CentOS 5 Server :: Method Of Seeing Real-Time Traffic / IP To Apache

Sep 16, 2010

We have a production web site running apache 2.2.3 across several web servers. we also have a major problem with SPAM comments right now. our method of identifying valid IPs (whether by external clients/customers, or internal personnel) vs SPAM'ers is not ideal - its prone to erroneously labeling legit IP's as targets to be blacklisted.

What we need is.. a way to see how much distinct request traffic is coming from any given IP address to the site in real time (or very near realtime). Essentially we want to see in some graphic/chart way requests per sec to apache / per ip sorted by requests per sec.Would nTop do this? I've only used this in a limited form at a branch office, not on a production web server.

CentOS 5 Server :: Time On Xen VM's Drifting Ahead Of Real Time?

Aug 4, 2009

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

Networking :: Real Time Traffic Counter

Jul 6, 2010

I have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections). So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know).

Software :: Visual Real-time Traffic Monitor

Dec 26, 2008

Does anyone maybe know of a client app for Windows/Linux that polls the Linux (Ubuntu) Gateway and checks (in almost real-time) what the bandwidth usage is? Something like KInternet (which is SuSE only as far as I know) where you can see a graph showing how much kbps is sent and received per second.

CentOS 5 :: Real-time File Replication For User Accounts?

Nov 22, 2009

this idea to me right now seems stupid and impractical so I'm also looking for solutions outside of this one. I'm creating a set of highly available servers. They currently utilize pacemaker to manage a shared IP address, apache management, mysql management and also drbd handling. They currently replicate, properly failover and run fine. However, this is a shared web hosting setup and everytime a new user is added to the system a username and password is created and the httpd.conf file is updated for their site. I need a way to replicate those changes to the other server. For httpd.conf I'm pretty sure I can just stick it on the apache drbd resource and create a symbolic link. However, for the passwd and shadow files that is not a realistic solution.

Server :: Is It Possible To Sync In Real Time Over Ftp?

Feb 1, 2010

I am currently using curlftps to mount a directory on a ftp server locally as /backup , I then use rsync to do an incremental backup to this directory every night and a full backup at the weekend.A requirement has arose for a similar set up but one that syncs in real time, so if a user puts a file in a directory it immediately copies that file to my ftp server, in this case it immediately copies it to /backup

General :: Check Server Bandwidth Usage In Real Time?

Mar 21, 2010

I'm trying to check my server's bandwidth usage in real time, installed the following programs but none worked so far.

Iptraf - No results even when using iptraf -u
Tcptrack - Error : pcap_loop: cooked-mode frame doesn't have room for sll header
Iftop - No results, everything 0b

Are there any programs that displays bandwidth usage in real time and actually works on VPSes? Or getting real time bandwidth usage on a VPS is simply impossible?

Server :: Switching From Openssl To Gnutls For Https Traffic On Apache

Nov 3, 2010

For some years now I have been able to use openssl (apache-mod_ssl) to process encrypted traffic because I had, in effect, only one host - the main server - as the sole entry in our ssl_vhost.conf file.

Now we are working toward serving a couple of more secure sites for closely related organizations, but with their own distinct identities. This, in the past, would have meant additional static IPs with matching nic cards for starters. But my understanding is that since 2007/8 we have been able to use gnutls (apache-mod_gnutls) which gets around the old problem of Apache not being able to direct name-based traffic because that would not yet have been decoded. This is referred to as SNI - Server Name Indication.

Here my confusion begins. Is there an overlap between SSL and TLS? For instance, I would have generated RSA keys and a self-signed certificate with the genrsa command. Is this sufficient for gnutls or does it need to generate its own keys and certificates? I realize gnutls is relatively a new kid on the block but it is appealing and I'd like to give it a try.

I am working with the Mandriva/Mageia cooker with an x86_64 architecture so all packages are up-to-the-minute.

Server :: PPTP Traffic - Gre Traffic Is Being Generated During The Browsing / Reduce Traffic

Sep 27, 2009

Recently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:

Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT

iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.

When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.

So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?

Software :: Convert Unix Time To 'real' Time

Jan 28, 2010

I used the following command to get the unix time of root user creation:

Code:
awk -F":" '$1 == "root" {print $3}' /etc/shadow
How can i convert this into the date/time of creation?

I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..

Should I use iptables to set up nat or the route command or what? I just want to know the group of tools to use in order to set up my network. Network diagram: Internet <------> Debian Box <----> switch <----> hosts I found some guides but they are for linux 2.4 and i'm not sure if they are right.

CentOS 5 Server :: Gateway Server To Redirect Traffic For Http/smpt/pop3

Apr 6, 2010

I have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).

I need a gateway to direct web traffic to three separate servers/domains. I have been trying to do this with both a dns server and , (seperatly), apache server to forward requests. The dns server was a no go, and <i can only get apache to redirect http and ftp.

After Googling this ALOT, I believe that what I need is a gateway server to redirect my traffic to the 3 different servers. I have been reading about using using nat and iptables for this and was wondering if anyone had any advice/suggestions on this. The other thought I had was to use something like pfSense to create the gateway, but I am still reading the documentation, and I am unsure if this approach will work.

Server :: Apache Simultaneous Requests Time Out While PHP Script Is Running?

Apr 1, 2011

On my server I provide OCR file conversion service but the problem is when a user uploads a file and it's being converted then if you open another tab and try to load the site it won't respond until that conversion is completed. In other words until the PHP script finishes execution apace doesn't serve any other request to the same browser.

Here is my apache configuration:

Code:

ServerTokens OS
ServerRoot "/etc/httpd"
PidFile run/httpd.pid

[code]....

You can check what I mean if you try to upload and convert a file and while the file is converting try opening the site in another tab.

CentOS 5 :: Apache Error 403 - "Forbidden You Don't Have Permission To Access /bb/ On This Server" - 5.2 With Apache 2.2.3

Jan 20, 2011

I am installing Big Brother on a CentOS 5.2 running the default Apache 2.2.3. When I try to access any web page I get the following error: Forbidden You don't have permission to access /bb/ on this server. Apache/2.2.3 (CentOS) Server at fmsubbnix Port 80 So far I have:

1) Set the Directory options to FollowSymLinks
2) Verified all directory and file permissions are at 755
3) Set permissions temporarily to 777 and received same error so I am assuming the issue is in a config file somewhere
4) in hhtpd.conf verified <Files ~ "^.ht"> is correct
5) verified the "default" directory is correct (/var/www/html)

I have read and tried several ideas in posts listed on the web but to no avail and am at a loss as to what to look for next..
