  • Postfix unable to create lock file, permission denied

    I thought I had my postfix configuration all set up on my Amazon Ubuntu server but I guess not. I'm trying to set up an admin email account for 3 virtually hosted Apache websites.

  • imapsync - Authentication failed

    I've deployed many Google Apps accounts and have used imapsync a number of times to migrate accounts to Google Apps.

  • error reading keytab file krb5.keytab

    - by Banjer
    I've noticed these kerberos keytab error messages on both SLES 11.2 and CentOS 6.3: sshd[31442]: pam_krb5[31442]: error reading keytab 'FILE: / etc/ krb5. keytab' /etc/krb5.keytab does not exist on our hosts, and from what I understand of the keytab file, we don't need it. Per this kerberos keytab introduction: A keytab is a file containing pairs of Kerberos principals and encrypted keys (these are derived from the Kerberos password). You can use this file to log into Kerberos without being prompted for a password. The most common personal use of keytab files is to allow scripts to authenticate to Kerberos without human interaction, or store a password in a plaintext file. This sounds like something we do not need and is perhaps better security-wise to not have it. How can I keep this error from popping up in our system logs? Here is my krb5.conf if its useful: banjer@myhost:~> cat /etc/krb5.conf # This file managed by Puppet # [libdefaults] default_tkt_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC default_tgs_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC preferred_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC default_realm = FOO.EXAMPLE.COM dns_lookup_kdc = true clockskew = 300 [logging] default = SYSLOG:NOTICE:DAEMON kdc = FILE:/var/log/kdc.log kadmind = FILE:/var/log/kadmind.log [appdefaults] pam = { ticket_lifetime = 1d renew_lifetime = 1d forwardable = true proxiable = false retain_after_close = false minimum_uid = 0 debug = false banner = "Enter your current" } Let me know if you need to see any other configs. Thanks. EDIT This message shows up in /var/log/secure whenever a non-root user logs in via SSH or the console. It seems to only occur with password-based authentication. If I do a key-based ssh to a server, I don't see the error. If I log in with root, I do not see the error. Our Linux servers authenticate against Active Directory, so its a hearty mix of PAM, samba, kerberos, and winbind that is used to authenticate a user.

  • Postfix Send Error: Must Issue STARTTLS command

    Running Ubuntu 12.04 and trying to configure postfix to relay send and receive through GMAIL. Am running into connection issues particularly with TLS.

  • Why does snmp fail to use its own MIBs?

    - by chrisdew
    I've done a fresh install of Ubuntu 12.04LTS, and installed the snmpd and snmp packages. If I type: snmpwalk -m ALL -v2c -c public localhost 1.3 I get swathes of errors, of the form: Cannot adopt OID in SQUID-MIB: cacheClients ::= { cacheProtoAggregateStats 15 } Cannot adopt OID in NET-SNMP-EXTEND-MIB: nsExtendLineIndex ::= { nsExtendOutput2Entry 1 } Cannot adopt OID in NET-SNMP-EXTEND-MIB: nsExtendOutLine ::= { nsExtendOutput2Entry 2 } Cannot adopt OID in UCD-SNMP-MIB: laIndex ::= { laEntry 1 } Cannot adopt OID in UCD-SNMP-MIB: laNames ::= { laEntry 2 } Cannot adopt OID in UCD-SNMP-MIB: laLoad ::= { laEntry 3 } Cannot adopt OID in UCD-SNMP-MIB: laConfig ::= { laEntry 4 } Cannot adopt OID in UCD-SNMP-MIB: laLoadInt ::= { laEntry 5 } Cannot adopt OID in UCD-SNMP-MIB: laLoadFloat ::= { laEntry 6 } Cannot adopt OID in UCD-SNMP-MIB: laErrorFlag ::= { laEntry 100 } Cannot adopt OID in UCD-SNMP-MIB: laErrMessage ::= { laEntry 101 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyRestart ::= { netSnmpNotifications 3 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyShutdown ::= { netSnmpNotifications 2 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyStart ::= { netSnmpNotifications 1 } There a literally hundreds of these. If snmp doesn't even like the distro-included MIBs, what chance to I have of getting my own used? (I get the same form of error with my own MIB, on a different machine, which is why I set up a clean install.) Do other distros have this issue? Is there something obvious that I am overlooking here? Thanks, Chris.

  • XRDP errors when trying to use sesman-x11rdp

    I've just installed Ubuntu 11.10 Desktop on an old laptop of mine and I wanted to set it up so I could remote into it from my windows desktop.

  • Dynamic DNS updates for Linux and Mac OS X machines with a Windows DNS server

    - by DanielGibbs
    My network has a Windows machine running Server 2008 R2 which provides DHCP and DNS. I'm not particularly familiar with Windows domains, but the domain is set to home.local and that is the DNS domain name provided with DHCP leases. Everything works fine for Windows machines, they get the lease and update the server with their hostname and the server creates a DNS records for windowshostname.home.local. I am having problems obtaining the same functionality on Linux (Debian) and Mac OS X (Mountain Lion) machines. They receive DHCP just fine, but DNS entries are not being created on the server for them. On the Mac OS X machine, hostname gives an output of machostname.local, and on the Linux machine hostname --fqdn also gives an output of linuxhostname.local. I'm assuming that the server is not creating DNS entries because the domain does not match that of the server (home.local). I don't want to statically configure these machines to be part of the home.local domain, I just want them to pick it up from DHCP and be able to have entries in the DNS server. How should I go about doing this?

  • Fix ACPI DSDT of Amilo Pa 1538

    - by kayahr
    I have a Fujitsu-Siemens Amilo Pa 1538 laptops and installed Ubuntu 10.04 on it (Kernel 2.6.32). Main problem is that the fans of the notebook are always on even when the temperature is low. Another problem is that the display brightness can not be adjusted. Since some years I use Dell laptops and never experienced any ACPI problems so I thought that it is no longer needed to fix ACPI tables but now I have this crap of a laptop and I think I have to do it. Unfortunately I need some help repairing the DSDT. The dsdt.dat and dsdt.dsl of the laptop can be found here: http://www.ailis.de/~k/permdata/20100420/dsdt/ Compiling the DSDT gives the following output: # iasl -sa dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler version 20090521 [Jun 30 2009] Copyright (C) 2000 - 2009 Intel Corporation Supports ACPI Specification Revision 3.0a dsdt.dsl 81: Method (\_WAK, 1, NotSerialized) Warning 1080 - ^ Reserved method must return a value (_WAK) dsdt.dsl 207: Method (_L10, 0, NotSerialized) Warning 1087 - ^ Not all control paths return a value (_L10) dsdt.dsl 2861: Method (NVIF, 3, NotSerialized) Warning 1087 - ^ Not all control paths return a value (NVIF) dsdt.dsl 4551: Store (\_SB.PCI0.LPC0.PMRD (0xFA), Local0) Warning 1099 - Statement is unreachable ^ ASL Input: dsdt.dsl - 4962 lines, 162828 bytes, 2300 keywords AML Output: dsdt.aml - 17627 bytes, 591 named objects, 1709 executable opcodes Compilation complete. 0 Errors, 4 Warnings, 0 Remarks, 519 Optimizations Anyone here with DSDT experience who can help me fixing the DSDT?

  • OTRS upgrade 3.0 to 3.1 fails

    - by Valentin0S
    Today I've started upgrading OTRS from version 2.3 to 2.4 , 2.4 to 3.0 and 3.0 to 3.1.

  • Unable to install PHP-FPM on Apache (Failed to connect to FastCGI server)

    - by Nyxynyx
    I have been having problem installing php-fpm for use with apache2-mpm-worker. This is the guide that I am following. According to the guide's Step 5, Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -host 127.0.0.1:9000 -pass-header Authorization However I cannot find php5-fcgi at /usr/lib, but only /usr/bin/php5-cgi and /usr/bin/php-cgi, which I am not sure if they are the same. So I changed the lines in Step 5 to: Alias /php5-fcgi /usr/bin/php5-fcgi FastCgiExternalServer /usr/bin/php5-fcgi -host 127.0.0.1:9000 -pass-header On restarting Apache, it's logs gave the errors: [notice] caught SIGTERM, shutting down [alert] (4)Interrupted system call: FastCGI: read() from pipe failed (0) [alert] (4)Interrupted system call: FastCGI: the PM is shutting down, Apache seems to have disappeared - bye [notice] Apache/2.2.22 (Ubuntu) mod_fastcgi/mod_fastcgi-SNAP-0910052141 configured -- resuming normal operations [notice] FastCGI: process manager initialized (pid 16348) And on loading the index page [error] [client 10.0.2.2] (111)Connection refused: FastCGI: failed to connect to server "/usr/bin/php5-cgi": connect() failed [error] [client 10.0.2.2] FastCGI: incomplete headers (0 bytes) received from server "/usr/bin/php5-cgi" [error] [client 10.0.2.2] File does not exist: /var/www/mydomain/public/favicon.ico Question: Any idea why php5-fcgi is missing, and how should this problem be fixed?

  • Filesystems for webserver with SATA and Solid State disk,

    - by Jorisslob
    We have just ordered a new webserver with 120 Gb solid state disk and a SATA disk. I am trying to plan ahead what sort of filesystem to use. This system will be running Linux, Apache/Tomcat to host java services. The main service is a system where people can upload reasonably large files (in the order of 100 Mb, images, image stacks and video), which people will be able to annotate and which will be sent to a database server when annotation is complete. Thus far, I plan to put most of the utility programs of the operating system om the SSD and put the large media files there. The SATA disks will hold the less volitile data like apache, tomcat and the servlets. For filesystems I have considered going for the stable EXT3 because I hear that it is best supported. The downside seems to be that it not the ideal choice for large files. That is why I am leaning towards using XFS for the SSD and EXT3 for the SATA. My questions are: 1) Does this sound like a reasonable setup? 2) What filesystems would you recommend for the SSD and for the SATA? Thanks

  • What kind of “sysadmin stuff” should I show to students during a talk?

    - by Gregory Eric Sanderaon
    A teacher asked me If I could talk about my job as a linux sysadmin in his class. The course is called "Introduction to Operating systems" and i've been given 45 minutes to talk. The students are beginning their second year, so they've had a bit of experience with programming in different languages. What i'm like to do is show a series of hands-on examples of the kinds of things I do on a regular basis. I've already got a few ideas jotted down, but I'm afraid that they might be either too advanced or too simple for the students to appreciate. Another concern is that a topic might be too long to explain and use too much time overall. Here are a few ideas : Program deployment using version control (git in my case) filtering apache logs using grep, awk, uniq, tail A couple of bash scripts that i've made for various stuff on servers live montitoring (htop, iotop, iptraf) creating databases and assigning roles in mysql/postgresql So, are these ideas any good ? Do you have better ideas ? are the ideas too simple and should I go for more "advanced" stuff ?

  • Launching firefox on remote server causes local firefox to start instead

    - by terdon
    Right, this is strange. I am connecting from my laptop (LMDE) to a remote host (SUSE linux enterprise) using ssh -X. I want to launch a firefox instance running on the remote server so I can have access to webpages on a private network. User@RemoteMachine $ which -a firefox /usr/bin/firefox User@RemoteMachine $ /usr/bin/firefox --version Mozilla Firefox 2.0.0.2, Copyright (c) 1998 - 2007 mozilla.org User@LocalMachine $ which -a firefox /usr/bin/firefox User@LocalMachine $ /usr/bin/firefox --version Mozilla Firefox 14.0.1 Now, if firefox is not running on the local machine, everything goes as expected and executing firefox on the remote machine causes a firefox (v 2.0) window running on the remote machine to show up. However, if firefox is running on the local machine a second window of firefox 14.0.1 running on the local machine appears. I have checked top in both machines. In the 2nd case, a firefox process briefely appears on the remote machine and then disappears when the local version of firefox is launched. My questions are the following: What gives? How/why can firefox connect to its existing instance on the local machine? The remote machine appears to have access to the local machine. It, in fact, appears to have the right to execute programs on my local machine. Am I missing something or is this just weird? Is this not a security risk?

  • Webmin / Virtualmin running php as www-data, is locked out of viewing .htaccess and writing

    - by Kirill
    I've asked this on the virtualmin forums, but haven't had any help from there. Recently, "something" happened and it seems that the apache service has gone a bit weird. What it does: it runs all apache traffic as www-data and sometimes spawns the php5-cgi process as www-data, this is a problem because all the domain users own their directories and default permissions don't let www-data write to these folders (file uploads are dead) or read .htaccess (permalinks are broken in wordpress). I've googled this for about a week straight now, tried pretty much everything I could find and achieved nothing. The only thing that I think might actually be the cause of all this is this page: http:// - i.imgur.com/NYW3x.png (got shut down by the spam filter) So I figured if I set it to "default", this might magically start working again, but all it does is "crash" apache (all websites timeout). I figure it's something to do with the "mpm" module or something, but I can't find anything relevant in the settings to modify for it to work. Can someone please point me in the right direction? System info: Webmin version 1.580 Kernel and CPU Linux 2.6.35.4-rscloud on x86_64 Virtualmin version 3.90.gpl GPL Ubuntu 10.04 LTS (Lucid) A couple screenshots of top http://i.imgur.com/U2DTK.png http://i.imgur.com/sNPKs.png

  • Bind9 configured to start at boot, has to be started manually

    - by antik
    I've configured bind9 on my system and it works great when it runs. It's currently configured to be run at runlevel 2 by setting: $ sudo update-rc.d bind9 enable 2 This appears to have done its work: $ tree -f /etc/rc?.d | grep -e ".*bind9$" |-- /etc/rc0.d/K85bind9 -> ../init.d/bind9 |-- /etc/rc2.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc3.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc4.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc5.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc6.d/K85bind9 -> ../init.d/bind9 Booting the system, I believe I am at runlevel 2: $ runlevel N 2 Given the above configuration, when the system is rebooted, bind does not come up. Only on occasion, for some reason, can I resolve hostnames immediately after startup. Far more often than not however, I cannot. I can interrogate the service's status: $ sudo /etc/init.d/bind9 status * could not access PID file for bind9 When the service doesn't start, I can start it successfully via a terminal by issuing $ sudo /etc/init.d/bind9 start And it works great from then on. Loopback configuration: $ ifconfig lo lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1872 errors:0 dropped:0 overruns:0 frame:0 TX packets:1872 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:220205 (220.2 KB) TX bytes:220205 (220.2 KB) Do I have my startup misconfigured? (I'm used to Gentoo so Ubuntu's model is still a little new to me) I'm not seeing any log indication of a failed attempt to start at boot in syslog. Is there someplace else I should be looking? What else should I look into to get bind working at startup?

  • Experiences with BIRD for BGP?

    - by Shtééf
    We're currently using Quagga with Debian Linux to run a full table BGP router. The set-up has been dead simple up to now, but we've come to a point where I have to reconfigure the router quite a bit, and want to tighten things up. I've never really understood Quagga, and always found its documentation to be lacking. It appears to be mimicking Cisco, of which I only have basic understanding. BIRD has caught my eye recently. The couple of articles / presentations I found promote it as lightweight and more responsive under stress compared to Quagga. And it actually seems to have very decent documentation. So I'd like to know: Who's running BIRD right now, and in what kind of set-up? How is it stability-wise? I've read about it running in a couple of sites in production. Let's say I don't care at all for a Cisco-feel to configuration. How is configuration, maintainance, monitoring, etc. of BIRD in general? And any other notable experiences you may have with it.

  • Unconvert Text File from Binary Format

    - by Hammer Bro.
    I've got a rather large CSV file (~700MB) which I know to consist of lines of 27-character alpha-numeric hashes; no commas or anything fancy. Somehow, during its migration from Windows to Linux (via winSCP and then a few regular SCPs), it has converted into some kind of binary format I am unfamiliar with. If I open the file in vi, everything appears fine, and it says [converted] at the bottom, although I know it's not a line endings issue (and dos2unix doesn't help). If I 'head' the file, it looks proper except for a "ÿþ" at the beginning of the first line. If I open up the file in nano, however, I see the "ÿþ" at the start and then "^@" before every character (even newlines and EoF). If I try to re-save or copy the file (say via: head file.csv short.txt), this special encoding is preserved. I copied the first ten lines out of vi (which displays it properly) into my Windows clipboard via my SSH client, then pasted it into a new text file, test.txt. This file is visually identical when opened in vi (and similar through 'head', minus the "ÿþ"), although it's roughly half of the filesize. Additionally, file test.txt test.txt: ASCII text file short.txt short.txt: I have no idea what format this once-text file got converted to (it's notoriously hard to search the internet for symbols), but surely there must be some way to convert it back. Any ideas?

  • Bridging Virtual Networking into Real LAN on a OpenNebula Cluster

    - by user101012
    I'm running Open Nebula with 1 Cluster Controller and 3 Nodes. I registered the nodes at the front-end controller and I can start an Ubuntu virtual machine on one of the nodes. However from my network I cannot ping the virtual machine. I am not quite sure if I have set up the virtual machine correctly. The Nodes all have a br0 interfaces which is bridged with eth0. The IP Address is in the 192.168.1.x range. The Template file I used for the vmnet is: NAME = "VM LAN" TYPE = RANGED BRIDGE = br0 # Replace br0 with the bridge interface from the cluster nodes NETWORK_ADDRESS = 192.168.1.128 # Replace with corresponding IP address NETWORK_SIZE = 126 NETMASK = 255.255.255.0 GATEWAY = 192.168.1.1 NS = 192.168.1.1 However, I cannot reach any of the virtual machines even though sunstone says that the virtual machine is running and onevm list also states that the vm is running. It might be helpful to know that we are using KVM as a hypervisor and I am not quite sure if the virbr0 interface which was automatically created when installing KVM might be a problem.

  • How to make sysctl network bridge settings persist after a reboot?

    - by user183394
    I am setting up a notebook for software demo purpose. The machine has 8GB RAM, a Core i7 Intel CPU, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit. The notebook is used as a KVM host and runs a few KVM guests. All such guests use the virbr0 default bridge. To enable them to communicate with each other using multicast, I added the following to the host's /etc/sysctl.conf, as shown below net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 Afterwards, following man sysctl(8), I issued the following: sudo /sbin/sysctl -p /etc/sysctl.conf My understanding is that this should make these settings persist over reboots. I tested it, and was surprised to find out the following: root@sdn1 :/proc/sys/net/bridge# more *tables :::::::::::::: bridge-nf-call-arptables :::::::::::::: 1 :::::::::::::: bridge-nf-call-ip6tables :::::::::::::: 1 :::::::::::::: bridge-nf-call-iptables :::::::::::::: 1 All defaults are coming back! Yes. I can use some kludgy "get arounds" such as putting a /sbin/sysctl -p /etc/sysctl.conf into the host's /etc/rc.local but I would rather "do it right". Did I misunderstand the man page or is there something that I missed? Thanks for any hints. -- Zack
