Debian :: USB Ports Don't Wake Up - Have To Close And Open Lid Of LT
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 Security :: Router Has Open 5900 Port And Can't Close It?
Dec 19, 2010I've recently been taking a look at my router settings and I've realized i have my vnc port open for some reason. I don't know how or why it got opened because I've only used vnc within my private lan. Anyway, the problem is I couldn't figure out how to close that port on my router, so I just uninstalled all the vnc software from my computer so it wouldn't act like a vnc server for anybody trying to access it from the outside. So, effectively, I cannot vnc into my computer from outside my private lan, but when i port scan my public ip, the vnc port still appears open.
I'm wondering if there's something i'm missing. I'm sure it must be something in the router that I haven't figured out... something that's keeping port 5900 open.

Feb 2, 2010Just did a check on "shields up" and it says that ten of my ports are open. I get the same result with or without both shorewall and firestarter. I suspect it may have something to do with the mysql server packages added automatically during installation. Am I right. If so, what can be done about it? If not, has anyone any idea how to keep my ports closed?

View 6 Replies View RelatedDebian Configuration :: Firewall Up But Ports Still Open
Sep 9, 2011I have just switched over from firestart to gufw.I have set all incoming traffic to deny and all outgoing traffic to allow.I have rules set for incoming traffic, and have only opened 1 port on my system for torrents. My router also only has the same port opened which again is for torrents.I use "Network Tools" which is included on squeeze and do a portscan of 192.168.1.100 and 127.0.0.1 I get all kinds of crazy ports coming back as opened. What is even stranger is if I do a few scans, these ports change, so one port on one scan may come up as open, then it will disappear and a different port may show as open.
Mind you none but the torrent port is forwarded in my router, I have no idea what any of these other ports are, or why they are even showing up.What the heck is going on? I dont think this is normal? Am I at any higher risk for attack?

Debian Configuration :: How To Open Ports On Debian?
Jul 19, 2010I am trying to use thunderbird to connect to gmail. followed the instructions on the gmail help section to set up thunderbird and opened ports 995 for pop and 465 smtp on my router. When that did not work I posted on the thunderbird forum. It was decided there I had a problem with debian since both the thunderbird and router settings were right. doing more research I used nmap and netstat to check for open ports and it seems to me I only have tcp 80 and udp 138 open. downloaded firestarter hoping to solve the problem but in the events section it does not show thunderbird trying to connect to any port. Is this a case of not understanding what I am looking for here. Is there some way to open all ports on debian and then using firestarter to block the traffic I do not want.

Jun 28, 2011Yesterday I switched from CentOS to Ubuntu, and wanted to install TeamSpeak3 which runs on ports 9987 UDP and 10011 TCP. The TeamSpeak3 worked fine on CentOS before this.
It appears to be running and netstat -an reports:
Code:
udp 0 0 0.0.0.0:9987 0.0.0.0:*
tcp 0 0 0.0.0.0:10011 0.0.0.0:* LISTEN
I believe the only firewall for Ubuntu is "UFW", am I correct? If so, "ufw status" reports:
Code:
Status: inactive
I do have other things running on UDP (Counter Strike Source servers) and people can connect just fine.
When I telnet localhost 10011 I get a response from the TeamSpeak3 server:
Code:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
TS3
Welcome to the TeamSpeak 3 ServerQuery interface, type "help" for a list of commands and "help <command>" for information on a specific command. However, telnetting from outside just gets no answer, this is what leads me to believe it is a firewall in the way.

View 4 Replies View RelatedDebian :: How To Use Firestarter To Open Port To One Site Only?
Dec 6, 2010I have a question about anybody who knows how to use firestarter firewall. I'm trying to get access to a Macromedia flash site that needs port 1935 open. While it is not a big issue to open the port, I want to do it just for the server that needs it. I do not want to open it to everybody else. I wonder if anybody has any idea of how to do this. Normally I just go to www.redhotpawn.com which is a chess playing site. I then pressed on the blitz button to go into a game. But it tells me access denied, and then the site has a warning about what it means. The site that mentions that if this is the case then this port has to be open. I don't have a problem of opening the port for the one site as I trust it. But I don't want the port open for every site. I know I can go into the firewall settings and under policy I click on the allow service port for. I put in the port number, but then I don't want to select all. I want to find out what the IP, host or network that I need to allow. Basically I only want to open the port to the one site.

Jun 25, 2010I have a Suse 10.3 router with 4 network cards. 1 is to connect to the big network and thereby also the internet, 2 are for 'client' subnets and I want to use the last one as a DMZ. In this DMZ will be a web server which has to be accessible from the other 2 subnets and from the big network. I could do it with a few simple clicks in Yast firewall, but I have some issues with this firewall and there for I want to use it as minimal as possible, using Iptables.
So now I'm struggling a bit with Iptables. Basicly what I'm looking for is how to block all ports but 80 in this last subnet with iptables.
