Prize of being an Admin - Part 2
I was reading this thread of admin_xor Prize of being an Admin and thought will share this experience of mine which is kind of opposite to what he did - I didn't tell anybody what happened 
We were porting one of the subsystem from Solaris to Linux. As part of that we developed many wrapper scripts. So, there is this rsh wrapper script which is deployed in the system which internally uses ssh if security is enabled or uses native rsh instead (this native rsh is placed in a different path, so that it will not show up in the $PATH and the wrapper rsh script is placed in /usr/bin). For some testing purpose, I modified the ssh command inside the rsh wrapper script to "rsh" command and forgot to change it back. So, you know what happened next. If I do a rsh, it goes into a continuous loop calling the rsh wrapper script over and over again, this clogged the cpu in no time. I did this change in the Testing teams setup. And the worst part was I did it in 2 of their setup.
Next day I came to office and there is a big fuss all over the place. I didn't bother cause it was't assigned to me and I totally forgot that what I did was causing this. After couple of days, the issue was assigned to me and then "oops" I realized it. Now what? Of course I didn't tell them. Hearing about what happened to admin_xor for what he did, imagine what would've happened to me.
Later I told them that it was a "human"
error and that there is no issue with the system. But then they asked how could it happen to 2 systems. I was like "it happened man, forget it" - no I didn't say that, I told them we'll monitor it. I assured them that it is human error and we will monitor the system and if it re-occurs we will investigate again and now its not worth spending time on this - obviously I know it - cause I am the culprit.
