Q. How do I install and start telnet service / server under Ubuntu Linux?
A. Telnet is an insecure service. It is recommended that you use ssh service. However sometime telnet server or service is needed. Here are instructions to enable telnet:
Install telnetd server
$ sudo apt-get install telnetd
Restart inetd service:
$ sudo /etc/init.d/openbsd-inetd restart
You should now be able to telnet to the server from Windows or Linux desktop system to Ubentu Linux telnet server. Type the following command to connect to Telnet server:
$ telnet ubentu-linux-server-ip
$ telnet 192.168.1.200
$ telnet ubentu.mydomain.com
Q. After windows XP installation I lost my Grub boot loader and now when I try to run grub-install command to restore Grub in master boot record. But I am getting an error that read as follows:
/dev/sda does not have any corresponding BIOS drive
How do I fix this problem?
A. grub-install is use to install GRUB on your drive. If you are getting error try to recheck device map.
Type the command as follows:
# grub-install --recheck /dev/sdaWhere,
- –recheck: Probe a device map even if it already exists
- /dev/sda : Replace /dev/sda with your actual device name.
Above command should fix the problem.
