How to increase a NAT table, for example for 300000 sessions? I have tried #ipf -D -T ipf_nattable_sz=10009,ipf_nattable_max=300000 -E but after this NAT hangup and doesn't work. $ uname -a SunOS router 5.11 11.1 sun4v sparc SUNW,Sun-Fire-T1000 On FreeBSD i recompile kernel with bigger values and it works fine, but in Solaris - i doesn't want to recompile kernel/ipf.

However I am not able to find any documentation or library itself for use. Please provide more info on libipmp.

The X8DTH-6F motherboard has dual GigE NIC powered by the Intel 82576 (kawela) chipset [attached by igb driver]. We've got S10u9 installed: $ uname -a SunOS r10.atl.efoldering.com 5.10 Generic_144489-06 i86pc i386 i86pc The symptoms are very similar to what was reported here: http://opensolaris.org/jive/thread.jspa?threadID=124411 Since the chipset is completely different in this case (igb instead of e1000g) I'm posting to a new thread. The system is under a constant incoming load between 40 Mbit/sec to 240 Mbit/sec. At random times (usually about once per day, sometimes twice per day, sometimes not at all), the system disappears off the network (it can't ping other systems, and other systems can't ping it) for between 60 seconds to up to 30 minutes, after which it will mysteriously appear on the network again all without intervention. We actually have both igb0 and igb1 interfaces wired with separate IP</pre> khoffman-9trlstd70hfR7s880joybQ< at >public.gmane.org 2011-09-14T04:35:11 http://comments.gmane.org/gmane.os.solaris.opensolaris.networking/14268 <pre>Hello, I am using snv171. I am often confused by its NWAM: all IP ports before net0, net1....., I am wondering how do I know which one is mother board NIC which I usually set as default access port? Also, how do I disable nwam and set NIC static IP address manually? I used to disable nwam and then set static IP manually. However, svcadm disable svc:/network/physical:nwam svcadm enable svc:/network/physical:default do not work on recent version of S11 x86, though they still work on Sparc. Any idea how to set static IP on recent S11 x86 release? Tom root&lt; at &gt;aryabhata:~# cat /etc/release Oracle Solaris 11 snv_171 X86 Copyright (c) 1983, 2011, Oracle and/or its affiliates.

The driver can not be installed. Even inbox driver from earlier version of OpenSolaris OS, snv155, also can not run: "WARNING: mac_register failed for port 0" I guess there are some modificaiton in header files and I need a rebuild. However, even after I download the latest ON bits yesterday, the new driver still unable to run. I think the ON bits files posted to OpenSolaris.org have not been updated.

Application I am using is netperf. 2) Will it not create any problem for OS like creating backpressure in its Queues because I keep getting mbufs even after indicating LINK_STATE_UNKOWN and I return those mbufs from xmit. All these packets may end up in OS Queues. 3) Is there any thing more to stop getting packets apart from doing LINK_STATE_UNKNOWN/DOWN.

On FreeBSD host system I have the following configuration: on physical interface I created vlan, connected it to bridge, created epair and added it end to bridge. In such way I can connect several jailed systems (VNET) to one vlan, providing one virtual interface to each jail. I'm trying to achieve this functionality on OpenIndiana system (oi_151) so that severals zones could be connected to one vlan with own vnic, but I didn't managed yet.

My first issue is how to effectively/easily generate such connection (3WHS + optionally some data segments + FIN with data) on the client side. Is there easier way than using raw sockets ? Secondly, and this is tied to the first question, is what can make TCP stack (primarily interested in client side) to emit FIN+data segment, both on Solaris and other systems.

Suppose after the specified linger timeout, some data still cannot be sent or some data has not been ack'ed by the peer. In this case, the close() will return an error as documented. But what do apps expect the underlying TCP connection will behave? AFAIK, there is no Solaris document which states what will happen to the underlying TCP connection. Do apps expect that the connection will be aborted after the timeout, the same behavior if a zero linger time is set? </pre> Kacheong Poon 2011-05-06T15:44:17 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.os.solaris.opensolaris.networking
