags are the most appropriate. Tried including "system-reliability" as one, but not high enough rep to create.

• apache returning "The connection was reset"

  - by usjes

  One of my dedicated servers had some network issue today and the data center has to replace some router. Since then the sites on that server returns "The connection was reset" error most of the time. I tried installing nginx and it opens better, but it still shows the error sometimes. Everything in the config seems normal, what could be causing this error? UPDATE: Just noticed that in whm apache status there are always only 1 requests currently being processed, 8 idle workers. I know for sure the server received thousands of requests per minute. What could be limiting this to such a low number?

• how to stream audio and video files, but use any media player on Windows (without using Windows file

  - by RamyenHead

  I want to access and play media files on machine S (Windows XP) from machine C (Windows XP). Using Windows File Sharing ("share this folder" stuff), if it works, I would share the folder containing media files on machine S, and I would be able to play media files, sitting in front of C, using any media player I want. Windows somehow ensures that the remote files behave like local files. But Windows file sharing won't work for me, is there any alternative? If two machines were both Linux, I would install an SSH server on S and use Nautilus from C to access and play media files. The reason why I can't use Windows file sharing is, my campus use two different subnets, I have S and C on different subnets and it seems that the firewall governing the whole network in campus doesn't allow file sharing between different subnets. I tried changing Windows Firewall settings on S to allow C in, it still wouldn't work, so it must be the other firewall.

• Webserver on a rotating server with NAT IP or changing IPs

  - by hpsoftware

  i would have to elaborate my questions so please have patience Explaining the logic. if you are familiar with logmein then it installs a client software on your computer then it kinda keeps tracks where you computer is as long as it's connected to internet. So you can always access your computer no matter where it is whatever it's IP is you just go to logmein.com and then you can just access it. Now what i am asking 1. Let's assume i have a website hosted on my laptop let's call it webserver. so then i move around i have a new IP sometime even on a hotel network is it possible to do something like what logmein does so i can keep moving around my Webserver to new IP but it has some local client or something which keeps updating my IP or something i am sure i would need a gateway server somewhere which is connected to my domain name via DNS so somebody accessing my website www.mywebsite.com goes to my main server then gets routed to my laptop which could be anywhere but my gateway server is able to communicate to my webserver I will keep updating the case description based on comments to make more sense. please have patience with me. Regards

• 12.04 disabling wireless via dbus does not work

  - by FlabbergastedPickle

  I am using a proprietary rt3652sta driver for my wireless card. It appears as a ra0 device on the 64-bit Ubuntu 12.04. According to the online documentation the following used to work definitely up to 10.04. dbus-send --system --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.DBus.Properties.Set string:org.freedesktop.NetworkManager string:WirelessEnabled variant:boolean:false This however has no effect on the aforesaid wireless card in 12.04. Also, rfkill does not work as it does not even list the wireless button (again, likely due to the wireless driver being proprietary): rfkill list It only lists the hci0 (bluetooth) one and one can block/unblock it accordingly but this has no effect on the wifi. ifup/down also does not work (AFAICT)... And this leaves me with disabling wireless through the network manager applet. However, trying to do so via dbus appears not to work and yet I would like to automate it via a script. Any ideas how I could find out the proper dbus structure for the call? Is this even possible in Ubuntu 12.04?

• Bootable and remote controllable imaging software?

  - by stefan.at.wpf

  I am looking for an imaging software, that one can boot from CD or usb stick (therefore without installing anything on the system!) and then control by some kind of remote desktop. So something like a combination of Acronis TrueImage's Bootable Media and Windows Remote Desktop. I don't even need to be able to store the backup on a network drive, as an external usb hdd is attached for these purposes. Background: A system that is normally controlled by SSH / command line and therefore has no keyboard/mouse connected that I could use to control Acronis TrueImage.

• iPhone always assigned wrong ip

  - by Ashley Ray

  for some reason most of the time my iPhone connects to the home network the ip address seems wrongly assigned as it 'loses connection' even even with strong reception. If I change the ip address to a static from 168.2.10 to 168.2.15 works fine until it appears to renew back to the prior. I am using a power-plug extender from the modem to router. Then have a laptop Printer playstation tv and another iPhone that always connect fine. The modem also has a crappy wireless which I haven't connected any devices to. I'm sure the forum will have a simple answer!

• How to close the logon process named NtLmSsp ?

  - by Aristos

  I have a windows 2003 server and time to time I am getting many login failures like this one. Logon Failure: Reason: Unknown user name or bad password User Name: administrator Domain: xx.xx.xx.xx Logon Type: 3 Logon Process: NtLmSsp Authentication Package: NTLM Workstation Name: XLHOST Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: 173.45.70.100 <- hacker Source Port: 4722 AND Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon account: user Source Workstation: XLHOST Error Code: 0xC0000064 The question is, how can I close this process of login ?, what I have left open and some one can try to login ? Some notes: I login to the server using tunneling, nothing is open except dns, email, and web ports, not even ftp, and all default ports are change and hidden. I also monitor port scan and capture any one that try to find the hidden ports. Probably it is something open... Thank you in advanced.

• Converge Voice and Data networks using Sonicwall

  - by skinneejoe

  We are looking to converge VOIP and Data traffic onto a single wire so that our client's VOIP phones pass data through to the users computer. We are specing out a new Sonicwall NSA appliance to handle routing functions and layer 2 switches to manage VLANS. Not a huge network, medium sized. What should I know about converging the networks onto a single wire? Obviously I'll want to prioritize voice traffic, is this handled solely in the Sonicwall with QoS configurations or do the layer 2 switches need to be configured differently? Any other pitfalls I should be aware of, or any good resources for learning more?

• Regression testing for firewall changes

  - by James C

  We have a number of firewalls in place around our organisation and in some cases packets can pass through four levels of firewall limiting the flow TCP traffic. A concept that I'm used to from software testing is regression testing, allowing you to run a test suite against a changed application to verify that the new changes haven't affected any old features. Does anyone have any experience or an offer any solutions to being able to perform the same type of thing with firewall changes and network testing? The problem becomes a lot more complicated because you'd ideally want to be originating (and testing receipt) of packets across many machines.

• Getting "Unable to find a medium containing a live file system" when installing 10.10

  - by Krastin Konstantinov

  I got this error while trying to install ubuntu 10.10 from a bootable USB stick on to Sony Vaio P series laptop. The disk boots into the language and installation type screen. After that it goes through the splash and pulls up this error: BusyBox v1.13.3 (Ubuntu 1:1.13.3-ubuntu11) built in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Unable to find a medium containing a live file system After getting this error the installation fails to start. I have used the same USB stick on some other laptops and the installation started as usual. Any help will be appreciated. My installation is i386 and my machine is Vaio P VGN-P610. I've tried every possible thing: Bios: [enable boot external] Boot order: [external] [hard drive] [network boot] Tried 2 different USB drives Tried 2 different external CD drives Tried 6 different downloads of both the desktop and netbook remix. All downloads were checked with MD5SUM. Ubuntu Desktop 9.10 installs properly in every version and from every source. Getting reaaaally frustrated.

• Computer froze up

  - by Arlen Beiler

  Why would my computer freeze up out of the blue? I have Apache Webserver w/php, and MySQL server installed. I am not sure exactly when it happened, but I was doing something on a wordpress site that I have installed, and it just waited and waited and waited. Then, all the folders on it that were open on my other computer closed, as though I had disconnected it. Then the skype account went offline. The computer was totally froze. I thought maybe it was someone on logmein, but disconnecting it from the network didn't do anything. I had to "crash" it (held in the power button till it shutdown). It started up normally then and the logs showed absolutely nothing wrong. And doing the same thing that I did when it froze didn't repeat the freeze. Any ideas, I never had this happen before.

• Setting a Static IP Running FreeBSD8 in VirtualBox hosted on Windows 7

  - by gvkv

  I'm using VirtualBox on Windows 7 (host) to run a FreeBSD (guest) based web server. I`ve assigned a static ip of 192.168.80. 1 to the (virtualized) NIC which is run in bridged mode. The problem is that when I ping an external server (such as google.com) I get a No route to host error: dimetro# ping google.com PING google.com (66.249.90.104): 56 data bytes ping: sendto: No route to host ... I can ping the BSD server from both another virtualized machine and my host machine and from the server, I can ping everything on the network. The router ip is 192.168.1.1/16. ADDENDUM: I have the following lines in /etc/rc.conf on the BSD VM to configure networking: defaultrouter="192.168.1.1" ifconfig_em0="inet 192.168.80.1 netmask 255.255.0.0"

• Samsung i780 networking problem

  - by Infinity

  Hello guys! Maybe this is not the right place to ask this, but I give a try for it. Please don't rate it down, just ignore it if you don't like. So I have a Samsung i780 mobile phone and I would like to use the internet through my wireless router. I have connected to it. I got an IP address. My laptop is also connected to the same wireless network and I can ping the mobile phone and I get answer. When I open the internet explorer and enter an address it says that it cannot connect to the internet. I have googled very much, but can't find the problem. What do you think, what is the solution?

• Group policy to disable notifications of particular errors?

  - by resolver101

  How do i disable the notifications of particular errors? A little background to my issue. During the installation of the Kaspersky, it disables all the windows firewall for all except the domain. I have remedied this by creating an offline policy in Kaspersky which enables the Kaspersky firewall when out of the office (ie not connected to the office network). The problem now is that users in the office now see a notification showing that the firewall is disabled even though it’s enabled in all scenarios. It’s just that work and home show as disabled when the clients are connected to the office LAN. I’ve looked into the notifications and you can disable the notification (not recommended) but I don’t want to do this incase other relevant messages are stopped from being displayed. http://blogs.technet.com/b/networking/archive/2010/12/16/disabling-firewall-alerts-in-the-action-center.aspx

• Geekswithblogs.net Influencer Programm

  - by Staff of Geeks

  Recently, @StaffOfGeeks announced to a select group of bloggers, the Geekswithblogs.net Influencer Program.  Here is a little detail about the program. Description (from Influencer Page): Geekswithblogs.net is a community of bloggers passionate about contributing information to the world of developers and IT professionals. Our bloggers are some of the best in the world and receive honors on a regular basis for outside companies (such as the Microsoft© MVP Program). The Geekswithblogs.net Influencer Program is our way as Staff of Geeks to show our appreciation for those bloggers who have the greatest influence on the site. Each influencer in the program is awarded by the amount of posts, views, and comments they receive on their posts in the previous quarter. Each quarter, we select the top 25 bloggers of influence and give them special access to products and services we have obtained through our network of partners. Here is how it works.  Each quarter we select the top 25 bloggers bases on the amount of posts that created in that quarter, and apply points to the views and comments those posts receive.  The selection is purely off of the numbers, we do not select any based on any other basis.  In fact in the first round, several of our key bloggers did not qualify in the top 25.  Though they are still loved dearly, we wanted a program that anyone could be a part of if they put in the hard work. This said, the first quarter ends at the end of March and we will have another round of influencers joining us.  Keep the posts rolling and maybe you will be selected as an influencer! Visit the influencers page to see who has the greatest influence on Geekswithblogs right now.   Technorati Tags: Geekswithblogs

• Do support sites like Stack Overflow upset the paid-support open source model?

  - by ajax81

  In order to stay relevant in the marketplace, I'm researching new business models for my software company. The open source model with paid support seems like a good fit for our product, but I have concerns about whether or not a paid support model is viable in an era where top-notch help is readily available for free on sites like those in the Stack Exchange network. Case in point -- I moved my employees to Ubuntu last year because I didn't want to pay for Win 7 licenses and new hardware (plus, the mono platform was highly attractive). My staff had no Linux experience, but were able to achieve relative competency in about 120 days with the help of AskUbuntu, Stack Overflow, and a few "For Dummies" books. We did employ an Ubuntu consultant for 7 days to provide training and support, but beyond that spent $0.00 on any kind of paid expertise. In regards to my due diligence, I ran a 3 month beta of the freemium-paid-support model with one of our smaller customers, and achieved mediocre results. I'd like to think its because our software is so stable and easy to use that the customer didn't need much paid support, but I suspect that they circumvented the terms of our SLA in the same manner that we did with the move to Ubuntu. Does anyone out there has any thoughts, advice, or experience relevant to the move I'm considering? What worked, what didn't, etc?

• TCP connection stuck in SYN_RECV state despite ACK received, Linux 2.6.18, embedded, ARM

  - by waynix

  My client cannot connect to my protocol port (TCP) after some network glitches, even though all other protocols (telnet/HTTP/FTP) work fine. netstat shows that my server is listening and tcpdump on the server shows all 3 packets are exchanged: 18:29:16.578964 IP 10.9.59.10.3355 10.9.43.131.5084: S 2602965897:2602965897(0) win 65535 <mss 1460,nop,nop,sackOK> 18:29:16.579107 IP 10.9.43.131.5084 10.9.59.10.3355: S 3464857909:3464857909(0) ack 2602965898 win 5840 <mss 1460,nop,nop,sackOK> 18:29:16.579284 IP 10.9.59.10.3355 10.9.43.131.5084: . ack 1 win 65535 But somehow netstat -t shows the connection still in SYN_RECV, as if the ack is not seen by the TCP state machine. I have to restart my server to get it to work. syncookie is not enabled, and I know from client code behavior and tcpdump that there is no SYN flooding. Help much appreciated.

• Cross-Forest Trust

  - by cdalley

  I am looking at testing a cross-domain trust we can have two domain controllers (with different forests and domain names) setup so we can move everyone onto the new domain. We do NOT run exchange on site and we do not have any links to O365 to AD currently. Onto the problem: I have setup two DCs in a Virtual Machine: They are on the same network 192.168.0.* The Windows 2003 server: Name: OLDSRVR "Clone" of our current Domain Controller IP: 192.168.0.1 Domain: internal.test.com The Windows 2012 server: Name: ADCTEST01 Brand new domain setup from scratch separate to internal.test.com Domain: internal.test2.com IP: 192.168.0.2 OLDSRVR can only see ADCTEST if it has dynamic IP set. If I set a static IP it cannot see it. If I try using the dynamic IP and try to join it gets to the end then complains "??The trust relationship between this workstation and the primary domain failed" Any ideas?

• Report from OpenWorld Shanghai

  - by jmorourke

  Oracle OpenWorld Shanghai 2013 was held July 22nd – 25th at the International Expo Center in Shanghai, China. The conference drew over 19,000 attendees from 44 countries. In addition, 580 CxOs attended the Executive Edge program, and 430+ partners attended the Oracle Partner Network Exchange. The conference included a number of sessions on Big Data, Business Analytics, Business Intelligence and Enterprise Performance Management delivered by Oracle, our partners and customers.  I had the pleasure to attend the conference and delivered three sessions focused on Oracle’s Hyperion Enterprise Performance Management (EPM) applications. Each of my sessions was well-attended, and in a few cases was standing room only, so there is clearly a lot of interest in the China market in EPM. The EPM and BI demo pods in the DemoGrounds at the conference also received a lot of traffic. In addition to the conference sessions I delivered, I had several meetings with customers and partners in Shanghai.These sessions and meetings I attended made clear the interest that customers in China have in improving their planning, management reporting, financial reporting, and profitability management processes. In fact, with the China Ministry of Finance now standardizing on XBRL for annual reporting across multiple agencies in China, there is a great opportunity here for our disclosure management application. One interesting finding is that the China market may not be ready for cloud-based applications as many companies are state-owned and have security concerns, so on-premise applications are likely to see continued demand.  For more information about the Oracle OpenWorld China 2013 conference, please check the web  site:  http://www.oracle.com/events/apac/cn/en/openworld/index.htmlAnd don’t forget, Oracle OpenWorld San Francisco 2013 is just around the corner in September of 2013.
