I created a script to flush my sendmail to another mailserver. Because it takes some time I want to give some simple feedback using a rotating bar.
Code:
I'm convinced this can be done much nicer with 'awk' and printf, but somehow awk makes me dazzle..
I have recently upgraded my Debian unstable to the new custom 2.6.34 kernel. The system is unresponsive and top shows two processes (flush-8:0 & flush-8:16) taking up most of the cpu time.
View 3 Replies View RelatedI believe I have unwanted ' characters left in a 9 element character array that are causing subsequent operations with it to fail. I see wildly differing views on the web on the proper way to flush 'em. It's clearly not as simple as it would appear at first sight. What's currently the best (or else "least deprecated") method?

Even after restarting mysql and the host. After some googling and trying I found out "flush tables with read lock" gives the same result. The tables seem to be MyIsam. I tried with a mysqldump on one server and restore it on a test vm. I used the same config and flush logs still hangs. ALso I tried to change some configuration directives... but with the same result
Edit: btw, I checked the logfile and didn't found anything (/var/log/mysqld.log)
Edit2: I also did myisamchk -s *.MYI (in all direcoties with db files;actually did it with find command) and it did not return anything so datafiles seem ok.

I want to search an entire subtree of /, in the file system, for all files, with extension html, created on the hard disk. In addition, these have to be the last five created. I think I could split the problem into two parts: (a) Forget about the last condition. Then this is a job for the find command. (b) Sort the output of find using the date as the key, then use 'head' to print the desired output. But even two such simple steps are enough to justify the writing of a shell script. And here lies my weakness.
My script writing knowledge is rudimentary. What's the final purpose? Well, I lately saved four or five LQ pages onto disk containing information I consider valuable to me. But I don't exactly remember where on the disk. Then: either the problem posed is really of a very simple nature or it is not, in the latter case a script being mandatory. One of the algorithm drawbacks (the one described above) is that find may be running a great deal of time. My machine resources (RAM and CPU speed are low) are scarce and there possible are a large number of HTML files on the disk.
I have created a file with a pre-defined size as follows:
Code:
#define FILEPATH "testfile"
#define FILESIZE 16

I have list of programs which I have created during the past few days, all the programs are attached in txt files, and if anyone can do favor, and double check if they work, and what changes I can make to make it look different, or to improve it.

View 13 Replies View RelatedMy program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.

By allowing for the red, green, blue, and alpha values to be fine-tuned, the user can control how transparent or opaque their desktop is. And how is this possible? C++ instead of C. How do you guys think of being able to customize RGBA?
View 14 Replies View RelatedI have an awk program that finds all files of a specific filename and deletes them from selected subdirectories. There is logic in the awk to avoid certain subdirectories, and this is initialized via a parameter in the beginning statement of the awk. The parameter should have all of the subdirectory names at the top level. This varies from time to time, so I cannot hard-code the value.I'm having a problem initializing the awk parameter using sed. I'm setting a variable (named subdir) using an "ls" command piped to "xargs". I'm then trying to substitute that value into the awk using the sed command.

View 8 Replies View RelatedUsing C++, I want to process sub-folders on my home folder sequentially each with a special naming format and containing some binary files in it:
Code:
1/
2/
3/
4/
5/
6/
...
Give above folders, I will process files in 1/ at first, 2/ at second, 3/ at third, and so on.
For some n/ folder, if I realize that n/ actually does not exist in local file system, I do not want to wait for it. Hence I will keep processing (n+1)/ folder, and so on.
However, when processing some (n+m)/ folder, previously not processed n/ folder may have been created on local file system. In this case, I do not want to miss processing it, but somehow detect its creation and process it. After processing n/ folder, I want to continue from (n+m+1)/.
I recently set up a mailserver on ubuntu using postfix. I set up the MX record with my router's ip address and I have port 25 forwarding all the mails to the ubuntu server. Everything works fine but I am unable to access my email using example.com/squirrelmail from any other machine apart from the server.
View 7 Replies View RelatedSlackware64 13.0 I have a website that has been migrated to a new server. After a few days I'm still pointing at the old server and the hosting company have recommended that I flush my dns cache. A quick google for this in linux seemed to recommend restarting the nscd daemon but nscd -g tells me it's not running anyway. I connect to Virginmedia via wired ethernet to a Belkin N1 router so is there a way I can do this I wonder, either via Virginmedia or Slackware?

I have an HP printer for my Lenny which has worked for some year. But I don't remember what method I used to install it. So this is one piece of the puzzle that I can't see. But like I said the printer works. One day I accidentally printed more than I had papers in the printer-machine. Then I kind of stacked a lot of print jobs in the queue out of frustration. So whenever I reboot the PC/Lenny then it waste some paper by printing things that got stuck in the printer queue. It's not very environmental this weird behavior.
So next time this happens how do I flush the Printer queue so Lenny doesn't remember what happened before the reboot? I followed these instructions earlier but it only switched one weird behavior with another weird behavior. So it didn't work for my Lenny, and I couldn't find any better solutions on the Internet.

I have two boxes, 1- Centos router, 2- centos web/mail server..
When trying to receive mail using mail.xxx.xxx in the mail client server settings, it will not resolve to any machine on the internal network... I have to enter the internal IP address in the incoming and outgoing email settings..
Same with the website I host.. I have to enter the internal IP to get access..
It just will not resolve the DNS on the internal network.
Everything works as it should outside my network.
I am trying to set up a mailer server on Lucid Lynx using mostly this guide: [url]
I believe I have most of the basics covered. But before launching into the the advanced set up, I want to see if I can get help with one thing I am finding difficult to understand.
In terms of my domain name www.example.com, do I have to do anything on my hosting company's side? That is, www.example.com currently have my web site and it is hosted on a private server at a hosting company. I have the ip address of the server. When I configured postfix, i used this same domain name in the configurations so I want to know what else to do to get it working.
I am using this command (inside a bash script) to check if mailserver is running correctly (port 25)
# echo | telnet localhost 25 | grep "Connected to "
If it does not respond I receive an email alter.
It works good , but sometime it NEVER respond (neither after 1 hour) , so I receive no notification . DO you know alternative command to the command above ?

I want to run a mail server from within debian linux guest with vmware workstation xp host. The setup is a bridged network connection
Here are things that need to be done:
a)Configure the Guest with a static IP on my home network. Verify that I can telnet to port 25 of the Guest from a system on my home network.
b)Then configure my home firewall/NAT box to forward incoming connections on TCP port 25 to the static IP address I gave my Guest. Then test that I can telnet to port 25 from a system outside my home network.
c)After that I need to configure the appropriate DNS records for my domain so that outside hosts know how to contact my mailserver.
Does a mailserver have to have direct access to WAN or can it be a LAN device with just one NIC ?
We have two WAN access points.
One is an adsl router joined to the switch and all seems fine for internet browsing.
The other is a wireless system with a linksys router joining by way of PPPoE and this appears to connect fine.
This PPPoE is direct to our ISP and where we need to downlod our mail to our pending mailserver.
When the linksys router is also joined to the switch all devices can use either the adsl or linksys to roam the net. 192.168.1.1 linksys & 192.168.1.10 is adsl.
When I join the linksys direct to the mailserver I will then need two NIC's. One for the Linksys and one for the LAN.
This is where the fun has started.
So.... Can I just have one NIC (connected to the switch) on the mailserver?
Still trying to get that elusive simple mail server. Have install Centos 5 (20 time!) and updated software. Have got the system to see www and now about to do the mailserver thing. One of the first steps is to install Clamav yet this does not show on the package list for the program add delete gui. Tried yum install clamav and got message back that it wasn't available.
Google advises that I must first install rpmforge but at the same time has a warning from the maker of yum that this is dangerous to do Clamav is clearly a very popular antivirus scanner yet Centos 5 does not include it or allow you to install it?
