Re: Restrict users access to ftp and make su to root

Hello,

Many possible scenarios. Start with:

a) Edit /var/adm/inetd.sec and
limit access to FTP daemon on the server.

b) Edit files in /etc/ftpd to tune up the
FTP services:

ftpaccess
ftpusers

c) Enable SU_ROOT_GROUP variable in
/etc/default/security config file and
make users that need to su(1M) to root be
part of that Unix group.

If I had it my way, I would disable FTP and
move to SSH/SFTP.

Likewise, maybe setting RBAC for some users
would help avoid the need to give them su(1M) access to root.

Cheers,

Shalom,

the ftpaccess file is counter intuitive. You add people to it to restrict access.

Also, some ws-ftpd releases had bugs that allowed root access.

I would drop ftp in favor of openssh sftp if possible.

Re: Restrict users access to ftp and make su to root

/etc/ftpd/ftpusers will deny access to ftp users and not allow. You will probably have to create this file. The same goes for /var/adm/inetd.sec. But if you are talking about completely deactivating ftp then you should be doing it in the /etc/inetd.conf file by commenting it out. It can also be done in /etc/services although HP does not recommend this.
