It is available at : http://www.g6ftpserver.com/?page=download

1) Download latest version from : http://www.g6ftpserver.com/?page=download
2) Backup your current installation to a safe place (copy whole directory)
3) Install the new version over the previous one.

Click on the domain, select users folder in the treeview, right click and select "new", a new window will popup prompting for the account name.

Create a new account (see previous question) with name "Anonymous", in this account disable password checking or select "Accept e-mail address" as password type.

Users & groups account are saved to [install path]/domain/accounts/users/ and [install path]/domain/accounts/groups/, domain settings are saved in [install path]/domain/.
To backup your users (for a reinstallation), copy the entire [install path]/Accounts/ directory to a safe place, when you reinstall the application copy this directory back to the new installed directory.

You have different possibilities :
1) Domain properties / Messages.
2) User account / Miscellaneous / Message Files.

You can customize your message (Login, change dir messages) with tags (macros), see manual :
http://www.g6ftpserver.com/manuals/en/

Note: some tags are not available before the user is authenticated.

In user account / Access rights, click on Add (+), enter a virtual path, a physical path then setup rights.
The first folder needs to be defined as '/'.

Resuming download is automatic, server always authorized it if you give "Read" access to the directory.
(you can see user is resuming by looking at the log :
REST xxx (>0)
350 REST supported. Ready to resume at byte offset xxx.
RETR filename )

Resuming upload needs to be enabled in directory access : "Append" option
(you can see user is resuming upload by looking at the log :
REST xxx (>0)
350 REST supported. Ready to resume at byte offset xxx.
STOR filename

OR

APPE filename )

To be able to change your password when connected to the ftp server, you first need to have option "Can change his password" enabled in user account / miscellaneous.
When connected send the raw command (see the ftp client help for more information about sending raw commands) :
SITE PSWD myoldpassword mynewpassword

If you are using a command line driven ftp client like ftp.exe :
QUOTE SITE PSWD myoldpassword mynewpassword

To email in case of successful upload (or any other events) you will need a command line emailer, like Blat for example, you can get it from : http://www.blat.net/194/ (public domain software)
Latest version link is : http://www.interlog.com/~tcharron/blat194.zip

In OnFileUploaded event, enter :

c:\pathtoscript\mailscript.bat $USR_IP "$USR_NAME" "$USR_FILE" $TIME "$DATE"

create mailscript.bat and put in :

rem create status file
echo User from IP : %1 > c:\pathtoscript\status.txt
echo Using account : %2 >> c:\pathtoscript\status.txt
echo Uploaded file : %3 >> c:\pathtoscript\status.txt
echo At : %4 - %5 >> c:\pathtoscript\status.txt

rem send the email
c:\pathtoblat\Blat.exe c:\pathtoscript\status.txt -to
youremail@yourdomain.com -subject "[FTP Server] upload status" -server
smtp.yourdomain.com -port 25
exit

You have to setup parameters (smtp.yourdomain.com ..) with yours and the script may need some changes to fit your exact needs.

Of course you can add more information by using a additional tags :
http://www.g6ftpserver.com/manuals/en/tags.html#Tagsandcustomization.1

Dos command line help :

Available IP are reported in FTP Server / Status. If you are creating a domain, available IP are listed in IP binding when you add an IP.

Also check http://www.g6ftpserver.com/ip.php to know which IP you are using to browse this FAQ.

First, it is not a software problem. There are 2 things you can do :
1) Contact your ISP to know if it is possible to have a fixed ip (maybe switch to cable).
2) Register a subdomain name on dynamic dns service (Selected are free).
For example you can get a name like : yourname.dyndns.org always pointing to your ip, in case the ip changes
you can update your ip on the site, either using a client or on the website.

See :

To allow the ftp server to receive ftp requests behind a firewall you need to open the port 21 (allow incoming) & 20 (allow outgoing) on the firewall, as well as the passive port range (allow incoming, see domain / IP binding / passive port range).
If you do not use default ftp port, you need to open main port (allow incoming), main port -1 (allow outgoing) & passive port range (allow incoming).

Popular firewalls settings :
Zonelabs ZoneAlarm : let the ftp server full access to internet (in & out).
Blackice : http://advice.networkice.com/Advice/Support/KB/q000012/default.htm
Windows XP Firewall : http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q308127

You need to forward requests from the router on port 21 (or the port you use) to the computer ip running G6FTP Server (192.168.0.1 in this case).
Also don't forget to open ports 21 (allow incoming) & 20 (allow outgoing) (main port & main port - 1) on router firewall (if builtin) so that people can connect.
All this should be explained in the router documentation, keywords are "port mapping, forwarding"


You can imagine an FTP server (port 21, ip 192.168.0.1) or http server(port 80, ip 192.168.0.2) running on lan behind the router :

 _______________________________________________________

port 80 => requests redirected to ip 192.168.0.2 => Computer 

running HTTP Server

         |

         V

         |

     Local Lan (192.168.0.*)

         |

         ------>----- Computer with ip 192.168.0.1

         |            (Running G6FTP Server on port 21)

         V

         |

         ------>----- Computer with ip 192.168.0.2

                      (Running http server on port 80)

When running the ftp server behind a router, the ftp server can only use local ip (10.0.xxx.yyy, 192.168.0.xxx ...) assigned to your computer.
This causes problems when a client switches to passive mode (PASV) because the ftp server will reply with the internal lan ip; as a consequence the ftp client can not transfer data (no directory listing, no upload / downloads, only commands).

To solve this problem :
1) in server option : domain / properties / IP binding, setup the Redirect Passive IP, you can enter a domain name or IP so that the ftp server knows your public IP.
2) enter a passive port range 50000-50100 in passive port range option.
3) in your router (hardware or software) create a port range redirection for 50000-50100 to the computer ip running the ftp server.

The ftp server will now use the external ip for passive mode and the router will correctly redirect passive connection thanks to the passsive port range option.

See server option : domain / properties / IP binding & enter the passive port range in the proper area.

An FTP Server uses 2 ports :
- main port (usually 21) for command (USER, PASS, CWD ...)
- data port (main port - 1) for data transfert (directory listing, upload & download)

The difference between Passive mode (PASV) and normal mode (PORT) is the connection :

- when using PASV, client asks server where it (the client) will have to connect to to establish data transfer link.

Client > PASV
Server > 227 Entering Passive Mode (209,15,39,184,249,155)

Ftp client must connect to 209.15.39.184 on port 249*256 + 155 = 63899

- when using PORT, client specifies what ip and port the FTP server must connect to to establish data transfer link :

Client > PORT 192,168,0,10,5,114
Server > 200 PORT command successful.

This time, it is the FTP server which connects to the FTP client (ip = 192.168.0.10 on port 5*256+114 = 1394)

PASV : client connects to server for data transfer
PORT : server connects to client for data transfer

more information : http://slacksite.com/other/ftp.html

The syntax to use in the URL box is :

ftp://login:password@yourserverip:port/[path/file.zip]

You need to enable option : Tools / Internet Options / Advanced / Browsing / Use PASV mode.

You need to disable option : Tools / Internet Options / Advanced / Browsing / Use PASV mode.

Default ftp.exe command line client bundled with Windows does not support passive (PASV) mode.

If you want a ftp.exe command line that supports passive mode, try :
ftp://ftp.gnu.org/gnu/windows/emacs/contrib/ftp-for-win32.zip

To connect to your ftp server from your lan by using your domain name (ftp.mydomain.com) instead of the local ip (192.168.0.xxx), add an entry in your windows host file :

- WinNT/2000 : c:\WINNT\system32\drivers\etc\hosts
- 9x/Me : c:\windows\system\hosts

You should already have an entry with :
127.0.0.1 localhost

Add the ip of the ftp server and your domain name like this :
192.168.0.1 ftp.mydomain.com

You can now connect to ftp.mydomain.com from your lan.

(you need to do this for all computers on your lan that you want to connect from).

Let's say you have a DSL connection with 512kbps down and 128kbps upload speed, G6FTP Server will report speed of 15-16KBytes/s in upload and 64KBytes/s in download. Why aren't the speed 512 & 128 ?

G6FTP Server reports speed in KBytes/s, not Kbits/s. To convert from KBytes/s to Kbits/s you need to multiply the speed in KBytes/s by 8, to convert Kbits/s to KBytes/s, divide by 8.
So 128 Kbit/s / 8 = 16KBytes/s, same for download : 512 / 8 = 64 KBytes/s.

Note that people downloading from you will use your upload speed (uploading will mean downloading for you), as most of the time speed is assymetric (upload < download speed) it is normal that you get lower upload speed.
Also internet speed are not guaranteed by your isp, so slow speed can be due to internet congestion (in that case you should contact your isp).

FXP, or server to server transfer is defined in RFC959 :

         User C <-> Server A                User C <-> Server B

         ------------------                ------------------

         

         C->A : Connect                    C->B : Connect

         C->A : PASV

         A->C : 227 Entering Passive Mode. A1,A2,A3,A4,a1,a2

                                           C->B : PORT A1,A2,A3,A4,a1,a2

                                           B->C : 200 Okay

         C->A : STOR                       C->B : RETR

                    B->A : Connect to HOST-A, PORT-a

1) If you are running Windows 2000 Server (and higher), make sure IIS FTP Service is disabled.
2) Make sure the port xx you defined for the ftp server is not already used by another application.
3) Try to change to another port number (domain / ip binding / port number), if the server can start on this different port, the previous port may already be in use by another application.

1) Make sure the server is online (check the FTP Server / logs which reports started domains).
2) Make sure you are giving your internet ip to your users, not a local ip.
3) If you are not using default ftp port (21), do not forget to specify it to your users.
4) If you are on a local lan, check faq G6FTP Server behind a router
5) If you use Windows XP, make sure builtin firewall (advanced network option) allow ftp server connection.
6) If everything has been checked and you still cannot have your users connect to your server, you may contact your isp to know if they allow you to run a ftp server (satellite connection are usually unable to host server)

1) If you are behind a router / firewall check FAQ : G6FTP Server behind a router
2) If remote user is behind a firewall, tell him to switch his ftp client to passive (PASV) mode
3) Check that this user have right to list (+List folder or files) in user account / access rights
4) FTP Client is behind a NAT, you should see a list attempt with PORT 192,168... command or PORT , user should switch his ftp client to PASV (passive) mode.

CHMOD is not supported with G6FTP Server, under windows you do not have to change file attributes via FTP (for CGI, scripts). The webserver often manages execute access right via CGI options.

The server administrator has entered a max value in domain / properties / Options / Max. number of clients.

The server administrator has entered a max value in domain / account / miscellaneous / Max. number of clients.

The server administrator has set a max connection value in domain / properties / Options / Max connections per IP.

You are not allowed to access the server, the administrator has added a restricted ip access list in domain / properties / IP access.

If you get this error after a USER/PASS, you are banned for this account, administration has added a restricted ip access list in domain / users / account / IP Access.

This error means the server is rejecting your login & password, possible reasons are :
1) you are not entering the login & password correclty, make sure they are entered as setup, passwords are case sensitive, logins are not.
2) you are not connecting to the correct IP for the domain, accounts will only be valid domain wide.

This error indicates that the home directory is either not set (no directory in the list) or invalid (directory does not exist, has been moved ...).

So to fix this problem you need to add or correct the first directory in your user account access rights list (listed as '/').

Also see :
http://www.g6ftpserver.com/manuals/en/

If you are running the server under "System" account and the home directory is a network share (drive), the server will not have access to it as "System" account has no access to network.
To fix this problem, you will have to create a new NT account, give it access to the shares and change the account used by the service to this new one.

For PORT command : this indicates you have supplied a port number < 1024 and setting : domain / properties / IP binding / allow connections to port < 1024 is disabled.

1) STOR means that the client wants to upload, so you need to give rights to write in user account access rights.

or

2) consider the following log :

(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > PWD
(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > 257 "/FTP" is current directory.

(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > PORT 10,0,0,1,16,92
(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > 200 Port command successful.
(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > STOR C:\FTP\TSTFILE.TXT
(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > asked to upload 'C:\FTP\TSTFILE.TXT' in 'C:\FTP\' --> Access denied.
(000001) 1/1/03 1:00:00 PM - USER (10.0.0.1) > 550 Cannot STOR. No permission.

The problem here is with the path sent by the ftp client which is not relative to home directory, whereas server sent a relative path in PWD command.
Solution is to check if it is possible that the ftp client sends relative path, the server does not accept physical path.

Some routers improperly changed the PASV command to P@SW which is not recognized by the ftp server.
You should contact the router manufacturer about this problem.

The first thing to check is that it is properly installed :

- Check that the port number to use is available, by default it is set to 80 but IIS (or another webserver) could be using it already, so change it in g6_webadmin.ini file :

#IP and port to use (*:80, *:443)
IP0=*,8080,
IP1=*,443,SSL

- Do not use the same port as for the Secure Remote administration, this will prevent Web Admin server to start (so do not choose 8021 as port number).
- Check that your firewall is not preventing access to the Web Administration port.
- Open your browser and type : http://127.0.0.1:[port]/ this should open the login page

If you receive something like : 200 1300 fx [..] then you are trying to connect on the Secure Remote Administration port which is not suited for Web Administration but for the Administration Client (G6FTPAdmin.exe) so check your port configuration.
