Apache @ centos issue (hostname changed by mistake)?

Hi there!
I have a VPS and the hosting enterprise reboot it (don't know why), and i had configured apache correctly until this. Now, when i start apache theres an error: "Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName"
So, the hostname has changed to its default value, is there a way to get the old hostname? Maybe on the apache logs? The VPS provider does not answer my messages...
Thanks and greetings....

I think it impossible to say what happened without knowing more details.
You can type the command hostname to check what the current host name is. You can set a hostname until the next reboot by using hostname new_name.
To set a permanent hostname on Debian based systems, check and modify +/etc/hostname+. On Red Hat based system check +/etc/sysconfig/network+. You should also check /etc/hosts to make sure it is set accordingly.
You can search for the old hostname by looking in the old messages logs in +/var/log+ and apache logs in +/var/log/httpd+ or +/var/log/apache+.

  • UCCX Hostname Change

    Hi,
    is there a way to change the hostname of UCCX 7.0? what should be taken care of if i change the hostname?
    regards
    Prasanna

    Hi Prasana,
    Hostname change is not recommended or supported for UCCX product. Changin the server name causes SQL/MSDE database to not start up which causes major issues.
    Hope this helps

  • Hostname change fantasticality?

    I found a strange thing, my macbook pro hostname change fantastically.
    It looks like when I change a network connection, the hostname will change.
    For example, when I am at home, and issue the command "hostname" in cmd console, it return "bogon". When I am in office, the hostname command will retuen another string.
    Anybody can tell me what's reason?
    Thanks a lots!

  • Issue with changing database location at runtime

    I am having a similar issue to:
    Re: Issue with changing database location at runtime
    where I am using Crystal Reports 2008 SP 3 fix pack 3.3 and a OLE DB connection to a SQL 2008 R2 server. Running on a computer on the network where the report can see the original development server is fast, other computers where that server is not available are hanging 20 seconds before coming up.
    I am using the same code from the Crystal Sample app to change the connection on each table. I found that the slowness comes the first time the ReportDocument object is accessed to get the collection of database tables, before the connection info is set.
    Fix pack 3.4 was mentioned in that post.  Does fix pack 3.4 fix that issue? I don't see fix pack 3.4 on the downloads page (https://websmp130.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/bobj_download/main.htm)

    I just found on the reports that were having the issue there was a SQL Expression.  Per this thread:
    Re: Report load is slow after changing database servers
    There was an issue with that and the fix is not out til the end of Feb so I found a way not to use the SQL Expression and the speed is much better.
    However, your information provided led me to this post:
    Cannot Change Table Location, but Only for One Report
    And I am also experiencing an issue where the table location is not changing on one subreport and I will look into that as a possible solution.
    Thanks so much for your help.

  • IE issues and change browser on BB for safety

    BB's do not run IE, so there is no need to be concerned in that regard. Some BB Browser versions can be configured to run in an IT Compatible mode, but they are technically not IE.

  • Need of hostname change on existing endeca host

    Hi All,
    I have installed all endeca core packages (Mdex6.2.1, Platform6.1.1, Workbench2.1,..) and a pipeline on one of linux box. Now, there is a need of hostname change. Hope it does not break any  existing platform and pipeline. Is there any document related?
    What i can think of on endeca perspective are,
         Hostname change on environment.properties
         URL change on pipeline esp file
         Change eac central server hostname on workbench
         URL change on Preview app setting on workbench
    Is there anything else I need to consider?
    any comments are more than welcome.
    Thanks,

    Take a look at support KB: How to Change IP addresses or host names for Endeca Hosts (Doc ID 1532056.1).

  • CUC 10 hostname change

    Hi,
    Just wanted to clarify the exact procedure for the hostname change for the CUC.
    As for CUCM, Im & Presence the command is set network hostname, however for the CUC the below link does not mention the same.
    http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx.pdf
    Please refer page 75,76 where they stating to use for alternate hostname via command set web-security.
    I have used the set network hostname in CUC and it worked fine.
    Could any one please confirm the exact procedure.

  • Terminal hostname change

    Recently the hostname changed in the terminal from hummingfish to hummingfigh-2.
    Any ideas as to the cause or the fix?
    Thanks.

    This sounds like a localnet problem. I know that the router can supply a hostname that sometimes collides or is derived from the localnet domain name.

  • Hostname change with Distribution Monitor

    We will perform Upgrade&UnicodeConversion for our BI system with Distribution Monitor  parallel export/import function.
    I would like to keep hostname unchanged after export/import to avoid interface configuraiton adjustment,
    Export from HostnameS -> Parallel import to Hostname D -> Change HostnameD to HostnameS when finished (adjust SAP profile & oracle listener), does it work?
    Is there a better idea?
    Thanks,
    James

    Thanks Sunny,
    I've read this note before. I am looking for a smarter way to avoid hostname change with Distribution Monitor.
    Option 1: As I mentioned before, change the hostname back to HostnameS immediately after import in destination server.
    Option2: When import, we can set SAPINST_HOSTNAME on target server, this can be set to HostnameS, but in /etc/hosts files, the IP address of this entry is point to HostnameS, I have not figured it out......
    If there is no choice rather than changing the hostname, then we will follow this note and test all connections/configurations.
    Thanks,
    James

  • Are there any issues with changing IP address of an ACS v5.3 system after initial setup?

    I am migrating from ACS v4.2.1 to v5.3.  I want the final v5.3 system to assume the IP address of the original 4.2 machine so I don't have to change any configs on the network devices.
    Are there any issues with changing the v5.3 system IP address AFTER the initial setup?

    I tried it without a problem. I changed the ip address of the WLC many times.
    You have to make sure though that:
    1-) You change the switchport accordingly to the appropriate vlan if the new ip belongs to a subnet of a different vlan.
    2-) Make sure that all AAA clients configured to use the new IP address of the ACS servers.
    Here is the procedure how to change the ip of the interface (as per cisco doc):
    http://goo.gl/0BYqVT
    I changed also by normal ip address command and it works. but of course the server must be standalone before doing that step (i.e. no secondary ACSs registered to it and it is not registered to other ACSs in a distributoin).

  • SSH Still Working after Hostname change???

    Hi all,
    I was under the impression (from past experiences) that SSH self-signed certificates are made up of the Hostname and the Domain Name of the router.
    I have been working on a customer network and I can see that the SSH RSA certificate is using the old hostname of the device+domain name but SSH still works both inbound and outbound on the VTY lines!
    I thought you had to zeroize the keys and recreate using the crypto key generate rsa command in order to continue to use SSH after a hostname change so that the new certificate contains the new hostname?
    Any explanation would be greately appreciated
    Many thanks
    David

    Hi David.
    Yes after changing router parameter such as Hostname, domain name SSH still works with the old certificate.
    What i can suggest you is to recreate it through crypto key generate rsa command in configuration mode.

  • Svn with Apache Timeout issue

    Hello Archers,
    I've set up an svn Server with Apache folloing your wiki on my raspberry pi.
    https://wiki.archlinux.org/index.php/LAMP
    https://wiki.archlinux.org/index.php/Subversion_Setup
    Unfortunately I get errors when I try to commit several files (15 or so). I think it is a timeout issue, however I don't know where to specify the timeout in the httpd.conf (or httpd-ssl.conf)
    This is a client error message:
    Commit failed (details follow):

    And this the corresponding server side log:

    I assume it is some error like this: http://subversion.apache.org/faq.html#s … -truncated
    I think I don't have specified the timeouts correctly, since I haven't found the default option.

    # SSL Protocol Adjustments:
    # The safe and default but still SSL/TLS standard compliant shutdown
    # approach is that mod_ssl sends the close notify alert but doesn't wait for
    # the close notify alert from client. When you need a different shutdown
    # approach you can use one of the following variables:
    # o ssl-unclean-shutdown:
    # This forces an unclean shutdown when the connection is closed, i.e. no
    # SSL close notify alert is sent or allowed to be received. This violates
    # the SSL/TLS standard but is needed for some brain-dead browsers. Use
    # this when you receive I/O errors because of the standard approach where
    # mod_ssl sends the close notify alert.
    # o ssl-accurate-shutdown:
    # This forces an accurate shutdown when the connection is closed, i.e. a
    # SSL close notify alert is send and mod_ssl waits for the close notify
    # alert of the client. This is 100% SSL/TLS standard compliant, but in
    # practice often causes hanging connections with brain-dead browsers. Use
    # this only for browsers where you know that their SSL implementation
    # works correctly.
    # Notice: Most problems of broken clients are also related to the HTTP
    # keep-alive facility, so you usually additionally want to disable
    # keep-alive for those clients, too. Use variable "nokeepalive" for this.
    # Similarly, one has to force some clients to use HTTP/1.0 to workaround
    # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
    # "force-response-1.0" for this.

  • WLS 8.1 Apache Plug-in is changing HTTP status code 999 to 500

    I'm seeing the weblogic server 8.1 sp4 apache plug-in change the HTTP status code of 999 (set by the application) to 500 Internal Server Error. I'm seeing this with Apache 2.0.48 on aix and with Apache 2.0.58 on windows. I've tried the plug-in from 8.1 SP2, SP4 and SP6 with all yielding the same result. I've tried the SSL plug-in too - same result. I'm told by the maker of this application that they are not seeing this issue with the plug-in for SunOne/NES. What does BEA say about the Apache plug-in changing the http status code? Why is it doing this? Why doesn't the SunOne/NES plug-in do it? Can you provide a plug-in that does not do this?

    Try setting
    Debug ALL
    inside your IfModule. All proxy activity will be written to /tmp/wlproxy.log (on
    unixes). If no info appears in the log, Apache is not invoking the plug-in properly.

    I restarted my wls cluster and apache as well and when I specify http://192.168.10.142/public/testwebapp
    (apache web server) I receive Error 404--Not Found (even thou I have

    - they work correctly).
    There is nothing in apache’s error_log file.
    There is a record in access_log file reading:
    192.168.10.126 - - [08/Jun/2004:16:23:32 -0700] "GET /public/testwebapp

    which gives me an impression that “proxy” – forwarding does not work.
    Where should I look for some errors?

  • DB2 Hostname Change

    Dear All,
    Our SAP Servers use Linux Suse 11 for OS with DB2 v10.1.0.2 which run on VMware virtualization on Blade Server.
    Because of that our DRC planning will be done by restoring VMware images.
    But, there are issues when we try to restore the Production servers images (seperated between PROD-CI and PROD-DB)
    On OS level, IP,  Hostname also the SAP parameters has been replaced with the new ones (named PROD-CIDR and PROD-DBDR), the issues came up when we try to change to change DB2 hostname parameter using :
        db2set -g DB2SYSTEM=[new DB2 server hostname]
    we got this error:

    Dear All,
    Finally I got the chance to give an update...
    Just yesterday, I finally succeed to replicate and configure the DR server of our QA system.
    Our steps are:
    Replicate the QA Server
    Build new server as DR server, set networking not to connect at power on
    After power on the server, I change some setting, which isChange /etc/hosts value,
                   Need to change the IP address, set the new IP and leave the hostname as it is
    Change Network Setting from YAST,
                   When we create new server from replication, they will create new connection properties (set as eth1), where the new assigned network hardware set. The old connection properties (set as eth0) contain the old IP, and will not contain hardware information/empty. So we need to delete the old connection properties and set the new IP to the new connection properties (also change the conf name from eth1 to eth0)
    Connect DR server to the network
            After this, we already can ping the DR server
    Start SAP services
    Then, the SAP DR can be accessed by SAP Logon by adding new connection while the real QA is still online.
    So far, we've tested it up to that point and haven't try to insert some transaction and also haven't check any issue related to SAP parameters.
    If there's no trouble, we intended to replicate the Production servers...
    Any inputs / suggestions about this? Is there any point that we need to check first at this point?
    Regards,
    Stan Beta
