It depends on what you actually mean by this question. I assume you want to
telnet into a remote server and upgrade its kernel. The steps are:
1. Get the kernel source (or executable, if you're trying to get a
pre-compiled kernel) onto the server. You can do this via a remote telnet
connection to the server, but it will need to make an ftp (or http, such as
by way of wget) connection to someplace that has the kernel source (or
executable) packaged in a uitable form (a .tgz, an .rpm, a .deb, or
whatever) for your Linux distribution to work with.
2. Compile the new kernel from source, if you're using source.
3. Install the compiled kernel and run LILO (or grub, or whatever boot
manager you are using) so it will boot the new kernel.
4. Reboot the host.
All of these steps *can* be done via telnet. I've done them all via ssh,
many times. The downsides of using telnet here are:
A. The usual security problems with using an unencrypted connection,
especially important here because a lot of this work needs to be done as root.
B. If the host is physically remote and something goes wrong, you do not
have ready local access as a fallback.
While I've done this often, it's always been for servers that were onsite,
so when (occasionally) something went wrong, I could reboot the system and
access its console to fix things.
