Double ssh tunnel linux10/28/2023 Specify by using -U as above: curl -U user:passwd -x my-proxy:888 Ī comma-separated list of hosts and domains which do not use the proxy can be specified as: curl -noproxy -x my-proxy:888 ![]() Some proxies require special authentication. Get a file from an HTTP server that requires user and password, using the same proxy as above: curl -u user:passwd -x my-proxy:888 Get an ftp file using an HTTP proxy named my-proxy that uses port 888: curl -x my-proxy:888 You can also use both HTTP and SOCKS proxies to transfer files to and from FTP servers. ![]() It does not have special support for FTP proxy servers since there are no standards for those, but it can still be made to work with many of them. ProxyĬurl supports both HTTP and SOCKS proxy servers, with optional authentication. Probably most commonly used with private certificates, as explained below. When using a proxy, you must use the -u style for user and password. Note! According to the URL specification, HTTP URLs can not contain a user and password, so that style will not work when using curl via a proxy, even though curl allows it at other times. You can also ask curl to pick the most secure ones out of the ones that the server accepts for the given URL, by using -anyauth. Without telling which method to use, curl defaults to Basic. HTTP offers many different methods of authentication and curl supports several: Basic, Digest, NTLM and Negotiate (SPNEGO). HTTPĬurl also supports user and password in HTTP URLs, thus you can pick a file like: curl specify user and password separately like in curl -u name:passwd Typically, curl will automatically extract the public key from the private key file, but in cases where curl does not have the proper library support, a matching public key file must be specified using the -pubkey option. Note that the private key may itself be protected by a password that is unrelated to the login password of the remote system this password is specified using the -pass option. This is similar to FTP, but you can use the -key option to specify a private key to use instead of a password. Note that using FTPS:// as prefix is the implicit way as described in the standards while the recommended explicit way is done by using FTP:// and the -ssl-reqd option. It is just like for FTP, but you may also want to specify and use SSL-specific options for certificates etc. To ftp files using name and password, include them in the URL like: curl specify them with the -u flag like curl -u name:passwd Get a web page and store in a local file, make the local file get the name of the remote document (if no file name part is specified in the URL, this will fail): curl -O įetch two files and store them with their remote names: curl -O -O /download.html ![]() Get a web page and store in a local file with a specific name: curl -o thatpage.html Get the main page from an IPv6 web server: curl " Get a file from an SMB server: curl -u "domain\username:passwd" smb:///share/file.txt Get a file from an SSH server using SCP using a private key (password-protected) to authenticate: curl -u username: -key ~/.ssh/id_rsa -pass private_key_password Get a file from an SSH server using SCP using a private key (not password-protected) to authenticate: curl -u username: -key ~/.ssh/id_rsa scp:///~/file.txt Get a file from an SSH server using SFTP: curl -u username s Or use the more appropriate FTPS way to get the same file: curl -ftp-ssl Get a file off an FTPS server: curl ftps:///secrets.txt Get the definition of curl from a dictionary: curl dict:///d:curl Get the all terms matching curl from a dictionary: curl dict:///m:curl Get a directory listing of an FTP site: curl Get a web page from a server using port 8000: curl Get a README file from an FTP server: curl ![]() Get the main page from a web-server: curl
