  • MySQL died during the night on a 12.04.1 Ubuntu

    - by Olivier
    I can't explain why, but somehow during the night, one of my MySQL running on an Ubuntu 12.04.1 box broke. The service is running but I can't login anymore (to SQL), the previous password is not working anymore. It does not looks like the server has been compromised (nothing in /var/auth.log) It looks like some automatic security upgrade (server is configured to perform those) has occured and broke something. The MySQL server has restarted a couple of times in the logs at the time errors started to happen (I get email when CRON task fail). In the logs it complains about an unset root password (I do have cron job running all day using SQL so the password was set & working for months). Anyway I can't login without password either! Do you have any idea of what could have happened? How do I get my databases back? This line looks strange : Nov 6 06:36:12 ns398758 mysqld_safe[6676]: ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ALTER TABLE user ADD column Show_view_priv enum('N','Y') CHARACTER SET utf8 NOT ' at line 1 Here is the full log below : Nov 6 06:36:06 ns398758 mysqld_safe[6586]: Nov 6 06:36:06 ns398758 mysqld_safe[6586]: PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

    - by mattis
    I am trying to connect to a SonicWall VPN that requires the client to fetch IP addresses from the SonicWall DHCP server.

Anyone that can help me with this? I am at my wits end.

  • Binary Log Format in MySQL

    - by amritansu
    Reference manual for MySQL 5.6 states that " Some changes, however, still use the statement-based format. Examples include all DDL (data definition language) statements such as CREATE TABLE, ALTER TABLE, or DROP TABLE. " Does this statement means that even if we have ROW format for binary logs all DDLs will be logged in binary log as statement based? How does this affect replication? Kindly help me to understand this.

I don't find any manual for the 10th version by the way. Do you know if that feature has been removed ? Or do you know where I can find the feature in VMware Workstation 10 (or 9) ?

    Some PDF files produce garbage ("mojibake") when you copy text. This makes it impossible to search them (whatever you search for will not match the garbage). Does anyone have an easy workaround? An example: TEAC TV manual EU2816STF BTW: I am using Adobe Reader - perhaps an alternative viewer might help?

  • Power states in Windows

    - by Kurt
    Does anybody know or have a link to documentation on how the Power Manager of Windows, determines to go to the ACPI power states S1-S4? Are there any settings that can be configured? I know that by default states S1-S3 are disabled in Vista and later (they can be enabled by a group policy). Can Windows cycle through these states while for instance an application is actively running?

  • How to stop a ICMP attack?

    - by cumhur onat
    We are under a heavy icmp flood attack. Tcpdump shows the result below. Altough we have blocked ICMP with iptables tcpdump still prints icmp packets. I've also attached iptables configuration and "top" result. Is there any thing I can do to completely stop icmp packets?

  • How Do I Restrict Repository Access via WebSVN?

    - by kaybenleroll
    I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

Every time I connect to these eg. every time I open Outlook I am prompted to supply username and password in a "Connect to"-dialog and the "Remember password" option has no effect. What can I do to avoid this manual step every time?

  • Preventing Postfix backscattering

    - by Must Do Better
    I am having problems with the Postfix mail server being used for backscattering, I have tried the suggestions in the manual but nothing seems to work. Does anyone know how we can reject any mail from entering the queue if the recipient doesn't match a local recipient rather than send bounce emails? I'm assuming it should be a fairly straight forward change in the configuration files. Just to note I am using Webmin/Virtualmin on the server.

  • Installing Glassfish 3.1 on Ubuntu 10.10 Server

    - by andand
    I've used the directions here to successfully install Glassfish 3.0.1 on an virtualized (VirtualBox and VMWare) Ubuntu 10.10 Server instance without any real difficulty not resolved by more closely following the directions. However when I try applying them to Glassfish 3.1, I seem to keep getting stuck at section 6. "Security configuration before first startup". In particular, there are some differences I noted: 1) There are two keys in the default keystore. The 's1as' key is still there, but another named 'glassfish-instance' is also there. When I saw this, I deleted and recreated them both along with a 'myAlias' key which I was going to use where needed. 2) When turning the security on it seems like part of the server thinks it's on, but others don't. For instances: $ /home/glassfish/bin/asadmin set server-config.network-config.protocols.protocol.admin-listener.security-enabled=true server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command set executed successfully. $ /home/glassfish/bin/asadmin get server-config.network-config.protocols.protocol.admin-listener.security-enabled server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command get executed successfully. $ /home/glassfish/bin/asadmin --secure list-jvm-options It appears that server [localhost:4848] does not accept secure connections.
