Why does the connection hang when I connect to my SSL-aware Apache server?

SSL/TLS Strong Encryption: FAQ - Apache HTTP Server
Because you connected with HTTP to the HTTPS port, i.e. you used an URL of the form ''http://'' instead of ''https://''. This also happens the other way round when you connect via HTTPS to a HTTP port, i.e. when you try to use ''https://'' on a server that doesn't support SSL (on this port). Make sure you are connecting to a virtual server that supports SSL, which is probably the IP associated with your hostname, not localhost (127.0.0.1). There can be various reasons.

SSL/TLS Strong Encryption: FAQ - Apache HTTP Server
This can happen when you try to connect to a HTTPS server (or virtual server) via HTTP (eg, using http://example.com/ instead of https://example.com). It can also happen when trying to connect via HTTPS to a HTTP server (eg, using https://example.com/ on a server which doesn't support HTTPS, or which supports it on a non-standard port). Make sure that you're connecting to a (virtual) server that supports SSL. This error can be caused by an incorrect configuration.

Why does an SSL connection sometimes hang the browser?

Open Channel Foundation: FAQ - LDAP Browser Editor
Most likely this occurs when the ldap port number specified in the connection windows was not a SSL port. If non-secure socket is used to connect to a server's SSL socket, then the application using the non-secure socket will hang. This is a characteristic of the SSL protocol. Open Channel Software runs entirely on Open Source Software. We return value to the Software community in the form of services and original software.

Using an SSL network connection, how do I connect to my server?

Net::LDAP::FAQ - Frequently Asked Questions about Net::LDAP ...
This class is a subclass of Net::LDAP so all the normal Net::LDAP methods can be used with a Net::LDAPS object; see the documentation for Net::LDAP to find out how to query a directory server using the LDAP protocol. The connection to the server is created when you create a new Net::LDAPS object, e.g. $ldaps = Net::LDAPS->new($server, port => '10000', verify => 'require', capath => '/usr/local/cacerts/', ); Starting with version 0.

Why doesn't Apache include SSL?

Apache Server Frequently Asked Questions
SSL (Secure Socket Layer) data transport requires encryption, and many governments have restrictions upon the import, export, and use of encryption technology. If Apache included SSL in the base package, its distribution would involve all sorts of legal and bureaucratic issues, and it would no longer be freely available. Also, some of the technology required to talk to current clients using SSL is patented by RSA Data Security, who restricts its use without a license.

Is there a difference on startup between a non-SSL-aware Apache and an SSL-aware Apache?

SSL/TLS Strong Encryption: FAQ - Apache HTTP Server
Yes. In general, starting Apache with mod_ssl built-in is just like starting Apache without it. However, if you have a passphrase on your SSL private key file, a startup dialog will pop up which asks you to enter the pass phrase. Having to manually enter the passphrase when starting the server can be problematic - for example, when starting the server from the system boot scripts. In this case, you can follow the steps below to remove the passphrase from your private key.

When I try to connect to a server via FTP, I get the error 'connection timeout.' How can I fix this?

Internet Archive Frequently Asked Questions
This error is caused by a setting in your FTP client, that limits the amount of time your FTP client will wait for a server to respond. In order to fix this problem, increase the "server timeout" setting; a setting of 180 seconds should be enough time to connect to the archive.org servers. If you use SmartFTP, the "server timeout" setting can be found in Tools > Settings > Connections.

Why does FTP hang when trying to connect to a FTP server protected by Firewall-1?

FTP uses two connections, port 21 for FTP commands and another port for data traffic. Some stateful packet filters such as Checkpoint’s Firewall-1 expect a fixed data port for the data connection. By default, the OS will assign an ephemeral port number for the data connection. If Firewall-1 is configured to allow only a fixed port number, then you can configure ftproxy to use a fixed data port with the client side data port directive (csdport).

Seems like there is a difference on startup between the original Apache and an SSL-aware Apache?

SSL/TLS Strong Encryption: FAQ - Apache HTTP Server
Yes, in general, starting Apache with a built-in mod_ssl is just like starting an unencumbered Apache, except for the fact that when you have a pass phrase on your SSL private key file. Then a startup dialog pops up asking you to enter the pass phrase. To type in the pass phrase manually when starting the server can be problematic, for instance when starting the server from the system boot scripts.

Why does initial SSL connection take a while to establish?

Open Channel Foundation: FAQ - LDAP Browser Editor
The very first time a secure connection is established Java must create a secure seed required for the SSL connection. This is a very computationally expensive process and may take up to a few seconds on certain platforms. However, the seed only needs to be computed once per session.

Is Apache-SSL Y2K Compliant?

Apache-SSL
Apache-SSL does not add any date processing to the underlying components, so does not affect the overall compliance of your system. The main component, Apache, has this to say on the matter. You should also check your operating system, hardware and any other modules you include.

How can I get my script's output without Apache buffering it? Why doesn't my server push work?

Apache Server Frequently Asked Questions
of Apache 1.3, CGI scripts are essentially not buffered. Every time your script does a "flush" to output data, that data gets relayed on to the client. Some scripting languages, for example Perl, have their own buffering for output - this can be disabled by setting the $| special variable to 1. Of course this does increase the overall number of packets being transmitted, which can result in a sense of slowness for the end user. Prior to 1.

Why can't I publish to my Apache server using PUT on Netscape Gold and other programs?

Apache Server Frequently Asked Questions
Because you need to install and configure a script to handle the uploaded files. This script is often called a "PUT" handler. There are several available, but they may have security problems. Using FTP uploads may be easier and more secure, at least for now. For more information, see the Apache Week article Publishing Pages with PUT.

Why does ssh hang on exit?

OpenSSH FAQ
I upgraded to OpenSSH 3.1 and X11 forwarding stopped working. Starting with OpenSSH 3.1, the sshd x11 forwarding server listens on localhost by default; see the sshd X11UseLocalhost option to revert to prior behaviour if your older X11 clients do not function with this configuration. In general, X11 clients using X11 R6 should work with the default setting. Some vendors, including HP, ship X11 clients with R6 and R5 libs, so some clients will work, and others will not work.
