ssh-socks5-proxy-connect(1)					   User Commands				       ssh-socks5-proxy-connect(1)

NAME
ssh-socks5-proxy-connect - Secure Shell proxy for SOCKS5 SYNOPSIS
/usr/lib/ssh/ssh-socks5-proxy-connect [-h socks5_proxy_host] [-p socks5_proxy_port] connect_host connect_port DESCRIPTION
A proxy command for ssh(1) that uses SOCKS5 (RFC 1928). Typical use is where connections external to a network are only allowed via a socks gateway server. This proxy command does not provide any of the SOCKS5 authentication mechanisms defined in RFC 1928. Only anonymous connections are possi- ble. OPTIONS
The following options are supported: -h socks5_proxy_host Specifies the proxy web server through which to connect. Overrides the SOCKS5_SERVER environment variable. -p socks5_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the SOCKS5_PORT environment variable. OPERANDS
The following operands are supported: socks5_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy. socks5_proxy_port The numeric port number to connect to on socks5_proxy_host. connect_host The name of the remote host to which the socks gateway is to connect you. connect_port The numeric port number of the socks gateway to connect you to on connect_host. EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2). Example 3 shows how the proxy command can be specified on the command line when running ssh(1). Example 1: Setting the proxy from the environment The following example uses ssh-socks5-proxy-connect in ssh_config(4) when the proxy is set from the environment: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect playtime.foo.com 22 Example 2: Overriding proxy environment variables The following example uses ssh-socks5-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22 Example 3: Using the command line The following example uses ssh-socks5-proxy-connect from the ssh(1) command line: example$ ssh -o'ProxyCommand=/usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22' playtime.foo.com ENVIRONMENT VARIABLES
SOCKS5_SERVER Takes socks5_proxy_host operand to specify the default proxy host. SOCKS5_PORT Takes socks5_proxy_port operand to specify the default proxy port. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES

CURLOPT_PRE_PROXY(3)					     curl_easy_setopt options					      CURLOPT_PRE_PROXY(3)

NAME
CURLOPT_PRE_PROXY - set pre-proxy to use SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PRE_PROXY, char *preproxy); DESCRIPTION
Set the preproxy to use for the upcoming request. The parameter should be a char * to a zero terminated string holding the host name or dotted numerical IP address. A numerical IPv6 address must be written within [brackets]. To specify port number in this string, append :[port] to the end of the host name. The proxy's port number may optionally be specified with the separate option CURLOPT_PROXYPORT(3). If not specified, libcurl will default to using port 1080 for proxies. A pre proxy is a SOCKS proxy that curl connects to before it connects to the HTTP(S) proxy specified in the CURLOPT_PROXY option. The pre proxy can only be a SOCKS proxy. The pre proxy string should be prefixed with [scheme]:// to specify which kind of socks is used. Use socks4://, socks4a://, socks5:// or socks5h:// (the last one to enable socks5 and asking the proxy to do the resolving, also known as CURLPROXY_SOCKS5_HOSTNAME type) to request the specific SOCKS version to be used. Otherwise SOCKS4 is used as default. Setting the pre proxy string to "" (an empty string) will explicitly disable the use of a pre proxy. The application does not have to keep the string around after setting this option. DEFAULT
Default is NULL, meaning no pre proxy is used. When you set a host name to use, do not assume that there's any particular single port number used widely for proxies. Specify it! PROTOCOLS
All except file://. Note that some protocols don't do very well over proxy. EXAMPLE
TODO AVAILABILITY
Added in 7.52.0 RETURN VALUE
Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space. SEE ALSO
