. There is no information to provide any clue as to whether the PC or the server is at fault. I would suggest packet capture. On a Windows system, I suggest wireshark. The same for the server, if it is yours. If the server is Unix and you have access to do so, just simple tcpdump will work well. -- R. Kevin Oberman

Re: Does anyone have DNSSEC problem with uscg.mil

2013-11-14 Thread Kevin Oberman
Don't forget that Google will white-list domains with known (by them) broken DNSSEC and reply even though validation is broken, so using 8.8.8.8 for checking on whether validation is broken is not the best idea. -- R. Kevin Oberman, Network Engineer E-mail: rkober...@gmail.com

is the ncache time. One day is very, very long. Times like 1 minute are more appropriate, but again, this is a maximum, so the large value may not be an issue. Sorry. -- R. Kevin Oberman, Network Engineer, Retired E-mail: rkober...@gmail.com ___ Please visit

Re: Master to Slave initial zone transfer question

2014-04-16 Thread Kevin Oberman
add the new zone to the slave's configuration (usually named.conf)? I assume so, or it would never load. But named.conf is only read when named is started or a 'reload' command is sent to it (rndc reload). Until then, hte slave has no way of knowing that the zone was added. -- R. Kevin Oberman

Re: still have named memory leak

. The standard tool for this on FreeBSD is fetch(1). E.g. fetch -o FILE URL In a script I usually also use '-q' to eliminate noise, but YMMV. I suspect most systems have wget and/or curl installed, but fetch is always present on FreeBSD. -- R. Kevin Oberman, Network Engineer, Retired E-mail: rkober

Re: SRV records etc

in testing, so we considered it useful and happily supported it. :-) SRV records are almost essential for some applications. I can't imagine not supporting them. HINFO is getting pretty rare. The security issues are pretty obvious and its advantages are rather limited. -- Kevin Oberman

no longer have access to the trivial script since I retired. It's really harder than it looks to do right and I don't think my code was adequately rigorous, but was capable of responding to most issues. I'm sure more heuristics really needed to be added. -- Kevin Oberman, Network Engineer, Retired E
