• Unreceived SNMP traps

  - by Stephen Murby

  I have 2 CISCO IE3000 and 2 IE3010 switches. They are each configured to send traps to the one host which hosts my NMS [ManageEngine]. The only traps I have enabled on the switches are authentication and linkStatus messages (Up/Down), currently I have my NMS polling with the right community and receiving as ManageEngine checks when adding a managed device, but no linkStatus traps are received. I know they are coming because I have capture them with wireshark, but they are not received by my NMS, any ideas?

• Prevent users from creating / copying / moving anything except .exe

  - by webnoob

  We have a program that compiles executables into a folder into c:\bin. Ideally I would like to share this folder so users can access the exe's within but stop them creating any other files in there. The reason for this is to stop users grabbing source code and putting it in a shared drive then taking it. We have a Domain Controller setup and all the users belong to a specific security group. Is there any way to achieve this? EDIT: TO clarify, I need to stop users from creating or moving files INTO the C:\bin folder which are not executables.

• Is there a way to explore my WHS files via Xbox 360's Media Center app?

  - by bangoker

  I know its a "Console" question but its really more of a Media Center Extender question! I can access the data through the Video/Pictures options, but not through the Media Center App. Also I can only see the videos that are directly on the Videos folder on my WHS, but not any of the subfolders. Same thing in my Laptop, if I connect to my WHS through Media Player it will only show the videos on Videos but not any other sub-folder, but if I open Media Center I can then connect to server and see all the folders.

• IP routing Solaris 9 access the internet from local network

  I am trying to configure the NICS on the Solaris Sparc server. My problem lies in getting out to the "Internet" from the local network.

• Flow of packet in network

  - by user58859

  I can't visualize in my mind the network traffic flow. eg. If there are 15 pc's in a LAN. When packet goes from router to local LAN, do it passes all the computers? Means did it goes to ehernet card of every computer and those computers accept the packet based on their physical address. To which pc the packet will go first? To the nearest to the router? What happen if that first pc captures that packet(though it is not for it)? What happens when a pc broadcast a message? Do it have to generate 14 packets for all the pc's or only one packet reach to all pc's? If it is one packet and captured by first pc, how other pc's can get that? I can't imagine how this traffic is exactly flows? May be my analogy is completely wrong. Can anybody explain me this? Thanks in advance.

• Viewing file: protocol requests made from a swf

  - by Erik Vold

  I've got a swf file in a index.html file, the swf is basically loading images, but it requests a xml file which details where the image/asset files are located. Now the index file (which is just html, js, and css) works (ie: the swf file is working) when used on this url: http://localhost:8500/core/index.html which I'm able to do with Coldfusion 8 single server development environment. But when I access the file directly with this url: file:///C:/ColdFusion8/wwwroot/core/index.html the swf file does not work. So I'm guessing that the swf is having trouble locating the files that it needs. The problem is I have no idea what file urls it is try to access atm, and both Firebug and Fiddler are not able to inform me what requests are made on the file: protocol. So is there another tool that I can use?

• DLINK Dir-655 Sharing and connecting wirelessly

  - by CYREX

  I have a D-LINK DIR-655 and i wish to do the following: My PC is connected to the internet via eth0 (Wired) and it has a wireless card. I wish to connect to the DIR-655 Router and share my connection via the router but wirelessly. I do not want to connect via a cabled wired to the router. I want to connect to the router via wifi. After that i want to make the Router share the wireless connection am giving it to other PCs wirelessly. So the sharing and connecting in all PCs will be done via WiFi.

• Use-cases for assigning multiple IP addresses to 1 NIC

  - by Harry

  What would be some of major use-cases in which you would want to assign multiple IP addresses to your NIC? Knowing of any standard/well-known 'gotchas' associated with each use-case would also be helpful. For example, I heard someone saying that a user with access to such a machine will automatically get access to both networks, which could be a security issue. You can assume a Linux-based environment.

• change default userid for connecting to local AFP share?

  - by Stew

  I've got Netatalk & Avahi running on a local Ubuntu server--I use two different userids, "afp" for Time Machine and "stew" to access my media files etc. In order to mount a shared directory on my server, I have to click "Connect As..." and enter my userid/password every time, because it always tries to log in using Time Machine's userid. I'm not sure if this is because that userid is set as default, or just because it's the last userid that logged in to that server--either way: Is there a way to change the default userid for connecting to a given server? Mega extra credit: I'd love to have this automated, such that my userid, "stew", is always logged in (and heck, it'd be great to have the directories always mounted, too!) whenever the server is available. Thanks!

• capture nimbuzz traffic

  - by lurscher

  I need to capture all the traffic, specially during login, between nimbuzz pc client and nimbuzz server. The reason is that i need to debug outgoing packets at login that mark the user visibility status in order to reproduce them in a in-house XMPP client application I've tried doing this with wireshark, but i seem to be pretty helpless with this tool. Also, the packets i've been able to see are all before the SASL negotiation happens, after that, i cannot see the xml packets being exchanged any help for how to achieve this task is greatly appreciated (preferably on Windows, since there is no nimbuzz client for linux, in any case i can install one in a VM and monitor the traffic between the VM instance in the linux host)

• How to Mount remote disc as local in Windows 7 and Windows 2003?

  - by Robert

  Is it possible to mount remote file system (on Windows 2003 server) as local disk in Windows 7? I have Windows 2003 server with software RAID and some shares. On another computer with Windows 7 I have software which can access only data form local or USB disks. This solution doesn't work because program doesn't see files in folder: Mount Remote CIFS/SMB Share as a Folder not a Drive Letter Everything is the same LAN.

• Files turned into folders on external hard drive

  - by Kashif

  I have a networked hard drive where I like to store audio/video/software and all sorts of other files for my house. While the software files are all intact and working, many of my video and audio files have been turned into folders! Can anyone explain why this is happening, how I can prevent it, and if it is possible to revert these "folders" back into files. Thanks much! An example of what the folders are named: "Highschool Graduation.avi", "Birthday party.avi", "Somesong.mp3" The HDD is connected to a Linksys E4200 router (Firmware Version: 2.0.37). This is how the HDD is networked.

• How to play WAV file through Network Paging Interface

  - by BGM

  In our building we have a Viking Paging ZPI-4 Interface for our intercom. The interface receives data from our Asterisk Phone system via a Cisco SPA112 Port Adapter which has it's own IP address on the network and converts digital into analog. Asterisk plays the "5" tone and then allows the user's voice to commence over the connection. Now, what I want to do is to play a wav file over this Viking Paging device using the Cisco Port Adapter. I know how to get Asterisk to do it, but I want to do this without Asterisk. I want some kind of program that can talk to the Cisco Port Adapter and then transmit the wav file into the Viking Paging Device. What kind of program do I need to get or make? Now, I found this link if it helps anyone with ideas. I also found this information, but I'm not sure how to apply it. I also found this, but it involves an arduino. However, I already have the analog-to-digital convertor, and the Viking will handle sending sound over the paging speakers. I just need to know how to send the wav file to the Viking via the Port Adapter. So far, I know my wav file should be formatted as 8bit mono, and I need to send the "5" tone to open the Viking Pager's channel. [update] I am trying to figure out if I can use VLC player to stream to the ipaddress of the Port Adapter. So far I'm not having success with that, and don't even know if it will work. Windows Media Player has a streaming option too. I am thinking that since the Cisco Port Adapter thinks it is a sort of phone, that the only way this can be done is via SIP.

• Not getting IP from ISP on Multicast Network

  - by Johan Nielsen

  Im having an odd issue with my ISP (COMX.dk) I have a managed access gateway box (Telsay) with three 8P8C ports for use with Internet and Ip-Tv (respectively on different VLANS (so does my ISP tell me)) To utilize a port you will need to register your device's mac address through an online interface. You will then get your device paired with a static ip. I am using one port actively and I have registered another device (router). The router is configured to listen for an active dhcpd on the network. When my router get a lease I get a private ip 192.168.2.2 (not the one bound to my mac) which is odd! I unconnected my router from the gateway and connected my laptop directly. Same thing happened - I was given a private address. I did a port scan on the gateway and found port 80 to be open and browsed to the ip. I was then presented with a management interface of a Belkin wireless router (HMMM!!!!) <--by the way, not my gear At this point I called the ISP to let them know of my issue/findings - Only to be replied "Well, we cant see any rogue dhcp servers" (thinking to myself, well I can) I then decided that it could be fun to try the other port of my gateway, only to experience the same. So I reconnected my router and used the remaining port to make an observer(wireshark promic etc.) I am able to see my router trying to discover a dhcp server but I can also see my ISP's IGMP and PIMv2 packages just repeating the same pattern. Hello...Hello...Hello :) So I called them again, only to get the same response, "we dont see any rogue dhcp's...we cant see the host you are talking to (mac address of the Belkin router)...you are definitively connected through wireless?!?(no im not, no such thing as a wireless wire - i thought to myself)" My questions is, What is going on? (besides from what im reporting here) What am I seeing that the don't? What can I tell them in order for them to resolve mine/their issue?

• Media center consumes all available memory when attempting to play music off of a server

  - by RCIX

  I have Windows 7 Ultimate, and recently, when i try to play a song off of my Twonky Media Server/Windows Media Connect (based on an HP WHS with an Atom), it plays choppily. When i open Resource Monitor, it shows that after ordering the music to play, memory usage rapidly spikes to consume most, if not all, of the available memory on my system (excluding a couple hundred megabytes in standby). Why does it do this and is there anything i can do to stop it? Edit: it happens when I attempt to browse the server's music, not just when i play music. Edit 2: the "ehshell" process is what consumes the memory, appears to me something specific to media center. Moreover, the ehshell process doesn't die in this case. Edit 3: It only happens when browsing my Twonky library, and not my Windows Media Connect.

• Slowdown upon router/modem setup change

  - by Ollie Saunders

  I’ve been using a Belkin FSD7632-4 modem router to connect to my TalkTalk provided ADSL internet connection for some time and been pretty happy with it. Recently, however, the connection has been failing and I decided to get a ASUS RT-N16 instead, which is also a much more capable router generally. The ASUS RT-N16 doesn’t come with a modem built-in so I purchased as Zoom modem as well. I’ve set them both up and am using them to post this message. But I’m a bit miffed to find that I get a significantly and consistently slower downstream rate from the new configuration than with the old Belkin. Belkin modem router: downstream: 3.45 mbps upstream: 0.73 mbps ASUS router + Zoom modem: downstream: 2.71 mbps upstream: 0.66 mbps Any ideas why this is? The really weird thing about this is that the Zoom supports ADSL2 and ADSL2+ but I don’t think the old Belkin does. At first I thought it might be due to the Zoom modem being limited to PPPoE instead of PPPoA, which my ISP supports, but then I tried using PPPoE with the Belkin and that still gave a high speed. I’m using VC-Mux encapsulation with both. VPI of 0 and VCI of 38. I pulled this data off the Zoom: Mode: ADSL2 Line Coding: Trellis On Status: No Defect Link Power State: L0 Downstream Upstream SNR Margin (dB): 12.3 11.8 Attenuation (dB): 43.0 24.9 Output Power (dBm): 12.9 0.0 Attainable Rate (Kbps): 3936 844 Rate (Kbps): 3194 840 MSGc (number of bytes in overhead channel message): 59 10 B (number of bytes in Mux Data Frame): 99 14 M (number of Mux Data Frames in FEC Data Frame): 2 16 T (Mux Data Frames over sync bytes): 1 8 R (number of check bytes in FEC Data Frame): 8 8 S (ratio of FEC over PMD Data Frame length): 1.9833 9.0594 L (number of bits in PMD Data Frame): 839 219 D (interleaver depth): 32 2 Delay (msec): 15 4 Super Frames: 15808 14078 Super Frame Errors: 0 4294967232 RS Words: 513778 111753 RS Correctable Errors: 126 4294967238 RS Uncorrectable Errors: 0 N/A HEC Errors: 0 4294967279 OCD Errors: 0 0 LCD Errors: 0 0 Total Cells: 1920175 237597 Data Cells: 205993 392 Bit Errors: 0 0 Total ES: 0 0 Total SES: 0 0 Total UAS: 34 0

• Methodologies for performance-testing a WAN link

  - by Chopper3

  We have a pair of new diversely-routed 1Gbps Ethernet links between locations about 200 miles apart. The 'client' is a new reasonably-powerful machine (HP DL380 G6, dual E56xx Xeons, 48GB DDR3, R1 pair of 300GB 10krpm SAS disks, W2K8R2-x64) and the 'server' is a decent enough machine too (HP BL460c G6, dual E55xx Xeons, 72GB, R1 pair of 146GB 10krpm SAS disks, dual-port Emulex 4Gbps FC HBA linked to dual Cisco MDS9509s then onto dedicated HP EVA 8400 with 128 x 450GB 15krpm FC disks, RHEL 5.3-x64). Using SFTP from the client we're only seeing about 40Kbps of throughput using large (2GB) files. We've performed server to 'other local server' tests and see around 500Mbps through the local switches (Cat 6509s), we're going to do the same on the client side but that's a day or so away. What other testing methods would you use to prove to the link providers that the problem is theirs?

• OpenBSD has open ports in default installation

  - by celil

  I have been considering replacing Ubuntu with OpenBSD to improve the security on my local server. I need to have ssh access to it, and I also need it to serve static web content - so the only ports I need open are 22 and 80. However, when I scan my server for open ports after installing OpenBSD 4.8, and enabling ssh and http at /etc/rc.conf httpd_flags="" sshd_flags="" I discovered that it had several other open ports: Port Scan has started… Port Scanning host: 192.168.56.102 Open TCP Port: 13 daytime Open TCP Port: 22 ssh Open TCP Port: 37 time Open TCP Port: 80 http Open TCP Port: 113 ident ssh (22) and http (80) should be open as I enabled httpd and sshd, but why are the other ports open, and should I worry about them creating additional security vulnerabilities? Should they be open in a default installation?

• Having problems VPN'ing into our Windows server network.

  - by Pure.Krome

  Hi folks, When two people (on their notebooks) try to VPN to our office, only the first user gets a connection. the second user always times out. Is it possible for VPN to allow two or more people, using / sharing the same EXTERNAL PUBLIC IP to connect/authenticate? Now for some specifics (cause those two statements are very broad). I'm not in the IT Dept. I'm a developer. Our IT Dept don't really care (sigh) so it's up to me to fix this crap. Our office is all Microsoft shop stuff - servers and clients. We also have a firewall (watchguard brand?) and some other crazy setups (yes i know, it's very vague :( ). So i'm wondering - is it possible for multiple users, from the same public IP, to connect via VPN to a windows server? i'm under the impression - yes. But it is possible that this only happens when the clients (who are all behind the single, public IP .. otherwise they will have their OWN ip's) need to have UPnP running or something? this is killing me and i need to start asking the right questions cause these guys don't know what they are doing and i can't work without this happening. I know this is a vauge question with so many 'if-what's-etc' but maybe some questions/suggestions from you guys might start to lead to solving this problem. EDIT: Network Connection: WAN Miniport (PPTP)

• Streaming music throughout the house on a budget?

  - by greggannicott

  I was wondering whether anyone knew of a way to stream music throughout a house on a budget? I want to avoid spending any money on this (eg. I don't want to buy a d-link style device). It would be ideal if I could use my existing hardware and some open source software. I have three old(ish) PCs knocking around. I'm happy to stick either Windows or Linux on them. They can all be hooked up to speakers. The ideal solution would result in: the same audio being heard from every device (eg. when you hear a beat on one device, you'd hear it at the exact same time on another (so you don't get any echo)) I'd be able to control the source application (eg. the songs lined up) with my iPhone. I realise I'm being cheeky with those two wishes - but you never know your luck. Am I asking for too much, or is there a piece of software/protocol out there with this purpose in mind? I've been searching for sometime now, but haven't had any joy. Thanks in advance.

• Hyperic HQ metrics not working

  - by Robin Weston

  I am having a problem with Hyperic HQ. Several metrics, some in IIS 6.x (Request Execution Time, Request Wait Time) and some in .NET 2.0 (Bytes in all Heaps, Exceptions Thrown per Minute), always show 0. If I view perfmon on the server itself I can see that the counters have values greater than zero. There are some metrics that work fine, such as Total Get Requests per Minute and the other IIS defaults. I have looked in the server logs but nothing obvious shows up. Please advise. Am happy to find more information if required.

• Process PHP files from a network share in a vmware virtual machine

  - by nhinkle

  As a testing environment, I have set up a vmware virtual machine running Windows Server 2008 R2. I have Apache and PHP installed (as part of the xampp package). I am doing the development outside of the VM, and so want Apache to serve PHP files from a VM shared folder (which appears as a network share in the VM). I have done this by creating an NTFS symbolic link in Apache's htdocs directory. I can access this directory from the browser, and plain-text files are readable. However, PHP fails to process files, instead returning the following error: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'C:/xampplite/htdocs/path/to/file.php' (include_path='.;C:\xampplite\php\PEAR') in Unknown on line 0 It appears to be a permissions issue — PHP doesn't seem to be allowed to read the file to process it. However, Apache has no problem opening files in the directory. I cannot figure out how to give PHP the necessary permissions to process the file. Does anybody know of a way to make this work, or else another solution for getting the files into the VM automatically while I develop on the host machine?

• Ubuntu network card problem.

  - by Steve Greene

  Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, it works fine under Windows Vista. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System.
