Proxy 403
a question Anybody can answer The best answers are voted up and rise to the top How to SSH an outside server from a computer which is behind a proxy firewall? up vote 4 down vote favorite 3 I access the Internet proxy 403 forbidden putty through an HTTP proxy firewall at college. And I need to login to a computer, via SSH, which is outside our network. I tried it as Linux command and on Windows using PuTTY. I also configured PuTTY to use our server's address. But still, "Proxy error: 403 forbidden" pops up. They must've blocked SSH access to outside systems. (college systems as accessible). I can SSH a web server (not the proxy server) at the college, which I use to browse proxy-free by tunneling. Now this proxy error 403 tunnel or ssl forbidden server allows to browse restricted sites, but still no SSH. Any workaround, please? ssh proxy firewall putty tunnel share|improve this question edited Jun 5 '10 at 21:46 quack quixote 31.3k1068114 asked Nov 5 '09 at 17:11 Karan 53125 add a comment| 3 Answers 3 active oldest votes up vote 7 down vote It may be that the proxy is only allowing access to HTTP/HTTPS ports (80 or 443). I've worked around that by changing the SSH server to listed on port 443. That made the proxy I had to go through allow the connection, but if you can't change the SSH server then you may be out of luck. share|improve this answer answered Nov 5 '09 at 17:34 shf301 6,8761920 add a comment| up vote 0 down vote If you can bypass the proxy for web, you can bypass it for SSH by tunneling SSH: ssh -L 55555:remote-computer-to-ssh-to:22 login@webserver and once that's in place: ssh -oPort=55555 remote-login@localhost This will give you an SSH tunnel to the webserver machine, which then forwards your SSH traffic to the remote machine. share|improve this answer answered Nov 5 '09 at 18:53 blahdiblah 1,61411228 add a comment| up vote 0 down vote @blahdiblah from what I understand his problem is not SSHing to the local webserver, its SSHing out of his network. If they are blocking outgoing connections to port 22 it doesnt matter were he tries to SSH from, it will be blocked. Unless the firewall would be setup to allow the webserver to in
by the URL is forbidden for some reason. This indicates a fundamental access problem, which may be difficult to resolve because the HTTP protocol allows the Web server to give this response

without providing any reason at all. So the 403 error is equivalent to a blanket postman 'NO' by the Web server - with no further discussion allowed. By far the most common reason for this error is that directory browsing is forbidden for the Web site. Most Web sites want you to navigate using the URLs in the Web pages for that site. They do not often allow you to browse the file http://superuser.com/questions/66258/how-to-ssh-an-outside-server-from-a-computer-which-is-behind-a-proxy-firewall directory structure of the site. For example try the following URL (then hit the 'Back' button in your browser to return to this page): http://www.checkupdown.com/accounts/grpb/B1394343/ This URL should fail with a 403 error saying "Forbidden: You don not have permission to access /accounts/grpb/B1394343/ on this server". This is because our CheckUpDown Web site deliberately does not want you to browse directories - you have to navigate from one specific Web page to another http://www.checkupdown.com/status/E403.html using the hyperlinks in those Web pages. This is true for most Web sites on the Internet - their Web server has "Allow directory browsing" set OFF. Fixing 403 errors - general You first need to confirm if you have encountered a "No directory browsing" problem. You can see this if the URL ends in a slash '/' rather than the name of a specific Web page (e.g. .htm or .html). If this is your problem, then you have no option but to access individual Web pages for that Web site directly. It is possible that there should be some content in the directory, but there is none there yet. For example if your ISP offers a 'Home Page' then you need to provide some content - usually HTML files - for the Home Page directory that your ISP assigns to you. Until the content is there, anyone trying to access your Home Page could encounter a 403 error. The solution is to upload the missing content - directly yourself or by providing it to your ISP. Once the content is in the directory, it also needs to be authorised for public access via the Internet. Your ISP should do this as a matter of course - if they do not, then they have misse

Here's the npm ticket: npm/npm#2866 I have set up my .npmrc file to have settings for our corporate proxy: proxy = http://user:password@proxy:8080/ proxy error 403 https-proxy = http://user:password@proxy:8080/ Running any npm command using these settings fails. As a workaround, I had to change the registry to HTTP instead of HTTPS: registry = http://registry.npmjs.org/ Most things seem to work fine with this, except if I try to install something that has dependencies listed using HTTPS. One example for this is Yeoman (https://github.com/yeoman/yeoman), which lists two dependencies in package.json using HTTPS: https://nodeload.github.com/cowboy/grunt/tarball/0ba6d4b529 https://nodeload.github.com/yeoman/generators/tarball/282b0b4c51 Downloading these fails miserably with the following error: npm ERR! fetch failed https://nodeload.github.com/cowboy/grunt/tarball/0ba6d4b529 npm ERR! fetch failed https://nodeload.github.com/yeoman/generators/tarball/282b0b4c51 npm ERR!

Status codes 401 (Unauthorized) and 403 (Forbidden) have distinct meanings. A 401 response indicates that access to the resource is restricted, and the request did not provide any HTTP authentication. It is possible that a new request for the same resource will succeed if authentication is provided. The response must include an HTTP WWW-Authenticate header to prompt the user-agent to provide credentials. If valid credentials are not provided via HTTP Authorization, then 401 should not be used.[1] A 403 response generally indicates one of two conditions: Authentication was provided, but the authenticated user is not permitted to perform the requested operation. The operation is forbidden to all users. For example, requests for a directory listing return code 403 when directory listing has been disabled. 403 substatus error codes for IIS[edit] en.Wikipedia error message The following nonstandard code are returned by Microsoft's Internet Information Services and are not officially recognized by IANA. 403.1 - Execute access forbidden.[2] 403.2 - Read access forbidden.[2] 403.3 - Write access forbidden.[2] 403.4 - SSL required.[2] 403.5 - SSL 128 required.[2] 403.6 - IP address rejected.[2] 403.7 - Client certificate required.[2] 403.8 - Site access denied.[2] 403.9 - Too many users.[2] 403.10 - Invalid configuration.[2] 403.11 - Password change. 403.12 - Mapper denied access. 403.13 - Client certificate revoked. 403.14 - Directory listing denied. 403.15 - Client Access Licenses exceeded. 403.16 - Client certificate is untrusted or invalid. 403.17 - Client certificate has expired or is not yet valid. 403.18 - Cannot execute request from that application pool. 403.19 - Cannot execute CGIs for the client in this application pool. 403.20 - Passport logon failed. 403.21 - Source access denied. 403.22 - Infinite depth is denied. 403.502 - Too many requests from the same client IP; Dynamic IP Restriction limit reached.
