Hi Vijila,
There are five files used to hold FTP configuration information.
Check following files:
1./etc/ftpd/ftpaccess --> configuration file is the primary configuration file for defining how the ftpd daemon operates. It is not necessary to enable the ftpacess file inorder to run ftpd. The configuration files allow you to configure FTP features, such as the number of FTP login tries permitted, FTP banner displays, logging of incoming and outgoing file transfers, access permissions, use of regular expressions, etc.

2. /etc/ftpd/ftpconversions -->Defines options for compression/decompression and tar/untar operations

3./etc/ftpd/ftphosts -->Lets you allow/deny FTP account access according to source IP addresses and host names.

4./etc/ftpd/ftpusers --> Restricts FTP access for specified users. This file shows entries which dont have access for ftp.
deny ftp access to selected users.

5./etc/ftpd/ftpgroups -->The group password file for use with the SITE GROUP and SITE GPASS commands

Also check for :
2./etc/passwd --> anonymous ftp access

3.~/.netrc -->login information for ftp.The .netrc file contains login and initialization information used by the ftp autologin process .ftp autologin
allows users to ftp to other hosts.

Reshma

I would create an ftpaccess file if you don't already have one. This will help set up a standrard and if you wish to restrict ftp in the future.

Here is a example ftpaccess file.

class all real,guest,anonymous *

limit all 50 Any /etc/msgs/msg.dead

readme README* login
readme README* cwd=*

message /welcome.msg login
message .message cwd=*

compress yes all
tar yes all

log commands real
log transfers anonymous,real inbound,outbound

shutdown /etc/shutmsg

email user@hostname

But please read up on what each line is actually doing
Thanks

Hi,
depending on the answer to:
Is this happening to only one user ??

If it is just one user, that user must have been specified as not being allowed to connect.

If all users are hit, then it is a generic problem with the ftp setup.

Hi vijila,
As all this files are not available ..then just check
/var/adm/inetd.sec --> disallow & allow users network services
The /var/adm/inetd.sec file is a security file that inetd reads to determine which remote hosts are allowed access to the services on your host. The inetd.sec file is optional; you do not need it to run the Internet Services.

You can use either a text editor or SAM to edit the inetd.sec file. SAM (System Administration Manager) is Hewlett-Packard's windows-based user interface for performing system administration tasks. To run SAM, type sam at the HP-UX prompt. SAM has an extensive online help facility.

1.If the /var/adm/inetd.sec file does not exist on your host, copy /usr/newconfig/var/adm/inetd.sec to /var/adm/inetd.sec.
2. Create one line in inetd.sec for each service to which you want to restrict access. Do not create more than one line for any service.

3.Each line in the /var/adm/inetd.sec file has the following syntax:
service_name {allow} host_specifier [host_specifier...] {deny}

4.Make sure the /var/adm/inetd.sec file is owned by user root and group other, and make sure its permissions are set to 0444 (-r--r--r--).

Few examples:
login allow 10.
*shell deny vandal hun
tftp deny *

The first example allows access to rlogin from any IP address beginning with 10. The second example denies access to remsh and rcp from hosts vandal and hun. The third example denies everyone access to tftp.

NOTE:Only the services configured in /etc/inetd.conf can be configured in /var/adm/inetd.sec

Reshma

Hi Reshma,

there is no ftp related files in /etc/ftpd.
But that files in /usr/newconfig/var/adm is not configured. ie no entires related to ftp in that.
In /etc/inetd.conf file there is entry like:

ftp stream tcp nowait --root /usr/lbin/ftpd ftpd -l

Using one user we can do ftp. that user can remotely login to that server.

If u know anything more .
Please try to share.

Hi vijila,
As this line is there in inetd.conf means ftp service is enable.

See,The /etc/inetd.conf file is the inetd configuration file, which lists the services that may be started by inetd.

1.Make sure the following lines exist in /etc/inetd.conf. If any of the lines starts with a pound sign (#), remove the pound sign to enable the service.

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l
2.If you made any changes to /etc/inetd.conf, type the following command to force inetd to read its configuration file:

/usr/sbin/inetd -c
3.Make sure /etc/inetd.conf is owned by user root and group other, and make sure its permissions are set to 0444 (-r--r--r--)

Now still if it will not work, then just Restart the inetd daemon.

Reshma
