Does the above line sets any limit on ftp logins because when i enabled this many users are complaining that they are not able to login.

Please help and suggest ... Should I increase that value 10

It already writes in the ftpaccess exapmle file:

# Limit: The limit clause is used to restrict the number of
# concurrent connections that the ftp server will allow. If
# the number of active connections reaches the configured
# limit, then the next connection request from an ftp client
# will be refused and the contents of the message file
# (e.g. /etc/msgs/msg.dead) will be sent as a notification
# to the ftp client. See ftpaccess(4).

# NOTE: The message file must be a valid file if this clause
# is used. If the file does not exist, then a blank message
# will be notified to the ftp client.

# limit all 10 Any /etc/msgs/msg.dead

Hello Raiden,

The limit line is more complex.
Your are able to limit the ftp access for different classes.
Classes are group of ip or hostname list.
In place to limit globally the access to your ftp server, you can give access limit for each classes on specific day with message or not.

For example, consider 2 classes :
class ftp_1 subnet_1
class ftp_2 subnet_2
limit ftp_1 0 SaSu
limit ftp_1 5 MoFr
limit ftp_2 10 MoFr0800-1730

This doens't open session for subnet_1 people on Saturday and Sunday. During working days subnet_1 can open max 5 sessions at any time.
For subnet_2 people, max 10 sessions can be open at same time on working days between 08:00 and 17:30.
With this manner you can serve both subnets.

There are a lot of possibilities ! Look also at man page for ftpaccess rule priorities.

You can see connection status with commands ftpcount and ftpwho. This last command has another output under HP-UX 11.31 and other release. An escalation is open by HP to correct this problem.

Regards,
Roland

Hello Raiden,

You can comment the line in ftpaccess with a # character in front of the line and look up the number of connection with ftpcount or ftpwho. No limit line int the file means no limit for connextion.
