Yes, the ftpd service is active.

Code:
# lssrc -t ftp
Service       Command                  Description              Status
 ftp          /usr/sbin/ftpd           ftpd -d                  active
#

Windows PC and my AIX server are on the same LAN ,let's say LAN1

The server that i'm trying to connect to is on another LAN say LAN 2


I was successfully able to ping the AIX server from my local windows workstation

Here is the o/p:

Code:
C:\Users\LINC>ftp

Also, did you search the site first before asking this question?

I think this question has been asked and answered many times over the years.
Hi, i did search this site and went across 10-12 different posts/questions which were of similar nature,still haven't found a solution .

Yes, did do a traceroute from my host to the ftp server :

Code:
# traceroute 203.112.144.202
trying to get source for 203.112.144.202
source should be 172.16.80.80
traceroute to 203.112.144.202 (203.112.144.202) from 172.16.80.80 (172.16.80.80), 30 hops max
outgoing MTU = 1500
 1  172.16.80.100 (172.16.80.100)  31 ms  0 ms  0 ms
 2  172.16.80.100 (172.16.80.100)  0 ms !H * *
 3  172.16.80.100 (172.16.80.100)  0 ms !H * *
 4  172.16.80.100 (172.16.80.100)  0 ms !H *  0 ms !H
#

Thing is the infrastructure @ my organization where i joined 2 weeks back is a mess, no proper OS monitoring/maintenance was done for quite sometime . I immediately need to transfer important business docs from my SAP AIX server to ftp server.

Have checked the services file, ports,inetd.conf file. Tried checking the firewall status which led to this

Code:
# lsfilt -a
Can not open device /dev/ipsec4_filt.

Would be extremely grateful if you can guide me to look for areas where i can troubleshoot ?

Regards,
Bruno
