  • How can I make the Windows 7 taskbar behave like a cross between the old Quick Launch and new Superbar?

    - by frumious
    I really like the taskbar in Windows 7, I think combining buttons to launch apps and the icons that show your running apps is groovy. However, because I like having as much space as possible, I've got small icons enabled and shrunk the bar down to one row. I've also told it not to group the running apps unless there's no space left (to save me having to work harder to find the particular window I want), which also means that they have captions, and are thus quite wide. The (admittedly small) problem this gives me is that I can pin all my favourite apps to the bar, which looks much like the old Quick Launch bar, but when I launch them the running apps because much wider, and the unlaunched apps get lost amongst them. I can manually change the order to fix this, but next time I'll launch a different app and I'll be back to square one. What I'd prefer is for small unlaunched icons to be kept on the left, and wider running apps to move over to the right, which for me would be the best of both worlds. Is there any way I can organise that? I'm aware that one can use the traditional quick launch bar in Windows 7, but that's not what I'm after; I generally prefer the Windows 7 way.

  • CentOS tftp server is broken

    - by Mike Pennington
    I'm trying to run tftpd from xinetd on CentOS 6; however, I can only tftp from localhost. I have a file in /opt/tftpboot/fw.test.conf that I can retrieve if I tftp to localhost: [mpenning@localhost ~]$ tftp localhost tftp> get fw.test.conf tftp> quit [mpenning@localhost ~]$ ls fw.test.conf [mpenning@localhost ~]$ However, I cannot receive this file if I tftp to eth1 on this server (the address on eth1 is 172.16.1.4).

  • RPM issues after signing JDK 1.6 64-bit

    - by organicveggie
    I'm trying to sign the Java JDK 1.6u21 64-bit RPM on CentOS 5.5 for use with Spacewalk and I'm running into problems.

  • SQL Server 2008 Cluster Installation - First network name always fails

    - by boflynn
    I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

  • How to subnet hosted VMs

    - by bwizzy
    I have a network of VMs each having a LAN IP address and a public IP address. They each have a 1:1 NAT map for public access via the public IP for HTTP, SSH etc. I'm trying to figure out a way to restrict the LAN IPs from talking to each other, but there are some cases where a group of LAN IPs will need to communicate. I'm using pfSense as a firewall / router on a 192.168.0.0/24 configuration. It seems like I could assign each VM it's own subnet and add a static route to the firewall for that VM to get back to the firewall for internet access / other fw rules. Is that right? I assigned 1 VM with: address 192.168.1.2 netmask 255.255.255.254 gateway 192.168.1.1 Then added a static route on the FW's LAN interface using 192.168.1.0/30 as the destination network and 192.168.1.1 as the gateway. Nothing appears to be working, anyone have any ideas? Please be aware I'm not that familiar with subnets. Thanks!

  • HAproxy with MySQL Master-Master Replication incredibly slow

    - by Yayap
    I have two MySQL servers in multi-master mode, with an HAproxy machine for simple load balancing/redundancy. When I am connected to one of the servers directly and try to update about 100,000 entries, it is completed including replication in about half a minute. When connecting through the proxy it takes usually over three whole minutes. Is it normal to have that type of latency? Is something amiss with my proxy configuration (included below)? This is getting really frustrating as I assumed the proxy would do some sort of load balancing, or at least have little to no overhead. #--------------------------------------------------------------------- # Example configuration for a possible web application.

  • Libraries merged folder views

    - by Stigma
    So I pretty much love the Windows 7 Libraries feature, and saw one use for them that I thought would be perfect, but I can't seem to manage it. Basically, a merged view of different folder structures. Suppose I make a new generic library and add three locations to it: C:\Test\, D:\Test\ and D:\temp\Test\. Now, these may look somewhat okay as long as there are no duplicates in these folders. (It wants to group them based on the included directory, which one can work around by looking on google - I don't have the precise trick on hand I am afraid.) But when you get collisions and, say, two of those directories have a Sub directory in them, stuff becomes unusable (assuming Arrange by: Folder view). You'll have multiple folders listed named Sub, which is pretty useless when looking for data. I want folders to get 'merged', which ought to be possible somehow since it can create these merged views based on artist, album etc in other views. So all subdirectories that are double (and recursively checking for doubles inside those, etc) ought to be merged for as far the View is concerned. If files have a collision, I don't really care what happens - hide one, show both, filter out duplicates, whatever. (Although an option would be nice...) Anyhow, is there anyone who knows how to get such a 'merged folder structure' functionality for Libraries? It would be really useful for me.

  • Fixed and dynamic IPs in ISC DHPD lead to double lease

    - by GorillaPatch
    I would like to have a small dynamic adress part and the most clients are assigned a fixed IP adress. My dhcpd.conf looks like this: use-host-decl-names on; authoritative; allow client-updates; ddns-updates on; # Einstellungen fuer DHCP leases default-lease-time 3600; max-lease-time 86400; lease-file-name "/var/lib/dhcpd/dhcpd.leases"; subnet 192.168.11.0 netmask 255.255.255.0 { ddns-updates on; pool { # IP range which will be assigned statically range 192.168.11.1 192.168.11.240; deny all clients; } pool { # small dynamic range range 192.168.11.241 192.168.11.254; # used for temporary devices } } group { host pc1 { hardware ethernet xx:xx:xx:xx:xx:xx; fixed-address 192.168.11.11; } } The motivation for the pool declaration with deny all hosts comes from the ISC DHCPD homepage http://www.isc.org/files/auth.html This will allow hosts to be first added to the network, where they will receive a temporary IP from the 241-254 adress range and then later write an explicit host declaration. Upon next connect it will receive the right configuration. The problem is that I am getting error messages that 192.168.11.13 has a dynamic and a static lease. I am a bit confused as I expected the pool declaration with deny all clients would not count as dynamic. Dynamic and static leases present for 192.168.11.13. Remove host declaration pc1 or remove 192.168.11.13 from the dynamic address pool for 192.168.11.0/24 Is there a way to have the DHCP server send an DHCPNA to clients if they have a host statement and retain this dynamic range?

  • Is there the equivalent of cloud computing for modems?

    - by morpheous
    I asked this question on SF, and someone recommended that I ask it here - (I don't think I have enough points to move a question from SF to SO - and in any case, I don't know how to do it - so here is the question again): I am interested in the concept of PAAS (platform as a service). However, all talk about SAAS/PAAS seems to focus on only the computer itself - not its peripherals. Is it possible to 'outsource' modems as a resource - so that an app running remotely can pump data to a modem in the cloud? As a bit of background to the question, a group of us are thinking of starting a company that offers similar services to companies like twilio etc - but I want to 'outsource' both the computing hardware (thats PAAS - the easy bit) and the modems (thats what I cant seem to find any info on). Does anyone know if modems can be bundled as part of a PAAS service? - alternatively, is there a way that an application running on one computer can communicate (i.e. pump data) to a remote modem residing on another machine?. I assume I can come up with some protocol over UDP or TCP - but there is no point reinventing the wheel - if such a protocol like that already exists (or if it some open source software allows one to do this). Any suggestions on how to solve this problem?

  • fcgiwrap listening to a unix socket file: how to change file permissions

    - by user36520
    I have a web server (nginx) and a CGI application (gitweb) that is ran with fcgiwrap to enable Fast CGI access to it. I want the Fast CGI protocol to take place over a unix socket file. To start the fcgiwrap daemon, I run: setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" (this is a daemontools daemon) The problem is that my web server runs as the user www-data and not the user git. And fcgiwrap creates the socket fastcgi.sock with user git, group git and read only fort the non owner. Thus, nginc with the user www-data can't access the socket. Apparently, fcgiwrap is not able to select permissions of unix socket files. And this is quite annoying. Moreover, if I manage to have the socket file exists before I run fcgiwrap (which is quite difficult given I did not find any shell command to create a socket file), it quits with the following error: Failed to bind: Address already in use The only solution I found is to start the server the following way: rm -f fastcgi.sock # Ensure that the socket doesn't already exists (sleep 5; chgrp www-data fastcgi.sock; chmod g+w fastcgi.sock) & exec setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" Which is far from the most elegant solution. Can you think of anything better ? Thanks

  • "Server Unavailable" and removed permissions on .NET sites after Windows Update

    - by tags2k
    Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.

I had to remove the cache directory as I was testing something. Remade it, re-set permissions and found that eAccelerator was no longer creating cache files within the folder. I thought it might be down to ownership rights on the folder so chown'd it apache.apache and this made no difference. I recreated the directory in /var/cache instead and editted php.ini to point to the new cache dir location, chmod'd, chown'd etc. and still eAccelerator is not creating any of the cache files in the directory (just empty). Could someone suggest what I might be doing incorrectly here. I've read through numerous pages to try and troubleshoot the issue to no avail. Any help appreciated.

I found this one-liner, but it requires the a Unix/Linux host: ssh -q -o "BatchMode=yes" user@host "echo 2>&1" && echo "UP" || echo "DOWN" Telnet'ing to port 22 works, but that's not really scriptable. I have also played around with Plink, but I haven't found a way to get the functionality of the one-liner above. Does anyone know Plink enough to make this work? Are there any other windows based tools that would work? Please note that the SSH servers in question are behind a corporate firewall and are NOT internet accessible. Arrrg. Figured it out: C:\>plink -batch -v user@host Looking up host "host" Connecting to 10.10.10.10 port 22 We claim version: SSH-2.0-PuTTY_Release_0.62 Server version: SSH-2.0-OpenSSH_4.7p1-hpn12v17_q1.217 Using SSH protocol version 2 Server supports delayed compression; will try this later Doing Diffie-Hellman group exchange Doing Diffie-Hellman key exchange with hash SHA-256 Host key fingerprint is: ssh-rsa 1024 aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa Initialised AES-256 SDCTR client->server encryption Initialised HMAC-SHA1 client->server MAC algorithm Initialised AES-256 SDCTR server->client encryption Initialised HMAC-SHA1 server->client MAC algorithm Using username "user".

  • HAProxy is caching the forwarding?

    - by shadow_of__soul
    i'm trying to set up a server structure for an application i'm building in Node.js with socket.io. My setup is: HAProxy frontend forward to -> apache2 as default backend (or nginx, is apache in this local test) -> node.js app if the url has socket.io in the request AND a domain name i have something like: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 user haproxy group haproxy daemon defaults log global mode http maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 frontend all 0.0.0.0:80 timeout client 5000 default_backend www_backend acl is_soio url_dom(host) -i socket.io #if the request contains socket.io acl is_chat hdr_dom(host) -i chaturl #if the request comes from chaturl.com use_backend chat_backend if is_chat is_soio backend www_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout server 5000 timeout connect 4000 server server1 localhost:6060 weight 1 maxconn 1024 check #forwards to apache2 backend chat_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout queue 50000 timeout server 50000 timeout connect 50000 server server1 localhost:5558 weight 1 maxconn 1024 check #forward to node.js app The problem comes when i made a request to something like www.chaturl.com/index.html it load perfectly but fails to loads the socket.io files (www.chaturl.com/socket.io/socket.io.js) why it redirect to apache (and should redirect to the node.js app that serve the files). The weird thing is that if i access directly to the socket.io file, after refreshing a few times, it loads, so i suppose is "caching" the forwarding for the client when it makes the first request and reach the apache server. Any suggestion of how this can be solved? or what i can try or look about this?

  • Use Apache authentication to Segregate access to Subversion subdirectories

    - by Stefan Lasiewski
    I've inherited a Subversion repository, running on FreeBSD and using Apache2.2 . Currently, we have one project, which looks like this. We use both local files and LDAP for authentication. <Location /> DAV svn SVNParentPath /var/svn AuthName "Staff only" AuthType Basic # Authentication through Local file (mod_authn_file), then LDAP (mod_authnz_ldap) AuthBasicProvider file ldap # Allow some automated programs to check content into the repo # mod_authn_file AuthUserFile /usr/local/etc/apache22/htpasswd Require user robotA robotB # Allow any staff to access the repo # mod_authnz_ldap Require ldap-group cn=staff,ou=PosixGroup,ou=foo,ou=Host,o=ldapsvc,dc=example,dc=com </Location> We would like to allow customers to access to certain subdirectories, without giving them global access to the entire repository. We would prefer to do this without migrating these sub-directories to their own repositories. Staff also need access to these subdirectories. Here's what I tried: <Location /www.customerA.com> DAV svn SVNParentPath /var/svn # mod_authn_file AuthType Basic AuthBasicProvider file AuthUserFile /usr/local/etc/apache22/htpasswd-customerA Require user customerA </Location> <Location /www.customerB.com> DAV svn SVNParentPath /var/svn # mod_authn_file AuthType Basic AuthBasicProvider file AuthUserFile /usr/local/etc/apache22/htpasswd-customerB Require user customerB </Location> I've tried the above. Access to '/' works for staff. However, access to /www.customerA.com and /www.customerB.com does not work. It looks like Apache is trying to authenticate the 'customerB' against LDAP, and doesn't try local password file. The error is: [Mon May 03 15:27:45 2010] [warn] [client 192.168.8.13] [1595] auth_ldap authenticate: user stefantest authentication failed; URI /www.customerB.com [User not found][No such object] [Mon May 03 15:27:45 2010] [error] [client 192.168.8.13] user stefantest not found: /www.customerB.com What am I missing?

  • Can I tell if crashplan has backed up a particular file in a particular state?

    - by Chris Cogdon
    I would like to be able to tell, programmatically, if CrashPlan has backed-up a particular file, including the current updates to that file. I.e., that the current contents of a file are backed up. It's relatively easy to tell when CrashPlan last backed up a file: its file name appears in /usr/local/crashplan/log/backup_files.log.0, and with some accuracy, I could compare the backup time with the last modification time to the file, but that method appears to be somewhat dubious. A couple of methods I could think of, but I don't know how: Compare the current file to CrashPlan's metadata about that file. This needs knowledge about the format of CrashPlan's "cache" files as well as the hashing system used. This might be achievable through the CLI, but the CLI is just a portal into the GUI, and I need something that's scriptable. Restore the file to a temporary directory, and compare it. Unfortunately, there is no CLI to do restores; the GUI is the only way. I'll describe what I'm trying to achieve. It would be nice to know how to do the above, even if there are alternative methods for the following: I'm using CrashPlan for continuous backups to my PostgreSQL database, using WAL archives. In the current configuration, the archive command copies the files to an archive directory, which is backed up by CrashPlan. Every so often I manually confirm (or just trust) a group of WALs are backed up, and remove them from the archive directory, and occasionally do a restore through the GUI to ensure I can retrieve current and "deleted" WALs. The xlog directory is backed-up, too, so I have a good chance of doing a near-full restore even if a particular xlog hasn't been archived by PostgreSQL yet. I'd like to be able to automate this process, which necessitates either confirming the backup status and recency, or automating a restore for comparison purposes. (As a bonus, if the method is trustworthy, I could turn the "archive_command" from "copy to archive directory" into "confirm CrashPlan has backed up the current version", and do away with the archive directory completely). (And, yes, I'm doing regular pg_dumpall's, in addition to the above.)

  • Websockets Server with Fault-Tolerance and Durable Message Store

    - by smitchell360
    I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for. EDIT So, after some research the following installed options seem to be the most robust: Kaazing Migratory Migratory (http://migratory.ro) Hosted services that seem "real" Pusher (great API but no history feature yet) PubNub (has history) All of the above services have graceful fallback to other communication methods if websockets are not available. I was not able to find any open source that provided "out of the box" clustering, fail-over, and a durable message store to play back history. There are some projects that may serve as good starting points, but not exactly what I am looking for.

  • Sending Mail from Web App to Google Apps won't work - internal routing? VPS

    - by Charlino
    I've got a web application, www.mysuperwebapp.com, which sends out emails for various reasons - the contact us page is a good example. I am using google apps on the domain and I've setup a google apps group, Support ([email protected]), which I want the emails from the contact us page to go to. But the emails don't seem to be sending... I thought it could be that the groups security is a little tighter than normal email, so I change the contact us email to go to [email protected] - but they still didn't appear. So I'm guessing that it has something to do with internal routing and the messages aren't leaving the server/network at all. Eg Sending an email from the mysuperwebapp.com computer to a mysuperwebapp.com email address. I put an entry into the hosts file for 123.123.123.123 mysuperwebapp.com but that doesn't seem to have helped. Also, there doesn't seem to be anything of interest in the event log. What do I need to do? Or what do I need to get my VPS hoster to do? TIA, Charles Ps. The VPS is a Windows 2008 box with IIS7 and the default SMTP (IIS6?) server. The web app is ASP.NET MVC - not that that should matter.

  • How should I configure my Active Directory servers so that if one goes down, users are not kicked off SQL?

    - by Matty Brown
    Today, we shut down one of our Active Directory servers during office hours to check the loading on a UPS. Since all the server did was provide Active Directory in a separate building incase the main building caught fire, or whatever, we didn't think it would have any effect on our users. Seconds after the server was shut down, we had a dozen phone calls from users experiencing this issue:- [Microsoft SQL Server Login] SQLState: '28000' [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with authentication. Once we realized what had happened, we quickly rebooted the down Active Directory server. Problem solved. But why did this happen. And what if one day a server has a breakdown and is offline for hours, or days? Shouldn't the other Active Directory servers in the domain service authentication requests without disruption to users? We have 3 Windows Server 2003 Standard servers running Active Directory as Domain Controllers with Global Catalogs, all physically located on the same network at Gigabit speeds. I believe the domain was originally Windows Server 2000, or maybe even NT 4.0. Could the issue be to down to old Group Policies inherited from these old server OS's, or some default setting in Active Directory that needs changing?
