Re: Color highlighting of arbitrary "tail -F'ed" text ?

Maxim -


Following on Moish's first idea you might want to take a look at 
http://brianin3d.wordpress.com/tag/bash/ (script is at 
http://brianin3d.googlepages.com/line_lite.sh) for a script that inserts 
vt100 escape codes based a pattern.

Hi,

Someone has a good recommendation for a log syntax highlighter ?

I have my application logs where I need to quickly highlight some

Could some one please suggest a suitable tool as I've tried some 
project but the hardly work.

If it's formatted ( or would be since it's your application ):

1. Add relevant syntax for vt100 terminal or the likes and display the
   output on such a terminal ( dah.. )
2. Import into a spreadsheet.
3. For large amounts of data, import into a db, postgres or whatever.

Re: connect win32 to linux with host-to-host usb cable

[Yaacov Fenster - System Engineering Troubleshooting and other stuff]

Here are a few ideas/questions:
a) Connect a USB CD and boot from it to Linux.
b) Bringup a virtual windows session under vmware and use the windows to 
windows software. (http://www.vmware.com/support/ws3/doc/ws32_devices5.html)
c) Boot the laptop from a diskette and move the files over the network.
d) If you don't have a network connection, you can use an USB NIC.
e) Does it have a parallel port? Or anything else other than USB?
f) Are you going to be synchronizing on a continuous basis, or is this a 
one time shot?

Re: connect win32 to linux with host-to-host usb cable

[Yaacov Fenster - System Engineering Troubleshooting and other stuff]

There is a significant difference, since this connects you to a 
"normal"  Ethernet cable in which you have a 1 to many relationship 
(using TCP/IP) with other computers instead of a dedicated 1 to 1 
relationship with a dedicated computer for which there doesn't seem to 
be a TCP/IP connection ("networking over USB for Linux").

Given the numbers that you mentioned, you should be all set with 1-2 USB 
NICs.

hmmm.. what's the difference between this and a host-to-host cable, 
it's actally the same only packaged differently.

How often do the clients need to connect to the server and for how long?

for downloading (and sometimes uploading) lectures mp3s to a linux box 
with special program that sort this lectures. I assume it is about 10 
minutes of use, and that it'll be used about three times a week.

How many client laptops are there ?

Not too many three or four.

Re: [OT] buying a domain name

Checking their site shows "Register your Domain Now! Only 8.95$"
If you take a look at the details 
(http://www.hostcentric.com/SharedHosting/Unix.asp), you will see that a 
year of registration is 8.95$. A year of parking your domain with e-mail 
is 5.00$ a year.

Amazon included) that may be of interest to some members of this mailing

appropriate fields


I am interested in sending the books all together. In other words - take 
one, take all. All of the books are in good (or better) state.
Any reasonable offer will be entertained including the possibility of 
donating them to a good/common cause.

Re: binary diff

Perhaps you could first convert the binary files to text representation 
(od --address-radix none) and then preform the comparison in that 
dimension?

hi

i am looking for something like 'diff' which can compare binary files

the same as what diff does for text files.

i though of using xxd with a regular diff, but that doesn't help, as 
if there is one byte missing, all lines are shifted which means they 
are different textually, when they are not really.




thanks,

This time, a similar warning dialog box popped up too, and I clicked at
it, but it was probably another dialog box, because immediately after
it, the standard dialog-box popped up. Maybe the first dialog box
warned me about a problem. Maybe the problem had anything to do with an
action that could not be done due to less enough disk space (the host
had about 3GB free space, which is OK for normal things, but may be too
little for software like VMware with its monster files).

Looking for Backup solutions for Linux

[Yaacov Fenster - System Engineering Troubleshooting and other stuff]

Folks -

We are looking for some backup solutions for a Linux based file server. 
Up until now we have been burning DVD's, but as the volume of files 
grows that is becoming a less manageable solution. In general we are 
talking about amounts of up to 20Gb per backed up volume with about half 
a dozen volumes.


Ideally we should be able to backup multiple full copies (over time) of 
a volume (Weekly backup for example), coupled with incremental backups 
of the volume (Daily backup for example).


One option that comes to mind is a dedicated file server, but that means 
that the backups are not physically removed. On the other hand using 
removable disks (USB2.0/Firewire) means that we dedicate a significant 
storage capacity (And cost) to each backup.


Ideas anyone?

   Thanks in advance

  Yaacov
