similar to: [Bug 1625] New: [PATCH] Make configuration of key verification from DNS easier

My apologies if I'm posting the wrong place, or am asking a common question. All my looking so far hasn't turned up anything very useful in knowing what to look at, or what to modify. --- CentOS 5, running BIND 9.3.6 i386 Hardware: P4, 2.8Ghz, 1G memory Sata drives - non mirrored etc. Load is light, usually under 0.1 -- This box is running Postfix as our mail server. BIND (9.3.6)

Has anyone had problems accessing random websites since going up to 6.4? Since about the day after I got partly upgraded, if I try to access nytimes.com, or orbitz.com, I get server not found. With a lot of work, I, my manager, and the other admin, found that setting options edns0 in /etc/resolv.conf fixed it - I suspect that the network folks updated their internal nameservers (which are M$)

For the member servers, to reduce timeouts etc when one DC is down. Change your resolv.conf to : domain internal.domain.tld search internal.domain.tld nameserver IP_DC1 nameserver IP_DC2 options timeout:2 options attempts:2 options rotate options edns0 see man resolv.conf for the options explained. Ow.. and .. domain and search are NOT exclusive anymore in Debian Jessie and up. At least,

Hello. I have an issue with SSHFP lookups using "VerifyHostKeyDNS=yes" and "options edns0" in /etc/resolv.conf (glib >= 2.6). getrrsetbyname() calls res_query() with a maximum buffer size of 65536. The glibc resolver truncates this value to 16 bits, reducing the query's advertised buffer size to 0. BIND appears to ignore it while Unbound returns a server failure.

So if this is done, is edns configure also ? ? in resolv.conf add: options edns0 ? and, name.conf test these. ? ??????? //?The forwarded zone to the AD-DC DNS use these also. ????????//dnssec-must-be-secure?internal.domain.tld no; ????????//dnssec-must-be-secure 168.192.in-addr.arpa no; ????????// listen-on-v6 { ::1; };? // test what works best, if not all?ipv6 is disabled also?enable this

Hai Ole, What does this give you as output? host bpn.tu-berlin.de I assum you dnsdomain name is the same as your REALM_NAME ? For me it show the 2 ipadresses of my DC's. And my MX record.

A few weeks ago, suddenly, reading news at lunch, I could not get to nytimes.com. I could ping it, and nslookup it, and if I put the IP address in place of the name, it was fine. After *much* back and forth over a ticket I put in, over the last week or so, our group figured it out: It *seemed* to be related to IPv6, and there's only *some* few sites, such as the Times, and Orbits, and one or

Hello All, I have a client-server setup with about 100 nodes. We often install the OS and this results in change of host keys in our server. This necessiates the need to update all known_hosts files in the client machines. Im using the VerifyHostKeyDNS option in the client side where the DNS is updated with new finger print each time we change the host key. But still the SSH client verifies

Hi all, Wish you a happy new year altogether! Mathias, James, let me first say that I highly appreciate your help with all your testing and writing up your thoughts. Here are my responses: A. I have no different sites, no various subnets; so I don't really know what to do. B. I don't understand the purpose of setting my domain up with different sites with associated networks, if on

Hello, I'm running Samba 4.9.5 as domain member, when I bring down the current Window DC (10.50.50.187) the winbind seems to hang instead of switching to the other available DC (10.50.50.25) The "net ads" command show that Samba switched to the other available DC: net ads join -U 'administrator' -S 'PAVONE.HYPERFILE.LOCAL' 'HYPERFILE.LOCAL'^C root at

Dear OpenSSH Developers, I'm a member of the Debian System Administration (DSA) team. [1] We manage the Debian Projects computing infrastructure. Recently, DSA had the opportunity to address a member's request that we begin using certificates to authenticate Debian Project machines to ssh clients. We provided a lengthy reply, the summary of which is "we publish SSHFP records; use

Hi, I submitted a patch back in November of 2009 to add local validation of DNSSEC record to openssh. I recent updated the patch for 5.8, and figured I do a little marketing while I'm at it. :-) Someone had previously submitted a patch which simply trusted the AD bit in the response, which is susceptible to spoofing by anyone who can inject packets between the resolver and the client. Our

Ok, I updated resolv.conf as you said. Then I restarted the network service on this member server and afterwords suspended the 1st DC.

Thanks Rowland, I have removed from options, and amended the forwarders. [global] workgroup = <MYDOMAIN> realm = <MYDOMAIN>.CORP netbios name = <HOSTNAME> server role = active directory domain controller idmap_ldb:use rfc2307 = yes idmap config * : range = 3000-7999 ----------> If I remove the portion I get errors -> idmap

Yes, it does for me, too. What is an mx record?
