Server inaccessible

After installing and starting Sun Java System Application Server PE-9.0, its services are inaccessible on localhost.
Messages received when starting the server indicate, that everything is all right:
"Domain domain1 is ready to receive client requests. Additional services are being started in background......"
Nonetheless, the web browser just displays the cursor clock saying "waiting for localhost...", but nothing happens afterwards.
It is the same with all service ports (8080 8181 4848 3700 3820 3920 8686).
I do not experience such access problems with Tomcat.
OS: Suse 10.1
No firewall is blocking.

You can use both Bonjour (multicast DNS) and traditional DNS (unicast DNS) together.  Your clients can use your own DNS server to access LAN-local services, and Bonjour where that's appropriate (eg: client to client, server to client, etc).
To do the internal and external demarcation, register two domain names.  I usually use different TLDs on the same domain, and registering and holding a few extra of these domains means you won't have "fun" later, as the DNS namespace continues to fill up.
You can then use the external domain name for hosted mail services and stuff that's accessible outside your LAN, and that'll be the domain name that's listed in the hosting service's or your ISP's public-facing DNS.
Your internal network uses your own DNS server, and your DNS server then provides translations for your static-addressed devices on your network (eg: network printers, your external gateway-router-firewall device, any NAS devices, your Mac OS X Server box, etc), are referenced in your local DNS using your internal domain name.  Your internal domain name and your local host translations are all used within your private DNS server configuration, and the translations are not accessible outside your LAN; you need to be connected to your LAN directly, or via VPN.
Using the two domain names means you don't have to manage the same domain name for both internal and external sites, and the external DNS services.  You're managing two separate and non-overlapping domains this way, rather than one domain name that has two seperate and authoritative servers active.
There's a whole lot more detail in that DNS article you're probably reading by now, too.

  • Changeip hostname to name.local rendered server inaccessible most of the time

    I followed the instructions here:
    http://maymay.net/blog/2007/09/19/changing-the-hostname-on-mac-os-x-server/
    According to Apple, I also have to change the hostname somewhere else.
    http://support.apple.com/kb/TA24015
    "Before running changeip, be sure you have updated the server's hostname in DNS to match the hostname provided to changeip; otherwise errors will be logged in system.log, and services may not function properly".
    I am not if you have followed my plight before currently running DNS so I changed it as described in the blog post above to be the bonjour name. Sometimes I can access it at [email protected] On some computers 100% of the time, and on some computers not at all. This may very well have to do with whether or not they are on the same subnet.
    What I'm wondering is did I use the changeip command correctly, or should the unix name be separate from the bonjour name? When I first set it up, it seemed to function once I enabled DHCP. I was trying to solve a daylite problem originally. c'est la vie.
    I am primarily trying to use it as a local file server/daylite server. Daylite mostly functions, while the file server does not. I hope this isn't extraneous information. Probably I need to access it via IP?
    I'll post the original Daylite KB article if that would be useful to you.

  • E4200 router, wmp600n wireless adapters and mapped drives with wpa2 don't work!

    Sigh
    I have a file server running windows 2003 and five computers (1 windows 7, 4 windows xp-sp3).
    There are two shares on the server.
    When the router is setup with wpa2, three of the windows xp machines will have problems with mapped drives. Directly after the drives are mapped, everything works, but 10 or so hours later, users can no longer access these mapped drives and there is no way to reconnect them it seems.
    The other two machines (windows 7 and one windows xp machine) have no problems whatsoever.
    The only thing that the three computers have in common is that they are also sharing a printer (an hp j4680) attached to one windows xp machine (not the server).
    If I set everything to wpa, everything works fine, but of course my wireless network speeds drop to 56mbps.
    Thoughts?

    Peanut, I appreciate your effort, but I don't think you truly understand what is going on.
    FWIW and for those experiencing similar oddities, On a mixed network of Windows Server 2003, Windows XP and Windows 7 machines, several Windows XP machines would on boot up decide that the router was the master browser. This made file shares on the server inaccessible to these machines. All machines were using wmp600n adapters.
    All computers had excellent signal strength and could access the internet without fail.
    What was not immediately evident to me was I was also having email issues where certain XP machines could not receive or send (sometimes one, sometimes both) pop email. I suspected it was a port blocking issue by the ISP since this problem was intermittent.
    What was clear though is that in each of the machines that exhibited the problem that computer was seeing the browser as the browser master. So finally, I swapped out the router with another branded router. This is not the only case of this router behaving this way--in my searches I have run into several other people who have had issues with file sharing so I don't know if it is a model deficiency or firmware issue.
    All I know is the all the problems went away with the router switch.  File shares work. Email works.
    So, I got a bad router that appeared to function properly--assuming this is not the case with other e4200s. I will know after RMAing this one.

  • Upgraded to DW CC 2014.1, FTP/SFTP isn't working at all

    There's a HostNexus webserver I usually connect to but since I upgraded to DW CC 2014, it only spits back errors. I can connect successfully to the server in FileZilla (using FTP explicit). I've looked through the forum and tried various suggestions but none have worked:
    tried all the FTP modes
    --> FTP Explicit: The remote host actively refused the attempt to connect to it. This may be due to 1. destination server name or IP address, 2. port number, 3. server inaccessible, 4. incorrect protocol or settings.
    --> FTP Explicit with passive: The remote host actively refused the attempt to connect to it. This may be due to 1. destination server name or IP address, 2. port number, 3. server inaccessible, 4. incorrect protocol or settings.
    --> FTP: An unknown error occurred.
    --> FTP with passive: An unknown error occurred.
    --> FTP Implicit: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
    --> FTP Implicit with passive: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
    reset preferences
    specified root folder
    contacted HostNexus, they said to change settings to SFTP, port 4000
    --> User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
    shut down my antivirus/firewall
    --> Same error: User limit reached or not authorized to make the connection due to local firewall blocking FTP data.
    made sure not connected through any other program
    uninstalled CS4
    Nothing works.
    I really want the efficiency of being able to do everything with DW. What else can I try?

  • Fresh install of Server 2012 R2 causes inaccessible boot device on first Reboot

    Hello Everyone, 
    Doing a fresh install of Windows Server 2012 R2 on a SuperMicro X9DRT-HF+ motherboard based server. The server is using iSCSI boot, setup detects the iSCSI disk and copies its files, finishes the "Getting files ready for installation" "Installing
    Updates" phase, reboots, takes a while and eventually gives a Blue screen with Inaccessible Boot Device error. I have tried some changing options in the BIOS, I've had Nimble (storage array) support on the phone and they confirmed the setup is correct
    but for some reason after the first reboot Windows can no longer find its install files and gives a BSOD.
    Additional Information: 
    Server: SuperMicro X9DRT-HF+ (no internal disk)
    Storage: iSCSI disk provided from Nimble CS220 Array
    Windows 2008 R2 Server installation will proceed without any problems.
    I checked the \Windows\Panther\Setupact.log / CBS.log file and there doesn't seem to be anything indicating a problem. 
    I have googled a number of times to find solutions but most articles reference a similar problem after installing a particular KB (which shouldn't be the case here). Need some help :) 

    Hey Tim,
    Thanks for your reply, since the start of this post I have also installed MDT to try a different approach to installing the OS. Using MDT I have injected the Intel I350 driver into the installation so it should be restarting with the driver loaded.
    The odd thing is that when the server reboots the Windows startup screen loads for about 4 minutes before it gives the INACCESSIBLE_BOOT_DEVICE error. This would indicate to me that it sees the disk and tries to boot from it but then something goes wrong.
    Other than the \Windows\Panther location is there another place I should be looking for log files during this part of the Windows install? I have reviewed all the locations listed under the TechNet library article "hh824819" (I can't post
    a link to the article but a google search brings it up) but I can't seem to find a log of when the server crashes what it is doing at that point.

  • OS X SERVER "Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible."

    We have an OS X 10.6.8 SL server managing our iMacs. Since the update of the workstations to at least 10.6.8 and Firefox 34.0.5, we get the error: [Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.] upon launch of Firefox. It appears to be an issue that the profile is stored on the server rather than on the local hard drive. There is no way whatsoever to access, configure, start, or any other way manage Firefox at this point. Need a solution to this problem as we have hundreds of users that are unable to use Firefox now.

    See:
    *https://support.mozilla.org/kb/how-run-firefox-when-your-profile-missing-or-inacc
    This is usually caused by a problem with the profiles.ini file and the profile marked as Default=1 in this file is no longer present on the hard drive.

    CS4 Premiere: Can't open due to inaccessible to Importer Process Server:
    Dear Guru:
    After subject:
    I uninstalled it;
    Re-installed it;

    No luck, same error message ...
    A friend's wedding reflash is set on 12/22, I have yet to open my Premiere?!!! Heeelp... Please...
    Appreciate !

    Hi, Jeff:
    My system is XP; before the premiere worked well.
    More detail story: Premiere could not open 3 days ago, no fix, some one sent me a crack software, I used it, no luck. Another nice guy told that is for non-legal Premiere, surely it won't work.
    I tried to remove Premirere; difficult; some one suggested me to use Adobe CS4 cleaner from Adobe. Then it was removed. I re-install Premiere; During the process, abnomal thing I remember was: I can't input product S/N, so I had to use 30-day trial.
    During the installation, it was stopped by Windows Installer issue, I restarted Windows Installer, then the process continued...
    I have two log files, don't know how to attach into this message. But, can't find any problem therein.
    Heverever, when I tried to open newly installed Premiere, error message says: ---can't open, reason is exactly same with very beginning: Can't communicate with Inporter Process Server....

  • MDT database inaccessible server error

    Hi
    Every time I try and add a database connection, I get an error stating inaccessible server. I have tried this on various databases and mdt servers. I am running MDT2010 and sql server 2005 SP3
    Thanks
    Paul

    I did this to solve this problem, I'm not sure whether all of them are needed;
    1. Created a new login in "SQL Server Management" to be used - no go
    2. Opened up firewall rule to allow port 445 (which is used by named pipes) on SQL Server- this is needed, but still no go! (I had previously also opened port 1433 and port 1434).
    3. Created allow PING rule (ICMPv4) on SQL-server - problem solved!
    It seems like the MDT wizard is dependent on being able to ping the SQL-server in order to make a Connection to it. Not very brilliant...

  • WAN IP inaccessible from within LAN (MacMini Server)

    Hi!
    I'm having a bit of a networking problem that's exhausted my (pretty basic) understanding of DNS and basic networking. It's the kind of thing that i imagine has a quick fix, just one that in my fairly limited experience i've not yet come across. Hopefully someone on here will be able to help.
    *Office setup:*
    Mac Mini server running OS X 10.6.4 (at 192.168.2.250)
    ~6 client iMacs, all running OS X 10.6.4
    DrayTek Vigor 2820 router connect to the web with a static IP (at 192.168.2.1)
    Problem:
    Our WAN IP address appears inaccessible from within the LAN.
    Normally this doesn't cause any problems but increasingly, as we start to make better use of features such as the iCal and Address Book servers, we are encountering stags.
    Take iCal for example. The client machines connect to iCal server via the internal server domain (macserver.private) - this works great. To access iCal server from outside the office (eg. on iPhone) we connect via a subdomain of our company domain ('ical.ourcompnay.com') which points to our office WAN IP. (The nameservers for 'ourcompany.com' are on our webserver, not in the office.) This also works great, until you bring the iPhone or laptop into the office, at which point the WAN IP, pointed to by 'ical.ourcompnay.com', is inaccessible.
    By inaccessible i mean that when you try to browse to the IP in Safari, a page simply never loads. And when you 'traceroute' it, you simply get no return.
    Aim:
    The aim is to be able to use the WAN IP inside the LAN exactly as we can from outside the office. Or to discover some workaround that delivers comparable behavior.
    *Other info:*
    The client machines' network preference are all set with DNS serves of both 192.168.2.250 (server) and 192.168.2.1 (router). For some reason (that i'm not able to explain) clients are unable to access the internet unless the router's IP is specified in addition to the server's, despite the server specifying the router as the 'forwarder address'.
    If there's any essential info that i've missed out then please let me know and i'll fill any gaps straight away.
    Thanks in advance for any help.

    Camelot - thanks for your reply!
    Note, there may be some setting in the router that controls/allows this
    I thought that there may be something in the router configuration that would solve my problem but have so far had no success. The most useful looking thing I can find is called 'Static route'. Setting up a static route requires just 4 parameters: Destination IP Address, Subnet Mask, Gateway IP Address, Network Interface (ie. WAN or LAN).
    My understanding of this feature is that it is intended for facilitating networks with multiple routers so i'm not sure that it's going to help me. Unfortunately, as much as i Google i don't seem to be able to fully get my head around subnet masks so it's hard for me to know if a static route will ever be able to help me. Any thoughts?
    The alternative is to configure your own internal DNS server as being authoritative for ourcompany.com
    I initially thought that this would solve my problem too but i'm now not so sure. The client iMacs all had to be manually configured to use the server (192.168.2.250) as their DNS server. By default devices connected to the network inherit the router's DNS servers (external to the LAN). So surely even if the the server's DNS server was authoritative for 'ourcompany.com', this wouldn't actually get queried by 'temporary' network members (iPhones, laptops etc.)?
    you have set the server to allow localnets to resolve, right?
    I think so. In the DNS server settings (in Server Admin) 'localnets' is listed under 'Accept recursive queries from the following networks:'. 'localhost' is also listed.
    nslookup www.apple.com 8.8.8.8
    This works fine, both from the server and from clients.
    I too am a little worried that both server and router must be listed for the clients' DNS servers. I'm no expert (as you can tell!) but when setting up the network i wasn't particularly satisfied by this, it felt like a bit of bodge.
    Thanks for your help so far.

  • Remote Desktop in Server 2012 is inaccessible from outside of LAN

    We have a server 2012 machine it was setup and accessible via Remote Desktop for months.  A few days ago we wiped it and did a fresh install of Server 2012.  Now we can not remote to the server from outside of the LAN, even though it is setup exactly
    as it was before. 
    Here is a checklist of things I have checked while trying to figure out the break:
    Router/firewall is forwarding port 3389 to the correct internal static IP of the server.  Port forward test tools online confirm the port is open.
    Windows firewall is set to allow all connections for Remote Desktop on 3389.  Also tried turning off firewall completely, does not fix the issue.
    Allow remote connections is enabled in System Properties, and users have been added to the list of allowed user
    Additional info:  The server is also a standalone Active Directory and Domain Controller.
    Remote desktop connections work fine while in the office on the LAN.  When remoting to the external IP, it doesn't work, even though it did only days before we re-did the server.
    Thanks!

    What should I check in AD?  I am by no means an expert with AD.
    Yes, I am using the same client OS.
    I am talking about RDP over the internet, like from home to the office.  We have a static IP assigned to the router from ISP.  A static internal IP assigned to the server on the LAN.  And the router port forwards 3389 to the assigned IP. 
    It was working fine before we reinstalled Server 2012.  These are the steps I took when reinstalling:
    1. format drive and install OS
    2. rename the server
    3. install SQL server
    4. Install TFS and SharePoint
    5. Add Active Directory role and promote to Domain Controller
    6. Add domain users
    7. Enable remote access on the server and add users to remote access list

  • Printing Word documents to PDF from Office Web Apps Server 2013 yields inaccessible PDF files

    I have Office Web Apps Server 2013 SP1 with March 2015 CU applied. The version shows up as "15.0.4569.1506" using Todd Klindt's
    method. When anonymous users view the Word documents online through the Office Web Apps, they have an option to print them to PDF. The PDF file that gets generated as a result isn't accessible
    (i.e. it isn't WCAG-compliant). using Adobe Acrobat Pro to check it I can see that it is missing tags, for example. The source Word document was made fully accessible from the point of view of Microsoft Office accessibility tools.
    When viewing the same document in Word Online in Office 365, I get an extra option  "Download as PDF". The PDF document produced is accessible. If I save a Word 2013 document as a PDF from within the Word editor, it also generates accessible
    PDF.
    I was wondering if the reason for the accessibility problem that I have misconfigured my on-premises Office Web Apps,  or perhaps the accessibility compliance isn't built in yet. If the latter is true, I was wondering if someone could indicate whether
    or not this is on the list of upcoming CUs.
    thanks in advance. 

    Just check my WAC install, no this is likely an Office online only feature, at least at this point in time.

  • Remove inaccessible/inactive exchange 2010 server

    I had a second exchange 2010 server with a DAG setup between the primary production exchange 2010 server and the secondary one which was at our DR site. I did a DR test and ended up having to break the DAG and mount the DB manually for the DR test. AS a
    result this second exchange server has been switched off and I have removed the DAG from the production side and all is ok with that. I am planning to move to a netapp exchange replication solution instead of dag for DR. As the DAG does not work well as a
    DR solution.
    The only problem that remains is that I still have the old server listed under servers and there is a public folder database that is still listed from the second server. Is there a way to remove this inasscible server from exchange without doing it through
    ASDIedit? There is no way that i can turn this second server on again.

    Your first option is to uninstall normally as commented by Ed.
    If no way you can uninstall (in a documented way), then you can go with the final option of cleaning up from active directory. But take a backup of the active directory system state before doing this to be safe.

  • Time machine backups inaccessible after reconfiguring OS X Server

    I'm having a Time Machine issue.
    I back up to a Mac Mini running Mac OS X Server 4 on Yosemite 10.10.1.  The Time Machine service is turned on and pointing to a volume directly connected to that Mini.  The machine backing up to the server is a MacBook Pro Retina, running Yosemite 10.10.1.
    Recently, the volume holding the backups got full.  I copied the "Shared Items" directory to a larger volume and changed the Time Machine service to use that volume.  Everything seemed to be fine.  At the time for the next scheduled backup, the laptop connected to the server, and backed up a reasonable amount of data.  Subsequent backups have also run without obvious problems.
    Then I wanted to revert to an earlier version of a document on my system.  With the document's containing folder open in the Finder, I chose "Enter Time Machine".  The TM interface opened, and I saw the usual stack of windows disappearing back into the past.  However, after a few seconds, the title bars on all but the most recent couple of those windows went blank, and I was unable to go back to to any backups created before the changes on the server.  The timeline on the right shows backups back to October 5, and nothing is dimmed, but clicking on those older dates does nothing.
    I tried this with several other folders, with the same results.
    I mounted the backup image manually on the server.  I was able to browse the stored backups on that image, and navigate to the same folders, which do contain the content that they should.
    So, it seems as if the backups are intact, but for some reason Time Machine can't navigate to those older backups.
    I tried re-selecting the backup volume in the System Preferences, and I got the dialog telling me that the backup volume already contained backups from this machine, and asking if I wanted to erase and start fresh, or use those backups. I chose to use the backups, and this triggered an immediate backup, which was successful and once again backed up a reasonable amount of data.  But, still the same problem with going back in time.
    I would prefer not to have to start a new backup set if possible.  Any help would be appreciated!  I browsed the various questions and problems on pondini.org but did not find anything that seemed directly applicable.
    Thanks!

    Hi,
    Quitting Dropbox and rebooting the computer did not solve the issue.
    However, I read on another thread here that there is a workaround, which is to enter the Time Machine view from the window of your hard disk, then navigate back in time, and then navigate to the folder that contains the items you want to restore.
    Time Machine not working with Yosemite
    I tried this, and it seems to work fine.  Folders that behave in the broken fashion I describe above (no ability to scroll back when entering Time Machine from that folder) are accessible by starting from the hard disk and navigating down.
    There are a lot of people reporting this problem in the other thread, so my guess is that this is an Apple bug in Time Machine that needs to be fixed.  In the meantime, at least I can restore most files I might need, except files in an invisible folder like ~/Library.
    Thank you for your help!

  • Server Preferences Inaccessible

    I recently purchased the Mac Mini and Snow Leopard Server to replace an old server that went out. I have installed the server software twice now because after about a week my clients are unable to access the server. When I log into the server as an admin I try going to server preferences where I set up the users accounts, sharing, etc. It's a simple setup in all we are using the server for is file sharing. However, now when I try accessing the server preferences it pops up a window asking for the server, user name and password. All the default entries don't work and I'm at a loss as to why this is requesting this, why it's doing so after a week of flawless performance and how do I resolve it.
    My guess is that something to do with this is why we can't access the server from a client. Any help would be great!

    Frankly, when it comes to servers I'm very inexperienced.
    Running servers is a bit more involved than running clients, unfortunately. Which means you'll be learning on-the-job, or classes or manuals or however you learn best, or working with Apple support or a local service provider.
    I checked to confirm DNS and it came back as hostname is not available. I remember it asking me about this at setup. I wasn't sure what to put in there since the server is not used for any external services such as email, remote access, etc. just internal file sharing. I suppose this could be the culprit, but what I don't understand is why it worked fine for a week or so before going bonkers yesterday mid-afternoon.
    Getting DNS operating and stable is a prerequisite for the rest of the stack.
    (Deja vu, too; had a customer's DNS tip over yesterday, too.)
    Anyway, I'm not sure how to correct this or what to do to get it setup since my only experience with DNS is for websites.
    To do a full DNS setup on the box rather than the default just-the-local-host set-up that the configuration tools leave you with, read [this|http://labs.hoffmanlabs.com/node/1436] as a start. The full local DNS set-up may be overkill for your requirements here, but (if "changeip -checkhostname" is balking) you're definitely going to have to figure out why your DNS isn't working correctly.
    As for your other questions regarding WGM, I haven't used it at all. Not on the server, not remotely.
    WGM is your friend here, when you're setting up usernames for network (distributed) access. But get DNS stable.
