Solaris 10 ftp connection problem (connection refused, connection timed out)
Hi everyone,
I am hoping anyone of you could help me in this weird problem we have in 1 of our Solaris 10 servers. Lately, we have been having some ftp problems in this server. Though it can ping any server within the network, it seems that it can only ftp to a select few. For most servers, the ftp connection either times out or is rejected. All IP configurations in the server are correct, as verified by our network team. All system configurations on ftp seem to be working as shown below:
------------------------------------------------
root@SOL10SER # svcs -a | grep ftp
online 2:34:37 svc:/network/ftp:default
root@SOL10SER # inetadm | grep ftp
enabled online svc:/network/ftp:default
root@SOL10SER # cat /etc/services | grep ftp
ftp-data 20/tcp
ftp 21/tcp
tftp 69/udp
root@SOL10SER # netstat -an | grep *.21
*.21 *.* 0 0 49152 0 LISTEN
*.21 *.* 0 0 49152 0 LISTEN
-------------------------------------------------
As for the network part, we have verified that the following files contain correct values:
/etc/defaulrouter
/etc/netmasks
result of ifconfig -a
Furthermore, this server is not connected to any firewall/load balancer/proxy
Can anyone tell me what's going on? Thanks everyone for your time.

simpleftp
SIMPLEFTP(1) General Commands Manual SIMPLEFTP(1)
NAME
simpleftp - rudimentary ftp client
SYNOPSIS
simpleftp ftp://... [ ... ]
DESCRIPTION
simpleftp is a perl script that provides basic support for fetching files with FTP in a batch oriented fashion. It takes one or more ftp
URLS on the command line. The file(s) will be retrieved from the remote server and placed in the current directory with the same basename
as on the remote; i.e., ftp://ftp.isc.org/pub/usenet/CONFIG/active.gz is stored as active.gz in the current directory.
BUGS
simpleftp is an extremely poor substitute for more complete programs like the freely available wget or ncftp utilities. It was written
only to provide elementary support in INN for non-interactive fetching of the files in ftp://ftp.isc.org/pub/usenet/CONFIG/ without requir-
ing administrators to install yet another package. Its shortcomings as a general purpose program are too numerous to mention, but one that
stands out is that simpleftp does not understand the complete syntax of URLs, only the hostname and pathname parts -- it will not under-
stand username, password, port or parameter strings.
