hello, linux people

im new here, in the lovely world of linux and im in that stage of learning all the commands of the linux command line of FC4. so the other day i was have fun with the YUM and updated my system, then i rebooted and then i had two FC4 lines and a windows line in the boot loader OF grub. I dont like this, it looks ugly. so i have decide to delete one.. (the older one) but i was wondering by doing this would i be leaving the old version of the (just a guess") kernal behind or some thing else that dosent need to be there.

also, dose anyone know an easy to use FREE firewall for FC4,

..THX

Hey monkey_eater, welcome to linux.

I don't think it would be a good idea to get rid of those lines in grub. See that was a new kernel that YUM downloaded and installed for you. Lets say something goes wrong with one of the kernels and you cant boot into it, you have the other as a backup so you can get into the system and fix whatever is messed up. It may look nasty but in the end you'll be happy you left it there.

As for a firewall, i think ipchains would be your best bet.

You can delete that line in your grub config /boot/grub/grub.conf if you need the old kernel in the future you should be able to selete the boot line on boot up from grub, and press 'e' to edit, then just change it tmp to your old kernel name.

If your running fedora and new to iptable rule sets you can use RH-firewall type 'setup' in a shell and goto configure firewall.

Hello,
by modifying the entries in the /etc/grub.conf, you can assign any name to the "entries" its showing during boot menu option. So choose whatever name you like.

And as NCappaZoo suggested, you should keep that if you would like to be in the safe corner.

otherwise check out the older entries, note them down in some notebook and delete the entries from grub.conf.
in case you get some error with the new one, you can write the older entries back to grub.conf and make that work by doing
#grub-install /dev/hdx

the better solution insteading of copying and deleting would be to comment that entries in the grub.conf itself.

But be handy with either rescue floppy or the live cd ( i.e the bootable cd of the distro )

We don't use ipchains anymore. IPTables is more secure and used by all newer distros by default. Look into Firestarter or Guarddog.

Hello,
Read about Shorewalls and try to configure it.
