A firewall blocking port 2525?

Jjanel · 09-17-2016, 04:02 AM

Maybe strace -p ..... (on the 2nd PID); also lsof!
Post diff of the 2 config files
Does -second work *IF run ALONE*? data_direcotry *MUST* be different!
*maybe* experiment with using port 225 (instead of 2525 [ms-v-worlds])
(telnet localhost 2525? ifconfig -a to check both ip's...)

harish-mn · 09-17-2016, 06:06 AM

I assigned the port 2525 in master.cf file on both postfix instance
there is two ip address
xx.xx.xx.96
xx.xx.xx.12

first postfix instance (xx.xx.xx.96) working fine
telnet xxxxxxxx.in 25

second postfix instance xx.xx.xx.12 not working
telnet info.xxxxxxxx.in 2525
Trying xx.xx.xx.12...
telnet: connect to address xx.xx.xx.12: Connection refused

here is config file of the both postfix
first one is xx.xx.xx.96
In main.cf file
queue_directory = /var/spool/postfix
myhostname = host.xxxxxxxx.in
mydomain = xxxxxxxx.in
myorigin = $mydomain
inet_interfaces = xxxxxxxx.in
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = xx.xx.xx.96/28, 127.0.0.0/8

In master.cf file
xx.xx.xx.96:2525 inet n - n - - smtpd

second postfix
queue_directory = /var/spool/postfix-xx.xx.xx.12
myhostname = info.xxxxxxxx.in
mydomain = info.xxxxxxxx.in
myorigin = $mydomain
inet_interfaces = info.xxxxxxxx.in
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = xx.xx.xx.12/28, 127.0.0.0/8

In master.cf file
xx.xx.xx.12:2525 inet n - n - - smtpd

postfix status
postfix/postfix-script: the Postfix mail system is running: PID: 958
postfix-xx.xx.xx.12/postfix-script: the Postfix mail system is running: PID: 1027

keefaz · 09-17-2016, 07:43 AM

For inet_interfaces setting, did you try using IP instead of hostname?
mydomain should be domain part of hostname (eg: thinkxxxx.xx)

harish-mn · 09-17-2016, 08:33 AM

i done which u mentioned still facing the same issues
in inet_interfaces setting
inet_interfaces = xx.xx.xx.12
mydomain = xxxxxxxx.in

telnet info.xxxxxxxx.in 2525
Trying xx.xx.xx.12...
telnet: connect to address xx.xx.xx.12: Connection refused

keefaz · 09-17-2016, 09:17 AM

could you post output with

Code:

ifconfig -a

And with:

Code:

iptables -L -v -n

When you start the second postfix instance, you use: postfix -c /path/to/2nd_config_directory?
Permissions for the 2nd_config_directory are ok?

harish-mn · 09-17-2016, 11:50 AM

sorry am not getting

i gave the permissions to the both postfix instance

can you please explain briefly

keefaz · 09-17-2016, 12:08 PM

You have set a directory for the second postfix where you put its configuration files?

Also just wondering, xx.xxx.162.96 and xx.xxx.162.12 are public IPs, no? You own both?
