/etc/shells?

Hanry Zhou — Tue, 15 Jul 2003 21:29:58 GMT

Can anybody please let me know where I can find the corresponding file of /etc/shells on Solaris servers?

Thanks,

Hi Hanry,

I think its the same file but it might not created by default. You can just create the file manually or run the getusershell(3C) system call to get the list of supported shells. See the following Sun URL :

James.

Sun's convention is a little different. They have a library function called getusershell() that will list the standard shells. You can create your own /etc/shell and it will augment those listed by getusershell().

http://devrsrc1.external.hp.com/STKLI/man/11iv1.5/shells_4.html - on hp.

as to solaris see here:http://docs.sun.com/db/doc/805-3480/6j3ahiigm?a=view

in particular:'This file is not included in the standard release, so it must be added if users are to be allowed to use .forward files to forward mail to a program or to a file. It is possible to create the file by hand by using grep to identify all of the shells listed in your password file, then entering them manually in the file, but it is easier to use the procedure below, which employes a script that can be downloaded'
Just remembered because once (in previous unix life :)) used to mess with .forward.

Ok,

thanks for messages,
Now it comes to my stupid questions, why do I need /etc/shells? seems the system is working ok without it?

With so many shells cropping up everywhere, this is a control a sysadmin has on the users shells, so you can define what are the shells that are authorized to be run in a server.

man getusershell

DESCRIPTION
The getusershell() function returns a pointer to a legal
user shell as defined by the system manager in the file
/etc/shells. IF /etc/shells DOES NOT EXIST, the following <<<<<
Note
locations of the standard system shells are used in its
place:
/usr/bin/sh /usr/bin/csh
/usr/bin/ksh /usr/bin/jsh
/bin/sh /bin/csh
/bin/ksh /bin/jsh
/sbin/sh

The idea is to give a greater degree of control over who can use ftp -
for example it's possible to turn off access completely just by creating
an empty /etc/shells
