using mdnsd as resolver
hi all, i'm trying to use openmdns to find my network printer. it shows up (sporadically) when i run $ mdnsctl browse -r and i can obtain the address using $ mdnsctl lookup EPSON892A3E.local but how do i integrate the mdns daemon into resolv.conf? the man pages certainly don't mention how to do it. i would expect gethostbyname(3) to be able to resolve EPSON892A3E.local . -- cheers, björn

So given that there doesn't seem to be a stable way to extend the termcap database from a port, shouldn't it be depracated?

libedit history size required
hi all, i came across this little problem when using the edit library (https://github.com/openbsd/src/tree/master/lib/libedit): when using the history facility one needs to explicitly set a size, e.g., history(hist, , H_SETSIZE, 100); otherwise history will not work. the man page history(3) makes no mention of this fact. this leads me to three questions: 0. is this an oversight or by design? 1. shouldn't this requirement be documented? 2. shouldn't there be a reasonable default? if the answers to 1. or 2. are yes, i'd be willing to send patches. -- cheers, björn

hi all, i have this embarrassing little problem: when i play music and plug in head phones, the built in speakers are not muted, even though mixerctl says so. the headphones do work correctly. i get this output whith the head phones plugged: inputs.dac-2:3=80,80 inputs.dac-0:1=80,80 record.adc-0:1_mute=off record.adc-0:1=124,124 record.adc-2:3_mute=off record.adc-2:3=124,124 record.adc-4:5_mute=off record.adc-4:5=124,124 inputs.mic=85,85 outputs.spkr_source=dac-2:3 outputs.spkr_mute=on outputs.spkr_eapd=on inputs.mic2=85,85 outputs.mic2_dir=input-vr80 outputs.hp_source=dac-0:1 outputs.hp_mute=off outputs.hp_boost=off outputs.hp_eapd=on record.adc-4:5_source=mic2 record.adc-2:3_source=mic2,mic record.adc-0:1_source=mic outputs.mic2_sense=unplugged outputs.hp_sense=plugged outputs.spkr_muters=hp outputs.master=80,80 outputs.master.mute=off outputs.master.slaves=dac-2:3,dac-0:1,spkr,hp record.volume=124,124 record.volume.mute=off record.volume.slaves=adc-0:1,adc-2:3,adc-4:5 record.enable=sysctl doing a `mixerctl -t outputs.spkr_mute` separately toggles the variable, but has no audible effect, the speaker stays active either way. `mixerctl -t outputs.master.mute` (or pressing the built in mute button) does work, but obviously mutes the speaker as well as the headphones. dmesg says: azalia0 at pci0 dev 31 function 3 "Intel 100 Series HD Audio" rev 0x21: msi azalia0: codecs: Realtek ALC236, Intel/0x2809, using Realtek ALC236 audio0 at azalia0 the machine is a lenovo ideapad 500S. the device used to work correctly with linux. i'm running 6.8 GENERIC.MP#277 amd64. did i misconfigure anything, or could this be a bug? thanks in advance for any hints. -- cheers, björn

Curiously, what I observe with the RTL8192EU is that after associating, that value starts at 1 and as transmissions are made, moves to 54 in increasing steps, and then stays there. I guess that corroborates your point about incorrect information being returned by the device. Unfortunately I don't have another wifi adapter to test with. Anyway, thanks for your help, I'll give it a rest now. -- Cheers, Björn

Getting wifi bitrate
Hi all,
I have a small question: I want to get the current rate of actually
transmitted (and received) bits for my wifi adaptor. I thought this
fragment from ifconfig does what I want
(https://github.com/openbsd/src/blob/3a44e88910781e836bd51a8b6b068379abc67a1b/sbin/ifconfig/ifconfig.c#L2783):
if ((nr->nr_flags & (IEEE80211_NODEREQ_AP)) == 0) {
if (nr->nr_flags & IEEE80211_NODEREQ_VHT) {
printf("VHT-MCS%d/%dSS", nr->nr_txmcs, nr->nr_vht_ss);
} else if (nr->nr_flags & IEEE80211_NODEREQ_HT) {
printf("HT-MCS%d ", nr->nr_txmcs);
} else if (nr->nr_nrates) {
printf("%uM ",
(nr->nr_rates[nr->nr_txrate] & IEEE80211_RATE_VAL)
/ 2);
}
} else if (nr->nr_max_rxrate) {
printf("%uM HT ", nr->nr_max_rxrate);
} else if (nr->nr_rxmcs[0] != 0) {
for (i = IEEE80211_HT_NUM_MCS - 1;
i >= 0; i--) {
if (nr->nr_rxmcs[i / 8] & (1 << (i / 10)))
break;
}
printf("HT-MCS%d ", i);
} else if (nr->nr_nrates) {
printf("%uM ",
(nr->nr_rates[nr->nr_nrates - 1] &
IEEE80211_RATE_VAL) / 2);
}
But when I paste that into my application code and run it I get
"HT-MCS23". My best understanding is that this refers to some definition
of modulation coding schemes, i.e., not the bitrate I'm looking for.
So how do I get the it? Am I looking in the wrong place, or does the
driver just not expose this information?
The interface is a "Realtek Wireless N Nano USB Adapter" in case that is
relevant.
Cheers and a happy new year,
Björn
xterm dies
Hi All, Since updating to snapshot a few days ago I've been having problems with xterm randomly dying. I was able to capture this on another terminal: 16:51:12 bgohla@titanic[1] ~ $ xterm: Error 50, errno 35: Resource temporarily unavailable Reason: in_put: select() failed 16:51:12 bgohla@titanic[1] ~ $ man select [1]+ Exit 50 xterm sh 17:54:42 bgohla@titanic ~ $ This is very annoying (I even had to start this email over because of it). There don't seem to be any recent changes to xterm, so I'm out of ideas where to look for the source of the error. Any ideas what one can do in this situation? Would another sysupgrade -s help? Cheers, Björn
development best practices
hi all, i'm fairly new to openbsd. and i've run into the following problem, where i want to hack a project (most recently trying to fix a possible issue with i3status), but building the from the git source tree fails. now, in the specific case, i'm trying to build a version that, also exists in ports, so we know it can be built on openbsd; and i presume the various patches included with the port are what makes it work. i could of course try to apply those patches and fix my issue. but then when i submit a PR upstream i'd have to remove them again. that seems cumbersome, expecially if done repeatedly. so what is the best practice in this situation? should i just upstream the ports patches? thanks. -- cheers, björn
