ubuntu - Port is listening but cannot connect from remote





I have a catalyst server running on a VM.



[info] Hello powered by Catalyst 5.90103                                                                                                                                             
HTTP::Server::PSGI: Accepting connections at http://0:3009/



And connecting within the VM



vagrant@precise32:/var/log/apache2$ curl 'http://localhost:3009'
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
etc ...


The port seems to be listening



vagrant@precise32:/var/log/apache2$ netstat -an | grep "LISTEN "

tcp        0      0 0.0.0.0:36300           0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:3009            0.0.0.0:*               LISTEN


Connecting remotely I can see port 80 but not 3009



curl 'http://localhost:80'

curl: (52) Empty reply from server
curl 'http://localhost:3009'
curl: (7) Failed to connect to localhost port 3009: Connection refused


I've seen similar threads but nothing has helped. This is iptables



vagrant@precise32:/var/log/apache2$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     all  --  anywhere             anywhere             ctstate RELATED,ESTABLISHED

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination



And the firewall is turned off



vagrant@precise32:/var/log/apache2$ sudo ufw status  
Status: inactive


I'm very new at VM, I'm not sure if this is a hosts problem, an apache problem or a cataylst problem. I did try running a python server and couldn't connect to that either. All advice is much appreciated. Thanks



EDIT - I've looked at similar posts, the general solutions there are not listening ports or firewall. I don't think either applies here.



Answer



You are trying to access the app on vagrant box listening on port 3009, using address localhost remotely. For this to work, you need to setup the port forwarding correctly as mentioned in the vagrant doc: https://docs.vagrantup.com/v2/getting-started/networking.html



Check and make sure, it is setup correctly and that the request on http://localhost:3009 is forwarded to the vagrant box. You should also make sure that your local firewall is not blocking connection to the port.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
