search for: edns0

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. glibc...

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, i didnt find it anymore.

...Component: ssh AssignedTo: unassigned-bugs at mindrot.org ReportedBy: vonsch at gmail.com Created an attachment (id=1665) --> (http://bugzilla.mindrot.org/attachment.cgi?id=1665) proposed patch Configuration of key verification from DNS currently requires "options edns0" in /etc/resolv.conf. Such requirement has two drawbacks: - every DNS request is the EDNS0 packet thus more bandwidth is consumed - "options edns0" in resolv.conf is really not intuitive Proposed patch makes verification working even if "options edns0" is not set.

...s timeout:1 Great, this sounds exactly as what I need! However, I tried this: no effect. I created this file and restarted the network service. But I still get long timeouts and can't login via ssh, when I suspend my 1st DC. # cat /etc/resolvconf/resolv.conf.d/tail options timeout:1 options edns0 Or do I need Network Manager for that? > options edns0 What's that for, particularly? > > timeout:n > sets the amount of time the resolver will wait > for a response from a remote name server before retrying the query > via a different name &g...

...g-eth0 and restarting the network, but another admin got it nailed, we *think*: apparently the M$-based DNS resolver's sending back extended DNS packets, and we gag. tcpdump saw us asking for an A record, then an AAAA record, then using search.... But putting the *very* counterintuitive option edns0 in /etc/resolv.conf, it works instantly, no caching, no nuthin'. Taking that out breaks it again. My question: it *appears* that we could add option edns0 to dhcpd.conf on the server, and it would fix it for everyone on our subnet. Have I misunderstood what I'm reading in the manpages?...

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$) about that time... but... we got this Thurs. Friday, I went to look, lunchtime, at a story, and back to the same. Later, and I think I was playing around, it came back. Just now, over...

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
