  • Hang while starting several daemons

    - by Adrian Lang
    I’m running a Debian Squeeze AMD64 server. Target runlevel after boot is runlevel 2, which includes rsyslogd, cron, sshd and some other stuff, but not dovecot, postfix, apache2, etc. The system fails to reach runlevel 2 with several symptoms: The system hangs at trying to start rsyslogd Booting into runlevel 1 works, then login from the console works Starting rsyslogd from runlevel 1 via /etc/init.d/rsyslog hangs Starting runlevel 2 with rsyslogd disabled works But then, logging in via console fails: I get the motd, and then nothing Starting sshd from runlevel 1 succeeds But then, I cannot login via ssh. Sometimes password ssh login gives me the motd and then nothing, sometimes not even this. Trying to offer a public key seems to annoy the sshd enough to not talk to me any further. When rebooting from runlevel 1, the server hangs at trying to stop apache2 (which is not running, so this really should be trivial). Trying to stop apache2 when logged in in runleve 1 does hang as well. And that’s just the stuff which fails all the time. RAM has been tested, dmesg shows no problems. I have no clue. Update: (shortened) output from rsyslogd -c4 -d called in runlevel 1 rsyslogd 4.6.4 startup, compatibility mode 4, module path '' caller requested object 'net', not found (iRet -3003) Requested to load module 'lmnet' loading module '/user/lib/rsyslog/lmnet.so' module of type 2 being loaded conf.c requested ref for 'lmnet', refcount 1 rsylog runtime initialized, version 4.6.4, current users 1 syslogd.c requested ref for 'lmnet', refcount now 2 I can kill rsyslogd with Strg+C, then. /var/log shows none of the configured log files, though. Update2: Thanks to @DerfK I still have no clue, but at least I narrowed down the problem. I’m now testing with /etc/init.d/apache2 stop (without an apache2 running, of course) which hangs as well and looks like an even more obvious failure. After some testing I found out that a file with one single line: /usr/sbin/apache2ctl configtest /dev/null 2&1 hangs, while the same line executed in an interactive shell works. I was not able to further reduce this line while, i. e. every single part, the stream redirections and the commando itself is necessary to reproduce the hang. @DerfK also pointed me to strace which gave a shallow hint about what kind of hang we have here: wait4(-1for the init scripts futex(0xsomepointer, FUTEX_WAIT_PRIVATE, 2, NULL for rsyslogd / apache2 binaries called by the init scripts The system was installed as a Debian Lenny by my hoster in autumn 2011, I upgraded it to Squeeze immediately and kept it up to date with Squeeze, which then used to be testing. There were no big changes, though. I guess I never tried to reboot the system before.

  • ESXi configuration

    - by Simone Falcini
    I just bought a dedicated server on online.net I have a public and a private ip. I installed esxi from their panel and I can connect successfully with my vsphere client. The problem is this: I want to create some instances and I want to give them different private ips. I also want to create some NAT rules to forward all users coming to my public ip port 80 to a specific instance. How can I do that? Thanks

  • Same password for apache and samba with ldap?

    - by barbarossa12d
    Hi, I am experimenting with LDAP. As I see it, apache uses the Unix password field to get the credentials and samba the field that is specific for samba. I just use the LDAP server for a single server, LDAP runs in the same server. What I wanted is to use the same password for apache and samba (and mediawiki etc). Is it possible? If not, are there any alternatives? Thanks!

  • Is there a way to automatically switch profiles for a RAT mouse?

    - by MBraedley
    So I bought a Cyborg RAT 7 mouse a while back, and I love it, except for one thing: it's not automatically selecting the profile for the game I've just started. This is annoying because, for instance, I have the forward and back buttons, as well as the side scroll set up for weapon selection in some games, and if the proper profile isn't selected before starting the game, none of it works. How can I get my mouse to load the proper profile when I start up a game?

  • Connect to powershell through SSH with keyexchange?

    - by Lucas Kauffman
    I have little experience with Windows systems. Coming from a Linux background I was wondering if there is a way that I can ssh to powershell from a Linux shell? If this is not possible, is there a key exchange like way to connect from powershell to powershell? I prefer it if I do not need to enter a password for every single server every time. If this all sounds a bit crazy and there are better ways that windows does this, then feel free to share.

  • Blade Enclosure, Multiple Blade Servers, Whats the closest approximation to a DMZ?

    - by codeulike
    I appreciate that to get a proper DMZ, one should have a physical separation between the DMZ servers and the LAN servers, with a firewall server in between. But, in a network consisting of a single Blade Enclosure containing two or more Blade servers, whats the closest approximation to a DMZ that could be designed? More details: Virtual servers, mostly Windows, running in a VMWare environment on the Blade servers, and physical firewall box between the Blade enclosure and the internet.

  • Record browsing history

    - by nc3b
    How can I record everything I browse so that, ideally, it might later enable me to re-surf the same pages without internet access ? For instance, if I go to http://www.example.com/example.html I would like to be able to view the same page later exactly as initially (but without reconnecting to www.example.com). Thank you in advance.

  • How do I force my Graphite Airport to distribute 192.168.x addresses instead of 10.x.x addresses?

    - by William
    I'm sharing a single IP address but there's no way to change what network it uses for distributing the private addresses via DHCP. My problem is that my VPN to work already uses the 10.x.x network, so I'd like my home to use 192.168.x. I've tried messing with the Network tab within the Airport Admin Utility for Graphite and Snow but nothing works. I'm hoping there's some way to hack the configuration file.

  • Solaris WANboot & Jumpstart SPARC/x86

    - by watain
    I need to setup a Solaris WANboot and a Solaris jumpstart server for both SPARC and x86 architectures. Can I setup both on a single machine (SPARC or x86) or do I need a separate SPARC and x86 machine to jumpstart a SPARC respectively a x86 client? As far as I know the architecture of a WANboot server doesn't matter, as long as the correct Solaris flash archive is used. Best regards

  • Windows 7 Remote Desktop Connection Rendering Each Frame?

    - by TheDarkIn1978
    When connecting to my work computer over VPN and Remote Desktop Connection, images and videos are sent back one frame at a time, which really slows things down. I'm familiar with the "Experience" tab while connecting and the only options I have checked are "Visual styles" and "Persistent bitmap caching". Isn't it possible to work remotely that is more similar to screen sharing over Skype, where there is a lag but not every single frame has to be rendered and passed back to me one at a time? Both computers are running Windows 7 Professional.

  • SQL Server: Statements vs. Batches vs. Transactions vs. Connections

    - by Sleepless
    My question is simple: What are the differences / similarities / cardinalities between Transactions Batches Connections and Statements in SQL Server? As far as I understand a connection is a single communications channel between a SQL Server instance and a client within which collections of statements grouped as batches are executed. A batch is either implicitly or explicitly mapped to one or several transactions. Is this correct?

  • What is the best way to remove duplicate files on web hosting's FTP server?

    - by Eric Harrison
    For some reason(Happened before I started working on this project)- my client's website has 2 duplicates of every single file. Effectively tripling the size of the site. The files look much like this: wp-comments-post.php | 3,982 bytes wp-comments-post (john smith's conflicted copy 2012-01-12).php | 3,982 bytes wp-comments-post (JohnSmith's conflicted copy 2012-01-14).php | 3,982 bytes The hosting that the website is on has no access to bash or SSH. In your opinion, what would be the easiest way to delete these duplicate files that would take the least time?

  • Where does Tomcat cache my taglib .jar files?

    - by NogginTheNog
    I'm deploying a .jar file to a tomcat instance (we're running 6.0.18 on Redhat linux) and according to the log output the old .jar is still being used. I've restarted everthing I can think of, have deleted the work directory etc.etc. but to no avail. I'm no tomcat expert, so here's my question: where should I look for to ascertain if tomcat is using a cached jar and how should I prevent it from doing so?

  • Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

    - by Alexander
    I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: 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) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

  • raid 6 vs raid 10? which would you choose.

    - by dasko
    my choice would be raid 6 for a file server since you can lose two drives and it does not matter which set of two can die. from what i understand with raid 10 you can lose two drives but if they happen to be off the same raid 1 then you are a out of luck? any suggestions? basic file server with about 200gb of data and it would act as a single point of backup for other workstations and servers. thanks in advance.

  • Can Office365 (Enterprise) sync from a remote LDAP server?

    - by kez
    I am looking in to the details of a migration to Office365 - primarily for the use of hosted Outlook capability. I see that the Enterprise plans have "Active Directory Sync", but details seem scarce. Is it possible to sync an independent LDAP server (such as Apache Directory) up to O365 (I want to keep it separate), or would I need to host a local instance of Active Directory and use that to sync users up to O365?

  • SQL Server: error when connecting

    - by atricapilla
    (migrated from stackoverflow) The application I'm using tries to connect SQL Server named instance running on a dedicated database server. Here's the error I'm getting: The TCP/IP connection to the host <instance_name>, port 1433 has failed. Error: Connection refused: connect. Is the firewall blocking my access or what? Should I dedicate a different port for this application?
