Pl\u0101no\u0161ana<\/h3>\n

\nEso\u0161\u0101 servera da\u013ca lietot\u0101jiem bija uz Linux. Gandr\u012bz katr\u0101 organiz\u0101cij\u0101 ir Windows serveri, ko nevar teikt par Linux. Galven\u0101 Veliam stipr\u0101 puse ir att\u0101lin\u0101tie savienojumi ar serveriem un t\u012bkla apr\u012bkojumu aiz NAT. Bet \u0161\u012b funkcionalit\u0101te bija \u013coti stingri saist\u012bta ar to, ka mar\u0161rut\u0113t\u0101jam bija oblig\u0101ti j\u0101b\u016bt MikroTik. Un tas noteikti daudziem neapmierin\u0101ja. Es s\u0101kum\u0101 s\u0101ku dom\u0101t par atbalsta pievieno\u0161anu visizplat\u012bt\u0101kajiem mar\u0161rut\u0113t\u0101ju pieg\u0101d\u0101t\u0101jiem. Bet es sapratu, ka t\u0101 ir bezgal\u012bga sacens\u012bba ar atbalst\u012bto uz\u0146\u0113mumu saraksta papla\u0161in\u0101\u0161anu. Turkl\u0101t ar\u012b tiem, kurus jau atbalsta, var b\u016bt at\u0161\u0137ir\u012bgs komandu kopums NAT noteikumu main\u012b\u0161anai atkar\u012bb\u0101 no mode\u013ca. Vien\u012bgais izeja no situ\u0101cijas redz\u0113ja VPN. <\/p>\n

T\u0101 k\u0101 m\u0113s nol\u0113m\u0101m izplat\u012bt produktu, bet ne k\u0101 open source, vairs nebija iesp\u0113jams iek\u013caut sav\u0101 sast\u0101v\u0101 da\u017e\u0101das bibliot\u0113kas ar atv\u0113rt\u0101m licen\u010du veidam GPL. Tas ir pavisam atsevi\u0161\u0137s temats, p\u0113c l\u0113muma par produkta p\u0101rdo\u0161anu bija j\u0101p\u0101rskata puse no bibliot\u0113k\u0101m, jo t\u0101s bija GPL. Kad rakst\u012bj\u0101m sev, tas bija norm\u0101li. Bet izplat\u012b\u0161anai tas neder. Pirmais VPN, kas n\u0101k pr\u0101t\u0101, ir OpenVPN. Bet tas ir GPL. V\u0113l bija iesp\u0113ja izmantot Jap\u0101\u0146u SoftEther VPN. T\u0101s licence \u013c\u0101va iek\u013caut to sav\u0101 produkt\u0101. P\u0113c p\u0101ris dien\u0101m da\u017e\u0101du testu, k\u0101 to integr\u0113t t\u0101, lai lietot\u0101jam visp\u0101r nekas neb\u016btu j\u0101konfigur\u0113 un j\u0101zina par SoftEther VPN, m\u0113s izveidoj\u0101m prototipu. Viss bija k\u0101 vajag. Bet, kaut k\u0101 m\u0113s \u0161aj\u0101 sh\u0113m\u0101 tom\u0113r vilcin\u0101j\u0101mies, un galu gal\u0101 no t\u0101s atteic\u0101mies. Bet, protams, atteic\u0101mies p\u0113c tam, kad izdom\u0101j\u0101m citu variantu. Galu gal\u0101 viss tika izdar\u012bts uz parastajiem TCP savienojumiem. Da\u013ca savienojumu darbojas caur koordin\u0101toru, da\u013ca tie\u0161i caur tehnolo\u0123iju Nat Hole Punching (NHP), kas ar\u012b tika realiz\u0113ta uz Free Pascal. J\u0101teic, ka par NHP es agr\u0101k visp\u0101r nebiju dzird\u0113jis. Un nemaz nevar\u0113ja ien\u0101kt pr\u0101t\u0101, ka var tie\u0161i savienot 2 t\u012bkla ier\u012bces, abas no kur\u0101m atrodas aiz NAT. Izlas\u012bju t\u0113mu, sapratu darba principu un s\u0101ku rakst\u012bt. Pl\u0101notais tika \u012bstenots, lietot\u0101js savienojas ar vienu klik\u0161\u0137i ar nepiecie\u0161amo ier\u012bci aiz NAT pa RDP, SSH vai Winbox bez parol\u0113m un VPN konfigur\u0101cijas. Turkl\u0101t liel\u0101k\u0101 da\u013ca \u0161o savienojumu iet gar\u0101m m\u016bsu koordin\u0101toram, kas pozit\u012bvi ietekm\u0113 ping un \u0161o savienojumu apkalpo\u0161anas izmaksas.<\/p>\n

Servera da\u013cas p\u0101reja no Linux uz Windows<\/h3>\n

\nP\u0101rejot uz Windows, bija vair\u0101kas probl\u0113mas. Pirm\u0101 \u2014 ieb\u016bv\u0113tais wmic Windows ne\u013cauj veikt WQL piepras\u012bjumus. Bet m\u016bsu sist\u0113m\u0101 jau viss bija izveidots uz tiem. Un bija v\u0113l kaut kas, bet \u0161obr\u012bd neatceros, k\u0101d\u0113\u013c galu gal\u0101 atteic\u0101mies no t\u0101 izmanto\u0161anas. Iesp\u0113jams, at\u0161\u0137ir\u012bbas starp Windows versij\u0101m. Un otr\u0101 probl\u0113ma \u2014 daudzk\u0101rt\u012bba. Neatradu labu tre\u0161o pu\u0161u util\u012btu ar mums pie\u0146emamu licenci, t\u0101p\u0113c es atkal atv\u0113ru IDE Lazarus. Un uzrakst\u012bju nepiecie\u0161amo util\u012btu. Ievedum\u0101 tiek ievad\u012bts vajadz\u012bgais objektu saraksts un kuru tie\u0161i piepras\u012bjumu nepiecie\u0161ams veikt, bet atbilde ir dati. Un viss tas notiek daudzk\u0101rt\u012bbas re\u017e\u012bm\u0101. Lieliski.<\/p>\n

P\u0113c tam, kad konfigur\u0113ju pthreads PHP Windows, dom\u0101ju, ka viss darbosies, bet t\u0101 nebija. P\u0113c k\u0101da laika atk\u013c\u016bdo\u0161anas sapratu, ka pthreads it k\u0101 str\u0101d\u0101, bet tie\u0161i m\u016bsu sist\u0113m\u0101 tas nedarboj\u0101s. Skaidrs, ka ir k\u0101da \u012bpa\u0161a iez\u012bme pthreads darb\u012bb\u0101 Windows. T\u0101 ar\u012b bija. Izlas\u012bju dokument\u0101ciju, un tur bija rakst\u012bts, ka Windows skaits pavedienu ir ierobe\u017eots, turkl\u0101t, cik atceros, tas bija neizteikts. Tas k\u013cuva par probl\u0113mu. Jo, kad s\u0101ku samazin\u0101t paveidu skaitu, pie kura programma str\u0101d\u0101ja, t\u0101 str\u0101d\u0101ja \u013coti l\u0113ni. Atkal atv\u0113ru IDE, un tai pa\u0161ai util\u012btai tika pievienota daudzu pavedienu pingo\u0161anas objekti. Un v\u0113l kl\u0101t ar\u012b portu skan\u0113\u0161ana. Patiess, p\u0113c tam nepiecie\u0161am\u012bba p\u0113c pthreads PHP izzuda, un tas vairs netika izmantots. P\u0113c tam \u0161ai util\u012btai tika pievienoti v\u0113l da\u017ei funkcion\u0101lie elementi, un t\u0101 joproj\u0101m darbojas. P\u0113c tam tika izstr\u0101d\u0101ts instalators Windows, kur\u0101 bija iek\u013cauts Apache, PHP, MariaDB, pats PHP lietojumprogrammu un r\u012bku komplekts sistem\u0101las mijiedarb\u012bbas nodro\u0161in\u0101\u0161anai, kas tika rakst\u012bts uz Free Pascal. Run\u0101jot par instalatoru, dom\u0101ju, ka \u0161o jaut\u0101jumu \u0101tri atrisin\u0101\u0161u, jo tas ir \u013coti izplat\u012bts un nepiecie\u0161ams gandr\u012bz katram programmat\u016brai. Vai nu mekl\u0113ju nepareizi, vai kas cits. Bet man past\u0101v\u012bgi tr\u0101p\u012bj\u0101s produkti, kas bija vai nu nepietiekami fleksibli, vai d\u0101rgi un ar\u012b nereti nefleksibli. Un tom\u0113r es atradu bezmaksas instalatoru, kur\u0101 var paredz\u0113t jebk\u0101das v\u0113lmes. Tas ir InnoSetup. Rakstu par to \u0161eit, jo man bija j\u0101mekl\u0113, varb\u016bt k\u0101dam ietaup\u012b\u0161u laiku.<\/p>\n

Atteik\u0161an\u0101s no spraud\u0146a par labu savam klientam<\/h3>\n

\nIepriek\u0161 es rakst\u012bju, ka klienta da\u013ca bija p\u0101rl\u016bks ar \u00abspraudni\u00bb. Ir biju\u0161i laiki, kad Chrome tiek atjaunin\u0101ts, un noform\u0113jums nedaudz sagroz\u0101s, vai Windows tiek atjaunin\u0101ts, un custom uri sh\u0113mas paz\u016bd. \u013boti nev\u0113l\u0113jos \u0161\u0101da veida p\u0101rsteigumus publiskaj\u0101 produkta versij\u0101. Turkl\u0101t custom uri s\u0101ka pazust p\u0113c katra Windows atjaunin\u0101juma. Microsoft vienk\u0101r\u0161i izdz\u0113sa visas ne vi\u0146u zarus attiec\u012bgaj\u0101 sada\u013c\u0101. Ar\u012b Google Chrome tagad ne\u013cauj atcer\u0113ties izv\u0113li atv\u0113rt vai ne atv\u0113rt lietotni no custom uri, un katru reizi uz monitoring objekta tiek uzdots \u0161is jaut\u0101jums. Un kopum\u0101, bija nepiecie\u0161ama norm\u0101la mijiedarb\u012bba ar lietot\u0101ja lok\u0101lo sist\u0113mu, ko p\u0101rl\u016bks nesniedz. Vienk\u0101r\u0161\u0101kais variants \u0161\u0101d\u0101 sh\u0113m\u0101 \u0161\u0137iet vienk\u0101r\u0161i izveidot savu p\u0101rl\u016bku, k\u0101 to tagad dara daudzi, izmantojot Electron. Ta\u010du daudzas lietas jau tika uzrakst\u012btas Free Pascal, tostarp ar\u012b servera da\u013c\u0101, t\u0101p\u0113c nol\u0113m\u0101m klientu izveidot taj\u0101 pa\u0161\u0101 valod\u0101, nevis rad\u012bt zoolo\u0123isko d\u0101rzu. T\u0101p\u0113c tika izstr\u0101d\u0101ts klients ar Chromium uz ku\u0123a. P\u0113c tam tas s\u0101ka apaugt ar da\u017e\u0101d\u0101m apvalk\u0101m.<\/p>\n

Daudz koment\u0101ru bija par to, ka m\u0113s kaut kur to esam nozagu\u0161i. M\u016bs tas nedaudz p\u0101rsteidza.

Mums jau ir att\u0101l\u0101 piek\u013cuve serveriem un t\u012bkla iek\u0101rt\u0101m.

Bija ideja par tie\u0161saistes nepiecie\u0161am\u0101 pielikuma izveidi m\u016bsu serveros. Sist\u0113mas administrators nospie\u017e pogu \"lejupiel\u0101d\u0113t sa\u012bsni\", un m\u016bsu m\u0101ko\u0146a sist\u0113m\u0101 tiek nos\u016bt\u012bta komanda uz individu\u0101l\u0101 bin\u0101ra izveidi ar ieb\u016bv\u0113to inform\u0101ciju par piesl\u0113g\u0161anos nepiecie\u0161amajam serverim \/ datoram, izmantojot RDP.

Viens fails, viena poga un nek\u0101di uzst\u0101d\u012bt\u0101ji.

GPL licence paredz, ka programmat\u016brai j\u0101b\u016bt ar atv\u0113rtu avotu, un, ja m\u016bsu produkt\u0101 ir iek\u013cauta MariaDB ar \u0161o licenci, tad ar\u012b m\u016bsu produkts j\u0101izlai\u017e p\u0113c \u0161\u012bs licences.
