  • SIP server ("gateway") for joining accounts

    - by Tomas Srna
    Hello, I have a phone supporting 2 accounts, but I need 4 accounts. Is it possible to install some sort of SIP server/gateway/proxy (on a linux server), that would register those 4 accounts and I would be able to connect to it as if it was 1 account? (With dialing rules, etc.) 3 of the accounts have incoming numbers. Thanks. Tomas.

  • Too many TIME_WAIT state connections!

    - by Hamza
    I've been reading about this everywhere all day, and from what I've gathered, TIME_WAIT is a relatively harmless state. It's supposed to be harmless even when there's too many. But if they're jumping to the numbers I've been seeing for the past 24 hours, something is really wrong! [root@1 ~]# netstat -nat | awk '{print $6}' | sort | uniq -c | sort -n 1 established) 1 Foreign 12 CLOSE_WAIT 15 LISTEN 64 LAST_ACK 201 FIN_WAIT2 334 CLOSING 605 ESTABLISHED 816 SYN_RECV 981 FIN_WAIT1 26830 TIME_WAIT That number fluctuates from 20,000 to 30,000+ (so far, the maximum I've seen it go is 32,000). What worries me is that they're all different IP addresses from all sorts of random locations. Now this is supposed to be (or was supposed to be) a DDoS attack. I know this for a fact, but I won't go into the boring details. It started out as a DDoS and it did impact my server's performance for a couple minutes. After that, everything was back to normal. My server load is normal. My internet traffic is normal. No server resource is being abused. My sites load fine. I also have IPTABLES disabled. There's an odd issue with that too. Every time I enable the firewall/iptables, my server starts experiencing packet loss. Lots of it. About 50%-60% packets are lost. It happens within an hour or within a few hours of enabling the firewall. As soon as I disable it, ping responses from all locations I test them from start clearing up and get stable again. Very strange. The TIME_WAIT state connections have been fluctuating at those numbers since yesterday. For 24 hours now, I've had that, and although it hasn't impacted performance in any way, it's disturbing enough. My current tcp_fin_timeout value is 30 seconds, from the default 60 seconds. However, that seems to not help, at all. Any ideas, suggestions? Anything at all would be appreciated, really!

  • IIS URL Rewrite Module Query String Parameters

    - by binarycoder
    Is it possible to use URL Rewrite to provide more complex query string functionality than the "Append query string" checkbox that it has? Specifically, is it possible to specify the keys for certain query string parameters and have it only append those name value pairs. For example, for the input: http://www.example.org/test?alpha=1&beta=2&gamma=3 and the list of query string parameter keys: beta gamma it should output: http://www.example.org/redirect?beta=2&gamma=3 (Note that the query string parameters in the input appear in arbitrary order.)

  • KeePass: use a key file or a regular password?

    - by RCIX
    I'm setting up a KeePass database and it offers the ability to use a key file, which it says is more secure because it can use a longer and more complex password but is easier to break because you only need the key file to open the database. I'll only be using the key file on 2 computers (one desktop and one laptop), wo which is the best option? Note that it's definitely more appealing to use the key file for me because i have a hard time remembering anything close to a random password.

  • What does transactions per seconds for a load balancer mean

    - by Anurag
    I was looking at the product matrix of webmux 592G(load balancer). It says maximum connections per sec = 2.8M Maximum number of transactions = 100,000 What does the above numbers mean. Does above means that load balancer can have 2.8M connections open but only 100K of them will be active per seconds. Also incase any one has used webmux 592G do you guys know in practice how many connections it can have open and what qps it can serve

  • How to interpret Rackspace server diagnostics?

    - by Ben
    We've been having some trouble lately with our site timing out during times of high traffic. We're working on a number of things to resolve it. During this process I came across our server diagnostics page on Rackspace, and it has the following line: The host server's load is: 0.08 0.08 0.03 1/204 2437 I couldn't find an explanation on their site or Google. Can anyone explain what these numbers mean? For I am a lowly programmer. Much appreciated, -Ben

  • Having trouble getting phpmyadmin installed in Ubuntu.

    - by George Edison
    Okay. I installed apache2 and php on my Ubuntu 10.04 machine. I copied the phpmyadmin files to /var/www/phpmyadmin so that the hierarchy looks like this: -var (755) -www (144) -phpmyadmin (644) -index.php... etc. (644) -index.html (644) The numbers in brackets are the permissions. What permissions should the phpmyadmin folder have? What am I doing wrong?

  • Is there such a thing as a game made using a spreadsheet?

    - by andygrunt
    Many computer games (especially the 'Tycoon' type games, Civilization etc) are essentially spreadsheets under the hood, displaying the results of their calculations with a veneer of pretty graphics. But, I've often wondered if anyone's actually created a game using a spreadsheet (using the standard formulas and functions available in a spready) but never actually come across one. So, can anyone point me to a spreadsheet game? - the more complex, the better.

  • Mac OS X Photo Tool: Cropping w/ particular aspect ratio

    - by Jason S
    I'm spoiled by FastStone on the PC. I'm looking for decent freeware/shareware for Mac OS X that will allow basic photo editing, particularly something that lets me pick a crop size or aspect ratio by entering in numbers rather than just a freehand crop (I need to make sure it's 8.5"x11" aspect ratio). Any suggestions?

  • Glassfish basic configuration forgotten

    - by Toto
    I installed glassfish v3 some time ago and it's been a while since I last used it, so I forgot the port on which the server is listening and the port on which the admin console is listening. Moreover, i forgot the admin password! I'm pretty sure I've change them because I've tried the default values and didn't work. Is there any configuration file where I can look for them (at least the port numbers)?

  • How do you pronounce IIS?

    - by Noffie
    I would always just spell it out saying "Eye Eye Ess," but my boss always calls it "Two Ess," like the II is roman numeral. I know it stands for Internet Information so it is not really numbers, but on the other hand it is a lot easier to say "Two Ess." Ps- This should probably be a community wiki.

  • How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7?

    - by Timo
    The question says it all, but more detail follows ;) I've got a new computer that runs Windows 7 64-bits (Home Edition) and I'd like to connect it to my wireless home network (Sitecom wireless gigabit router 300N wl-352 v1 002) with a Sitecom wireless USB micro adaptapter 300 wl-352 V2 001. After installing the router (i.e. connected to the modem and power) and ensuring that wireless is indeed enabled, I've installed the driver of the USB adapter on the new computer described above. After the installation (drivers and utility on CD) completes successfull I rebooted my computer and inserted the USB adapter. After discovering the right network and connecting to it using the network key, a connection is succesfully made. (Using the Sitecom 300N USB Wireless LAN utility). In the LAN utility I can see that the signal strength is approximately 50% and connection quality is approximately 80%. Judging from these numbers I assumed that all was fine and started to use the connection (reading news on nu.nl, a dutch news site), but noticed that the connection was lost several times in a very short time span, but each time the connections was resumed, resulting in the 50/80 percent numbers described above. However, the website was not loaded completely and often a timeout would be reported. When inspecting the drivers through Device Management (Windows' Apparaatbeheer in dutch) there were no errors/warnings; everything seemed to be in order. In an attempt to solve this, I downloaded the latest drivers for the USB adapter, but the problems remained. Finally I tried to connect the computer with a Siemens Gigaset USB Adapter 108. This process was a troublesome since I had to download a driver (from the site above) and tell Windows (7) to use the Windows Vista driver when installing the new hardware, since there is (was) no Windows 7 driver available. This resulted in a usable connection, although not very stable when reconfiguring the router. Which took the form of selecting a different wireless channel on the router, even using the Sitecom utility mentioned above to check if there were other networks communicating on that channel (and thus picking a channel that was not used by other networks). Again no result when changing back to the Sitecom USB adapter. Note that this means (I think) that I could use the internet connection with the Siemens adapter, meaning the problem was not in the router. So: How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7? PS Sorry, but should be able to post one link, while I had links in place for the USB adapter, router and the siemens adapter in place as well, but I'm not (yet) allowed to post these... (The site says I can post one link, but only when no links are present will it allow me to post the question...)

  • Setting Up a Virtual Sound Device To Stream Output via TCP/IP

    - by Martindale
    I'm interested in installing a custom driver / device that will open a socket (or listen) and stream audio via TCP/IP in both Windows and Linux. I would like to be able to specify this device as my "Output" for specific applications so that I can route my audio through a completely unique machine (for example, in complex Synergy setups where my headphones might be connected to one machine, but audio is being generated by another.) In Linux, I expect this to be very easy, but I anticipate having to install a custom driver in Windows.

  • Percentage of computers on Internet behind a NAT?

    - by Mr.M
    I'm in a process of developing a server application and I would like to know if there are some numbers (or experience from people) on how many computers are behind the NAT on the Internet? Since my application is supposed to be a small server, being forced to implement UPNP support and TCP hole-punching with an external server may sway my determination, especially if more than 80% of the Internet is behind NAT.

  • Are these acceptable temperatures for my laptop?

    - by WilliamKF
    I just installed SpeedFan 4.0 since my laptop's fan seems to be continually running at a high speed. It reports these numbers: GPU: 74C Temp1 (ACPI): 75C Temp2 (ACPI): 95C Core 0: 89C Core 1: 89C These seem awfully high to me, should I be concerned? This is an HP EliteBook 8730w with Intel(R) Core(TM)2 Extreme CPU X9100 @ 3.06GHz and nVidia Quadro FX 3700M.

  • How to select all text inside text area of code field on web pages

    - by Moorage
    In all the forums web pages the download links are given inside the [code] braces that looks like text area with white background. When the download links are in large numbers then there are scroll bars. I find it difficult to scroll up and then select and then drag down to select all links. Is there any way to select all , when I click on select all on right click then it usually selects the text from whole page not from that code segment

  • image filter that spits out pi

    - by patrickinmpls
    I've seen this before but I forgot what's its called. Does anyone know of software that takes a picture and spits out an image of the number pi, ie. 3.14... not the symbol? It basically kinda looks like ascii art but the numbers are different shades of gray so it is like a black and white photo. Thanks!
