Debian Configuration :: Cannot Open Java Socket - Port (9955) Closed
Feb 26, 2010I have a java application that I wrote recently. It runs off port 9955. The application runs great on my mac server. When I installed it on my linux box i cant get to it from outside the box. A port scan shows the port as closed. I flushed my iptables, did not help. I can telnet into the app locally, from the server and it works great. I cannot telnet from outside the server. I have a reference to the application in /etc/services as a tcp port (which it is).
netstat shows it as listening
netstat --listen
tcp6 0 0 [::]: SimpleSocketTest [::]:* LISTEN
netstat -anp | grep 9955
tcp6 0 0 ::: 9955 :::* LISTEN 1484/java
Debian Configuration :: When Shutdown Screen Always Stays On And Then It Hangs
Dec 12, 2015I'm using Debian Sid xfce on my lenovo laptop. When i try to shutdown, the screen always stays on (the fans turn off). It says "reached target shutdown", then this happens: [URL] .... and then it hangs. I have to press the power button to shut it down. (I have the same problem with reboot). I had the same issues with Jessie.
Things i tried so far and didn't work:
Code: Select allshutdown -h now
shutdown -p now
halt
poweroff
systemctl poweroff
init 0
I edited /etc/default/grub and added the following options at "GRUB_CMDLINE_LINUX_DEFAULT":
acpi=force, acpi=off*, acpi=noirq
*acpi=off: shutdown (not reboot) worked a few times but i didn't have wifi and power manager didn't seem to work
none of them worked..
I have no energy or wake up options at my BIOS.
I found out that i can normally reboot with the Alt + sysrq + REISUB key combination.
Debian Configuration :: Console Dims On Booting And Stays Dark
Oct 25, 2015Since moving my debian server over to a Gigabyte H97N-WIFI motherboard the console dims on booting and generally stays dark. Strangely the screen the brightens up if I go to an emergency shell, but if the boot runs successfully I don't see the resulting login prompts. Also, during the boot process the messages to the console are too dark to see.
I've tried the i915.invert_brightness=1 fix mentioned here [URL].... but that seems to have no effect. I'm assuming that this has something to do with moving to intel graphics as my previous hardware had a radeon graphics card and didn't display this problem.
Debian Configuration :: Icon Becomes Unusable Although The Connection Stays Alive?
Feb 13, 2010I just recently updated wicd from backports on lenny to version 1.6.2.2. And with my static ip configuration in wicd, when i click on the Scripts button in the network profile properties window the gui part of wicd totally freezes. This literally means that the tray icon becomes unusable although the connection stays alive. I would like to setup some scripts to automatically activate my vpn connection through pptp, which already works manually, but i would like to do it somehow through wicd. The wicd wiki talks about it vaguely so i figured i try it. I also tried to post this question on the wicd forum but registering is disabled for the time beeing.. though luck i guess.
So anyway does anyone else has these sympthoms with the backports version of wicd ?
Debian Configuration :: ZTE MF112 Modem Setup - Light Stays Permanently Red
Oct 1, 2010I recently got an upgrade from my mobile broadband provider (3 UK) that included a ZTE MF112 modem. I found that (unlike the Hauwei modem that preceeded it) this item did not work "out of the box". After a bit of googling around I decided that a good starting place would be to upgrade the OS on my laptop. I've been meaning to do this for a while anyway so have just installed Squeeze (the i386 version, on Thinkpad x61). I think it's now pretty close to working "out of the box" but annoyingly isn't quite there. I thought of getting a ZTE modem to work say that usb-modeswitch needs to be used to make it not load as a cdrom. However, it appears to load correctly without any alteration (in fact, adding the /etc/udev/rules.d/zte_eject.rules file I have found described appear to do the reverse and make it load as a storage device - at least an icon for it appears on screen).
lsusb correctly lists it as device 19d2:0031 and identifies the device as a ZTE MF636 (though it says MF112 on the package). Looking at the Network Connections tool there is an entry for 3 mobile that is, afaik, correctly configured. If I click on the network applet on the toolbar, there is a bit of contradiction: towards the top of the drop-down list it reports mobile broadband as not enabled, but further down under the "available" list is an entry for "3 internet". I haven't paid too much attention to the not enabled entry because it also reports the wired network as not managed, so maybe this is just a quirk of network manager. - I know you have to comment out eth0 entries in /etc/network/interfaces to have network manager deal with the interface in Squeeze. There are no entries for the mobile connection in the interfaces file.
If I click on the 3 internet entry the applet goes momentarily into trying to connect mode (the circling dot) but very quickly pops up a Disconnected box, and that's all that ever happens. I note that the light on the modem stays permanently red. On the old Huwei it started green but went blue, and I think I read something about it also changing colour on the ZTE. On the other hand, the Hauwei didn't show up on the network manager list until the light had turned blue, whereas this does seem to be there. It looks as if the problem is something fairly trivial since the device appears to be both recognised and (almost!) correctly configured. How to sort this.

Server :: Open SMTP Port On Router (which Connects LAN To Internet) Also Needs To Open?
Apr 14, 2010I have sendmail running on my centOS 4.6. My lamp server also runs on it. I want to send mail through php mail function. when i execute php page, which fires the mail function, it takes so much long tim1 say even 1 minute, and at last displays that message sent successfully. Suppose, destination address is [URL].... I did not get any mail there. My server is running in LAN. I checked the status of sendmail, it shows me that it ios running. when i issue "nmap localhost" it shows me that SMTP port 25 is open, but when i issue "nmap myserver" (192.168.1.20 myserver ( written in hostfile)), it does not show that SMTP port is open.
I checked the /var/log/maillog, one person in my previous post advice me to see that. There it shows that message is accepted for delivery...but i do not get any mail in my destination, even not in spam folder. One more confusion is that, in my case my server is in LAN and if I am at all enable to open the SMTP port on it, does i need to open SMTP port on my router (which connects my LAN to internet) also needs to open? I think no, because SMTP is application layer protocol, it will wrap my mail in IP packet, which router just need to forward. am i right?

Feb 11, 2015I've bought a new notebook. The hard drive won't stop spinning down and then spinning up again during load. I don't want HD power saving, so I disabled it within
1. /etc/hdparm.conf
Code: Select all# -B apm setting
apm = 255
# -B apm setting when on battery
apm_battery = 255
It didn't work. I can still hear the HD spin up. It's annoying in a video game because things just suddenly stop for a second.
2. /etc/udev/rules.d/50-hdparm.rules

View 3 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.
