Accidently overwrote system.dbf - What now?

- by Filip Ekberg

I accidentally overwrote system.dbf in /usr/lib/oracle/xe/oradata/XE/system.dbf Well I did not actually do it accidentally, however I overwrote it because of other failures in the database. And when I try running the following: SQL> shutdown ORA-01109: database not open Database dismounted. ORACLE instance shut down. SQL> startup ORACLE instance started. Total System Global Area 289406976 bytes Fixed Size 1258488 bytes Variable Size 92277768 bytes Database Buffers 192937984 bytes Redo Buffers 2932736 bytes Database mounted. ORA-01589: must use RESETLOGS or NORESETLOGS option for database open Now I want to try to Recover the database because starting it in mounted or standard surely doesn't work. SQL> recover database using backup controlfile; ORA-00283: recovery session canceled due to errors ORA-01110: data file 1: '/usr/lib/oracle/xe/oradata/XE/system.dbf' ORA-01122: database file 1 failed verification check ORA-01110: data file 1: '/usr/lib/oracle/xe/oradata/XE/system.dbf' ORA-01206: file is not part of this database - wrong database id How do I solve this? Is it even possible? My "real" problem was that I ran the /etc/init.d/oracle-xe configure and it overwrote my old configuration and probably removed passwords and such so my tables were gone, however I found the mytablespace.dbf so I hope that it is possible to recover? Please shed some light on this.

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?

Setting up Apache 2.2 + FastCGI + SuExec + PHP-FPM on Centos 6

- by mr1031011

I'm trying to follow this very detailed instruction here, I simply changed from www-data user to apache user, and is using /var/www/hosts/sitename/public_html instead of /home/user/public_html However, I spent the whole day trying to figure out why the php file content is displayed without being parsed correctly. I just cant's seem to figure this out. Below is my current config: /etc/httpd/conf.d/fastcgi.conf User apache Group apache LoadModule fastcgi_module modules/mod_fastcgi.so # dir for IPC socket files FastCgiIpcDir /var/run/mod_fastcgi # wrap all fastcgi script calls in suexec FastCgiWrapper On # global FastCgiConfig can be overridden by FastCgiServer options in vhost config FastCgiConfig -idle-timeout 20 -maxClassProcesses 1 # sample PHP config # see /usr/share/doc/mod_fastcgi-2.4.6 for php-wrapper script # don't forget to disable mod_php in /etc/httpd/conf.d/php.conf! # # to enable privilege separation, add a "SuexecUserGroup" directive # and chown the php-wrapper script and parent directory accordingly # see also http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/ # FastCgiServer /var/www/www-data/php5-fcgi #AddType application/x-httpd-php .php AddHandler php-fcgi .php Action php-fcgi /fcgi-bin/php5-fcgi Alias /fcgi-bin/ /var/www/www-data/ #FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /tmp/php5-fpm.sock -pass-header Authorization #DirectoryIndex index.php # <Location /fcgi-bin/> # Order Deny,Allow # Deny from All # Allow from env=REDIRECT_STATUS SetHandler fcgid-script Options +ExecCGI </Location> /etc/httpd/conf.d/vhost.conf <VirtualHost> DirectoryIndex index.php index.html index.shtml index.cgi SuexecUserGroup www.mysite.com mygroup Alias /fcgi-bin/ /var/www/www-data/www.mysite.com/ DocumentRoot /var/www/hosts/mysite.com/w/w/w/www/ <Directory /var/www/hosts/mysite.com/w/w/w/www/> Options -Indexes FollowSymLinks AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> PS: 1. Also, with PHP5.5, do I even need FPM or is it already included? 2. I'm using mod_fastcgi, not sure if this is the problem and it I should switch to mod_fcgid? There seems to be conflicting records on the internet considering which one is better. I have many virtual hosts running on the machine and hope to be able to provide each user with their own opcache

Nagios Apache Config with PHP-FPM downloading cgi files

- by tubaguy50035

I'm trying to setup Nagios 3 under Apache 2.4 with PHP-FPM. I've run into a couple problems I could use help with. The PHP side of things seems to be working, I can see the home page and the sidebar. But all of the CGI files are downloading instead of executing, and when I try to click on "Read What's New In Nagios Core 3", I get an error /nagios3/docs/whatsnew.html was not found on this server.

ASA DHCP Relay configuration..

- by Jeff

I have locations in different cities, connected using 2 Cisco ASA devices. my main location, corporate, use the IP 192.168.1.x The second location, remote store, use the IP 192.168.3.x I have a DHCP server (192.168.1.254) at my corporate location. I have created a scope for the 192.168.1.x which works fine for the corporate location. I created a scope for the remote location (192.168.3.x) on my DHCP server and tried to configure the remote ASA DCHP Relay, on the remote ASA: I disabled the DHCP Server on the inside. I enabled DHCP Relay on the inside, with set route set at yes. I set the Global DHCP Relay Servers, specify up to four servers to which DHCP requests would be relayed. I added my DHCP, 192.168.1.254 I flashed these settings to the ASA and gave it a try, didn't do anything. am i missing something - forgetting something. not really sure what im doing wrong. DHCP Settings on remote ASA: dhcp-client update dns server both dhcpd dns 192.168.1.254 dhcpd ping_timeout 750 dhcpd domain JEWELS.LOCAL dhcpd auto_config outside dhcpd update dns both ! dhcpd address 192.168.3.2-192.168.3.33 inside ! dhcprelay server 192.168.1.254 outside dhcprelay enable inside dhcprelay setroute inside on my local ASA: i have two ACLs for UDP ports 67 and 68 permitting any inbound traffic from the remote locations IP ... dhcprelay timeout 120

Replace text with spaces in MySQL

- by javipas

I'm trying to do a global replace of search in my database, which has a lot of articles with a double carriage return because of this code: I'd like to replace this in my WordPress blog so instead of that appears... nothing, and so I can delete the CR. I've tried this on my database UPDATE wp_posts set post_content = replace (post_content,' ',''); but didn't work. Why? Do I have to add special thinks to consider the space between the and the? Mmm. Good points, both Jon Angliss and Wim. Jon, as you could have guessed, the database shows no entries with that text string. So there's something going on inside the post_content field. Wim, the famous was replaced previously, but there are still hundreds of posts that for some reason have something different between the p and the /p tags. I've done a search of one of the posts with this error: mysql> select * from wp_posts where post_title like '%3DVisionLive%'; And looking in the wp_content field, this is a little piece of the post: Phil Eisler, responsable de la divisi?n 3D Vision.? ? Este portal ser? por tanto No spanish tilde (accent) shown on the terminal, and instead of an space there's a quotation mark between the p and the /p tags. I've tried to replace ?, but again, no results. There's some character (or several) there, but I don't know how to discover that. Maybe it's the character set of my terminal, but I've accessed the database from phpmyadmin and in that case there's a space character between the p and the /p. Weird.

Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

- by e-t172

Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

nginx php-fpm empty site

- by Katafalkas

I am writing this as I was stuck trying to fix it whole night. We have recently migrated to a new server. Before migration we have been running our site on nginx + cgi (script). After migration we decided to try apache + mod_php. It was rather terrible, and I would like to migrate back to nginx, but this time I want it with php-fpm (as people say its a cool) So I did follow a number of guides and I think i done everything correctly. As well as that I have our old config files for "server" section, which i reviewed and places into new config. So I ended up having an empty site when I enter our URL. (By empty I mean blank page, no letter, errors or anything at all.) In the access log there are some weird errors like: 123.242.148.54 - - [22/Mar/2012:06:08:11 +0200] "-" 400 0 "-" "-" My guess is that php-fpm is not working, but not sure how to confirm it. Maybe some1 could give some help ? Would much appreciate. my nginx config: user nginx; worker_processes 12; error_log /var/log/nginx/error.log; #error_log /var/log/nginx/error.log notice; #error_log /var/log/nginx/error.log info; pid /var/run/nginx.pid; events { worker_connections 4096; } http { include /etc/nginx/mime.types; #default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; fastcgi_buffer_size 256k; fastcgi_buffers 4 256k; server { listen 80; server_name www.example.com; access_log /var/log/nginx/example.access.log; error_log /var/log/nginx/error.log; root /home/www/example; index index.php; client_max_body_size 50M; #error_page 404 /404.html; # phpMyAdmin location /phpmyadmin { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; try_files $uri $uri/ /index.php; } location ~ ^/phpmyadmin/.*\.php$ { root /usr/share/; error_log /var/log/nginx/phpmyadmin.log; include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } # Munin location /monitoring { root /var/www/; auth_basic "Restricted"; auth_basic_user_file /etc/nginx/conf.d/monitoring_users; error_log /var/log/nginx/monitoring.log; index index.html; } # The site location / { try_files $uri $uri/ /index.php/?$uri&$args; } # PHP interpreter location ~ \.php { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } }

Cant connect to MySQL server from Java application

- by RN

This is on VPS\Centos server. The MySQL server is pre configured. I am running the Java application on Tomcat My Java web application is not able to connect to the MySQL server. I get an error - "Caused by: java.net.ConnectException: Connection refused" I suspect this to be a configuration problem rather than a coding problem- hence I have posted this on ServerFault And yes, The same web-app is able to connect to MySQL on a different linux box This is the URL that I provided to my Java application (note- it assumes default port) url = "jdbc:mysql://localhost/pickupgames" My first suspicion was that I am running on a non-default port So I tried to find the port where mySQL server is running I tried every trick mentioned in http://serverfault.com/questions/116100/how-to-check-what-port-mysql-is-running-on But no luck ! SHOW GLOBAL VARIABLES LIKE 'PORT'; This shows port 0 netstat -tlnp doesn't show mysql at all /etc/my.cnf It has no port entry telnet localhost 3306 Doesn't connect And in case you are wondering if mysql server is running at all or not It is And I know for sure, because I have been able to login using the mysql command Also # ps -ef|grep 'mysql' root 31839 27662 0 00:49 pts/3 00:00:00 grep mysql root 32452 1 0 Apr02 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe --skip-grant-tables --skip-networking mysql 32504 32452 0 Apr02 ? 00:00:06 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock --skip-grant-tables --skip-networking Please note the --skip-networking parameter Does this have something to do with the issue ? Any explanation why I cant connect to mysql server on port 3306 by telnet? Or why it docent show up under netstat? Any suggestion on whet I should try next ?

How often is CRL refreshed, and how to force it to be?

- by lockstock

I have a web service running under IIS 7 that requires an X509 client certificate. I know that the server that it rus on needs access to DigiCert.com in order to be able to get the CRL (Certificate Revocation List). There is a need to change our proxy so I am attempting to investigate the impact of doing so. I have removed the global proxy settings using the command netsh winhttp proxy refesh, and also deleted the CRL cache using the command certutil -URLcache CRL delete. However, after doing this, all calls to the web service still succeed. This suggests to me that I am missing something here. So; If the CRL cache is cleared and the server has no way of refreshing the CRL, why do web service requets not return http 403?. I have been unable to find adequate information from googling nor from my colleagues. The reason I want it to fail is that I will not be confident that the new proxy settings work until I can see it broken first, if that makes sense. I would also like to be able to force the CRL to be refeshed in order to ensure that the new proxy settings work

sorry, the maximum allowed clients from your host (10) are already connected" FTP error

- by Sejanus

Hello, I keep getting the "sorry, the maximum allowed clients from your host (10) are already connected" error whenever I try to transfer a large number of files. At first I thought it's a filezilla bug, however I get the same error basically with every FTP client I've tried, including Total Commander under Wine. I do not get that error using Windows. I did try to limit maximum allowed connections for Filezilla, both in server settings and in global settings, it didnt change anything. I did try to switch between passive and active modes (not sure if it's related at all, just last desperate attempt), and it didnt change anything either. When I try to use native ftp client (not sure how is it called, the one in Places - Connect to a server) I get abstract "connection refused" error every time I transfer large number of files. Connection is refused for separate particular files, if I click "Ignore" each time the rest of files are transfered perfectly well, so I assume it's the very same error. Anything I could do? This really drives me mad, transfering large numbers of files is a part of my everyday job... P.S. and this happens with many different FTP servers. Also I dont get this error in Windows. So I assume it's not a server problem. P.P.S. I am aware of similar question here, the answer provided just didn't solve it to me.

Samba 3.5 Shadow Copy for Windows 7

Have I pushed the limits of my current VPS or is there room for optimization?

- by JRameau

I am currently on a mediatemple DV server (basic) 512mb dedicated ram, this is a CentOS based VPS with Plesk and Virtuozzo. My experience with it from day 1 has been bad and I only could sooth my server issues with several caching "Band-aids," but my sites are not as small as they were a year ago either so the issues have worsen. I have 3 Drupal installs running on separate (plesk) domains, 1 of those drupal installs is a multisite, that consists of 5-6 sites 2 of those sites are bringing in actual traffic. Those caching "Band-aids" I mentioned are APC, which seemed to help alot initially, and Drupal's Boost, which is considered a poorman's Varnish, it makes all my pages static for anonymous users. Last 30day combined estimate on Google Ananlytics: 90k visitors 260k pageviews. Issue: alot of downtime, I am continually checking if my sites are up, and lately I have been finding it down more than 3 times daily. Restarting Apache will bring it back up, for some time. I have google search every error message and looked up ways to optimize my DV server, and I am beyond stump what is my next move.

nameserver spoiling avahi multicast name resolution of .local domain

- by Doug Coburn

After trying to ping a machine on my local network, I noticed that I was trying hit address 66.152.109.24. This is an external public address. Resolution should have occurred via avahi mDNS. I ran dig to see how the name resolution worked and my quest/centurylink name server was retuning results for my .local domain queries!

"cannot receive new filesystem stream: invalid backup stream" error when unpacking flash archive on solaris 10

- by Bovril

I've searched around but i'm having no luck with some peculiar behavior with a flash archive. I'm using HP Server Automation 9.14 to deploy the OS. I'm creating a Solaris 10 flash archive to create a snapshot default build in our environment. I create the flash archive with # flar create -c -S -n g8-solaris10-u10 g8-solaris10-u10.flar It seems to create the file without any problems (exit status 0). When deploying to a new system (same hardware), it extracts to a point and then bails. The last error in the log I can see is Extracted 2047.00 MB ( 82% of 2488.98 MB archive) ERROR: Could not read file (172.27.118.100:/media/opsware/sunos/flar/g8-solaris10-u10.flar ERROR: Errors occurred during the extraction of flash archive. The file /tmp/flash_errors contains the list of errors encountered ERROR: Could not extract Flash archive ERROR: Flash installation failed The error log contained the following message cannot receive new filesystem stream: invalid backup stream A previous version of this flash archive (1.8gb) worked ok, so I suspect size may be a factor. The source system (the one the flash archive is an image of) is an HP BL460C GEN8 some more info below. OS version Info # uname -a SunOS testhostname 5.10 Generic_147441-01 i86pc i386 i86pc # who -r . run-level 3 Oct 15 08:15 3 0 S disks # echo | format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t0d0 <DEFAULT cyl 17841 alt 2 hd 255 sec 63> /pci@0,0/pci8086,3c06@2,2/pci103c,3355@0/sd@0,0 Specify disk (enter its number): Specify disk (enter its number): zpools # zpool list NAME SIZE ALLOC FREE CAP HEALTH ALTROOT rpool 136G 24.6G 111G 18% ONLINE - Zones # zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / native shared The file size of 2047 seems suspiciously close to 2048, which is concerning.

Can't add service account to domain group during SQL cluster install

- by Sam

I'm installing a 2008 instance on a Server 2003 machine which is already running SQL 2005. I need to set up domain groups for the security setup step: http://msdn.microsoft.com/en-us/library/ms179530.aspx On Windows Server 2003, specify domain groups for SQL Server services. All resource permissions are controlled by domain-level groups that include SQL Server service accounts as group members. Much more info on this here: http://support.microsoft.com/kb/910708 I've had problems with being able to add the windows service accounts to the groups at install time. The security admins had to make my account a domain admin - which they were hesitant to do. The account under which SQL Server Setup is running must have permissions to add accounts to the domain groups. Is there a specific security setting which would allow my account to add accounts to a group? UPDATE: I'm looking for specific instructions. I have a global group called domain\servicegroup - what do I tell the security folks to do. I'd love to figure it out myself, but I don't have access to this stuff.

Samba between Ubuntu server 10.10 and Windows Vista, Windows 7

- by chepukha

Hi all, I have a linux box running Linux server ubuntu 10.10. I have installed Samba on this linux box and want to share files with my laptops which run Windows Vista home and Windows 7 home. I have been struggling with the setup for almost a month but couldn't get it right. If I try to access share folder from Windows Vista, I get message "Windows cannot access \\server_ip_address". Error code: 0x80070035. The network path was not found. If I access from Windows 7, then after entering password to login I can see the list of share folders on Linux box. But if I click on a share folder, I get the same error message as above. Tail /var/log/samba/log.windows7-pc I got the following message: [2011/03/16 00:17:41.427238, 0] smbd/service.c:988(make_connection_snum) canonicalize_connect_path failed for service sharemedia, path /root/sharemedia Here is my setting in smb.conf [global] share modes = yes netbios name = Samba workgroup = WORKGROUP wins support = yes encrypt passwords = true [sharemedia] comment = Tesing sharing using Samba path=/root/sharemedia/ public = yes valid users = samba_usr_name ; make sure all files are sensible permissions create mask = 0660 force create mask = 0660 directory mask = 2770 force directory mask = 2770 directory security mask = 0000 ; Normal share parameters read only = no browseable = yes writable = yes guest ok = no

Mac OS X Client With Static DHCP Assignment Requests Wrong IP via Option 50

- by Starchy

I have a number of Mac (and a few Linux) laptops getting DHCP from a Force10 layer 3 switch, the only DHCP server on the subnet. There's a global dynamic pool, and for each full-time employee's laptop I have a single IP static pool set by MAC address. One and only one of the clients, running OS X 10.7.5, consistently fails to get a static assignment. The MAC address in the static pool definition has been carefully re-checked. Running tcpdump on a mirrored port when the laptop connects, I see that it is specifically requesting 10.100.0.252 (a dynamic address): 11:32:10.108280 IP (tos 0x0, ttl 255, id 28293, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > broadcasthost.bootps: [udp sum ok] BOOTP/DHCP, Request from 3c:07:54:xx:xx:xx (oui Unknown), length 300, xid 0x1399da89, Flags [none] (0x0000) Client-Ethernet-Address 3c:07:54:xx:xx:xx (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Request Parameter-Request Option 55, length 9: Subnet-Mask, Default-Gateway, Domain-Name-Server, Domain-Name Option 119, LDAP, Option 252, Netbios-Name-Server Netbios-Node MSZ Option 57, length 2: 1500 Client-ID Option 61, length 7: ether 3c:07:54:xx:xx:xx Requested-IP Option 50, length 4: 10.100.0.252 Lease-Time Option 51, length 4: 7776000 Hostname Option 12, length 10: "host-name" END Option 255, length 0 PAD Option 0, length 0, occurs 8 I haven't been able to find any extra system prefs or unusual software on the laptop. Disabling the interface and rebooting or temporarily setting the IP manually both fail to make any difference. Any suggestions appreciated.

Problem adding second domain controller to SBS 2008

- by Quango

Have an SBS 2008 server in one location, and want to add a backup domain controller at a different site. The two sites are linked by a VPN. New server is running Server 2008 R2, fully patched. At present it is a member server and the DNS is pointing at the SBS DNS. When I try running DCPROMO to connect the server, the wizard runs fine up to the point where the wizard is 'configuring Active Directory Domain Services' and 'examining forest': "The operation failed because: The wizard could not read operational attributes from the remote Active Directory Domain Controller SERVER.DOMAIN.LOCAL using LDAP. "The specified server cannot perform the requested operation." This error can occur if you have not been granted necessary permissions to read data in the directory. For more information, please see article 936241 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkId=88420)." I was logged on as domain administrator. Interestingly the link is invalid and the KB article does not exist..! Settings: Configure this server as an additional Active Directory domain controller for the domain "[domain]". Site: [site] Additional Options: Read-only domain controller: "No" Global catalog: Yes DNS Server: Yes Update DNS Delegation: No Source domain controller: any writable domain controller Database folder: C:\Windows\NTDS Log file folder: C:\Windows\NTDS SYSVOL folder: C:\Windows\SYSVOL The DNS Server service will be configured on this computer. This computer will be configured to use this DNS server as its preferred DNS server.

MOSS2007 tries to use ActiveDirectory when I have configured an alternative membership provider

- by glenatron

I've got a MOSS site that I am trying to configure using Forms authentication and absolutely any kind of membership provider whatsoever. Thus far ActiveDirectory has proved obstructively difficult so I've just whipped up a simple stub membership provider and put it in the GAC. It's a very basic and simple provider but it works fine with an ASP.Net site, I just can't make it work with Sharepoint. On Sharepoint I get the following error when I look for StubProvider:Bob ( or anything else for that matter) from the "Policy For Web Application" people picker: Error in searching user 'StubProvider:bob' : System.ComponentModel.Win32Exception: Unable to contact the global catalog server at Microsoft.SharePoint.Utilities.SPActiveDirectoryDomain.GetDirectorySearcher() at Microsoft.SharePoint.WebControls.PeopleEditor.SearchFromGC(SPActiveDirectoryDomain domain, String strFilter, String[] rgstrProp, Int32 nTimeout, Int32 nSizeLimit, SPUserCollection spUsers, ArrayList& rgResults) at Microsoft.SharePoint.Utilities.SPUserUtility.SearchAgainstAD(String input, SPActiveDirectoryDomain domainController, SPPrincipalType scopes, SPUserCollection usersContainer, Int32 maxCount, String customQuery, TimeSpan searchTimeout, Boolean& reachMaxCount) at Microsoft.SharePoint.Utilities.SPActiveDirectoryPrincipalResolver.SearchPrincipals(String input, SPPrincipalType scopes, SPPrincipalSource sources, SPUserCollection usersContainer, Int32 maxCount, Boolean& reachMaxCount) at Microsoft.SharePoint.Utilities.SPUtility.SearchPrincipalFromResolvers(List`1 resolvers, String input, SPPrincipalType scopes, SPPrincipalSource sources, SPUserCollection usersContainer, Int32 maxCount, Boolean& reachMaxCount, Dictionary`2 usersDict). The Provider is named as Authentication Provider for the Site Collection in question. As far as I can tell this is because Sharepoint is still trying to access ActiveDirectory rather than talking to the provider I'm asking it to use. My Sharepoint Central Administration section includes this: <membership> <providers> <add name="StubProvider" type="StubMembershipProvider.Provider, StubMembershipProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5bd7e2498c3e1a03" /> </providers> </membership> And also: <PeoplePickerWildcards> <clear /> <add key="StubProvider" value="%" /> </PeoplePickerWildcards> Is there a clear reason why this would not be accessible from the PeoplePicker or why it is still trying to use ActiveDirectory? I've made sure I reset IIS and even restarted the server to see if either of those helped but they made no difference.

Calendar sharing between unrelated Domains

- by vlannoob

I have a 'request' from one of the 'big guys' that has me scratching my head a bit. He is one of our Executives that also is a board member of several other organistations, so he floats around between 4 different unrelated companies, each with their own domains, Exchange setup etc. He has domain accounts in each organisation. He has an iPad with multiple Exchange accounts so he can see all his calendars which works Ok for him - Apple calendaring bugs/flaws aside. What he wants is the ability for 'reception staff' at each organisation to 'see' all his calendars as they are booking things for him in their respective organisations calendars without it conflicting with bookings made in his calendars by other organisations......you with me?? So for example: Company A books a meeting into his Comapny A calendar at 9am Monday and Company B books him a meeting in his Company B Calendar at 9:15am Monday on the other side of town and of course Company C has him booked in all day Monday on their Company C calendar. He gets all those on his iPad but he would like either a 'global' calendar all can see and book into or the ability for receptionists at Company's A,B and C to see all the Calendars to avoid these kind of conflicts. I told him to 'go away' straight off the bat, I don't control anything to do with the other companies or know their infrastructure. And quite frankly I don't want any part of it...but he's whining and he's high enough up the food chain that I can't ignore him forever. I'm open to suggestions. Is there any third party software/services that can facilitiate this kind of setup? I really don't want to be creating users in my AD structure to people not ion our organisation so they can get access to his calendar and I am sure there sysadmins feel the same. As usual - any advice is greatly appreciated ;)

Samba server NETBIOS name not resolving, WINS support not working

- by Eric

When I try to connect to my CentOS 6.2 x86_64 server's samba shares using address \\REPO (NETBIOS name of REPO), it times out and shows an error; if I do so directly via IP, it works fine. Furthermore, my server does not work correctly as a WINS server despite my samba settings being correct for it (see below for details). If I stop the iptables service, things work properly. I'm using this page as a reference for which ports to use: http://www.samba.org/samba/docs/server_security.html Specifically: UDP/137 - used by nmbd UDP/138 - used by nmbd TCP/139 - used by smbd TCP/445 - used by smbd I really really really want to keep the secure iptables design I have below but just fix this particular problem.

Delay NTP Initialisation, Cisco 877W, IOS 12.4(24)T1

- by Mike Insch

I have a Cisco 877W which I'm using for my home ADSL connection (and as a refresher in Cisco IOS). I've got a working config in-place with my PPPoA connection coming online correctly, and VLANs and other settings configured as I want them, but I can't crack the NTP configuration. For NTP, I have the following defined ntp server 0.uk.pool.ntp.org source Dialer0 ntp server 1.uk.pool.ntp.org source Dialer0 ntp server 2.uk.pool.ntp.org source Dialer0 ntp server 3.uk.pool.ntp.org source Dialer0 This setup works fine when issued in Global Configuration Mode when the Dialer0 interface (ATM0.1) is up. The configuration fails at startup though: Translating "1.uk.pool.ntp.org"...domain server (208.67.222.222) (208.67.220.220) ntp server 1.uk.pool.ntp.org source Dialer0 ^ % Invalid input detected at "^" marker. This is repeated for the other servers defined. Obviously the DNS lookup for the server(s) fails because the DNS servers cannot be accessed because the external interface is not yet online. Is there a way to delay the NTP configuration until afte the Dialer0 interface is fully initialised? Can the NTP commands be triggered by the Line Protocol on the Dialer0 interface transitioning to the up state? Alternatively, can the NTP commands be delayed for 5 minutes after the router has finished initialising? Any advice, or pointers to useful documentation or examples gratefully received ...
