Ubuntu Installation :: Warning - Can't Create Test File /var/lib/mysql/mosty.lower-test
Mar 15, 2010
I am trying to install mysql 5.1.44..so i downloaded the binary package, i extracted it and then followed the instructions that were in the manual but i keep getting this error when running this command
I was playing with the mysql my.cnf file yesterday, trying to move my database files to my dropbox folder so I can use the database on my other machine. All I changed was the datadir setting to point to my dropbox folder. I also moved my mysql data files there.
When I tried to restart mysql and test the new location it said my mysqld.sock was missing. I searched and searched the web and my filing system for it but I have no idea what's happened to it?? I have even tried changing the datadir path back and reinstalling mysql but that doesn't seem to work either.
I have created mobility of 20 nodes and vbr traffic using following attached script I executed the file as ns234 vbr.tcl I got the vbr.tr and vbr.nam but I was unable to load the graph using matlab <trgraph> I thought problem with is vbr.tcl script.
I know very little about MySQL, but I've got some users that need it for testing on a Linux server.So I had set it up a while back, but now I'm running into some small problems.Right now, each user has his own database that I created and can do whatever with it. Each user only sees their own database.I didn't want them to be able to create new databases at all, but they can and when they do anyone can see them.
EDIT(Apparently they can only create databases beginning with the word "test" in the name)
I need to either:
1) Stop them from creating new databases (without affecting their ability to interact with the existing database)
2) Make it so that when they create a database, only they have privileges on it and only they can see it (except mysql root of course).
Anybody know the statement to set these kinds privileges up?
EDIT: pfft... I've a read a bit more and realize that this is an intended part of the installation.
I'd still like to remove the ability to make test databases.
EDIT3:Ok, for reference this is how you prevent users from making and using test databases:
shell> mysql -u root -p Enter password: (enter root password here) mysql> DELETE FROM mysql.db WHERE Db LIKE 'test%'; mysql> FLUSH PRIVILEGES;
I already install mailgraph in ubuntu 10.04. but now I got problem with mailgraph in ubuntu 10.04. No graph appear in the graphic created by mailgraph.I know mailgraph consist of perl and cgi script.If I have postfix log, how to test mailgraph manually to create the graphic using its perl script from existing postfix log. Just to see whether the graph created or not in the graphic
I want to copy files from an incoming directory, but don't want to copy a file if it hasn't finished being written. I thought of using fuser, but it doesn't seem to be very reliable. I vi'd a file in one window and then ran fuser against the file name and got nothing back. I'm just writing a simple bourne script on RHEL.
I would like to be able to test that a network mounted cifs(samba) share is actually mounted in a script file to do backups. I want to do this so that when my automatic backups run they actually go to the remote location or fail. Currently, if there is a network problem that prevents the network share from mounting, the files simply get copied to the folder (e.g. /media/backupmount) and end up filling up my small local hard drive.
I'm working on testing some software, and I have a question. We have several files of binary data that we need to push through our application to test. It communicates via simple TCP sockets. Is there a way I can send this data to the socket from the command line? I tried doing something like this, but telnet never picked up the data.
using tomcat6 server os is fedora9 i need to run test.jsp file every 20 minits i assigned the cron job */20 * * * * wget http://<my host>/containfolder/recurring.jsp but, its take long time so i need to run test.jsp file in linux command prompt, Is it possible to run JSP in linux command prompt?. If there is yes mean, plz tell how we can do that.
I think I had this problem before but I don't remember what was done to correct it. I just tried to do an update and got this error message.

Trying to use tcpdump -r TEST, and get permission denied, even though I am logged in as root or super user. Tried using the "chmod a+rw TEST" (any other file for that matters, yes it came from another source) and get permission denied.
If you still have windows on some of your machines and a bit of free drive space, your help testing Wubi for the 10.04 Lucid release would be most welcome.Please use the latest Wubi version available on [URL] There is no need to burn or use a CD, Wubi will automatically download and use the latest daily ISO.If you have any issue, follow this procedure:
Uninstall and try with a clean installation using the latest revision from the above link If that does not help, when you reboot into Ubuntu the first time, you can press ESC for more installation boot options, sometimes those fix the issue. Check [URL] if there is already an open bug, in case feel free to add a comment in there If none of the above helps, feel free to ask on this thread (I am subscribed). If you think you stumbled upon a new bug, an even better place for reporting your issue is [URL] More points if you attach the wubi.log file which is located in your user temp directory.
Here the description of the issue I am having.I am writing a bash test script which reads lines from a file, builds ISO messages, sends them to a server, reads the response with response code and reports the result of the test to a file or on the screen.The message that I need to send is 94 characters long.Here's the portion of a code that I initially wrote:
#~ Open socket. exec 3<>/dev/tcp/172.26.0.25/9991 #~ Send msg.
i have the mandatory 50 posts about how 'windoze' is terrible and ubuntu is much better blah blah etc. I need to test some software on a windows XP machine. I have an Ubuntu laptop. When I try to run my XP disc it tries to get going, but inevitably gets to a blue screen of death (ahh, I missed windows).
Ideally I want a dual boot machine- A massive XP partition with a cute little Ubuntu partition on the side. Failing that, I need XP installed on this laptop. Possibly relevant specs are as follows:
I am new to linux having just abandoned Windows due to stability issues. I have a Hauppage remote with a usb ir receiver. This worked fine under windows using the drivers for the windows media center remote. I can't however get this to work under Linux. What I am really looking for is a method, perhaps using a command line in the terminal window to be able to test and see if the OS has actually detected the device. I have tried irw, but there is no response. If I know that the device is connected, then I can start looking at issues of identifying the correct drivers for the device.
I'd like to upgrade to 10.04 from Karmic but want to make sure it will leave me with a working system afterwards. I figured a good way to test it is to create a disk image with dd and then try upgrading in VirtualBox using that image. The idea is that if it is successful, it'll probably be successful on the real machine too.
The only problem is my home partition, which is >1.4 TB. I don't have that much space left on any other hard disks. So I would like to somehow exclude certain directories in /home (or the entire partition) from appearing in the image.
Is this even possible? Or does anyone have any better ideas?
I am trying to istall litb for P2020DS. I got an error the following error:
[hwtesting@HWLSRV1 ~]$ cd /home/hwtesting/ltib-p2020ds-20091119 [hwtesting@HWLSRV1 ltib-p2020ds-20091119]$ ./ltib Don't have HTTP::Request:ommon Don't have LWP::UserAgent Cannot test proxies, or remote file availability without both HTTP::Request:ommon and LWP::UserAgent
add folowwing line to User Privilage section:
hwtesting ALL = NOPASSWD: /bin/rpm, /opt/freescale/ltib/usr/bin/rpmvisudo
I edit the sudoers by visudo command and insert this line just under the following line:
root ALL = (ALL) All
But still I am getting the following:
Don't have HTTP::Request:ommon Don't have LWP::UserAgent Cannot test proxies, or remote file availability without both HTTP::Request:ommon and LWP::UserAgent
The disk I obtained from a seller runs fine in live mode (no installation) on my Windows XP. I liked what I saw. However, when trying to run cd live on my Linux PC it won't run. Linux pc currently has Kubundu 9.1 installed. Previous to that I had Mint 8 installed, but again Fedora 12 cd would not run. After getting an initial Fedora startup screen, I next receive a bunch of text, ending with a text screen of about 30 lines with "OK" in green to right of each line. At bottom is blinking cursor. That ends my machine's live running of cd.
Obviously, if I can not get cd to run live on linux pc, I'm not going to be able to install. (I should add that ubuntu, kubuntu, mint 8 and pclinuxos all ran successfully live on machine and three of them were installed successfully.) Perhaps, Fedora is at war with Ubuntu et al.
