Oct 20, 2015I have installed Debian Jessie (<-- brilliant OS ) on my uncles Laptop (it is a Thinkpad E540) with Cinnamon as desktop environment. The installation was no problem. Everything apart from one minor thing works nicely. The minor thing however is the following:
I don't know what it is, but when I don't use a particular usb port for a while and then try to plug in a usb stick or a wacom tablet, it doesn't get recognized, it doesn't show up when I use f.e. Code: Select alllsusb. When I close the lid of the laptop and open it again, then the particular usb device gets recognized and cinnamon asks me what to do, f.e. open a folder and show the content of the usb stick I have plugged in. Because of the success on two other laptops I use the following
Code: Select all# /etc/systemd/system/powertop.service
[Unit]
Description=Powertop tunings
[Service]
Type=oneshot
RemainAfterExit=no
ExecStart=/usr/sbin/powertop --auto-tune
Environment="TERM=xterm"
[Install]
WantedBy=multi-user.target
to save power on the Thinkpad (this is in no way my service script, I tuned everything using powertop in the terminal after having had logged in, the script above stems from a brilliant user here on the forum). Could it therefore be autosuspend that is not working properly here?

Ubuntu Networking :: Remote Access Via Web Brower Over Standard Ports?
Mar 24, 2010connect to and be able to control a graphical ubuntu desktop from a standard web brower, over the standard port 80/443 - of course ideally 443 to have a secured connection. Does such a thing exist for this already? How would someone go about setting this up? I have a domain name and use dynDNS which works for certain tasks but I need another solution. Of course being behind a corporate firewall all the usual 'remote access' classification sites are blocked by bluecoat proxy and some cafes and wireless networks also block these sites

Nov 19, 2010I have a JavaCL program trying to open a port on 41xxx and it is getting permission denied unless I run it as root. I would like to grant a single user this permission for opening this port. This program runs fine on a vanilla ubuntu install but not on server. Where does Ubuntu handle user permissions for opening ports?I understand this is typically a no-no on a server but this is an unusual circumstance.

View 7 Replies View RelatedUbuntu Networking :: 9.10 - Too Many Open Ports For ISP
Apr 6, 2010A few months ago I installed Ubuntu 9.10 on my girlfriends laptop, on her request, as she didn't like Windows any more. Since then the internet connection periodically slows down due to too many open ports/connections. Always when this happens I call our ISP and usually there are around 80-200(!) active connections to various IP's.
She is not downloading torrents or anything.
She only uses Firefox and a few open tabs as people do.
Skype is open.
Wireless internet connection.
I am thinking either Ubuntu is updating more or less constantly or the ports/connections aren't closed "after use".
Ubuntu Security :: What Ports Are Open And Why
Jul 27, 2010I'm locking down my laptop. I know I can use a firewall to ensure nothing gets through that I didn't catch, and I certainly plan on using one, but in the meantime, I want to know what exactly is running on my system.
nmap localhost returns:
Code:
james@james-linux:~$ nmap localhost
Starting Nmap 5.00 ( http://nmap.org ) at 2010-07-26 23:33 CDT
Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1.
Interesting ports on localhost (127.0.0.1):
Not shown: 994 closed ports
PORT STATE SERVICE
25/tcp open smtp
111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
631/tcp open ipp
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 0.18 seconds
However, I know that localhost goes back to the loopback interface, 127.0.0.1. So, to see what was really open, I ran nmap 192.168.0.108, which is my laptop's IP at the moment.
Code:
james@james-linux:~$ nmap 192.168.0.108
Starting Nmap 5.00 ( http://nmap.org ) at 2010-07-26 23:33 CDT
Interesting ports on 192.168.0.108:
Not shown: 996 closed ports
PORT STATE SERVICE
111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 0.14 seconds
Now if I understand correctly, I can attribute 139 and 445 to my Samba share. That I'm okay with. What I don't know is 111 and 2049. Does anyone know what these ports are, what's running on them, and how I could turn them off, supposing that they are a security risk?
Ubuntu Security :: Ports 21 / 110 And 143 Are Open?
Mar 18, 2011I'm getting heat from the head networking office that ports 21, 110, and 143 are open. I can telnet to those ports from a remote machine (not localhost) and get a prompt. There does not seem to be anything listening on those ports according to netstat. I've tried using iptables to discard all traffic to a from those ports but I can still telnet to them. This is a lucid desktop machine.

View 1 Replies View RelatedUbuntu Networking :: Why 5 Digit Ports Open In 10.10
Jan 2, 2011I have been running Ubuntu 10.10 and have found that at any time I am connected to the Internet that I will randomly see high port numbers open when doing a port scan on my computer all are in the unknown listings with five digit numbers so I don't know what is going on or who is using them. Please check your system to see if you are having the same thing happen by using network tools and filling in your local ip address in the port scan tab. If you shut down your Ethernet interface and run port scans the high ports are no longer open. this will at least keep whoever is using your ports at bay when you are not using the net.

View 1 Replies View RelatedUbuntu Networking :: Trying To Open Two Ports - Connection Refused
Apr 12, 2010I forwarded ports 28900(TCP/UDP) and 5029(UDP) to my linux box for a game. Testing my ports with a website now shows these ports as "connection refused" rather than "timeout" which means the connections are getting to my system but the iptables are blocking them. But I added 28900 as a test and it still won't accept anything on this port. This is my output of iptables -L
root@BPC3:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:28900
Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)

What do I need to do exactly to add exceptions for 28900 TCP/UDP and 5029 UDP?

View 3 Replies View RelatedUbuntu Networking :: Checking For Open Ports Remotely
Aug 19, 2010I'm trying to set up an SSH connection from my school to my home, but not on port 22. I originally tried port 2222, but it didn't work. I called my school IT people and they said they block that port. I asked if they care if I set up an SSH and they said no, but that they wouldn't tell me which ports are blocked and which are open for "security" reasons (which I guess I can actually understand). They suggested just using port 22 or 222, but said if a ports open I can use it.
My question is, can I check ports without setting up SSH? It seems like a hassle to try a different port every day on my home SSHD file, come to school, see if it works and repeat. Is there a way I can check my computer home for connections that could connect, even if there isn't a service listening? I don't know how to do that, or even if its possible. If not, I suspect I'll just try a few until I find something that works, or just go ahead and use 22.
