I am having problem loading filter rules in my iptables.
I am following this tutorial but am getting this error.
Code:
'ptables-restore v1.3.5: iptables-restore: unable to initializetable 'filter
Error occurred at line: 6
Line#6 says *filter
I am on CentOS and am using iptables 1.3.5
way to monitor traffioc usage by IP address on WHT a while ago.
Well finally I have managed to do it!
Here is what is displays...
PHP Code:
1201K 962M all -- * * 0.0.0.0/0 0.0.0.0/0
54545 41M fws-client1 all -- * * 0.0.0.0/0 192.168.2.6

0 0 fws-client5 all -- * * 192.168.2.22 0.0.0.0/0
I have just one final question....
In the event of a crash, will all the data that has been accumulated using iptables, be lost?
If so is there a way to store the values in a file, say every 5 mins?
I'm getting the following attempts every few minutes, I'd to put a stop to it with Fail2Ban but so far I've been unsuccessful. I get no IP bans in the Fail2Ban panel in Plesk 12.

---------------------- Debug Info -------------------------------
I have a VPS running Plesk 11.x and yesterdady I tried adding a new domain to my subscription and received this error:
Error: Unable to update domain data: Unable to restore the DNS zone: an error occurred while adding the DOMAINNAME IN A DOMAINNAME record: Incorrect DNS record values were specified.
I have one subscription and under that a few domains. I've not had any DNS issues before so I'm a little stumped as to where to start looking. I suspect DNS template issues but I'm not that au fait with the DNS template so I don't want to start fiddling. My service provider suggested I look at [URL] ... which doesn't appear to be related as I have no duplicate domains under my subscription.
Following on from this the VPS is my personal server and I host a few sites for friends consequently I only have the one subscription. I've been advised that I should have one subscription per domain. Is that correct information?
I have Plesk Windows version, when I want import my backup mysql, i see below error:
Error: dbbackup failed: Unable to restore database 'admin_IranDnn'
ERROR 2006 (HY000) at line 1: MySQL server has gone awayClick to expand...
Would like to know what are the dangers of backing up and restoring full entire system backups (with plesk installed) to another server with a different ip address? Will the restored plesk setup operate properly and offer an ip address change in the system, or will there be any pre-requisites required such as manual ip changing within the system core files?
View 1 Replies View RelatedI execute the following commands, in the following order:
iptables --flush
iptables --zero
iptables -A INPUT -s 218.65.12.161 -j DROP
will that last command successfully ban that IP until reboot?
If not, what needs to be done? I can't access my site if I don't flush + zero iptables first but I need to be able to ban with iptables.
I would like to know how to filter more than one NIC with APF firewall... at the moment, it only let you filter Eth0, how do I add Eth1 in it as well?

Is Spam Assassin's version 3.2.x sufficient to block majority of Spam/Junk emails?
As a web host or ISP what do you think is best to do? do spam/virus filtering, or don't touch mail and let the user do what they want with it? (no chance of false positives, or lost mail, this way)
I work for an ISP and we have a barracuda and we get tons of calls from customers regarding lost mail and such as when you're filtering such a large varitey of mail its very hard to have a "perfect" filter. Mail that a car dealership gets and what a hospital get is totally different, for example.
Also in terms of web hosting the filtering will put a reasonable load on the server during peak spamming hours.
So just curious, as a ISP/webhost customer do you think your host should do filter or do you rather manage that yourself?
I sent the below email, it keeps getting caught in the filter

#### Install Notes
We have identified that messages from your IP are being filtered based on the recommendations of the Symantec Brightmail filter as well as our internal Smart Screen Filters. The filter was initiated by Hotmail at (5/20/2009 12:00:00 AM) PST due to a large volume of emails that were sent prior to this time.
We will be happy to work directly with Symantec on your behalf to investigate and possibly resolve this problem. In order to move forward, we will need examples of the messages that were caught by the Brightmail filters.
I am running a small hosting operation and would like to know more about SPAM filtering and controlling. SpamAssasin is installed on my server but it does not do much. I was looking into different solution with a anti-spam device and would like to know which one is recommended the most: sonicwall, barracuda or symantec? (total email addresses is less than at thousand)

I have A/B power from my colo provider, each fed from separate xxxKVA UPSes. I have dual-cord servers powered from these two circuits.
Now I'm adding an EMC SAN, which comes with its own little APC UPS. EMC says the SAN's A-side power should come from my A-side circuit, and the SAN's B-side power should come from the included little APC UPS, which should be plugged into my B-side circuit.
Unfortnately, the little UPS puts out lots of garbage line noise on the upstream side. I know this because I plugged it in at home, and it was turning my X10 light fixtures on and off when the battery would hit a charging cycle. This is not the kind of dirty power I'd like to be feeding to the servers.
Does anyone have a suggestion for cleaning up the harmonic distortion that these UPSes send back upstream? Maybe a Tripp Lite IBAR12/20ULTRA? Or a Tripp Lite IS-1000 Full Isolation Transformer?
Alternatively, if there is a way to tell the EMC SAN to enable write caching without the APC UPS, that might work, too.
How much CPU & RAM load does your spam filter put on your VPS? It seems logical that the more mailboxes hosted, the more VPS resources the spam filter will consume - especially if any of the email addresses are targeted by spammers (or the user is careless and gives out their email address everywhere - as many do).
It's become so much with some of our subscribers that we have had to offer a hardware spam filter, to keep the load off the VPS. It's been great in that the VPS's protected by it have seen a dramatic performance increase....but are these subscribers unique in some way?
And so here is my question...how much CPU is everyone's spam assassin/spam filter using and how many mailboxes do you host on your VPS? very curious...
I am on a DirectAdmin server, with root access. Exim mail server.
Is there any way to filter outgoing messages? Let's say if IP of client is listed in blacklist, they can not send out emails
I have the same problem as many other users who try to send to Hotmail.... my e-mails are being put into the junk filter.
Could you please help me with this as I am going mad trying to figure out how to fix this? I am running a VPS which has 4 IP's and whenever I send an e-mail from the domain it moves into the junk filter. E-mails are received correctly by other e-mail providers (Yahoo, etc.), only Hotmail has the issue.
When I do a DNS Report, the only error I get besides the mail server having a single point of failure, is "Mail server host name in greeting". I have had the VPS provider add a RDNS entry, etc.
I have spoken with the support team at the VPS Host and they have tried everything they could and can't understand why there is an issue. I also contacted Hotmail and they redirected me to a Junk Filter troubleshooting page [url]
I don't know why this is being filtered as Junk and what I can do to fix it. Could you please help as I would be most grateful.
Is someone able to PM me with help as I would prefer not to post the network/website details on the forum please?
Anyone else have problems with Yahoo Spam filters being overzealous? I recently setup a new domain and a few email accounts. After sending a few test messages to my Yahoo email, each one of them was flagged as spam. I changed the text to a more regular email, with no controversial words and still the same result. I notice that Yahoo regularly traps some newsletters I subscribe to in my spam filter, but rarely, if ever legitimate emails. I checked with my web host who informed me they are not on any spam blacklists and that I would have to contact Yahoo. Yahoo's help is quite a maze (designed to make you lose interest and move on), so before I continue hunting for how to contact Y!, I thought I would come here to see if this is a common problem (with a common fix).

I want to filter some keywords showing on the website.
For example,some adult keywords or some force keywords,I want apache change it to * or close the webpage.
I use cPanel/WHM but I find no place to do the setting.
in order to analyse traffic from a specific application I'm using, I need to filter out some types of server requests from the raw log files.
the reason: this app makes multiple requests to the same content in 6 sec intervals.
so I want to leave only the first request, that indicated that this item has been requested, and take out all the others, which can't be counted as hits or visits and just create noise data.
I know how to define a "relevant" request, and how to define a "noisy" request.
the question:
how can I make this filtering?
Do I need to run a script on the log files, clean them, and then use the log analyzer (i'm using Web log explorer)?
Or can i use web log explorer to define a filtering template?
this is a very critical demand, so i'd be glad for any suggestions/ideas how to tackle this problem.
I've been reading about SpamAssassin's Bayes filter. Apparently I need to forward examples of Spam and Ham to a specific email address which SA then checks.
Unfortunately, I do not suspect my average user will do this.
Here's what I'd have in a perfect world: a Webmail program and plugins for Thunderbird/Outlook/Outlook Express that will forward emails to the appropriate place whenever the Junk/Not Junk buttons are pressed. So far, the only one I've been able to find that will do this is Zimbra. However, Zimbra requires an entire server which is overkill for our small company.
I realize Thunderbird already has Bayes filters built in but I would like to do all the spam filtering server-side for consistency.
Is what I want possible?
If not, can anyone link me to a good tutorial for writing Thunderbird extensions?
