Port 110 Blocked

Nov 16, 2008

They started blocking my Port 25, so I made an iptables entry on my server to redirect posrt 26 to port 25 so I could set my outgoing mail for my server (from Outlook) to port 26. But one day later teh bastards are blocking my port 26 too! Guess they just don't want ANY outbound mail send from anything but their servers! If I had any other option, I'd dump Comcast in a heartbeat!

Did Port 80 Port To 7080, But Not Working When Login

Jun 21, 2009

I 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 ...?

IP Blocked

Jan 20, 2008

All of a sudden my sites are not visible to me hosted in the same cirtex hosting account. I have verified that it wasn't spyware messing with my local computer and can view the site via a proxy. They use cpanel and there is no block visible, but there has to be something somehwere. I told them to restart and that did make the site visible until I checked in the morning, Where would a block be if this is it and is there a chance this was done by a hacker?

Blocked By MSN

Jul 19, 2007

I am blocked by MSN. All email messages directed to any @hotmail.com address is rejected, here a typical message:

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

SMTP error from remote mail server after MAIL FROM:<user@mydomain.com> SIZE=1802:
host mx3.hotmail.com []: 550 Your e-mail was rejected for policy reasons on this gateway. Reasons for rejection may be related to content such as obscene language, graphics, or spam-like characteristics (or) other reputation problems.

I have never spammed nor sent similar content as that listed above.

My host provider says they are contacting MSN for an explantion, but time is running and I need to find a solution to this, because I have some customers (hosted in my server) which need to answer to @hotmailers prospects on their product/services.

IP Not Being Blocked Properly

Jun 28, 2009

I need to block a specific IP:

It adds fine when I do:
iptables -A INPUT -s -j DROP

However, the IP is still accessing files and pages on the site according to Apache:

When I ban other IP's they are blocked from accessing anything on the server (e.g. it wouldn't even reach Apache level because of firewall), but this IP just isn't banning properly.

Recently switched firewalls from APF and CSF, and so far couldn't be happier! But I do have some questions on SYNFLOOD_RATE within CSF.

Currently have a setting for "40/s" and I am still getting many messages in /var/log/messages with *SYNFLOOD Blocked*.

If I enable Synflood checking, the load on the server increases, but the bandwidth usage decreases. But I'm wondering if 'good' visitors are getting turned away?

Is the setting meaning block above 40/s per IP?

Or simply block above 40/s?

Also, does the firewall simply drop the packets above 40?

And is the IP Blocked?

Blocked URLs

May 4, 2008

I'm testing scripts on new server now, and server has 2 problems.

1. I can not enter domain name as "get" parameter. For example, if I'm requesting URL like domain.com/file.php?url=[url] - it does not work. If I'm requesting URL like domain.com/file.php?url=[url](please note it has INVALID extension for TLD) - it works!

2. fsockopen and file_get_contents does not work. I added these settings into php.ini:

allow_url_fopen = On
allow_url_include = On

...and nothing works. I get just blank pages when using these functions.

Server is running cpanel + apache 2.2 + php 5 + APF firewall

IP Blocked By Spamhaus

Aug 12, 2007

I've just got a fully manage VPS, unfortunately the newly aquired IP was listed in PBL (policy Block List)by spamhaus which is a nonspam source. I've got the ip de-listed but apparently some servers are still rejecting emails coming from this IP. It have been almost 48 hrs. Question is:

1) How can the IP got listed when it's never been use? How can we check IP is indeed a 'fresh' or pr-owned by spammers?

2) What is the possibility of the IP being blacklisted by these servers forever? How long does it normally take for it to be totally in the clear?

3) What are the preventive measures that can avoid IP being listed?

4) Is configuring Reverse DNS PTR a standard procedure in server set-up and could missing that config be the main reason the IP got tagged?
