RE: Reg : RHEL 5.0 Installatio

Hi Ram
 
Try the Fault Tolerant mode in bonding and check if u have any issues.
 
edit the modprobe.conf and change the mode to mode 1
 
alias bond0 bonding
options bond0 mode=1 miimon=100
 
and try restarting the machine check the machine .
 
I had faced a similar issue where the applications will be extremely slow when we have mode 0 in bonding. this happens bcos some switches doesnt work properly with load balancing mode 0 .
 
Regards
karthik

Yes,

I am aware of that. I believe so far I haven't posted any sensitive
data.
(Ip address is anyway should be given)
I will try the test. Actually last time I was not able to connect at
all.
After a reboot I was able to connect. But still load is 2.8+.

Weird, you shouldn't be getting any packet loss at all. I wonder if
there's
Some faulty network device? Try these tests:

1. Ping from yourself to yourself; ping localhost, and ping the proper
qualified domain name - do you get any drops then?

2. Ping from another host on the same subnet, do you get any drops
then?

3. ping from a host on a different subnet.

(also, in future be weary of transmitting lots of information about
your
servers to a mailing list, your info might be posted on the internet -
just be mindful of that).

Also, if you ping the server any other time does it always drop

1. look in the output of ifconfig and you'll see a "collisions"
field
which should have a value of 0.

2. look at the output of either "ethtool <interface>", or
mii-tool
<interface>, and you will see what the port speed is. This must
match
the port speed of your switch (your network guys will tell you
if
the
switch is
100Mb or 1000Mb etc).

Look for output like this which says the interface is running
at
100Mb/s. This is bad if you're connected to a 1000Mb switch.

Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full

Actually the problem is here. Once I reboot the server the

is
around
2.8 and I am not able to ping the server (All firewalls are
turned
off).
After sometime I am able to telnet or ping the server. While
pinging
it
drops 50% of packets.
both telnet and ssh services are enabled.

does anyone knows/have that comic picture of "tux" the Linux penguin that:

- has four pictures in it
- it defines 4 "levels" of the knowledge of tux, who is "symbolizing a
learning person"
- the first one: tux is just a Linux "fanboy"; second: tux is working, and
say's: "...stupid rpm"; three: I can't remember that:D sorry; four: tux has
a beard, and the picture says don't mess with it.

thank you, and sorry for the question, but I just can't find it on google :D
:S
