Simpleish PHP/flat Files - Create File, Edit, Save
Nov 24, 2007
Display some text in a web browser from a file called text.txt
text.txt will have many lines and some of them I do not want users to be able to modify and overwrite.
config_item_1=user can edit
config_item_2=user should see but not edit (could be on any line)
config_item_3=user can edit
config_item_4=user can edit
The user has made their changes in the web browser and clicks submit. I then need this info to be saved as the text.txt file however some checking needs to be done first. Anything matching config_item_2 should be removed. This could be on any line. Anything not matching should be permitted and added.

i use the following perl script(created by me) to save server load every 30 minutes to a log file i just keep it running in the background(probably would be more effective using cron)
#!/usr/bin/perl
while(1) {
$w = `w`;
#print $w;
$w =~ /load average: (.+)
/;
$log = $1;
my ($sec, $min, $hour, $mday, $mon, $year) = localtime;
my $rightnow = sprintf("%04d-%02d-%02d %02d:%02d:%02d ", $year + 1900, $mon + 1, $mday, $hour, $min, $sec);
$log = $rightnow . ": " . $log ."
";
open (OUTFILE, ">>top_logfile.txt");
print OUTFILE "$log
";
close (OUTFILE);
#sleep for 30 minutes
sleep(1800);
}

Command: CWD /public_html
Response: 550 Can't change directory to /public_html: Permission denied
Error: Failed to retrieve directory listing
That's what I see in FTP, but in File Manager in cPanel I don't see any files.
What do I do?
The permissions is set to 750 for /public_html and I cannot change them

I see in the maillogs a number of errors lots of different Certificate Authorities - and some I really did NOT expect to see here:
[root@web48002 admin]# grep ' certificate verification failed for' /usr/local/psa/var/log/maillog | wc -l
998
[root@web48002 admin]# grep ' certificate verification failed for' /usr/local/psa/var/log/maillog | head

[Code] ....
How/where do we edit our CA file under Postfix - and why is the standard one installed by PPA not including some of these VERY MAJOR CAs?!?
I would like instructions on how to edit this in a manner that it will not get overwritten by some PPA update or yum update.

I warn you, there is not a single good thing to be said about iWeb8 after our vast experience with them so if you want cliffnotes, picture a man shuffling through around 100 emails, invoices and chat logs while screaming in frustration. I’m attempting to piece together a structured account of our experience at iWeb8 Technologies through all that so bear with me here.
We run a non-commercial website that receives around 20 million page views per month. The problem is we quickly outgrew our technical know-how and had a pickle on our hands once our dedicated server at HostGator started buckling under the pressure. Friday is our most active day, as that’s when we have new content for our members – it’s also the day when our server became virtually inaccessible due to the traffic. We needed a solution, because HostGator basically told us to upgrade our machine or stop bothering them, [click here] for that story.
We narrowed our choices down to 2, SoftLayer or iWeb8 Technologies. We called them both up and learned about their datacenters and what direction we should go with our situation. SoftLayer’s salesman misunderstood a bit (as we later learned, more on that later) and offered us an overwhelmingly costly setup (upwards of $1500+ per month). iWeb8 ‘s sales representative “Brian” reeled us in with a couple promises –
1)The solution they outlined to us (2 web servers, 1 database server) would work.
2)If we opted for Level 5 management ($149/month) they would “treat our servers as if they were their own” (word for word)
We were very excited and worked out the details with them. We were convinced to go with a 12 month plan which would save us money in the long run. Our server manager suddenly switched from “Brian” to “Patrick Bertrand” at that point. And then the problems started.
The very first Friday we were fully set up on their servers, we crashed. We crashed under less traffic than our single cheap dedicated server at HostGator handled. It took iWeb8 1 hour to reboot our server. The next Friday, we crashed. We were down for 3 hours before we were rebooted. On 11/08/07 We asked for a hardware diagnostic and an inquiry into why we were crashing with pretty much twice the power we previously had – they told us we should add 2GB more ram to our servers for $50/month each.
We had them install the 2GB on one server to do them in phases, and thus minimize downtime. After the installation of ram that server performed far worse than it ever did before, and shot up to 100% CPU usage with 1 user online. This was my first experience with the post 6 PM Janitors who man their support staff. Apparently after that timeframe all the knowledgeable techs go home. After hours of waiting and talking on live chat / phone (to the same person every time, the only person who answered…) I was basically told that nobody there could do anything and I would have to wait until 8 AM EST for a senior technician to look at it. OTHERWISE, I could pay $180/hour or some ridiculously high number to get it immediately looked at. That Level 5 support really pays for itself huh?
I hired an emergency outsource administrator to look at it, he quoted me at $200 until the problem is resolved which was a steal. He found that I didn’t need ram at all. It was in fact my faulty motherboard that was causing the problems on that server. Ooooooh! Thanks for doing your “hardware diagnostic” properly and telling us to upgrade our ram for $50/month iWeb8, you’re really looking out for your customers. Finally at 12:15PM EST noon the next day it was looked at and replaced.
Exactly 1 week later on 11/15/07 all of our servers went offline for an hour or two. We were told it was a network issue and it was resolved. Nice.
Now here’s where the monster problems started. On the evening of Tuesday 12/01/07 all of our servers went offline. We opened an emergency ticket and the Janitor responded saying 3 apache modules were missing (huh?) and that it was fixed. Thing is, it wasn’t fixed at all. All 3 servers were still offline and unreachable. Finally our outsourced server admin gets into one of them and sees the load at 150+ with a ton of httpd threads open. He runs netstat and concludes we’re being DDoS attacked. Swing and a miss again, iWeb.
After exchanging pleasantries with the Janitor all night the senior staff finally got in at 8AM. His conclusion was to shut down apache and wait it out, since iWeb8 has no DDoS mitigation systems. Great. 2 days pass and nothing improves. We talk with our server manager to find out if we can terminate our contract and take our business elsewhere due to the pile of [expletive deleted] they’ve dumped on us ever since signing us, and the uselessness of “Level 5” support. He responds saying, and I quote
“Concerning level 5 support, have you requested the monitoring service alerts to be sent to our sysadmin cell phones ? if you did please provide the original RT number so that i can investigate to see why it has not been done on our side”
Wonderful. So you’re basically paying for nothing until you use your psychic powers to determine that you need to request something you thought was assumed with your $149/month. Nowhere when we signed up were we told we had to submit a ticket to request that our Level 5 support is useful. He also mentioned that the original salesman was “wrong” in offering us the phrase “we treat your servers like they’re our own”.
He responds again saying the website is working from his side. We test from 3 ISPs and proxies and we can’t connect, so no, it’s not working. Our server admin determined that their solution involved blocking pretty much all incoming traffic except their own range. We once again requested that the contract be terminated, as we were blatantly lied to on multiple occasions and they’re threatening our website with their poor level of service. He says he needs to discuss it with the higher ups.
At this point I’d already moved my sites to a 2 web server 1 database setup at SoftLayer, they put my site under their Cisco Guard and their team actively worked against my DDoS attack, ending it within a few hours. I’ve been happily at SoftLayer ever since 12/5/07 without any issues on this setup. See my review of them by [clicking here].
Anyway, on 12/17/07 iWeb sends a global email to all their customers informing them that “Improvements will be made to night and weekend customer service”, thus admitting that they were actually manning their Janitors – too little too late though.
On 01/15/07 we still hadn’t heard from them (except for a couple dozen invoices that failed because we weren’t going to send them anything until this was finalized), so we talked to our lawyer and threatened legal measures on iWeb8 if we didn’t hear from them so that we could terminate the contract. On 01/16/07 we got an email from Patrick Bertrand confirming that the contract could be ended, they would send us the details later.
Turns out the details was they wanted 20% of the remaining contract value to terminate, which he ensured me was a “good deal” because “he knows his company and this is the lowest they’ll go”. Is he trying to sell me a car or what? At this point it’s whatever, if we can pay $1,495.26 (20% of the remaining contract) to make the iWeb8 nightmare end, let’s do it. So we did, on 01/25/08 we paid the entire amount and our contract was effectively terminated.
Now in March the nightmare returns. We receive an email from them demanding that we pay $740.00 for “services” rendered from the period of when he said he’d talk to the higher ups till we were waiting for them to do virtually nothing until we called them up in January.
At this point we’re weighing the option of paying off these swindlers and being done with it once and for all (even though they’ll probably come back to us in June with “interest” invoices on this current one) against fighting it. That’s where we’re at now… I hope this was enlightening for you if you’re considering falling for iWeb’s lies, random surcharges and all in all horrible service.

Today I found some cstomer on the servers make a link for named it file.txt and link it to other customer php file.
so that customer have the ability to show the other custoer file content when visiting the url because it is a text wile originally it is a php file.
the php file was a config file, so now he know the database password , and because he is in the same server he can use that databse.
the question , how to avoide this prolem in the future?
notes , the SuExec is rnning and the open_basedir protection is enabled, but the problem still exists.

When deploying new server/servergroup/cluster to your IT infrastructure, deployment (simplified) consist of following steps:
OS installation: to do it over network, boot server must be configured for this new server/servergroup/cluster,
configuration/package management: configuration server has to be aware of the newcomer(s),
monitoring and alerting: monitoring software must be reconfigured,
performance metrics: a tool for collecting data must be reconfigured.
There are many excellent software solutions for those particular jobs, say configuration management (Puppet, Chef, cfengine, bcfg2), monitoring hosts and services (Nagios, Zabbix, OpenNMS, Zenoss, etc) and performance metrics (Ganglia, etc). But each of these tools has to be configured independently or at least configuration has to be generated. What tools do you use to achieve this?
For example, when you have to deploy a new server, how do you create configs for, let's say, PXE boot server, Puppet, Nagios and Ganglia, at once?

I seem to be having a problem where periodically the data in one file is getting corrupted. I haven't been able to figure out a pattern to it, so I wanted to run command by crontab that would create a copy of the file each day. To avoid overwriting previous backups the filename of each day's copy would have to be unique like...
cp filename filename-2008-07-03
Is there a way to include this year, this month, and this day variables in a linux command?

I built a web hosting server, the following is its state
Cent os 5
AMP server loaded updated (installed it as a complete suite during installation so it was all set to go with php mysql modules loaded)
webmin
usermin virtualmin
created 2 named based hosts.
now when i load up wordpress in a site and try to run install.php
the following pops up
"Sorry, I can't write to the directory. You'll have to either change the permissions on your WordPress directory or create your wp-config.php manually."
I had this issue before and research said to redo the entire server (tried everything and was fed up had fedora then"
you can have a look at www.itgrunts.com just click create config file and the errror pops up.
The php and mysql db work great on simple scripts but i dont know why this happens.
i worked with assigning the users and apache user to the directory and everything, no joy.

On my previous server and on some other hosts, I was able to write to files (for example with PHP) without having to chmod the files first.
Now I cannot, and files are required to be chmoded properly so I can write to them.
I cannot even touch() a file with PHP.
Is there any way to have this permissions removed?
I don't want to chmod the all thing, all I want is to change the configurations so I can fwrite() or file_put_contents() normally.
I's a dedicated un-managed server, so basically any advanced configurations can be done.

It appears that some people like to take advantage of those files for online web applications such as Wordpress which have php files with permissions set to 777. They use those as a means of creating an upload file. The upload files that they create then have access to the whole server somehow... Is there anyway of preventing this from happening?

I have download manager script that I use for my customers to download products right after the purchase.
Script generates download link that looks like this:
http://www.yourwebsite.com/download/...582921B&p=1840 (where 2YY6582921B is receipt number that is different with each purchase).
All products are placed in one folder. This folder can not be seen in above download url, but can be accessed thru browser and files can be downloaded that way without paying for them.
Can I use .htaccess and if yes how, to protect all product files the way that they can not be accessed directly by visiting url thru browser (in case somebody will find the correct url), they should be allowed for access only for my download manager script.

I have anywhere between 80,000 - 90,000 webpages that have a single code into this. Unfortunately at the time the web developer I used didn't use PHP includes. So each .html file has the code in it.
I want a way so I can do a single command either a program or an SSH command can find the syntax in the files and replace it will code I have. Its just a single line of code that is basically for an adsense code, so the pub-blahblahblah etc..
Does anyone know of a SSH command I can use, or a program that will find and replace without manually opening up each file? 80k - 90k of opening files then find/replace will take forever!

I recently had an issue where my box wasnt listing accounts (on logging into WHM for the first time it would, thereafter browsing different functions in WHM it would fail to list any accounts), would not list any zone items when editing DNS zones and in general was acting very strange.
I think the tech support chap narrowed it down to zero free inodes on the filesystem (i was even getting errors when editing files with 'vi'). This was increased for the VPS and all issues seemed to be resolved...
However named and httpd were not starting after reboots. Again on looking closely named and httpd were missing from /etc/init.d (on CentOS 5.3)! This is very strange and i certainly didnt modify those nor delete such critical files.
For a second opinion, is there any cPanel script that can be ran to fix the issues, i am concerned other things have been affected but havent manifested themselves yet (other files deleted etc). Does cPanel update script create the init.d files or is this done by the CentOS operating systems itself? Are these files modified during a cPanel update script?
These init.d files for named and httpd have been readded (copied across from another box) and it seems to be ok again, but ideas on howto proceed much appreciated, as i mentioned i dont want any nasty supprises!
