I'm looking for a tool for Debian Linux that can measure the synchronisation performance between two desktops.
I'm using RADClock instead of the NTP client to synchronise my desktops.
anybody knows any tool to measure cpu performance on opensuse box, graphically would be great.

View 2 Replies View Relatedhow do you measure performance on a computer?I know there are benchmark sites, they do give a general guidance in selection. However, I want to learn how to build a cluster from commodity parts and want to make sure it is equivalent to a specific server in performance.I know clustering is a bit abstract and it will be difficult to measure direct performance and compare it to one specific board. I am fine with that

How can I get the app to load, terminate immediately and give me the startup time?
I would like to measure the amount of traffic my webcam is sending. What is the best way to do this? I tried iostat command, but i do not see the webcam traffic back.

Ideally something like the "time" command or a profiler, but for network usage.
In bash shell, is there a simple way for me to monitor the time taken to run a script and output the time taken?

View 5 Replies View RelatedI just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

View 3 Replies View RelatedAccording to the manual of "sar" in Unix systems (computerhope.com/unix/usar.htm), it allows to determine the number of accesses to system buffers (lread and lwrite). Thus, we can easily calculate the cache hit ratio of I/Os via the system buffer.
However, "sar" in Linux only measures I/Os to physical devices (as bread and bwrite), instead of those to the system buffer (linux.die.net/man/1/sar)
I need to measure cache hit ratios for I/Os on Linux system buffer, and was wondering if there's a way to use "sar" or any other similar tools to determine such ratios.
I use Thunderbird in MS Windows and it synchronises with Hotmail.
The standard Ununtu mail programme does not appear to do so.
Have tried without success to download Linux Thunderbird.

I have two 1TB hard drives, one in my Linux server (running Debian, but I thought I'd ask here anyway) and one in my Windows desktop.
What I would like is a file synchronization program that will automatically (or scheduled via cron) synchronize my hard drive on Linux with my hard drive on Windows via Samba.
My phone is dead or dying so now is a good time to look for a FOSS replacement for Nokia PC Suite and Outlook -- the only reason I run Windows.
Is there any solution (or combination of solutions) that supports synchronising personal information manager (PIM) data -- most importantly names and phone numbers, calendar/schedule and notes -- with any model of cell phone?
EDIT:
SyncEvolution looks promising and there are reports of it working at least adequately with several phones including the interesting for Linux people Nokia N900 but OS-wise it only claims compatibility with ubuntus and debian 4.0, not beloved Slackware; maybe that's more because of what people have tried than because it doesn't work. As the name suggests it works only with Evolution, perhaps not the first choice of email client and PIM.
i had tried several restrict options and disabling the slackware "no serve to anyone" default. i want the slackware system to host the ntp server for other devices to sync with so im not so hard on the remote ntp servers.
Code:
# Sample /etc/ntp.conf: Configuration file for ntpd.

We have a Linux system serving as a storage. As it is running out of free space be bought a new server which should replace the old one. We would like the outage during the migration to be as short as possible. The plan is as follows (actually very similar to XEN live migration):
1. Copy the data to the new storage
2. Stop access to the old storage
3. Synchronization of data
4. Set the new storage as the primary one.
I was thinking of rsync, but the first phase (building file list) takes extremely long, because there are millions of files. Is there any other tool which whould be more suitable for it?
I have two processes that share a piece of memory, and i want to use the shared memory to send data from one process to the other. it's like a simple consumer-producer problem. when the producer fills the shared memory, it waits until the consumer can consume some data in the memory; the consumer needs to wait if there is no data in the memory. The thing gets complicated when both threads are allowed to sleep and wait for the other to wake it up.
i wanted to use condition variable of pthread for synchronization, but it doesn't work in multiple processes. i tried semaphore, but it's quite complicated and i still cannot make it right. I believe it's a common problem and someone should have written similar code before, or maybe the code is even wrapped in a library, but when I search for it on Internet, I only found information about how to share memory between processes. Does anyone know where I can find this kind of code or library?
I'd like to get the 13.0 "synchronized to <time server>, stratum <stratum>" messages back on 13.1.
- On 13.0, running ntpd 4.2.4p8, reassuring messages appeared in /var/log/messages like "synchronized to 211.233.84.186, stratum 2".
- On 13.1, running ntpd 4.2.6p1, there are no messages in /var/log/messages to confirm that time is being synchronised.
rc.ntpd on both starts ntpd with the same options. /etc/ntp.conf is identical on both, a "get it working and then make it secure" version:
Code:
cat /etc/ntp.conf | grep -E -v '^$|^#' cat /etc/ntp.conf | grep -E -v '^$|^#'
server in.pool.ntp.org
server asia.pool.ntp.org
server 127.127.1.0
fudge 127.127.1.0 stratum 10
driftfile /etc/ntp/drift
According to Linux Home Networking, synchronization can be checked using ntpq -p. This shows synchronization is working. I would prefer to see that confirmation in /var/log/messages without having to run a command manually to check it. How to get the old messages back?
I'm having difficulties with ntpd on my CentOS 5.6 install.
It all starts well; the server connects and synchronizes with a couple of public ntp servers:

I need a good bi-directional sync. tool like unison, that would work properly over ssh and allow manual decisions and merging if both sides (local&remote) contain changes. unison meets most of my needs, the only drawback is the compatibility - it needs to be installed on both sides, and with the same version. Nowadays it's a bit of a problem, if you have say OS11.3 on one node, SL3 on the other and a MacOS on the third. In my view one only needs the ssh connection, all the rest of the file analysis should be done by the local software. Anyone knows such a tool?
View 3 Replies View RelatedI would like a seamless way of having personal files encrypted (at this point I am only worried about the home directory) and synchronize these files between different computers and with an external hd.
So far my partial solution is:
1) Default Ubuntu eCryptfs solution;
2) Unison to synchronize between the upper layers of both computers via ssh (operating on the /home/$USER mounted by ecryptfs) and also between one computer and the external HD;
3) Don't know about the external hd.
Reasons:
- I don't want any pain about data loss or data leak if my hardware gets stolen;
- Data in /tmp, /var and swap are not that important for me right now;
- It is very important to synchronize fast, incrementally and properly: propagating deletions rather than reverting and detecting change-change/change-delete conflicts before miss-propagating changes, which as far as I know only Unison is good at;
- Even if I could set the same passphrase on both computers (I guess I can, but Ubuntu does not offer me to choose the ecryptfs passphrase) I want to see the true filenames that are being synchronized;
- If possible I would like to simplify the whole scheme so that each computer is doing its own job seamlessly, and operating on the upper decrypted layer looks simple and robust;
- I would like a more general and easy-to-use scheme for the external device, so other folks use it too;
- If possible I would like ext4 backups, so it remembers file permissions etc... however it would be nice to be able to open it from Windows.
Are (1) and (2) above really good solutions or am I missing something? What are the best solutions for (3)? So far I have seen cryptsetup/palimpset and truecrypt. The more native and floss the better, but being crossplatform is nice. What are the pros and cons, and what's their relation to FreeOTFE and other Windows tools?
I work on Linux Regression testing and I am writing a script to automate(shell scripting) the netperf tool when I need to determine the performance(throughput) of agent and client(individually) and I shall be running a shell script on (lets say) client first. But how to obtain the synchronization between them both as I need to execute a command even in board(agent) side to get the script going.
