Top Forums UNIX for Advanced & Expert Users Passing credentials via .netric file in Linux Post 302963190 by hicksd8 on Friday 25th of December 2015 03:55:22 AM

The two things to check with the use of .netrc are the syntax of the file content and the access rights of the file itself.

Here is an excerpt from some documentation I wrote several years ago but nothing has changed:

*****

The contents of the /.netrc file would, for example, be:-

machine plymsql login administrator password memorandum

NOTE: .netrc must have read/write access for the owner ONLY. If other users have read access it may fail to work and ftp will not auto-connect. Therefore, since in this case the user is root, should the file be re-created it must be set as follows:-
cd / <or cd to the home directory of the user under which the job is running>
chown <userid> .netrc
chmod 600 .netrc <giving read/write to only the owner (userid)>

If ftp finds the target nodename listed it uses the login name and password given to create an ftp connection to the target. Of course, this userid/password combination MUST give the process sufficient credentials and access rights to allow the reading/writing required to complete the required tasks. If the system manager changes the respective user account or password without reflecting this in /.netrc it will cause the whole ftp phase of the scripts to fail.

*****

Check these out and report back your progress, or lack of.

You can check out the .netrc functionality interactively by just entering "ftp <nodename>" at the command line. The ftp session should connect immediately without entering credentials. If it doesn't the .netrc mechanism isn't working. Ensure that the nodename can be resolved, eg. by an entry in /etc/hosts or other means such as DNS.

NAME
netrc, .netrc - Specifies automatic login information for ftp SYNOPSIS
$HOME/.netrc DESCRIPTION
The .netrc file contains the information used by the automatic login (autologin) feature of the ftp command. It is a hidden file in your home directory and must be owned by the user logging in, or by the root user. If the .netrc file contains a login password, the file's permissions must be set to 600 (read and write by owner only). The .netrc file can contain the following entries (separated by spaces, tabs, or newlines): Where host is the name of a remote host. This entry begins the definition of the autologin process for the specified host. All following entries up to the next machine entry or the end of the file apply to that host. This is the same as machine, except that default matches any name. There can be only one default token, and it must appear after all machine tokens. This is normally used as follows: default login anonymous password user@site The preceding command line gives the user automatic anonymous ftp login to machines not specified in .netrc. This can be overriden by using the -n flag to disable autologin. Where user is the username to use at the remote host. If this entry is found, the autologin process initiates a login using the specified name. If this entry is missing, the autologin process fails. Where password is the login password to be used. The autologin process supplies this password to the remote server. A login password must be established at the remote host and that pass- word must be entered in this file, or the autologin process fails and you are prompted for the login password. Where password is the account password to be used. If this entry is found and an account password is required at the remote host, the autologin process supplies the password to the remote server. If the remote host requires an account password but this entry is missing, the autologin process prompts for the account password. Where macro is the name of an ftp subcommand macro. The macro definition starts on the following line and is defined to contain all of the following ftp subcommands up to the next blank line. If the macro is named init, ftp executes the macro upon successful completion of the autologin process. FILES
