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?

Feb 7, 2010I'm trying to setup oracle10g but, whenever I try to go to my database homepage http://127.0.0.1:8080/apex I get an "unable to connect to" error. Only reason I can think of as to why I can't connect to it is because my ports aren't open. I also recall SELinux complaining about something awhile ago, I can't seem to bring that up any more for some reason.

Mar 28, 2010I've been struggling for days trying to open port 53 and 25 but can't get it to work. My iptables at /etc/sysconfig contains the following:

But when I try to do telnet from an external machine, e.g:

Fedora :: Close Minecraft - Freezes And Stays Open For A Long Time
Aug 10, 2011I installed Fedora 15 last week, on my main PC, and I absolutely love it. Defintely my favourite operating system. Now I have a few questions. I thought I would put them all in one thread, instead of making seperate ones. I did search before I posted, and I cant seem to find any solution to my problems. So here it goes.
First question, I am using evolution for my e-mail program/client. My email addresses are all hosted by hotmail. Now I have set them all up correctly, but cant seem to send e-mails(I recieve them perfectly fine). I am using the "smtp.live.com" server, and using SSL encryption. I have tried messing with the settings but have had no luck. Has anyone figured out how to fix this?
Second question, I play minecraft frequently, and I am currently starting the program via terminal [java -jar /home/username/minecraft.jar], which works flawlessly. However it is too slow(open terminal, type it in. I need a simple click), is there any other way to start minecraft?
Third and last question, What is the best way to close minecraft? I notice if I just close it(via right click, and close, or clicking the X) it freezes and stays open for a long time. Is there any better way to close it?
Fedora :: Cleaning Up - Make Epiphany Remeber Tabs After Close Browser And Open It Again?
Nov 13, 2009I just moved to Fedora 11 from Ubuntu and I am very happy, not even thinking to go back to Ubuntu (because of gma500 driver support). How can I clean up Fedora? On Ubuntu I could go to Synaptics, remove Installed (not residetial) packages, I coud use terminal sudo autoremove, autoclean, clean. On Fedora I found out only one so far: yum clean all. Is there anything else I should now, can you share with me how you are cleaning up your Fedora? Second thing, which is not only related to Fedora, is there any chance to make Epiphany remeber tabs after I close the browser and open it again? Don't really want to use any other browser.

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 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 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?
OpenSUSE :: Open Firewall Ports Without Yast?
Jan 23, 2011how to open firewall ports without using yast. The reason I'm asking is because I'm working on a .sh script for the installation of a couple of programs. Some ports need to be open for the programs to work, I find it really annoying to go to yast and type the ports manually every time. I've looked at /etc/sysconfig/SuSEfirewall2 but can't seem to find anything, I also know that after the changes I will have to stop start the firewall by running:
SuSEfirewall2 stop
