RE: confused with if_baudrate

2011-11-19 Thread Hartmut.Brandt
Hi, the 64-bit statistics counters are also likely to be wrong, if the polling interval is too short (it is determined by the interface in the system with the highest baudrate). This can be fixed by setting begemotIfPoll to an appropriate value in bsnmp, though. harti _

Need help on IPv6 prefixes and interface addresses

2009-11-25 Thread Hartmut.Brandt
Hi all, I try to make bsnmpd IPv6 aware and need some help here. I've set up a small IPv6 network for testing between a couple of VMs. For IPv6 interface addresses there are two tables: ipAddressPrefix table and ipAddressTable (containing pointers to the prefix table). Now I see something on

RE: Need help on IPv6 prefixes and interface addresses

2009-11-25 Thread Hartmut.Brandt
To answer my own question :-) These strange link local addresses are explained in the developers handbook section 8.1.1.3 and are called embedded link local addresses. These are not standard IPv6 addresses, but a way to encode the interface index (aka zone index) into the IPv6 address. This must

Getting creation and modification time of an IPv6 interface address

2009-11-25 Thread Hartmut.Brandt
Hi, I'm working on the IpAddressTable for bsnmpd. This table has two rows ipAddressCreated and ipAddressLastUpdated which seem to correspond to the created and changed fields of the struct in6_ifaddr. Because there seems no way (except for poking in the kernel memory) to get at these values I h

TCP RST question

2009-07-31 Thread Hartmut.Brandt
Hi all, I'm looking at our TCP stack and found a change that was introduced with the syncache. The original BSD code did send an RST segment when the connection timed out in SYN-RECEIVED. The TCP would retransmit the SYN+ACK several times and then give up and RST the peer. With syncache, however,

Hi, there is a freebsd-atm mailing list (at least there used to be). Should have been sent there too. On the topic: I'd say: remove it. As the one who wrote/refactored much of that stuff I get approximately one support request per year. The problem is, that I can't really help, since while I h

AW: No SNMP ifHCInOctets counters for ipsec interfaces

2019-10-25 Thread Hartmut.Brandt
Hi, They used to be enabled only when the bit rate reported by the interface was high enough (there is some wording in the corresponding RFC when the HC counters are required and when not). This check was removed at some point - in 12.1 the Hc counters are unconditionally there. You may want to
