Below is data taken from my dedicated server:
[Code]...
I need a script that I can run on an hourly basis that will:
1. Calculate the total downtime since the first date
2. The overall downtime percentage
3. Store this data in a file at /home/bla/file.txt, in the following format: TotalDowntime=03:02:02 Average=0.01%
I write a bash script to time some downloads from a server using ftp connection. ( something like: "time ftp 'options' ) I need to count the time for a list of files in a loop and output the result in a file.

View 1 Replies View RelatedI need some help recovering from a "slight" screwup. We just moved 3 TB of data from one RAID Array to another. Low lever archive files. This was done with a regular cp (for some reason) and now we have lost all the timestamps on the files, and we urgently need to get the timestamps back on these files.
We are running Ubuntu 9.10 Server and we have mounted the following
1. /mnt/old-raid ##Old raid from the old server
2. /mnt/new-raid ##New raid on the server
I know we can read out the timestamp on the old server using the command stat -c '%Y' <<filname>>
I know we can change the timestamp of the file, using the command touch -d '<<date>>'
To get from the stat -c date to the input date in touch we need to use date -d @<<timestamp>> +'%d %b %Y %R'
So my question is, how can I create a loop that will list all files in a folder, get their timestamp and update the old timestamp with the new?
I have this script in the past for csh: Code: ./a.out |& tee prints.txt which will redirect all printfs in the C program to the prints.txt file and at the same time show them in the console. How do you do this in bash? I have seen this, [URL] but it does not work for my bash and sh shells. It says:
Code: -bash: syntax error near unexpected token `&' and
Code: -sh: syntax error: unexpected "&"
I would like to implement something when a server is offline for whatever reason. For example. I got my own DNS servers and webservers. I would like it if the users goes to www.somedomain.com and the server it is actually on is down for maint. or For whatever not able to respond. What can be done so that if the server isn't able to be contacted that it can point to either a another server or the dns somehow can display a page stating who to contact to report a problem or to let them know its down for maint. And can goto a site to check the status or whatever.

View 1 Replies View RelatedI'm trying to get a bash script to do different things based on the time of day, but at least once a day the test fails:
Code: Select allNOW=$(date +%k%M)
if [[ "$NOW" -ge 1000 ]] && [[ "$NOW" -le 2200 ]];then
alarm lon
else
alarm loff
fi
This is the error, and line 59 is the second quoted above:
Code: Select all/home/electrolux/bin/ts.sh: line 59: [[: 059: value too great for base (error token is "059")
The script is run every minute, and this error only occurs at 12:59AM, or 00:59.
I presume the problem is either $NOW is being set to 059, or the testing is seeing 0059 as 059. I think the latter, because for the rest of midnight 'til 00:58 the script works. And with some Googling it seems that the leading 0 is making test treat the number as octal... is there a way to tell it it is decimal?
Perhaps this is just some poor time-testing code? Looking at it I don't think it will cope with set time period that crosses midnight..... there's probably just a command to do what I want, isn't there? I know I could have two different scripts cron'd for the different time periods, but it would be much more preferable to be just the one.
I am trying to find a nightly backup if it was successfully copied over, rename it and curl, but it's always passing the check even if the file is older than specified. From the command line it does as it should. Example is here;

- nothing returned (good). Then I change the time

I have a set of machines on a disconnected network. Periodically, one of the machines connects to the internet and synchronizes its time with a time server that is not known until the connection is established. (The machine queries a central command server for the address of the time server it should synchronize to.)
I then use a custom tool to do some calculations to call adjtimex() and adjust the clock so that it runs fairly accurately.
I know ntpd is supposed to be able to handle disconnected networks but I thought you had to preconfigure the servers in the configuration file.
My intent is to run ntpd on this machine (without configured "server"s) so that it can serve time to the internal network. (Periodic synchronization using ntpdate from the internal machine to the bridge machine.)
The problem: ntpd wants to fuss with the values I set using adjtimex(). I want it to quit thinking it needs to adjust the clock and just serve time to the internal network. (Maybe I have a GPS time source hooked directly to the machine!)
I want to synchronize my time to a time server in Singapore. How can i do so with the Time and Date in System - Administration - Time and Date?

View 4 Replies View RelatedI have a bash script that is tracking ERROR connections (running in a cron every 15 minutes), sometimes the errors are true and are not connecting. But most of the time, the disconnects/reconnects are between 30 seconds are sending out false positives.

Everytime I log into the linux server at my workplace (I use putty), I don't get the bash prompt right away. I need to execute the command 'bash' to get it. Anyway to make this automatic? e.g.
Code:

I am trying to synchronize the time of my VM server with ntpd. I have the following configuration. And in the /etc/ntp.conf, I have the following line:
restrict default ignore
restrict 127.0.0.1.
server time1.server
server time2.server
Whenever I have this line, the erver is not able to synchronize its time... So far as I understood, this line prevents other servers using this machine as a time server. And the second line says to allow localhost to use as time server. But why do I need to use its own time server when I have specified to use time1.server and time2.server ? ( firewall for tcp and udp ports 123 is open)
However, when I replace the first line of the configuration with the following line, it works. restrict default kod nomodify notrap noquery But with this, i am allowing other servers to use this server a ntp (which I wouldn't like to). Why this machine tries to use ntp server of its own (to snyc time) and why it is not working though i have the entry "restrict 127.0.0.1" ??
I want to know the time on a server accurate to the millisecond.there's this way:

I have scowered the internet for the answer to this one. I need a script to rename multiple files to the same exact name, run a program on the file then do the same for the next file. We have a unix backend system that is expecting to load the file with the filename of cards.in So I will have files named card.2009xxx, like i said i will have around 4 or five of those. I want the script to rename card.2009xxx to cards.in, run our unix program on cards.in which inturn changes the file name and once complete i want the script to rename the next cards.2009 to "cards.in"Until there are no more left in the directory and the unix program has processed all the files. All of this is occurring in the same directory. I have written some scripts but they fail by moving for example cards.200901 to cards.in then immediately moving cards.200902 to cards.in and that is not good because it is overwriting valuable data

Now only can do this manually; when gdm starts, switch to any text tty [ie.

With this steps:
Code:
$X :1 -verbose -nr -nolisten tcp &

$export DISPLAY=:1
$JavaApp &
Now i need put this steps (script) in some place to launch the app automatically, and with and specific user [ie. manager].
How can I made it? Maybe in init.d? or an special xinitrc? And how can start the app with the specific user? And, if is possible, who can stop the app when the system going turn off? I have Debian 5.0 and a beginner knowledge of shell script.

I am wanting to create the smallest server I can possible. I have a small server I use as a print server and for file sharing. The hard drive is about 80GB. Since I only run cups and samba, I see no reason to take up an addition few GBs with major distros just to run the OS. I know it is possible to get a small distro around 50MB or so. I would even be happy with an OS running around 200MB. what would be the best way to go about doing this? LFS is just too complicated and time consuming for the end result. Would something like Gentoo be better? Anything else that I may not know about?
