• Database for heat tolerances of various cables?

  - by I. F.

  Is there any kind of unified database of heat tolerances for networking cables? I've been setting up a number of home/small office networks lately and as a mostly-amateur I could really use some information on what is safe to run behind a radiator, next to a steam pipe, etc. The question I'm up against at the moment is: Can I run normal RJ11 phone line cable (from DSL modem to phone jack) behind a steam radiator without risking a fire? Unlike cat5, I could not find published standards for these, so I'm turning to experts with more experience. This is a cut-rate show. Do I go out and buy more cabling, and if so which, or use the spare that I have?

• Hosts file in Apache keep changing for OS Linux Redhat [on hold]

  - by jack f

  I have installed Apache server. Two clients ex client_1 and client_2. The operation that we are performing on client_1 reflecting to client_2. We have etc/hosts file in our software install location which is keep on changing for client_2 with client_1 IP address. If I correct the entries in hosts file to client_2 also in the next few minuets it is changing automatically to the client_1(if we start the client_1 service). Please explain the use of hosts file and where and when it will change by Apache service.

• How to know what dll or services taskhost.exe is hosting?

  - by tigrou

  I have recently discover a new process in the task manager : taskhost.exe (maybe it was there before but i did not notice it) As the name implies, it seems to be used for running dll in background (like rundll32.exe). Is there a way to know which dll / services this process is hosting ? i would like to know for which purpose it is used and if there is some malware or not. I know it is possible to see which services svchost.exe process is hosting using process explorer utility. I have checked taskhost.exe threads and their stacks using process explorer, here is what i get : So it seems it is used for sound (winmm + playsndsrv). But there is also other things for which very few information is provided (ex : thread 1456, taskhost.exe as start address and nothing relevant can be found in stack (same for 1464, 2272 and so). So maybe it is not the right way to do.

• Enter response once prompt returns?

  - by mjb

  It's neither a secure idea nor one I'd recommend elsewhere, but I have a situation when occasionally it takes a while for my Ansible ad-hoc command to respond. I'd love to pipe or args or whatever is needed to push the required text into the prompt so I can walk away and know it will finish. Ex: $ ansible all -m shell -a "reboot" --ask-pass Password: blah blah blah it worked I'd love to send an argument or << or something to get the password in. Is that possible?

• VM's, virtual networks and my home network.

  - by Jason Taylor

  I want to create a small lab of VM's to test out networking with. I have two PC's running VMWare and I need the VM's on these two PC's to be connected to their own LAN. I am planning on bridging the VM's into my home network. My home network and PC's are in the 192.168.0.0 range, but I want my VM's to be in 10.1.0.0. If I do it this way (Bridging the VM's on both hosts into the network) will the VM's be able to communicate? Will my home router freak out seeing two different subnets? Is there another, easier way to connect the virtual lan's on two vmware workstations together?

• Is Exchange protected from/allow back dated emails?

  - by David

  Does Exchange Server adequately protect against backdating items in a mailbox folder? I want to determine from an auditing perspective what level of risk exists/what trust can be put into Exchange database records. Is there a (mis)feature that allows end point users to modify the sent/recieved date fields on their own messages? Is there a reasonable way short of hand editing the files for an Exchange Server admin to make such a change? And most importantly: Is there any kind of "sequence number" that we could use to audit Exchange records for evidence of date manipulation (ex. msg100 = Dec 15, msg101 = Dec 10, msg102 = Dec 16)

• Connect macbook to my LAN through a VPN - best solution? [closed]

  - by LewisMc

  So I have a LAN connected via a ADSL/PPPoA, this is using a bog-standard DLink router supplied by my ISP (talktalk UK). I have a NAS within the LAN that is running FreeNAS and I want to be able to connect to it when I'm out and about. It's running an atom so it's quite low on juice consumption but I don't want to have it on all day and night so I've been waking it via a magic packet and booting it down from the web admin when I need it. So I want to connect to the LAN, I presume via a VPN, to be able to send a magic packet. But what is the best method to accomplish this, or is there an easier way? I've been looking at the cisco 857 integrated router and the Netgear prosafe 318(behind modem) but not sure If I'm on the right track with what I want to achieve as I've not much experience or knowledge with VPN's or networking (software engineering student). I have tried port forwarding but to no avail, either with magic packets or even connecting outside the LAN via DYNDNS. Thanks,

• Encrypt backups with GPG to multiple tapes

  - by Dan

  Currently, I use tar to write my backups (ntbackup files) to a tape drive fed by an autoloader. Ex: tar -F /root/advancetape -cvf /dev/st0 *.bkf (/root/advancetape just has the logic to advance to the next tape if there is one available or notify to swap the tapes out) I was recently handed the requirement to encrypt our tape backups. I can easily encrypt the data with no problems using GPG. The problem I'm having is how do I write this to multiple tapes with the same logic that tar uses to advance the tapes once the current one is filled? I cannot write the encrypted file to disk first (2+TB). As far as I can tell, tar will not accept binary input from stdin (it's looking for file names). Any ideas? :(

• How can I determine Breaking point of my Web application using JMeter?

  - by Gopu Alakrishna

  How can I determine Breaking point of my Web application using JMeter? I have executed the JMeter Testplan with different concurrent users load. EX. 300 users(0% error), 400 users(7% error in a sample, 5% error in another sample), 500 users(more than 10% error in 4 out of 6 samples). At What value of % Error, I can say system reached the Breaking point.I used concurrent users 300, 400, 500 in a PHP website. Should I consider any other parameter to determine breaking point. How many maximum concurrent users my application can support?

• How to manage SOAP requests to a pool of VM each listening on a HTTP port with a priority value in these requests?

  - by sputnick

  I have a front SOAP web-server under Linux. It will have to communicate with Windows Servers VM listening each on a HTTP port, for a HTTP POST request. The chosen VM should return a report of the task to the SOAP client. In the SOAP requests, there's a special variable : the priority of the request (kind of SLA), and my question is coming right now : I think of using a ha software (nginx, HAProxy, HeartBeat...) that can manage priority in this point of view. Is it relevant or do you think I need to implement a queue by myself with some specific developments? Ex: I have a SOAP requests with low priority in the pipe : the weight priority for these VM should be decreased if I have high priority SOAP requests at the same time. Any clue will be really appreciated.

• Domain account credentials fails to start scheduled tasks

  - by neoco

  I have 2 Windows 2000 servers in a domain 'DC', which run numerous windows scheduled tasks under the 'DC\Task-User' account. These tasks are and have been running successfully in the past couple of years without any account/password modifications. Yesterday, the tasks went to 'Could not start' status. Myself having an admin account, was able to run these tasks with my credentials. Today, I ran the tasks again under the DC\Task-User account and they seem to be running fine without any issues. This has happened in the past too. I'm not into networking so don't know much about the underlying problem. Has this something to do with a Domain controller account authentication? Any pointers will be great!

• HP Virtual Connect and VLAN Tagging

  - by JaapL

  We have a c7000 chasis with the ability to have 8 uplinks per ESX host. Only 6 are currenlty active. I have a Virtual Switch with multiple vlan port groups and all the VMs are working fine. Recently we've been asked to setup network load balancing for one of our VMs, so we had our Virtual Connect engineer activate the last two uplinks. We then created a new vSwitch and added the two new uplinks to this vSwitch. We then moved the VM to this new vSwitch, but we get no connectivity. What could be the issue? We also added the appropriate VLAN ID. The VConnect engineer says everything is configured correctly and networking TEAM says the appropriate trunking is setup, so we are at a loss...

• Generic Windows 98 USB Drive drivers?

  - by Electrons_Ahoy

  I've got an old Win98 machine that I'd like to pull some data off of. (Tens of gigs of data, actually.) The machine still runs fine, but due to the age, it doesn't have a cd burner, and the pre-NT networking won't connect to SMB shares without a fair amount of wrenching on the registry that I don't really want to do. What I really want to do is plug in an external USB hard drive and copy the files. But - Win98 didn't ship with generic USB drive drivers, and external drives don't ship with them these days. Can anyone point me at a reputable generic driver I can install?

I can get to it in cmd.exe on the client but how can I manage it in a GUI? explorer q: Throws error:

• Routing / binding 128 to one server

  - by Andrew

  I have a Ubuntu server with 128 ip's (static external ips 86.xx.xx.16), and I want to crawl pages thru different ip's. The gateway is xx.xxx.xxx.1, the main ip is xx.xxx.xxx.16, and the other 128 ip's are xx.xxx.xxx.129/255. I tried this configuration in /etc/network/interfaces but I doesn't work. It work if I remove the gateway for the aliases eth0:0 and eth0:1. I think this is routing problem. auto lo iface lo inet loopback auto eth0 auto eth0:0 auto eth0:1 iface eth0 inet static address xx.xxx.xxx.16 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:0 inet static address xx.xxx.xxx.129 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:1 inet static address xx.xxx.xxx.130 netmask 255.255.255.128 gateway xx.xxx.xxx.1 Also, please tell me how to "reset" every changes that I made in networking and routing. Thank you

• Saving Proxy Settings from different networks

  - by elcool

  I go to different clients and they all have their networks with different proxy settings. So I'm always having to change the proxy settings and saving the info in a notebook, and it becomes a pain after a while. So, any good way to save all those proxies and have them recognize the network I'm on and load up? Currently I maintain two: one in IE for clients, and none in Firefox for when I'm at home. And I think the last network I was on asked me to save the proxy and I think it went to system settings. But I don't know much about networking.

• Forbid links to open new tabs in Google Chrome

  - by Andrzej

  I'm looking for a solution to forbid links in Google Chrome to open new tabs (in most cases it is a target="_blank" issue). So, I want all links to open pages in currently active tab, not in new tab. I tried a wide range of addons (for ex. "Death to target=_blank") and greasemonkey scripts that are supposed to remove target=_blank attribute but none of them worked. It is extremally anoying when I want to switch between accounts in GMail or navigate from GMail to GDrive. I always get the new tab opened and I need to close last tab manually.

• My webcam just came on "out of the blue"

  - by AngryHacker

  I have a Microsoft LifeCam HD sitting atop my monitor. Today, completely out of the blue, its light came on -- I was simply browsing the web (in Chrome) when it happened. After about 5 minutes the webcam turned off. Naturally, I immediately suspected my ex-wife (when in doubt, I always suspect her), but she isn't computer savvy enough. I looked over the process list and didn't see anything suspicious. I am running a couple of open source projects and free apps (e.g., greenshot, powermenu, supertray), but I've had them for years. Autoruns reports nothing suspicious in the startup and neither does Windows Defender. Anyways, what could it be? What should I look at next?

• Windows 7: How to boot up in normal mode after improper shut down?

  - by Level1Coder

  I work in two different locations and whenever there is a power outage at one of the locations, Windows 7 detects that the system was improperly shutdown. Once the power is up, the PC powers on and Windows 7 enters REPAIR/SAFE mode where only someone physically in front of the PC can control it. (Networking is all disabled in this mode) Now before it enters REPAIR/SAFE mode, there is an option for a NORMAL boot. But the catch is that REPAIR/SAFE mode is selected by default with a 30 second timer. Once it automatically enters REPAIR/SAFE mode and if nobody is at the other location, I have no way to remote control it anymore. And then I have to drive over to the other location and reboot it and select boot into NORMAL mode. Where can I change this setting so that Windows 7 always boots into NORMAL mode no matter how many times it is improperly shut down?

• have 2 exchange servers to communicate together!

  - by Data-Base

  we have our exchange server 2007 (10.10.2.11) at work with domain "dddddd.com" and ironport and it work just fine! we need to test some thing at work with Exchange 2010 !! so we came up with this idea: we created a locked network and install firewall (10.10.2.88) the locked network has it's own DC and Exchange servers! we used the domain "dddddd.loc" any way it will be deleted! IPs DC 10.0.0.1 EX 10.0.0.11 now the Exchange server up and running in the firewall (10.10.2.88) we opened the ports and forwarded it to the Exchange2010 (10.0.0.11) in our main DC we defined the zone dddddd.loc to the firewall and the MX records as well but when we test we get error now how to make it so that the 2010 will send email directly to the 2007 (we will not use it to more that that)? and the 2007 will send the email to 2010 if the email has the domain dddddd.loc ?

• Computer connects to lan, but not the internet

  - by Jay

  I have a computer with Vista Home that can connect to the router, but it cannot get on the internet. I cannot ping google.com, the request times out. I've tried this on two separate networks and have no trouble with other computers connecting. I've renewed ipconfig, reset winsock, updated the wireless adapter, and the hosts file looks fine. I've tried disabling the firewall as well as a direct wired connection. I did a scan with Norton and it didn't find anything. Is there anything else I can try before resorting to a system restore? Update (Copied from Answer) Windows Update was able to find updates and install them (though, they could have already been downloaded previously). When I pinged Google by using their IP 66.102.9.103, it said it lost 25 percent of the packets. I successfully flushed the DNS but it didn't help. Also, I found safe mode with networking works fine.

• How to report abuse to website hosting company (GoDaddy) [closed]

  - by lgratian

  I'm not sure if this is the right place to ask such a question... Let's say that a website posted a picture of me, without my consent, and I want it to be removed (it's something private, could compromise my career if it's seen by someone that shouldn't). I sent them an email asking nicely that they should remove it, but they didn't respond and the picture is still there. Using 'Whois' I found that the website is hosted by GoDaddy. Is there a way (an email address, for ex.) to report to GoDaddy that one of the sites they're hosting does something illegal and to force them to remove the photo? I searched the site and found nothing about such a thing. Thnaks in advance!
