Unable to connect to a server from our AIX server via FTP
Hi guys,
We are trying to connect to an FTP server from our AIX server. Getting the following message
Code:
# ftp 164.52.194.12
ftp: connect: A remote host did not respond within the timeout period.
ftp> open 164.52.194.12
ftp: connect: A remote host did not respond within the timeout period.
ftp>
However, we are able to reach out to the same server from our local PC (workstation) via powershell
Windows PowerShell

## Internet server configuration database
##
## Services can be added and deleted by deleting or inserting a
## comment character (ie. #) at the beginning of a line If inetd
## is running under SRC control then the "refresh -s inetd" command
## needs to be executed for inetd to re-read the inetd.conf file.
##
## NOTE: The TCP/IP servers do not require SRC and may be started
## by invoking the service directly (i.e. /etc/inetd). If inetd
## has been invoked directly, after modifying this file, send a
## hangup signal, SIGHUP to inetd (ie. kill -1 "pid_of_inetd").
##
## NOTE: The services with socket type of "sunrpc_tcp" and "sunrpc_udp"
## require that the portmap daemon be running.
## Also please use ## to designate comments in this file so that
## the smit commands can edit this file correctly.

## NOTE: When using IPv6 services, specify "tcp6" or "udp6" for the
## protocol. "tcp" and "udp" are interpreted as IPv4.

Upon checking the firewall status , we are getting the following message

Can not open device /dev/ipsec4_filt.
Please suggest what approach to take /checks to do in order to connect via FTP? Any specific firewall related checks we need to do ?
