Description Jason Farrell 2006-11-30 18:04:07 EST
Description of problem:
The restricted bash shell ("rbash") can only be invoke by "bash -r", since the
"rbash" symlink is missing.

Steps to Reproduce:
1. yum install bash       # if not already installed
2. run "rbash"
  
Actual results:
No such file, since it wasn't provided.

Expected results:
restricted bash shell should work via symlink (by inspecting argv[0] from the
symlink, as is done for egrep and other utils)
1) /bin/rbash symlinked to /bin/bash
2) /bin/rbash added to /etc/shells


Additional info:
manually creating the symlink works:

[root@nano tmp]# rpm -q bash
bash-3.1-16.1
[root@nano tmp]# rpm -ql bash | grep rbash
/usr/share/doc/bash-3.1/rbash.0
/usr/share/doc/bash-3.1/rbash.ps
[root@nano tmp]# whereis rbash
rbash:
[root@nano tmp]# whereis egrep
egrep: /bin/egrep /usr/share/man/man1/egrep.1.gz
[root@nano tmp]# ln -s /bin/bash /bin/rbash
[root@nano tmp]# rbash
[root@nano tmp]# cd /
rbash: cd: restricted
