NAME

librmt - remote magtape protocol client interface library

SYNOPSIS

cc [ flag ... ] file ... -lrmt -lsocket -lnsl [ library ... ]

#include <schily/librmt.h>

DESCRIPTION

Functions in this library provide an interface to a remote tape server program.

This implementation takes care of RMT protocol VERSION 1 that is needed in case that rmt client and rmt server do not run on the same OS and use a CPU with the same bit width and byte order.

In addition, this implementation supports a GNU extension that allows to use open(2) flags beyond O_RDONLY, O_WRONLY, O_RDWR.

ENVIRONMENT

RSH

If the RSH environment is present, the remote connection will not be created via rcmd(3) but by calling the program pointed to by RSH. Use e.g. RSH=/usr/bin/ssh to create a secure shell connection.

If the environment RSH is empty, then the default rcmd(3) is used even in case rmtrsh(3) has been called.

RMT

If the RMT environment is present, the remote tape server will not be the program /etc/rmt but the program pointed to by RMT.

If the environment RMT is empty, then the default /etc/rmt is used even in case rmtrmt(3) has been called.

Note that the remote tape server program name will be ignored if you log in using an account that has been created with a remote tape server program as login shell.

INTERFACES

rmtinit(3), rmtdebug(3), rmtrmt(3), rmtrsh(3), rmthostname(3), rmtfilename(3), rmtgetconn(3), rmtopen(3), rmtioctl(3), rmtclose(3), rmtread(3), rmtwrite(3), rmtseek(3), rmtxstatus(3), rmtstatus(3), _mtg2rmtg(3), _rmtg2mtg(3)
