At work, I'm in a Solaris environment working with csh, and $PATH is populated with anywhere between 10 and 20 entries.
Last week, every command I issued (even "ls") took several seconds, if not an entire minute, to run. Once I moved "/home/sybase/bin" to the end of $PATH, certain commands... (2 Replies)
hey guys,
We have two Sun x2100 servers running RHEL5 in a test environment. Both servers are fresh OS installs and hooked up to the same network switch.
When ssh'ing to one server, there is a significant delay, while ssh'ing to the other server, the connection is almost instant. We are... (2 Replies)
Hi All,
Please let me know the command to restart the network interface and enable it on boot in AIX, similar to /etc/init.d/network restart in Redhat.
Thanks,

Hi Guys,
I've inherited a mess of an infrastructure in my new job, there hasn't been a sys admin in post for about a year, so things are falling apart. The first thing to break after I started was the printer server. I have it working again, and people can print, however it's very slow, slower... (0 Replies)
I have identical M5000 machines that are needing to transfer very large amounts of data between them. These are fully loaded machines, and I've already checked IO, memory usage, etc... I get poor network performance even when the machines are idle or copying via loopback. The 10 GB NICs are... (7 Replies)
Hello everyone,
I've been a life long Unix/Linux user but I'll be the first to admit I have little specific AIX knowledge at this point and I've inherited these systems for better or worse so please forgive if I ask something in the wrong context. And yes, I've searched google for 3 days now :)... (3 Replies)

rwho
rwho(1) User Commands rwho(1)NAME
rwho - who is logged in on local machines
SYNOPSIS
rwho [-a]
DESCRIPTION
The rwho command produces output similar to who(1), but for all machines on your network. If no report has been received from a machine
for 5 minutes, rwho assumes the machine is down, and does not report users last known to be logged into that machine.
If a user has not typed to the system for a minute or more, rwho reports this idle time. If a user has not typed to the system for an hour
or more, the user is omitted from the output of rwho unless the -a flag is given.
OPTIONS -a Report all users whether or not they have typed to the system in the past hour.
FILES
/var/spool/rwho/whod.* information about other machines

rwho does not work through gateways.
The directory /var/spool/rwho must exist on the host from which rwho is run.
This service takes up progressively more network bandwith as the number of hosts on the local net increases. For large networks, the cost
becomes prohibitive.
The rwho service daemon, in.rwhod(1M), must be enabled for this command to return useful results.
