Debian Configuration :: Ping Fail As User Works With Root?

Oct 13, 2010

I have a very strange problem.ometimes, yes sometimes not all the time, I get a Destination Host Unreachable when I ping a computer on my network. If I switch to root using su I can ping that same computer. Here is a screen shot:

joseph@laptop:~$ ping 192.168.1.14
PING 192.168.1.14 (192.168.1.14) 56(84) bytes of data.

Debian :: Why $http_proxy Only Works For Root User In Apt-get

Feb 24, 2010

I just setup a debian OS(in emulator) and trying to use apt-get update. When I log in as root and do:

export http_proxy=http://proxy.com:9090
apt-get update works

If I use another user and ssh to this debian, sudo apt-get update will fail to work because it don't use the proxy. I try to do the export http_proxy stuff again but still not working. echo $http_proxy showing it already set correctly...

p/s:
I have a workaround by adding this lines in the apt.conf
ACQUIRE {
http::proxy "http://proxy.com:9090"
}

but I really don't want this solutions because I want to easily disable the http_proxy in command prompt (by unset it).

Debian Configuration :: User Cannot Shutdown While Root Is Logged In

Jun 29, 2011

on my netbook I've tried to make possible for my user to shutdown without needing a password. battery could run low when I'm not in front of it. Editing sudoers has allowed my user to shutdown the system, but Gnome still prompts me for the root password whenever root is logged in too. That's usually the case, because to avoid entering the root password multiple times whenever I need elevated privileges and not wanting to cache the root password, I keep a Root Terminal always open.

Debian Configuration :: When User Is Admin Root Password Is Still Needed

May 7, 2015

I'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.

I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.

Code: Select allgroups fred
fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth

I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.

Applications :: Program Works As Root But Fails As User

Jan 21, 2010

I can't get a program (wbar) to run directly from my user account, it fails saying "Image not found -> maybe using a relative path?". But if I run su -c "wbar", it shows up and manages to load the image. I think it has something to do with ImLib2 or whatever loads the image. I checked permissions on libImlib2.so.1 and it's world-readable and executable. Can libImlib2.a be causing this problem, set to 644? What else should I be checking?

Ubuntu Multimedia :: Karmic: Sound Works For Root But Not For User

Feb 7, 2010

I cannot find a post that matches this scenario...the id created during the install (from CD) of Karmic has fully usable sound. However, users created from the Users and Groups app do not.

I have made sure that all users are defined to the audio, pulse, pulse-audio, and pulse-rt groups. No luck.

I have followed every step I have read having to do with the alsamixer. No luck.

I have verified that alsa and linux itself are at the latest versions.

Debian Configuration :: SSH, Ping And ARP Not Working As They Should

Mar 13, 2010

i am running debian testing and the last few days i was trying to ssh to another pc on my network and i was getting an error like there was no machine with that ip! then i tried pinging to it with no luck! ARP was the only tool that returned the MAC address of the machine and that is strange i think. i realised then that i could only ping the gateway and localhost (127.0.0.1 not my ip). after editing my /etc/hosts, i could ping my ip as well. what is so wrong? here are some useful things:

my new /etc/hosts:
jack@debian:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 debian.local debian

Debian Configuration :: Can't Ping Windows Xp Machine

Jan 23, 2010

I recently did a clean install of Debian 5, and a backup program called BackupPC. Both machines are on a small local network served by a router. Both machines have statically mapped IP addresses, done by the router via matching MAC addresses in a table of corresponding IP addresses (192.168.0.2 (HP-PC-XP), 192.168.0.3 (Debian). I configured Backup PC correctly (I think)...Upon running Backuppc, the first thing it tries to do when its time to run a backup is to ping the machine to be backed up. The name of the PC is stored in a backup pc config file. (I believe BackupPC does a DHCP request with the machine name to get the ip address, but not sure). Running the backup results in BackupPC tells me that it can't ping my xp machine. If I open up a terminal window in debian, i can successfully ping my xp machine when i use the ip address. 92.160.0.2 If I ping using the host name of the xp machine (e.g. HP-PC_XP), the ping command displays some ip address i've never seen...something like 63.123.155.104....how is it getting that and how can it be corrected?

I recall that nslookup looks at the local hosts file first to resolve the name....i look in my hosts file and found no such address (only contained localhost)....now what?

Debian Configuration :: Block/as-iosched.o Causes Kernel Build To Fail

Jan 15, 2010

I am working with linux-source-2.6.30 from squeeze.

The only changes I made in the config file were the processor type, and I disabled CONFIG_SYSFS_DEPRECATED_V2 to avoid some warnings from udev.

When I tried to build the kernel package, this is what I get:

(The bottom bit is from 'time').

Searching for this error turned up a plethora of results, none of which seemed relevant.

I see that it tells me to file a bug report, but I'm not sure if that is meant for the Debian kernel team or upstream.

Debian Configuration :: WiFi Connects But Can't Ping - No Internet

Aug 27, 2015

I've been using Debian for about 6-7 months now. I've had a bit of a major networking problem for the past 4 months or so that I've been trying to fix - specifically, it started when I upgraded to Jessie. I can connect to wifi just fine, and sometimes I can even use the internet for brief periods of time (exceedingly rarely). Then... nothing. No network access, period. I can't ping any outside servers, I can't ping other computers on my network, and I can't even ping my router. Pages I try to load just stay "connecting" for all eternity, network printing fails, and so on.

So after four months of searching online (I've read through way more wireless documentation than I care to say), I finally gave up and admitted that maybe I screwed something up during upgrade to Jessie (as a matter of fact, I did, I had to do the upgrade in two increments [somehow] because my root partition was too tiny by mistake) and I did a clean install. Since I had /home on a separate partition, I was able to keep all my user files, but all settings regarding networking were wiped. So after installing firmware-iwlwifi so I can use my wireless card, I tried connecting to wireless! Success! Then I tried connecting to the internet... success! Briefly. The next morning I tried using the internet again, and it failed in exactly the same pattern as before.

I don't know much about what's going on here, but here's what I do have available:

I do have to use firmware-iwlwifi, which I installed by doing apt-get install firmware-iwlwifi. I don't think it's an issue with the wireless card itself (hardware-wise), the laptop dual-boots Windows 7 (that I never use anymore), and Windows 7 is able to connect to the internet just fine. Connecting directly to my router by ethernet cable works fine, I have perfect internet/network access then.

I can confirm that my laptop is receiving an IP address and that it is using ARP correctly to get the MAC address of my router (I confirmed this by doing the arp command, it has the MAC address correct, I checked from another computer with my router's config page) All other computers on my network work perfectly with my router. To confirm the router/its configuration isn't at fault, I did a full factory reset of the router, but to no avail.

Out of curiosity I tried installing Wireshark (using an ethernet cable to download it) to monitor what happens when I try to access a webpage. I'm no expert on networking, but I noticed something out place when I compare a capture from the affected computer to a capture from one operating normally - there are a lot of STP packets showing up. I did some checking around, it looks like STP is involved in bridging and more complex networking setups (involving switches, for example)... but it shouldn't be found on a home network, especially where there's no bridging whatsoever. These STP packets don't show up on packet captures done from any other computer. I've attached a packet capture from the affected computer here, since the forums won't let me attach a .pcapng file.

Here's the output from a few commands I ran during past troubleshooting sessions:

Code: Select allsudo ifconfig
eth0      Link encap:Ethernet  HWaddr e0:db:55:b5:fe:06 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

Debian Configuration :: Network Malfunction After Possible Ping Attack

Apr 8, 2010

I would like to ask something. Today my network Internet access suddenly slowed down, after inspecting the problem the hard way we disconnected one of our servers(ip=190, debian squeeze) from network and the network was alright again. When we plugged it back in, following symptoms were observed: computer 190 pinged gateway app. each 6th time. gateway(debian lenny) pinged computer 190 app each 6th time whole network Internet access was slowed down, local network functioned just fine

While pinging themselves, i ran iptraf on icmp packets on gateway and I saw what i thought was ping attack, lots of echo request coming from external address to computer 190. Blocking that address in iptables didn't help but restarting the gateway did, network Internet conenction is at full speed and gateway and computer 190 ping just fine.

My question is, what steps should I undertake in similar case (it's second time in 2 months) - to debug similar problems. Is it even possible for ping DOS to this kind of damage?

General :: Sharing Configuration (.*rc Files) Between Normal User Account And Root

Oct 2, 2010

On a Fedora Core box, I have a normal non-privileged user and I also have sole access to the root account. Because I am the only administrator of this box, I frequently su over to root for administrative tasks. The problem is that many of the user configuration I've become accustomed to are only configured on my day-to-day account (.vimrc, .bashrc, .screenrc, etc). Other than giving my day-to-day user account privileges to perform administration tasks, how would I go about sharing configuration between these two accounts?

Debian Multimedia :: Gpsbabel Now Only Works As Root On Squeeze

Feb 7, 2011

gpsbabel has always been a little awkward to get going, but it works well once it does. Out of the box on Lenny, gpsbabel just gave errors for me reading from a garmin unit, and the required solution was two steps: firstly, remove (and blacklist) the kernel module "garmin_gps". Secondly, add a udev rule like this:SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="0660", group="plugdev" and save this as /etc/udev/rules.d/51-garmin.rules.

Now, I never understood why or how that worked, but it did (on Lenny), straight away, and was listed as gpsbabel's solution here (I notice it now says MODE="666").

Anyway, now I'm on Squeeze and have the same problems again. I've blacklisted garmin_gps again, and it doesn't appear in lsmod.

I've still got my udev rule, but now gpsbabel fails as a normal user with the error:
