Hi! all:
When I use IPVS via NAT like this :
ipvsadm -A -t 172.26.20.73:80
ipvsadm -a -t 172.26.20.73:80 -r 10.0.0.11:80 -m
The IPVS works well (the http connections from some client nodes
can be redirected to real server 10.0.0.11).
At the same time, the inetd service on VIP 172.26.20.73
are runnig normally. (for example: telnetd, ftpd)
But, if I set :
ipvsadm -A -t 172.26.20.73:21
ipvsadm -a -t 172.26.20.73:21 -r 10.0.0.11:21 -m
The IPVS works well (the ftp or telnet connections from some client
nodes \
can be redirected to real server 10.0.0.11).
At the same time, the inetd services on 172.26.20.73 are
failed!!(telnet,finger,...) \
I can not telnet to the VIP 172.26.20.73, neither telnet out from it(as
a telnet client), \
but 172.26.20.73 is still alive(ping works). it looks like the inetd
services are "jammed". \
After setting the command "ipvsadm -C", the jammed inetd services
will work normally again.
My system is running RedHat6.1 with kernel-2.2.14, and ipvs-0.9.11
patched. \
May someone give me some suggestions or resolutions, thank you very
much! \
