  • Postfix mail server: can't connect via POP/IMAP

    - by MelkerOVan
    I've followed this guide on setting up a mail server on my dedicated server. I've been able to send mails from the php application I'm using and the linux commandline (using telnet, php, etc). The problem is that I cannot connect to the server via IMAP/POP which I've setup using Courier. I've tried using thunderbird but it complains that the username or password is wrong. I doubt it is the username/password but I don't know how to trouble shoot this. Edit: Here's the messages in mail.log: Jan 9 22:43:38 mail authdaemond: received auth request, service=imap, authtype=login Jan 9 22:43:38 mail authdaemond: authmysql: trying this module Jan 9 22:43:38 mail authdaemond: SQL query: SELECT id, crypt, "", uid, gid, home, "", "", name, "" FROM users WHERE id = '[email protected]' AND (enabled=1) Jan 9 22:43:38 mail authdaemond: password matches successfully Jan 9 22:43:38 mail authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: authmysql: clearpasswd=<null>, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: Authenticated: clearpasswd=peter, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail imapd: chdir Maildir: No such file or directory

  • openvpn TCP/UDP slow SSH/SMB performance

    - by Petr Latal
    I have question about strange behavior of my openVPN configuration on Debian lenny. I have 2 server configs (one proto tcp-server based and one proto udp based). ISP bandwidth is 7Mbit/7Mbit. When I uses proto tcp-server my download server rate is fine around 6,4 Mbit/s, but upload rate is about 3Mbit/s. When I uses proto udp, my download server rate is around 3Mbit/s and upload rate around 6,4Mbit/s. I tried to handle the MTU, MSSFIX and cipher on/off on server and client configs to synchronize rates, but without solution. Here is TCP based SERVER config: mode server tls-server port 1194 proto tcp-server dev tap0 ifconfig 11.10.15.1 255.255.255.0 ifconfig-pool 11.10.15.2 11.10.15.20 255.255.255.0 push "route 192.168.1.0 255.255.255.0" push "dhcp-option DNS 192.168.1.200" push "route-gateway 11.10.15.1" push "dhcp-option WINS 192.168.1.200" route-up /etc/openvpn/routeup.sh duplicate-cn ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh2048.pem log-append /var/log/openvpn.log status /var/run/vpn.status 10 user nobody group nogroup keepalive 10 120 comp-lzo verb 3 script-security 3 plugin /usr/lib/openvpn/openvpn-auth-pam.so system-auth persist-tun persist-key mssfix cipher BF-CBC Here is UDP based SERVER config: port 1194 proto udp dev tun0 local xx.xx.xx.xx server 11.10.15.0 255.255.255.0 ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh2048.pem log-append /var/log/openvpn.log status /var/run/vpn.status 10 user nobody group nogroup keepalive 10 120 comp-lzo verb 3 duplicate-cn script-security 3 plugin /usr/lib/openvpn/openvpn-auth-pam.so system-auth persist-tun persist-key tun-mtu 1500 mssfix 1212 client-to-client ifconfig-pool-persist ipp.txt Here is TCP/UDP based windows CLIENT config: remote xx.xx.xx.xx --socket-flags TCP_NODELAY tls-client port 1194 proto tcp-client #proto udp dev tap #dev tun pull ca ca.crt cert latis.crt key latis.key mute 0 comp-lzo adaptive verb 3 resolv-retry infinite nobind persist-key auth-user-pass auth-nocache script-security 2 mssfix cipher BF-CBC

  • MS SQL - Problem running SQL Server Agent Job via service account credentials

    - by molecule
    There are 5 steps in this job. First job is an SSIS Package store, second to fifth are file system jobs. We configured all jobs to use Windows Authentication.

  • What device can create wireless network while connecting to an ethernet router

    - by Nicolo
    Hi, I have access to an ethernet port of a wireless router. I simply connect my laptop to it via an ethernet cable. There are a total of four such ports on the wireless router. Now I want to connect a device (a wireless access point? wireless bridge? wireless switch?) via an ethernet cable to one of the other ethernet ports of the router. I want this device to act as a kind of wireless switch - it should "split" the ethernet connection coming from the router to two or more computers that connect to this device via a wireless. Basically, I have a wireless router with its wireless function switched off. I don't know the password for that router so can't activate the wireless function. Don't know the password of the ISP either. The only thing I can do is to connect via ethernet cable to the wireless router and this does not require a password. Now I want to use that connection and build a wireless upon it. What kind of device do I need? I am not really very well informed about network management and find the descriptions "wireless access point", "wireless bridge", "wireless switch" confusing. I know what an ethernet switch is - what I need is a device which would do the same but by allowing the clients to connect to it via a wireless. What kind of device would do that? Any recommendations about specific products?

  • Jetty - 401 Unauthorized when using basic authentication

    - by JP.
    I am running SOLR on jetty in Ubuntu (a bitnami VM, if that helps) and am trying to lock down access to both the admin pages and the update/delete/etc. pages using basic authentication. When I attempt to connect to the admin console via a web browser I am prompted for a user name and password, but the username and password I use simply does not work.

  • Why are my Windows 7 updates continuously failing?

    - by Chris C.
    I'm an advanced level user here with an odd issue. I have two Windows Updates that are failing to install, every single time. I'm getting a mysterious "Code 1" error on both updates, an error for which I'm having difficulty finding a solution.

  • A network-related or instance-specific error occurred while establishing a connection to SQL Server

    - by sf
    Hi, I'm getting the following error when trying to load an Asp.NET MVC App on IIS 7 with Sql Server 2008 Express. The App uses Linq to SQL. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've done some searching and all answers point to enabling TCP connections in Sql Server Configuration which I have done to no avail. The connection string I am using is: Server=SERVERNAME\SQLEXPRESS;Database=DBName;Integrated Security=true The catch. I have another app that already could talk to the Sql Server just fine. Even before playing around with the Sql Server Configuration Settings. The other app uses the following connectionstring: Data Source=SERVERNAME\SQLEXPRESS;Initial Catalog=OtherDbName;Integrated Security=True;Persist Security Info=False;Connect Timeout=120 I've tried this connectionstring on the app that isn't working and it still doesn't work. Please help. I think i'm about to go crazy

  • Create SAMBA node trust relationship to Windows 2003 PDC server

  • Remotely managing Scheduled Tasks on another computer: Access Denied

    - by Eptin
    I need to remotely create new scheduled tasks from a Windows 7 computer in my company (which according to this Microsoft TechNet article I should be able to do. http://technet.microsoft.com/en-us/library/cc766266.aspx ) From within Task Scheduler, on the menu I click Action Connect to another Computer. I browse for the remote computer's name (I use Check Names to verify that the name is correct) and then I check 'Connect as another user' and enter \Administrator and the local admin password. Whenever I try this, I get the error message Task Scheduler: You do not have permission to access this computer Firewall isn't the problem I am able to use Remote Desktop with this username & password combo, so I would expect it to work when remotely managing as well. The remote computer has firewall exceptions for Remote Scheduled Tasks Management, Remote Service Management, and Remote Desktop among other things. Heck, I even tried turning off the firewall for that individual computer and it still didn't work. More details: I have administrative remote access to several other Windows 7 Enterprise computers, though I log in as the local Administrator (whose administrative rights are only recognized by that local machine, not by the domain). The computer I am managing from is on the domain, and also has administrative rights that are recognized on the domain. More experimentation: If I go the other way around and remote-desktop into the other machine and from there open task scheduler then 'connect to another computer', I am able to connect back to my main computer using the username & password that is recognized by an administrator on the domain, and successfully schedule a task on my main computer. So it's not a company firewall issue that's preventing anything from working. The only permissions requirement Microsoft talks about is "The user credentials that you use to connect to the remote computer must be a member of the Administrators group on the remote computer". I'm logging in as an Administrator on each of the local machines, so why doesn't it work?

  • Fedora 16 can connect to samba share using smbclient but not in nautilus 3.2.1

    - by Nathan Jones
    I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus. I know that there can be problems with SELinux and Samba, so I created a file called booleans.local that contains samba_enable_home_dirs=1.

  • Help diagnosing Likewise Open Active Directory authentication problem

    - by purpletonic
    I have two servers which were up until recently authenticating against the companies Active Directory Domain controller. I believe a recent change to the Active Directory administrator password caused the servers to stop authenticating against AD. I tried to add the servers back to the domain using the command: domainjoin-cli join example.com adusername this seemed to work without complaints, but when I try to login via ssh with my domain account, I get an invalid password error. When I run the command: lw-enum-users it prints all of the domain users, and looking up my own account, I see that it is valid and my password hasn't expired. I also ran lw-get-status and received the following: LSA Server Status: Agent version: 5.0.0 Uptime: 0 days 3 hours 35 minutes 46 seconds [Authentication provider: lsa-activedirectory-provider] Status: Online Mode: Un-provisioned Domain: example.com Forest: example.com Site: Default-First-Site-Name Online check interval: 300 seconds \[Trusted Domains: 1\] \[Domain: EXAMPLE\] DNS Domain: example.com Netbios name: EXAMPLE Forest name: example.com Trustee DNS name: Client site name: Default-First-Site-Name Domain SID: S-1-5-24-1081533780-4562211299-822531512 Domain GUID: 057f0239-7715-4711-e64b-eb5eeed20e65 Trust Flags: \[0x001d\] \[0x0001 - In forest\] \[0x0004 - Tree root\] \[0x0008 - Primary\] \[0x0010 - Native\] Trust type: Up Level Trust Attributes: \[0x0000\] Trust Direction: Primary Domain Trust Mode: In my forest Trust (MFT) Domain flags: \[0x0001\] \[0x0001 - Primary\] \[Domain Controller (DC) Information\] DC Name: dc1.example.com DC Address: 10.11.0.103 DC Site: Default-First-Site-Name DC Flags: \[0x000003fd\] DC Is PDC: yes DC is time server: yes DC has writeable DS: yes DC is Global Catalog: yes DC is running KDC: yes [Authentication provider: lsa-local-provider] Status: Online Mode: Local system Anyone got any ideas what might be occurring?

  • Folder Redirection Issues - Freezing, Strange Warnings

    - by JCardenas
    I have Folder Redirection set up in a test environment for a couple accounts. I have followed the instructions for setting up the folder security settings here, and I can confirm that folders are created automatically by the system with the correct security settings when a user logs in. The GPO has been configured to automatically move user files up to the redirected folders, and this is working properly. Problems start occurring when a Windows 7 PC is in use. It is rare, but Explorer will lock up when performing a file write operation (move/copy/save from application). This results in the entire system being unusable, with only a hard reset resolving it (Task Manager doesn't start, the "three finger salute" does nothing, apps stop working). The mouse functions, but clicks do nothing. The other issue is that occasionally when copying/creating/modifying files a dialog box will pop up with the message "You need permission to perform this action. You require permission from XYZ\cardenas to make changes to this folder." The folder that was created by copying an existing one has the correct security settings and lists me as the owner. My company will not be implementing Folder Redirection on XP, since we are making a "clean break" with implementing new technologies with the Windows 7 rollout, so this behavior has not been - nor will be - checked for in XP. Thanks in advance for your help!

    Hi, When I run sshpass -p 'mypass' sshfs 'root'@'68.19.40.16':/ '/dir' -o StrictHostKeyChecking=no,debug It successfully mounts but it runs on foreground.

  • How to give a user NTFS rights to a folder, via Powershell

    - by Don
    I'm trying to build a script that will create a folder for a new user on our file server. Then take the inherited rights away from that folder and add specific rights back in. I have it successfully adding the folder (if i give it a static entry in the script), giving domain admin rights, removing inheritance, etc...but i'm having trouble getting it to use a variable I set as the user. I don't want there to be a static user each time, I want to be able to run this script, have it ask me for a username, it then goes out and creates the folder, then gives that same user full rights to that folder based on the username i've supplied it. I can use Smithd as a user, like this: New-Item \\fileserver\home$\Smithd –Type Directory But can't get it to reference the user like this: New-Item \\fileserver\home$\$username –Type Directory Here's what i have: Creating a new folder and setting NTFS permissions. $username = read-host -prompt "Enter User Name" New-Item \\\fileserver\home$\$username –Type Directory Get-Acl \\\fileserver\home$\$username $acl = Get-Acl \\\fileserver\home$\$username $acl.SetAccessRuleProtection($True, $False) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Domain\Domain Admins","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Domain\"+$username,"FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) Set-Acl \\\fileserver\home$\$username $acl I've tried several ways to get it to work, but no luck. Any ideas or suggestions would be welcome, thanks.

  • Whitelist IP from google-authenticator in sshd pam

    - by spudwaffle
    My Ubuntu 12.04 server uses the google-authenticator pam module to provide two step authentication for ssh. I need to make it so that a certain IP does not need to type the verification code. The /etc/pam.d/sshd file is below: # PAM configuration for the Secure Shell service # Read environment variables from /etc/environment and # /etc/security/pam_env.conf. auth required pam_env.so # [1] # In Debian 4.0 (etch), locale-related environment variables were moved to # /etc/default/locale, so read that as well. auth required pam_env.so envfile=/etc/default/locale # Standard Un*x authentication. @include common-auth # Disallow non-root logins when /etc/nologin exists. account required pam_nologin.so # Uncomment and edit /etc/security/access.conf if you need to set complex # access limits that are hard to express in sshd_config. # account required pam_access.so # Standard Un*x authorization. @include common-account # Standard Un*x session setup and teardown. @include common-session # Print the message of the day upon successful login. session optional pam_motd.so # [1] # Print the status of the user's mailbox upon successful login. session optional pam_mail.so standard noenv # [1] # Set up user limits from /etc/security/limits.conf. session required pam_limits.so # Set up SELinux capabilities (need modified pam) # session required pam_selinux.so multiple # Standard Un*x password updating. @include common-password auth required pam_google_authenticator.so I've already tried adding a auth sufficient pam_exec.so /etc/pam.d/ip.sh line above the google-authenticator line, but I can't understand how to check an IP adress in the bash script.

  • OpenLDAP, howto allow both secure (TLS) and unsecure (normal) connections?

    - by Mikael Roos
    Installed OpenLDAP 2.4 on FreeBSD 8.1. It works for ordinary connections OR for TLS connections. I can change it by (un)commenting the following lines in slapd.conf. # Enable TLS #security ssf=128 # Disable TLS security ssf=0 Is there a way to allow the clients to connect using TLS OR no-TLS? Can the ldap-server be configured to support both TLS connections and no-TLS connections? Tried to find the information in the manual, but failed: http://www.openldap.org/doc/admin24/access-control.html#Granting%20and%20Denying%20access%20based%20on%20security%20strength%20factors%20(ssf) http://www.openldap.org/doc/admin24/tls.html#Server%20Configuration Tried to read up on 'security' in manualpage for ldap.conf, didn't find the info there either. I guess I need to configure the 'secure' with some negotiation mechanism, "try to use TLS if client has it, otherwise continue using no-TLS". Connecting with a client (when slapd.conf is configure to use TLS): gm# ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts ldap_bind: Confidentiality required (13) additional info: TLS confidentiality required gm# ldapsearch -Z -x -b '' -s base '(objectclass=*)' namingContexts (this works, -Z makes a TLS connection) So, can I have my ldap-server supporting client connections using TLS and ordinary (no-TLS) connections? Thanx in advance.

  • After update, suddenly lost ability to access Windows Server 2008 R2 shares from Windows XP clients

    - by Knute Knudsen
    Today I lost the ability to see my Windows Server 2008 R2 shares from any of my 3 Windows XP machines in my small office. The 5 Win7 machines haven't been affected (they are still able to browse/access the 2008 server), but none of my WinXP machines can access the 2008R2 server anymore. Yesterday (and for the previous year) everything was working fine. I do not have a domain setup. I can still access Win7 shares from WinXP clients. Browsing the server logs, I see that the following update was installed last night: > Installation Ready: The following updates are downloaded and ready for > installation. This computer is currently scheduled to install these > updates on ?Thursday, ?November ?15, ?2012 at 3:00 AM: > - Security Update for Windows Server 2008 R2 x64 Edition (KB2761226) > - Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2729452) > - Windows Malicious Software Removal Tool x64 - November 2012 (KB890830) > - Cumulative Security Update for Internet Explorer 9 for Windows Server 2008 R2 x64 Edition (KB2761451) It seems likely that something was changed in last night's update, but so far I haven't seen anything on microsoft.com to prove it. I did hear that XP is reaching the end of the road soon. Any ideas?

  • Virtual Machines and Automatic Software Updates

    - by Zian Choy
    It's obvious that one's main computer should always be have all the latest security patches and most people don't blink an eye when Microsoft Update installs non-security updates. In the land of virtual machines, I've run into 2 problems with automatic updates: The virtual machines are only run when needed. Only Windows virtual machines seem to patch themselves. To elaborate on #1, I generally make a virtual machine with a purpose in mind. For example, when I needed an old copy of Internet Explorer to reproduce a bug in RSS Bandit, I had a Virtual PC named RSS Bandit. The machine only stayed running for a few minutes at a time. Consequently, there is no downtime for the machine to download updates at 3 AM. To elaborate on #2, I've noticed that if I haven't run a Windows virtual machine in a while, then the moment I log in, the computer frantically downloads updates and within seconds, if I click the Start button, there is a little orange shield next to the "Shutdown" button. However, I ran a freshly created Ubuntu VM for several hours today with hundreds of updates pending and it seemed to never download any of them or install any of them. Is there any reason to be concerned about running VMs with dozens of security holes? If I should be concerned, then is there any way to get Ubuntu to download and install updates rather than just advertising a long list of updates to download next century? I've already tried telling Ubuntu to automatically download and install updates.

  • Run FTP session from bash script

    - by Adam Salkin
    I'm trying to write a BASH script to test if an FTP site that I own is running. I therefore want the bash script to connect to the FTP site, log in with a dummy account and redirect the output to a file that I can then grep to confirm that the login succeeded. (I know that putting user/pass in a file is not recommended, but this dummy account is chrooted to one empty directory and can't escape to the shell, and in any case I'm the only user who can login to a shell prompt.) I'm using the BASH shell on Ubuntu. I created a file called "ftp-dummy" which looks like this username password And I then did this from the prompt: adam$ ftp my.ftpsite.com < ftp-dummy This does not work - I don't see the normal welcome message and the output is: Password:Name (my.ftpsite.com:adam) : I tried removing the space between the < and the filename - same result. If I redirect the output to a testfile, the testfile shows: Name (my.ftpsite.com:adam): ?Invalid command And I still get a Password prompt on STDOUT I also tried using echo and get the same result: echo -e "username \npassword \n" | ftp my.ftpsite.com I don't see why I'm not seeing the normal welcome message or why the input is not being read from the file. Any help would be much appreciated. Thanks, Adam

  • Group Policy GPO not 'seen' at client

    - by fukawi2
    I have a new OU (natorg.local\NATO\Users) that I am trying to apply GP to. I have created a new user in this OU, and linked the 3 GPO's to this OU: DESKTOP - Folder Redirection (AppData) DESKTOP - Folder Redirection (Desktop) DESKTOP - Folder Redirection (Documents) Hopefully the names are sufficient to suggest what they do exactly. The settings are under User Settings so there is no Loopback processing required (if my understanding is correct). GP Modelling for the user and specific computer says that the GPOs will/should be applied, however on the client, gpresult doesn't even appear to see the GPOs under either "Applied" or "Not Applied": USER SETTINGS -------------- CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local Last time Group Policy was applied: 25/06/2012 at 11:07:13 AM Group Policy was applied from: svr-addc-01.natorg.local Group Policy slow link threshold: 500 kbps Applied Group Policy Objects ----------------------------- LAPTOPS - Power Settings WSUS - Set Server Address OUTLOOK - Auto Archive SECURITY - Lock Screen After Idle Default Domain Policy DESKTOP - Regional Settings NETWORK - Proxy Configuration NETWORK - IE General Config OFFICE - Trusted Locations OFFICE - Increase Privacy OUTLOOK - Disable Junk Filter DESKTOP - Disable Windows Error Reporting DESKTOP - Hide Language Bar NETWORK - Disable Skype DESKTOP - Disable Thumbs.db Creation WSUS - Set Server Address The following GPOs were not applied because they were filtered out ------------------------------------------------------------------- Local Group Policy Filtering: Not Applied (Empty) NETWORK - Google Chrome Configuration Filtering: Not Applied (Empty) SYSTEM - Event Log Configuration Filtering: Not Applied (Empty) SECURITY - Local Administrator Password Filtering: Not Applied (Empty) NETWORK - Disable Windows Messenger Filtering: Not Applied (Empty) SECURITY - Audit Policy Filtering: Not Applied (Empty) WSUS - Automatic Install Filtering: Not Applied (Empty) NETWORK - Firewall Configuration Filtering: Not Applied (Empty) DESKTOP - Enable Offline Files Filtering: Not Applied (Empty) I haven't altered permissions on the GPO's at all, no WMI filtering... As I said, GP Modelling says that they should be applied. GPResult on the client correctly identifies itself as being the correct OU (CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local) There are 2 x 2008R2 and a 2003 DC, domain is 2003 level, client is Windows XP SP3. Can anyone suggest why these GP Objects would be "invisible" to the client?

  • Adding network share as the system account breaks Win7 backup to network

    - by ChrisBenn
    (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

  • EC2 Configuration

    - by user123683
    I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

  • How to wake from screensaver directly to the login screen in Ubuntu

    - by torbengb
    (a.k.a. How to switch users without entering password, part II) (see part I) I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). Part of this was answered in my earlier question which helped me get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?

  • MS SQL to MySQL using MySQL Migration Toolkit: permission issue

    - by Zeno
    I have a MS SQL imported into SQL Server 2008 from a .bak and I set it to Mixed mode. I have a SQL user (called "test") that can correctly access the database using SQL Server. I need to convert this to a MySQL database, so I got the MySQL Migration Toolkit. I pick "MS SQL Server" and then it asks for the hostname/username/password/database. I'm not 100% sure on these, but I used "localhost" (running on same computer), left the port as is (1433) and the username/password ("test") for the SQL Server. And I used the database name for the SQL Server database I'm looking to import. I clicked next, enter my MySQL database details and then attempt to run it and I get this error: Connecting to source database and retrieve schemata names. Initializing JDBC driver ...
