hi users How can I restrict users to login from particular IP range ? Is it possible to implement this in TELNET ? I have one more server where sendmail is able to send but unable to recieve mails. return mail says that it is unable to find the host. And maillog says BROKEN PIPE. What is the meaning and how can I rectify this two problems?
