Some articles on the Net seem to suggest (may be I have misunderstood it) that S/MIME, which uses x.509 certificates is better for implementing secure email as the sender can use the x.509 cert to encrypt and digitally sign the messages and the recipient only needs an email client that implements x.509.
Is this true? Or, will key pairs still need to be generated and the public key shared with the recipient in advance even when using S/MIME?
I have a problem with a .dat file on my webserver. It seems to download correctly (I have added the mime type), but my application refuses to use/read the file correctly.
This is moving from an Apache server, where it worked perfectly, to IIS6. Apache reported the mime as text/plain, whereas I've tried both this and application/octet-stream on IIS.
The dat-file is actually a ZIP password protected file containing an XML-file.
Could there perhaps be some issues with dato format? I'm most greatful for any insigth into the matter.
I have an IIS 6 website with a strange problem. All content types are sent as text/html. For example, jpegs, gifs, and others all are listed as text/html when I do a header check. Anyone ever seen this or know what might cause it?
View 2 Replies View RelatedWhenever I try to validate a page on my website it says it's invalid because the mime type is incorrect.
If I add this code to the top of the page:
PHP Code:
<?php
header("Content-Type: text/html");
?>
The page then becomes valid.
How can I update the mime type on the server so that I wont have to add this code to every page?
My server is a VPS running Apache with Plesk. I have SSH access.
any hints on the reason of "--with-mime-magic: not found" when compiling PHP?

I've got mod_deflate set up with Apache with the following line in httpd.conf:
Code:
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript
</IfModule>
It works well, for most things.
The issue I'm having is that mod_deflate is compressing binary data, outputted from PHP scripts as well (undesirable).
The script sends a Content-Type: application/octet-stream header, so I'm guessing that mod_deflate is simply not looking at headers generated by the script before compressing output.
I've even changed the default MIME type for Apache to application/octet-stream but to no avail.
Note that static content which has a defined MIME type doesn't get compressed - it's only the output generated by scripts.
Also, there is no defined MIME type for the .php extension.
I've also tried to disable the filter for certain directories, however, Apache doesn't seem to have an opposite to AddOutputFilterByType (although it does for AddOutputFilter (RemoveOutputFilter)). Also, I can't seem to stick in a negative <Directory> command either, which is a pain :/
i run an Internet radio station, and my current web host doesn't support the MIME Types i need for people to be able to click on the links to listen to it
so im looking for a new web host with cpanel preferably. and supports these MIME Types
PLS - audio/x-scpls
ASX - video/x-ms-asf
I'm running plesk 11.5.30 and I'm having an issue with the new word doc format (.docx) being recognized as a zip file. I've read several posts that explain what mime types to add, and I've found the spot where I need to enter them. The part I'm not sure about is whether the custom mime types field is an addition to the current mime types or a replacement list. Does that field just needs the new mime types or a full list?

when I get a dedi server for shared hosting. I secure it as much as i can and then just incase I miss stuff etc I hire 2 other companys to check over everything. Since I bought a vps from fsckvps are there any guides to secure and optimize a vps other then the one located in the vps section? thanks. I Dont feel like spending 50+ dollars on securing a vps that costs less then 15 a month.

How secure is my VPS? Anyone who has some free time and is reading this thread could please try to do some penetration-testing or something related (I really do not know much about network security) in order to know if my server configuration could be the problem?
Do you find any way to download the full database without login on the system (cPanel or phpMyAdmin)?

I have an application that requires a Secure FTP connection to a server to work. I am having trouble connecting to one server, a windows based server, while the CentOS Linux server is working fine.
Does anyone know where I can find test Secure FTP locations so I can determine if the issue is with misconfiguration or with an incompatibility of the program with windows Secure FTP sites?
I am able to connect to both sites using WinSCP and choosing Secure FTP.
Check out this blog and suggest what thing more can be added to secure the vps and i think this information database can be helpful for newbies and intermediate users which like to secure the VPS.. which sometimes exploited due to bad scripts.

Ive been using Dreamhost for years and there great however, One of my clients needs has drastically changed and they are now required to comply with the Data Protection Act.
In particular this bit make Dreamhost a bit of a no go due to them being in California:
"Personal information may not be transmitted outside the EEA unless the individual whom it is about has consented or adequate protection is in place, for example by the use of a prescribed form of contract to govern the transmission of the data."
Unless my client goes and asks all 1000+ customers they are kinda in a bit of a quandary. So here's what im looking for:
Secure UK Datacenter, eg Easynet, Blue Square etc
128mb RAM, 256mb Burstable, 20GB storage, 500GB transfer
LAMP Environment
Support within Business Hours
Control Panel
So I just got SVN installed on my server, and now I'm wondering about the best way to go about securing it. This is what I've had done so far
the executables were installed to /usr/bin as ROOT
Then I created a directory in /usr/local/svn as ROOT to hold the svn repositories (the conf folders, etc).
I've decided that I'd like to use the SVNSERVE tool rather than have to run Apache2 which my current VPS provider does not provide any support for.
So I've run SVNSERVE like so:
svnserve -d -r /usr/local/svn --listen-port=7126
Then for each repository within the /usr/local/svn folder I've gone into the conf folder and added:
anon-access = none
auth-access = write
password-db = passfile
realm = myrealm
The passfile is located in the same directory (ie. /usr/local/svn/test) and contains my users in the format:
[users]
harry = harryssecret
sally = sallyssecret
I then run my checkouts like so:
svn checkout svn://mysite.com:7126/test
Now my question is how secure is this. I was tempted to use svn+ssh but I couldn't seem to figure out how to get it configured. Is the protection I have adequate? How easily can this be compromised? What steps should I take to lock it down further. Can I limit the connection to SVNSERVE to only come from certain specific IP's... similar to how apache does:
Order deny,allow
deny from all
allow from 192.153.123.12
What would be the most secure free CMS at the moment? I ask this because im looking to setup a website, and i dont have enough money to invest in a custom coded website, so to start out with ill use a free CMS, but i dont want to be hacked.
Now i know that because the CMS's are open source, they can still be hacked, what im looking for is something that is the most secure, preferably with sql injection protection.s?

recently I got a VPS from cheapvps.co.uk and so far so good. Im getting used to the VPS enviroment. I tried to follow several guides about how to secure with noexec and nosuid the /tmp and /var/tmp and it did not work.
in http : / / www . webhostingtalk .com/showthread.php?t=474681&highlight=tmp points it must be done from the hosting. Same is said in http : // kb . swsoft . com/article_130_648_en.html.
I asked the hosting to do it and they told me as I got an Unmanaged VPS they cant do it for me.
Do anyone know how can be done ? I dont want to use tmpfs as it uses main memory.
In terms of the secure domain, if I had a secure site and wished to access some information on a web page that was from a NON-SECURE domain or at least duplicate the non secure information on to the secure page, does the user need to click acknowledge buttons to go in and out of the secure areas? Can I copy or transfer information [eg goggle search results] onto the secure page without this necessity?
View 6 Replies View RelatedMy requirements are 500MB, 5GB bandwidth, rails and postgres, $5-6 per month. It looks like there are many providers out there that are offer that.
However the only uploading method shared hosters seem to offer - or at least the only method they advertise - is FTP. Coming from a university and sysadmin background, I thought that anything that sends passwords over the wire unencrypted had died long ago (except HTML forms and legacy systems).
Are there any shared hosting services that allow a more secure upload method (e.g. scp, rsync-over-ssh, even webdav-over-ssl)?
am getting this repeated error line in in log/secure
