• Postfix/dovecot remove LDAP user

  - by dove221

  I have to remove or blacklist an LDAP/dovecot user. The authentication is setup from active directory what I cannot manage so I thought there should be a way at least to disable this specific user on the mailserver locally. # Virtual Accoutns - LDAP - MS AD virtual_mailbox_maps = ldap:/etc/postfix/ldap_mailbox_maps.cf virtual_alias_maps = ldap:/etc/postfix/ldap_alias_maps_redirect_true.cf ldap:/etc/postfix/ldap_alias_maps_redirect_false.cf ldap:/etc/postfix/ldap_mailbox _groups.cf virtual_mailbox_domains = domain.com virtual_uid_maps = static:1000 virtual_gid_maps = static:1000 virtual_transport = dovecot dovecot_destination_recipient_limit = 1 Anybody knows how to do it? I followed this guide for disabling 1 user through postfixes access file: http://www.cyberciti.biz/faq/howto-blacklist-reject-sender-email-address/ Unfortunately it doesn't work. It's like the settings stored in LDAP are overruling the access rule. Instead of postfix rejecting the mail it keeps accepting it. Thanks!

• Is it possible to call BlazeDS from Java?

  - by Stephane Grenier

  Basically I'm trying to proxy some webservices locally (for reasons I won't go into now) and then have a Java application call it. I'm looking at BlazeDS since it seems to do just this, mostly to avoid the crossDomain.xml file required by Flex to call webservices. However I can't seem to find any reference on how to connect through a Java client (probably using Axis2). Any suggestions, and especially tutorials, would be greatly appreciated.

• How to tell httpd to preserve the proxied error message?

  - by ZNK - M

  I have an httpd server proxying the requests to 2 different tomcat servers. One of my server handles the authentication and returns a specific http error code 521 when the user already have a running session. My issue is httpd automatically maps this 521 error code to a 500 (internal server error) and then my client can not handle it properly. I have tried to disable ProxyErrorOverride, to remove the /error/HTTP_INTERNAL_SERVER_ERROR.html.var but it does not changes anything. How can I ask httpd to not change anything to the proxied message? <IfModule proxy_module> ProxyPass /context1 http://127.0.0.1:8001/context1 ProxyPass /context2 http://127.0.0.1:8002/context2 ProxyPreserveHost Off ProxyErrorOverride Off </IfModule> Thanks in advance httpd 2.2.22 (Win32) mod_ssl tomcat 7.25 windows 7 64-bits

• connect to a headless virtualbox instance in Linux?

  - by 130490868091234

  I've started a headless virtualbox instance with this command: VBoxManage startvm "Ensembl67VirtualMachine" --type headless Waiting for VM "Ensembl67VirtualMachine" to power on... VM "Ensembl67VirtualMachine" has been successfully started. It is set up with Remote Desktop Server Port:5555 with Authentication Method: Null and Extended Features: Allow Multiple Connections and it's now running, but I don't know how to connect to it from the same laptop where it's running. I would like to be able to have it running on a terminal. I tried this but nothing happens: rdesktop localhost:5555 ERROR: localhost: unable to connect rdesktop 192.168.1.1:5555 Any ideas?

• Apache https configurations

  - by sissonb

  I am trying to setup my domain name with a self signed cert. I created the cert and placed the server.key and server.crt files into C:/apache/config/ Then I updated my httpd.confg host to include the following, <VirtualHost 192.168.5.250:443> DocumentRoot C:/www ServerName mydomain.com:443 ServerAlias www.mydomain.com:443 SSLEngine on SSLCertificateFile C:/apache/conf/server.crt SSLCertificateKeyFile C:/apache/conf/server.key SSLVerifyClient none SSLProxyEngine off SetEnvIf User-Agent ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 CustomLog logs/ssl_request_log \ "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" </VirtualHost> Now when I go to https://mydomain.com I get the following error. SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. Can anyone see what I'm doing wrong? Thanks!

• avoiding the tedium of optional parameters

  - by Kyle

  If I have a constructor with say 2 required parameters and 4 optional parameters, how can I avoid writing 16 constructors or even the 10 or so constructors I'd have to write if I used default parameters (which I don't like because it's poor self-documentation)? Are there any idioms or methods using templates I can use to make it less tedious? (And easier to maintain?)

• apache, shibboleth, load balancing aliase, ssl

  - by Nikolaidis Fotis

  Good morning folks Could you give me a bit of help with the following problem ? I have a dns load balancing mechanism and an alias (hostAlias) which may point to host01, or host02 I want to configure apache and shibboleth to work with that alias. What happens is ... User types : https://hostAlias (it points to host01) apache host01 : redirect to shibboleth shibboleth host01 : redirect to **https://hostAlias.cern.ch/Shibboleth.sso/ADFS** Now, there are two cases. Either this time hostAlias will point again to host01 , or it will point to host02. If it points to host02, host01 will not get the anwser and the authentication fails. Also, about ssl certificates, I guess that each host will need its own certificate. right ? Should I need a certificate with DNS aliases ? Thanks in advance !

• How should I troubleshoot a problematic wireless connection on Linux?

  - by Gearoid Murphy

  I recently purchased a netgear 150 usb wireless dongle for use with my 11.10 Xubuntu amd64 system. Using the network-manager interface, I can see local wireless networks and enter the authentication details for my local wireless lan. Unfortunately, the connection does not seem to work, I keep getting notifications that my wireless has disconnected (but none indicating that I've connected). When I examine syslog, it seems to indicate that I've successfully associated with the wireless switch and that dhcp has successfully acquired an ip address but the log shows that the dhcp process keeps sending requests, eventually dropping the connection. 'ifconfig wlan0' never shows the dhcp address logged in syslog. I suspect that the problem lies with the usb dongle, my configuration or the wireless switch but I am not certain how to isolate the problem, can anyone provide some insight on how I should go about homing in on the cause of this problem or verifying the functionality of the individual components, thanks.

• What ports to open for mail server?

  - by radman

  Hi, I have just finished setting up a Postfix mail server on a linux (ubuntu) platform. I have it sending and receiving email and it is not an open relay. It also supports secure smtp and imap. Now this is a pretty beginner question but should I be leaving port 25 open? (since secure smtp is preferred). if so then why? Also what about port 587? Also should I require any authentication on either of these ports? Please excuse my ignorance in this area :P

• Ethernet 802.1x client -> WiFi AP on a Raspberry Pi?

  - by Martin Janiczek

  I have an Ethernet connection that requires 802.1x authentication (TTLS, MSCHAPv2, name+password). My goal is to connect that to something that would then act as an WiFi AP, so I can use the connection on more devices (iPhone, notebook, etc.) Would it be possible/good idea to use Raspberry Pi for this purpose? Or are there better-suited devices to do this? EDIT: found some alternatives but because of low rep can't post more than two links... OpenWRT + wpa_supplicant guide Carambola - works with OpenWRT (but probably not standalone?) Hornet-UB - works with OpenWRT Asus RT-N10+ + OpenWRT how-to EDIT 2: probably going to try TP-LINK TL-WR740N. It's a classic router, but can be flashed with OpenWRT, and the price beats everything else I've seen.

• creating a JQuery function

  - by Russell Parrott

  Sorry to bother you guys & girls again on Christmas eve, but I need help creating a reusable JQuery function. I have "badly crafted" this set of code that all works. But I would really like to put it as a function so I don't have to keep repeating everything for each form. I am not too sure about how all the if statements can be combined etc. that is why I wrote it as it is. Any help much appreciated - Oh I suppose it could also be some kind of plugin but that might be the next step if I can understand how the function works. $(':input:visible').live('blur',function(){ if($(this).attr('required')) { if($(this).val() == '' ) { $(this).css({'background-color':'#FFEEEE' }); $(this).parent('form').children('input[type=submit]').hide(); $(this).next('.errormsg').html('OOPs ... '+$(this).prev('label').html()+' is required'); $(this).focus(); $(this).attr('placeholder').hide(); } else { $(this).css({'background-color':'#FFF' , 'border-color':'#999999'}); $(this).next('.errormsg').empty(); $(this).parent('form').children('input[type=submit]').show(); } } return false; }); $(':input[max]').live('blur',function(){ if($(this).attr('max') < parseInt($(this).val()) ){ $(this).next('.errormsg').html( 'OOPs ... the maximum value is '+$(this).attr('max') ); $(this).parent('form').children('input[type=submit]').hide(); $(this).focus(); } else {} return false; }); $(':input[min]').live('blur',function(){ if($(this).attr('min') > parseInt($(this).val()) ){ $(this).next('.errormsg').html( 'OOPs ... the minimum value is '+$(this).attr('min') ); $(this).parent('form').children('input[type=submit]').hide(); $(this).focus(); } else {} return false; }); $(':input[maxlength]').live('keyup',function(){ if($(this).val()==''){ } else { $(this).next('.errormsg').html( $(this).attr('maxlength')- $(this).val().length +' chars remaining'); } return false; }); As said, help much appreciated with one small (I hope) thing, how can I break out of any function IF there are no error messages to actually submit the form?

• How to access remotly to a mysql server?

• How can I make this Perl regex work?

  - by Geo

  I have this line ( it's a single line, SO makes it seem like 2 ): /Od /D "WIN32" /D "_DEBUG" /FD /EHa /MDd /Fo"Debug" /Fd"Debug\vc80.pdb" /W3 /c /Zi /clr /TP .\main.cpp" And I want to extract the .\main.cpp. I thought the following would do the trick: if($string =~ /.*\s+(.*)$/i) { print "matched ",$1,"\n"; } because this same regex works in Ruby, and extracts the string I required. How can I get it working?

• Apache - Same username in several .htpasswd files

  - by greydet

  In a virtual host, I setup two different <Location> blocks for which the access is restricted by two basic authentication htpasswd files. One htpasswd contains different usernames + a common user name. The other htpasswd file only contains the common user name. My problem is that once users connect a location with the common user name, they have immediate access to the other location without being asker for a different user name. Is there a way to restrict the username access only to the corresponding htpasswd file? Is there a way for users to ask to be re-prompted for another username/password?

• Forcing the from address when postfix relays over smtp

  - by John Whitlock

  I'm trying to get email reports from our AWS EC2 instances. We're using Exchange Online (part of Microsoft Online Services). I've setup a user account specifically for SMTP relaying, and I've setup Postfix to meet all the requirements to relay messages through this server. However, Exchange Online's SMTP server will reject messages unless the From address exactly matches the authentication address (the error message is 550 5.7.1 Client does not have permissions to send as this sender). With careful configuration, I can setup my services to send as this user. But I'm not a huge fan of being careful - I'd rather have postfix force the issue. Is there a way to do this?

• Putting a Windows DC, Exchange in a DMZ

  - by blsub6

  I have one guy at my company telling me that I should put FF:TMG in between my main Internet-facing firewall (Cisco 5510) and put my Exchange server and DC on the internal network. I have another guy telling me that I should put the Exchange server and DC in a DMZ I don't particularly like the idea of having my mailboxes and DC's usernames/passwords in a DMZ and I think that Windows authentication would require me opening up so many ports between my DMZ and my internal network that it would be a moot point to have it out there anyways. What are some thoughts? How do you have it set up?

• Microsoft CA certificate templates expires sooner than expected

  - by Tim Brigham

  The certificates my Microsoft CA is generating do not match the time period indicated in the template used. How can I resolve this? I recently created a new certificate template for use on my Linux boxes on my Microsoft CA (2008 R2 Enterprise). This template is approved for server and client authentication purposes with a validity period of 10 years - the expected lifetime of our Linux boxes - and the subject name supplied in the request. I have checked both the intermediate and offline CA - both have more than 10 years of life listed. Is there some kind of hard limit I'm hitting here?

• My laptop was stolen. What do I need to do?

  - by chris

  My laptop was recently stolen. It was a corporate system running XP, which means it was part of a domain - I'm assuming that makes it impossible for someone to log into it, although I know there are ways to reset the local admin account. Is there any way to tell if someone boots it up? I was logged into gmail, using two factor authentication. I will change my password, but is there any chance of tracking any attempted accesses? Other than changing passwords on all my web accounts, is there anything else I need to do?

• Impersonation on IIS 7.0 passes the machine credentials for Crystal Reports

  - by pknox

  On a 32-bit Windows 2008 server running the Donor2 Application in the Classic .NET Managed Pipeline mode, configured for Windows Integrated Authentication and Impersonation, all of the .NET pages are passing the authenticated user’s credentials [DomainName\UserName]. This is the correct, expected behavior. The Crystal Reports pages, instead of passing the authenticated user’s credentials, are passing the IIS Server’s credentials [DomainName\MachineName$]. One of the very frustrating aspects of this situation is that I have another server which, as far as I can tell, is configured identically. That server, when loading Crystal Reports, is passing the authenticated user’s credentials [DomainName\UserName] as expected. I have obviously missed something, but I have no idea what it could be.

• Passing Auth to API calls with Web Service References

  - by coffeeaddict

  I am new to web services. The last time I dealt with SOAP was when I created a bunch of wrapper classes that sent requests and received responses back per some response objects/classes I had created. So I had an object to send certain API requests and likewise a set of objects to hold the response back as an object so I could utilize that 3rd party API. Then someone came to me and said why not just use the wsdl and a web service. Ok, so today I went and created a "Service Reference". I see that this is what's called a "Proxy Class". You just instantiate an instance of this and then walla you have access to all the methods from the wsdl. But this leaves me with auth questions. Back when I created my own classes manually, I had a class which exposed properties that I would set then access for things like signature, username, password that got sent along with the Http request that were required by whatever 3rd party API I was using to make API calls. But then with using a Service Reference, how then would I pass this information just like I had done in my custom classes? For instance I'm going to be working with the PayPal API. It requires you to send a signature and a few other pieces of information like username and password. // Determins if API call needs to use a session based URI string requestURI = UseAuthURI == true ? _requestURIAuthBased + aSessionID : _requestURI; byte[] data = XmlUtil.DocumentToBytes(doc); // Create the atual Request instance HttpWebRequest request = CreateWebRequest(requestURI, data.Length); So how do I pass username, password, signature, etc. when using web service references for each method call? Is it as simple as specifying it as a param to the method or do you use the .Credentials and .URL methods of your proxy class object? It seems to me Credentials means windows credentials but I could be wrong. Is it limited to that or can you use that to specify those required header values that PayPal expects with each method call/API request?
