• How to use DNS/Hostnames or Other ways to resolve to a specific IP:Port

  - by tomaszs

  This is a Canonical Question about DNS/Hostnames resolution to IPs/Ports Example 1 I'm running a web server on port 80 and another on port 87. I would like to use DNS so that www.example.com goes to port 87. How can I accomplish this using DNS only? Example 2 I'm running a service on my server on a non-standard port. How can I get clients to connect to this non-standard port automatically? Can I use DNS? Is there some application specific support where DNS could indicate the IP and Port? Example 3 Do some application protocols specifically support hostname awareness, and allow special actions to be taken based on this information? Are there other questions on Server Fault that cover some of these? Commandeering: This question was originally asking about running IIS and Apache on the same server, but the same concepts can be applied to any server software receiving connections from clients. The Answers below describe the technical problems and solutions of using DNS and application protocol support to assign a port number for a client to connect.

• port forwarding with socks over proxy

  - by Oz123

  I am trying to browse a wiki that runs on a server inside one domain from another domain. The wiki is accessible only on the LAN, but I need to browse it from another LAN to which I connect with an SSH tunnel ... Here is my setup and the steps I did so far: ~.ssh/confing on wikihost: Host gateway User kisteuser Port 443 Hostname gateway.companydomain.com ProxyCommand /home/myuser/bin/ssh-https-tunnel %h %p # ssh-https-tunnel: # http://ttcplinux.sourceforge.net/tools/stunnel Protocol 2 IdentityFile ~/.ssh/key_dsa LocalForward 11069 localhost:11069 Host server1 User kisteuser Hostname localhost Port 11069 LocalForward 8022 server1:22 LocalForward 17001 server1:7100 LocalForward 8080 www-proxy:3128 RemoteForward 11069 localhost:22 from wikihost myuser@wikihost: ssh -XC -t gateway.companydomain.com ssh -L11069:localhost:22 server1 on another terminal: ssh gateway.companydomain.com Now, on my companydomain I would like to start firefox and browse the wiki on wikihost. I did: [email protected] ~ $ ssh gateway Have a lot of fun... kisteuser@gateway ~ $ ssh -D 8383 localhost user@localhost's password: user@wikiserver:~> My .ssh/config on that side looks like that: host server1 localforward 11069 localhost:11069 host localhost user myuser port 11069 host wikiserver forwardagent yes user myuser port 11069 hostname localhost Now, I started firefox on the server called gateway, and edited the proxy settings to use SOCKSv5, specifying that the proxy should be gateway and use the port 8383... kisteuser@gateway ~ $ LANG=C firefox -P --no-remote And, now I get the following error popping in the Terminal of wikiserver: myuser@wikiserver:~> channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused Confused? Me too ... Please help me understand how to properly build the tunnels and browse the wiki over SOCKS protocol. update: I managed to browse the wiki on wikiserver with the following changes: host wikiserver forwardagent yes user myuser port 11069 hostname localhost localforward 8339 localhost:8443 Now when I ssh gateway I launch Firefox and go to localhost:8339 and I hit the start page of the wiki, which is served on Port 8443. Now I ask myself is SOCKS really needed? Can someone elaborate on that ?

• ¿Oficina sin papeles?

  - by [email protected]

  Recientemente hemos organizado un evento de Digitalización para mostrar algunos de los últimos productos de Oracle en éste área.Siempre tendemos a pensar que en España estamos retrasados en estas tecnologías y que el mercado no está preparado para eliminar el papel. En algunos casos es cierto, pero también nos hemos llevado sorpresas con clientes extremadamente avanzados en la gestión electrónica del papel.Para los clientes que no tienen una solución corporativa ya desplegada, nuestra oferta de Imaging les parece completa e integrada, porque les permite digitalizar el papel en el punto más cercano a su recepción y posteriormente realizar todo el trámite interno de forma digital.Este proceso es el que se muestra en la siguiente imágen: Sobre todo en el entorno financiero los clientes ya tienen grandes infraestructuras desplegadas (algunos con funcionalidades muy sofisticadas que han desarrollado a medida durante estos últimos años).En estos casos, su interés está centrado en 2 capacidades clave de nuestros productos: La digitalización distribuidaEl OCR inteligenteCuando ya disponemos de una infraestructura de digitalización centralizada, tenemos varios puntos de mejora con los que conseguir mayores ratios de ahorro en la gestión del papel. Uno de ellos es digitalizar en origen, de forma que ahorraremos en logística de desplazamiento y almacenamiento de papel (reducimos valijas) y en velocidad de arranque de los procesos (desde el momento de la recepción).El hecho de poder hacer esto sólo con un explorador de internet es muy novedoso para los clientes.El no instalar ninguna pieza de software de cliente parece que es un requisito que muchos clientes estaban demandando desde hace tiempo. De hecho, estamos realizando demos en vivo con un escáner del cliente (solo necesitamos el driver de windows para ese escáner). El resultado es sorprendente porque mostramos cómo: escaneamos con sólo un explorador de internet; el documento escaneado, con sus metadatos, se incorporan al gestor documental; y se dispara su workflow de aprobación.Hacer esto en segundos es algo que genera mucho interés en los clientes de cara a acelerar la gestión de muchos de sus trámites en papel.Por último, lo más novedoso de la oferta es el OCR inteligente. Hay quien ya tiene absolutamente operativas sus infraestructuras de digitalización con todas estas capacidades, y buscan un paso más allá con el reconocimiento inteligente de todos los metadatos posibles.El beneficio es rápido, claramente cuantificable y muy alto. El software de OCR inteligente se basa en lógica difusa y nos permite definir los umbrales de validación totalmente adecuados a nuestros factores de confianza. Es decir, configuramos el umbral para que cuando el software acepta un acierto tengamos la seguridad total de que dichos metadatos se han reconocido perfectamente. En caso contrario, el software lanza una validación manual.¿Qué pasa si conseguimos que para determinados documentos, el 40%, 50%, 60% o incluso el 70% u 80% de ellos fueran procesados 100% automáticamente?. El ahorro es inmenso, la reducción del tiempo de proceso también, y la integración con nuestras infraestructuras de digitalización es muy sencilla (basta con desviar unos cuantos documentos de un tipo concreto a Oracle Forms Recognition y evaluar el resultado).Os animo a que veáis estos productos y consigamos hacer realidad la reducción de papel.

• Accessing SQL Server using an IP Address and Port Number ... Help!

  - by Mike

  I need to access an SQL Server that is on a machine behind a firewall and you access this machine using an ip address like 95.95.95.33:6930 (not the real ip address) ... But, you get my point that by accessing 95.95.95.33 on port 6930, the firewall routes the requests to that particular machine ... My question is ... How do you construct a connection string to access the machine at address 95.95.95.33:6930 and then further access the SQL Server on port 1433 or maybe a different port like 8484 ??? Thanks Mike

• Stitch scanned images using CLI

  - by Adam Matan

  I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images. Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc. Hugin has a solution for this issue, but it isn't practical for batch jobs.

• Intel obligé de rappeler ses puces Sandy Bridge, à cause d'un problème de port SATA

  Intel obligé de rappeler ses puces Sandy Bridge à cause d'un problème de port SATA, il pourrait lui en coûter 1 milliard de dollars Mise à jour du 01.02.2011 par Katleen Parfois, une petite erreur peut chambouler de grandes choses. C'est ce qui est en train d'arriver à Intel, avec ces processeurs Sandy Bridge. La compagnie se voit en effet contrainte de les rappeler, ce qui risque de perturber le travail des constructeurs de PCs. En effet, les puces de la gamme Series 6 (qui sont incorporées dans tous les systèmes Sandy Bridge) ont un problème avec leur port SATA (Cougar Point) : il risque de "se dégrader avec le temps", ce qui pourrait avoir un impact sur les performances ou la fo...

• Find "secret" port number

  - by CJ Sculti

  this may be kind of an odd question. My friend has challenged me. So somehow, he change the "port" of his site to 31337. If you just go to domain.com, you get redirected to google, to access the real site you go to domain.com:31337. He is going to change it again and he is challenging me to find out which port it is. Is this possible without guessing? Hopefully someone can help! Thanks. Oh, and is this the right stack exchange site to post this on...

• Why does a port occasionally stop listening? This happens only on occasion

  - by Binh Nguyen

  I have a Windows Service written in C# that listens on port 8591. I also have a web application hosted in IIS on the same server that makes request to the service. On occasion the port will stop listening and throws the following error: "No connection could be made because the target machine actively refused it 127.0.0.1:8591". This happened 3 times in 2 months and just resolves itself. I can also fix it manually by restarting the service. I'm wondering if any one else has run into this problem and has possible suggestions to resolve. I'm a developer and have worked with our windows group extensively and they assure me there is no firewall or AV blocking the port on occasion. This is running on Windows Server 2008 R2. Very puzzled at what could be causing this to happen. Please let me know if you need more information.

• Port numbers appended to anchor tags

  - by glifchits

  I've built a static site. Locally, when I serve the content with python -m SimpleHTTPServer everything behaves normally, but when I copy the HTML onto the server and browse the site at the server's URL, some links will have a port number appended to the domain. For example: url.com:84/path where the correct path is url.com/path. The port number is usually different, always between 81-85. It is an Apache server. I'm not experienced with web server configuration, and I'm not the admin of the server. Let me know if there is more information that can help solve my problem. ~> cat /etc/*release* SuSE SLES-8 (i386) VERSION = 8.1 UnitedLinux 1.0 (i586) VERSION = 1.0 LSB_VERSION="1.2" DISTRIB_ID="UnitedLinux" DISTRIB_RELEASE="1.0" DISTRIB_DESCRIPTION="UnitedLinux 1.0 (i586)"

• Help me upgrade my pf.conf for OpenBSD 4.7

  - by polemon

  I'm planning on upgrading my OpenBSD to 4.7 (from 4.6) and as you may or may not know, they changed the syntax for pf.conf. This is the relevant portion from the upgrade guide: pf(4) NAT syntax change As described in more detail in this mailing list post, PF's separate nat/rdr/binat (translation) rules have been replaced with actions on regular match/filter rules. Simple rulesets may be converted like this: nat on $ext_if from 10/8 -> ($ext_if) rdr on $ext_if to ($ext_if) -> 1.2.3.4 becomes match out on $ext_if from 10/8 nat-to ($ext_if) match in on $ext_if to ($ext_if) rdr-to 1.2.3.4 and... binat on $ext_if from $web_serv_int to any -> $web_serv_ext becomes match on $ext_if from $web_serv_int to any binat-to $web_serv_ext nat-anchor and/or rdr-anchor lines, e.g. for relayd(8), ftp-proxy(8) and tftp-proxy(8), are no longer used and should be removed from pf.conf(5), leaving only the anchor lines. Translation rules relating to these and spamd(8) will need to be adjusted as appropriate. N.B.: Previously, translation rules had "stop at first match" behaviour, with binat being evaluated first, followed by nat/rdr depending on direction of the packet. Now the filter rules are subject to the usual "last match" behaviour, so care must be taken with rule ordering when converting. pf(4) route-to/reply-to syntax change The route-to, reply-to, dup-to and fastroute options in pf.conf move to filteropts; pass in on $ext_if route-to (em1 192.168.1.1) from 10.1.1.1 pass in on $ext_if reply-to (em1 192.168.1.1) to 10.1.1.1 becomes pass in on $ext_if from 10.1.1.1 route-to (em1 192.168.1.1) pass in on $ext_if to 10.1.1.1 reply-to (em1 192.168.1.1) Now, this is my current pf.conf: # $OpenBSD: pf.conf,v 1.38 2009/02/23 01:18:36 deraadt Exp $ # # See pf.conf(5) for syntax and examples; this sample ruleset uses # require-order to permit mixing of NAT/RDR and filter rules. # Remember to set net.inet.ip.forwarding=1 and/or net.inet6.ip6.forwarding=1 # in /etc/sysctl.conf if packets are to be forwarded between interfaces. ext_if="pppoe0" int_if="nfe0" int_net="192.168.0.0/24" polemon="192.168.0.10" poletopw="192.168.0.12" segatop="192.168.0.20" table <leechers> persist set loginterface $ext_if set skip on lo match on $ext_if all scrub (no-df max-mss 1440) altq on $ext_if priq bandwidth 950Kb queue {q_pri, q_hi, q_std, q_low} queue q_pri priority 15 queue q_hi priority 10 queue q_std priority 7 priq(default) queue q_low priority 0 nat-anchor "ftp-proxy/*" rdr-anchor "ftp-proxy/*" nat on $ext_if from !($ext_if) -> ($ext_if) rdr pass on $int_if proto tcp to port ftp -> 127.0.0.1 port 8021 rdr pass on $ext_if proto tcp to port 2080 -> $segatop port 80 rdr pass on $ext_if proto tcp to port 2022 -> $segatop port 22 rdr pass on $ext_if proto tcp to port 4000 -> $polemon port 4000 rdr pass on $ext_if proto tcp to port 6600 -> $polemon port 6600 anchor "ftp-proxy/*" block pass on $int_if queue(q_hi, q_pri) pass out on $ext_if queue(q_std, q_pri) pass out on $ext_if proto icmp queue q_pri pass out on $ext_if proto {tcp, udp} to any port ssh queue(q_hi, q_pri) pass out on $ext_if proto {tcp, udp} to any port http queue(q_std, q_pri) #pass out on $ext_if proto {tcp, udp} all queue(q_low, q_hi) pass out on $ext_if proto {tcp, udp} from <leechers> queue(q_low, q_std) pass in on $ext_if proto tcp to ($ext_if) port ident queue(q_hi, q_pri) pass in on $ext_if proto tcp to ($ext_if) port ssh queue(q_hi, q_pri) pass in on $ext_if proto tcp to ($ext_if) port http queue(q_hi, q_pri) pass in on $ext_if inet proto icmp all icmp-type echoreq queue q_pri If someone has experience with porting the 4.6 pf.conf to 4.7, please help me do the correct changes. OK, this is how far I've got: I commented out nat-anchor and rdr-anchor, as describted in the guide: #nat-anchor "ftp-proxy/*" #rdr-anchor "ftp-proxy/*" And this is how I've "converted" the rdr rules: #nat on $ext_if from !($ext_if) -> ($ext_if) match out on $ext_if from !($ext_if) nat-to ($ext_if) #rdr pass on $int_if proto tcp to port ftp -> 127.0.0.1 port 8021 match in on $int_if proto tcp to port ftp rdr-to 127.0.0.1 port 8021 #rdr pass on $ext_if proto tcp to port 2080 -> $segatop port 80 match in on $ext_if proto tcp tp port 2080 rdr-to $segatop port 80 #rdr pass on $ext_if proto tcp to port 2022 -> $segatop port 22 match in on $ext_if proto tcp tp port 2022 rdr-to $segatop port 22 rdr pass on $ext_if proto tcp to port 4000 -> $polemon port 4000 match in on $ext_if proto tcp tp port 4000 rdr-to $polemon port 4000 rdr pass on $ext_if proto tcp to port 6600 -> $polemon port 6600 match in on $ext_if proto tcp tp port 6600 rdr-to $polemon port 6600 Did I miss anything? Is the anchor for ftp-proxy OK as it is now? Do I need to change something in the other pass in on... lines?

• .NET SerialPort.Read skipps bytes

  - by Lukas Rieger

  Solution Reading the data byte wise via "port.ReadByte" is too slow, the problem is inside the SerialPort class. i changed it to reading bigger chunks via "port.Read" and there are now no buffer overruns. although i found the solution myself, writing it down helped me and maybe someone else has the same problem and finds this via google... (how can i mark it as answered?) EDIT 2 by setting port.ReadBufferSize = 2000000; i can delay the problem for ~30 seconds. so it seems, .Net really is too slow... since my application is not that critical, i just set the buffer to 20MB, but i am still interested in the cause. EDIT i just tested something i had not thought of before (shame on me): port.ErrorReceived += (object self, SerialErrorReceivedEventArgs se_arg) => { Console.Write("| Error: {0} | ", System.Enum.GetName(se_arg.EventType.GetType(), se_arg.EventType)); }; and it seems that i have an overrun. Is the .Net implementation too slow for 500k or is there an error on my side? Original Question i built a very primitive oszilloscope (avr, which sends adc data over uart to an ftdi chip). On the pc side i have a WPF Programm that displays this data. The Protokoll is: two sync bytes (0xaffe) - 14 data bytes - two sync bytes - 14 data bytes - ... i use 16bit values, so inside the 14 data bytes are 7 channels (lsb first). I verified the uC Firmware with hTerm, and it does send and receive everything correct. But, if i try to read the data with C#, sometimes some bytes are lost. The oszilloscop programm is a mess, but i created a small sample application, which has the same symptoms. I added two extension methods to a) read one byte from the COM Port and ignore -1 (EOF) and b) wait for the sync pattern. The sample programm first syncs onto the data stream by waiting for (0xaffe) and then compares the received bytes with the expected values. the loop runs a few times until an assert failed message pops up. I could not find anything about lost bytes via google, any help would be appreciated. Code using System; using System.Collections.Generic; using System.Diagnostics; using System.IO.Ports; using System.Linq; using System.Text; using System.Threading.Tasks; namespace SerialTest { public static class SerialPortExtensions { public static byte ReadByteSerial(this SerialPort port) { int i = 0; do { i = port.ReadByte(); } while (i < 0 || i > 0xff); return (byte)i; } public static void WaitForPattern_Ushort(this SerialPort port, ushort pattern) { byte hi = 0; byte lo = 0; do { lo = hi; hi = port.ReadByteSerial(); } while (!(hi == (pattern >> 8) && lo == (pattern & 0x00ff))); } } class Program { static void Main(string[] args) { //500000 8n1 SerialPort port = new SerialPort("COM3", 500000, Parity.None, 8, StopBits.One); port.Open(); port.DiscardInBuffer(); port.DiscardOutBuffer(); //Sync port.WaitForPattern_Ushort(0xaffe); byte hi = 0; byte lo = 0; int val; int n = 0; // Start Loop, the stream is already synced while (true) { //Read 7 16-bit values (=14 Bytes) for (int i = 0; i < 7; i++) { lo = port.ReadByteSerial(); hi = port.ReadByteSerial(); val = ((hi << 8) | lo); Debug.Assert(val != 0xaffe); } //Read two sync bytes lo = port.ReadByteSerial(); hi = port.ReadByteSerial(); val = ((hi << 8) | lo); Debug.Assert(val == 0xaffe); n++; } } } }

• Dell L501X Display Port Screen issue

  - by jdflorezPA

  I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200). I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right? Any ideas or suggestions would be appreciated. Thanks Using Ubuntu 11.10 32bit

• Port flash game to native android

  - by wirate

  Alright here is the problem: the creators of a quite popular flash-based game have asked me to port their game to Android. They are not interested in any other platforms so we don't need to be worrying about iOS or PC. They want the best performance on just Android (I guess that's the point of porting a flash-based game. They could have just went with it) They found Unity 'slow'. How would the performance (on android) of other engines compare? Are they expecting too much i.e. finding Unity slow? I am in favor of Unity since development is a little easier with more things being visual (I am not experienced as you might have guessed). This would be an example of the type of game I am to port Thanks!

• A Firefox extension for scan & upload document?

  - by Ivan Petrushev

  Hello, Do you know such an extension that provides easy document scanning in Firefox? We are building a web site and we want visitors to be able to upload scanned documents to it. The normal procedure for that is: Scan the document via Gimp, Photoshop or some other scanning software. Save the file. Navigate to the upload web page. Find some sort of HTML input type file on that page. Browse and find the saved file. Submit the form. I want an extension or plugin that automatize that process and do everything with 1 click - scan the document with some default settings (for example "grayscale, 300 dpi") creates temporary file, fills the page input field and deletes the temporary file after upload. I tried lots of googling but the term scan in combination with everything web-related gives zillions of virus, malware and port scanners...

• Utility for scanning stacks of double-sided documents

  - by Peter Becich

  I have a simplex scanner with document feeder, and am looking for the best way to scan double-sided notes. It would be useful to be able to scan the same stack twice, once flipped, and have a utility automatically interleave the scanned images. Multi-page PDF export would also be nice. Is there a tool to do this? Otherwise, I'm considering writing it in Python, with the imagescanner module, if it can use the ADF -- http://pypi.python.org/pypi/imagescanner/0.9 Thanks

• Stop Picasa (Mac) from scanning my harddrive

  - by Bodyscanner

  I want to use Picasa desktop app instead of the tedious & clunky web interface to share a couple of photos. Every time I launch Picasa it proceeds to open an annoying pop-up/tool-tip which flicks through every file on my HD using <=95% of CPU. I don't want this so I click the X. It appears again. I try to drag it somewhere less annoying onscreen but it pings back. I look in prefs for an option to turn it off. I give up and quit app until a new build comes out, which I download and repeat the above. WTF?! I understand Google can't be as cool as Apple - iPhoto isn't perfect by any means but at least it looks nice and 'just works'. I want to launch Picasa, not have it go through everything, not have 1000's of random pics and HD cruft on display in the list, and then perhaps drag in a few photos and upload them. Any idea of if that is possible? </rant>

  I have found that the local school's website installed a Perl Calendar - this was years ago, it has not been used for ages, but Google has it indexed (which is how I found it) and it full of Viagra links and the like ... program was by Matt Kruse, here is details of the exploit: http://www.securiteam.com/exploits/5IP040A1QI.html I've got the school to remove that, but I think they also have MySQL installed and I'm aware that out-of-the-box there have been some exploits of Admin Tools / Login in old versions. For all I know they also have PHPBB and the like installed ... The school is just using some cheap, shared hosting; the HTTP response header I get is: Apache/1.3.29 (Unix) (Red-Hat/Linux) Chili!Soft-ASP/3.6.2 mod_ssl/2.8.14 OpenSSL/0.9.6b PHP/4.4.9 FrontPage/5.0.2.2510 I'm looking for some means of checking if they have other junk installed (quite possibly from way back, and now unused) that might put the site at risk. I'm more interested in something that can scan for things like the MySQL Admin exploit rather than open ports etc. My guess is that they have little control over the hosting space that they have - but I'm a Windows DEV, so this *nix stuff is all Greek to me. I found http://www.beyondsecurity.com/ which looks like it might do what I want (within their evaluation :) ) but I have a worry about how to find out if they are well known / honest - otherwise I will be tipping them a wink with a Domain Name that may be at risk! Many thanks.

• Software for scanning installation process?

  - by no name

  I forgot what is the name of the very good software which make some kind of restore point (save registry, and program files folder, etc...) before installing any software. After you install some program (ie "Notepad++") you can easily see what registry data use new installed program, on what location are the file's is stored and many more. The reason that I'm asking for help is that I have to automate some installation of public software, so after installation I need to uninstall it, so i have to delete all junk files. The software is called something like install wizard, or wizard install I forgot. If you have any idea of other application that do same thing , or you know exactly name of that software, or you have some good idea how to solve easy solve many installation and uninstallation, please let me know. Os: win7/xp 64/32
