• JBoss naming service port conflict

  - by Kramer

  I am having trouble getting JBoss started. I am running JBoss 5.1.0 on Mac OSX (yes, I know it is an old version, but that’s what the application is certified on for now). I am using Apple’s JVM 1.6.0_37. I get the following error when trying to use JBoss (there are some more exceptions, but these are the first few): Error installing to Start: name=jboss:service=Naming state=Create mode=Manual requiredState=Installed java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) at sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:218) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:383) 16:57:15,596 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/home/server/jboss-5.1.0.GA/server/myserver/conf/jboss-service.xml state=PreReal mode=Manual requiredState=Real org.jboss.deployers.spi.DeploymentException: Error deploying: jboss:service=Naming at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:118) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:46) Caused by: java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) Now I know what you are thinking, that I am running something that conflicts with that port, but I have used lsof and there is nothing listed on that port. I have tried changing the port in conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml: <bean class="org.jboss.services.binding.ServiceBindingMetadata"> <property name="serviceName">jboss:service=Naming</property> <property name="bindingName">RmiPort</property> <property name="port">5098</property> <property name="description">Socket Naming service uses to receive RMI requests from client proxies</property> </bean> Unfortunately, I then get the name errors with the new port number. I also installed a network monitoring tool on my box and it doesn't look like any ports are being opened when I start jboss, but it is possible, that the tool might be missing a port that is opened and then closed quickly. Any ideas what could be the problem or how to fix it?

• If I backup an image of my computer to a remote external hd... how would I boot from it?

  - by user29336

  I'm using Carbon Copy Cleaner on my Macbook Pro to copy my system over the air to my Windows 7 Internal 1.5TB HD. CCC is copying it as an incremental image back up. I know I can't boot from that image over the air. What I was wondering is how would I copy it onto an external HD in a bootable state? Is that possible?

• USB Wireless adapter that works with Windows 7 (32 and 64bit)

  - by Kjensen

  Can anybody recommend a USB wireless network adapter, that has Windows 7 drivers for both 32 and 64 bit? It also needs to reconnect to the network when the computer is brought out of sleep. I have three of these from earlier (from Allnet, trendnet and linksys), and just one of them has working drivers for Win7 64bit - but fail to return from sleep in a working state.

• Gentoo box can't cURL or ping after restarting net.eth1

  - by Curlybraces

  Hi all, the following is completely baffling me. We currently have a gentoo box which acts as our LAMP, DNS, DHCP server. This is assigned a static IP on the network. This server is connected directly to the internet via a BT BusinessHub Router. The server is also connected to a patch panel/switch port which connects the remaining office (around 10 PC's) to the server. Everything has been plain sailing until the other day when the server was restarted. For some reason now only portions of network accessibility is available depending on which ethernet device was last restarted. Restarting net.eth0 allows the office server to cURL, ping, etc but stops all networked PC's from accessing the internet. Then restarting net.eth1 restores all internet to the network but stops the server from curling, pinging, etc again. However, even when the server can't ping, curl, etc, I can still remote SSH and remote MySQL connect from the server command line to other external servers that we own. Here's my route map (router is 192.168.1.254): Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 eth1 Here's my /etc/conf.d/net: iface_eth0="192.168.1.99 broadcast 192.168.1.255 netmask 255.255.255.0" iface_eth1="dhcp" None of the above have ever been changed however. Things have just ceased to operate correctly, which makes me think it's a freshly added Iptables rule. Here's the Iptables Filter table: Chain INPUT (policy ACCEPT) target prot opt source destination DROP tcp -- ##.##.##.## anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:2199 ACCEPT tcp -- anywhere anywhere tcp dpt:3199 ACCEPT tcp -- ##.###.###.## anywhere tcp dpt:http ACCEPT tcp -- ###.###.##.## anywhere tcp dpt:2199 ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:http ACCEPT tcp -- ##.###.##.## anywhere tcp dpt:http ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:3128 ACCEPT udp -- ##.###.###.### anywhere udp dpt:3128 ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:http ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:https Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere ##.###.###.## DROP all -- anywhere ##.###.###.## ACCEPT all -- anywhere anywhere state NEW,ESTABLISHED Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp spt:2199 ACCEPT udp -- anywhere anywhere udp spt:4817 ACCEPT udp -- anywhere anywhere udp spt:4819 ACCEPT udp -- anywhere anywhere udp spt:3199 Help gratefully appreciated.

• VMWare Lab Manager: What's the difference between Capture to Library and Archive to Library?

  - by mcohen75

  On a configuration in my workspace I have two options, Capture to Library and Archive to Library. What's the difference between the two? The Lab Manager User's Guide isn't very useful here: Archive a Workspace Configuration to the Library You can preserve the exact state of a configuration in the configuration library. Archived configurations are read-only, but you can clone, export, and delete them. Sounds like what Capture to Workspace does.

• Would it be possible to swap system restore points on different brands of computers?

  - by P'sao

  So I have a ThinkPad computer that I've installed a program called "Deep Freeze" which restores your computer to the "Frozen" state. I also have a Toshiba computer with no Deep Freeze on it. My question is that would it be possible to creat a system restore point on my Toshiba and then replace the system volume information folder with the one on the ThinkPad so I could restore to a point with no Deep Freeze? Would this work?

• Sendmail yields "user unkown" errors even after (wrongly) setting up a catch-all account

  - by user59240

  I was trying to follow the instructions found here to set up a catch-all account, but still I get the following message for mails sent to non-existent users: The error that the other server returned was: 550 550 5.1.1 [email protected]... User unknown (state 14). Everything else works, though... /etc/mail/local-host-names and /etc/mail/virtusertable were set up as instructed. Any advice? Thanks!

• Cookieless domain alternative

  - by user63220

  I have only one folder that would benefit from a cookieless state, therefore setting up a whole subdomain for that seems a bit overkill for now, so I was wondering if deleting the cookie using mod_header in that specific folder would be enough or if it truly requires a different subdomain/domain ? For example, a .htaccess containing this in the /js subfolder of a webapp ? Header unset Set-Cookie

• how can I give openvpn clients access to a dns server (bind9) that is located on the same machine as the openvpn server

  - by lacrosse1991

  I currently have a debian server that is running an openvpn server. I also have a dns server (bind9) that I would like give allow access to by the connected openvpn clients, but I am unsure as of how to do this, I already known how to send dns options to the clients using push "dhcp-option DNS x.x.x.x" but I am just unsure how give the clients access to the dns server that is located on the same machine as the vpn server, so if anyone could point me in the right direction I would really appreciate it. Also in case this would have anything to do with adding rules to iptables, this is my current configuration for iptables # Generated by iptables-save v1.4.14 on Thu Oct 18 22:05:33 2012 *nat :PREROUTING ACCEPT [3831842:462225238] :INPUT ACCEPT [3820049:461550908] :OUTPUT ACCEPT [1885011:139487044] :POSTROUTING ACCEPT [1883834:139415168] -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE COMMIT # Completed on Thu Oct 18 22:05:33 2012 # Generated by iptables-save v1.4.14 on Thu Oct 18 22:05:33 2012 *filter :INPUT ACCEPT [45799:10669929] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [45747:10335026] :fail2ban-apache - [0:0] :fail2ban-apache-myadmin - [0:0] :fail2ban-apache-noscript - [0:0] :fail2ban-ssh - [0:0] :fail2ban-ssh-ddos - [0:0] :fail2ban-webserver-w00tw00t - [0:0] -A INPUT -p tcp -m multiport --dports 80,443 -j fail2ban-apache-myadmin -A INPUT -p tcp -m multiport --dports 80,443 -j fail2ban-webserver-w00tw00t -A INPUT -p tcp -m multiport --dports 80,443 -j fail2ban-apache-noscript -A INPUT -p tcp -m multiport --dports 80,443 -j fail2ban-apache -A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh-ddos -A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh -A INPUT -i tun+ -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT -A FORWARD -i tun+ -j ACCEPT -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT -A fail2ban-apache -j RETURN -A fail2ban-apache-myadmin -s 211.154.213.122/32 -j DROP -A fail2ban-apache-myadmin -s 201.170.229.96/32 -j DROP -A fail2ban-apache-myadmin -j RETURN -A fail2ban-apache-noscript -j RETURN -A fail2ban-ssh -s 76.9.59.66/32 -j DROP -A fail2ban-ssh -s 64.13.220.73/32 -j DROP -A fail2ban-ssh -s 203.69.139.179/32 -j DROP -A fail2ban-ssh -s 173.10.11.146/32 -j DROP -A fail2ban-ssh -j RETURN -A fail2ban-ssh-ddos -j RETURN -A fail2ban-webserver-w00tw00t -s 217.70.51.154/32 -j DROP -A fail2ban-webserver-w00tw00t -s 86.35.242.58/32 -j DROP -A fail2ban-webserver-w00tw00t -j RETURN COMMIT # Completed on Thu Oct 18 22:05:33 2012 also here is my openvpn server configuration port 1194 proto udp dev tun ca ca.crt cert server.crt key server.key dh dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt keepalive 10 120 comp-lzo user nobody group users persist-key persist-tun status /var/log/openvpn/openvpn-status.log verb 3 push "redirect-gateway def1" push "dhcp-option DNS 213.133.98.98" push "dhcp-option DNS 213.133.99.99" push "dhcp-option DNS 213.133.100.100" client-to-client

• What can an effective workflow for changing input methods be on Mac OS X?

  - by Martin Josefsson

  I switch between three languages input methods frequently, sometimes in the same typing session. The default shortcut on a Macintosh seems to be to set keyboard shortcuts for previous/next language (I hit opt-cmd-space to go to previous language) and if you're more than bi-lingual you have to cycle until you find the one for you. The ideal would be something like hitting fn-e for English, fn-j for Japanese and fn-g for German, but anything better than the current state would be a great improvement.

• i5+SSD or i7+HDD gives better performance [closed]

  - by Cas Sakal

  Which performs better for developers on a notebook(running VS.NET, SQL Server, no gaming); (A) i5 540M + SSD (Intel) or (B) i7 720M + 7200 RPM HDD (Western Digital) In short, I want to ask whether the performance difference between i5 540M and i7 720M can be compensated via using solid state drive instead of using a hard drive? Thank you, cas

• Is it possible to do "something" every time linux connects to a network?

  - by quodlibetor

  Hey, I'm trying to make a script run every time NetworkManager (or whatever, but that's what I'm talking to right now) connects to a network (or changes networks). What I really want is, metaphorically, an init directory that fires everything inside of it whenever my wifi interface changes state/essid. Or a "network status changed" runlevel. Or something.

  In which location and file does Firefox save the last windows I had opened (when Firefox crashed)? I have a complete "hot dump" copy of a file system and need to restore the state Firefox was when the system crashed, but I cannot restore the full backup itself. I can only extract the files of Firefox, but I do not know in which files I have to search for the urls that were last opened when the snapshot of the whole file system was done.

• How it was detected if last ACK lost in TCP connection termination procedure?

  - by sonali

  In TCP Connection Termination, when client enters in TIME_WAIT state means the client waits for a period of time equal to double the maximum segment life (MSL) time, to ensure the ACK it sent was received. (I read above from a book computer networking by kurose and also given in following URL http://www.tcpipguide.com/free/t_TCPConnectionTermination-2.htm ) But how it was detected if last ACK(send by client as a response to server FIN) lost?

  I've created a form in a PDF with Adobe Acrobat Pro. When empy, I want to use it as a template which the user opens, fills in, and saves as a copy to preserve the blank state of the template. Here's the trick : I found both ways to make the document read only - the user can't save the form value, only print them make the document writeable, but in this case the document acting as a template can be modified too. Any ideas? Thanks.

• Requisite of file.append

  Is it possible to make salt require that a particular file was appended to as opposed to the file merely existing? It seems like I can only require a file state. The source looks like it strips out any method names from a require attribute. In the example below, I only want the foo service to run if my lines have been appended to /etc/security/limits.conf. file.append: - name: /etc/security/limits.conf - text: - root hard nofile 65535 - root soft nofile 65535 foo: service.running: - enable: True - require: - file.append: /etc/security/limits.conf
