• Logins with only HTTP - are they as insecure as I'm thinking?

  - by JoeCool1986

  Recently I was thinking about how websites like gmail and amazon use HTTPS during the login process when accessing your account. This makes sense, obviously, since you're typing in your account username and password and you would want that to be secure. However, on Facebook, among countless other websites, their logins are done with simple HTTP. Doesn't that mean that my login name and password are completely unencrypted? Which, even worse, means that all those people who login to their facebooks (or similar sites) at a wifi hotspot in public are susceptible to anyone getting their credentials using a simple packet sniffer (or something similar)? Is it really that easy? Or am I misunderstanding internet security? I'm a software engineer working on some web related stuff, and although at the current time I'm not too involved with the security aspect of our software, I knew I should probably know the answer to this question, since it's extremely fundamental to website security. Thanks!

• In Wireshark's Protocol Hierarchy Statistics screen, is the total byte count of a capture the sum of the Bytes column or just the top line (Frame)?

  - by Howiecamp

  Part 1 - I'm looking at Wireshark's Protocol Hierarchy Statistics screen (sample below), is the total byte count of the capture the sum of the Bytes column or just the top line (Frame)? I'm 99% that it's the latter because of protocol rollup but I wanted to conform. Part 2 - From Wireshark documentation on this screen, "Protocol layers can consist of packets that won't contain any higher layer protocol, so the sum of all higher layer packets may not sum up to the protocols packet count. Example: In the screenshot TCP has 85,83% but the sum of the subprotocols (HTTP, ...) is much less. This may be caused by TCP protocol overhead, e.g. TCP ACK packets won't be counted as packets of the higher layer)." Can you explain this?

• compromised site

  - by pinniger

  So, I have a web site that has been compromised twice in two weeks. every index.php and .js file gets a script injecting into the source code of the file. The problem is that I have no idea how they're doing it. I've seen this done via sql injection before, but I don't know how they are actually writing to the file. I've dug through the Apache logs but didn't find anything interesting. The site is built using the cakephp framework on a godaddy shared server. Anybody know what secturity settings or log files to check to see how they are doing this?

• Wireshark Display Filter protocol==TLSV1? (and PacketLength)

  - by NealWalters

  What would the filter expression be to just select the protocols where the protocol = TLSV1? Something obvious like protocol == "TLSV1" or TCP.protocol == "TLSV1" is apparently not the right way. ip.proto == "TLSV1" says "ip.proto cannot accept strings as values" Update - additional tips: Another great but hidden search is on PacketLength: You can add packet length to your display by clicking "Edit Preferences" (menu or icon), and adding the PacketLength as a new column, but to filter on it you have to use the more cryptic: frame.len == ### where ### is your desired number. We were using this to determine how many packets had been sent and/or received, when you filter, the status-bar at the bottom of the screen shows the number of items matching the filter.

• Redirect with iptables if destination port is not listened

  - by PoltoS

  I've a server listening on port 10000. But this server is running only in a special case (then some third service is available). Otherwise the port is not listened. Is it possible to redirect the client to another port if 10000 is not listening? I see two solutions: 1) insert/remove iptables rules on server start/stop, but since the server may be killed, it may not insert the correct iptable redirect rule before dieing. 2) make a permanent userspace rule that checks if the port is listening and redirects the packet if not listened. How to do 2) ? Do someone have recipes for ipq? May be someone can suggest me a better way? It is something like fallback redirect: I'll have thousand of clients with different ports (10000-11000) and if their instance of server is not running, whey should be redirected to some page explaining why they don't have and instance connected.

• How to retrieve connection details of CheckPoint SSL Network Extender?

  - by amoe

  My workplace uses a Java-based VPN tool named CheckPoint SSL Network Extender. I would like to configure the VPN connection myself using stock OS tools, because I find the applet to be rather unstable. How would I go about getting all of the connection details needed to manually connect to the VPN? My workplace only supports the official client. When I am connected with the Java applet, if I run ipconfig /all I can see that a hidden network connection is created named Check Point Virtual Network Adapter For SSL Network Extender - Packet Scheduler Miniport. I can see the various IP and DNS details there as well. However, because I need to log in to the applet-based tool, I presume I need to export some kind of key in order to use OS tools to configure this. Is this even possible? Answers for any OS are great although I am using Windows XP to test, and also want to use Linux clients.

• How to run wireshark on the background without the GUI?

  - by user60968

  Hello everybody, I am trying to run Wireshark on Mac OS X, on the background. I did install the command line utilities, and so I am able to start wireshark and capture packet using the command line. The only thing I want now is to run it on the background, without even having the X11 icon on the task bar and see the window of wireshark. I believe it is possible but can't find anything on the doc of Wireshark. Maybe another way would be to find a trick to hide an icon on Mac OS X... If anybody already did that or have an idea... Thank you Please excuse my English which is not perfect at all

• LAN full of public ipv4 addresses - How to filter it?

  - by sparc86

  The answer to my question maybe is not that hard but anyways, I do not know what to do. So, I just got in a new job in a Univerisity and I found out that the network (the LAN) is full of public IP addresses. Seriously, the whole LAN (probably more than 150 hosts) has it' own internet IP address and I don't know how to manage it. I have a very good experience using iptables (Linux firewall) in a NAT'ed environment. But then how should I proceed in an environment where all my LAN is working with a bunch of public IP addresses? Should I just use the "forward" rules and ignore the NAT rules or is there any other issue in such environment which I should take care? Can I add a firewall between the router and the LAN in order to produce packet filtering for these public IP addresses in my LAN or will this just not work? Thanks!

• Can OpenVPN be set up so the server doesn't have interface that is part of the VPN?

  - by BCS

  I'm looking to set up a VPN (OpenVPN is my first choice but I'm not stuck with it) in such a way that the server that hosts the VPN is not visible from within the VPN. That is; any packet that a client sends via the VPN interface will get delivered to another client's VPN interface or get dropped. In the other direction, the server shouldn't have a VPN interface at all and normal network operations shouldn't be able to send packets on the network. Can this be done? All the docs I have found have assumed that clients will connect via DHCP (this requiring that the server connect at least to that extent) but I can't think of any reason that a VPN couldn't use static IP's or that the DHCP server couldn't be implemented inside the VPN (see edit) server without setting up a VPN interface on the server. Edit: Based on the link on bridged mode from Phil Hollenback's answer it seems that OpenVPN does in fact have the "internal DHCP server" that I'm thinking of.

• Apache not responding in amazon ec2

  - by Viren

  Well this might sound awkward but I facing terrible issue with my Amazon EC2 instance one of the finding I see is that apache is not responding on port 80 which is weird because I can't even find the incoming packet to port 80 in tcpdump output As per the security rules all security rules are in place correctly at least in amazon console I restarted the apache to listen to port 8080 and added port 8080 and add 8080 to security rule and everything work but I cant just able to understand as to why the port 80 not responding Needless to say since port 8080 is responding all my CNAME and A-record is working too UPDATE No firewall issue either I just cross check the iptables and list is empty Can some share a light on this

• Wireshark TCP Window Size Value

  - by T Vernon

  I am debugging an application with Wireshark and watching the TCP Window Size value shrink on one side of the communication. If the packet's TCP section shows a "Window size value: 1", does that mean the source's window size is 1 or the destination's window size is 1? I know one side is communicating faster than the other can handle, I just want be sure I know which one it is. 1 192.168.0.1 - 192.168.0.100, Modbus/TCP, Length: 66, Window Size Value: 1 2 192.168.0.100 - 192.168.0.1, TCP, Length: 60, Window Size Value: 92 3 192.168.0.100 - 192.168.0.1 TCP, Length: 310, Window Size Value: 92 4 192.168.0.1 - 192.168.0.100 TCP, Length: 54, Window Size Value: 0 So is 192.168.0.1's window size 0 or is it reporting that 192.168.0.100's window is 0? Thanks.

• Cannot connect to MySQL with JDBC - Connection Timeout - Ubuntu 9.04

  - by gav

  I am running Ubuntu and am ultimately trying to connect Tomcat to my MySQL database using JDBC. It has worked previously but after a reboot the instance now fails to connect. Both Tomcat 6 and MySQL 5.0.75 are on the same machine Connection string: jdbc:mysql:///localhost:3306 I can connect to MySQL on the command line using the mysql command The my.cnf file is pretty standard (Available on request) has bind address: 127.0.0.1 I cannot Telnet to the MySQL port despite netstat saying MySQL is listening I have one IpTables rule to forward 80 - 8080 and no firewall I'm aware of. I'm pretty new to this and I'm not sure what else to test. I don't know whether I should be looking in etc/interfaces and if I did what to look for. It's weird because it used to work but after a reboot it's down so I must have changed something.... :). I realise a timeout indicates the server is not responding and I assume it's because the request isn't actually getting through. I installed MySQL via apt-get and Tomcat manually.

• Is this PHP/MySQL login script secure?

• Database connection timeout

  Hi I have read so many articles on the Internet about this problem but none seem to have a clear solution. Please could someone give me a definite answer as to why I am getting database timeouts.

• Play! Framework 1.2.4 --- C3P0 settings to avoid Communications link failure do to idle time

  - by HelpMeStackOverflowMyOnlyHope

  I'm trying to customize my C3P0 settings to avoid the error shown at the bottom of this post. It was suggested at this url --- http://make-it-open.blogspot.com/2008/12/sql-error-0-sqlstate-08s01.html --- to adjust the settings as follows: In hibernate.cfg.xml, write <property name="c3p0.min_size">5</property> <property name="c3p0.max_size">20</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statements">50</property> Then create "c3p0.properties" in your root classpath folder and write c3p0.testConnectionOnCheckout=true c3p0.acquireRetryDelay=1000 c3p0.acquireRetryAttempts=1 I've tried to make those adjustments following the direction of the Play! Framework documentation, where they say use "db.pool..." as follows: db.pool.timeout=1800 db.pool.maxSize=15 db.pool.minSize=5 db.pool.initialSize=5 db.pool.acquireRetryAttempts=1 db.pool.preferredTestQuery=SELECT 1 db.pool.testConnectionOnCheckout=true db.pool.acquireRetryDelay=1000 db.pool.maxStatements=50 Are those settings not going to work? Should I be trying to set them in a different way? With those settings I still get the error shown below, that is due to to long of a idle time.

• Problems with Asynchronous UDP Sockets

  - by ihatenetworkcoding

  Hi, I'm struggling a bit with socket programming (something I'm not at all familiar with) and I can't find anything which helps from google or MSDN (awful). Apologies for the length of this. Basically I have an existing service which recieves and responds to requests over UDP. I can't change this at all. I also have a client within my webapp which dispatches and listens for responses to that service. The existing client I've been given is a singleton which creates a socket and an array of response slots, and then creates a background thread with an infinite looping method that makes "sock.Receive()" calls and pushes the data received into the slot array. All kinds of things about this seem wrong to me and the infinite thread breaks my unit testing so I'm trying to replace this service with one which makes it's it's send/receives asynchronously instead. Point 1: Is this the right approach? I want a non-blocking, scalable, thread-safe service. My first attempt is roughly like this, which sort of worked but the data I got back was always shorter than expected (i.e. the buffer did not have the number of bytes requested) and seemed to throw exceptions when processed. private Socket MyPreConfiguredSocket; public object Query() { //build a request this.MyPreConfiguredSocket.SendTo(MYREQUEST, packet.Length, SocketFlags.Multicast, this._target); IAsyncResult h = this._sock.BeginReceiveFrom(response, 0, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), this._sock); if (!h.AsyncWaitHandle.WaitOne(TIMEOUT)) { throw new Exception("Timed out"); } //process response data (always shortened) } private void ARecieve (IAsyncResult result) { int bytesreceived = (result as Socket).EndReceiveFrom(result, ref this._target); } My second attempt was based on more google trawling and this recursive pattern I frequently saw, but this version always times out! It never gets to ARecieve. public object Query() { //build a request this.MyPreConfiguredSocket.SendTo(MYREQUEST, packet.Length, SocketFlags.Multicast, this._target); State s = new State(this.MyPreConfiguredSocket); this.MyPreConfiguredSocket.BeginReceiveFrom(s.Buffer, 0, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), s); if (!s.Flag.WaitOne(10000)) { throw new Exception("Timed out"); } //always thrown //process response data } private void ARecieve (IAsyncResult result) { //never gets here! State s = (result as State); int bytesreceived = s.Sock.EndReceiveFrom(result, ref this._target); if (bytesreceived > 0) { s.Received += bytesreceived; this._sock.BeginReceiveFrom(s.Buffer, s.Received, BUFFER_SIZE, SocketFlags.None, ref this._target, new AsyncCallback(ARecieve), s); } else { s.Flag.Set(); } } private class State { public State(Socket sock) { this._sock = sock; this._buffer = new byte[BUFFER_SIZE]; this._buffer.Initialize(); } public Socket Sock; public byte[] Buffer; public ManualResetEvent Flag = new ManualResetEvent(false); public int Received = 0; } Point 2: So clearly I'm getting something quite wrong. Point 3: I'm not sure if I'm going about this right. How does the data coming from the remote service even get to the right listening thread? Do I need to create a socket per request? Out of my comfort zone here. Need help.

• Update on ASP.NET MVC 3 RC2 (and a workaround for a bug in it)

  - by ScottGu

  Last week we published the RC2 build of ASP.NET MVC 3.  I blogged a bunch of details about it here. One of the reasons we publish release candidates is to help find those last “hard to find” bugs. So far we haven’t seen many issues reported with the RC2 release (which is good) - although we have seen a few reports of a metadata caching bug that manifests itself in at least two scenarios: Nullable parameters in action methods have problems: When you have a controller action method with a nullable parameter (like int? – or a complex type that has a nullable sub-property), the nullable parameter might always end up being null - even when the request contains a valid value for the parameter. [AllowHtml] doesn’t allow HTML in model binding: When you decorate a model property with an [AllowHtml] attribute (to turn off HTML injection protection), the model binding still fails when HTML content is posted to it. Both of these issues are caused by an over-eager caching optimization we introduced very late in the RC2 milestone.  This issue will be fixed for the final ASP.NET MVC 3 release.  Below is a workaround step you can implement to fix it today. Workaround You Can Use Today You can fix the above issues with the current ASP.NT MVC 3 RC2 release by adding one line of code to the Application_Start() event handler within the Global.asax class of your application: The above code sets the ModelMetaDataProviders.Current property to use the DataAnnotationsModelMetadataProvider.  This causes ASP.NET MVC 3 to use a meta-data provider implementation that doesn’t have the more aggressive caching logic we introduced late in the RC2 release, and prevents the caching issues that cause the above issues to occur.  You don’t need to change any other code within your application.  Once you make this change the above issues are fixed.  You won’t need to have this line of code within your applications once the final ASP.NET MVC 3 release ships (although keeping it in also won’t cause any problems). Hope this helps – and please keep any reports of issues coming our way, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

• Free Video Training: ASP.NET MVC 3 Features

  - by ScottGu

  A few weeks ago I blogged about a great ASP.NET MVC 3 video training course from Pluralsight that was made available for free for 48 hours for people to watch.  The feedback from the people that had a chance to watch it was really fantastic.  We also received feedback from people who really wanted to watch it – but unfortunately weren’t able to within the 48 hour window. The good news is that we’ve worked with Pluralsight to make the course available for free again until March 18th.  You can watch any of the course modules for free, through March 18th, on the www.asp.net/mvc website here: The 6 videos in this course are a total of 3 hours and 17 minutes long, and provide a nice overview of the new features introduced with ASP.NET MVC 3 including: Razor, Unobtrusive JavaScript, Richer Validation, ViewBag, Output Caching, Global Action Filters, NuGet, Dependency Injection, and much more.  Scott Allen is the presenter, and the format, video player, and cadence of the course is really excellent. It provides a great way to quickly come up to speed with all of the new features introduced with the new ASP.NET MVC 3 release. Introductory ASP.NET MVC 3 course also coming soon The above course provides a good way for people already familiar with ASP.NET MVC to quickly learn the new features in the V3 release. Pluralsight is also working on a new introductory ASP.NET MVC 3 course series designed for developers who are brand new to ASP.NET MVC, and who want an end to end training curriculum on how to come up to speed with it.  It will cover all of the basics of ASP.NET MVC (including the new Razor view engine), how to use EF code first for data access, using JavaScript/AJAX with MVC, security scenarios with MVC, unit testing applications, deploying applications, and more. I’m excited to pre-announce that we’ll also make this new introductory series free on the www.asp.net/mvc web-site for anyone to watch. I’ll do another blog post linking to it once it is live and available. Hope this helps, Scott

All of the live presentations were recorded, and videos of them will be posted shortly so that everyone can watch them (for free).  I’ll do a blog post with links to them once they are available. Special Pluralsight Training Available for Next 48 Hours In my MVCConf keynote this morning, I also mentioned a special offer that Pluralsight (a great .NET training partner) is offering – which is the opportunity to watch their excellent ASP.NET MVC 3 Fundamentals course free of charge for the next 48 hours.  This training is 3 hours and 17 minutes long and covers the new features introduced with ASP.NET MVC 3 including: Razor, Unobtrusive JavaScript, Richer Validation, ViewBag, Output Caching, Global Action Filters, NuGet, Dependency Injection, and much more. Scott Allen is the presenter, and the format, video player, and cadence of the course is really great.  It provides an excellent way to quickly come up to speed with all of the new features introduced with the new ASP.NET MVC 3 release.

Other Beginning ASP.NET MVC Tutorials We will be publishing a bunch of new ASP.NET MVC 3 content, training and samples on the http://asp.net/mvc web-site in the weeks ahead.  We’ll include content that is tailored to developers brand-new to ASP.NET MVC, as well as content for advanced ASP.NET MVC developers looking to get the most out of it. Below are two tutorials available today that provide nice introductory step-by-step ASP.NET MVC 3 tutorials: Build your First ASP.NET MVC 3 Application ASP.NET MVC Music Store Tutorial I recommend reviewing both of the above tutorials if you are looking to get started with ASP.NET MVC 3 and want to learn the core concepts and features behind it. Hope this helps, Scott
