Aug 5, 2009If I forward port 80 to port 3128 for squid with an iptable rule, does port 3128 have to be open on the firewall or is this all routed behind the firewall?
View 4 Replies View RelatedServer :: 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?
CentOS 5 :: Open Port 7001 But It Doesn't Show That Its Open?
Sep 26, 2010Ok For some reason I open my ports in security and firewall. I open ssh and other ports and port 7001 for example but when I go to check to see if they are open or try to connect to them. 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...
I open the ports in graphical mode.
Ubuntu Networking :: Error - Remote Port Forwarding Failed For Listen Port 5500
Aug 7, 2010When I use the following command:
ssh user@ssh_server -L 5500:localhost:5500 -p 22
everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:
ssh user@ssh_server -R 5500:localhost:5500 -p 22
I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...
General :: How To Open A Port
Jul 23, 2010I hear that it's a bad idea to edit iptables by hand.
I want to open 443. Quote: iptables -A INPUT -p tcp -m tcp --sport 443 -j ACCEPT
iptables -A OUTPUT -p tcp -m tcp --dport 443 -j ACCEPT
Since I'm not at the box, I can't use the nifty GUI.
How might one do this via terminal?

May 23, 2010I just installed apache. I didn't change the configuration files at all except add Quote: # added servername to avoid the could not determine fqdn error ServerName myname.homelinux.org to apache2.conf. Apache is working locally (I get the `it's working' screen at [URL]). However, I cannot access my computer from an external computer by going to [URL], which is equivalent to [URL] -- [IP address changed slightly for privacy] Here is a screenshot to my router settings. I disabled the filter for port 80 on the router. here shouldn't be a firewall, unless it's automatically installed with ubuntu 10.4. (sudo ufw status says `inactive'.)
I checked my ports from [URL] and indeed port 22 is open (ssh-ing into my computer externally is not a problem), whereas port 80 is closed. What step in opening up port 80 am I missing? (I also made sure my ISP isn't blocking port 80.)

Servers :: Can I Open Port On Ubuntu 9
Oct 11, 2010I can seem to open port 25565 for a java application (executable jar)
I'm running ubuntu server 9 thoroughly up to date code...
Yet connections to port 25565 fail when I have the firewall enabled (sudo ufw enable)
For example canyouseeme.org says "Error: I could not see your service on port (25565) Reason: Connection timed out"
And connections to port 25565 _DO WORK_ when I disable the firewall (sudo ufw disable)
canyouseeme.org says "Success: I can see your service on port (25565)"
Networking :: Testing If A Particular Port Is Open ?
Jun 17, 2010I would like to test myself if port 5060 is open for UDP packets.
I got a few shell accounts outside of my ISP that run Linux or different BSDs. Does someone know a common program where I could send UDP packets to port 5060 of the IP address that Virginmedia assigns to me and then I would need a program on a PC within my network who reads them _if_ they get through.
Background of all this is that my VOIP phones from two different VOIP providers are offline since last Monday.
One service provider confirmed that another VOIP client is online with the same service provider Virginmedia but in a different area.
So, while I don't know how long does it take that someone from Virginmedia can tell me if their port 5060 is open for UDP, I would like to find out myself in the meantime.

General :: Localhost Port 25 Not Open ?
Nov 6, 2010Made some network and hardware changes, and now I can't get the mailserver to work. It seems that sendmail can't loop to itself on 127.0.0.1. When I nmap localhost, I find that port 25 isn't open.
Naturally, nothing has changed on my system except for different routing, interfaces, etc.
So the question for sendmail gurus,is where should I be looking?
