Linux CENTOS - XINETD

Hi,

After some more Linux advice (I will probs be posting 1 a week after my lectures as Linux is confusing me a lot tbh, so bare with me and thank you all so much for the help!)

I need to configure xinetd, from my understanding you configure each service as a new file within the directory /etc/xinetd.d/

I have configured one for ftp, following the example given for telnet (both below) and have changed the configuration on echo-stream (also below) and restarted the service, but service is still failing to work, could I get some pointers in what I have mis-configured

Echo-Stream:

Code:

# This is the configuration for the tcp/stream echo service.

service echo
{
# This is for quick on or off of the service
##############################################
#Only thing edited in this file
###############################################

        disable         = no

# The next attributes are mandatory for all services
        id              = echo-stream
        type            = INTERNAL
        wait            = no
        socket_type     = stream
#    protocol        =  socket type is usually enough

# External services must fill out the following
#    user            =
#    group           =
#    server          =
#    server_args     =

# External services not listed in /etc/services must fill out the next one
#    port            =

# RPC based services must fill out these
#    rpc_version     =
#    rpc_number    =

# Logging options
#    log_type        =
#    log_on_success  =
#    log_on_failure  =

# Networking options
#    flags           =
#    bind            =
#    redirect        =
#    v6only          =
# Access restrictions
#    only_from    =
#    no_access    =
#    access_times    =
#    cps             = 50 10
#    instances    = UNLIMITED
#    per_source    = UNLIMITED
#    max_load        = 0
#    deny_time    = 120
#    mdns            = yes

# Environmental options
#    env             =
#    passenv         =
#    nice            = 0
#    umask           = 022
#    groups          = yes
#    rlimit_as    =
#    rlimit_cpu    =
#    rlimit_data     =
#    rlimit_rss    =
#    rlimit_stack    =

# Banner options. (Banners aren't normally used)
#    banner          =
#    banner_success  =
#    banner_fail     =
}

Telnet:

Code:

  GNU nano 2.0.9               File: 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
        disable         = no
}

VSFTPD:

Code:

  GNU nano 2.0.9               File: vsftpd                                     

# default: on
# description: The telnet server serves telnet sessions; it uses \
#    unencrypted username/password pairs for authentication.
service vsftpd
{
        flags           = REUSE
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/sbin/vsftpd
        log_on_failure  += USERID
        disable         = no
}

Thank you all soo much for your help

And yes I know telnet is insecure but what uni wants it will get

DT.

 

I apologize but why do you push it through xinetd ? VSFPTD has a separate service (/etc/init.d/vsftpd).

Maybe the Arch linux guide will help ? https://wiki.archlinux.org/index.php/Very_Secure_FTP_Daemon#Using_xinetd

 

I have been told to use ftp and telnet through this, im very much a linux noob

 

in the past when I have had xinetd configured correctly, I have not been able to work until I have done the following:

killall -SIGHUP xinetd
service xinetd restart

my service file looks like:

Code:

service livestatus
{
	type		= UNLISTED
	port		= 6557
	socket_type	= stream
	protocol	= tcp
	wait		= no
	cps		= 100 3
	instances	= 500
	per_source	= 250
	flags		= NODELAY
	user		= icinga
	server		= /usr/bin/unixcat
	server_args	= /usr/local/icinga/var/rw/live
#below configure the IP address of the central icinga server
	only_from	= ****IP OF CENTRAL SERVER****
	disable		= no
}

(my file is from a debian build though not redhat/centos)

Are you not needing to specify a port at all?
