Binary : if you want to copy files in binary mode.

Cd : Change directory on the FTP server

Dir : List the names of the files in the current remote directory :

Exit : If you want to exit from FTP then use this command

Get : Get a file from the FTP server

Lcd : Change the directory on the local machine

Ls : Same as dir

Mget ; Same as get, but you can use wildcards like “*”

Allow users to execute GET command on Server

Tue, 20 Jan 2009 13:08:23 +0000

If you want to allow few users who can fire get command on your server then you can do so easily using following steps, you can easily allow only selected/required users in particular group to run GET commands on your server :

First create a group on the server
]# groupadd getgrp
Now execute permission to group
]# chmod 750 /usr/bin/GET
Add this group to GET file.
]# chown root.getgrp /usr/bin/GET
To check the permission of GET
]# ll -ld /usr/bin/GET
If you want to add users to getgrp so that they can get execute permission on GET. Make sure getgrp should be secondary group of that user. For eg we will consider myuser1 as user for whom we want to grant permission.
]# gpasswd -M myuser1 getgrp
You need to check if the user is added
]# cat /etc/group | grep getgrp
For some reason if you want to add another user say myuser2 then make sure that you have to mention both myuser1 and myuser2 in your command as :
]# gpasswd -M myuser1,myuser2 getgrp
If you don’t mention both the user, this command will replace all the users with the user mentioned in your command. Its always recommended to run the cat command before adding any user so that you know how many users are already added. Or you can just edit the /etc/group file and add the user in the getgrp line.
Thus using above steps you can allow only root, myuser1 and myuser2 to execute GET command on your server and all other users will be denied for using GET command.

How to check server network speed.

Sat, 17 Jan 2009 07:32:13 +0000

Before placing order for server with any webhost, you should look what network speed you would be getting for your server. There are many ways to test network speed of your webhost. one of popular and widely used method is by pinging your server in MSDOS. You can also tracert it in MSDOS to see how many hops it takes to get from your computer to required server. You may ask your webhost to provide you download speed test.

Following instructions would help you to test network speed of your webhost :

Testing network speed is a measure on how fast can the data be delivered between the visitor and the host’s server. you can use Ping command on your Dos prompt so as to test network speed. You can easily test network speed by pinging the server. you just need to open MS-DOS prompt and fire a simple command: ping serverID, where server ID is either a domain name (e.g. C:\>ping yahoo.com), either an IP (e.g. C:\> ping 128.65.134.89).

Once you fire ping command you would be getting results similar to these:

Reply from 64.190.235.64: bytes=32 time=432ms TTL=45
Reply from 64.190.235.64: bytes=32 time=180ms TTL=45
Reply from 64.190.235.64: bytes=32 time=377ms TTL=46
Reply from 64.190.235.64: bytes=32 time=216ms TTL=45
Ping statistics for 64.190.235.64:
Packets: Sent=4 Received=4 Lost=0 (0% loss)
Approximate round trip times in milli-seconds:
Minimum = 180ms, Maximum = 432ms, Average = 301 ms

A ping time of under 200ms is very good, 200 to 400ms is average and 400ms and above are poor ping times. Make sure a poor ping times do not always indicate a problem or slow network. If you are pinging servers that are very far away (pinging a server located in USA from a computer located in Australia), then you may get poor ping times then normal even you have a good connection.The Loss % represents the percentage of packets (sent messages) that were “lost” (did not return within 1 second). High Lost packets are not good but few web hosts disable the Internet Control Message Protocol (ICMP), so pings are not responded. Usually webhost do this is to increase security for the server.

Another method for checking network speed you can use is Traceroute : This traces the route between the computer and the server. All information goes from your computer to the server, is passed through a few routers to get its destination. A traceroute will tell you how many routers are involved in between your computer and server and all information about the routers. You can fire this command at MS-DOS prompt as tracert serverID or domain name. C:\WINDOWS>tracert www.mysitespace.com
You would be getting results similar to these :

Tracing route to www.mysitespace.com [64.68.191.111] over a maximum of 30 hops:

1 119 ms 121 ms 120 ms sym0103723m01.bctel.net [207.102.1.251]
2 107 ms 114 ms 98 ms 207.102.34.249
3 113 ms 117 ms 123 ms 192.197.174.118
4 135 ms 122 ms 116 ms 166.48.13.245
5 134 ms 145 ms 159 ms core7.SanFrancisco.cw.net [204.70.4.93]
6 144 ms 142 ms 136 ms Hssi2-1-0.BR1.SCL1.Alter.Net [206.157.77.74]
7 145 ms 152 ms 147 ms 105.ATM3-0.XR1.SCL1.ALTER.NET [146.188.145.158]
8 138 ms 149 ms 146 ms 195.ATM2-0.TR1.SCL1.ALTER.NET [146.188.146.2]
9 189 ms 170 ms 209 ms 107.ATM6-0.TR1.NYC1.ALTER.NET [146.188.137.165]
10 187 ms 180 ms 180 ms 199.ATM7-0.XR1.BOS1.ALTER.NET [146.188.179.85]
11 194 ms 177 ms 185 ms 191.ATM8-0-0.GW1.BOS1.ALTER.NET [146.188.176.225]
12 196 ms 208 ms 179 ms NVC.customer.UU.NET [64.68.0.242]
13 197 ms 206 ms 207 ms www.mysitespace.com [64.68.191.111]

The numbers on the left are the so-called “hops”. The number of hops that it takes to transmit a packet of data from computer A to computer B is the number of routers. In above example there are 13 hops. As you can see, each response line gives you the HOP #, the round trip times for the 3 packets that were sent and host information (IP address and/or host name). The roundtrip times for each hop are representative of the time it takes to go from the source to the host for that particular hop and back to the source. For better network speed you should have small number of hops. Thus you can consider Traceroute as a good way to determine path of data transmission from your local machine to your server.

Download Speed Test File : You can ask your webhost to provide you with test download file using which you can download at your local end can thus can test network speed of network. You should go with a host who has the capability of sending at least a few hundred kBytes/second but if you are on dial-up connection you’ll not be able to test this yourself. There are chances that webhost may try to fool you by providing you a test file located on a fast, empty server so that you can get best speed so its always suggested to contact some one who is using their services [ current user ] and ask him to post a test file on his account which you can download and can check speed. This download test file should be big enough so that you can see the speed and stability over time, you can think of getting 10-15MB file, also try to test this download file at pick hours when server might be busy. Most important point to be noted is that all results depend on location, ISP etc. you can request few forum members to check what speed they get for your download test file and if you get good response from them, you can surely go with your preferred webhost.

There are many online tools applications available on internet using which you can also check network speed but above commands are enough for you to get basic information.

Blocking IP addresses using .htaccess file
Manytime you need to block certain IP which is threatening your website/server or is trying to attack your server by creating load on it [ DDOS attack] then you can easily block such IPs using .htaccess file. Once you manage to get the IP address which is playing with your server then you just need to add it in deny list of htaccess file. All IPs which are listed in this list cant access your site anymore and thus you can protect your server from such attacks. All you have to do is to add IP in your htaccess file which is located at root directory by using following code.

order deny,allow
deny from IP address

You can add as many IP address as you want in this list. One thing to be noted that spammers/hackers can change their IP addresses very easily as most spammers work from their home PCs which are not static and may update very often. Thus is may be very difficult for you to get exact IP address which you need to block. So its always better to get a good firewall for your server or a webhost who will manage your dedicated server for such security issues and will monitor it round the clock.
