how to change priority of telnet session

how to change priority of telnet session

[gshan]

Hi All,

I'm using telnetd which was started by xinetd. The current default 
priority of telnetd isn't high enough,
so I want to increase it by conf files. Do you know how to increase 
telnet or telnetd's priority through
changing conf files?

root@(none):/etc/xinetd.d# cat telnet
# default: on
# description: The telnet server serves telnet sessions; it uses \
#       unencrypted username/password pairs for authentication.
service telnet
{
        flags           = REUSE
        socket_type     = stream       
        wait            = no
        user            = root
        server          = /usr/sbin/in.telnetd
        log_on_failure  += USERID
}

Thanks,
Gavin

1) That's not a kernel issue, that's a userspace configuration issue, probably
best asked on a mailing list for administration of whatever distribution of
Linux you're using.

2) There's a fairly high likelyhood that your real problem isn't that telnet's
priority is too low, because telnet is a fairly lightweight process and *should*
behave fairly well unless there's major system tuning issues - and if that's
the case, there's probably *better* ways to fix the problem.  What problem are
you trying to solve by changing telnet's priority?

I think so, but I don't know what's the mail alias. I finally solved
the problem already: "nice" option could be used in telnetd config
file to increase its priority.

Sorry, I should have described the issue I have clearly enough: I
want to change priority of telnetd instead of telnet. The telnetd session
is now started by xinetd with config file /etc/xinetd.d/telnet.
