Performance issue

Hello all,

I just stuck up in an uncertain situation related to network performance...

I am trying to access one of my remote client unix machine from a distant location..

The client machine is Ultra-5_10 , with SunOS 5.5.1

The ndd result ( hme1 )shows that the machine is hooked to a 100Mbps network connection.. but the response is very poor. I mean, when I start working with a rlogin/rsh connection, the feedback is really slow.. it just hangs sometime and comes alive again...

Is there any way to measure/identify the connection in terms of bandwidth.. ?

Or anyother points to check out for a better performance...

I had glance on some of the tcp/ip stack tuning stuff.. but this machine dont have many remote connections, which force me to believe something else is wrong...

And big question is ..Am I going in the right direction ??

Here is the output of ndd check...

transceiver_inuse -- 0

pam_issue - PAM module to add issue file to user prompt SYNOPSIS
pam_issue.so [noesc] [issue=issue-file-name] DESCRIPTION
pam_issue is a PAM module to prepend an issue file to the username prompt. It also by default parses escape codes in the issue file similar to some common getty's (using x format). Recognized escapes: d current day l name of this tty m machine architecture (uname -m) machine's network node hostname (uname -n) o domain name of this system release number of operating system (uname -r) current time s operating system name (uname -s) u number of users currently logged in U same as u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users") v operating system version and build date (uname -v) OPTIONS
noesc Turns off escape code parsing. issue=issue-file-name The file to output if not using the default. MODULE TYPES PROVIDED
Only the auth module type is provided. RETURN VALUES
PAM_BUF_ERR Memory buffer error. PAM_IGNORE The prompt was already changed. PAM_SERVICE_ERR A service module error occurred. PAM_SUCCESS The new prompt was set successfully. EXAMPLES
Add the following line to /etc/pam.d/login to set the user specific issue at login: auth optional pam_issue.so issue=/etc/issue SEE ALSO
