• How can I connect JConsole to WebLogic using the WL SSL Listen Port

  - by Mircea Vutcovici

  I would like to be able to use JConsole on remote WebLogic servers via the multiplexer port on SSL. Is it possible this without doing any configuration changes WebLogic? Only by adding some jars (e.g. wljmxclient.jar) or parameters to JConsole. I've tried with variations of the following command without success: $JAVA_HOME/bin/jconsole -J-Djava.class.path=$JAVA_HOME/lib/jconsole.jar:\ $JAVA_HOME/lib/tools.jar:$WL_HOME/server/lib/wljmxclient.jar \ -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote -debug \ service:jmx:rmi:///jndi/iiop://server_name:7441/jmxrmi I think that one of the problem is that the SSL is not enabled in JConsole.

• Which tools should I use to work efficiently on a remote server?

  - by Konstantin

  I rented a virtual ubuntu server and am trying to setup a web application. I am working from ubuntu. I know how to use the command line, but it is slow and as a visual person, I prefer graphical interfaces. So I connected with nautilus via ssh and was now able to browse the directories graphically. But my permissions are just those of "other", so I cannot do much without o+rwx. What tools do you use to do setup and administrate your servers? Should I write code locally rather then directly on the server and rsync it? EDIT: It is NOT a production server, I am simply fiddling around there.

• Fortigate - Accessing a Virtual Server address from several interfaces

  - by Jeremy G

  I am setting up a new application in its own DMZ on our Fortigate 300C firewalls. I have defined a load-balancing configuration for part of the application, and this works fine for traffic coming in from our internal network. However, I would also like this application to be reachable from other DMZs, for inter-application traffic, and from the SSL VPN interface. I can't seem to define the required policy, and it seems this is due to Virtual Servers being bound to the client interface on the Fortigate rather than the server interface (and so my virtual IP is not accessible from any of these other interfaces) Does anyone have an idea how I might go about this ? I guess I could create other virtual IPs for each interface, but this gets complicated to handle as clients need to change the address they use depending on how they are connecting. Thanks, Jeremy G

• pcap stream rotation and pruning

  - by pilcrow

  Some of my servers collect a lot of packet data. Is there a utility (or patch to tcpdump(1)) to log a pcap stream to disk which: Rotates based on size of data written Prunes written files, keeping only the N most recent Does not re-use output filenames Is self-contained (Ruling out, e.g., a rotation with external pruning via crond(8)+tmpwatch(8)) Basically I want a multilog or svlogd that groks the pcap record format. The -W filecount option of tcpdump-4.0.0 "prunes" by recycling old filenames, which violates #3 above, forcing me to consult mtimes to determine recency and providing no guarantees against surprise truncation of the log file. The -G option introduces strftime(2)-specifier support in output filenames, which would give me at least second-precision in file names, but I can't figure out how to get pruning to work with this scheme.

• Debug Apache mod_status showing 151 requests/sec - 2.7 GB/second

  - by James Hackett

  One of my web servers went crazy this morning and showed "151 requests/sec - 2.7 GB/second - 140.7 MB/request" the normal is like "11.1 requests/sec - 65.6 kB/second - 5.9 kB/request" I don't even think that kind of through put is possible on my server.

• Why does RDP Licensing is licensing the same device multiple times? [closed]

  - by NeerPatel

  Possible Duplicate: Can you help me with my software licensing issue? I've got a Citrix XenApp 6.5 Farm running on Win 2008 R2 Servers. I purchased 300 Device RDP/Remote App Licenses for ~200 users. We went with Device licenses, because most of the end users use the same machines. After 1 month of operating, we started to run out of licenses. It turns out the licensing service is consuming multiple licenses for the same machine. I can revoke licenses, but there is a limit to how many I can do. Is this operating correctly? The only explanation I can come up with is that the Licensing service is giving a license to a device for every server it connects to in our Citrix farm.

• Unable to connect to Adobe Connect

  - by ub3rst4r

  I am having troubles trying to connect my colleges Adobe Connect. I have done the test meeting connection and it will say "Unable to connect". I have tried connecting on 3 other computers and it works with flying colors. I am running Norton 360 on my computer and I also tried it on my other laptop thats also running Norton 360 and it works on that laptop. I also checked my hosts file and that is not the problem because I am able to connect to the server (on port 80) but not the Adobe Connect port (port 1935). The only thing in it is "127.0.0.1 localhost" Here are the details from the log that the test created: Player Version: WIN 11,3,300,271 App-Server returned: code:ok, servers=rtmp://connect.bowvalleycollege.ca:1935/_rtmp://localhost:8506/,rtmpt://connect.bowvalleycollege.ca:443/_rtmp://localhost:8506/ ERROR: FMS Server did not return correctly!

• Amazon ec2 - WildCard Sub-Domain

  - by Sharanc25

  I'm running an ec2 instance on ubuntu running lamp stack. I configured my httpd.conf file to support wildcard sub-domain but it didn't work. My httpd.conf file NameVirtualHost * <VirtualHost *> DocumentRoot /www/example ServerName example.com ServerAlias *.example.com </VirtualHost> I tried all possible solutions but they didn't work. Finally I used amazon Route-53 to setup a wildcard DNS to redirect all *.example.com to example.com. My question is, Is it okay if I use Route-53 instead of httpd.conf file for wildcard Sub-Domain ? Is there an error in my httpd.conf file ? (Note: I used the same httpd.conf settings with another hosting provider and it worked perfectly there.) Additional Information : VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:80 is a NameVirtualHost default server example.com (/etc/apache2/httpd.conf:1) port 80 namevhost example.com (/etc/apache2/httpd.conf:1) port 80 namevhost ip-xx-xxx-xx-xxx.ec2.internal (/etc/apache2/sites-enabled/000-default:1) Syntax OK

• Easy Server Monitoring/Logging point in time solution?

  - by Andre Jay Marcelo-Tanner

  I managed my company's servers and I need to know if load spiked at 3am on the web or mysql server, what processes were active in apache or what queries were going on in mysql at that point in time and maybe any other information that will help me. I know all of that is in log files all over and its literally a PITA to look it all up and correlate data. isnt there 1 solution thats been invented. i know we have pingdom to monitor uptime and responsiveness. like if it has taken 30 seconds to load a page or an error was given by apache or php or mysql to the browser, i want to know that and what mysql processes were running at the time, the apache full status and maybe top output also. stuff like that also would be looking for a SAAS like cloudkick, something i dont have to spend an entire month of work hours setting up when we can pay for something cheaper.

• Checkpoint FW-1disk full

  - by krugger

  Hi, The logging filled the disk of the managment node. This cause the firewall nodes to start logging locally. After deleting some old logs, restarting the managment node logging is still being done locally at the firewall nodes. I have already done a fw fetchlogs on all firewall nodes to get the local log entries. How can I tell the firewall nodes that they should once again connect to the managment node? My syslog_servers show doesn't show any syslog servers. But the documentation mentions that this is for additional logging and not for logging between firewall nodes and the managment node.

• Linux memory fragmentation

  - by Raghu

  Hi all, Is there a way to detect memory fragmentation on linux ? This is because on some long running servers I have noticed performance degradation and only after I restart process I see better performance. I noticed it more when using linux huge page support -- are huge pages in linux more prone to fragmentation ? I have looked at /proc/buddyinfo in particular. I want to know whether there are any better ways(not just CLI commands per se, any program or theoretical background would do) to look at it.

• Welcome files are not loaded! Need help with Railo, mappings and J2EE configuration!

  - by mrt181

  I have installed a J2EE Server (tried it with Glassfish3, Tomcat6 and Resin4) on Win7 64bit and deployed Railo3.1. I have then added a virtual host to the J2EE server, i.e. Resin: <host host-name="railo"> C:/resin/webapps/railo In the Railo Admin i have added this mapping: Virtual Physical / C:/webapps/ When i access http://railo:8080/ my index.cfm welcome file in C:/webapps/ is loaded (index.cfm is definded in Railos web.xml). When i try to access http://railo:8080/test which contains the same index.cfm i get an 500 Servlet Exception java.io.FileNotFoundException: C:\webapps\test (access denied) (on all J2EE Servers i tried so far). http://railo:8080/test/index.cfm works fine. I already tried to add index.cfm to Resins welcome-file-list in app-default.xml to no avail. I want to be able to access deployed apps without this url: http://localhost:8080/app/ Instead i want to use this: http://app:8080/

• Problem closing MDI child window in Terminal Services/Remote Desktop Connection 7.0

  - by Justin Love

  I have one user whose computer just got updated to the 7.0 Remote Desktop Connection. Concurrently, she has started having a problem closing the MDI child windows in an old FoxPro application running on the remote server. We have two different servers, both 2003, running the same application, one locally and one at a remote office. Only the remote office server is giving trouble. It works fine for me, even when logging into her TS account. No other users have complained. The other day the same user experienced an error message (path not found for a path showing a localization placeholder) starting the RDC, fixed by reboot. I suspect she may have had RDC running during the 7.0 upgrade.

• cpanel api fileman alternative

  - by Coombesy

  trying to remotely unpack a zip file, then move the contents on cpanel servers. Some research led me to xmlApi class and the fileman module. And here my problem lies as Fileman module is returning html based on the cpanel theme (which we won't know) - and all I need is a list of files. here is the code flow: * using ftp, the zip is uploaded * using Fileman module unpack zip * loop through unpacked files and move here is my call to list the files: $files_html = $xml->api1_query($user, "Fileman", "listfiles", array( "{$ftp_dir}", //source dir 0 //chooser )); and it is returning the html for the filemanager - which is going to be different based on the cpanel theme. Surely their has to be another way to simply just list the files in that directory? any help would be appreciated, been researching this for past day and can't find solution anywhere. cheers ;)

I have tried using public dns servers from Google but with still no results. I've restarted my router with no results. All other devices on my network are having no trouble at all. I've tried updating the wireless driver but the manufacturers website claims that the Win8.1 driver should be updated with the update from windows. So i cant find a wireless driver... Anyone else having this error and does anyone have any ideas on how to fix it??

• Best Solution for Load Balancing NFS File Access?

  - by DairyKnight

  I'm trying to find an optimum solution for accessing the NFS file share in my company. We have a central file server in North America and has 30GB~50GB of updated data everyday. And it's very slow for our Europe and Asia branches to access directly. Therefore, I'm trying to setup two replicate servers in those continents. I'm currently using rsync, but wonder if there exists a better solution acts more like a distributed RAID, which allows the user to transparently access the file whether synced or not. And user request will be dispatched to remote server if the file is not yet synced. I'm now looking into DRBD, but it seems not to have the functionality of auto-dispatching requests. Does anyone know if there's a better solution?

• Apache error_log showing which command output

  - by Unai Rodriguez

  Apache's error_log shows lines like the following: --- snip --- which: no ruby in (/sbin:/usr/sbin:/bin:/usr/bin) which: no locate in (/sbin:/usr/sbin:/bin:/usr/bin) which: no suidperl in (/sbin:/usr/sbin:/bin:/usr/bin) which: no get in (/sbin:/usr/sbin:/bin:/usr/bin) which: no fetch in (/sbin:/usr/sbin:/bin:/usr/bin) which: no links in (/sbin:/usr/sbin:/bin:/usr/bin) which: no lynx in (/sbin:/usr/sbin:/bin:/usr/bin) which: no lwp-mirror in (/sbin:/usr/sbin:/bin:/usr/bin) which: no lwp-download in (/sbin:/usr/sbin:/bin:/usr/bin) which: no kav in (/sbin:/usr/sbin:/bin:/usr/bin) --- end --- The architecture is: Internet - Load Balancer - Varnish - Apache There are several web servers behind the load balancer and I have checked at least one of them with rkhunter (link) and couldn't find anything suspicious. Versions: CentOS 5.7 Varnish 2.1.5 Apache 2.2.3 PHP 5.2.17 Does this mean that someone has executed the command which through Apache? How can that happen? Thank you so much.

• Software for failover across multiple external hosts

  - by Lin

  I have multiple webservers with the same content, hosted across different providers. However, I can't seem to find a nice, simple failover solution. Load-balancing software (Pound, HAProxy, etc.) are unnecessary, and I need the flexibility to manage over 100+ domains, so the paid DNS failover solutions I've found are too expensive. So far the simplest solution I've thought of is just to set a very low TTL (30min - 1hr) in each zone entry on my nameservers (running BIND). Then, continuously monitor each server, and temporarily remove failed servers from zone entries. But this seems like something that should be currently available. I only have root access to different VPSes running CentOS. Any suggestions? Thanks!

• FTPS SSH Host Key after IP Address Change

  - by David George

  I have a Secure FTP (FTPS) server that my remote sites to upload files to daily via scripted routines that run. I have had issues in the past when upgrading hardware and deploying new servers causing the RSA Fingerprint to change for that server. Then all my remote sites can't connect until I have the old key removed (usually via ssh_keygen -r myserver.com). I now have to change the IP address for myserver.com and I wondered if there is anyway to proactively generate new host keys so that when the server address changes all my FTPS client remote sites don't break?

• Windows 2008 Group Policy Setting? - Migration Headache

  - by DevNULL

  I have a small domain of users that I just migrated from a linux domain running open-ldap. Our new servers are running Windows 2008 Standard. I've installed Active Directory and everything is working perfectly... except that the initial user privileges is pretty restrictive and I need to loosen it up a bit. For example once they login to their workstations, they can create new files and folders but can not modify existing files or start. I basically want to open it all up except for software installations. Can someone please help with with this migration headache?

• How can I tell which interface my Supemicro IPMI is piggybacking on?

  - by lorin

  I've used IPMI before, but only on servers where the IPMI interface had a dedicated ethernet port. I've got an Ubuntu 10.04 server with two ethernet cards, which is supposed to have an IPMI interface on it (the motherboard is a Supermicro H8DMR-I2). From what I understand, the IPMI interface is piggybacking on one of the two NICs. Is there any way I can tell which NIC the IPMI interface is piggybacking on? Using ipmitool I've tried to set the IP address on the IPMI interface for the subnet for eth0, and then the subnet for eth1, and it's never reachable. (Can you even reach an IPMI interface from the same NIC it's piggybacking off of, or do you need to try connecting from a different machine on the network?) Also, is there anything special I need to do to enable it? I can access the IPMI interface locally using "ipmitool".

• ForwardAgent in Jenkins

  - by r_2

  I'm trying to enable ForwardAgent in the "Publish over SSH" Jenkins Plugin. This would allow jenkins to execute deployments, rsyncs and svn+ssh checkouts on remote servers. But there's no option for this in the GUI. ForwardAgent is set to yes in /etc/ssh/ssh_config and in /var/lib/jenkins/.ssh/config, but when Jenkins jobs login over ssh, the remote session does not have the key loaded in agent. ("Could not open a connection to your authentication agent.") Is there a way to force ForwardAgent, or a better way to do this (via a Jenkins slave)? Thanks for any ideas, much appreciated!

• Nagios orphaned services warnings

  - by Gordon

  We have had Nagios running on one of our servers with out any problems for a while but lately certain old service warning have been reappearing and then disappearing on the service detail page. From looking at the logs I found warning like the following. Warning: The check of service 'Tomcat' on host 'virtual1' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the service... Has anyone ever came across this before or at least know a way to delete the old Orphaned Warnings. The Nagios Version we are running is Version 3.0b7 so an update might be in order. Thanks.

• HAProxy authenticated httpchk (health check)

  - by Markel

  I am using HAProxy on EC2 and using httpchk to manage node availability. I had used a pseudo-unique path as the health check route in an attempt to make sure only my servers responded to the health check. Earlier today I had an EC2 server fall out of existence, and before the haproxy config was auto-regenerated (controller issues), Amazon had reassigned the IP to someone whom 200's every request (honeypot?), my HAProxy host then pulled the server back into rotation and started distributing some of my traffic there until the controller recovered and removed the ip from the list. TLDR; Is there a way to add a server authentication method to HAProxy's httpchk?
