  • who uses a TCP port?

    - by dijxtra
    One of gen_servers in my app call gen_tcp:listen(Port, [{active, true}]). First time I run unit test, it returns {ok, Socket}, but second time I run the same unit test, it returns an {error, eaddrinuse}, but lsof -i TCP returns nothing. Also, when the same unit_test is run twice on another machine (WinXP), it works as expected (that is, returns {ok, Socket} both times). Therefore, my gen_server obviously releases the port, but Erlang somehow doesn't know that. So, how can I figure out who does Erlang think uses this address?

  • sending data to the server via port 5555 C#

    - by numerical25
    I am wanting to send some data to a server from a client application to the server via port 5555. I don't have a window's server. My question is if I purchase a .Net Framework hosting service. Would I be able to connect the client application to this server. and could I do it by sending a Post. I am new to this, so excuse me if it doesn't entire make sense. but I am looking for just some little direction. If someone could explain what port 5555 is used for that would be great.

  • Dispatcher.CheckAccess() isn't working from my console application, is there a better way.

    - by zimmer62
    I wrote an application in WPF / VB and separated the business logic and UI into different projects. The business layer uses a serial port which runs on a different thread, Now that I'm trying to write a command line interface for the same business layer, it seems to fail when .Invoke() is called. (no error, just doesn't work) I'm pretty sure the reason I had to add in checkaccess and .invoke was because I have collections that would be changed during processing the serial port data and wanted the NotifyCollectionChanged to be handled by WPF data binding. (The reason I'm not 100% sure is because it was months ago I wrote that part and it all worked great from the GUI, now adding the console app has made me rethink some of this) I would like my business layer to run these processes on the thread they were created, I need this to work from both my GUI version and the command line version. Am I misusing the Dispatcher in my business layer? Is there a better way to handle an event from the serial port, and then return to the main thread to processes the data?

  • Close TCP port 80 and 443 after forking in Django

    - by audiodev
    I am trying to fork() and exec() a new python script process from within a Django app that is running in apache2/WSGI Python. The new python process is daemonized so that it doesn't hold any association to apache2, but I know the HTTP ports are still open. The new process kills apache2, but as a result the new python process now holds port 80 and 443 open, and I don't want this. How do I close port 80 and 443 from within the new python process? Is there a way to gain access to the socket handle descriptors so they can be closed?

  • Optimizing AES modes on Solaris for Intel Westmere

    - by danx
    Optimizing AES modes on Solaris for Intel Westmere Review AES is a strong method of symmetric (secret-key) encryption. It is a U.S. FIPS-approved cryptographic algorithm (FIPS 197) that operates on 16-byte blocks. AES has been available since 2001 and is widely used. However, AES by itself has a weakness. AES encryption isn't usually used by itself because identical blocks of plaintext are always encrypted into identical blocks of ciphertext. This encryption can be easily attacked with "dictionaries" of common blocks of text and allows one to more-easily discern the content of the unknown cryptotext. This mode of encryption is called "Electronic Code Book" (ECB), because one in theory can keep a "code book" of all known cryptotext and plaintext results to cipher and decipher AES. In practice, a complete "code book" is not practical, even in electronic form, but large dictionaries of common plaintext blocks is still possible. Here's a diagram of encrypting input data using AES ECB mode: Block 1 Block 2 PlainTextInput PlainTextInput | | | | \/ \/ AESKey-->(AES Encryption) AESKey-->(AES Encryption) | | | | \/ \/ CipherTextOutput CipherTextOutput Block 1 Block 2 What's the solution to the same cleartext input producing the same ciphertext output? The solution is to further process the encrypted or decrypted text in such a way that the same text produces different output. This usually involves an Initialization Vector (IV) and XORing the decrypted or encrypted text. As an example, I'll illustrate CBC mode encryption: Block 1 Block 2 PlainTextInput PlainTextInput | | | | \/ \/ IV >----->(XOR) +------------->(XOR) +---> . . . . | | | | | | | | \/ | \/ | AESKey-->(AES Encryption) | AESKey-->(AES Encryption) | | | | | | | | | \/ | \/ | CipherTextOutput ------+ CipherTextOutput -------+ Block 1 Block 2 The steps for CBC encryption are: Start with a 16-byte Initialization Vector (IV), choosen randomly. XOR the IV with the first block of input plaintext Encrypt the result with AES using a user-provided key. The result is the first 16-bytes of output cryptotext. Use the cryptotext (instead of the IV) of the previous block to XOR with the next input block of plaintext Another mode besides CBC is Counter Mode (CTR). As with CBC mode, it also starts with a 16-byte IV. However, for subsequent blocks, the IV is just incremented by one. Also, the IV ix XORed with the AES encryption result (not the plain text input). Here's an illustration: Block 1 Block 2 PlainTextInput PlainTextInput | | | | \/ \/ AESKey-->(AES Encryption) AESKey-->(AES Encryption) | | | | \/ \/ IV >----->(XOR) IV + 1 >---->(XOR) IV + 2 ---> . . . . | | | | \/ \/ CipherTextOutput CipherTextOutput Block 1 Block 2 Optimization Which of these modes can be parallelized? ECB encryption/decryption can be parallelized because it does more than plain AES encryption and decryption, as mentioned above. CBC encryption can't be parallelized because it depends on the output of the previous block. However, CBC decryption can be parallelized because all the encrypted blocks are known at the beginning. CTR encryption and decryption can be parallelized because the input to each block is known--it's just the IV incremented by one for each subsequent block. So, in summary, for ECB, CBC, and CTR modes, encryption and decryption can be parallelized with the exception of CBC encryption. How do we parallelize encryption? By interleaving. Usually when reading and writing data there are pipeline "stalls" (idle processor cycles) that result from waiting for memory to be loaded or stored to or from CPU registers. Since the software is written to encrypt/decrypt the next data block where pipeline stalls usually occurs, we can avoid stalls and crypt with fewer cycles. This software processes 4 blocks at a time, which ensures virtually no waiting ("stalling") for reading or writing data in memory. Other Optimizations Besides interleaving, other optimizations performed are Loading the entire key schedule into the 128-bit %xmm registers. This is done once for per 4-block of data (since 4 blocks of data is processed, when present). The following is loaded: the entire "key schedule" (user input key preprocessed for encryption and decryption). This takes 11, 13, or 15 registers, for AES-128, AES-192, and AES-256, respectively The input data is loaded into another %xmm register The same register contains the output result after encrypting/decrypting Using SSSE 4 instructions (AESNI). Besides the aesenc, aesenclast, aesdec, aesdeclast, aeskeygenassist, and aesimc AESNI instructions, Intel has several other instructions that operate on the 128-bit %xmm registers. Some common instructions for encryption are: pxor exclusive or (very useful), movdqu load/store a %xmm register from/to memory, pshufb shuffle bytes for byte swapping, pclmulqdq carry-less multiply for GCM mode Combining AES encryption/decryption with CBC or CTR modes processing. Instead of loading input data twice (once for AES encryption/decryption, and again for modes (CTR or CBC, for example) processing, the input data is loaded once as both AES and modes operations occur at in the same function Performance Everyone likes pretty color charts, so here they are. I ran these on Solaris 11 running on a Piketon Platform system with a 4-core Intel Clarkdale processor @3.20GHz. Clarkdale which is part of the Westmere processor architecture family. The "before" case is Solaris 11, unmodified. Keep in mind that the "before" case already has been optimized with hand-coded Intel AESNI assembly. The "after" case has combined AES-NI and mode instructions, interleaved 4 blocks at-a-time. « For the first table, lower is better (milliseconds). The first table shows the performance improvement using the Solaris encrypt(1) and decrypt(1) CLI commands. I encrypted and decrypted a 1/2 GByte file on /tmp (swap tmpfs). Encryption improved by about 40% and decryption improved by about 80%. AES-128 is slighty faster than AES-256, as expected. The second table shows more detail timings for CBC, CTR, and ECB modes for the 3 AES key sizes and different data lengths. » The results shown are the percentage improvement as shown by an internal PKCS#11 microbenchmark. And keep in mind the previous baseline code already had optimized AESNI assembly! The keysize (AES-128, 192, or 256) makes little difference in relative percentage improvement (although, of course, AES-128 is faster than AES-256). Larger data sizes show better improvement than 128-byte data. Availability This software is in Solaris 11 FCS. It is available in the 64-bit libcrypto library and the "aes" Solaris kernel module. You must be running hardware that supports AESNI (for example, Intel Westmere and Sandy Bridge, microprocessor architectures). The easiest way to determine if AES-NI is available is with the isainfo(1) command. For example, $ isainfo -v 64-bit amd64 applications pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tsc fpu No special configuration or setup is needed to take advantage of this software. Solaris libraries and kernel automatically determine if it's running on AESNI-capable machines and execute the correctly-tuned software for the current microprocessor. Summary Maximum throughput of AES cipher modes can be achieved by combining AES encryption with modes processing, interleaving encryption of 4 blocks at a time, and using Intel's wide 128-bit %xmm registers and instructions. References "Block cipher modes of operation", Wikipedia Good overview of AES modes (ECB, CBC, CTR, etc.) "Advanced Encryption Standard", Wikipedia "Current Modes" describes NIST-approved block cipher modes (ECB,CBC, CFB, OFB, CCM, GCM)

  • DNS Server Behind NAT

    - by Bryan
    I've got a Bind 9 DNS server sitting behind a NAT firewall, assume the Internet facing IP is 1.2.3.4 There are no restrictions on outgoing traffic, and port 53 (TCP/UDP) is forwarded from 1.2.3.4 to the internal DNS server (10.0.0.1). There are no IP Tables rules on either the VPS or the internal Bind 9 server. From a remote Linux VPS located elsewhere on the internet, nslookup works fine # nslookup foo.example.com 1.2.3.4 Server: 1.2.3.4 Address: 1.2.3.4#53 Name: foo.example.com Addresss: 9.9.9.9 However, when using the host command on the remote VPS, I receive the following output: # host foo.example.com 1.2.3.4 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; connection timed out; no servers could be reached.

  • CSS IE Hover Effect - Overlapping Elements, Display:Block, and Crashes

    - by Emtucifor
    In a fairly simple page, I have some text appear on hover over some links, like a tooltip. To start with here's my test page I'm working with: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Tooltip Test Page</title> <style type="text/css"> html, body, form, table, tr, td, div, p, h1, h2, h3, h4, h5 { border:0; margin:0; padding:0; } body { margin:10px; } html, body, table { font-family:Arial, Helvetica, sans-serif; font-size:12px; } h1 { font-weight:bold; font-size:16px; } table {border-collapse:collapse;} td {padding:0 8px 0 0;} a.tooltip { z-index:24; text-decoration:none; cursor:default; position:relative; color:#000; display:block; width:100px; } a.tooltip span {display:none;} a.tooltip:hover, a.tooltip:active { z-index:25; color:; background:; /* the color and background actually don't matter for their values, it's just that these have to change for IE to apply this style properly. Leaving out the color or the background makes this fail in different ways. */ } a.tooltip:hover span, a.tooltip:active span { display:block; position:absolute; color:black; background-color:#FFFFCC; border:1px solid black; padding:1px; text-align:left; top:0; left:0; margin-top:-1px; } td span.s5 {color:#ff0000} td span.s6 {color:#0000ff} </style> <script type="text/javascript"> function labelSubmit(label) { document.getElementById('o').value=label; document.BackAt.submit(); } </script> </head> <body> <h1>tooltip Test Page</h1> <table> <tbody> <tr> <td><span class="s6">&#x25a0;</span> Name 3</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some very long tooltip text to demonstrate the problem by overlapping the cells below.</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 1</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 2</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some tooltip text</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 4</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s5">&#x25a0;</span> Name 5</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 5<span>More Notes</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 6</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Yet more notes</span></a></td> </tr> </tbody> </table> </body> </html> The problem I'm experiencing is that text from other values shows through the tooltip text. Hover over the first row, second column to see the effect. There are a couple of things I'm trying to accomplish: Make the activation area for the hover wider, so hovering over some space to the right of "Status 6" calls up the tooltip (say, 100-150px total width of target). At first, when I was adding "display:block" to a.tooltip, IE was terminating on hover. I resolved that by removing width:14em from a.tooltip:hover. Styling the width of the hover event + display.block on the a element does BAD things. Change the width of the tooltip without changing the width of the column/parent element (so the tooltip can be wider than itso it takes up less vertical space). Options for making the tooltips change width with its contents up to a max width, at which point the lines wrap would be awesome, but probably impossible in IE. As soon as I put a width in place on a.tooltip, the portion of the tooltip that is above other rows than the hover source let text show through from those cells. Remove the width and you'll see that the text doesn't show through any more. The hover effect applies to the entire tooltip, so if the tooltip covers 3 rows, while moving the mouse downward, the next 2 rows won't activate because the cursor hasn't left the tooltip. Can the hover effect apply only to the initial element hovered over and not the tooltip itself so moving the mouse downward will show each tooltip in each row? It would be nice if the links could never be activated (they can't take the focus). I don't know if that's possible. Too bad IE doesn't support hover on any elements but links. Note: soon IE6 will be abandoned in favor of IE8. If it makes a big difference, then IE8 can be the target browser instead. Thanks for your help.

  • Untrusted file not showing unblock button windows 7

    - by Stewart Griffin
    I downloaded a dll but cannot use it as it is considered untrusted. I opened it using: Notepad.exe filepath\filename:zone.identifier and it informed me that that the file was in zone 3. Despite this I do not get an unblock button in the properties page for the file. Not being able to unblock it with this button I instead changed the value in notepad and saved my changes. When I reopen the zone.identifier info it is as I left it. I have set it to both 2 (trusted) and 0 (no information), but still am unable to use the files. Any one have any ideas? If I cannot unblock the files I will investigate turning this blocking off, but as a first step I'd like to try and just unblock this one file. Note: using Windows 7 Ultimate edition. It is when using MSTest from within Visual Studio 2008 that I hit problems.

  • Continual "The Windows Filtering Platform has blocked a connection" errors?

    - by Richard
    Our systems have been compromised by something recently which has lead us to carry out a more detailed look at what is happening on our workstations. I have noticed an issue where the Security log of this Windows 7 workstation is continually logging a security "Audit Failure" where the detail is that "The Windows Filtering Platform has blocked a connection". This is happening thousands of times a day and would appear to be our BT Business Broadband HGV 2700 ADSL router attempting to connect to Port 137 (NET Bios) on my workstation and being blocked. This has unfortunately had the effect of filling up the log files so much that anything which might have been of use which was logged over the weekend to help debug the intrusion has been "overwritten off the end" of the Security log. (I've since increased the log file size limits massively and turned on archiving). Does anyone know if this is standard behaviour of a BT ADSL router or whether this indicates that the router is compromised in some way or malfunctioning, or have any further suggestions as to how to diagnose this problem?

  • Group Policy: Block access to \\localhost\C$

    - by Ryan R
    We have a restricted Windows 7 computer that hides and prevents non-admin users from accessing the C Drive. However, they are able to circumvent this by typing the following into Explorer: \\localhost\C$ How can I disable this path but allow other UNC paths. For example they are allowed to access a shared folder on a different computer. eg. \\192.168.2.1\SharedTransfer Note: Simply Enabling the Group Policy: Remove Run menu from Start Menu will not work as this blocks all UNC paths.

  • Tunneling a TCP/IP Connection through Remote Desktop Connection

    - by Kristopher Johnson
    There is a remote Windows server on a private network which I can connect to via Remote Desktop Connection. I would like to be able to make TCP/IP connections from my computer to other computers on that server's network. Remote Desktop Connection makes it possible to share printers, drives, and other local resources through the connection. Is there any way to "tunnel" a TCP/IP connection via RDC? I'd like something similar to the port-forwarding provided by SSH. I don't see any way to do this via RDC, but I'm hoping the capability is there and I just don't know about it.

  • Cisco Spam Blocker, Iron Port, Lotus Domino, Integration Help

    - by NickToyota
    Hi serverfault universe, I work for a medium sized (roughly 200 user) company. We are attempting to intagrate our new Cisco Spam Video Blocker (ironport) device into our network so that it acts as an incoming filter then passes it off to our Lotus domino mail server. And also vise versa. The way our network is setup currently has an mx record pointing to our Domino mail SMTP incoming server which is currently setup to be an inbound gateway and filter (using symantec domino mail software). We want to replace the inbound gateway with the ironport. Our company has also invested in a pool of external IP addresses which I believe has been currently assigned to our web, email, servers. What would the proper course of action be to successfully integrate the device be? Mx record change? Replace the domino gateway completely with the ironport? We attempted to set the ironport device to the external IP of what our mx record is pointing to without much success. Any help on proper setup would be greatly appreciated.

  • should i bother to block these- rather lame attempt at hacking my server

    I'm running a LAMP stack, with no phpmyadmin (yes) installed. While poking through my apache server longs i noticed things like. 74.208.75.29 - - [16/Mar/2010:02:53:45 +0800] "POST http://74.208.75.29:6667/ HTTP/1.0" 404 481 "-" "-" 74.208.75.29 - - [16/Mar/2010:02:53:45 +0800] "CONNECT 74.208.75.29:6667 HTTP/1.0" 405 547 "-" "-" 66.184.178.58 - - [16/Mar/2010:13:27:59 +0800] "GET / HTTP/1.1" 200 1170 "-" "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)" 200.78.247.148 - - [16/Mar/2010:15:26:05 +0800] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 506 "-" "-" 206.47.160.224 - - [16/Mar/2010:17:27:57 +0800] "GET / HTTP/1.1" 200 1170 "-" "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:02 +0800] "GET //phpmyadmin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 480 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:03 +0800] "GET //pma/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 476 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:04 +0800] "GET //admin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 478 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:05 +0800] "GET //dbadmin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 479 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:05 +0800] "GET //mysql/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 479 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:06 +0800] "GET //php-my-admin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 482 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" What exactly is happening? is it a really lame attempt at hacking in? Should i bother blocking the ip addresses these are from, or just leave it?

  • Can Windows-Security-SPP block execution of .exe?

    - by Kirk Marple
    We're seeing a strange situation, where some executables won't run from a Windows command prompt (running as admin). Just running the command (say, filename.exe) gives no response on the console. No errors, no output, nothing. If we copy over the same Windows .exe from a different folder, it "magically" starts working, and we see the default console output. (Happens both on Win7 x64, and Win2008R2 x64. Application is running as 32-bit process.) At the time when it accesses the .exe, I can see events in the application and system logs regarding Windows-Security-SPP, and it makes me believe that the .exe is being blocked from execution. Does this sound familiar?

  • Block all but http traffic on a network interface

    - by Oli
    I've got two network interfaces on an Ubuntu machine which go out to two different networks but both have internet gateways. I need to limit it so that any outgoing http requests it makes (ie through wget) only go through eth0 and all other traffic goes through eth1. I dare say the solution might have something to do with iptables but I've no experience with it so would appreciate all help.

  • HP DL360 G6 NC328i Dual Port Gigabit - Windows Server 2003 R2 Driver Problem

    - by brianjd
    I recently installed Windows Server 2003 R2 (64) on a DL360 G6 without using the SmartStart CD (it didn't like the MSDN media). But when I attempted to install the network drivers post-install using the packages from the HP website, I wasn't successful. Though I selected the correct package, the installer reported I did not have the necessary hardware configuration. Has anyone had a similar experience? Thanks

  • How to know which block device maps to which physical drive

    - by Karolis T.
    I have a server with software RAID 1, two hot-swap sata disks. One hard drive started showing errors, I'm thinking about removing and replacing it, only problem is that I have no idea which of the two correspond to which devices. And I can't shut the server down to find out. I have /dev/sda and /dev/sdb, /dev/sda is the failing one. Thought about doing something along the lines # mdadm --manage /dev/md0 --remove /dev/sda1 then somehow stop/suspend the drive using tuning software and try to listen which of the two stopped, but that's not gonna work in a noisy server environment. Drive panels have no LEDs. Thanks for any ideas!

  • Forwarding MySQL connection with iptables and differents network interfaces

    - by Emilio Nicolás
    I have a PC with Ubuntu as a router. It has a 3G connection with a public IP to the Internet, and there is a private wireless subnet. So it has two active interfaces: ppp0: public IP (WAN) wlan0: private IP (LAN) With iptables I wannt to forward every MySQL connection (port 3306) to a local machine (10.42.43.10) of the subnet. I type these iptables commands: iptables -A PREROUTING -t nat -i ppp0 -p tcp --dport 3306 -j DNAT --to 10.42.43.10:3306 iptables -A FORWARD -p tcp -i ppp0 -o wlan0 -d 10.42.43.10 --dport 3306 -j ACCEPT But it doesn't work. telnet publicip 3306 fails :-( Any help will be appreciated. Thanks!

  • Make Apache to listen in multiple IPs

    - by Enrique Becerra
    Hi I'm in a big LAN, which is behind a proxy/firewall I'm working with an apache/php/mysql application, which is hosted in a small server besides my workstation. This server is connected to the LAN also and is behind the proxy: The server has a local IP assigned: 10.64.x.x Also, this server has a public IP assigned (or redirected from within the proxy/firewall) which is: 200.41.x.x I can't access public IP from LAN, but I can ping to the public IP from outside the building How should I configure Apache to listen also for public IP and open the 80 port for people accessing from outside the building?. It is set now to Listen 10.64.x.x:80 Thanks a lot in advance,
