I have upgraded to 10.04 from 9.10 after that, i get this strange issue.I have acutally asingned static address in the network manager applet.
Code:
mahiti@mahiti-admin:~$ sudo mii-tool -vv eth4

The system of my VPS is centos 5. I want to know if it is 32bit or 64bit. > uname -a Thu May 13 13:49:53 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
looks like 64 bit.
But
> getconf WORD_BIT
32
Looks like 32 bit.
Which is correct?
I believe the linux of my VPS is 32 bit. Because I downloaded a 64bit mongodb, found it can't start. And when I downloaded a 32bit instead, it works well.
I'm only partially new to Linux. I'm running Fedora 11. I've just set up two machines, I thought to be identical. Evidently I missed something. I had some problems getting the network started on the second machine, and I must have forgotten a name change somewhere. Anyway, after doing lot's of comparisons between the boxes, editing and renaming and re-linking the ifcfg-GigaStorey file, they are both functioning. The problem is that whenever I start or restart the network on box 2, it reports the following error:
Bringing up interface GigaStorey: RTNETLINK answers: File exists
Error adding address 192.168.1.6 for eth0.
[ OK ]
The file ifcfg-GigaStorey is linked in the following directories
/etc/sysconfig/network-scripts
/etc/sysconfig/networking/devices
code....
Like I said, it's not super critical, just annoying. The networking comes up ok, but the error is puzzling. I figure if I learn what this problem is I'll be one step closer to my Linux beanee.
I'm having problems enabling Wake-on-LAN using ethtool.I'm using ethtool 5.1 on Fedora 8. Ethtool reports that the card supports u,m,b,g for WOL modes. I can run "ethtool -s eth0 wol g", which completes without errors.If I run ethtool again, the Wake-on setting is changed to whatever I just set it to. However, when I actually shutdown the machine, the lights on the NIC don't stay on as they normally should, and any attempts to wake the machine have no effect. The machine dual-boot Windows XP, and I have enabled WOL in the driver there. When I shutdown the machine from XP, everything works just fine. The NIC lights remain on and the machine wakes up properly. So...I think I have my BIOS configured properly, and my WOL utility is working properly.

Im trying to remote power on my debian machine with gnome with the wake on lan function. I enabled it on my mainboard and was configuring my ethtool. There i see:
root@lappy:~# ethtool eth0
Settings for eth0:
Supports Wake-on: g
Wake-on: d
Link detected: yes
and after this command ethtool -s eth0 wol g i get this:
root@lappy:~# ethtool eth0
Settings for eth0:
Supports Wake-on: g
Wake-on: g
Link detected: yes
So i enabled it on software and hardware. Now im trying to sent the magic packets with a windows tool "wake on lan" I see that the package has been sent but the pc wont turn on. So when i check the ethtool settings again i see that it turned to:
Wake-on: d
So I have tried looking on the web for a solution to this, but I can't find anything. I have only found 2 posts with the same problem and both went unanswered. So I want to set my ubuntu machine to WOL with both Magic Packet and Unicast (the g and u functions in ethtool wol) wol supported: pumbg (thus g and u are both supported) I use "sudo ethtool -s eth0 wol ug" and check to see if it changed, and it does
sudo ethtool eth0
"wol: ug"
After I suspend though, only magic packet will wake it up! I go back in and check with "sudo ethtool eth0" and low and behold, it is back to only being "wol g", which is the default. For some reason it must bump back to default before going into suspend. NOTE, this is with suspend, not even a reboot or a shutdown! Even suspend will reset it to default. I have worked on adding a script to /etc/init.d, adding lines to /etc/rc.local, and adding lines to /etc/networking/interfaces, all with no change.
Any idea what is going on and why it is resetting wol back to default?? I know I should be happy at LEAST it does magic packet, but I want to know why it wont change.
I have two onboard gigabit connections and a PCI-E gigabit card, none of which seem to want to run beyond 100M. Everytime I issue the command to change speed to 1000M, it does nothing. I have tried modifying the interfaces file to make sure the command line for ethtool gets done automatically, but still no luck.
Below is the output from the use of ethtool to change speed. Since I am having performance issues with my local area networking (e.g. Samba transferring slower than the internet), I have been trying to figure out how to debug my network performance, and this was an obvious thing that stood out. The router and card are gigabit, yet don't use their full transfer rates.

Is there some traceroute-like tool that shows ports as well as IP addresses? This is more for seeing how NAT works (on my home network) than for a practical need.

View 2 Replies View RelatedI am running a test to determine when packet drops occur. I'm using a Spirent TestCenter through a switch (necessary to aggregate Ethernet traffic from 5 ports to one optical link) to a server using a Myricom card.While running my test, if the input rate is below a certain value, ethtool does not report any drop (except dropped_multicast_filtered which is incrementing at a very slow rate). However, tcpdump reports X number of packets "dropped by kernel". Then if I increase the input rate, ethtool reports drops but "ifconfig eth2" does not. In fact, ifconfig doesn't seem to report any packet drops at all. Do they all measure packet drops at different "levels", i.e. ethtool at the NIC level, tcpdump at the kernel level etc?nd am I right to say that in the journey of an incoming packet, the NIC level is the "so-called" first level, then the kernel, then the user application? So any packet drop is likely to happen first at the NIC, then the kernel, then the user application? So if there is no packet drop at the NIC, but packet drop at the kernel, then the bottleneck is not at the NIC?
View 1 Replies View RelatedI have a CentOS 5.5 machine (hosted at a remote hosting company) where "ethtool" reports that the eth0 device is currently in 10 Mbps mode, but the output indicates that it supports 100 Mbps. But if I try using ethtool to switch the device into 100 Mbps mode, it doesn't work; after running the command to switch it to 100 Mbps, ethtool reports the speed is still 10 Mbps:
[root@sls-eb5p17 network-scripts]# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full

The man page at [URL]..ethtool seems to suggest that this should have worked. Any reason why the reported speed of the device didn't change? Changing other settings doesn't appear to work either, e.g. if I specify "duplex half" instead of "speed 100", eth0 still reports "Duplex: Full".

I am looking for such a tool, very much like the one that is on Windows 7, where you can basically with one glance see how much of a volume is occupied (graphical bar) and that for all mounted volumes. I have been looking for this, but so far I have not found it.Also, important: that it is auto updated. So that it is not like a report that was generated and then does not change anymore, but a live thing

Upon starting it from prompt I noticed the following error : libv4lconvert: Error decompressing JPEG: fill_nbits error: need 2 more bits The program 'cheese' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'.

PEGASUS 192.168.0.101
When being pinged from another PC aok, but also pings back on 192.168.0.100? When being pinged from itself using ping 192.168.0.101 (or 100) all is well - when pinged as ping PEGASUS is says following:

I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work.
