I have installed APF on my server (Using DirectAdmin control panel and Exim ). Config below :
This system open incomings ports :
21,22,37,53,80,110,143,443,465,993,995,2222,6000_7000
This system open outbound ports :
21,25,43,80,110,143,443,465,993,995,2222
But i can not send or receive email!
Probably an easy question and I am just not seeing it, but how do you set which email address you want CSF alerts sent to?
View 5 Replies View RelatedDo you recommend a software firewall when behind a hardware firewall?
All of our servers are behind Cisco ASA 5505 firewalls which we rent from Liquidweb. All are being managed correctly and setup to there optimal levels. With hardware firewalls firmly in place, do you still recommend a software firewall such as APF or IPTables (we're talking linux); in our opinion we see it as an extra administration overhead. If this is however untrue, we will change out thinking.
I've found a dedicated server at a great price and plan to stick with it, my first ( already have 2 vps accounts ). I don't have the money for a hardware firewall. However, I do have a chance to renew a Kerio WinRoute Firewall license from way back.
Does anyone think this would be better than the default windows 2003 firewall?
I'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?
I had a email address I deleted on my server (postfix on Debian 4), but to my surprise the server still recieves email for the address!
(I have manually tried sending a email to the address and it comes througt).
I have deleted the address from the /etc/postfix/virtual file and restarted postfix.
What could I have forgotten?
One of my customers asked me if is possible technically to offer free email services.
Since he's going to launch a big portal he want to offer such things later, for all users.
Now, there are problems as:
a) if there is any possibility to compress emails similar with GMAIL or YahooMail or so, because i can't imagine the email is uncompressed
b) how can be handled email boxes over multiple (mail ?) servers if the HDD space needed would be larger than for one server HDD ?
I am having an email issue and I can not resolve. I am hoping for some assisstance here.
One of my local clients are not able to email each other in their office. (About 10 employess I believe)
They are using Outlook mail client, and using ISP's SMTP server. They are able to send/recieve email to other users externally, but not intenally.
Using webmail works perfectly fine.
I spoke with my host and the said everything is working fine. I checked with the ISP to see if they are blocking the IP address on the SMTP server. They said they were not.
I have a personal account on the same server and tried to send email to another local email account, and it did not work either. Tried to send email to my clients email and they did not recieve anything.
I am on the same ISP as my client, so Im still not sure if its the ISP or not.
I setup mail piping with Exim so that e-mails sent to a specific account be forwarded to my PHP script. It's not working properly, because when I send a mail to this account, it's bounced by the mailer daemon:
Code:
This message was created automatically by mail delivery software.
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:
pipe to |/home/user/public_html/support/parse.php
generated by support@mydomain.com
local delivery failed
In my /etc/valiases/domain.com file I have:
Code:
support@mydomain.com: "|/home/user/public_html/support/parse.php"
*: :blackhole:
What can be causing the error?

View 2 Replies View RelatedI'm planning to place some firewalls in my network, but I'm afraid of something.
I have never used cisco pix, checkpoints and others.. We currently use custom made linux solutions for that
When we use these ready-to-go boxes, do we need to NAT the internal server IPs?
Is it possible to use these ready-to-go solutions with REAL IPs in the servers?
Does cPanel work well with NATed internal IPs? Or shall I have some trouble?
Do you think it's safer to with NATed, or it will be better to use real ips instead?
I was wondering what everyone thinks the best Firewall software is for a dedicated server?
View 7 Replies View RelatedIm using the latest cPanel release. Using Pure-FTPD as the ftp server. I have CSF Firewall installed and configured and have also got [url]installed. on the dos deflate software ive set the ban limit to 250 connections.
But what my problem is that while downloading on ftp clients with internet that can download very fast that it will ban them. Ive kinda realised that it is to do with the DDos software but im unsure what i should do. Increase the limit of connections but that would mean that more minor Ddos attacks might get through so that would affect more clients. Or leave the limit at 250 and let clients get blocked for 20 minutes.
Or alternatively is there a way i can stop people getting banned via FTP completly. As i dont see that option on the Ddos or csf.
I´m running the remote desktop service and configuring a remote dedicated server right now.
So, I need to install a firewall in this machine, but I don´t want to be disconnected after the installation.
So, can anyone tell me of a firewall that don´t stop the connection of RDP just after installation and works with Windows 2003 Server?
secure a LAN network with 200 computers, a specific hardware solution (like CISCO PIX or so) might not be available.
Though, I'm considering a Firewall OS based Solution like pfSense, m0n0wall, eBox, Endian Firewall, SmoothWall, etc.
There are so many options and I have no experience with none of this. My Requirements are:
Web based configuration
Clean Interface with graphic statistics
Pretty Secure
Good hardware support
Free usage
Simple configuration
Support for high bandwidth usage
I think OpenBSD is pretty secure, is there any OpenBSD Firewall OS solution with this requirements?

CSF or APF and BFD ?
know of any hardware firewall (or suggest) which is under 300 USD and can protect around 5 servers with a total bandwidth capacity of 100 (+/-) Mbps. I am really no security expert
Of course, it should have web based management, online documentation (not really needed) and something special for prevent DoS attacks automatically (really fed up of them).
If possible if you can link me directly to an online store that can ship it Internationally / Europe?
I was having attacks so I installed CSF firewall which did a great job. However on a few of my sites, specifically proxy ones, every second or third page you visit will be a 403 Forbidden error. After about 20-30 seconds, you can refresh and it goes away. I suspect CSF is causing this, because it just started to happen after I installed it. Is it thinking there are too many connections or too much bandwidth and its blocking me or other users just using the proxy? Is there a way to make it slightly more tolerant?

Lately one of my servers have been getting syn floods and ddos attacks (repeatedly for the last 2 weeks). The attacks are not as bad as they were the last 2 weeks, but my software firewall (iptables and csf) is not doing the job anymore. It can't handle such large attacks.
I picked up a netgear firewall, but it has dhcp and lan, which made it have no use to me. All my servers are on static ips, so I would be unable to use a lan.
Is there a firewall available which would allow me to setup something like this (Server 1 is the one getting attacked):
Internet ---> Firewall ---> 48 Port Switch ---> Server 1, Server 2, and so on
or
Internet ---> 48 Port Switch ---> Firewall ---> Server 1
Other servers come off the Switch
I saw the Cisco Pix on ebay, but am not sure of all the features it holds. I basically need a firewall without any lan capaibilites, no routing, just a plain firewall that will protect from DDoS and Syn Floods (if possible, also email me the logs). Also needs to push up to 20Mbps (100Mbps would be best though).
I looked into m0n0wall and pfsense, but their software didn't make any sense to me. I tried setting it up on a PIII 700Mhz with 768MB Ram but never got the webConfig to work.
Price is not a huge issue, I just need these attacks to end. any suggestions on software firewalls let me know.
