i have a customer whos isp blocked both port 110 and 25, so far i was able to fix the problem with sending e-mails (port 25) but i cant see where do i change or add another port for receive email on my server, and since i cant do it... there is no point on opening a port in the firewall.
View 10 RepliesThey 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!
View 3 Replies View RelatedBeen running CSF and very happy with. Just wondering if anyone periodically has to restart CSF because it is blocking something it shouldn't? For example, I have port 5151 open in csf.conf, suddenly (at random) the port will be blocked. I restart CSF and everything is fine.

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.

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?

What has been your experience? Please provide as much detail on your experience as possible.
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:
name@hotmail.com
SMTP error from remote mail server after MAIL FROM:<user@mydomain.com> SIZE=1802:

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.
I need to block a specific IP:
93.6.224.242
It adds fine when I do:
iptables -A INPUT -s 93.6.224.242 -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.
am using APF firewall and am getting ddos from these range ips
4.68.25.*
8.0.4.*
8.0.5.*
how could i delete all the range from these ip's?
I have recently switched to GreenGeeks, great company and great support, but I am having a huge problem that all my clients and I are having problems with. No one can send emails to ATT, Verizon, Earthlink, Comcast, Etc. because they bounce back as being blocked. I have contacted them to unblock the IP and they do, but then a few days pass and it's blocked again. WTH? I've contacted GreenGeeks and they are aware of the problem but I really need to move on with this problem, does anyone know of any solution to do?
Example: ....
We just got a new windows server and didnt put an antivirus or configure windows firewall, while setting up for the 1st two months.
our IP address has been blocked twice now by this company, on saturday, released on monday and blocked again on tuesday.
[url]
we applied to have it removed which they did and blocked it again, they claim we were spamming, which we never did
We have installed mcafee and setup windows firewall.
One of my clients ran an e-mail bomber and gmail is blocking all emails from my server. I've searched but can't find a way to reach google or unblock the IP.

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?
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
I have blocked an IP both in host.deny AND in iptables...and the guy is still able to access my server...any suggestions or something to look for.
CentOS 4.5
I setup php on my IIS in my box and i know i set it up correctly, but each time i reinstall it because of this error i keep getting it.
When i try to see any php file on my IIS through a web browser it shows me some login page no matter what kind of php file it is.
If its html or asp it works fine like here
66.221.255.17
or 66.221.255.17/index.html
but this doesnt work it shows some login
66.221.255.17/index.php and so do all other php files.
My user said he can not view his site from his IP address. His friend from the same ISP also canot access the site.
But i can access from my ISP. So I think probably his IP address has been baned. Therefore, how can I check that? and how can i make his IP range available back?
My IP in clean from any blacklist/RBL databases but hotmail is blocking with the error message below:-

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?
Today a client told he is not able to access the server.
I checked his IP in /var/log/mesages and found 5000 lines of

It seems he is connecting to the server on port 554.
Some of our servers are complaining that they can't access the website. How can we check the blocked IPs using IP tables rules? Are there any special command to check?
