• embedded tomcat 7 behind iis 7.5 proxy ssl problems

  - by user1058410

  I'm using embedded tomcat 7 behind a iis 7.5 proxy server, with requests being forwarded to tomcat with arr. Everything works fine unless iis is set to require ssl. Then things like links that are generated dynamically in .jsp files on tomcat don't work right. For example if a link is supposed to point to _https://somewhere.com:443 it will be wrote as _http://somewhere.com:8080 (8080 is the port tomcat is running on). The problem seems to come from when tomcat looks at itself to build out the url it sees correctly that it is running on _http://somewhere.com:8080, but i need it to think otherwise. Does anybody know how to accomplish this without using ssl between iis and tomcat? Sorry for the underscores in front of the imaginary urls.

• Safari, IIS and optional Client Certificates

  - by Philipp

  I've a ASP.Net Webapp running on IIS7.5. The Webserver is configured to accept Client Certifcates. Unfortunately Visitors with Safari Browser are unable to view the Page. Same Problem as described under the following link: http://www.mnxsolutions.com/apache/safari-providing-an-ssl-error-client-certificate-rejected%E2%80%9D-when-other-browsers-work.html Does anyone knows how to solve this?

• Is visiting HTTPS websites on a public hotspot secure?

  - by Calmarius

  It's often said that HTTPS SSL/TLS connections are encrypted and said to be secure because the communication between the server and me is encrypted (also provides server authentication) so if someone sniffs my packets, they will need zillions of years to decrypt if using brute force in theory. Let's assume I'm on a public wifi and there is a malicious user on the same wifi who sniffs every packet. Now let's assume I'm trying to access my gmail account using this wifi. My browser does a SSL/TLS handshake with the server and gets the keys to use for encryption and decryption. If that malicious user sniffed all my incoming and outgoing packets. Can he calculate the same keys and read my encrypted traffic too or even send encrypted messages to the server in my name?

• 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?

• How can write a mod_rewrite rule to determine if the domain is not the main domain then change https:// to http://

  - by Oudin

  I've set up a WordPress multi-site with a wildcard ssl for example.com to access the admin area securely. However I'm also using domain mapping to map other domains to other sites e.g. alldogs.com to alldogs.example.com. The problem is when I'm trying to access the front end of a site from and admin for a mapped domain e.g. alldogs.com by clicking "Visit Site" the Link goes to https://alldogs.com because of the forced ssl applied to the admin area. Which produces a certificate warning since the certificate is for example.com and not alldogs.com. How can write a mod_rewrite rule to determine if the url/link clicked on is not the main domain e.g. example.com then change the https:// to http:// so the site can be accessed via port 80 and not generate a certificate warning for that mapped domains

• "Countersigning" a CA with openssl

  - by Tom O'Connor

  I'm pretty used to creating the PKI used for x509 authentication for whatever reason, SSL Client Verification being the main reason for doing it. I've just started to dabble with OpenVPN (Which I suppose is doing the same things as Apache would do with the Certificate Authority (CA) certificate) We've got a whole bunch of subdomains, and applicances which currently all present their own self-signed certificates. We're tired of having to accept exceptions in Chrome, and we think it must look pretty rough for our clients having our address bar come up red. For that, I'm comfortable to buy a SSL Wildcard CN=*.mycompany.com. That's no problem. What I don't seem to be able to find out is: Can we have our Internal CA root signed as a child of our wildcard certificate, so that installing that cert into guest devices/browsers/whatever doesn't present anything about an untrusted root? Also, on a bit of a side point, why does the addition of a wildcard double the cost of certificate purchase?

• HTTPS subdomain does not load site under HTTP

  - by Mark Lawrence

  I recently installed an SSL certificate on a subdomain following the steps at cPanel. Lets just say the domain is example.com and the subdomain is sub.example.com. I updated the userdata file for the subdomain and changed the IP address to the IP I wanted to use I updated the example.com zone file and changed the IP for the A Name for the subdomain to the IP I wanted to use Using domain tools I checked that sub.example.com resolved to the new IP which it does. I then installed an SSL certificate on example.com and then on sub.example.com When I visit http://sub.example.com I get the default Apache account screen, and when I visit https://sub.example.com I get the cPanel 404 page. If however I enter https://sub.example.com/admin (the location of my admin section) the page loads and I can login. I thought that this might be a propagation issue however as the subdomain resolves to the IP and I can reach the admin page I suspect it is not a propagation issue and possibly an incorrect zone file. Any thoughts?

• All HTTPS, or is it OK to accept HTTP and redirect (secure vs. user friendly)

  - by tharrison

  Our site currently redirects requests sent to http://example.com to https://example.com -- everything beyond this is served over SSL. For now, the redirect is done with an Apache rewrite rule. Our site is dealing with money, however, so security is pretty important. Does allowing HTTP in this way pose any greater security risk than just not opening or listening on port 80? Ideally, it's a little more user-friendly to redirect. (I am aware that SSL is only one of a large set of security considerations, so please make the generous assumption that we have done at least a "very good" job of covering various security bases.)

• Authenticating SSL in Paros Proxy

  - by Chevi

  I need to inspect some traffic from my iPhone to debug an application, which is going and coming from an https address. Since I don't have a Mac at the moment, I tried with Paros proxy, which I had used before. It's working fine with http connections, but whenever I try to open a website with SSL encryption in Mobile Safari it says that the certificate is not trusted. I can "Continue" and it would work, but not on Applications. How can I set up a trusted certificate with Paros and the iPhone? Thanks in advance, Alex UPDATE: I'm going to try and create my own SSL certificate for testing with Windows' MakeCert UPDATE 2: For some reason I could get Windows SDK to install, so I haven't tried this yet...

• using main domain as a mail server

  - by zensys

  I have a mail server set up as mail.mydomain.com like most people do. Now I find out that if I want to secure both mail.mydomain.com and mydomain.com with ssl I need two SSl certificates (or one more versatile but more expensive certificate). Does it make sense to run my mail server under mydomain.com (it is the same physical machine anyway) to save certificate expenses (I am Dutch) or is this being pound foolish? What is the rationale of separating the mail server from the 'www' server apart from the intuitive 'neatness' appeal?

• HTTP Subdomain Redirect to HTTPS automatically. Why?

  - by user139062

  I have 2 websites deployed in IIS 7.5 Express. The first website is the PRODUCTION website and the second is the TEST website. In the PRODUCTION website, I added an HTTPS binding and Require SSL so it is normal that it will force to redirect from HTTP to HTTPS. In the TEST website, I didn't add HTTPS binding and the Require SSL is disabled but I wonder why it still force to redirect from HTTP to HTTPS. Any idea why this happen? By the way, the PRODUCTION site uses the main domain (www.maindomain.com) and the TEST site uses only sub-domain (test.maindomain.com). I don't want the sub-domain to only use HTTP, not HTTPS. Thank you in advance.

• How can you import a root certificate to a machine level store in Windows 7

  - by ReluctantAdmin01

  I have a service (Running as local system) that uses an SSL connection. Currently this connection fails because the remote host used a private CA to sign it's certificate. For previous operating systems, I used to use the certificate manager to import the CA cert into the local machine's Trusted Root certificates store. Though I can do the steps with a windows 7 machine, it seems after a reboot that the imported certificates are gone. Here are the steps I'm doing in Windows 7: Open mmc Add Certificates Snap-in for Local Machine Navigate to Third-Party Root Certification Authorities/Certificates Import Root CA Cert. The certificate seems to work fine, using internet explorer or the service to test the SSL connection works, but after a reboot it seems like the change is reverted.

• Apache will not stop/start gracefully

  - by ddjammin

  CentOs 6 64bit running apache 2.2.15-29.el6.centos. When I try to stop/start or restart httpd I get an error that says it has failed. A tail of the error log is below. I also noticed that a httpd.pid file is not created even though it is configured in the main conf file. If I set selinux to permissive, it works just fine. I do not want to run it with selinux disabled. If I delete the SSL_Mutex file it will start. HTTPD was running fine until I tried to add the ssl configuration. I copied over the ssl.conf file from a working server into the conf.d folder. I also copied a sslcert folder into the conf folder. It contains the certs, key, csr and password file. I think the problem has to do with the selinux context for the sslcert folder that was copied but I am not certain and not sure how to fix it. Below is the security context for the sslcert folder after executing restorecon -R sslcert ls -Z -rw-r--r--. root root system_u:object_r:httpd_config_t:s0 httpd.conf -rw-r--r--. root root system_u:object_r:httpd_config_t:s0 magic **drwxr-xr-x. root root system_u:object_r:httpd_config_t:s0 sslcert** tail -f /var/log/httpd/error_log [Thu Oct 17 13:33:19 2013] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) [Thu Oct 17 13:33:20 2013] [notice] Digest: generating secret for digest authentication ...

• use local ip and maintain ssl warning free [duplicate]

  - by Timothy Clemans

  This question already has an answer here: Loopback to forwarded Public IP address from local network - Hairpin NAT 6 answers I have a public facing website for a doctor's office for accessing the medical record. I'm using SSL. The server is at the doctor's office. When I access the website on the same network as the server I want the DNS to point to the local IP address. I don't want to do a HTTP redirect to the local ip because of the scary SSL warning. What's the recommended way of doing this?

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

• web application with secured sections, sessions and related trouble

  - by spirytus

  I would like to create web application with admin/checkout sections being secured. Assuming I have SSL set up for subdomain.mydomain.com I would like to make sure that all that top-secret stuff ;) like checkout pages and admin section is transferred securely. Would it be ok to structure my application as below? subdomain.mydomain.com adminSectionFolder adminPage1.php adminPage2.php checkoutPagesFolder checkoutPage1.php checkoutPage2.php checkoutPage3.php homepage.php loginPage.php someOtherPage.php someNonSecureFolder nonSecurePage1.php nonSecurePage2.php nonSecurePage3.php imagesFolder image1.jpg image2.jpg image3.jpg Users would access my web application via http as there is no need for SSL for homepage and similar. Checkout/admin pages would have to be accessed via https though (that I would ensure via .htaccess redirects). I would also like to have login form on every page of the site, including non-secure pages. Now my questions are: if I have form on non-secure page e.g http://subdomain.mydomain.com/homepage.php and that form sends data to http://subdomain.mydomain.com/loginPage.php, is data being send encrypted as if it were sent from https://subdomain.mydomain.com/homepage.php? I do realize users will not see padlock, but browser still should encrypt it, is it right? If on secure page loginPage.php (or any other accessed via https for that instance) I created session, session ID would be assigned, and in case of my web app. something like username of the logged in user. Would I be able to access these session variable from http://subdomain.mydomain.com/homepage.php to for example display greeting message? If session ID is stored in cookies then it would be trouble I assume, but could someone clarify how it should be done? It seems important to have username and password send over SSL. Related to above question I think.. would it actually make any sense to have login secured via SSL so usenrame/password would be transferred securely, and then session ID being transferred with no SSL? I mean wouldnt it be the same really if someone caught username and password being transferred, or caught session ID? Please let me know if I make sense here cause it feels like I'm missing something important. EDIT: I came up with idea but again please let me know if that would work. Having above, so assuming that sharing session between http and https is as secure as login in user via plain http (not https), I guess on all non secure pages, like homepage etc. I could check if user is already logged in, and if so from php redirect to https version of same page. So user fills in login form from homepage.php, over ssl details are send to backend so probably https://.../homepage.php. Trying to access http://.../someOtherPage.php script would always check if session is created and if so redirect user to https version of this page so https://.../someOtherPage.php. Would that work? 4.To avoid browser popping message "this page contains non secure items..." my links to css, images and all assets, e.g. in case of http://subdomain.mydomain.com/checkoutPage1.php should be absolute so "/images/image1.jpg" or relative so "../images/image1.jpg"? I guess one of those would have to work :) wow that's long post, thanks for your patience if you got that far and any answers :) oh yeh and I use php/apache on shared hosting

• pyOpenSSL and the WantReadError

  - by directedition

  I have a socket server that I am trying to move over to SSL on python 2.5, but I've run into a snag with pyOpenSSL. I can't find any good tutorials on using it, so I'm operating largely on guesses. Here is how my server sets up the socket: ctx = SSL.Context(SSL.SSLv23_METHOD) ctx.use_privatekey_file ("mykey.pem") ctx.use_certificate_file("mycert.pem") sock = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) addr = ('', int(8081)) sock.bind(addr) sock.listen(5) Here is how it accepts clients: sock.setblocking(0) while True: if len(select([sock], [], [], 0.25)[0]): client_sock, client_addr = sock.accept() client = ClientGen(client_sock) And here is how it sends/receives from the connected sockets: while True: (r, w, e) = select.select([sock], [sock], [], 0.25) if len(r): bytes = sock.recv(1024) if len(w): n_bytes = sock.send(self.message) It's compacted, but you get the general idea. The problem is, once the send/receive loop starts, it dies right away, before anything has been sent or received (that I can see anyway): Traceback (most recent call last): File "ClientGen.py", line 50, in networkLoop n_bytes = sock.send(self.message WantReadError The manual's description of the 'WantReadError' is very vague, saying it can come from just about anywhere. What am I doing wrong?

• iPhone Custom CA certificate for an application which uses NSURLConnection?

  - by jr

  I have an application which is communicating with many different sites and each site has its own SSL certificate signed by our own internal CA. Doing this prevents us the need from purchasing SSL certificates for each site (hundreds or thousands) and is more secure then using a wildcard certificate with a shared key on each of those sites. So, basically using a CA certificate is the only way. Right now, I have a mobileprovision file which will install the CA certificate as a profile on the phone. When our iPhone application launches if it gets an SSL Certificate error it redirects to a this mobile provision file via Safari and the user will be prompted to install the CA. The problem is that I am concerned that the Apple AppStore might deny my app for doing this (Just some feedback from other developers at this point), and I wanted to research other ways to accomplish this. Basically what I need to accomplish is allow an SSL connection which will verify against a custom CA certificate which will be embedded in my application. This will make the CA certificate active for only the calls I make. I am using the standard NSURLConnection methods in order to communicate with the service. Is this possible? Can someone show me how to load the CA (what form PEM?) and add it to the list of trusted CA certificates for my application? If that is not possible what other options do I have? Just trusting all certificates isn't really any option, we want to prevent man in the middle attacks and only trust our CA issued certificates. Thanks!

• Log in to subdomain via main domain

  - by Mattias

  I have a website, available through multiple domainnames. like www.domain1.com .... www.domain5.com All my customers have their own subdomain. like: customer1.domain1.com customer2.domain1.com .... customer351.domain4.com Currently i dont use SSL, each customer log in their own account via their sub domain. I want to change this, and make all customers log in on a central log in page, that would use SSL, for example. https://login.domain1.com And somehow redirect each user to the correct sub domain adress. (Sub domain that don't use SSL) How do I do this, and maintain security? One idea i had: Login - add random value somewhere in the database, Redirect to subdomain, with querystring the randomvalue. And after that the session takes care of it, Each value can be used once only.. But how secure is that? I guess someone would ask the question "why?" to me. Because SSL costs money. And unfortunately i dont have a lot of it. :D Thanks for your time!

• 502: proxy: pass request body failed

  - by Apikot

  Sometimes I get the following error (in apache's error.log) when viewing my site over https: (502)Unknown error 502: proxy: pass request body failed to xxx.xxx.xxx.xxx:443 I'm not entirely sure what this is and why it happens, it's also not consistent. The request route is: Browser Proxy server (apache with mod_proxy + mod_ssl) Load balancer (aws) Web server (apache with mod_ssl) The configuration on the proxy server is as follows: <VirtualHost *:443> ProxyRequests Off ProxyVia On ServerName www.xxx.co.uk ServerAlias xxx.co.uk <Directory proxy:*> Order deny,allow Allow from all </Directory> <Proxy *> AddDefaultCharset off Order deny,allow Allow from all </Proxy> ProxyPass / balancer://cluster:443/ lbmethod=byrequests ProxyPassReverse / balancer://cluster:443/ ProxyPreserveHost off SSLProxyEngine On SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /var/www/vhosts/xxx/ssl/www.xxx.co.uk.cert SSLCertificateKeyFile /var/www/vhosts/xxx/ssl/www.xxx.co.uk.key <Proxy balancer://cluster> BalancerMember https://xxx.eu-west-1.elb.amazonaws.com </Proxy> </VirtualHost> Any idea what the issue might be?

• Apache Reverse proxy for intranet and other integrated application on intranet

  - by user1433448

  I'm trying to configure a reverse proxy (ssl) with apache 2.2 in Debian Squeeze, but I have some problems, specially with some path absolute and with https I'll try to detail what I have made and what I'm trying to configure I have a server Debian Squeeze with apache2.2 + mod_proxy_html with: # apt-get install libapache2-mod-proxy-html libxml2-dev # a2enmod proxy # a2enmod proxy_http # a2enmod proxy_html # a2enmod headers After that I have configured a virtual host with: reverse_proxy_ssl.conf I'm trying to configure to allow access of our intranet from internet with a reverse proxy (apache that is located in DMZ). With this configuration domain.com/intranet works correctly and we can access to intranet, but we have one problem when from domain.com/intranet we need to use another internal application that is called from intranet with absolute path ( https://192.168.10.25/application/) and from internet appears that try to access with internal ip, and this link es incorrect from external site We only need to access from intranet to multiple internal application that are in external server and we like to restrict to minimal access from internet. All the application that are in the smae server of intranet are working. The second problem is with https and reverse proxy in our firewall appears some errors with packets (not valid packets), and with https seems to work. What can I do to solve this problems (absolute path and ssl problem) Thanks
