I have a VPS. How do I connect to my server through HTTPS protocol and redirect my browser connections to the HTTPS connection?
Currently I use SSH tunnel but it's too slow.

I'm using Squid as proxy server and Stunnel as SSL wrapper. It has very good performance due to caching.
After installing Squid, follow Squid Documentations and configure it. Here is sample configuration:
http_port 3193 transparent cache_dir ufs /var/cache/squid 128 16 128 cache_mem 1 MB maximum_object_size_in_memory 512 KB maximum_object_size 1 MB visible_hostname hostname.com hierarchy_stoplist cgi-bin ? refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 10.0.0.0/8 # RFC 1918 possible internal network acl localnet src 172.16.0.0/12 # RFC 1918 possible internal network acl localnet src 192.168.0.0/16 # RFC 1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT auth_param basic program /usr/libexec/squid/pam_auth auth_param basic children 5 auth_param basic realm Squidy auth_param basic credentialsttl 4 hours acl password proxy_auth REQUIRED http_access allow manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow password http_access allow localhost http_access allow localnet http_access deny all via off forwarded_for off request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all
It listens port
3193 tcp. Then caching options come, Some acl commands and
auth_param for PAM authentication (You probably don't want open proxy and lost your VPS for spam reports).
request_header_access lines are not required. They give you better anonymity.
Install stunnel on server. Here is sample configuration:
setuid = stunnel setgid = stunnel CAfile = /etc/stunnel/certs.pem CRLfile = /etc/stunnel/crls.pem [proxy] accept = 8888 connect = 127.0.0.1:3193
Probably certification files made on stunnel installation. check the file path in
CAfile. It simply listens to port
8888 tcp and redirects decrypted stream to Squid. So let be sure it's reachable:
iptables -I INPUT 1 -p tcp --dport 8888 -j ACCEPT
You don't need to squid listening port be world reachable anymore.
Install stunnel on your local machine and change this configuration to your needs:
setuid = stunnel setgid = stunnel pid = /var/run/stunnel/stunnel.pid [poxy] accept = 8123 connect = server_ip:8888 client = yes libwrap = no
Replace server_ip with appropriate value. then start Squid on server and Stunnel on client and server. set proxy as
localhost:8123 in your browser. If everything work, you must be prompted for username and password.
Is the https server apache? I don't fully understand your situation, but if you have mod_proxy, you might able to do what you want.
I have never set up anything on a virtual host, but here is some information on general HTTPS:
HTTPS uses a combo of HTTP and SSL (see the wikipedia article here: http://en.wikipedia.org/wiki/HTTP_Secure). HTTPS isn't really its own protocol per-se but rather normal HTTP running on an SSL tunnel.
HTTPS uses CA's (Certificate Authories) and PKI (Public Key Infrastructure) to ensure that users can 'trust' the site. You must create a public key certificate for your web server, and that must be signed by a trusted CA (such as VeriSign). To get a trusted certificate it can cost you a yearly fee to maintain.
If you don't go through a trusted CA, users will get a warning when they attempt to connect to your site. This can often times lead users to stray from your site because they might see it as a security risk.
Also, keep in mind that while HTTP uses port 80 by default, HTTPS uses 443 so if you have any port forwarding/port blocking you will have to ensure that is open for you to connect. To use HTTPS you will also have to ensure you type it into the URL when you navigate to the site, otherwise it will likely default to using HTTP.
EDIT: Here is a good introduction to how HTTPS operates: http://securityworkshop.blogspot.com/2009/01/how-httpsssl-works-part-1-basics.html
I do something like this using OpenVPN. My laptop and cellphone can connect to my server at home using SSL over a TCP connection on port 443. This is really useful when I'm at stodgy places that don't let you use any ports besides 80 and 443. Here's a simple configuration that accomplishes this on the server:
port 443 proto tcp dev tun server 10.44.3.0 255.255.255.0 ca ca.crt cert cloud.crt key cloud.key dh dh2048.pem script-security 2 push "redirect-gateway"
Then you tell the server to perform NAT on packets coming from VPN clients:
iptables -t nat -A POSTROUTING -s 10.44.3.0/24 -o eth0 -j MASQUERADE
After I get connected, the networking route on my portable device looks like this:
briankb@ubuntu:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.94.0.9 0.0.0.0 UG 0 0 0 tun0 22.214.171.124 0.0.0.0 255.255.255.128 U 1 0 0 eth0 10.94.0.1 10.94.0.9 255.255.255.255 UGH 0 0 0 tun0 10.94.0.9 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 126.96.36.199 188.8.131.52 255.255.255.255 UGH 0 0 0 eth0
The first line says that default gateway of the client is the VPN server, so all traffic is sent over it. The next line is the subnet I'm currently using (college wifi). The third and fourth line are the VPN subnet/route, and the last line says use the current WAN interface to send packets to the VPN server.
For instructions on setting up OpenVPN, see the How to guide.
My crystal ball says you should take a look at http://www.stunnel.org/static/stunnel.html
In case the ball is wrong, it won't hurt anyways.
Simply enable HTTPS and
mod_alias in Apache, and add a redirect rule like the following:
<VirtualHost *:80> . . . Redirect permanent / https://yoursite.com/ </VirtualHost>
The default configuration varies between OSes/distributions, so I can't be more specific than that. It's better to specify your OS and software versions on the questions so you can get better answers ;-).
Connect to your server through SSH and set up port forwarding:
ssh -L 80:localhost:80 username@hostname. Remote port 80 (your webserver) will be tunneled over SSH to you PC's port 80. Now point your browser to http://localhost/
You may have to extend a line in your /etc/hosts file: 127.0.0.1 hostname
