Is it possible to list all jobs and their pids from a certain time frame? For instance if I needed to see all completed jobs from yesterday how would I do this? I've tried jobs -n but that was messed up because I had typed jobs right before that.
View 1 RepliesI run a small home server (Debian 4), which acts as my gateway to the internet (ie, firewall) and runs a web server, dhcp, dns, and acts as a file server to the rest of the machines on my home network. Now I know it's never a smart idea to have all those services running on the same machine that is acting as a firewall, but I don't fancy running multiple servers just for home use, as it's mainly allowing me to learn system administration.
I noticed a few days ago that my internet had become unbearably slow, to the point where I could sometimes not load web pages. I spent a while searching through log files on my gateway, to try and find out what was eating up all of my bandwidth. When I came to apache's access.log file, I was confronted with this:

Multiple requests to my server, for totally random websites. I didn't even know it was possible to make those types of queries to a webserver. The only thing that is on the web server is a browser based torrent client. I have only shown a small snippet of the log file, but there are around 90k lines to different web addresses, from many different IPs. What I want to know, is what is happening? :S Why is someone querying MY web server, for web sites totally unrelated to it? And most of all, how can I stop it. My initial was to try and use iptables to block multiple requests from the same ip within a certain time frame, which I think would work as the server shouldn't really get many queries from external networks.

View 2 Replies View RelatedI was reading some code the other day and thought that I saw they were using the list.pop method to pop of more than one item at a time. Something like this.
Code:
l = [ 'a', 'b', 'c', 'd', 'e' ]
l.pop(0:3)
['a','b','c']
l
['d','e']
But of course when I looked at invoking the method, it only works for one item at a time. I'm working on a data structure where I'm parcing weather data that is 15 items long that are return in as data in a list that has 3,000 + items. I was wanting to pop off a lists of the 1st 15 items breaking them into chuncks (still trying to figure out how I'm going to store the associations as each day has 2-4 readings an hour for the past 72 hours, so I was wanting to group the days together but have each data point for each time).
I know I can just write a function (with some additional tweaking needed for neg starts to work on the right end):
Code:
def longpop (seq, length=1, start=0):
slice = seq[start:start+length]
del seq[start:start+length]
return slice
But with increasing data sizes, I was wondering if there was a faster built-in way of doing this (perhaps implemented under the hood written originally in C as an extention, for example).

I checked the error.log file : Code: TagLib: ID3v2.4 no longer supports the frame type TDAT. It will be discarded from the tag. I'm guessing it has something to do with that.

View 4 Replies View RelatedHow to submit multiple jobs onto a Linux server. The only way I know to submit and run a job on a server is using qsub, and verifying the status of the job using qstat. I usually run my scripts using qsub -cwd so that I can run it on my own directory (instead of having the results sent to a scratch folder).
1. However, assuming qsub/msub are not available, is there another way to do it? What commands can I use instead?
2. I know that some jobs can run in the background, is that an alternative? How do I do it? And would I still be able to check the status of the job or delete it?
