Network becomes slow and return fast only after restart network
Hi,
I have 2 machines in production environment:
1. redhat machine for application
2. DB machine (oracle)
The application doing a lot of small read&writes from and to the DB machine.
The problem is that after some few hours the network from the application to the DB becomes very slow and it returns to the normal only after: Before: After restart network:
What can it be?
How can i solve this strange behavior?

Hi,
I am trying to send oracle archives over WAN and it is taking hell a lot of time. To reduce the time, I tried to gzip the files and send over to the other side. That seems to reduce the time. Does anybody have experienced this kind of problem and any possible ways to reduce the time.

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 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)

pure-authd
pure-authd(8) Pure-FTPd pure-authd(8)NAME
pure-authd - External authentication agent for Pure-FTPd.
SYNTAX
pure-authd [-p </path/to/pidfile>] [-u uid] [-g gid] [-B] <-s /path/to/socket> -r /program/to/run
DESCRIPTION
pure-authd is a daemon that forks an authentication program, waits for an authentication reply, and feed them to an application server.
pure-authd listens to a local Unix socket. A new connection to that socket should feed pure-authd the following structure :
account:xxx
password:xxx
localhost:xxx
localport:xxx
peer:xxx
end
(replace xxx with appropriate values) . localhost, localport and peer are numeric IP addresses and ports. peer is the IP address of the
remote client.
These arguments are passed to the authentication program, as environment variables :
AUTHD_ACCOUNT
AUTHD_PASSWORD
AUTHD_LOCAL_IP
AUTHD_LOCAL_PORT
AUTHD_REMOTE_IP
AUTHD_ENCRYPTED
The authentication program should take appropriate actions to fetch account info according to these arguments, and reply to the standard
output a structure like the following one :
auth_ok:1
uid:42
gid:21
dir:/home/j
end
auth_ok:xxx
If xxx is 0, the user was not found (the next authentication method passed to pure-ftpd will be tried) . If xxx is -1, the user was
found, but there was a fatal authentication error : user is root, password is wrong, account has expired, etc (next authentication
methods will not be tried) . If xxx is 1, the user was found and successfully authenticated.
uid:xxx
The system uid to be assigned to that user. Must be > 0.
gid:xxx
The primary system gid. Must be > 0.
dir:xxx
The absolute path to the home directory. Can contain /./ for a chroot jail.
slow_tilde_expansion:xxx (optional, default is 1)
When the command 'cd ~user' is issued, it's handy to go to that user's home directory, as expected in a shell environment. But
fetching account info can be an expensive operation for non-system accounts. If xxx is 0, 'cd ~user' will expand to the system user
home directory. If xxx is 1, 'cd ~user' won't expand. You should use 1 in most cases with external authentication, when your FTP
users don't match system users. You can also set xxx to 1 if you're using slow nss_* system authentication modules.
throttling_bandwidth_ul:xxx (optional)
The allocated bandwidth for uploads, in bytes per second.
throttling_bandwidth_dl:xxx (optional)
The allocated bandwidth for downloads, in bytes per second.
user_quota_size:xxx (optional)
The maximal total size for this account, in bytes.
user_quota_files:xxx (optional)
The maximal number of files for this account.
ratio_upload:xxx (optional)
radio_download:xxx (optional)
The user must match a ratio_upload:ratio_download ratio.
Only one authentication program is forked at a time. It must return quickly.
OPTIONS -u <uid>
Have the daemon run with that uid.
-g <gid>
Have the daemon run with that gid.
-B Fork in background (daemonization).
-s </path/to/socket>
Set the full path to the local Unix socket.
-R </path/to/program>
Set the full path to the authentication program.
-h Output help information and exit.
EXAMPLES
To run this program the standard way type:
pure-authd -s /var/run/ftpd.sock -r /usr/bin/my-auth-program &
pure-ftpd -lextauth:/var/run/ftpd.sock &
/usr/bin/my-auth-program can be as simple as :
#! /bin/sh
echo 'auth_ok:1'
echo 'uid:42'
echo 'gid:21'
echo 'dir:/home/j'
echo 'end'
