• What is wrong with my expect script?

  - by Bryan

  I'm trying to learn how to use the expect command, to help me automate deployment of some software via shell scripts, and figured I start with something simple to get me started. I've created a file in my home dir called 'foo' using: touch foo And I've created the following script saved as test.exp #!/usr/bin/expect spawn rm -i foo expect "rm: remove regular empty file `foo'?" send "y\r" When I run the script using ./test.exp, it spawns the rm command, but it doesn't appear to send the Y and carriage return. I know I don't have a typo in the expect string, as I've used copy and paste to put in the script. What am I doing wrong?

• Can I pass the LHS of a cfengine3 processes: line to the RHS?

  - by joeforker

  I'm using cfengine to start the foobar process. Apparently the LHS is discarded when I use process_select? Can I simply pass the LHS to a function, rather than having to put the command match pattern in a body argument? bundle agent foobar { processes: "foobar" # documented way would be to use .* here process_select => command("foobar"), restart_class => start_foobar; commands: start_foobar:: "/usr/bin/foobar"; } body process_select command(c) { command => "$(c)"; process_result => "command"; }

• How to get the basic mail command in ubuntu 10 to work

  - by Maureen Adamson

  I am a college lecturer to whom the task of supporting the students' Linux Server has fallen. My students just need to use the mail command to communicate with me and each other. I thought mail would be there by default but it wasn't. I have tried all the advice I found on the Internet and tried to install mailutils, sendmail, mailx, exim4 and postfix. There were more but I can't remember them all now. After installing (if it works - some of them don't), when I try to send a message they all give me: /usr/sbin/sendmail: file or directory not found. I don't need anything fancy - we don't need to access remote email, just locally on our server. Incidentally the same problems are occurring on the physical server and my test virtual machine, installed at different times but both Ubuntu 10. Can anyone help me?

• mailsend not sending to (or qmail not receiving from) the same machine

  - by roman

  A web applications sends two emails: to the user of the webapp to the administrator the administrators mailbox (qmail) is on the same machine as the web application (php, apache, /usr/sbin/sendmail). email 1 works, email 2 sometimes doesn't work. I don't see any pattern in the mails that don't work. Also because I don't exactly know WHICH emails failed (since the email itself would be the only notification). email 2 looks like this: from: <[email protected]> #changes for each user to: <[email protected]> What could be the problem? Are rejected emails stored somewhere? (if they are rejected.. how do I check this?)

• How do I install something from source and make it available to root?

  - by pwny

  I have a CentOS VM and I need to install the latest version of Ruby on it. Unfortunately, yum only makes Ruby 1.8.6 available so I'm trying to install Ruby from source. Here's what I'm using: cd /usr/src sudo -s wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gz tar -xvzf ruby-1.9.3-p125.tar.gz cd ruby-1.9.3-p125 ./configure make && make install The problem is that once that's done, I can only use Ruby as a regular user but I need to use it as root to install some gems. For example, as a regular user I can do ruby -v and it works but sudo ruby -v outputs bash: ruby: command not found. What am I missing to make stuff I install from source available to all users?

• Automatically mount a remote folder on boot

  - by Andrew

  I'm trying to mount a Windows folder on my Ubuntu machine on start up. I've tried following this page here, modifying /etc/fstab and appending sshfs#my_user@remote_host:/path/to/directory <local_mount_point> fuse user 0 0 to it, but it fails; on start up, I get an error saying that the mounting failed, and I can press S to skip or M to recover manually. I also tried following this page here, appending /usr/bin/sshfs -o idmap=user my_user@remote_host:/path/to/directory <local_mount_point> to the /etc/rc.local file, but this doesn't help either; Ubuntu just boots up normally without mounting. I have Cygwin installed on my Windows machine, and I can run everything smoothly, such as sshing without passwords, and mounting it manually. I've also tried to run the modified rc.local file $ /etc/rc.local, and it works perfectly, but I just can't seem to get the folder mounted on start up. Can someone help me?

• Linux - How to run Firefox with AT command

  - by conualfy

  I try to run a specified command on a desired time. I found at for this, and it seems to work fine if I run: echo "ls -al / > /home/florin/test.txt" | at 4:21am But I want to run a different thing: /usr/bin/firefox -new-tab http://google.ro I tried adapting the first line with my action (running it in terminal opens a new Firefox tab with http://google.ro, so the command is correct), but with at, it does not work: echo "firefox -new-tab http://google.ro" | at 4:23am The task seems to be scheduled, but it does not run. When running the previous line I get the default reply from at: warning: commands will be executed using /bin/sh Should my Firefox command be differently run in sh? Is there a way to do my action with at, or some other way? Thanks a lot!

• Issues with MongoDB install on Ubuntu 8.04 LTS

  - by Tom

  I am installing MongoDB (1.4.1) on Ubuntu (8.04 LTS) and I continuously have a problem where I can be in /usr/local/mongodb/bin and run ./mongo or ./mongod and I am returned "No such file or directory." Let me be very clear here... the files ARE there! The obvious go-to solution is that it is because of permission issues but the permissions are fine. I've even tried others out, still without any luck. I'm really at the end here and any help would be MUCH appreciated. Thank you!

• MySQL Server Not Starting on Boot

  - by Brian

  I have installed MySQL on a RHEL 5 server and I'm wanting to set it up so that the server starts on boot. I've ran the "chkconfig --list mysqld" command and it's currently running on levels 3, 4 and 5. However, when I reboot the server, no mysqld process is started. I've also tried manually starting the server by executing "/usr/bin/mysqld_safe" and I get the following output: Starting mysqld daemon with databases from /var/lib/mysql STOPPING server from pid file /var/run/mysqld/mysqld.pid 100319 10:31:30 mysqld ended I looked in /var/log/mysqld.log and I found the following: 100319 10:29:01 mysqld started 100319 10:29:02 InnoDB: Started; log sequence number 0 29752204 100319 10:29:02 [ERROR] Can't start server : Bind on unix socket: Permission denied 100319 10:29:02 [ERROR] Do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ? 100319 10:29:02 [ERROR] Aborting

• System time wrong after running ntpdate because DST ignored

  - by Ian Dunn

  When I run ntpdate, my system clock displays the time as an hour behind what it should be. I know that ntpdate does everything in UTC, so I'm guessing there's a timezone setting wrong and it's ignoring Daylight Savings Time, but I can't figure it out. Here's what I've done so far: ln -sf /usr/share/zoneinfo/EST /etc/localtime to set the timezone Set UTC=true in /etc/sysconfig/clock so that DST will be automatically applied date -s hh:mm::ss to set system clock correctly hwclock -systohc --utc to set the hardware clock correctly At this point date and hwclock both display the correct time. But if I then run ntpdate 0.us.pool.ntp.org, the date output is an hour behind what it should be. I've looked at a dozen tutorials and can't figure out what I'm doing wrong. Does anyone have any ideas?

• exported variable not persisted after script execution

  - by Daniele

  I'm facing a wierd issue. I've a vm with solaris 11, and trying to write some bash scripts. if, on the shell, I type : export TEST=aaa and subsequently run: set I correctly see a new environment variable named TEST whose value is aaa. If, however I do basically the same thing in a script. when the script terminates, I do not see the variable set. To make a concrete example, if in a file test.sh I have: #!/usr/bin/bash echo 1: $TEST #variable not defined yet, expect to print only 1: echo 2: $USER TEST=sss echo 3: $TEST export TEST echo 4: $TEST it prints: 1: 2: daniele 3: sss 4: sss and after its execution, TEST is not set in the shell. Am I missing something? I tried both to do export TEST=sss and the separate variable set/export with no difference.

• recommended way to collect email notifications from crond in Arch Linux

  - by nponeccop

  Arch Linux doesn't have sendmail installed by default. So I get the following messages in my syslog: Sep 15 13:16:01 zorro crond[18497]: mailing cron output for user collectors sh cronjob.sh Sep 15 13:16:01 zorro crond[18497]: unable to exec /usr/sbin/sendmail: cron output for user collectors sh cronjob.sh to /dev/null What is the recommended way to fix this default behaviour so actual messages are sent? heirloom-mailx is installed and capable of sending email messages using SMTP. Is it possible for crond to use mailx to send notifications? Is there any drop-in replacement for sendmail that sends using mailx? Sendmail is not even in the repositories.

• chdir warning when opening .tar file on OS X

  - by denonth

  I need to unarchive a file to the /Developer folder. Install Qt for iOS SDK The Qt for iOS SDK has been configured to be installed in the default Xcode installation location /Developer. It is not possible to install the SDK into another location without first rebuilding it, as the install location is contained within the qmake executable, and that is built as part of Qt. To install the Qt for iOS SDK, open ‘Terminal’ and type the following from the command­-line: tar –xf qt­-everywhere-­ios­-4.8.0­-xxx.tar.gz –C /Developer (where xxx is an identifier which can be used to determine the build of the iOS SDK eg. arm7-­-nossl) This will install the Qt for iOS SDK into the following path: /Developer/Platforms/iPhoneOS.platform/Developer/usr/share/qt­-everywhere­-ios­-4.8.0 When I perform the operation I get the information: Lions-Mac:Documents User$ tar -xf qt-everywhere-ios-4.8.0-arm7-nossl.tar.gz -C /Developer tar: could not chdir to '/Developer' Any idea what is wrong?

• Alt-tab icon list in Gnome and metacity?

  - by Vinh Nguyen

  Can anyone provide a reference or explain how the icons to the alt-tab list is populated? I would like to specify some icons for some programs that do not have icons, e.g. xterm. I'm using Ubuntu 11.04 with Gnome 2 (Ubuntu Classic) and metacity as the window manager. I did see this thread that mentions /usr/share/pixmap/, but if I use cp gnome-terminal.xpm xterm.xpm the icon was not populated in the alt-tab icon list (even after a logout/login). I do see that the icon is populated when I added the xterm command to the Program Menu.

• OpenLdap 2.4 on centos 6 doesn't listen on port 636

  - by Oliver Henriot

  I have an openldap 2.4 server on centos 6 whose confg I copied from those I have running under openldap 2.3 servers on centos 5 machines. On openldap 2.3, specifying TLSCACertificateFile, TLSCertificateFile and TLSCertificateKeyFile with correct values makes the server listen on port 636. This is not the case on the openldap 2.4 setup. I have configured it with loglevel -1 but I have not seen any clue as to what might be wrong and reading the openldap 2.4 manual doesn't indicate if any of the other TLS related parameters are now mandatory. I don't think so though because if I run the service manually, using "# /usr/sbin/slapd -u ldap -h "ldap:/// ldaps:/// ldapi:///"", the server does listen on port 636 and I can query it using "ldapsearch -H ldaps://myserver:636". Is there something I am missing to get the server to listen on port 636 without having to always launch it manually? Is this linked to centos 6 or openldap 2.4? Thank you. Cheers,

• /data/tmp on database server?

  - by Mellon

  I am on a Linux ubuntu machine with MySQL installed. My teacher gave out an assignment which mentioned "copy cars.dat to /data/tmp on the MySQL database server" without any explanations, I do not know what is the "/data/tmp on database server" means exactly? Basically after that I need to execute SQL statement like LOAD DATA INFILE '/data/tmp/cars.dat' INTO TABLE cars So, what does copy cars.dat to /data/tmp on the database server means as there is no /data/tmp directory even? Personally, I checked /etc/mysql/my.cnf file, inside which there are definitions of : ... basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp ... Does it mean to copy cars.dat to the tmpdir which is just /tmp under root directory??

• Linux script to find time difference and send an email if need

  - by Gnanam

  Hi, I'm not an expert in writing shell scripts but also I'm looking for a very specific solution. OS: CentOS release 5.2 (Final) I've a Java standalone which keeps writing (all System.out.println) to a log file. For some unknown reason, this Java standalone stops working at some point of time in my server and eventually logs writing also stops working. I want to have a script which checks the last modified date & time of the log file with current date & time in the server. If the time difference exceeds more than 5 minutes, I want to send an email immediately to my recipients list. This way I'll come to know when this Java standalone has stopped working. I'll move this script to crontab and make it run for every 1 minute, so that this whole process is automated. Log file location: /usr/local/logs/standalone.log

• Why isn't this smbmount attempt working?

  - by Max Williams

  I can successfully access one of our local samba shares, which is on a windows pc (called marina) as follows: $ sudo /usr/bin/smbclient \\\\marina\\resource_library <my password> Domain=[MARINA] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager] smb: \> So, that works. I'm now trying to mount the above location (the resource_library folder on marina) to /mnt/resource_library (as a read only folder), but it keeps failing - i've tried a few variations of specifying the location: $ sudo smbmount \\\\marina\\resource_library /mnt/resource_library -o username=max,password=<my password>,r mount error: could not resolve address for marina: No address associated with hostname No ip address specified and hostname not found and $ sudo smbmount //marina/resource_library /mnt/resource_library -o username=max,password=<my password>,r mount error: could not resolve address for marina: No address associated with hostname No ip address specified and hostname not found and both of the above with MARINA instead of marina. It's bound to be some dumb mistake i'm making, can anyone see it? cheers, max
