  • Setting the Timezone with an automated script

    - by Tom
    I'm writing scripts to automate setting up new slicehost installations. In a perfect world, after I started the script, it would just run, with no attention from me. I have succeeded, with one exception. How do I set the timezone, in a permanent (survive reboot) and sane (adjust for standard and daylight savings time, so no just forcing the date) ... manner that doesn't require input from me? Currently, I'm using dpkg-reconfigure tzdata This doesn't seem to have any way to force parameters into it. It demands user input. EDIT: I'm editing here, rather than commenting, since comments don't seem to allow code blocks. Here's the actual code I ended up with, based on Rudedog's comment below. I also noticed that this doesn't update /etc/timezone. I'm not certain who uses that, but in case anybody does, I'm setting that too. TIMEZONE="America/Los_Angeles" echo $TIMEZONE > /etc/timezone cp /usr/share/zoneinfo/${TIMEZONE} /etc/localtime # This sets the time

  • Throughput; capacity planning help for C10K like design

    - by z8000
    I am designing a network service in which clients connect and stay connected -- the model is not far off from IRC less the s2s connections. I could use some help understanding how to do capacity planning, in particular with the system resource costs associated with handling messages from/to clients. There's an article that tried to get 1 million clients connected to the same server [1]. Of course, most of these clients were completely idle in the test. If the clients sent a message every 5 seconds or so the system would surely be brought to its knees. But... How do you do less hand-waving and you know, measure such a breaking point? We're talking about messages being sent by a client over a TCP socket, into the kernel, and read by an application. The data is shuffled around in memory from one buffer to another. Do I need to consider memory throughput ("5 GT/s" [2], etc.)? I'm pretty sure I have the ability to measure the basic memory requirements due to TCP/IP buffers, expected bandwidth, and CPU resources required to process messages. I'm a little dim on what I'm calling "thoughput". Help! Also, does anyone really do this? Or, do most people sort of hand-wave and see what the real world offers, and then react appropriately?

  • Apache configuration to access directory

    - by Felipe Hummel
    I'm on Ubuntu 9.10. My web application is in a directory on my /home/me/app . I want to configure Apache in such a way that I can access my app through a directory. For example: People can access my machine through domain.com. What I would like to do is access my web application (located at /home/me/app) through a directory, using something like: domain.com/myapp. How can I set up the apache configuration for this kind of behavior? Of course, I do not want to move all my application to /var/www/myapp. Thanks

  • Why does my $LD_LIBRARY_PATH get unset when using screen with bash?

    - by UltraNurd
    This is related to http://superuser.com/questions/27376/why-does-my-ld-library-path-get-unset-launching-terminal, but a different set of symptoms. First, /usr/bin/screen is setuid as per the other question. Second, the default shell on this system is /bin/tcsh for various historical reasons, and we're not allowed to chsh to /bin/bash, so I typically run bash manually immediately after login. Third, I almost always use screen, but I want ctrl-a ctrl-c in screen to create a new bash "tab", so I always invoke bash first. That is: {~} $ echo $SHELL /bin/tcsh {~} $ bash [~] echo $SHELL /bin/bash [~] screen -U [~] ...and when reconnecting: {~} $ echo $SHELL /bin/tcsh {~} $ screen -dUr [~] echo $SHELL /bin/bash [~] However, my $LD_LIBRARY_PATH is there in tcsh, there in bash, but empty once I run screen; it is still present if I just run screen from tcsh, but then I get new tcsh "tabs" when I use ctrl-a ctrl-c in screen. Any ideas?

  • Reuse remote ssh connections and reduce command/session logging verbosity?

    - by ewwhite
    I have a number of systems that rely on application-level mirroring to a secondary server. The secondary server pulls data by means of a series of remote SSH commands executed on the primary. The application is a bit of a black box, and I may not be able to make modifications to the scripts that are used. My issue is that the logging in /var/log/secure is absolutely flooded with requests from the service user, admin. These commands occur many times per second and have a corresponding impact on logs. They rely on passphrase-less key exchange. The OS involved is EL5 and EL6. Example below. Is there any way to reduce the amount of logging from these actions. (By user? By source?) Is there a cleaner way for the developers to perform these ssh executions without spawning so many sessions? Seems inefficient. Can I reuse the existing connections? Example log output: Jul 24 19:08:54 Cantaloupe sshd[46367]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:54 Cantaloupe sshd[46446]: Accepted publickey for admin from 172.30.27.32 port 33526 ssh2 Jul 24 19:08:54 Cantaloupe sshd[46446]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:54 Cantaloupe sshd[46446]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:54 Cantaloupe sshd[46475]: Accepted publickey for admin from 172.30.27.32 port 33527 ssh2 Jul 24 19:08:54 Cantaloupe sshd[46475]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:54 Cantaloupe sshd[46475]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:54 Cantaloupe sshd[46504]: Accepted publickey for admin from 172.30.27.32 port 33528 ssh2 Jul 24 19:08:54 Cantaloupe sshd[46504]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:54 Cantaloupe sshd[46504]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:54 Cantaloupe sshd[46583]: Accepted publickey for admin from 172.30.27.32 port 33529 ssh2 Jul 24 19:08:54 Cantaloupe sshd[46583]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:54 Cantaloupe sshd[46583]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:54 Cantaloupe sshd[46612]: Accepted publickey for admin from 172.30.27.32 port 33530 ssh2 Jul 24 19:08:54 Cantaloupe sshd[46612]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:54 Cantaloupe sshd[46612]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:55 Cantaloupe sshd[46641]: Accepted publickey for admin from 172.30.27.32 port 33531 ssh2 Jul 24 19:08:55 Cantaloupe sshd[46641]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:55 Cantaloupe sshd[46641]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:55 Cantaloupe sshd[46720]: Accepted publickey for admin from 172.30.27.32 port 33532 ssh2 Jul 24 19:08:55 Cantaloupe sshd[46720]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:55 Cantaloupe sshd[46720]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:55 Cantaloupe sshd[46749]: Accepted publickey for admin from 172.30.27.32 port 33533 ssh2 Jul 24 19:08:55 Cantaloupe sshd[46749]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:55 Cantaloupe sshd[46749]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:55 Cantaloupe sshd[46778]: Accepted publickey for admin from 172.30.27.32 port 33534 ssh2 Jul 24 19:08:55 Cantaloupe sshd[46778]: pam_unix(sshd:session): session opened for user admin by (uid=0) Jul 24 19:08:55 Cantaloupe sshd[46778]: pam_unix(sshd:session): session closed for user admin Jul 24 19:08:55 Cantaloupe sshd[46857]: Accepted publickey for admin from 172.30.27.32 port 33535 ssh2

  • Case insensitive bash auto-complete

    - by Vitaly Polonetsky
    Is there a way to make the file/dir auto-complete in bash case insensitive? For example I would like to write: /opt/ibm/whatever/test [TAB] And bash will auto-complete it to: /opt/IBM/Whatever/TESTfile Or at least only the last part of test to TESTfile. I know that filesystems are case-sensitive, I just don't want to remember which parts are UPPER-case, I want auto-complete to fix the path for me. And if I have both TESTfile and testfile, just show me both of them like bash does today with auto-complete conflicts.

  • How to get php mail function to work on Debian “squeeze”?

    - by Neel Kamal
    I have installed Apache and PHP5 on my debian server. Firstly I tried it using sendmail. Here is the step by step procedure that I have tried : Step 1: apt-get install sendmail Step 2: /etc/init.d/apache2 restart But this didn't work. Then I tried using external SMTP . My domain is registered on BigRock.I registerd an email address there [email protected] and it gave me the required credentials. On server I installed sSMTP > apt-get install ssmtp > Configured "/etc/ssmtp/ssmtp.conf" file. In the configuration file I added [email protected] mailhub=smtp.fostergen.com:587 (Here I have doubt. I am not sure what to use here. I tried smtp.fostergen.com:587, smtp.fostergen.com:25,mx1.mailhostbox.com :587,mx1.mailhostbox.com:25. I am still not sure what to use here mailhostbox.com. I used mx1.mailhostbox.com as it was the mx entry for my domain on bigrock Here is the screenshot![screenshot of bigrock's email management tool] ) hostname=vs3204.ams2.alvotec.de (I entered the command hostname -f on my server and got it as result ) FromLineOverride=YES UseSTARTTLS=YES [email protected] AuthPass=password provided during email registration on bigrock > edited /etc/ssmtp/revaliases (added " root:[email protected]:mx1.mailhostbox.com :587 " in the last line) > edited php.ini file (sendmail_path = /usr/sbin/ssmtp -t) > /etc/init.d/apache2 restart But this didn't work. After this I tried eSMTP. Steps Performed : > apt-get install esmtp > edited /etc/esmtprc hostname=smtp.fostergen.com:587 username= [email protected] password: password provide by bigrock mda="/usr/bin/procmail -d %T" > linked eSMTP to the legacy Sendmail path by execting the command "ln -s /usr/bin/esmtp /usr/bin/sendmail" > edited php.ini file (/usr/bin/sendmail -t -i) > /etc/init.d/apache2 restart But this technique also failed. I just want to send email to users through php mail function. Kindly help. Where I am going wrong?

  • hosts file seems to be ignored

    - by z4y4ts
    I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.mydomain.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

  • Refresh devices - reconnect CF card drive by script (unplug-plug equivalent)

    - by Chris
    Hello I plug a completely clean CF-card into my USB card-writer. Then I dd a mbr block of 512 bytes size to the device, which contains the partition table and the definition of one partition. Problem: While "fdisk -l /dev/sdx" correctly displays the partition, it happens that there is no device like "/dev/sdx1" after these operations (as it was not present before). Unplugging and plugging the card-writer solves the problem and makes the device(s) appear. Since I use this procedure in a script, manually unplugging and re-plugging is no option whatsoever. Is there a way to "refresh" the devices or to "unplug and re-plug" the drive by script such that /dev/sdx1 appears? Thanks for any help, Chris

  • Running multiple sites on a LAMP with secure isolation

    - by David C.
    Hi everybody, I have been administering a few LAMP servers with 2-5 sites on each of them. These are basically owned by the same user/client so there are no security issues except from attacks through vulnerable deamons or scripts. I am builing my own server and would like to start hosting multiple sites. My first concern is... ISOLATION. How can I avoid that a c99 script could deface all the virtual hosts? Also, should I prevent that c99 to be able to write/read the other sites' directories? (It is easy to "cat" a config.php from another site and then get into the mysql database) My server is a VPS with 512M burstable to 1G. Among the free hosting managers, is there any small one which works for my VPS? (which maybe is compatible with the security approach I would like to have) Currently I am not planning to host over 10 sites but I would not accept that a client/hacker could navigate into unwanted directories or, worse, run malicious scripts. FTP management would be fine. I don't want to complicate things with SSH isolation. What is the best practice in this case? Basically, what do hosting companies do to sleep well? :) Thanks very much! David

  • Is it possible to install all packages from an APT repository?

    - by Kristoffer Hagen
    Is it possible to install all packages from an APT repository? I know it is possible to do it manually, but then you would need to know all the package names, and I don't. Any suggestions? Thanks. Update: Well, you guys are going to kill me for this, but the reason for my madness is that I want to install all the packages from BackTrack into my Ubuntu installation. I really don't like the idea of having it in a VM and having a separate partition for it is even more out of the question. I know that the folks at BackTrack doesn't like it when people leech their repositories, but that's what you get for releasing open source software. Stupid? maybe.. A valid reason? probably not.. Do I still want it? Yes. Another edit: I have now given up on this as it seems impossible to get it to work even by manually installing packages.

  • VNC on Xen failure

    - by BCable
    The following config works and creates a good VM in Xen: # Kernel Setup kernel = "/boot/vmlinuz-2.6.18.8-xenU" # Memory memory = "256" # Disk disk = [ "file:/opt/xen/domains/110/sda1.img,sda1,w", "file:/opt/xen/domains/110/swap.img,sda2,w" ] # container name name = "110" hostname = "boo" # Networking vif = ["type=ieomu, bridge=xenbr0"] # VNC vnc = 1 #vfb = [ 'type=vnc,vncdisplay=2,vnclisten=0.0.0.0,vncpasswd=110' ] # Behavior Settings root = "/dev/sda1" extra = "fastboot" But when I uncomment the VFB line, I get the following error after it hangs for at least 30 seconds: [root@customer 110]# xm create boo.cfg Using config file "./boo.cfg". Error: Device 0 (vkbd) could not be connected. Hotplug scripts not working. Any ideas? Part two of this question: Sometimes it actually works, and a port is opened. When this happens, nmap shows the VNC ports open and I can connect via the VNC client, but it just hangs at "Connection established." and no VNC display shows up. I've tried multiple VNC clients (TightVNC, TightVNC Java Console, RealVNC), but they all fail to connect. Does VNC through Xen require X to be started in order to function? I was under the impression that it would show the console screen, so I'm confused as to why all these issues are occurring. Thanks!

  • PNP4Nagios creates infinite .perfdata files

    - by Kevin Maschke
    at our company we have installed a Icinga together with PNP4Nagios. We've got a rare problem with the perfdata files PNP4Nagios creates. Each couple of weeks, we notice that our icinga server stops working correctly because it runs out of inodes. I've been looking around, and I've noticed that the problem is here: /usr/local/pnp4nagios/var/spool Each couple of weeks, this folder contains over 300k perfdata files of this type: perfdata.1336058870 I think it must be a PNP4Nagios problem, because I think that normally each "X" time, PNP4Nagios should override existing perfdata files to NOT generate new ones. Do you have any idea on what I could change or what I must do to solve this problem? Thanks in advance.

  • ignore ipv6 router advertisements for static addresses with bonded interfaces

    - by boran
    I need to attribute static IPv6 addresses (not use autoconfigured addresses, and ignore router advertisements). This can be done as follows for a standard interface like eth0 iface eth0 inet6 static address myprefix:mysubnet::myip gateway myprefix:mysubnet::mygatewayip netmask 64 pre-up /sbin/sysctl -q -w net.ipv6.conf.$IFACE.autoconf=0 pre-up /sbin/sysctl -q -w net.ipv6.conf.$IFACE.accept_ra=0 However, how can this be done for bonded interfaces? using the "all" interface does not work. Systems is Ubuntu 10.04, 2.6.24-24-server. If one uses the above sysctl command for the bond0, the networking hangs on boot, because /proc/sys/net/ipv6/conf/bond0 does not yet exist and cannot be written to. One the system has booted /proc/sys/net/ipv6/conf/bond0 exist, so one solution after booting is to add the following to /etc/rc.local: /sbin/sysctl -q -w net.ipv6.conf.bond0.autoconf=0 /sbin/sysctl -q -w net.ipv6.conf.bond0.accept_ra=0 /etc/init.d/networking restart and this has the desired effect, the autoconfig v6 address disappears. Seems like a bit of a hack though, are there better solutions?
