Chmod Choices With Php Writing To A File
Aug 31, 2008
My account has been hacked with every index.php page defaced. I've cleaned up and my shared wehost is pointing at me saying there shouldn't be any 777 permissions for any files in there.
I used 777 to allow php to add records in a txt file and in an xml file.
Is there a better / more secure chmod code I can use?
Those are the only two instances where I need php to write to a file and those files shouldn't be served to anyone, I do not want anyone to be able to access them.
How can I secure them while letting php write in them?

I wanted to make a cronjob with rsync, but I was wondering what happens when a user is uploading a file and the file is being created and at the same moment rsync synchronizes with another server.
Will the file be skip, partially be synced, ...?

How do I sweep my entire server and chmod a particular filename located in the cgi-bin to either 0, 755, etc?
For example, to disable a particular perl script running on my system on over 100 accounts in the /cgi-bin/file.cgi I want to chmod the file on every account that it comes up on that /cgi-bin/file.cgi needs to be chmod'd to 0.
Anyone know how to do this thru ssh or another method?

I am looking for a VPS host in the $50 dollar range for 2 small to medium sized vBulletin forums. I have read about RAM usage and hope that the price I can afford can handle a not so big vBulletin forum or two, I will optimize them anyway but still. I am also concerned about mysql max connection errors.
Two, among others, of the names that I keep seeing good things about are liquidweb and jaguarpc, however I notice through google cache that liquidweb used to have a customer forum, but it doesn't seem to exist anymore? maybe there is a good explanation that I am missing? but support forum not existing anymore doesn't sound good in my opinion.
Jagaurpc's own forums has around 30 'emergency maintenance' threads over the last 6 weeks alone, again that doesn't sound good to me, even if it means that they are on top of it still so many 'emergency' situations can't be good?
Of course I prefer to have managed VPS as the above two seem to offer and helpfulness especially initially during setup. I hope to get opinions on these couple of issues specific to them and general recommendations on VPS

I've searched on this site, and there are quite a few posts about selecting appropriate switches for different applications. I'm looking for similar advice from the networking gurus out there.
I need a reliable switch (probably only need L2?) to connect 6 Sun Fire X2100 servers in a colo rack. Each server has two network ports. I use one for the public addresses; and the second for a private, management network.
In an ideal world, I'd love to run the servers diskless, and consolidate all the drives into a separate, dedicated storage server running Solaris and ZFS. I'm guessing that I would need GigE ports on the switch to get maximum performance out of an iSCSI SAN?
That might push the price much higher though.
I'm currently running 3 of these servers with a Catalyst 2912XL, and I've been very pleased with the reliability of this switch (and it was super cheap on ebay). It's setup with two VLANs (one for the public net, one for the private net). The thing has been running for about a year without a single reboot.
While Cisco seems to be the favored brand, I'm considering a few other choices as well...
Foundry EdgeIron 2402CF
Extreme Network Summit 200-24
Cisco Catalyst 2950-24
Cisco Catalyst 2960-24
Just wondering what the pros and cons of these various units might be. And do I need a separate (GigE?) network for iSCSI, or could it function on the same interfaces used for the management (and MySQL) traffic?

I use APC Netshelter cabinets now; I have a need for some cabinets with 23-inch wide rails, capable of holding telco muxes, rectifiers, batteries, etc. Any suggestions on cabinet?
Something that would blend in with APC Netshelters (black, bowed/curved door on cold aisle) would be nice. I know I've seen a cabinet very similar to Netshelter delivered from NetApp, but with a grey/off-black color, and 1-piece door on the hot aisle. If APC is just sourcing their cabinets from some manufacturer who takes engineering requests, it would be great to find out who makes them.

I'm trying to change url structure so instead of /default/category/product.html it would show /category/product.html
With this line I've managed to do it on my personal blog
RedirectMatch 301 /default/(.*) //$1
But when I've implemented it on a customers Magento site it started showing double slashes like this //category/product.html and the whole template just collapsed .

I've just moved from a reseller account with ResellerZoom, so a VPS with SolarVPS.
When I was with RZ all my scripts could write to folder with the 755 permissions. On the vps I have to alter the folder I want the script to write to to be 777.
Which the is best and most secure?
I think I understand that if a folder is 777 then anyone on the server can write to that folder. So I assume some sort of thing that stops users being able to access folders outside of their own folders is needed? is that right?

I have a server running php 5.2.4 with CGI as Server API and suexec, but I cant create dirs in php with chmod 755. When I use mkdir("/home/user/public_html/$dirname", 0755); it creates the dir with chmod 744. Why?
I can change later this chmod to 755 in php with the chmod function. But why my server doesnt allow the directory to be created as 755? Where can I configure it?

I know you're not supposed to use 777 but it seems some scripts just simply won't work without it, what steps needs to be taken to avoid using 777?
as far as i understand we're only supposed to use 775 for folders and 644 for files correct?

I've recently moved to a new server in which I don't have root, so bare with me.
For some reason when I upload a file with 'move_uploaded_file($tmpName,$new_filename)', it seems to work fine - but when I check it, try to download it (http or ftp), or change the permission - I can't, because its set to 600 for some odd reason, and owned by the user Apache is setup on.

I have my web server hacked several times and I am beating my head against the wall trying to find the problem(s).
Way back when my sites have been defaced and CHMODing my *.html files to 744 seemed to have done the trick
Now someone has put a phishing site somehow, which by the way I'm not able to remove still, I can't help but to think that I may have more CHMODing to do, I have recursevly set my site to 755, shoud this do the trick? I know I need to chmod .htaccess and alike files to 644, but what about...imagesCGI/PHP?cssetc?
What other steps can I take to secure this thing?
it's a shared host, limited access, but I do have SHELL.

I got a VPS with Linode and I have installed CentOS 5.2 32-bit, Apache, MySQL and ProFTPd. The server itself runs very OK, however, I have issues with running 'chmod' on the user interface with either FileZilla or CuteFTP pro.
Whenever I try to chmod 777 on a directory, I got this error on the FTP client interface:
Quote:
Command:SITE CHMOD 777 includes
Response:550 CHMOD 777 includes: No such file or directory
Why no such file or directory? weird. It's just on the server though. The FTP user is the owner/group of the directory I try to chmod to.
But I am able to run chmod on Putty.
