• Spam mail through SMTP and user spoofing

  - by Josten Moore

  I have noticed that it's possible to telnet into a mailserver that I own and send spoofed messages to other clients. This only works for the domain that the mail server is regarding; I cannot do it for other domains. For example; lets say that I own example.com. If I telnet example.com 25 I can successfully send a message to another user without authentication: HELO local MAIL FROM: [email protected] RCPT TO: [email protected] DATA SUBJECT: Whatever this is spam Spam spam spam . I consider this a big problem; how do I secure this?

• How do I link gtk library more easily with cmake in windows?

  - by Runner

  I'm now doing it in a very ugly way by manually including all the required path(the gtk bundle is at D:/Tools/gtk+-bundle_2.20.0-20100406_win32): include_directories(D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/gtk-2.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/glib-2.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib/glib-2.0/include D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/cairo D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/pango-1.0 D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib/gtk-2.0/include D:/Tools/gtk+-bundle_2.20.0-20100406_win32/include/atk-1.0) link_directories(D:/Tools/gtk+-bundle_2.20.0-20100406_win32/lib) target_link_libraries(MyProgram gtk-win32-2.0.lib)

• Client-side certificates

  - by walshms

  My company purchased a wildcard certificate from a vendor. This certificate was successfully configured with Apache 2.2 to secure a subdomain. Everything on the SSL side works. Now I'm required to generate x509 client-side certificates to issue for this subdomain. I'm following along this page: (http://www.vanemery.com/Linux/Apache/apache-SSL.html), starting with "Creating Client Certificates for Authentication". I've generated the p12 files and successfully imported them into Firefox. When I browse to the site now, I get an error in FireFox that says "The connection to the server was reset while the page was loading." I think my problem is coming from not signing the client-side correctly. When I sign the client-side certificate, I'm using the PEM file (RapidSSL_CA_bundle.pem) from RapidSSL (who we bought the certificate from) for the -CA argument. For the -CAkey argument, I'm using the private key of the server. Is this correct?

• Is it possible to develop a remote desktop server application?

  I just want to know whether it is possible to develop an Android application that will allow remotely controlling an Android phone in the same way that remote desktop, or team viewer allows control over desktop operating systems. Is it possible on an unrooted phone? The basic functionlit required to acompolish this is would be the ability to capture the frame buffer and programmatically invoke touch on the device. Any feedback on this matter would be highly appreciated.

• Any Alternatives to NCommon?

  - by Innogetics

  I like the way NCommon saves me from dealing with all the plumbing required to do DDD with NHibernate. I like it so much that it I am seriously considering it to be part of my default architecture in new projects. I'd like to ask if there are other DDD alternatives (aside from coding from scratch) to what NCommon does. Thanks.

• ServeletException, Property <variable name> not found

  - by k9yosh

  What i'm trying to do is add a new variable to this previously created Managed Bean Hello.java and use it in my xhtml file binding to a text field. But it seems that it is not being found when i run it on the server. So it throws a "ServeletException" and says that the "property 'lname'(my variable) is not found". How do i solve this and why is this happening? This is my managed bean, package stack.tute.malinda.model; import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped; @ManagedBean @RequestScoped public class Hello { private String fname; private String message; private String lname; //trying to add this new variable and use it in my xhtml file in a text field. public String getLname() { return lname; } public void setLname(String lname) { this.lname = lname; } public String getName() { return fname; } public String createMessage() { message="Hello " + fname + ""+ lname +"!"; return null; } public void setName(String fname) { this.fname=fname; } public String getMessage() { return message; } } This is my xhtml code, <h:body> <fieldset style="padding: 1em; float:left; margin-right:0.5em; padding-top:0.2em; text-align:left; border:1px solid green; font-weight:bold;"> <legend>Personal Details</legend> <h:form> <h:outputLabel for="name" value="First Name :" required="true"/> <h:inputText id="name" value="#{hello.name}"/> <br/> //Trying to access that variable here. <h:outputLabel for="name1" value="Last Name :" required="true"/> <h:inputText id="name1" value="#{hello.lname}"/> <h:message for="name"/> <br/> <h:commandButton value="Say hello" action="#{hello.createMessage}"> <f:ajax execute="@form" render="@form"/> </h:commandButton> <br/> <h:outputText value="#{hello.message}"/> </h:form> </fieldset>

• jquery radio button group problem

  - by user198937

  Hi, I have a radio group which is validated for required. It works fine except when in certain cases I need to disabled first radio button leaving user to select one from remaining. Even in this case radios are validated but error message is not displayed. I believe its due to error message's association with first radio. Disabling other radio except first works fine too. Is there way around?

• Apache Request IP Based Security

  - by connec

  I run an Apache server on my home system that I've made available over the internet as I'm not always at my home system. Naturally I don't want all my home server files public, so until now I've simply had: Order allow, deny Deny from all Allow from 127.0.0.1 in my core configuration and just Allow from all in the htaccess of any directories I wanted publicly viewable. However I've decided a better system would be to centralise all the access control and just require authentication (HTTP basic) for requests not to 127.0.0.1/localhost. Is this achievable with Apache/modules? If so how would I go about it? Cheers.

• WLC 4400. Get IP

  - by Edward Connelly

  I have three SSID. one is a guest network and I'm having problems with lease times. Its set for web authentication so it passes IPs out even if someone doesn't try and authenticate. Is there a way to get that IP back and not hand another to that mac for a period of time? Poor planning and we didn't allocate enough address space, and we are sandwitched. We could go with another address, but we would have to reconfig lots. since its guest its vlan'd with no access to anthing but the firewalls. would have to change ACLs and routes and interfaces. if it isn't possible we will just have to go that route, just thought there might be an easier solution. session timeout is enabled with 1 hr lease time is set to 4 hrs. no helper DHCP and internal DHCP is set with the space split across three WLCs (60 waps split across those as well).

• Does armcc optimizes non-volatile variables with -O0 ?

  - by Dor

  int* Register = 0x00FF0000; // Address of micro-seconds timer while(*Register != 0); Should I declare *Register as volatile while using armcc compiler and -O0 optimization ? In other words: Does -O0 optimization requires qualifying that sort of variables as volatile ? (which is probably required in -O2 optimization)

• Multiple connections to the same Wireless Network in Windows 7

  - by Jamek

  Hello, my university just limited bandwidth to 512 kbps (that's 64 kB/s!) for each connection. I was thinking to make multiple connection to the same wireless network (called "internet"), is this possible under Windows 7? I know it's possible to connect to more than one WLAN through the "hostednetwork" concept in netsh: netsh wlan set hostednetwork mode=allow ssid=xxxxx netsh wlan start hostednetwork However this method doesn't seem to work, I don't know if it's due to the authentication method (through certificates while hostednetwork seems to support just a "passphrase") or because I'm already connected to that network with the same MAC. Can you think to some tool able to do this?

• iPad revocable vpn access

  - by carpat

  I'm a programmer at my organization, but somehow got drafted into looking into some server stuff so forgive me of my ignorance: They want to give our sales people secure access to our internal sites using their iPads. This must be secure (obviously) but also revocable from the company's side (if someone quits they can no longer access our network). I see from http://support.apple.com/kb/HT1288 that the iPad supports "RSA SecurID", "CRYPTOCard", and "Kerberos" authentication methods. Will one of these do what we need? Are there any major differences between them?

  I have an Apache server in a DMZ, reachaable on the LAN from 192.168.1.1, public 123.456.789.123. I'm trying to get it to require authentication if the inbound hits are coming from the public side.

• Accessing custom user profile fields in CCK

  - by Nick Lowman

  I'm probably going about this the wrong way but... I’ve added a field to the User Profile called profile_real_name which is required by the user. Is there a way to access the details in CCK? For example in CCK when creating a new field I can access the user’s username with the ‘User reference’ Field type and setting the ‘Widget type’ to ‘Autocomplete text field’. Can I do the same with my real name field? Many thanks

• Samba domain trust errors on a specific interface

  - by John K

  We have a windows domain that also has RHEL member servers in it. All the servers have a primary network connection to the LAN, but some servers also have private dedicated links to one of our RHEL servers, which serves as a head to our SAN storage. This particular server is running Samba 3.5.15, and is running in domain authentication mode. Users can access shares on this server without a problem over the LAN connection from our Windows servers, but if a user tries to access the shares over a private link (i.e. a 192.168.1.2 address to the RHEL server) users get an error "The trust relationship between this workstation and the primary domain failed."
