Igandea Funny: “Garbage da inprimatzea”

Nire unibertsitateko out lehenengo lana at 1991, Zortea behar fabrikazio-enpresa batean lan egin izan dut 13 kokapenak, not including its corporate HQ in New Jersey. I joined just when the company was rolling out a new ERP system. We were a small IT department of about ten people altogether, two of whom Did Not Travel. Part of the project involved replacing IBM System 36 boxes with HP hardware and HPUX. Everyone used green tubes to access the system.

Proiektuan zehar pasatzean, eta nago bidalitako behera Baltimore berri bat co-langilea batera, Jeff. Our job was to power up the Unix box, ziurtatu O / S exekutatzen, instalatu ERP sistema, konfiguratzeko ERP du, train people on the ERP and do custom work for folks on the spot. (Hau ametsetako lana izan zen, batez ere, zuzen izarrekin unibertsitateko datozen). Before we could really get off the ground, berde hodi guztiak despaketatzeko behar dugu, put them on desks and wire them. And the best part was that we had to put the RJ11 connectors on ourselves.

Arrazoi inoiz ez dut ulertzen, eta inoiz pentsatu buruz galdetu momentuan egiteko, izan genuen kontratazio enpresa batzuk ere etortzen dira eta kable exekutatu landare osoan zehar, but we didn’t have them put on the connectors. Beraz,, there was a "patch box" with dozens of of unlabeled cables in the "computer room" eta horiek eraikinaren inguruan snaked eraikinaren hainbat tokitan.

Gure bidea egin dugu, horren bidez, asteburuan zehar, alanbre bakoitzean probatzen, Konektore bat jarri (Ziurtatu zuzen vs egiten zen. zeharkatu), hodi berdea eta inprimagailuak ezarpen bit ziren egokiak bermatuz, labeling wires, making sure that "getty" was running correctly for each port and probably a thousand other things that I’ve suppressed since then. It all came together quite nicely.

Baina, there was one important cable that we couldn’t figure out. The plant in Baltimore had a relationship with a warehousing location in New Jersey. Some orders placed in Baltimore shipped out of that location. There were two wires that we had to connect to the HPUX box: a green tube and a printer. The green tube was easy, baina inprimagailua hiru aste amesgaizto bihurtu.

Ez baduzu ezagutzen, edo kendu da, hodi berdea eta inprimagailu era honetan aurre, there are various options that you deal with by setting various pins. 8-bit, 7-bit, parekotasuna (are / bakoitiak / bat ere ez), probably others. If you get one of those settings wrong, hodi edo inprimagailu oraindik ere erakusten du gauzak, Guztira, baina huskeriak izango da, or it will be gibberish with a lot of recognizable stuff in between. Jakina, these pins are hard to see and have to be set by using a small flat-edge screw driver. And they are never standard.

Sortu dugu azkar asko deien lehen NJ zentzuduna batera (grizzled ordenagailu bat hater duten ziurrenik Curses digu egun honetan). We got the green tube working pretty quickly, but we couldn’t get the printer to work. It kept "printing garbage". We would create a new RJ11 connector, switching between crossed and straight. We would delete the port and re-created in Unix. We went through the arduous task of having him explain to us the pin configuration on the printer, inoiz benetan ziur zen bada behar bezala egiten.

Ordua da zuzeneko joan, Baltimoreko dena Humming, baina ezin dugu madarikatua inprimagailua NJ lan! We’ve exhausted all possibilities except for driving back up to NJ to work on the printer in person. To avoid all that driving, we finally ask him to fax us what he’s getting when it’s "garbage", agian, ez batzuek zabor horretan ideiarik gaituen esango zer gaizki ari gara izango zelairatuko.

Noiz fax lortu dugu, we immediately knew what was wrong. Ikusi, our method of testing whether we had configured a printer correctly was to issue an "lp" honelako komandoa:

lp / etc / passwd

Funtsean,, we printed out the unix password file. It’s always present and out of the box, always just one page. You standard Unix password file looks something like this:

Smith:*:100:100:8A-74(bulego):/home / Smith:/usr / bin / sh
:*:200:0::/home / gonbidatu:/usr/bin/sh  

We had been printing out the password file over and over again for several weeks and it was printing correctly. Hala eta guztiz ere, azken bezeroari, it was "printing garbage".
