I-VPN iyawa uma isikrini siba mnyama: ukukhiya, isikrini esivaliwe noma ukulala?
Iseshini ekhiyiwe, isikrini esimnyama kanye nomshini olele kuyizigameko ezintathu ezahlukene. Hlanganisa lezi ne-journalctl ngaphambi kokusola indlela ye-VPN yokugcina uxhumano.
Uma othile ethi i-VPN yafa ngesikhathi isikrini siba mnyama, umbuzo wokuqala owusizo ukuthi yisiphi kulezi zigameko ezintathu esenzeka ngempela: iseshini yavalwa, iphaneli yacishwa, noma umshini wonke walala. Lezi ziyizindlela ezihlukene kuma-timer ahlukene, futhi eyodwa kuphela yazo engavimbela ngokuphelele ukuhlelwa kwenqubo. Dabulisa izivivinyo ezingezansi ngokulandelana. Yima kwesokuqala esiphendula umbuzo, ngoba yonke isivivinyo esilandelayo siphendula okunye.
Isivivinyo sokuqala: hlukanisa ukukhiya nesikrini esivaliwe nokulala
Ukukhiya kushintsha ukuthi ubani ovunyelwe ukusebenzisa iseshini; i-compositor iyaqhubeka nokudweba, isitaki senethiwekhi siyaqhubeka nokusebenza futhi iklayenti le-VPN aliboni lutho. Ukuvalwa kwesikrini kucisha iphaneli ngemva kwesikhathi sokungenzi lutho futhi kushiya umshini uphapheme ngokuphelele. Ukulala kumisa ama-CPU, okusho ukuthi ayikho inqubo endaweni yomsebenzisi ehlelwayo, ngakho-ke ayikho isignali yokugcina uxhumano engaqalisa, kungakhathaliseki ukuthi isikhathi sifushane kangakanani.
| Event | What it stops | Can it kill the tunnel? |
|---|---|---|
| Session lock | Input to your session | No |
| Display blank | The panel | No |
| Suspend to RAM | CPU scheduling, hence every process | Yes, and silently |
| Hibernate | Everything, with state written to disk | Yes |
Yileso thebula yisizathu sokuthi «isikrini saba mnyama» akusona isifo. Ikhompyutha yetafula ehlelwe ukuthi icime ngemizuzu emihlanu futhi ilale ngemizuzu engamashumi amathathu izobonisa isikrini esimnyama ngomzuzu wesithupha ngethunjini elinempilo ngokuphelele. Ukwehluleka ngomzuzu wamashumi amathathu kungenye isigameko esinesinye isixazululo, futhi kokubili kubukeka kufana uma kubukwa kwelinye uhlangothi lwegumbi.
Isivivinyo sesibili: beka izigameko zamandla nenethiwekhi emugqeni owodwa wesikhathi
Funda ijenele lesikhathi esilinganiselwe esikhundleni sokuqalwa konke, futhi ufake kokubili umphathi wokungena nokumnikazi woxhumano:
journalctl -b -u systemd-logind -u NetworkManager --since "45 minutes ago"
systemd-inhibit --listUmyalo wokuqala ubonisa izicelo zokulala, ukuvuka kanye nokushintsha kwenethiwekhi okwalandela. Owesibili ubonisa ukuthi yini ebambe ukhiye ovimbayo okwamanje, okukutshela ukuthi kukhona yini okuvimbela ukulala ngamabomu nokuthi yiluphi uhlelo. Lungisa amagama amayunithi uma umnikazi woxhumano lwakho engeyena u-NetworkManager, futhi khumbula ukuthi ukufunda iyunithi yomunye umsebenzisi noma ijenele lesistimu kuncike kunqubomgomo yendawo.
Umugqa ongekho akusona isiphumo esibi. Uma ijenele leyunithi ekhethiwe lingabonakali ku-akhawunti yakho, ukungabikho kombhalo wokulala akufakazi lutho, futhi ukuphetha ngokuthi «ayizange ilale» kusihlungi esingenalutho yiyona ndlela abantu abachitha ngayo iviki belungisa isignali yokugcina uxhumano.
Isivivinyo sesithathu: uma ilalile, thatha isinqumo sokuthi bekuhloswe yini
Uma ukushintsha kokulala sekuvuliwe emugqeni wesikhathi, umbuzo ushintsha usuka kokuthi kungani i-VPN yephuka uya kokuthi umshini wawufanele ngempela ulale yini. Kumakhompyutha aphathwayo impendulo ivamise ukuba yebo, futhi ukunqanyulwa kwethunji kuwukuziphatha okulindelekile okufanele iklayenti ilulame kukho uma ivuka. Esiteshini somsebenzi okufanele sihlale sifinyeleleka, inqubomgomo yokulala yiyona efanele ishintshwe. Ukuthatha isinqumo sokuthi yimuphi kule mishini emibili obhekile kudinga umbuzo owodwa, futhi lowo akuwona umbuzo ijenele elingawuphendula esikhundleni sakho.
Yishintshe ngezilawuli eziyingxenye yeseshini ongene kuyo, noma ngendlela esekelwa umlawuli uma isidingo sikhulumela umshini wonke. Ukuhlela isethingi yomphathi wesibonisi ngesikhathi ungenile ngenye i-akhawunti akusona isenzo esifanayo futhi kuzobonakala sengathi kusebenzile kuze kuqale iseshini elandelayo. Ukucisha ngokuphelele ukuphathwa kwamandla kuyimpendulo yokuqala ebanzi edla impilo yebhethri futhi efihla umbuzo wangempela wenqubomgomo.
Isivivinyo sesine: uma sahlala siphapheme, bheka inethiwekhi neklayenti
Umshini ophapheme olahlekelwe ithunji lawo unenye yezindaba ezintathu: inethiwekhi yokufinyelela yawa, iklayenti le-VPN lama noma laqala kabusha, noma uhlangothi lweseva lwavumela ukuhlangana ukuthi kuphele ngesikhathi iklayenti liqhubeka likholelwa ukuthi lixhunyiwe. Qhathanisa izimpawu zesikhathi zesigameko sokuxhumana nesigameko sethunji, futhi ube nembayo ngokuthi yikuphi okwafika kuqala.
Bese uhlola indlela yokululama ngokwehlukile kuseshini yokuqala. Isicelo esisha ngethunji elibuyisiwe singaphumelela ngesikhathi iseshini yohlelo yesikhathi eside evulwe ngaphambi kokuphuka ihlała yephukile, ngoba uhlelo lubambe isokhethi endala noma ikheli eligciniwe. Leyo yinkinga yohlelo, akusona ubufakazi bokuthi ithunji alibuyanga.
Umbiko owusizo uqukethe ini
Bhala ukulandelana nezimpawu zesikhathi nabanikazi: ukuthi iseshini yavalwa nini, isikrini saba mnyama nini, ukuthi isicelo sokulala sarekhodwa yini, ukuthi uxhumano lwawa futhi lwabuya nini, ukuthi ithunji lashintsha isimo nini nokuthi uhlelo lwenze ini ngempela. Yonke into inomnikazi, ngakho-ke yonke into inganikezwa kumuntu ofanele esikhundleni sokuba ibe isikhalo esijwayelekile nge-Linux.
Uma kukhona umugqa ongenkho kuleyo, yilokho okufanele kukalwe ngokulandelayo hhayi okufanele kushintshwe ngokulandelayo. Umugqa wesikhathi onezikhala unikeza ulwazi oluningi kunokushintshwa kwesethingi okwenziwe ngokuqagela.
