PROGRAM:

NAME

curlftpfs - mount a ftp host as a local directory

SYNOPSIS

curlftpfs [options] host path

DESCRIPTION

The program curlftpfs is a tool to mount remote ftp hosts as local directories. It
connects to the host FTP server and maps its directory structure to the path directory.

curlftpfs is powered by libcurl for all transfer-related features. See libcurl(3) for
details. The filesystem part is implemented on top of FUSE. See
http://fuse.sourceforge.net/ for details.

FTP OPTIONS

-h/--help
Print help options.

-v/--verbose
Make libcurl print verbose debug output.

-V/--version
Print curlftpfs, libcurl and fuse versions.

-o Options are specified with a -o flag followed by a comma separated string of
options.

cacert=<file>
(SSL) Pass a string naming a file holding one or more certificates to verify
the peer with.

Note that option is by default set to the system path where libcurl's
cacert bundle is assumed to be stored, as established at build time.

capath=<directory>
(SSL) Tells curlftpfs to use the specified certificate directory to verify
the peer. The certificates must be in PEM format, and the directory must
have been processed using the c_rehash utility supplied with openssl.
Using capath can allow curlftpfs to make connections much more efficiently
than using cacert if the cacert file contains many CA certificates.

cert=<certificate>
(SSL) Tells curlftpfs to use the specified certificate file. The default
format is "PEM" and can be changed with cert_type.

cert_type=<type>
(SSL) Tells curlftpfs what certificate type the provided certificate is in.
PEM, DER and ENG are recognized types.

ciphers=<list of ciphers>
(SSL) Specifies which ciphers to use in the connection. The list must be
syntactically correct, it consists of one or more cipher strings separated
by colons. Commas or spaces are also acceptable separators but colons are
normally used, , - and + can be used as operators. Valid examples of
cipher lists include 'RC4-SHA', ´SHA1+DES', 'TLSv1' and 'DEFAULT'. The
default list is normally set when you compile OpenSSL.

http://www.openssl.org/docs/apps/ciphers.html

codepage=<name>
Sets the encoding the ftp server uses to encode file names.

connect_timeout=<seconds>
Maximum time in seconds that you allow the connection to the server to take.
This only limits the connection phase, once curlftpfs has connected this
option is of no more use.

custom_list=<command>
Command used by curlftpfs to list files. The default is "LIST -a" but some
servers might require extra options, e.g. "LIST -la".

disable_eprt
Tell curlftpfs to disable the use of the EPRT and LPRT commands when doing
active FTP transfers. Curlftpfs will normally always first attempt to use
EPRT, then LPRT before using PORT, but with this option, it will use PORT
right away. EPRT and LPRT are extensions to the original FTP protocol, may
not work on all servers but enable more functionality in a better way than
the traditional PORT command.

disable_epsv
Tell curlftpfs to disable the use of the EPSV command when doing passive FTP
transfers. This is the default.

enable_epsv
Tell curlftpfs to enable the use of the EPSV command when doing passive FTP
transfers. Curlftpfs will first attempt to use EPSV before PASV.

engine=<name>
Select the OpenSSL crypto engine to use for cipher operations. Use:
curl --engine list
to print a list of build-time supported engines. Note that not all
(or none) of the engines may be available at run-time.

ftpfs_debug
Make curlftpfs print lots of debug information. Useful only in conjunction
with the -d option.

ftp_method=<method>
Control what method curlftpfs should use to reach a file on the server. The
method argument should be one of the following alternatives:

multicwd
curlftpfs does a single CWD operation for each path part in the given
URL. For deep hierarchies this means very many commands. This is how
RFC1738 says it should be done. This is the default but the slowest
behavior.

singlecwd
curlftpfs does one CWD with the full target directory and then
operates on the file "normally" (like in the multicwd case).

ftp_port=<address>
Reverses the initiator/listener roles when connecting with ftp. This switch
makes curlftpfs use the PORT command instead of PASV. In practice, PORT
tells the server to connect to the client's specified address and port,
while PASV asks the server for an ip address and port to connect to.
<address> should be one of:

interface
i.e "eth0" to specify which interface's IP address you want to use

IP address
i.e "192.168.10.1" to specify exact IP number

host name
i.e "my.host.domain" to specify machine

- make curlftpfs pick the same IP address that is already used for the
control connection

Disable the attempt to use the EPRT command instead of PORT by using
disable_eprt. EPRT is really PORT++.

httpproxy
Set the proxy type to HTTP. This is the default type.

interface=<name>
Pass a string as parameter. This set the interface name to use as
outgoing network interface. The name can be an interface name, an IP
address or a host name.

iocharset=<name>
Sets the charset used by the client side for codepage to charset
translation. Default: UTF8.

ipv4 If libcurl is capable of resolving an address to multiple IP versions
(which it is if it is ipv6-capable), this option tells libcurl to resolve
names to IPv4 addresses only.

ipv6 If libcurl is capable of resolving an address to multiple IP versions
(which it is if it is ipv6-capable), this option tells libcurl to resolve
names to IPv6 addresses only.

key=<key>
(SSL) Private key file name. Allows you to provide your private key in this
separate file. The default format is "PEM" and can be changed with
key_type.

key_type=<type>
(SSL) Pass a string in the format of your private key. Supported formats
are "PEM", "DER" and "ENG".

The format "ENG" enables you to load the private key from a crypto
engine. In this case key is used as an identifier passed to the engine.
You have to set the crypto engine with engine option. "DER" format key file
currently does not work because of a bug in OpenSSL.

krb4=<level>
Enable kerberos4 authentication and use. The level must be entered and
should be one of 'clear', 'safe', 'confidential' or 'private'. Should you
use a level that is not one of these, 'private' will instead be used.

This option requires that the libcurl library was built with kerberos4
support. This is not very common.

no_verify_hostname
(SSL) Curlftpfs will not verify the hostname when connecting to a SSL
enabled server.

no_verify_peer
(SSL) Curlftpfs will not verify the certificate when connecting to a SSL
enabled server.

pass=<password>
(SSL) Pass phrase for the private key.

proxy=<host[:port]>
Use specified HTTP proxy. If the port number is not specified, it is
assumed at port 1080.

This option overrides existing environment variables that sets proxy to
use. If there's an environment variable setting a proxy, you can set
proxy to "" to override it.

This options implies the proxytunnel option.

Starting with libcurl version 7.14.1, the proxy host can be specified the
exact same way as the proxy environment variables, including protocol
prefix (http://) and embedded user + password.

proxytunnel
Tells curlftpfs to use a tunnel proxy. This option is implied by the proxy
option but you need to set it manually if you use the proxy environment
variable.

proxy_anyauth
Tells curl to pick a suitable authentication method when communicating
with the given proxy. This will cause an extra request/response
round-trip.

proxy_basic
Tells curlftpfs to use HTTP Basic authentication when communicating with the
given proxy. Basic is the default authentication method curlftpfs is used
with proxies.

proxy_digest
Tells curlftpfs to use HTTP Digest authentication when communicating with
the given proxy.

proxy_ntlm
Tells curlftpfs to use HTTP NTLM authentication when communicating with
the given proxy.

proxy_user=<user:password>
Specify user and password to use for proxy authentication.

skip_pasv_ip
Tell curlftpfs to not use the IP address the server suggests in its response
to curlftpfs's PASV command when curlftpfs connects the data connection.
Instead curlftpfs will re-use the same IP address it already uses for the
control connection.

socks4 Set the proxy type to SOCKS4.

socks5 Set the proxy type to SOCKS5.

ssl Make curlftpfs use SSL/TLS for both control and data connections.

sslv3 Forces curlftpfs to use SSL version 3 when negotiating with a remote SSL
server.

ssl_control
Make curlftpfs use SSL/TLS only for the control connection.

ssl_try
Curlftpfs will try to use SSL/TLS for both the control and data connections
but if the server doesn't support it, it will still connect unencrypted.

tcp_nodelay
Turn on the TCP_NODELAY option. See the curl_easy_setopt(3) man page for
details about this option.

tlsv1 (SSL) Forces curlftpfs to use TLS version 1 when negotiating with a remote
TLS server.

transform_symlinks
Append path to the absolute symlinks so that they still point inside the ftp
directory structure. Otherwise those links will very probably be broken.

user=<user:password>
Specify user and password to use for server authentication. Overrides
netrc configuration.

utf8 Try to transfer file list with UTF-8 encoding. Send OPTS UTF8 ON at the
beginning of file list transfer.
