[15:59:14]  <marcelo-amaral>	hi
[16:01:21]  <marcelo-amaral>	I saw here: http://openvswitch.org/pipermail/discuss/2015-March/017097.html that OVS does not support yet modifying the type or code in ICMP. Is it still true?
[16:02:06]  <shettyg1>	marcelo-amaral: True.
[16:02:56]  <marcelo-amaral>	Is there any way to turn around this limitation?
[16:03:41]  <marcelo-amaral>	I want to create of rules for ICMP reply
[16:03:54]  <shettyg1>	Quick counter question. You want OVS to ICMP reply to you?
[16:04:36]  <shettyg1>	I suppose this is for L3 router interface?
[16:05:49]  <marcelo-amaral>	Yes, when we create a virtual router in openstack, the default gateway does not respond ping
[16:06:30]  <marcelo-amaral>	So, it is required to create a specific rule to deal with it
[16:11:28]  <marcelo-amaral>	shettygl: do you have any idea how I could create icmp reply? If it is possible
[16:24:03]  <marcelo-amaral>	blp: hi
[16:24:21]  <blp>	marcelo-amaral: hi
[16:25:54]  <marcelo-amaral>	blp: I am trying to create a icmp reply rule, but I saw that OVS does not support yet modifying the type or code in ICMP. Do you now, if there is a way to do it, or if ovs will support it?
[16:30:12]  <blp>	marcelo-amaral: It would not be hard to add, so we'd probably accept a patch to do it.
[16:30:29]  <blp>	It would require some care in use, since a lot of ICMP types don't have compatible payloads.
[16:46:16]  <marcelo-amaral>	blp: thank you, I will try to take a look in the code.
[16:49:28]  <marcelo-amaral>	blp: could you please point in the code, where is it?
[16:49:50]  <blp>	marcelo-amaral: Where is what?
[16:50:33]  <marcelo-amaral>	blp: the logic that block modifying the type or code in ICMP
[16:50:46]  <jiuweigui>	Hi. Are there any good book about openvswitch or sdns that you'd recommend?
[16:51:35]  <blp>	marcelo-amaral: meta-flow.h, change access from read-only to read/write for those fields
[16:52:03]  <marcelo-amaral>	blp: perfect! thank you very much
