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 ( snipped-for-privacy@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 Marcelo
