General :: Iptable Rule To Open Samba Port?
Jun 15, 2010I have samba running on 192.168.100.209 and I am trying to open samba ports only for hosts in 192.168.100.0/24 network.. I have added following rules to iptables. But still I am not able to connect from machines from 192.168.100.0/24 network

I want to open 443. Quote: iptables -A INPUT -p tcp -m tcp --sport 443 -j ACCEPT

Since I'm not at the box, I can't use the nifty GUI.
How might one do this via terminal?

Server :: Open SMTP Port On Router (which Connects LAN To Internet) Also Needs To Open?
Apr 14, 2010I have sendmail running on my centOS 4.6. My lamp server also runs on it. I want to send mail through php mail function. when i execute php page, which fires the mail function, it takes so much long tim1 say even 1 minute, and at last displays that message sent successfully. Suppose, destination address is [URL].... I did not get any mail there. My server is running in LAN. I checked the status of sendmail, it shows me that it ios running. when i issue "nmap localhost" it shows me that SMTP port 25 is open, but when i issue "nmap myserver" (192.168.1.20 myserver ( written in hostfile)), it does not show that SMTP port is open.
I checked the /var/log/maillog, one person in my previous post advice me to see that. There it shows that message is accepted for delivery...but i do not get any mail in my destination, even not in spam folder. One more confusion is that, in my case my server is in LAN and if I am at all enable to open the SMTP port on it, does i need to open SMTP port on my router (which connects my LAN to internet) also needs to open? I think no, because SMTP is application layer protocol, it will wrap my mail in IP packet, which router just need to forward. am i right?

It shows that they are still closed. I am using - [URL] Also yes my ports are open on my router. I know my router works fine with opening ports because I have shoutcast setup on another computer with xp that is currently running. I am willing to pay for who can ever get this fixed for me...
