Nyob rau kuv thawj cov hauj lwm tawm ntawm kev kawm ntawv nyob rau qib siab 1991, Yog kuv muaj hmoo yuav mus ua hauj lwm rau lub tuam txhab raug nrog 13 qhov chaw, tsis nrog nws cov neeg HQ hauv New Jersey. Kuv nkaus xwb thaum lub tuam txhab ntawd dov tawm ERP zog. Peb muaj ib me me nws ua hauj lwm muaj li kaum tawm huv tibsi, ob tug neeg uas ua tsis taug. Ib feem ntawm qhov kev tsim koom qhov IBM System 36 thawv HP radon thiab HPUX. Txhua leej txhua tus siv hlab ntsuab rau hauv tsev, lawv.

Peb tes num rolls raws thiab kuv kuv xa rau Baltimore cov nqi nyiaj tshiab, Jeff. Peb txoj hauj lwm yog rau cov hwj huam tuaj rau ntawm lub box Unix, xyuas kom tseeb tias cov O/S khiav, nruab ib lub qhov system ERP, configure lub ERP, tsheb nqaj hlau nyob hauv cov ERP thiab ua kev cai ua hauj lwm rau folks rau ntawm qhov chaw. (Qhov no yog ib txoj hauj lwm uas tsis yog npau suav, pheej los ncaj nraim mus kawm ntawv qib siab). Ua ntej peb yuav yeej tau tawm hauv av, peb yuav tsum tau mus unpack tag nrho cov ntsuab hlab, muab cia rau hauv desks thiab wire lawv. Thiab ib sab zoo tshaj yog tias peb yuav tsum tau muab tso rau RJ11 connectors ntawm tus kheej.

Vim tias tsis txhob to taub thiab yeej ib txwm tsis xav mus kom txog thaum lub sij hawm, peb twb muaj ib co contracting lag tuaj thiab khiav cable thoob plaws rau tsob nroj, tab sis peb tsis muaj cia rau cov connectors. Li ntawd, muaj ib tus "thaj kem" nrog dozens txog unlabeled cables nyob rau hauv lub "computer hoob" thiab cov snaked nyob hauv lub tsev mus rau ntau qhov chaw hauv lub tsev.

Peb ua haujlwm peb txoj kev los ntawm nws dua ib lis xaus kawm kom, soj ntsuam txhua hlau, muab rau ib connector (Yog koj paub tseeb tias nws ncaj vs. hla), txav lub ntsis nqis rau hauv cov hlab ntsuab thiab printers los yog, labeling nyob ntawm tej, ua zoo saib kom "getty ntawd" yog khiav kom haum rau txhua qhov chaw nres nkoj thiab tej zaum ib txhiab lwm yam uas kuv twb suppressed txij thaum ntawd los. Txhua yam nws tuaj ua ke heev nicely.

Tab sis npog, yog ib qho tseem ceeb cable uas peb tsis tau paub tseeb. Nroj tsuag hauv Baltimore muaj ib cov kev sib raug zoo nrog rau ib qhov chaw warehousing hauv New Jersey. Ib txhia muab tso rau hauv Baltimore shipped tawm ntawm qhov chaw ntawd. Muaj ob tug nyob ntawm tej uas peb yuav tsum tau xa mus rau ntawm lub box HPUX: lub raj ntsuab thiab ib lub tshuab luam ntawv. Cov raj ntsuab yog yooj yim, tab sis lub tshuab luam ntawv txia ntshis ua ib tug npau suav phem peb lub lis piam.

Yog hais tias koj tsis paub nws, los yog suppressed nws, soj ntsuam txog kev mob hlab ntsuab thiab printers li no, muaj ntau ntau yam kev xaiv uas koj tsis los teev ntau pins. 8-ntsis, 7-ntsis, parity (Txawm/khib/All), tej zaum luag. Yog hais tias koj tau txais ib qhov ntawm cov chaw no tsis ncaj ncees lawm, cov raj lossis luam ntawv tseem pom tias yog khoom, tab sis nws yuav ua tau tag nrho gibberish, nws yuav tau gibberish nrog khoom coj los ntau ib nrab. tau mas, cov pins no tsis pom thiab yuav tsum muab teev cia siv tus me ntsia hlau pav ca-ntug tsav. Thiab nws yeej ib txwm tsis txheem.

Peb teev ib ntawm ntau ceev hu nrog tus txiv leej tub NJ (lub grizzled computer hater uas tej zaum hais Ius dev. peb mus no ib hnub). Peb tau txais ntsuab raj ua hauj lwm zoo nkauj sai sai, tab sis peb tsis tau txais txoj kev luam ntawv mus ua hauj lwm. Nws cia "khib luam ntawv". Peb yuav ua RJ11 connector, switching tso thiab ncaj. Peb yuav rho tawm qhov chaw nres nkoj thiab rov tsim nyob rau hauv Unix. Peb mus txog arduous ua hauj lwm ntau rau nws piav rau peb lub koob configuration ntawm lub tshuab luam ntawv, yeej tsis yeej paub hais tias yog nws tug ua nws thwj.

Nws yog hais txog lub sij hawm mus nyob, txhua yam nyob rau hauv Baltimore no humming, tab sis peb tsis tau txoj kev luam ntawv cursed NJ ua hauj lwm! Peb twb sab lim tag nrho possibilities tsuas yog tsav ze NJ rov qab mus ua hauj lwm rau lub tshuab luam ntawv nyob hauv cov neeg. Yuav tsum tsis txhob tsav tsheb tas li, peb thaum kawg nug nws fax rau peb li cas nws yuav txais thaum nws "khib", hoping uas tej zaum yuav muaj ib co clue nyob ntawd tej khoom uas yuav hais rau peb paub peb nyob nraum ua dab tsi lawm.

Thaum peb tau txais tus fax mus, peb tam sim ntawd paub zoo. Saib, peb txoj kev tshuaj ntsuam seb peb muaj configured ib lub tshuab luam ntawv thwj kom txog "lp ib tug" hais kom ua li no:

lp/yam/passwd

Yeej, peb sau seb cov ntawv lo lus zais unix. Nws yog ib txwm tam sim no thiab ntawm lub thawv, Nco ntsoov cia ib sab. Koj txheem Unix lo lus zais cia zoo li tej yam zoo li no:

Smith:*:100:100:8A-74(chaw):/tsev/smith:/usr/rau hauv/sh qhua:*:200:0::/tsev/qhua:/usr/rau hauv/sh  

Peb yuav tsum tau luam ntawv seb cov ntawv lo lus zais tsiv rau ob peb vasthiv thiab nws tau luam ntawv kom raug. Txawm li cas los, rau cov neeg siv tag, yog "khib luam ntawv".
