[solved] I Can´t manage Sabnzbd+ from my home after rebooting

Post by sadnem »

Hi, my issue is that after rebooting i can´t access sabnzbd+ from my home, i´ve tried restarting the /etc/ini.d/sabnzbd+ script several times but it´s still not working, I´m accesing to sabnzbd+ via my.server.ip:port/sabnzbd/ but ff says something like: "The connection timed out" and i don´t know anymore what to do, Any idea?
PS: I know that sabnzbd+ is working because files are being downloaded (i have some rss feeds configured so sab download automatically).

Which OS are you using exactly? All Ubuntu? On the client too?
Are you trying to access SABnbzd through / behind a NAT device (router/modem)?
On which (local?) IP address is your SAB machine? Use "ifconfig" to get that information. Has the IP address change due to the reboot?
Can you access SAB from another computer on the same LAN?

Re: I Can´t manage Sabnzbd+ from my home after rebooting

- I´m using Ubuntu on the server and Winxp on the client
- I don´t think so because before the reboot i could use sab perfectly (in addition, i can tell you that i´m using another apps that require the use of ports and they are running fine)
-  The IP adress have not changed because its static.
- If you refer to my lan no, i can´t but if you refer to the server LAN i can´t tell you because the only way i have to access it is through ssh.

Thanks for the support.
Regards, Sadnem.
EDIT: SOme more info (maybe it help) I´ve tried changing the ports to but it´s not working.

Sorry, I'm lost: there is a LAN, there is a server LAN, there is no NAT, and there is only ssh access?

Maybe you can make a drawing and post it here? Please include IP addresses (from ifconfig) in the drawing.

BTW: have you considered using IPv6? Both on Ubuntu and Windows it's easy to use.

I think that you said it correctly although im not sure if theres no NAT :S.

I have ipv6 correctly configured on Ubuntu, but nothing on WinXP No problem for me using it but i have no idea how to do it, it would be very much apreciated if you can help me.

Looks like a remote (virtual, rented) server, so much for the lan or not confusion. Try to find out if and where sab is listening for connections, for example using sudo netstat -ntepl on the server side. You're looking for a python process, with the port of the local address matching that of sabnzbd.

There's a public IP address on your server, so indeed there's (probably) no NAT.

However, port 8080 is taken by the ISP / hosting provider. So on which port is your SABnbzd running?
Maybe SABnzbd is indeed running on port 8080, which port is overruled by your ISP. If so, try port 8888 or so.

Use the command from the previous post to find out. Here's mine, with SABnzbd on port 8080:

Code: Select all

Re: I Can´t manage Sabnzbd+ from my home after rebooting

Post by sadnem »

yes, i´ve changed the port of sabnzbd to 26789:

Code: Select all

sudo netstat -ntepl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode       PID/Program name
tcp        0      0 212.227.54.53:26789     0.0.0.0:*               LISTEN      0          288091      31975/python
more entries but none of them listens to the same port...
But i had configured sabnzbd+ to listen on this port before, i mean it wasn´t listening to 8080from the begining so it´s not working, :S

Maybe fail2ban or some other service is blocking the access to sabnzbd?

All this shows sab running correctly, but behind a firewall. An nmap scan from my end shows 26789/tcp as filtered. sudo iptables -L -n -v server side might help you remember, otherwise start talking to the hosting provider...

^^^ This is where the attempts to connect to the web interface will end up. Unfortunately, the relevant part of the firewall (PUB_IN target) isn't posted, but I'd expect it to be a list of services that are accepted, followed by a catch-all DROP for anything else. If so, you should modify the firewall configuration to allow stuff on sab's port too.

As I expected, PUB_IN defines public services and denies anything else (note that PAROLE also means it's allowed since that chain doesn't really do anything). Can't tell you where your firewall config is, afaik Ubuntu doesn't have a firewall by default so you'll have had to activate it yourself. sudo iptables -A PUB_IN -p tcp --dport 26789 -j ACCEPT probably works as a quick fix, but will be lost on every boot. Anyway, this is going quite far off-topic so please ask any further questions in some Ubuntu support forum rather than here.
