Hi, I am trying to use nsupdate from knot 1.6.1. I have generated key files using dnssec-keygen from BIND 9.9.5. i.e. dnssec-keygen -a HMAC-MD5 -b 256 -n HOST -C host.example.com Whenever I try to use the files with nsupdate -k <file> though I get: ; Error: failed to read key file: public key file is invalid I have also tried without the “-C” to dnssec-keygen. Are there different flags I need? Or does someone have an example of the file format required? Thanks, Andrew

Short write?

by Linus Nordberg

Hi, I'm looking at knot-1.6.1 after have experienced failure with sending AXFR after a zone grew due to enabling DNSSEC, adding a lot of records. I don't know much about iovecs, but isn't this a short write? --8<---------------cut here---------------start------------->8--- libknot/internal/errcode.h: enum knot_error { ... KNOT_ECONNREFUSED = -ECONNREFUSED, ... KNOT_ERROR_MIN = -1000, ... KNOT_ERROR = KNOT_ERROR_MIN, ... KNOT_ECONN, ... }; libknot/internal/net.c: int tcp_send_msg(int fd, const uint8_t *msg, size_t msglen) { ... int total_len = iov[0].iov_len + iov[1].iov_len; int sent = writev(fd, iov, 2); if (sent != total_len) { return KNOT_ECONN; } ... } knot/server/tcp-handler.c: tcp_handle() { ... while (state & (NS_PROC_FULL|NS_PROC_FAIL)) { uint16_t tx_len = tx->iov_len; state = knot_process_out(tx->iov_base, &tx_len, &tcp->query_ctx); /* If it has response, send it. */ if (tx_len > 0) { if (tcp_send_msg(fd, tx->iov_base, tx_len) != tx_len) { ret = KNOT_ECONNREFUSED; break; } } } ... } --8<---------------cut here---------------end--------------->8--- Happy to file a bug report if that's a more proper way of reporting bugs.

[PATCH] Add "forced generic" dump style, and kdig +generic option

by Robert Edmonds

This patch adds a new "forced generic" dump style which dumps resource record types and data in the generic RFC 3597 representation format, even for known resource record types. A corresponding +generic option to kdig enables this dump style. Generic representation format is very handy when dealing with older DNS software that may not support a new resource record type, or with systems where it is more convenient to use the generic format even with known types. It is also a nice debugging / educational feature.

Statistics

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, does Knot have a feature like "rndc stats" in BIND or "nsd-control stats" that allows you to get some statistics about how many queries were handled and what their result were (like SERVFAIL etc.)?
