Dear FreeBSD people,
May I ask you an question about our ftp server's connection problem.=20
We use Wu-2.6.1 as ftp server, which is running on Freebsd 4.3.
The part of FTP setting (simple type) is like this in rc.firewall?
=20
#Allow access to our FTP
${fwcmd} add pass tcp from any to ${oip} 21 setup
#for passive FTP. we also need to allow for setups
#to ports in a high range (49152..65575), see ftpf(8)
${fwcmd} add pass tcp from any to ${oip} 49152- setup
This setting will allow ftp being accessed generally, but there is some =
minor problem.=20
1. I found when I am not choosing the passive mode to connect to ftp =
server from client side machine, the file transfer and conneciton is =
going much faster and smoothly.
2. But when I choose passive mode (which is defaul setting for ws-ftp =
Le), the transfer goes much slowers, and even you are connected to the =
ftp server, for excute each ftp (ls, upload, download, etc) command, the =
client side has to connect to a server's port (higher range one ) again, =
which sometime succeed, some time fail, so takes much longer time than =
the NON-passive mode way. I put a log file at attached for your =
reference.
Do you think the above situation is normal? In this case, the passive =
mode seems not really good when considering the tranfer speed. So how =
can we overcome the problem of EVERY TIME THE CLIENT SIDE HAS TO =
CONNECT TO A SERVER'S HIGH RANGE PORT FOR EACH COMMAND WHEN IS PASSIVE =
MODE?=20
Thank you very much
Jennifer
