Ubuntu Networking :: Possible To Ssh Or Remote Desktop Computer With Such High Ping Rate?
Mar 1, 2010I have been trying (unsuccessfully) to remote access my girlfriend's Ubuntu machine to fix a few things. The problem is that she lives in Japan and I live in RI, USA! Is it even possible to ssh or Remote Desktop her computer with such a high ping rate? (average ping time is 300ms) If so why can I not connect?

Networking :: Print AND Real-time Output Of PING Command ?
May 3, 2011Let's say I am pinging a host, and want to output to a file each reply and its timestamp of when this started.
I know that it can be done with a loop and a shell script. Something like this
DO
echo "$(date)" >> results.txt ###includes the time and outputs results to txt###
ping -c 4 HOST >> results.txt ###a total of 4 pings at a rate of 1 per second###
REPEAT UNTIL USER PRESSES CTRL-C
Now, my first issue is that I need to be able to see results real-time as well.
Is there a way one can print to BOTH a screen and output? If one uses the ">>" command, it is essentially sending everything to the file. Running another ping command in parallel is not an option.
CentOS 5 Networking :: ICMP Ping Latency Grows Over Time
Apr 20, 2011I have a dedicated host on my lan to monitor other hosts/services using Nagios. I'm in the process of migrating to Zabbix on that host to perform the same purpose. Both Nagios and Zabbix monitor icmp ping latency (Nagios uses ping, Zabbix uses fping) and over time the latency to other hosts grows until threshold alarms are triggered. In one week, the average latency grows from sub-millisecond to over 100 milliseconds, and continues to grow until the Nagios host is rebooted. I have verified the latency numbers using ping/fping from the command line on the Nagios host.
The problem is that pings from the monitored hosts to the Nagios host show normal latency at the time the Nagios host is showing high latency from itself to the monitored hosts. The Nagios host and monitored hosts are all connected to the same Dell 24 port gigabit switch. I already posted this question on the Zabbix forums with a graph of the latency but there were no answers. [URL] why the icmp ping latency is growing over time and how I can fix it short of rebooting the host on a schedule.

Ubuntu Networking :: Unable To Ping Over Wireless But Can Ping Over Wired?
Jul 24, 2010I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.

OpenSUSE Network :: Nmblookup Resolves But Cannot Ping Netbios Names Or Ping FQDN
Feb 23, 2011This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

Networking :: BIND9 SLOW Ping When Ping By Hostname
Feb 1, 2011I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:

Ping by IP - the responses come VERY quickly one after the other:

Networking :: Can't Ping Past Gateway / Can Ping Server From Outside
Apr 29, 2010So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

View 3 Replies View RelatedGeneral :: Proportion Of Down-time Versus Profitable Time
Oct 15, 2010I admit this has been a particularly bad year for me, but it isn't THAT unusual by my standards. I typically spend I would reckon quite honestly about 70-80% of my time with computers just fixing stuff up that either I broke or was broke in the first place. Usually it's the latter by some considerable margin. That's really inefficient, isn't it? I just wondered what others' experiences are of this phenomenon. Obviously I don't do computers for a living or I would have starved years ago. So what is the Panel's consensus view on the percentage of wasted time we should expect to spend, on average, "running just to stand still" on maintenance tasks?

View 2 Replies View RelatedGeneral :: Sound Lacking High And Low End
Jul 1, 2010Is this just a standard characteristic of Linux or is there some way I can EQ all the audio? I've had nothing but problems with audio sounding like a scratched record in Linux. It would skip, crackle and break up no matter the source or volume. Found a solution that one to simply remove PulseAudio.
I'm using Altec Lansing ADA885 speakers with 8" DVC subwoofer. System response is good down to ~28Hz but it sounds like a cheap boombox. Last time I had these hooked up to a Windows (XP Pro) system, the bass was deep and full. Very audible all the way down. Now it sounds like the audio is boosted at center frequencies and overly cut on high and low end.I even tried putting in a PCI Turtle Beach Santa Cruz 5.1 card and the sound did NOT improve.

General :: High Memory Utilization By System?
Nov 11, 2009I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]

mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si

Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
