  • How to test if SYN and FIN are both dropped at the same time in hping3?

    - by snow
    One of the rules to prevent unexpected attack is to prevent SYN & FIN being used together. SYN and FIN are both set $IPT -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP How do I use hping to test if this iptable rule works? hping3 192.168.7.0 --keep -S -F??? Is this complete? When just type iptables -L, it shows: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere DROP tcp -- anywhere anywhere tcp flags:FIN,SYN/FIN,SYN WHY do I need to put the "SYN,FIN" twice before drop? Is it because one for source and one for destination?

  • Best practices for mass email platform

    - by Niro
    I am in the process of setting up mass email service. My question is: what are the best practices to achieve maximum deliver-ability. More precisely - what should I do/know to prevent spam filters from blocking the emails (the emails are not spam). for example- how can I tell if my IP address is blacklisted somewhere and how can I prevent it from becoming blacklisted. Is amazon web services a suitable platform due to dynamic IP addresses, what are the restrictions on the from address, can it be different from the mail server domain.... you get it....

  • Can I configure a DNS cache not to forward AAAA queries?

    - by itsadok
    I'm setting up an internal DNS cache because my firewall is having trouble handling all the sessions created by DNS requests. I tried using bind9, dnsmasq and DJB dnscache, they all help reduce the number of requests leaving my network, but there are still a lot of request being made. Looking at the log files, and tcpdump and dnstop outputs, it seems that requests that return SERVFAIL do not get cached at all. And a lot of those failed requests are AAAA requests, which is a shame, because I do not have ipv6 enabled on any server. I've looked at several ways to help the situation, and I think if I could somehow prevent AAAA record requests from being forwarded by the DNS cache, it would reduce the number of requests significantly. The closest thing I found was the filter-aaaa-on-v4 option in BIND9. However, this only removes the record from the server response, and does not prevent it from forwarding it. Any help would be appreciated.

  • Python, dictionaries, and chi-square contingency table

    - by rohanbk
    I have a file which contains several lines in the following format (word, time that the word occurred in, and frequency of documents containing the given word within the given instance in time): #inputfile <word, time, frequency> apple, 1, 3 banana, 1, 2 apple, 2, 1 banana, 2, 4 orange, 3, 1 I have Python class below that I used to create 2-D dictionaries to store the above file using as the key, and frequency as the value: class Ddict(dict): ''' 2D dictionary class ''' def __init__(self, default=None): self.default = default def __getitem__(self, key): if not self.has_key(key): self[key] = self.default() return dict.__getitem__(self, key) wordtime=Ddict(dict) # Store each inputfile entry with a <word,time> key timeword=Ddict(dict) # Store each inputfile entry with a <time,word> key # Loop over every line of the inputfile for line in open('inputfile'): word,time,count=line.split(',') # If <word,time> already a key, increment count try: wordtime[word][time]+=count # Otherwise, create the key except KeyError: wordtime[word][time]=count # If <time,word> already a key, increment count try: timeword[time][word]+=count # Otherwise, create the key except KeyError: timeword[time][word]=count The question that I have pertains to calculating certain things while iterating over the entries in this 2D dictionary. For each word 'w' at each time 't', calculate: The number of documents with word 'w' within time 't'. (a) The number of documents without word 'w' within time 't'. (b) The number of documents with word 'w' outside time 't'. (c) The number of documents without word 'w' outside time 't'. (d) Each of the items above represents one of the cells of a chi-square contingency table for each word and time. Can all of these be calculated within a single loop or do they need to be done one at a time? Ideally, I would like the output to be what's below, where a,b,c,d are all the items calculated above: print "%s, %s, %s, %s" %(a,b,c,d)

  • Can I copy/clone a function in JavaScript?

    - by Craig Stuntz
    I'm using jQuery with the validators plugin. I would like to replace the "required" validator with one of my own. This is easy: jQuery.validator.addMethod("required", function(value, element, param) { return myRequired(value, element, param); }, jQuery.validator.messages.required); So far, so good. This works just fine. But what I really want to do is call my function in some cases, and the default validator for the rest. Unfortunately, this turns out to be recursive: jQuery.validator.addMethod("required", function(value, element, param) { // handle comboboxes with empty guids if (someTest(element)) { return myRequired(value, element, param); } return jQuery.validator.methods.required(value, element, param); }, jQuery.validator.messages.required); I looked at the source code for the validators, and the default implementation of "required" is defined as an anonymous method at jQuery.validator.messages.required. So there is no other (non-anonymous) reference to the function that I can use. Storing a reference to the function externally before calling addMethod and calling the default validator via that reference makes no difference. What I really need to do is to be able to copy the default required validator function by value instead of by reference. But after quite a bit of searching, I can't figure out how to do that. Is it possible? If it's impossible, then I can copy the source for the original function. But that creates a maintenance problem, and I would rather not do that unless there is no "better way."

  • How to make Shared Keys .ssh/authorized_keys and sudo work together?

    - by farinspace
    I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like: $ sudo cd /root it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set) Also, ive disabled the users password using $ passwd -l user What am I missing? Somewhere my initial remarks are being misunderstood ... I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file. Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time). For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password. But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled. Edit: Ok I think I've got it (the solution): 1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this 2) I've adjusted the sudoers list visudo and added root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL 3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user) The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user. NOTE The above works but is considered poor security. Any script that is able to access code as the "dimas" or "sherry" users will be able to execute sudo to gain root access. A bug in ssh that allows remote users to log in despite the settings, a remote code execution in something like firefox, or any other flaw that allows unwanted code to run as the user will now be able to run as root. Sudo should always require a password or you may as well log in as root instead of some other user.

  • chrome frame causes postback to wrong url and a Server Error in '/' Application error

    - by Johnny S

  • Original sender is not correctly identified when spam is forwarded

    - by Stephan Burlot
    I have a forwarding rule with Postfix that forwards all messages to my main email address. When a spam message is sent to one of my emails, it is forwarded but the sender is shown as being the forwarding domain, not the spammer's domain. Real example: mywebsite.com is hosted on Linode. [email protected] sends an email to [email protected] the mail is forwarded to [email protected] my email hosting (anotherwebsite.com) sees it's spam and sends a message to [email protected] and Linode reports a TOS violation. I have modified my postfix settings so I now use RBL, but if a message goes through, it may happen again. How can I prevent this to happen again? Is there some settings to change on Postfix so the original sender is correctly identified? Thanks Stephan EDIT: The steps I did to prevent this to happen again are: Add RBL checking to Postfix Add postgrey to Postfix And finally fix the MX record which was incorrect. I checked with a test email on Spamcop.net and the original sender is correctly identified.

  • JSON Serialization of a Django inherited model

    - by Simon Morris
    Hello, I have the following Django models class ConfigurationItem(models.Model): path = models.CharField('Path', max_length=1024) name = models.CharField('Name', max_length=1024, blank=True) description = models.CharField('Description', max_length=1024, blank=True) active = models.BooleanField('Active', default=True) is_leaf = models.BooleanField('Is a Leaf item', default=True) class Location(ConfigurationItem): address = models.CharField(max_length=1024, blank=True) phoneNumber = models.CharField(max_length=255, blank=True) url = models.URLField(blank=True) read_acl = models.ManyToManyField(Group, default=None) write_acl = models.ManyToManyField(Group, default=None) alert_group= models.EmailField(blank=True) The full model file is here if it helps. You can see that Company is a child class of ConfigurationItem. I'm trying to use JSON serialization using either the django.core.serializers.serializer or the WadofStuff serializer. Both serializers give me the same problem... >>> from cmdb.models import * >>> from django.core import serializers >>> serializers.serialize('json', [ ConfigurationItem.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.configurationitem", "fields": {"is_leaf": true, "extension_attribute_10": "", "name": "", "date_modified": "2010-05-19 14:42:53", "extension_attribute_11": false, "extension_attribute_5": "", "extension_attribute_2": "", "extension_attribute_3": "", "extension_attribute_1": "", "extension_attribute_6": "", "extension_attribute_7": "", "extension_attribute_4": "", "date_created": "2010-05-19 14:42:53", "active": true, "path": "/Locations/London", "extension_attribute_8": "", "extension_attribute_9": "", "description": ""}}]' >>> serializers.serialize('json', [ Location.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.location", "fields": {"write_acl": [], "url": "", "phoneNumber": "", "address": "", "read_acl": [], "alert_group": ""}}]' >>> The problem is that serializing the Company model only gives me the fields directly associated with that model, not the fields from it's parent object. Is there a way of altering this behaviour or should I be looking at building a dictionary of objects and using simplejson to format the output? Thanks in advance ~sm

  • Disable chaching in JPA (eclipselink)

    - by James
    Hi, I want to use JPA (eclipselink) to get data from my database. The database is changed by a number of other sources and I therefore want to go back to the database for every find I execute. I have read a number of posts on disabling the cache but this does not seem to be working. Any ideas? I am trying to execute the following code: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one==two); one==two is true while I want it to be false. I have tried adding each/all the following to my persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.cache.size.default" value="0"/> <property name="eclipselink.cache.type.default" value="None"/> I have also tried adding the @Cache annotation to the Entity itself: @Cache( type=CacheType.NONE, // Cache nothing expiry=0, alwaysRefresh=true ) Am I misunderstanding something? Thank you, James

  • In asp.Net, writing code in the control tag generates compile error

    - by Nour Sabouny
    Hi this is really strange !! But look at the following asp code: <div runat="server" id="MainDiv"> <%foreach (string str in new string[]{"First#", "Second#"}) { %> <div id="<%=str.Replace("#","div") %>"> </div> <%} %> </div> now if you put this code inside any web page (and don't worry about the moral of this code, I made it just to show the idea) you'll get this error : Compiler Error Message: CS1518: Expected class, delegate, enum, interface, or struct Of course the error has nothing to do with the real problem, I searched for the code that was generated by asp.net and figured out the following : private void @__RenderMainDiv(System.Web.UI.HtmlTextWriter @__w, System.Web.UI.Control parameterContainer) { @__w.Write("\r\n "); #line 20 "blabla\blabla\Default.aspx" foreach (string str in new string[] { "First#", "Second#" }) { #line default #line hidden @__w.Write("\r\n <div id=\""); #line 22 "blabla\blabla\Default.aspx" @__w.Write(str.Replace("#", "div")); #line default #line hidden @__w.Write("\">\r\n "); } This is the code that was generated from the asp page and this is the method that is meant to render our div (MainDiv), I found out that there is a missing bracket "}" that closes the method or the (for loop). now the problem has three parts: 1- first you should have a server control (in our situation is the MainDiv) and I'm not sure if it is only the div tag. 2- HTML control inside the server control and a code inside it using the double quotation mark ( for example <div id="<%=str instead of <div id='<%=str. 3-Any keyword which has block brackets e.g.:for{},while{},using{}...etc. now removing any part, will solve the problem !!! how is this happening ?? any ideas ? BTW: please help me to make the question more obvious, because I couldn't find the best words to describe the problem.

  • db:migrate creates sequences but doesn't alter table?

    - by RewbieNewbie
    Hello, I have a migration that creates a postres sequence for auto incrementing a primary identifier, and then executes a statement for altering the column and specifying the default value: execute 'CREATE SEQUENCE "ServiceAvailability_ID_seq";' execute <<-SQL ALTER TABLE "ServiceAvailability" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceAvailability_ID_seq'); SQL If I run db:migrate everything seems to work, in that no errors are returned, however, if I run the rails application I get: Mnull value in column "ID" violates not-null constraint I have discovered by executing the sql statement in the migration manually, that this error is because the alter statement isn't working, or isn't being executed. If I manually execute the following statement: CREATE SEQUENCE "ServiceAvailability_ID_seq; I get: error : ERROR: relation "serviceavailability_id_seq" already exists Which means the migration successfully created the sequence! However, if I manually run: ALTER TABLE "ServiceProvider" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceProvider_ID_seq'); SQL It runs successfully and creates the default NEXTVAL. So the question is, why is the migration file creating the sequence with the first execute statement, but not altering the table in the second execute? (Remembering, no errors are output on running db:migrate) Thank you and apologies for tl:dr

  • Sendmail - preventing aliased users from receiving multiple copies of the same email

    - by MikeQ
    Is there any way to prevent a user from receiving multiple copies of the same email if an email is sent to both an alias for the user as well as the user themselves? For example, suppose bob.smith is a included in the alias list for developers (@company.com) If I send the email to both the user and an alias for the user: To: [email protected], [email protected] ... is there any way to prevent user Bob from receiving the same email two times? EDIT: I've observed that if Bob is a member of two different alias groups, and I send an email just to those two groups (not the user directly), sendmail correctly expands the groups and removes the duplicate. The behavior I want to fix occurs when you send directly to the user AND a group they belong to.

  • Windows 7 resizes desktop when I switch of a monitor

    - by Stijn Sanders
    I have a workstation with two monitors and the desktop extended over them. I have a lot of applications open (generally maximized), and I have a personal preference which application is on which monitor (let's say editors on the right, data retrieval and display on the left). I have recently upgraded to a workstation with Windows 7 and when I power off a monitor (typically when going home at the end of the day), the desktop-expand-over-monitors disables and all applications are switched to the main monitor. (Also the taskbar I keep on the left resizes to about one icon's width.) This is highly annoying, since I now spend the first minutes of work each day switching the applications back that were on the monitor on the right. Is there a way to prevent this? (It says no here.) Is there software I could install that can prevent this?

  • How do I specify Open ID Realm in spring security ?

    - by Salvin Francis
    We are using Spring security in our application with support for username / password based authentication as well as Open id based authentication. The issue is that google gives a different open id for the return url specified and we have at least 2 different entry points in our application from where open id is configured into our system. Hence we decided to use open id realm. http://blog.stackoverflow.com/2009/0...ue-per-domain/ http://groups.google.com/group/googl...unts-api?pli=1 how is it possible to integrate realm into our spring configuration/code ? This is how we are doing it in traditional openid library code: AuthRequest authReq = consumerManager.authenticate(discovered, someReturnToUrl,"http://www.example.com"); This works and gives same open id for different urls from our site. our configuration: Code: ... <http auto-config="false"> <!-- <intercept-url> tags are here --> <remember-me user-service-ref="someRememberedService" key="some key" /> <form-login login-page="/Login.html" authentication-failure-url="/Login.html?error=true" always-use-default-target="false" default-target-url="/MainPage.html"/> <openid-login authentication-failure-url="/Login.html?error=true" always-use-default-target="true" default-target-url="/MainPage.html" user-service-ref="someOpenIdUserService"/> </http> ... <beans:bean id="someOpenIdUserService" class="com.something.MyOpenIDUserDetailsService"> </beans:bean> <beans:bean id="openIdAuthenticationProvider" class="com.something.MyOpenIDAuthenticationProvider"> <custom-authentication-provider /> <beans:property name="userDetailsService" ref="someOpenIdUserService"/> </beans:bean> ...

  • Mono doesn't write settings defaults

    - by Petar Minchev
    Hi guys! Here is my problem. If I use only one Windows Forms project and call only - Settings.Default.Save() when running it, Mono creates a user.config file with the default value for each setting. It is fine, so far so good. But now I add a class library project, which is referenced from the Windows Forms project and I move the settings from the Windows Forms project to the Class Library one. Now I do the same - Settings.Default.Save() and to my great surprise, Mono creates a user.config file with EMPTY values(NOT the default ones) for each setting?! What's the difference between having the settings in the Windows Forms Project or in the class library one? And by the way it is not a operating system issue. It is a Mono issue, because it doesn't work both under Windows and Linux. If I don't use Mono everything is fine, but I have to port my application to Linux, so I have to use Mono. I am really frustrated, it is blocking a project:( Thanks in advance for any suggestion you have. Regards, Petar

  • Reasonable Location to Install Web Service on Server

    - by Mr. Disappointment
    Firstly, I'm a software developer and not qualified as any kind of system or server expert so I'm looking for advice in order to help me prevent faults on our server. I've written a modular system to carry out certain tasks for us autonomously to prevent us from writing the same old code over and over again. This consists of a Windows Service (.NET), a Web Service (WCF), a shared Class Library, and a Database which will run on a Windows Server 2003. The problem comes, for me, in deployment. Specifically the web service - naturally the local service (and required shared library) are persisted (by default and convention) in the Program Files folder, but storing the web service here just seems absurd to me (even though we'd lock it down to appropriate use only). Should the files be stored some place else all together? Or split them up and store the web service elsewhere?

  • Pros/cons of reading connection string from physical file vs Application object (ASP.NET)?

    - by HaterTot
    my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production). It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings. I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often). I was considering storing the connection string in Application["ConnectionString"]. So the code would be public static string GetConnectionString { if (Application["ConnectionString"] == null) { XmlDocument doc = new XmlDocument(); doc.Load(HttpContext.Current.Request.PhysicalApplicationPath + "bin/ServerEnvironment.xml"); XmlElement xe = (XmlElement) xnl[0]; switch (xe.InnerText.ToString().ToLower()) { case "local": connString = Settings.Default.ConnectionStringLocal; break; case "development": connString = Settings.Default.ConnectionStringDevelopment; break; case "production": connString = Settings.Default.ConnectionStringProduction; break; default: throw new Exception("no connection string defined"); } Application["ConnectionString"] = connString; } return Application["ConnectionString"].ToString(); } I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons? Do you think I'd see a small performance gain by implementing the function above? THANKS
