Ip_conntrack Wont Work?

Jun 17, 2009

I've got the latest grsec stable, but i'm having a problem with getting ip_conntrack working.

I did the following with make menuconfig after copying my default kernels config file...

Networking -> Networking support -> Networking options -> Network packet filtering
framework (Netfilter) -> Core Netfilter -> Configuration -> Netfilter Xtables support
(required for ip_tables) -> "conntrack" connection tracking match support.

After a compile and reboot:

error: "net.ipv4.netfilter.ip_conntrack_generic_timeout" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_icmp_timeout" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_close" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_last_ack" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_established" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_recv" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_sent" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_udp_timeout" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_udp_timeout_stream" is an unknown key
error: "net.ipv4.netfilter.ip_conntrack_max" is an unknown key
error: "net.ipv4.ip_conntrack_max" is an unknown key

I did a ls on /lib/modules/2.6.27.10-grsec/kernel/net/ipv4/netfilter and dont see the modules that i see in the default kernels...

Ip_conntrack: Table Full, Dropping Packet

Mar 20, 2008

ip_conntrack: table full, dropping packet

What does that error mean? It's related to iptables right? When I do this cat /proc/sys/net/ipv4/ip_conntrack_max, I get

65536

I increased it

131072

Because someone recommended me this number because I have 4gb of RAM. But I still get the table full errors or

host kernel: printk: 500 messages suppressed

What should I do? Should I keep increasing the number? How do I know how much I can increase it by?

CGI, SSI Won't Work

May 29, 2009

I'm having exec cgi issues,

CentOS 5.3 x86_64, Linux, Apache/2.0.63,
cPanel 11.24.4-R36167 - WHM 11.24.2 - X 3.9

Error is,
[an error occurred while processing this directive]

If I "uncheck" IncludesNOEXEC in Apache Global Configuration the error disappears, but the SSI doesn't work. If I check it the error is there, but the SSI works.

Here's what I have done so far,

Through WHM,
Main >> Service Configuration >> Apache Configuration,
Pre Main Include, Pre VirtualHost Include, Post VirtualHost Include,
I added,
Options +Includes
AddType text/html .htm
AddType text/html .html
AddOutputFilter INCLUDES .htm
AddOutputFilter INCLUDES .html

Options +ExecCGI
AddHandler cgi-script .cgi .pl

I also added this to the httpd.conf
<Directory "/">
Options +ExecCGI FollowSymLinks Includes IncludesNOEXEC Indexes -MultiViews SymLinksIfOwnerMatch
AllowOverride All
</Directory>

Options +ExecCGI
AddHandler cgi-script .cgi .pl

Then I tried,
Options +ExecCGI
AddHandler cgi-script .cgi .pl
in the .htaccess file

FTP Will Not Work

Aug 29, 2007

After spending nearly 4 days trying to get ftp working on my server i still haven't achieved it. I got a server with a default install of plesk and cent os 4. I update to 8.2 and when i first go to try ftp it says "server closed connection" on my ftp client.

So then i tried updating 8.2 again and the installer failed. So i tried manually installing both proftpd and pureftpd via ssh and yum and it fails to install. I've also restarted the server a few times. I've tried logging in with every single username/domain/i.p. assigned to the server. and i've had no luck.

SSH, How Does It Work

Mar 5, 2007

how does SSH work and really what is it.

This is my knowledge, I may be wrong or right:

There are two ways of controlling your server, through control panel and through SSH, now SSH is where you type in codes to control your server.

Now from what I know you can't login to SSH alot due to security reasons.

I was wondering, if I have a forum can I login to SSH everyday to back up the database?

Why Iptables Not Work

May 28, 2009

My site is under DDOS attack. I run this command

netstat -an | grep :80 | grep ffff | awk '{print $5}' | cut -f 4 -d : | sort | uniq -c | sort -n | tail -10

And find a lot of IP that are attacking. After that, i run

iptables -A INPUT -s xxx -j DROP

to block IP, and

service iptables save

service iptables restart

But when i run netstat command abouve, i found IP are attacking still available, it seem iptables don't block it?

How Does Reverse DNS Work

Jul 22, 2009

some clarification with regards to Reverse DNS.

An example ip: xx.xxx.xxx.xx is owned by A Company via a DC. The they have their name allocated to the netname and description when i look up their ip address.

I have my ip xx.xxx.xxx.xx this is me and it currently contains my DC's name throughout when i look it up as the description and netname...

Both are from the same DC however the other company has their name allocated to the ip address and i would like to do the same. Does this require Reverse DNS? It dosent involve domains surely does it?

Php-cgi Isn't Work With Mod_rewrite

Oct 28, 2009

I have been using apache and php-cgi and it works well together but when I tried to use
mod_rewrite it stopped working and I got "Internal Server Error" result.

Apache error log showed "FastCGI: incomplete headers (0 bytes) received from server"

I think that mod_rewrite rules are ok because when I refer to some HTML file then it all works.

Apache 2.2.14 and php 5.2.11

VPS For CPU-intensive Work

Jul 14, 2008

I'm working on a new project that involves some heavy data processing in the preparation stage. As an example, one of the setup jobs is now running on a P4-3.0HT desktop at 100% CPU and I estimate it'll be finished in just under a week! Memory and i/o usage are minimal but it's extremely CPU-hungry.

There are other similar jobs to follow and some correlation between the number of cpu cycles and the quality of results so I foresee an ongoing need for computing power for at least a few months.

Viable options are to continue running my own hardware (probably supplementing the P4 with something a bit newer), Amazon EC2 or a cheap dedicated server - I can get a good handle on the cost and performance of each of these.

But I wonder if I'd get more bang per buck from a few VPSs? Some of the VPS benchmark results are spectacular so I suspect the answer could be yes, in the short term anyway. But I don't want to hog the host-node's CPU to the point where it degrades other users' performance or gets my account shut down... Then again, judging by the performance of the VPSs I've used for hosting the node seems to have a lot of spare CPU available...

So (finally) to the questions: Am I crazy to even consider this? If not, which technology would be most suitable? (I'm thinking Xen because of its reputation for better isolation.) Has anyone else done anything similar?

Site Www Does Not Work But Without Www Does

Jun 1, 2008

Like the title says, I just moved my site over to my own server, and it is running cpanel. Anyways the main site [url]works, but [url]does not.

What is really strange is, [url]works fine as does [url]

So I figure there is something I have to do to get it all to work right.

The other issue is that if you are logged into [url]but goto [url], you are not logged in anymore, but if you go back to the original link, then you are still logged in. This happened on the other guys server before with the main site as well.

Lighttpd Not Work Well With Php

Nov 9, 2007

Lighttpd works well with static file.

But for php, it's totally not good for me
I just install lighttpd and php.

By [url]

Now It takes about 10 seconds for the
server to response.

Here is a part of config file
############ Options you really have to take care of
####################
server.max-keep-alive-requests = 4
server.max-keep-alive-idle = 4
server.max-read-idle = 60
server.max-write-idle = 1024
server.max-fds = 8192

php.ini using the default one
Here is the link to it

And only about 200 connections. the load average is only 0.02.

When I check the error log

Www. Doesn't Work

Aug 2, 2007

today I noticed that whenever I type any of the domain names on my server with a "www." in the address bar, it simply says "server not found". When I remove the "www.", it loads the site?

This is a major issue. It never used to be this way, but I noticed it today. Where should I edit? Could it be "named.conf"? Or maybe just DNS cname settings in plesk?

How Does Colo Work

Apr 19, 2007

You rent space at a datacenter that fits your power and cooling requirements. You bring your own equipment or ship it to the datacenter to get setup in your rack. Who handles fixing things? You or the datacenter? Also, do you ever have access to your server physically while it's at a datacenter?

How about bandwidth and providers? NOCS, POPS, IAX's etc... Where do those come into play and how does that structure typically look (anyone have any graphical illustrations of how peering/backbones etc work with IAX's, POP's, and NOC's?) I'm curious more about that then colocation at it's most basic forms.
