  • Why won't my service start, and why doesn't upstart output any errors?

    - by Alex Waters
    I am trying to 'start gunicorn' as a service via upstart as user ale. I'm using gunicorn/flask on ubuntu 12.04 w/ init (upstart 1.5) Here is my /etc/init/gunicorn.conf setuid btw setgid flask script export HOME=/home/btw export WORKON_HOME=$HOME/.virtualenvs . $HOME/.virtualenvs/default/bin/activate cd $HOME/flask workon default gunicorn -c gunicorn.py bw:app end script It doesn't output anything other than gunicorn start/running, process 12992. If i then do 'status gunicorn' I get stop/waiting. any ideas on how to debug this? I tried following http://upstart.ubuntu.com/wiki/Debugging but it didn't help. If I do the following as user ale in the app's directory: 1. workon default 2. gunicorn -c gunicorn.py bw:app then Gunicorn runs fine. Here is ~/flask/gunicorn.py: bind = "0.0.0.0:8080" workers = 3 backlog = 2048 worker_class = "gevent" debug = True daemon = False pidfile ="/tmp/gunicorn.pid" log_level = "debug" accesslog = "/var/log/gunicorn/access.log" errorlog = "/var/log/gunicorn/error.log" user = "btw" group = "flask" Also, /var/log/error.log doesn't show anything new when I try to start the Gunicorn service. If I start it manually, it shows that the workers have been loaded, etc. Thanks for any help / suggestions!

  • Alternatives to using email (in particular, Outlook) as a knowledge store?

    - by Umber Ferrule
    I suspect that, like many people, I use my work email account (accessed via Outlook 2007) to store information. I generally try to group similar things in folders and sub-folders, but with a multitude of folders this gets very unwieldy. In particular, it can be a bind to locate things using Outlook's tree structure. (As an aside: I've yet to come across a good free search add-on for Outlook.) I realise Outlook is not the best place to store all my information and I'd prefer not to. In an ideal world I'd like to be able to organise all of the information stored in Outlook in a MindMap (my software of choice being Freemind) or Wiki. To maintain an email audit-trail, I've considered saving individual emails as files using a MindMap or Wiki to link them. What do people think of this? (I can't say I relish the thought of the exporting process!) Whatever I do is going to involve some pain (i.e. setting up a Wiki/MindMap) or sticking with what Outlook provides currently. Has anyone been in the same position? Has anyone mass-migrated information from Outlook? If so, what was the best way? Any ideas or alternative proposals?

  • How should I configure my Active Directory servers so that if one goes down, users are not kicked off SQL?

    - by Matty Brown
    Today, we shut down one of our Active Directory servers during office hours to check the loading on a UPS. Since all the server did was provide Active Directory in a separate building incase the main building caught fire, or whatever, we didn't think it would have any effect on our users. Seconds after the server was shut down, we had a dozen phone calls from users experiencing this issue:- [Microsoft SQL Server Login] SQLState: '28000' [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with authentication. Once we realized what had happened, we quickly rebooted the down Active Directory server. Problem solved. But why did this happen. And what if one day a server has a breakdown and is offline for hours, or days? Shouldn't the other Active Directory servers in the domain service authentication requests without disruption to users? We have 3 Windows Server 2003 Standard servers running Active Directory as Domain Controllers with Global Catalogs, all physically located on the same network at Gigabit speeds. I believe the domain was originally Windows Server 2000, or maybe even NT 4.0. Could the issue be to down to old Group Policies inherited from these old server OS's, or some default setting in Active Directory that needs changing?

  • Test A SSH Connection from Windows commandline

    - by IguanaMinstrel
    I am looking for a way to test if a SSH server is available from a Windows host. I found this one-liner, but it requires the a Unix/Linux host: ssh -q -o "BatchMode=yes" user@host "echo 2>&1" && echo "UP" || echo "DOWN" Telnet'ing to port 22 works, but that's not really scriptable. I have also played around with Plink, but I haven't found a way to get the functionality of the one-liner above. Does anyone know Plink enough to make this work? Are there any other windows based tools that would work? Please note that the SSH servers in question are behind a corporate firewall and are NOT internet accessible. Arrrg.

  • hosts file seems to be ignored

    - by z4y4ts
    I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.mydomain.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

  • How to subnet hosted VMs

    - by bwizzy
    I have a network of VMs each having a LAN IP address and a public IP address. They each have a 1:1 NAT map for public access via the public IP for HTTP, SSH etc. I'm trying to figure out a way to restrict the LAN IPs from talking to each other, but there are some cases where a group of LAN IPs will need to communicate. I'm using pfSense as a firewall / router on a 192.168.0.0/24 configuration. It seems like I could assign each VM it's own subnet and add a static route to the firewall for that VM to get back to the firewall for internet access / other fw rules. Is that right? I assigned 1 VM with: address 192.168.1.2 netmask 255.255.255.254 gateway 192.168.1.1 Then added a static route on the FW's LAN interface using 192.168.1.0/30 as the destination network and 192.168.1.1 as the gateway. Nothing appears to be working, anyone have any ideas? Please be aware I'm not that familiar with subnets. Thanks!

  • How can I make the Windows 7 taskbar behave like a cross between the old Quick Launch and new Superbar?

    - by frumious
    I really like the taskbar in Windows 7, I think combining buttons to launch apps and the icons that show your running apps is groovy. However, because I like having as much space as possible, I've got small icons enabled and shrunk the bar down to one row. I've also told it not to group the running apps unless there's no space left (to save me having to work harder to find the particular window I want), which also means that they have captions, and are thus quite wide. The (admittedly small) problem this gives me is that I can pin all my favourite apps to the bar, which looks much like the old Quick Launch bar, but when I launch them the running apps because much wider, and the unlaunched apps get lost amongst them. I can manually change the order to fix this, but next time I'll launch a different app and I'll be back to square one. What I'd prefer is for small unlaunched icons to be kept on the left, and wider running apps to move over to the right, which for me would be the best of both worlds. Is there any way I can organise that? I'm aware that one can use the traditional quick launch bar in Windows 7, but that's not what I'm after; I generally prefer the Windows 7 way.

  • SQL Server 2008 Cluster Installation - First network name always fails

    - by boflynn
    I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

  • Ubuntu Pound Reverse Proxy Load Balancing Based off active server load?

    - by Andrew
    I have Pound installed on a loadbalancer. It seems to work okay, except that it randomly assigns the backend server to forward the request to. I've put 1 backend machine under so much load that it went into using swap, and I can't even ssh into it to test this scenareo. I would like the loadbalancer to realize that the machine is overloaded, and send it to a different backend machine. However it doesn't. I've read the man page and it seems like the directive "DynScale 1" is what would monitor this, but it still redirects to the overloaded server. I've also put in "HAport 22" to the backend figuring since I can't ssh in, neither could the loadbalancer and it would consider the backend server dead until it gets rid of the load and responds, but that didn't help either. If anyone could help with this, I'd appreciate it. My current config is below. ###################################################################### ## global options: User "www-data" Group "www-data" #RootJail "/chroot/pound" ## Logging: (goes to syslog by default) ## 0 no logging ## 1 normal ## 2 extended ## 3 Apache-style (common log format) LogLevel 3 ## check backend every X secs: Alive 5 DynScale 1 Client 1200 TimeOut 1500 # poundctl control socket Control "/var/run/pound/poundctl.socket" ###################################################################### ## listen, redirect and ... to: ## redirect all requests on port 80 to SSL ListenHTTP Address 192.168.1.XX Port 80 Service Redirect "https://xxx.com/" End End ListenHTTPS Address 192.168.1.XX Port 443 Cert "/files/www.xxx.com.pem" Service BackEnd Address 192.168.1.1 Port 80 HAport 22 End BackEnd Address 192.168.1.2 Port 80 HAport 22 End End End

  • Xen domU passwd file overwritten with console log output

    - by malfy
    I was setting up a Debian Xen domU and after booting it fine, I added basic configuration to /etc/network/interfaces and ran /etc/init.d/networking restart. This failed so I decided to reboot.

  • HAProxy is caching the forwarding?

    - by shadow_of__soul
    i'm trying to set up a server structure for an application i'm building in Node.js with socket.io. My setup is: HAProxy frontend forward to -> apache2 as default backend (or nginx, is apache in this local test) -> node.js app if the url has socket.io in the request AND a domain name i have something like: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 user haproxy group haproxy daemon defaults log global mode http maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 frontend all 0.0.0.0:80 timeout client 5000 default_backend www_backend acl is_soio url_dom(host) -i socket.io #if the request contains socket.io acl is_chat hdr_dom(host) -i chaturl #if the request comes from chaturl.com use_backend chat_backend if is_chat is_soio backend www_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout server 5000 timeout connect 4000 server server1 localhost:6060 weight 1 maxconn 1024 check #forwards to apache2 backend chat_backend balance roundrobin option forwardfor # This sets X-Forwarded-For timeout queue 50000 timeout server 50000 timeout connect 50000 server server1 localhost:5558 weight 1 maxconn 1024 check #forward to node.js app The problem comes when i made a request to something like www.chaturl.com/index.html it load perfectly but fails to loads the socket.io files (www.chaturl.com/socket.io/socket.io.js) why it redirect to apache (and should redirect to the node.js app that serve the files). The weird thing is that if i access directly to the socket.io file, after refreshing a few times, it loads, so i suppose is "caching" the forwarding for the client when it makes the first request and reach the apache server. Any suggestion of how this can be solved? or what i can try or look about this?

  • RPM issues after signing JDK 1.6 64-bit

    I'm trying to sign the Java JDK 1.6u21 64-bit RPM on CentOS 5.5 for use with Spacewalk and I'm running into problems.

  • "Server Unavailable" and removed permissions on .NET sites after Windows Update [closed]

    - by andrewcameron
    Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.

  • Problem with Windows Service and network printers.

    - by Mohammadreza
    I have a Windows Service application that every now and then should print some documents. As far as I know, to print those documents, my service must be run with a user account other than Local Service or Network Service. So i have created a user account and added that to the Administrators group and ran the service with it. With locally installed printers, I don't have any problems because those printers are automatically installed for all accounts. To be able to print with the network printers, I have created another application that syncs the installed printers of the currently logged in user with the user account that my service uses with the rundll32.exe printui.dll,PrintUIEntry command. In Vista and Windows7 I don't have any problems with the syncing of the printers because every time that a printer should be installed the authentication window will open and it asks for the appropriate user account to install that printer (The service user account is not created on the network printers computers) but in XP a find dialog with the "Connecting to {printername}" caption will appear and stops responding, or sometimes it installs the printer but every time service tries to print, a Win32Exception with "A StartDocPrinter call was not issued" message will throw and in the user account that runs the sync application a duplicate printer will be shown and I couldn't delete those printers unless with force (using registry). Am I doing the right thing for printing documents with Windows Services at all? If yes, how can I solve the above-mentioned problem? And if not, what the heck should I do? Thanks.

  • Fixed and dynamic IPs in ISC DHPD lead to double lease

    - by GorillaPatch
    I would like to have a small dynamic adress part and the most clients are assigned a fixed IP adress. My dhcpd.conf looks like this: use-host-decl-names on; authoritative; allow client-updates; ddns-updates on; # Einstellungen fuer DHCP leases default-lease-time 3600; max-lease-time 86400; lease-file-name "/var/lib/dhcpd/dhcpd.leases"; subnet 192.168.11.0 netmask 255.255.255.0 { ddns-updates on; pool { # IP range which will be assigned statically range 192.168.11.1 192.168.11.240; deny all clients; } pool { # small dynamic range range 192.168.11.241 192.168.11.254; # used for temporary devices } } group { host pc1 { hardware ethernet xx:xx:xx:xx:xx:xx; fixed-address 192.168.11.11; } } The motivation for the pool declaration with deny all hosts comes from the ISC DHCPD homepage http://www.isc.org/files/auth.html This will allow hosts to be first added to the network, where they will receive a temporary IP from the 241-254 adress range and then later write an explicit host declaration. Upon next connect it will receive the right configuration. The problem is that I am getting error messages that 192.168.11.13 has a dynamic and a static lease. I am a bit confused as I expected the pool declaration with deny all clients would not count as dynamic. Dynamic and static leases present for 192.168.11.13. Remove host declaration pc1 or remove 192.168.11.13 from the dynamic address pool for 192.168.11.0/24 Is there a way to have the DHCP server send an DHCPNA to clients if they have a host statement and retain this dynamic range?

  • Websockets Server with Fault-Tolerance and Durable Message Store

    - by smitchell360
    I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for. EDIT So, after some research the following installed options seem to be the most robust: Kaazing Migratory Migratory (http://migratory.ro) Hosted services that seem "real" Pusher (great API but no history feature yet) PubNub (has history) All of the above services have graceful fallback to other communication methods if websockets are not available. I was not able to find any open source that provided "out of the box" clustering, fail-over, and a durable message store to play back history. There are some projects that may serve as good starting points, but not exactly what I am looking for.

  • Suspected brute force attack

    - by HarveySaayman
    Recently I acquired a dedicated server from a local ISP to play around with. As the tags suggest, its a windows server 2008 R2 machine. I've only had it for a few days, and no real traffic is going to it yet. I haven't even deployed a "real" website to it yet. Just a silly page so that I could check IIS, my host headers, DNS records, etc are all configured correctly. While playing around, I noticed a ton of Audit Failure entries in the event viewers security logs. It seems something is trying to access the administrator account, and failing. It smells like a brute force attack to me. My ISP gave me the account details of the administrator account and I used those to RDP into the box, which I've heard is not the securest of situations. I created myself another account and added myself to the administrator group, so im using that account to gain acceess to the machine now. In response to all of this i used http://strongpasswordgenerator.com/ to generate me some 20 character length strong passwords and changed all of my account passwords, even the SQL sa user. I also enabled the auto ban feature of FileZillaServer (my FTP server) My questions: 1) how can i detect this kind of thing better? 2) how can i protect my server from unauthorized access better? PS: I'm a software dev, not a sysadmin so please mind my server security idiot-ness-ness

  • eAccelerator Issue - Cache Directory Empty.

    - by Tom
    Hi all, Hoping someone can give me a hand with this. I've recently installated eAccelerator 0.9.6.1 - On a CentOS LAMP server. Had it working fine, using the /tmp/accelerator as the cache directory. php.ini set up: zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so" eaccelerator.shm_size="200" eaccelerator.cache_dir="/var/cache/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="3600" eaccelerator.shm_prune_period="180" eaccelerator.shm_only="1" eaccelerator.compress="1" eaccelerator.compress_level="9" php -v output: PHP 5.2.12 (cli) (built: Feb 3 2010 00:34:28) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies with eAccelerator v0.9.6.1, Copyright (c) 2004-2010 eAccelerator, by eAccelerator with the ionCube PHP Loader v3.3.20, Copyright (c) 2002-2010, by ionCube Ltd. I had to remove the cache directory as I was testing something. Remade it, re-set permissions and found that eAccelerator was no longer creating cache files within the folder. I thought it might be down to ownership rights on the folder so chown'd it apache.apache and this made no difference. I recreated the directory in /var/cache instead and editted php.ini to point to the new cache dir location, chmod'd, chown'd etc. and still eAccelerator is not creating any of the cache files in the directory (just empty). Could someone suggest what I might be doing incorrectly here. I've read through numerous pages to try and troubleshoot the issue to no avail. Any help appreciated.

  • Permission issue for apache

    - by Aamir Adnan
    Environment Details: Amazon Ec2 Ubuntu 12.04 Django + mod_wsgi + python 2.6 web server: apache2 I have mounted a 10GB ebs volume to an instance to /mnt/ebs1/. After mounting the volume and formatting, I have placed all my project files in /mnt/ebs1/project. the wsgi file is in /mnt/ebs1/project/apache/django.wsgi. The content of wsgi file is: import os, sys sys.path.insert(0, '/mnt/ebs1/project') sys.path.insert(1, '/mnt/ebs1') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.common.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() My httpd.conf file looks as: LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so WSGIPythonHome /usr/bin/python2.6 WSGIScriptAlias / /mnt/ebs1/project/apache/django.wsgi <Directory /mnt/ebs1/project> Order allow,deny Allow from all </Directory> <Directory /mnt/ebs1/project/apache> Order allow,deny Allow from all </Directory> Alias /static/ /mnt/ebs1/project/static/ <Directory /mnt/ebs1/project/static> Order deny,allow Allow from all </Directory> The above configurations gives me Forbidden: You don't have permission to access / on this server. I tried to find the user which is running apache using ps aux which is www-data and has group www-data. I have tried to change the ownership of /mnt/ebs1 and its subdirectories using chown -R www-data:www-data /mnt/ebs1 but that still does not solve the problem. Can any one tell me what I am doing wrong or have missed?

  • Per connection bandwidth limit

    - by Kyr
    Apparently, our server box running Windows Server 2008 R2 has a per connection bandwidth limit of 0.2 MB/s. Meaning, while one TCP connection can pull at max 0.2 MB/s, 60 parallel connections can pull 12 MB/s. We first noticed this when trying to checkout large SVN repository from this server. I used a simple Java application to test this, transferring data from server to workstation using variable number of threads (one connection per thread). Server part of the application simply writes 1 MB memory buffer to socket 100 times, so there is no disk involvement. Each connection topped at 0.2 MB/s. Same per connection limit was for only one as was for 60 parallel connections. The problem is that I have no idea from where this limit comes from. I have very little experience administrating Windows Server, so I was mostly trying to find something by googling. I have checked the following: Local Computer Policy QoS Packet Scheduler Limit reservable bandwidth: it's Not configured; Group Policy Management Console: we have two GOPs, but neiher has any Policy-based QoS defined; There isn't any bandwidth limiter program installed, as far as I can tell. We're using standard Windows Firewall. I can update this question with any additional information if needed.

  • Exchange MSExchangeIS Mailbox Store Error

    - by Bart Silverstrim
    Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.

  • Connecting jconsole using SOCKS to Amazon EC2

    - by freshfunk
    I'm trying to use jconsole to view stats on an EC2 instance by using a socks proxy created by SSH. I've tried the various scripts mentioned in the links below but to no avail: http://simplygenius.com/2010/08/jconsole-via-socks-ssh-tunnel.html http://gabrielcain.com/blog/2010/11/02/using-ssh-proxying-to-connect-jconsole-to-remote-cassandra-instances/ I'm running ssh -f -ND 8123 myuser@mymachine and verified that at least Firefox goes through it as a proxy. I then run jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort=8123 service:jmx:rmi:///jndi/rmi://ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com:8080/jmxrmi I run netstat -n on my EC2 instance and I see a connection created by my machine. However, the connection eventually disappears and I get a 'channel 2: open failed: connect failed: Operation timed out' from my ssh tunnel. I've opened the jmx port through the security group and I've checked the port on the EC2 instance to make sure it's open (by telnet-ing to it). I'm not sure where to look next. Are there some properties in sshd_config or ssh_config I need to enable for tunneling? Or anything in Mac OS X? I feel like a serious noob but sys administration is really not my strong point. I've spent several hours and can't get this to work.
