  • Is this a solution for having multiple SSL certificates on the same IP

    - by Saif Bechan
    I am running CentOS running on a VPS. I read some guides on having multiple SSL certificates on the same system, but I can not get the basics to work. The guide I got that makes the most sense to me is the doing the following. In CentOS I can make virtual NIC's. So I made 2 virtual NIC's to start with. 192.168.10.1, 192.168.10.2. Now I work in ISP manager Pro, so this is listening on my primary ip 1.1.1.1 For each website I have them listening on 192.168.10.1:80, 192.168.10.1:443 In the hosts file I made the following 2 entries 192.168.10.1 1st.com 192.168.10.2 2nd.com Now the strange thing is that when I browser to 1st.com I do not get the website located at 192.168.10.1, I get the website located at my prim IP 1.1.1.1 Should I do something like forwarding or routing for this setup to work? And the basic question: Will this setup even work? Are the SSL certificates based on the IP adress, or are the based on the host name, 1st.com and 2nd.com.

In the second window. click on radio button "The server maintains the zone" and then click next.

In the next window, click on radio button "No it should not forward query" and then click next button. Complete the configure a DNS server wizard and then click on finish button. After it is managing the DNS records: In DNS server wizard. open tree of forward lookup zone and right click on the new zone name "example.com" - properties and click on "Start of authority" and write values on text boxes serial number=1 primary server=systemname.domainname responsible person=hostmaster.domainname Click on server name, highlight domain name, click on edit button and enter IP address of the server where I host my application. Highlight new zone name and right click on it and click "New Host" option. In this window there are three text boxes: Name(user parent name if blank)=scoring Fully Qualified Domain Name=scoring.example.com IP Address= My IP Address and check on "Create associated pointer(PTR) record" and click on "Add Host" Host button and then click done button. I have host header for my application is "scoring" on port 80 and its working fine on server my application setting are I have change its, Advance setting --> Application Pool Identity --> Local System application can access on server with host name "scoring" but it can not access on machines on LAN. When I change LAN machine host file that is under, C:/windows/system32/driver/etc/host and edit it and enter host name with hosted machine IP like this: scoring 192.168.1.20 By making these changes I can run the application over LAN machines as I mentioned above DNS setting by which I can run App over LAN with out editing the client's host file. What mistake am I doing in this configuration?

  • Which iptables rule do you think is a 'must have'

    - by Saif Bechan
    I have some basic iptable rules set up now for my vps. Just block everything except some default ports, 80,21,22,443. I do get brute forced a lot. I have heard that iptables is very powerful but I have not seen many use cases. Can you give me an example of a(some) rule(s) you always use and give a small example why. I can not find a general best practice post here on SF, if there is any I would like the link. If this is a duplicate I am sorry and it can be closed.

I recently opened my logwatch logs and saw that i get attacked a lot by all sorts of bots. Now I am interested in a list with things I definitely should be aware of nowadays, and possible ways to prevent them. I have read stories about server crashed by floods, crashed by email, and all sorts of crazy stuff. Thing I already did: I have recently blocked all my ports, except for the http and email ports. I disabled IPv6, this was giving me a lot of named errors I have turned on spam DNS blackhole lists to fight spam - sbl.spamhaus.org; - zen.spamhaus.org; - b.barracudacentral.org; I installed and configured mod_security2 on apache There is no remote access possible to my databases That is all i did so far, further I am not aware of any other threats. I want to know if the following things have to be protects. Can I be flooded by emails. How can i prevent this Can there be a break in or flood of my databses Are there things like http floods or whatever Are there any other things i should know before i go public with my server I also want to know if there is some kind of checklist with must-have security protections.

Or will Gmail cover all of this.

  • Creating multiple profiles in Windows Mobile

    - by Saif Bechan
    I have a HTC HD2 which runs Windows Mobile 6.5. The way you can integrate different accounts is just amazing. You can integrate facebook,twitter,youtube. You can also sync your mail, and calendar from Hotmail or Gmail. It all works just great. Now my problem is that I have different profiles. I have my personal profile, and on the other side I have work profile. My work email is on Gmail Apps, so I have a mail and calendar there also. I also have a personal facebook account, and one I use for work. So my question is if there is a way of switching between these profiles quickly.

  • Managing multiple independant domains with Google Apps

    - by Saif Bechan
    I am currently running a server where I have multiple domains with all of them running there own mail server. My plan is to outsource this whole email service and have Google, or competitor, do this for me. Let me start by telling you the setup I have now and want to migrate to Google. Initial setup I have a main domain where I run my server, and my nameserver. This is an important domain because this holds the connection with all my internal applications. For example log messages, cronjob messages, and virus-scan messages are sent to this domain. This email is also registered at my registrar and I use it to communicate with my ISP. Next I run a few independent websites that all need their independent email addresses. This can be on shared space, I don't mind. 1 Gig will be enough for everything I am going to do. Summary: superdomain.com (which only has a catchall for internal use and communication with my ISP) cars.com (independent) flowers.com (independent) foods.com (independent) I am going to be the admin for all of this. The independent domains don't need there own admin panel, they just need email addresses like info@ support@, etc. I do all the managing and they just send and receive emails using the accounts i give them. All of the websites have there different staff that use the accounts. Tried so far I have registered my superdomain, but I can only add aliases to the main domain. If I make all the other domains aliases the emails from [email protected] and [email protected] will have the same inbox. I want them to be separate. is the only way to achieve this by creating an account for each domain? And if so, is there no way of creating a superdomain account where I can edit all these accounts easily without having to log in 4 different places to get my work done. I have searched the Google help forums, and posted questions but without any results so far. Questions Can anyone please give me some advice on what to do. I currently use the free program Google has.

  • Using Google's App Engine as CDN for static files

    - by Saif Bechan
    I am planning on moving my static files to Google's App Engine. I was wondering if this is a good idea to do. I have read that is it possible that Google will cache your files on multiple locations, which is a good thing in my opinion. The setup should also be quite easy in eclipse with the GAE plugins. But i still have my doubts on the performance of this. Is the setup of App Engine optimized for serving static content. Now I have Nginx server my static content, will App Engine perform the same way. Are there any other ups or downs using this method?

  • Why cache static files with Varnish, why not pass

    - by Saif Bechan
    I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

  • How to tell if you are connected to Wireless B, G or N?

    - by Raheel Khan
    I am using Windows 7 on all wired desktops and wireless laptops in my home network. I recently upgraded my Ethernet switch to Gigabit and instantly noticed an increase in throughput in wired devices. I also bought a Wireless-N WAP but with degredation in wireless file transfer speeds. I have been told that a number of reasons could affect wireless speeds including which WAP is used, how many wireless devices are connected, which security mode is used, etc. However, that remains irrelevant to my question. Each of my laptops claim to support Wireless-N but I cannot seem to figure out how to determine if the laptops are truly running Wireless-N or are connected to the WAP through some sort of mixed-mode. I do not have control of the WAP device so cannot tell what mode it is running in. Is there a way to tell which mode is being used and what the throughput is for each connected device without having access to the WAP interface?

  • where is this SFP problem occuring

    - by Saif Khan
    Hi, Inbound mail to a specific user is been forwarded to his external mailbox at another domain. Add mails are routed correctly with the exception of one domain. When mail are sent to users of my domain, including that user, the mails are delivered to everyone except him...as the mail admin I am getting the message The following recipient(s) cannot be reached: usermailbox on 1/10/2011 1:27 PM There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. email.speedimpex.com #5.5.0 smtp;587 [email protected] sender domain does not match SPF records I am sure this has nothing to do with my mail server, however, can someone confirm?

  • How to setup a fast VPN server

    - by Saif Bechan
    I am trying to set up a VPN that has a fast download speed. The server I have is a linux server and from there I can download 2 megabytes a second. At home I can also download with 2 megabytes a second. All the downloads I do are from the same source, no different server. Now I have set up a VPN connection between my home and the server, and now I am only downloading 64 kilobytes a second! The connection I have created is a PPTP server on a debian machine. Now my question is if it is possible to optimize this connection. Should I maybe switch to OpenVPN, or change operating systems? Or are there some kind of settings to tweak to make the connection optimal. PS. The server I am running is on a XEN node. I have done the proper ip forwarding.

  • Share in inbox in Google Apps Standard

    - by Saif Bechan
    I have recently signed up for the Standard account of Google apps. In my company I have certain email addresses that are handled by multiple users. For example the support emails are handled by multiple users. Now I have just multiple users log into the same account, but this is not a good practice. It can get quite messy when some emails are handled by different users but on the same email address. Now I looked into the groups option. I have made a group for [email protected], and added all the users to the group. Now everybody gets a copy of the support message sent. But its got a bigger mess because the users don't know who handles which message. Is there some workaround to this so I can make good use of this all in this way.
