FMC allowed New contracts to MCX in 2015

Tamilnadu 30th Sep 2014: 
MCX exchange has been permitted to launch fresh contracts in commodities such as gold, silver, aluminium, lead, nickel, zinc, copper, natural gas, brent crude oil, natural gas, crude palm oil, mentha oil and cardamom among others, it said.
The approval was given immediately after Financial Technologies (FTIL) signed a new technology pact withMCX and concluded today the sale of 15 per cent stake in the commodity bourse to Kotak Mahindra Bank for Rs 459 crore. Signing of such a pact was a pre-condition to conclude the stake sale.
FMC had held back approval for launch of new contracts to MCX to ensure that the bourse puts pressure on FTIL to comply with the December 2013 order that declared FTIL as unfit to run any bourse in view of the Rs 5,600 crore scam at National Spot Exchange (NSEL). NSEL is promoted by FTIL.
In its latest circular, FMC said that the contracts to be launched by MCX in the next year should be subject to regulatory norms. The contract specifications should also be as approved by FMC and the directions issued by the regulator from time to time.
MCX should send a monthly/quarterly report on functioning of the various contracts. The exchange should also ensure that there is no "unhealthy speculative trading" in the market, which may result in cornering or artificial rigging up or down of the prices by a particular member or group or class of members, it said.
"If trading in the above mentioned contracts results in excessive/unhealthy speculation, the Commission will intervene and impose stern measures to deal with the situation and if the situation so warrants, revoke the permission granted to any or all the contracts," FMC cautioned.
As far as agricultural contracts are concerned, apart from the approved quality standards, the Exchange should ensure that the commodity deposited should comply with the regulations laid down by the other authorities like Food Safety Standards Authority of India, AGMARK, BIS etc, it said.
MCX is a leading commodity bourse in the country. Its volumes have taken a beating after the scam at NSEL surfaced and imposition of commodity trading tax.
The turnover of the exchange was Rs 2,06,876 crore in the first fornight of this month, down from Rs 2,71,348crore in the same period last year, as per the FMC data.

How to control Linux server or Linux VPS from Windows


Controlling a Linux server or Linux VPS from Windows operating system  can be done with SSH  (Secure Shell) . Windows requires a tiny software named PuTTY. PuTTY is a free to download, small, stand-alone application that lets you connect to servers over SSH on Windows. Windows doesn’t come with any software for SSH  so we really need a third party application for that. PuTTY can be downloaded here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html. You just need ‘putty.exe’. Download it and put it somewhere to your liking. It doesn't require anything else, so just launch it after downloading it. This should show Putty's default screen:



















In the ‘Host Name’ field, Type the hostname or IP address of your server. I have chosen to use the IP address here. Now hit the ‘Open’ button. You should get a prompt titled ‘PuTTY Security Alert’. No worries, this is completely normal.
















This prompt asks you whether you trust the host. It shows the host’s RSA fingerprint. SSH uses this fingerprint while connecting to see if the server is actually the same as it was before. In order to be able to do this, it needs to have the fingerprint first. So it prompts you whether you trust this host the first time you connect so it. If you say “Yes”, PuTTY will save the fingerprint in the so-called known_hosts file and use that to compare with the host’s RSA fingerprint on future connection attempts. If the host’s RSA fingerprint doesn’t match the known one, the host either got reinstalled or the host is not the one you think it is (possible indicating an attack). So, a quite useful mechanism altogether. Accepting your host’s RSA fingerprint should move you on to the next screen, the actual terminal:

Here it asks you for your username and your password. In this case, I have used ‘root’ as the username. Type in your password and hit enter, this should give you a window like this (on Ubuntu hosts):













You have successfully logged in to your server over SSH! Congratulations! That’s how simple it was.
From here on, you’re on your own from now on. You can use commands like ‘cd’ and ‘ls’ to move around a bit and explore your system, but more on that in a future tutorial!

Thanks:  Maarten Kossen

How to Add IPv6 to CentOS VPS


How to Add IPv6 to CentOS VPS














How would I add an IPv6 address to my  CentOS based VPS?
First you would want to make sure you have the /etc/sysconfig/network-scripts/network-functions-ipv6 script.

sh-3.00# ls -l /etc/sysconfig/network-scripts/network-functions-ipv6
-rw-r--r--  1 root root 42087 Jun 25  2008 network-functions-ipv6
sh-3.00#

Now that the IPv6 script is on the VPS, the next step is to check if the net-pf-10 module is loaded in your centos based VPS. We can do this by running the following commands:

sh-3.00# modprobe -c | grep net-pf-10
alias net-pf-10 ipv6
sh-3.00#

The above output shows the VPS does have it. If the VPS did not have it, you would get this output.

sh-3.00# modprobe -c | grep net-pf-10
alias net-pf-10 off
sh-3.00#

So if it is off on your VPS you would want to edit /etc/sysconfig/network and enable NETWORKING_IPV6.
Here is an example of what a /etc/sysconfig/network with IPv6 would look like.            

sh-3.00# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=ipv6test.softlayer.com
GATEWAY=10.12.12.1
NETWORKING_IPV6=yes
sh-3.00#

Now you will want to restart your networking service. You can do this via the /sbin/service network restart command.

sh-3.00# /sbin/service network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down interface eth1:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Setting network parameters:                                [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:                                [  OK  ]
Bringing up interface eth1:                                [  OK  ]
sh-3.00#

Now you will want to edit your /etc/sysconfig/network-scripts/ifcfg-eth1 file to add the IPv6 parameters.
Add the following

IPV6INIT=yes
IPV6ADDR=YOURIPV6ADDRESS
IPV6_DEFAULTGW=YOURGATEWAY
Here is an example of what a IPv6 portion should look like.
#IPV6 configuration
IPV6INIT=yes
IPV6ADDR=2607:f0d0:2001:0000:0000:0000:0000:0010/64
IPV6_DEFAULTGW=2607:f0d0:2001:0000:0000:0000:0000:0001

After you add that you will want to restart your network services again
sh-3.00# /sbin/service network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down interface eth1:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Setting network parameters:                                [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:                                [  OK  ]
Bringing up interface eth1:                                [  OK  ]
sh-3.00#

Now you should be able to communicate over IPv6. You can ping ipv6.google.com and see if it works.

sh-3.00# ping6 ipv6.google.com –n
PING ipv6.google.com(2001:4860:b002::68) 56 data bytes
64 bytes from 2001:4860:b002::68: icmp_seq=0 ttl=59 time=86.6 ms
64 bytes from 2001:4860:b002::68: icmp_seq=1 ttl=59 time=86.9 ms
64 bytes from 2001:4860:b002::68: icmp_seq=2 ttl=59 time=84.8 ms
--- ipv6.google.com ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 84.870/86.130/86.913/0.961 ms, pipe 2
sh-3.00#

Free Web hosting Control Panel Comparision

Free Web hosting Control panels and their Features



ISPconfig: Good solution, it is more of a GUI controlling tons of vps functions (Apache/nginx, mysql/mariaDB/Postgre, php, mail, ftp, firewall etc) than a simple control panel. It can create resellers and users with moderate control of their account.
Little tricky to install it (you have to manually install all elements as Apache, mysql, php, mail, ftp etx.) but has best tutorials on how to setup in several flavors. Just see howtoforge or search google, there are extremely detailed instructions on over than 50 different configurations).
Good and easy interface for end users, can interact with whmcs.



Webmin/Virtualmin: A web control panel that has it all, but it has weird interface for noobies and end users. Tons of options (not just a control panel) but it need good knowledge of handling a server and administrate linux. You can do almost anything to maintain/control/update/fix your server (vps, dedi etc) and your sites, but it is difficult to tune it. You have to be an experienced user, if no, do not use it in production environment.




VestaCP: Easy to install, easy to use, it lacks on functions. For basic vps managing, it is fine. Very easy for the end user.


Ehcp: No frequent updates, but still active especially for patches/fixes (latest patch is on 11/9/2014). Good and nice interface and option to use different ones (there are 8-9 different layouts in-the-box). Easy, stable and lightweight, but works only in Debian/Ubuntu likes.


Zpanel (now Sentora): PROS: Very good and stable control panel, very easy to handle especially for end users. CONS: Had many many many security problems in the past, that the community behind it says there are not existing any more.
BE CAREFUL: providers and programmers here still saying that this software has a lot of security holes and the Zpanel/sentora community does not willing to fix them or even to admit that there are holes (I am not a programmer, do not have this kind of knowledge of coding, so, I cannot have mine opinion on that. But with so many warnings from LET Community, you should be careful).
UPDATE: Sentora Community has new owners than the zpanel past. Bobby Allen has quit the new community due to conflicts with the owners of zpanel project (he sold zpanel to hostwings some months before but I think now his relation with them is not good, so, he decided to withdraw from both projects for now). The team now is leaded by some old dev members and some new, and has grown up a bit. I don't know if this is a change to a good direction for making sentora more secure, time will show. But their community is up again and most of people there seem to be willing to help and listen to criticism. Again, time will show...

Kloxo: No, nein, niet, ohi, no way. It was the king of the free cpanels once, now it is an almost dead project, weird and dysfunctional in today's standards, with a ton of security problems and outdated. Stay away

Kloxo-MR: Mustapha's fork of Kloxo. He is the main developer and did a good job to close Kloxo's holes, update it with many functions and fixes, he is active and he is doing a good work. But there are still issues (functionality, ease of use etc.) as it is a fork that has been built on original Kloxo.

There are some more:

i-MSCP (medium, lack of options, clean and easy interface)
Froxlor (medium, lack of options, clean and easy interface)
Ajenti (based on Ajenti server control panel, not easy interface, not tested by me, I only installed it once to play a little with the interface, didn't like it)
Bailfox (very minimal interface, has all basic options though. Not tested by me)

Recommendations:

ISPconfig (need work from you to install it, but very easy for your end users)
VestaCP (very easy to install, very easy for end users, minimum options to control though)
Virtualmin/webmin (Very easy to install it but very tricky to configure/tune it. Difficult interface for administrator and for end users, recommended highly but only for experienced users)
