Dotaz: apcupsd a ovladani jineho PC

[Fefe]

Ahoj, umi apcupsd ovladat i jina pc, na ups el. pripojena? Myslim tim, ze seriovy kabel mam do jednoho PC, ktere bude schopne korektne ukoncit i jiny PC na UPS.

Odpovědi

[oron]

ano, na druhom pc nastavis (je to popisane v apcupsd.conf):

UPSTYPE net
DEVICE IP_PC_s_UPS_cez_serial:3551

potom po zadani apcuspd status by si mal vidiet:

MASTER   : IP_PC_s_UPS_cez_serial:3551
STATUS   : ONLINE SLAVE

neblokovat port 3551 ...

[Fefe]

No jo, diky. Nejak jsem to prehledl. Jinak ted nastavuju prvni server a mam problem, nebo to nejak nechapu. Edituju soubor /etc/apcupsd.conf a nastavil jsem nisport na 3557 (puvodne 7000). Pak apcupsd restartuju a vypnu, abych mohl spustit apcaccess status a vypise mi to tuhle chybu:

APCACCESS FATAL ERROR in apcaccess.c at line 336
tcp_open: cannot connect to server localhost on port 7000.
ERR=Connection refused

. Jakto, jakoby to nebralo vubec v potaz ten config.

Spusti to cez strace -e open apcaccess status a uvidis skade to taha cislo portu.

[Fefe]

Moc moudry z toho nejsem:

open("/etc/ld.so.cache", O_RDONLY)      = 3
open("/lib/libwrap.so.0", O_RDONLY)     = 3
open("/lib/i686/cmov/libc.so.6", O_RDONLY) = 3
open("/lib/i686/cmov/libnsl.so.1", O_RDONLY) = 3
open("/etc/resolv.conf", O_RDONLY)      = 3
open("/etc/nsswitch.conf", O_RDONLY)    = 3
open("/etc/ld.so.cache", O_RDONLY)      = 3
open("/lib/i686/cmov/libnss_files.so.2", O_RDONLY) = 3
open("/etc/host.conf", O_RDONLY)        = 3
open("/etc/hosts", O_RDONLY|O_CLOEXEC)  = 3

[Semo]

No, mas dokaz, ze tvrdenie: jakoby to nebralo vubec v potaz ten config, je spravne.

[Fefe]

Divne, nechapu to. Mam zakladni instalaci s balicku. Tak odkud to teda bere?

[dustin]

Stačí se podívat do triviálního zdrojáku apcaccess.c a formát spouštění je jasný:

apcaccess status localhost:3557

[Fefe]

No me spis jde o tom, k cemu pak je ten konfigurak v /etc ?

[dustin]

Je to konfig pro démona, proto má to "d" na konci :)

apcaccess je klient, který se k démonovi připojuje. Konfig pro démona nečte, potřebuje jenom host:port.

[Fefe]

No tak jinak jak donutim, aby apcaccess klient komunikoval s demonem a bral si od nej nastaveni? Aby ten demon splnoval svou funkci.

[Sten]

Pokud jde o ovládání druhého PC, na obou bude spuštěný démon, který se o to už postará. Klient je jenom pro vás, když se chcete dotazovat, v jakém je to stavu.

[Fefe]

Me jde ted v tuhle chvili o to, abych mohl vubec tu UPS nejak nakonfigurovat. A to se mi nedari. Viz. ten error.

ale pomoci apctest se k UPS zrejme pripojim:

ale tohle nefunguje:

[Jiří Lisický]

apcaccess status
APCACCESS FATAL ERROR in apcaccess.c at line 336
tcp_open: cannot connect to server localhost on port 7000.

apcupsd je v tuto chvili vyply

No jak psal kolega výše: apcaccess komunikuje s apcupsd, takže je jasné že to napíše že se nemůže připojit.

[oron]

ak chces spusit apcaccess status task apcupsd musi bezat (chvilu treba pockat kym to nabehne a da vypis)
pre konfiguraciu UPS cez apctest - apcupsd nesmie bezat, da error ...

[Fefe]

-- chvilu treba pockat kym to nabehne a da vypis

To bylo ono.. stacilo pockat
