Kollec həyata mənim ilk iş yerində 1991, Mən bir istehsal şirkət üçün işləmək üçün uğurlu olmuşdur 13 locations, 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.

Layihə boyunca rulolar və mən əməkdaşı yeni ilə Baltimore nazil alıram, Jeff. Our job was to power up the Unix box, O / S qaçdığı əmin, ERP sistemi yüklemeye, ERP konfiqurasiya, train people on the ERP and do custom work for folks on the spot. (Bu yuxu iş idi, xüsusilə düz kollec gələn). Before we could really get off the ground, biz bütün yaşıl borular açmaktır üçün lazım, put them on desks and wire them. And the best part was that we had to put the RJ11 connectors on ourselves.

Mən vaxt başa heç və faktiki haqqında soruşmaq fikir heç vaxt ki, bəzi səbəbdən, biz bir podratçı şirkət zavodun boyunca birlikdə gəlib və kabel run idilər, but we didn’t have them put on the connectors. Belə, there was a "patch box" with dozens of of unlabeled cables in the "computer room" və bu bina müxtəlif yerlərinə Binanın ətrafında snaked.

Biz bir həftə ərzində vasitəsilə yol işləyib, hər tel test, bir bağlayıcı qoyulması (arxayın o düz vs idi. qatışıq), yaşıl borular və printerlər bit parametrləri düzgün təmin, 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.

Lakin, 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, lakin Çap üç həftə qarabasma çevrildi.

Siz onu bilmirəm, və ya onu yatırıldı var, yaşıl borular və printerlər bu şəkildə məşğul, there are various options that you deal with by setting various pins. 8-parça, 7-parça, bərabərlik (hətta Tek / / none), probably others. If you get one of those settings wrong, boru və ya printer hələ heyəti göstərir, lakin bu ümumi gibberish olacaq, or it will be gibberish with a lot of recognizable stuff in between. Əlbəttə, these pins are hard to see and have to be set by using a small flat-edge screw driver. And they are never standard.

Biz NJ oğlan çox tez zənglər ilk qurmaq (bu gün kim yəqin ki, küfrlər bizə grizzled kompüter qənim). 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, həqiqətən əmin heç vaxt o düzgün bunu əgər.

Bu canlı getmək barədə zamanı, Baltimore hər şey uğultu olunur, lakin biz iş NJ ildə lə'nət Çap qədər ala bilmir! 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", bəlkə biz səhv yapýyorsun nə deyəcəklər ki, zibil bir ipucu olacaq ki, ümid.

Biz faks var zaman, we immediately knew what was wrong. Görmək, our method of testing whether we had configured a printer correctly was to issue an "lp" bu kimi komanda:

LP / etc / passwd

Əsasən, 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:

dəmirçi:*:100:100:8A-74(idarə):/Ana səhifə / smith:/usr / bin / sh
:*:200:0::/Ana səhifə / qonaq:/usr/bin/sh  

We had been printing out the password file over and over again for several weeks and it was printing correctly. Lakin, son istifadəçi üçün, it was "printing garbage".
