Samba problem with accessing localhost:901

rcj2 · 12-21-2002, 01:03 AM

hello

What would be the cause of getting the error " The connection was refused when attempting to connect to 127.0.0.1:901 " When I try to go to http://localhost:901 I get a failed search on the internet for LOCALHOST. I am trying to connect from the box that has Samba installed.

I am using the xinetd.d and I have the file /etc/xinetd.d./swat, it's not disabeld, and I am running it as root. I have also restarted the daemon and rebooted. No
luck. Samba is also installed on this same box. I am not trying to access it remotely. .

Please help.

what distro are you runnning?

Localhost is a more or less generic term for the loopback network interface on your own local machine. The IP address 127.0.0.1 is the loopback interface and is known by the hostname localhost. Check to be sure your machine hasn't gotten this screwed up. In a shell do "ping localhost" and be sure it successfully pings and resolves the name localhost to 127.0.0.1

Having said that, you won't be able to surf from another machine to the one you're setting up swat/samba on via the localhost name. Localhost always points to the local PC you're typing at. If you're coming from another box to this one, do http://ip_address:901/ where ip_address = the IP Address of the box running Samba, SWAT...

Try it by hand: "telnet localhost 901" to see if you get a connection or a connection refused. If it's refused on the telnet then your browser is telling you the truth and SWAT isn't accepting requests on that port, or at all...

Is SWAT defined to run on port 901?
# grep -i swat /etc/services
swat 901/tcp # Samba Web Administration Tool

Here's my xinetd.d entry for swat:

# default: off
# description: SWAT is the Samba Web Admin Tool. Use swat \
# to configure your Samba server. To use SWAT, \
# connect to port 901 with your favorite web browser.
service swat
{
disable = no
port = 901
socket_type = stream
wait = no
only_from = 127.0.0.1
user = root
server = /usr/sbin/swat
log_on_failure += USERID
}

Looks like it's hard-coded for port 901 here so /etc/services probably doesn't matter. Notice also that for security reasons it's set to only accept requests from the localhost/loopback/127.0.0.1 interface.

Some of the distros, Mandrake for one have a selection at install that pertains to security level

this can really get things wacked, however the place start looking might be /etc/hosts.allow and /etc/hosts.deny

I am running Redhat 7.2.
Let me know what you guys think.

root@localhost xinetd.d]# cat swat

{

port = 901
socket_type = stream

only_from = 127.0.0.1
user = root
server = /usr/sbin/swat
log_on_failure += USERID

try a different browser

you should be getting access denied or a password prompt.

maybe there's something wrong witc /etc/resolv.conf

Does anyone have any other ideas on this?

I'm still stuck.

Thanks for your time.

let's verify /etc/services

Code:

swat           901/tcp

check out swat and make sure it's where it's supposed to be

Code:

root@slacker:~# ldd /usr/sbin/swat
        libdl.so.2 => /lib/libdl.so.2 (0x40024000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40028000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x4003d000)
        libssl.so.0 => /usr/lib/libssl.so.0 (0x4006a000)
        libcrypto.so.0 => /usr/lib/libcrypto.so.0 (0x40118000)
        libpopt.so.0 => /usr/lib/libpopt.so.0 (0x401cf000)
        libc.so.6 => /lib/libc.so.6 (0x401d5000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)


root@slacker:~# file /usr/sbin/swat
/usr/sbin/swat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped



 ls -l /usr/sbin/swat
-rwxr-xr-x    1 root     root      1025883 Nov 20 11:24 /usr/sbin/swat

and check /var/log/messages

Code:

cat /var/log/messages | grep swat

DavidPhillips · 12-24-2002, 12:51 PM

another thing you might try isrun

setup

choose system services
make sure it has swat enabled

maybe if it is disable it save and quit, then go back enable it again

or run

chkconfig swat on

lsterman · 02-03-2003, 12:29 PM

This is evidently a very common problem. In searching for a fix, I have seen hundreds of similar messages describing the inability to use swat because of "connection refused." This also seems to apply to other services accessed through the browser. I have done all of the things suggested on this thread and more, yet nothing seems to work. When using my browser, I am unable to connect to localhost. I'm sure that I'm doing something wrong that is simple or dumb, but I haven't yet figured out what it is.

I have installed Samba and it seems to be working properly. I'm able to access my shares and browse linux computer through a Windows XP machine. I am using the default installation of Redhat 8 as modified to use swat.

Any ideas would be deeply appreciated. I'm just about out of things to try.

RonS · 02-03-2003, 01:22 PM

'chkconfig swat on' worked for me when I had this problem.

lsterman: Ican run SWAT, but cn't browse Linux box from XP Pro. You can browse, but can't run SWAT. Aren't computers grand!

TheTrexx · 02-03-2003, 02:49 PM

Look in /etc/xinetd.d/swat, and look for the line "only_from=127.0.0.1" Erase this line. That's what I did, and I can access SWAT from my Linux PC, and also my other Windows PCs. This is the only solution I can think of.

mawarsha · 02-03-2003, 04:09 PM

I was having the same problem but I ended up reformatting my linux box and after that SWAT worked. If you are behind a router/firewall I would just try typing in 192.168.0.X:901 - that may work.
