Hi,
I have the CMS module on my 6509 with sup1/msfc2. My problem is easy:
all works (http, smtp, pop3, ...), except ftp.
a easy example:
I have a server on ipA. And I want to load balance ipB to ipA.
I connect to ipA to ftp service (ftp works):
# ncftp ipA
ncftp / > ls -al
[...]
ncftp / > pas
passive off
ncftp / > ls -al
[...]
ncftp / > pas
passive on
ncftp / > ls -al
[...]
So, it works.
Now I want to use CMS to load balance ipB to ipA:
# ssh root@ipA
# ifconfig lo:0 ipB netmask 255.255.255.255
then:
# conf t
module ContentSwitchingModule 3
vlan XXX client
ip address ipC 255.255.255.0
vlan YYY server
ip address ipD 255.255.255.0
probe ICMP icmp
interval 30
retries 2
failed 60
receive 20
serverfarm TEST_WWW
no nat server
no nat client
real ipA
inservice
probe ICMP
vserver TEST_WWW
virtual ipB any
serverfarm TEST_WWW
persistent rebalance
inservice
end
I can ping ipB, I can use http, smtp, pop3 on ipB but:
# ncftp ipB
ncftp / > pas
passive on
ncftp / > ls -al
[...]
ncftp / > pas
passive off
ncftp / > ls
List failed.
I have no firewall.
Worst:
conf t
mod con 3
vserver TEST_WWW
no in
virtual ipB tcp ftp service ftp
in
and now, nothing works !
# ncftp ipB
NcFTP 3.1.5 (Oct 13, 2002) by Mike Gleason (ncftp@ncftp.com).
Connecting to ipB...
# telnet ipB 21
Trying ipB...
Connected to ipB.
Escape character is '^]'.
^]
telnet> q
Connection closed.
#
Any idea ?
Thanks in advance
