    When attempting to add a host to the hosts list in ZeroShell, I found I was getting the error below:

    Feb 09 11:39,17 ERROR: sh: line 1: R_b2xR4: command not found while adding ",ou=Computers,dc=example,dc=...

    The “R_b2xR4” string is part of a randomly generated password I was using on the device for the “admin” account, the full password being “&R_b2xR4“. Obviously ampersands are reserved characters in UNIX shells, and should not be accepted as valid input for ZeroShell passwords. Either this, or the way in which ZeroShell uses passwords in different flavours of UNIX shells needs to be adapted. 🙂

    Full debug is listed below:

    Same problem still exists in ZS R2.0 RC2.

    It is not possible to add a user or a host if the admin password contains space, &, ! or any other character that the shell will interpret as special.

    As you can see below in chrisfu’s posting, the -w argument of ldapadd is invoked without quotes. Consequently, any password which contains shell special characters or spaces will generate an error.

    The post is 3 years old, however the problem still exist. This should be a trivial fix.


    This also applies to PPPOE password

    took me half an hour to figure that out.


    To make that clear. I tried to set a password for my pppoe connections. this password contains a $. in /tmp/ppp-secrets the $ was replaced by _

    changing /tmp/ppp-secrets with vim was the trick. but this is not a solution
