Default fail to telnet localhost 106
Hi folks,


Ubuntu 7.04 server amd64


On running;

$ telnet localhost 106
Code:
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
$ netstat -an | grep 106
$ sudo netstat -an | grep 106
both no printout


Pls advise where shall I check and how to fix the problem. TIA


P.S.
1)
confirmed with ISP port 106 is open

2)
I'm adding "change password" plugin on SquirrelMail. After installing poppassd on repo I tested it whether works according to /usr/local/squirrelmail/www/plugins/change_pass/INSTALL
Code:
Be sure to test and make certain your poppass daemon is working properly.
To test, try telneting into the daemon and changing a password:

$ telnet localhost 106
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
200 poppassd v1.8.1 hello, who are you?
user <username>
200 Your password please.
pass <oldpassword>
200 Your new password please.
newpass <newpassword>
200 Password changed, thank-you.
quit
200 Bye.

Default output of netstat -tulpn?
Can you paste output of the following command?
Code:
sudo netstat -tulpn
Are you sure all mail server related services are running? If not start service /etc/init.d/openbsd-inetd service to open port 106:
Code:
sudo /etc/init.d/openbsd-inetd restart
Make sure Iptables is not blocking access:
Code:
sudo iptables -L -n
Try out and let me know

Do you have poppassd installed? I don't think so:
Code:
sudo apt-get install poppassd openbsd-inetd
sudo /etc/init.d/openbsd-inetd restart
Make sure you open port 106

Thanks for your advice.


Something I can't understand;

$ locate poppassd
Code:
/etc/pam.d/poppassd
/etc/xinetd.d/poppassd
/usr/sbin/poppassd
/usr/share/doc/poppassd
/usr/share/doc/poppassd/changelog.Debian.gz
/usr/share/doc/poppassd/copyright
/usr/share/doc/poppassd/README.gz
/usr/share/man/man8/poppassd.8.gz
/var/cache/apt/archives/poppassd_1.8.5-3.1ubuntu1_amd64.deb
/var/lib/dpkg/info/poppassd.conffiles
/var/lib/dpkg/info/poppassd.list
/var/lib/dpkg/info/poppassd.md5sums
/var/lib/dpkg/info/poppassd.postinst
/var/lib/dpkg/info/poppassd.postrm
$ locate tcpd
Code:
/usr/sbin/couriertcpd
/usr/sbin/tcpdump
/usr/share/doc/tcpdump
/usr/share/doc/tcpdump/changelog.Debian.gz
/usr/share/doc/tcpdump/changelog.gz
/usr/share/doc/tcpdump/copyright

/var/cache/apt/archives/tcpdump_3.9.5-2ubuntu1_amd64.deb
/var/lib/dpkg/info/tcpdump.list
/var/lib/dpkg/info/tcpdump.md5sums
both poppassd and tcpd are there.


However running;
$ apt-cache policy poppassd
Code:
poppassd:
  Installed: (none)
  Candidate: 1.8.5-3.1ubuntu1
  Version table:
     1.8.5-3.1ubuntu1 0
        500 http://us.archive.ubuntu.com feisty/universe Packages
        100 /var/lib/dpkg/status
$ apt-cache policy openbsd-inetd
Code:
openbsd-inetd:
  Installed: (none)
  Candidate: 0.20050402-3
  Version table:
     0.20050402-3 0
        500 http://us.archive.ubuntu.com feisty/main Packages
They are not installed yet.

Do I need to remove them before running;
Code:
sudo apt-get install poppassd openbsd-inetd
sudo /etc/init.d/openbsd-inetd restart
???

Thanks


$ sudo netstat -tulpn | grep 106

port 106 is open

Hmm not sure, it looks like port is open now. Can you just stop firewall and try it again?

To stop iptables you need to provide few more commands:
Code:
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
After all of the above, it should work.

Performed following steps;

$ sudo iptables -F

$ sudo iptables -X
$ sudo iptables -t nat -F
$ sudo iptables -t nat -X
$ sudo iptables -t mangle -F
$ sudo iptables -t mangle -X
$ sudo iptables -P INPUT ACCEPT
$ sudo iptables -P FORWARD ACCEPT
$ sudo iptables -P OUTPUT ACCEPT
all without complaint


$ telnet localhost 106

Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
Connection closed by foreign host.
$ telnet 192.168.0.10 106
Code:

Still the same.
