[url]
i am not able to open it..so i think port is not open so can any one tell me how to open ports...the os installed is centos..
Our new data center provided us with a Cisco ASA5510 firewall. We're setting up all new servers and will begin migrating all of our domains from our current co-lo to the new place.
At the old co-lo, they provided us a very basic BSD based router, and our servers all had external public facing IPs on them. Firewalling was handled at the server (Windows Firewall or Linux IPtables).
The new place is NAT'ing us, so our servers all have a 192.168.10.x address inside, and they map the external address for us through to the inside.
By default, they are locking everything down. I had to ask them to open ssh so I could remote into my CentOS box last night.
I'm not a network guru-- what ports are going to NEED to be opened so I can give them a list? This is a standard PLESK hosting server so http (80), https, ssh, ftp, pop3, smtp, what else? Anyone have a list?
I have used a tool called Net Tools to scan ports on my various servers to determine ports are open in the firewall through my host.
For around a decade, this tool has been accurate to determine what ports are open/closed.
I have used this tool to accurately find issues with the firewall with current host (dedicated server). The network admin says that net tools should not be trusted and even though the software claims the ports are open, they are not open.
I explained that less than a month ago, this software reflected that these ports should closed were reflected accurately as closed by scanning the ports.
Partial results:
Code:
Address Scanned: xx.xx.xx.xx
Scan Started at 10/27/2007 2:08:00 PM
Scan Finished at 10/27/2007 2:18:03 PM
Ports Scanned: 1 To 4000
Total Ports Found Open: 3794
Current Ports Found Open:
Port: 00004
Port: 00005
Port: 00009
Port: 00026
Port: 00044
Port: 00076
Port: 00083
Port: 00088
...
What are the ABSOLUTE best tools/ways that I can confirm that the ports are truly not accessible?
I have just installed APF and it seems to be running great.
I then installed NMAP and did a "nmap -sT -O localhost" but this lists lots of ports that I have shut down in APF and I am thinking it is testing the open ports before the firewall because the list of open ports is the same if the firewall is disabled or running.
Am I doing somthing wrong? Is there another way to test which ports I have open with APF running?
Can anyone recommend a hosting provider (No GoDaddy please) that provides me outbound access to port 3306 and 1221 and is reasonably priced?
I understand that many hosting providers who provide dedicated or virtual servers can give me this option but I only have one website that needs these specifications and that's not worth $60 a month.
I am currently in the throws of configuring a new dedicated "Windows Web Server 2008 / IIS7 / Plesk" server. As part of the setup I have obviously made sure the firewall is correctly setup. After doing this I have run a remote port scan (from my internet connected PC) to the IP address of the server. This has brought up two ports that should be blocked:
5190
1863
I can open a remote telnet session to both these ports, however if I remote desktop to the server and attempt a telnet connection both ports fail to respond.
Does anybody know what these ports are?
If it helps at all, the firewall surrounding the server is an external Cisco device

Do SMTP servers by default use port 25 for receiving mail from another SMTP server? Are there any other receiving ports an SMTP server would be listening on by default?
My question is, a server I will be setting up is going to be behind a firewall that blocks outgoing connections *to* port 25. Is there going to be any way around this that is workable besides opening the port?
i have problem with ports in server
how may i check ports?
for example 37549,53377,17235 and ...
i want know this ports are AVAILABLE or no
i got a new server
spec are:
Intel . 2,4 GHz
80 GB of HDD disk
1GB MB of RAM
Traffic-Unlimited
100Mbit Switch Port
Windows web os
from hosting-ie yes i know the bad reviews but i got my server in 2days
now i saw a good deal that for 12 euros extra get 2 * 100mbit
so i upgraded to a 2 * 100mbit connection as the server would be
used to let members from my forum download music / music videos [remixed] made by me and my other producer so 200mbit server will do nicely for my site
now when i got it it shows me two network connections each saying 100mbit
but only one of the connections is being used and the other is not in use
is there a way that i can use both at the same time or maybe use one for http/ftp and one just for ther server itslef
A potential client asked us the followingo you allow PHP to open sockets on your server? If yes, is there any restriction on the amount of data that can be downloaded?
Will we be able to access and load our remote webpage using PHP? We will use sockets and a Pear library to accomplish this.
We are basically planning on using some content from our remote site on the new site which will be hosted on your servers. Kindly reply back at the earliest.
Is this a potential spammer?
I found out that my server has open DNS. Anyone in the world can query it for domains it is not authoritative for. Is it normal?
View 6 Replies View RelatedI've run "DNS report" test for one hosting in dnsstuff.com and got this warning (as some times before for other hosts:
---------------------
Fail:
Open DNS server
ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address.
-----------------------
Is this anythhing important?
Just being doing a load of DNSstuff.com queries to try and get everything to "pass", I noticed that some big players in the hosting scene have either open or closed DNS servers.
Softlayer.com have closed, while liquidweb.com are open...?
I have changed all mine to closed, just because dnsstuff advises it, but is there any reason you would want them open..?
I have a server that is running linux with WHM/cPanel , some of servers are rejecting mails through server and says that your server is open proxy mail server.
how to check that our server is open proxy or stop open proxy and how can i prevent our server from spammer?
I'm having problems with users using open proxies accessing, abusing, and defacing my website.
I'd like to get a list of all open proxies and incorporate it into my site (i.e. block open proxy accesses)
I've already looked at SORBS, but that is DNS based, and I'm not sure I want to go that route. (I am running one DNS server for my own webserver to use. Don't want to mess with adding another zone for the dnsbl).
I've be much happier building my own php/mysql lookup of the proxy blacklist.
So I'm looking for somewhere I can simply download a proxy blacklist, and update it periodically as needed.
I am using Putty to connect to my server via ssh.

View 2 Replies View RelatedThought this might be of interest to folks on WHT. We put together a solution using Nginx ( Engine-X ) to do Global Server Load Balancing. This solution lets you do GSLB without having to fork over $26k per site to F5 or Foundry.
Thought it would be of interest to both end-users as well as dedicated hosting providers who might want to make it into a service (eg. sell a dedicated host in Europe and the US as a group, with the solution pre-installed).
The entire project, including relavent configs is available for download in the latest ( issue 6 ) FREE issue of o3 magazine (o3magazine.com)

Roundcube can send mails well but horde not. Otherwise since applied the parch i can't get mails from gmail and maybe other providers i don't know yet.
I'm trying to install HyperVM (I know, it isn't great, but need something quick) but need to unblock ports 8888 and 8887. I have no idea on how to do this via SSH. I've looked on Google, but nothing.
If you have a suggestion for another VPS panel which you think is much better than HyperVM and is free, please let me know. I might aswell install that then.
