I am managing a server and just learning how to do everything. It is a linux server running WHM/Cpanel. I need web scripts on this server to be able to connect to external SMTP servers. Therefore I need to open up port 25 (if it is not already).
How do I open ports on my server? Hopefully by using WHM/Cpanel (I am not too familiar with using the command line).
I have a VPS running CentOS 4.4 which I have just been securing. It is running apache on port 80, BIND on port 53 and ssh on an atypical port. However, when I do a portscan with nmap I find that port 5190/tcp is open. There is no daemon listening on the port (I think it is for AIM?) and in any case iptables should refuse any connection on this port. Should I worry about this or is the port pretty safe to leave open?

If it is not open how do I open the port ?
It is a CentOS server with no Control Panel
Due to some circumstances out of my control, I've had to move from postfix to qmail. In postfix, I simply edited master.cf and added a new line to open it up on port 26 and 25 at the same time. In qmail it's not that easy. I followed the instructions at http://www.daniweb.com/forums/post256079-2.html and it worked, but it takes about 15 seconds for thunderbird send the mail (it sits there saying 'connected to mail.domain.com)
Is there a better way of opening qmail on 26 or forwarding requests for 26 to 25?
I want to check if certain port is open and not blocked by my ISP how can I do that?

View 1 Replies View RelatedI have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?
about the NIC and switch,
there are giga port vs mega port,
in your experience,do they really be different?
I recently changed my SSH port, but locked myself out when my APF firewall was installed.
Where would I got to add a custom port inside the APF's config file?
Is there a way to exploit openssl? someone came to me asking me for a job on hostparlor.com and i said no. They then uploaded a remote view script to exploit perl and gain access. I patched that. Then he again said that he can exploit through openssl. I thaught open ssl was security itself? He then told me that he can gain access through php sites to root? Is that possible? We have phpsafemode set to off because we run whmcs and it requires it to be off. He said he can hack us through that aswell. Is this guy just bluffing or can this seriously be done? Like i said this is why i have 2 server admins...

Any help is very much appreciated.
i would be interested in knowing like what would you prefer for your dedicated server? i.e Behind a firewall or on public network. Can anyone experienced provide pros and cons on this one?
View 4 Replies View RelatedI bought two Dell R200 because they was extremely cheap.
My target is Open Source SAN with active/passive setup.
Now i was wondering what RAID-level I should go for.
I will use 1TB SATA-II disks.
1) RAID-1 in both servers and mirror each other with DRBD.
With this setup i have like double RAID-1 so i lose lots of disk space.
4 disks -> 1TB
2) No-raid at all and i will mirror data with DRBD.
4 disks -> 2TB
Then there is change to go for RAID-5. Theres enough space to put third disk in that case
3) RAID-5 in both servers. Mirrors data with DRBD.
6 disks -> 2TB but more performance.
But in every setup i lose space more then i would like to.
Actually i dont need space more then 1TB, but i would like to get best possible redundancy and most space available i could.
Also need to remember that those servers does not support hot-plug HDs so in case there is disk-failure i need to be able to shutdown one server and iSCSI should still be up and running.
Of course theres change to make it active/active.
I was thinking that if I go for the RAID-5 I will make LVM-VG on both nodes (san-vg1 and san-vg2) and use it 50/50.
In case of fail both VG's will be used from working node.
Im going to use Debian Lenny I guess..
I was looking for OpenFiler because of the GUI, but im familiar with Debian and have always done everything from cmd.
me and my customers are problems to open, FTP.
i was restarted FTP server, but i have problem to load FTP with (IE, CuteFTP, other programs...).
i using, cPanel.
i have to get rid of an open relay state on my server, and i cant do it! i have antirelayd on my WHM but it seems its not working, any idea? please or at least wich line in /scripts/antirelayd i have to check to see if its everything ok.
i saw an older post, tried everything but nothing works x_X
I've tried everything under the sun to try and close the open dns server issiue on my box but nothing seems to fix it.
Here' what my named.conf looks like...
----------------
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndckey"; };
};
acl "trusted" {
1.2.3.4; 2.3.4.5; 127.0.0.1;
};
options {
directory "/var/named/";
allow-transfer { IP's that are allowed (slaves/master);
// query-source address * port 53;
version "not currently available";
allow-recursion { trusted; };
allow-notify { trusted; };
allow-transfer { trusted; };
};
-----------------
an A/V kind of solution, that allows me to use my own custom signatures, etc. just wondered if such a thing existed.
View 2 Replies View RelatedI created a (dv) account with Media Temple and my starting domain name becomes my name servers... Now they setup on there DNS server a reverse lookup for mydomain.com, but not for any of the domain names which go under it.
They won't setup a reverse lookup for any of your sub domains, unless they have a dedicated IP address, which costs $1.00 per month per IP address.
So what this means is say one of your sub-domains sends an email to myclient.com and it so happens that myclient.com like many other domains does a reverse lookup on incoming emails to verify its not spam, but since the reverse lookup doesn't exist, your sub domain gets an error message saying the email can't be delivered.
I emailed them and there first response was ....
I am looking for a opensource ftp client so I don't have to license a million computers with it. Any body have any good ones they can list?
