I am trying to bring multiple clients up using ipsec.conf from a single
machine. I can bring upto 50 connections up specifying a new connection in
(conn) section of
ipsec.conf on the client. everything works fine until I try load test on
these IP's. After a fixed number of packets I get an error "No Buffer space
I changed the sysctl settings to allot more buffer space for reading and
writing of tcp, but nothing works. During this time the management
interface has no issues.
Seems like the 50 tunnels I created max out on memory etc. I have to wait
for about 10 minutes and the connections
are back to normal or restart ipsec. Can you please advise what can be
Sample Config on the client
#Default for all the client connections
rightid="C=CH, O=strongSwan, CN=vpntest.x.com"
leftid="C=CH, O=strongSwan, CN=P2UJjggrNxA8Vcx_119a1d"
leftid="C=CH, O=strongSwan, CN=P2UJjhgrNxA8Vcx_119a1d"
