• opennms postgres connection slow

  - by krisdigitx

  i am running the opennms application server on a physical server and the database on an ESXi VM. Recently the opennms webconsole has been very slow to load as such i deleted most of the events from the database table, now both servers have no load at all, and the psql connection from the application server to the database server is also very fast, but somehow opennms webconsole is still slow. this is the strace from the opennms process id: 18629 futex(0x2aaac77d8a84, FUTEX_WAIT_PRIVATE, 453, NULL <unfinished ...> 3015 futex(0x2aaabc4a2ee4, FUTEX_WAIT_PRIVATE, 323, NULL <unfinished ...> 10863 futex(0x2aaabbebaa94, FUTEX_WAIT_PRIVATE, 395, NULL <unfinished ...> 25260 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 10859 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 10982 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 3011 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 25260 futex(0x2aaae098fc28, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 10982 futex(0x2aaac0eaf928, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 3011 futex(0x2aaab0cb1728, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 10859 futex(0x2aaac062c328, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 25260 <... futex resumed> ) = 0 10982 <... futex resumed> ) = 0 3011 <... futex resumed> ) = 0 10859 <... futex resumed> ) = 0 25260 futex(0x2aaabc38b6b4, FUTEX_WAIT_PRIVATE, 443, NULL <unfinished ...> 10982 futex(0x2aaabc5d7b94, FUTEX_WAIT_PRIVATE, 99, NULL <unfinished ...> 3011 futex(0x2aaac7c55334, FUTEX_WAIT_PRIVATE, 183, NULL <unfinished ...> 10859 futex(0x2aaabbb8c9d4, FUTEX_WAIT_PRIVATE, 347, NULL <unfinished ...> 10846 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 10846 futex(0x2aaae9022428, FUTEX_WAKE_PRIVATE, 1) = 0 10846 futex(0x2aaabe0030b4, FUTEX_WAIT_PRIVATE, 251, NULL <unfinished ...> 20281 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 14100 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 2925 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 10843 <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) 20281 futex(0x2aaac7e93628, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 14100 futex(0x2aaac04e8c28, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 2925 futex(0x2aaaec085528, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> 10843 futex(0x2aaab20b0528, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> and shows lots of connection timeout??? i think its the connection between the java application and database which is causing issues. any ideas how to troubleshoot this???

• Home server - HP Proliant Microserver - Software and setup - OS on USB stick?

  - by Lloyd Watkin

  I've just purchased a HP ProLiant Microserver for home use. I want to set up with web server, samba shares, the usual stuff. My question is really about system setup. It has an internal USB socket so I've attempted to install a copy of Fedora 14 onto it. I turned off X/Gnome, but it still ran like a pig. I've now put the OS on one of the internal disks (250Gb, 7200rpm), but I was wondering if there was a way to utilise the internal USB to give me better power-saving allowing the hard drives to be shut down when not in use. How would you set this server up? I'd rather not go to the extra cost of an SSD right now, but if that's the best way then so be it.

• probems using ssh from cron

  - by Travis

  I am attempting to automate a script that executes commands on remote machines via ssh. I have public key authentication setup between the machines using ssh-agent. The script runs fine when executed from the command prompt. I suspect my problem is that cron isn't starting the ssh-agent due to it's minimalist environment. Here is the output when I add the -v flag to ssh: debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: gssapi-with-mic debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering public key: /home/<user>/.ssh/id_rsa debug1: Server accepts key: pkalg ssh-rsa blen 149 debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> debug1: Trying private key: /home/<user>/.ssh/id_dsa debug1: Next authentication method: password debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: No more authentication methods to try. Permission denied (publickey,gssapi-with-mic,password). How can I make this work? Thanks!

• Weird noise while scanning, using scanimage and a Canon Lide 35

  - by Manu

  I'm trying to scan a bunch of images, using xsane's scanimage : scanimage --format=tiff --batch --batch-prompt This command scans the first picture perfectly, but as soon as I press enter, the scanner makes a weird noise, and the scanning "arm" moves very, very slowly. If I stop scanimage and start again, it scans normally again. Is there another scanimage option that I need to add? I've checked the man page, but can't see what I'm missing. Edit: the problem seems to be that the scanning "arm" doesn't go back to it's original position after the first scan.

• How to keep groups when pulling with git

  - by mimrock

  I have a staging site that is a working directory of a git repository. How to set up git to let a developer pull out a branch or release without changing the group of the modified files? An example. Let's say I have two developers, robin and david. They are both in git-users group, so initially they can both have write permissions on site.php. -rw-rw-r-- 1 robin git-users 46068 Nov 16 12:12 site.php drwxrwxr-x 8 robin git-users 4096 Nov 16 14:11 .git After robin-server1$ git pull origin master: -rw-rw-r-- 1 robin robin 46068 Nov 16 12:35 site.php drwxrwxr-x 8 robin git-users 4096 Nov 16 14:11 .git And david do not have write permissions on site.php, because the group changed from 'git-users' to 'robin'. From now on, david will get a permission denied, when he tries to pull to this repository.

• How Do I Properly Run OfflineIMAP in a Crontab

  - by alharaka

  Installed Fedora. # cat /etc/redhat_release | awk ' { print F "> " $0; print ""; }' Fedora release 14 (Laughlin) Installed offlineimap from yum, cuz I'm lazy these days. # yum info offlineimap | awk ' { print F "> " $0; print ""; }' Loaded plugins: langpacks, presto, refresh-packagekit Adding en_US to language list Installed Packages Name : offlineimap Arch : noarch Version : 6.2.0 Release : 2.fc14 Size : 611 k Repo : installed From repo : fedora Summary : Powerful IMAP/Maildir synchronization and reader support URL : http://software.complete.org/offlineimap/ License : GPLv2+ Description : OfflineIMAP is a tool to simplify your e-mail reading. With : OfflineIMAP, you can read the same mailbox from multiple : computers.

For instance, you can delete a message on your home : computer, and it will appear deleted on your work computer as : well. OfflineIMAP is also useful if you want to use a mail reader : that does not have IMAP support, has poor IMAP support, or does : not provide disconnected operation. And, lo and behold, every time I run offlineimap and try to redirect output in a crontab, it does not work. Below is my .offlineimaprc.

• Is there any way to recover files in /usr/local directory on Ubuntu?

  - by Ilya

  We are running Ubuntu server on VPS. Some files were removed accidentally by placing unnecessary space this command: rm -r /usr/local <directory to be deleted> I know, that in most cases this directory is used by packages to place some part of their content. Is there any where to recover deleted files and directories? I suppose, that theoretically it should be possible. Some software can look through the list of installed packages, check presence of files in file system and recover or reinstall corrupted packages if their file are missing in /usr/local.

• Postfix tutorial inconsistency

  - by Desmond Hume

  I'm following this tutorial to setup a Postfix/Dovecot mail server with Postfix Admin as a web front end. As regards directory structure for virtual mail users, the author of the tutorial writes: Virtual mail users are those that do not exist as Unix system users. They thus don't use the standard Unix methods of authentication or mail delivery and don't have home directories. That is how we are managing things here: mail users are defined in the database created by Postfix Admin rather than existing as system users. Mail will be kept in subfolders per domain and account under /var/vmail - e.g. [email protected] will have a mail directory of /var/vmail/example.com/me. But when he gives instructions about configuring Postfix Admin, he suggests this to be contained by Postfix Admin's config.inc.php: // Mailboxes // If you want to store the mailboxes per domain set this to 'YES'. // Examples: // YES: /usr/local/virtual/domain.tld/[email protected] // NO: /usr/local/virtual/[email protected] $CONF['domain_path'] = 'NO'; Is there an inconsistency?

• How can I download a copy of an S3 public data set?

  - by tripleee

  i was naively assuming I could do something like s3cmd sync s3://snap-d203feb5 /var/tmp/copy but I seem to have the wrong idea of how to go about this. I cannot even get a simple thing to work; vnix$ s3cmd ls s3://snap-d203feb5 Bucket 'snap-d203feb5': ERROR: Bucket 'snap-d203feb5' does not exist I guess the identifier I have is not for a "bucket" but for a "public data set". How do I go from one to the other? Do I have to start up an EC2 instance and create a bucket for this? How? The instructions at http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/using-public-data-sets.html seem to assume I want to use the data in an EC2 instance, but in this case, I'd just like to browse a bit, at least for a start. By the by, copy/pasting the "US Snapshot ID" causes a nasty traceback from Python; they publish the ID with a weird Unicode (I presume) dash which cannot directly be copy/pasted. Is there a mistake when I copy it? And what's the significance of "US" in there? Can't I use the data outside North America??

• network latency, TCP and UDP packets

  - by user115848

  Hello recently my network has started to cause me lots of problems. I have a cable modem, connected to a tp-link router (with some port forwarding). Everything was working fine then i started to get lots of udp (port 53) "UNREPLIED" logs in the router. Now there are tcp UNREPLIED logs too. This is causing lots of latency and failed connections when trying to connect to different internet sites. Also, we run an openfire server for spark connections, and I believe its causing connectivity issues for some users who are trying to connect using Spark (some people connect fine, others don't). Please see screen shot below for packet logs. It has to be something internally, as I connected straight to the comcast modem and i was able to connect to the internet and various sites as normal. I tried to swap out the router with a different and got the same issue. I scanned both my internal dns servers for viruses or malware and it came up empty. Another anomaly is that when i try to connect to www.cnn.com, i get redirected to the different site. I scanned my own machine for hijacks. Not sure if this is related to the networking issue. Please let me know if you have any ideas for troubleshooting.

• Error when starting qpidd as a service

  - by Sparks

  I have recently swapped from CENTOS 5 to FEDORA 17. Previously I have created my own init.d scripts successfully (albeit not for qpidd) however, in FEDORA I cannot get it to work. I have created the following script (called qpidd) in the init.d directory: #!/bin/bash # # /etc/rc.d/init.d/qpidd # # QPID/AMQP Broker scripts # # # chkconfig: 2345 20 80 # description: QPID/AMQP Broker service # processname: qpidd # pidfile: /var/lock/subsys/qpidd # Source function library. . /etc/init.d/functions SERVICENAME=qpidd start() { echo -n "Starting $SERVICENAME: " daemon qpidd -d & retval=$? touch /var/lock/subsys/$SERVICENAME return $retval } stop() { echo -n "Shutting down $SERVICENAME: " qpidd -q & retval=$? rm -f /var/lock/subsys/$SERVICENAME return $retval } case "$1" in start) start ;; stop) stop ;; status) status qpidd ;; restart) stop start ;; condrestart) [ -f /var/lock/subsys/<service> ] && restart || : ;; *) echo "Usage: $SERVICENAME {start|stop|status|restart" exit 1 ;; esac exit $? After this, I ran chkconfig --add qpidd, however, now when I run sudo service qpidd start I get the following message: Starting qpidd (via systemctl): Job failed. See system journal and 'systemctl status' for details. If I then run systemctl status qpidd I get the following message: Failed to issue method call: Unit name qpidd is not valid. I am now lost, I have search the web and Stack Overflow but cannot find anybody with similar problem, any help or direction to a website that can help would be much appreciated Sparks :)

• Bash command substitution not working as expected

  - by Joe Fruchey

  I'd like to view the last few lines of a file, but I want the columns aligned. Basically, I want to disable wordwrap. This is straightforward with: tail $FILE | cut -c -80 But I'm trying to generalize my script for other users, and I'd like to cut to the actual terminal width, which I can get with: stty size | cut -d" " -f2 So I would imagine that I could just tail $FILE | cut -c -`stty size | cut -d" " -f2` but it doesn't work: stty: standard input: Invalid argument cut: invalid range with no endpoint: - Try `cut --help' for more information. (Same results with the 'new' $() expansion.) Now, if I echo it, it seems fine: echo cut -c -`stty size | cut -d" " -f2` cut -c -103 Am I just missing an escape char? Or is this somehow just not possible? Thanks.

• Removing DS_Store files and variants?

  - by Ron Gejman

  Hi, I am running an Ubuntu 10.04.1 LTS server. Frequently I open up files using AFP from my Mac. Inevitably this created .DS_Store files on the server (although for some reason they are named :2eDS_Store. However, it also creates variants on DS_Store files. These variants are often named similarly to other files in that directory. E.g.: ~$ ls total 60K -rw-r--r-- 1 tarakhovsky 16K 2010-11-30 18:28 :2eDS_Store drwx--S--- 4 tarakhovsky 4.0K 2010-11-08 13:58 :2eTemporaryItems/ lrwxrwxrwx 1 tarakhovsky 15 2010-10-19 17:44 bigdisk -> /media/bigdisk// ... drwxr-xr-x 3 tarakhovsky 4.0K 2010-11-03 18:24 Temporary Items/ drwxr-xr-x 3 tarakhovsky 4.0K 2010-11-30 01:34 tmp/ ... I've disabled creation of DS_Store files using: defaults write com.apple.desktopservices DSDontWriteNetworkStores true so hopefully this won't continue to occur—but I really want to get rid of all of the existing variants of DS_Store files already on the server. Any ideas as to why these variants are being created and how I can get rid of them all?

• Iptables: "-p udp --state ESTABLISHED"

  - by chris_l

  Hi, let's look at these two iptables rules which are often used to allow outgoing DNS: iptables -A OUTPUT -p udp --sport 1024:65535 --dport 53 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -p udp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT My question is: How exactly should I understand the ESTABLISHED state in UDP? UDP is stateless. Here is my intuition - I'd like to know, if or where this is incorrect: The man page tells me this: state This module, when combined with connection tracking, allows access to the connection tracking state for this packet. --state ... So, iptables basically remembers the port number that was used for the outgoing packet (what else could it remember for a UDP packet?), and then allows the first incoming packet that is sent back within a short timeframe? An attacker would have to guess the port number (would that really be too hard?) About avoiding conflicts: The kernel keeps track of which ports are blocked (either by other services, or by previous outgoing UDP packets), so that these ports will not be used for new outgoing DNS packets within the timeframe? (What would happen, if I accidentally tried to start a service on that port within the timeframe - would that attempt be denied/blocked?) Please find all errors in the above text :-) Thanks, Chris
