TENTACLE_CLIENT(1) Client file transfer protocol TENTACLE_CLIENT(1) NAME
tentacle_client - a client file transfer protocol SYNOPSIS
tentacle_client <options> Tentacle is a client/server file transfer protocol that aims to be: - Executable programs or shell commands - System calls (functions provided by the kernel) - Library calls (functions within program libraries) Tentacle was created to replace more complex tools like SCP and FTP for simple file transfer/retrieval, and switch from authentication mechanisms like .netrc, interactive logins and SSH keys to X.509 certificates. Simple password authentication over a SSL secured connection is supported too. The client and server (TCP port 41121) are designed to be run from the command line or called from a shell script, and no configuration files are needed. Tentacle is now the default file transfer method for Pandora FMS and Babel Enterprise. Tentacle is implemented in Perl and ANSI C (Windows platforms included). You can download it and get more information at the official Sourceforge website http://tentacled.sourceforge.net/. OPTIONS
Tentacle Client options : -a address : Server address (default 127.0.0.1). -c : Enable SSL without a client certificate. -e cert : OpenSSL certificate file. Enables SSL. -f ca : Verify that the peer certificate is signed by a ca. -g : Get files from the server. -h : Show help. -k key : OpenSSL private key file. -p port : Server port (default 41121). -q : Quiet. Do now print error messages. -r number : Number of retries for network operations (default 3). -t time : Time-out for network operations in seconds (default 1s). -v : Be verbose. -w : Prompt for OpenSSL private key password. -x pwd : Server password. EXAMPLES
tentacle_client -a 192.168.1.1 -v /bin/bash Simple file transfer with maximum file size set to 1MB tentacle_client -a 192.168.1.1 -x password -v /bin/bash Simple file transfer with password authentication (not secure) tentacle_client -a 192.168.1.1 -x password -e cert.pem -k key.pem -v /bin/bash Secure file transfer with client certificate and password authentication NOTES
Tentacle requires Perl 5.8 or higher to works SEE ALSO
