A.1.10 Failed to Log in to the System as a Root User While Using FTP (Sun/Solaris)

For the sake of security, FTP service is unavailable to the root user by default after Solaris 8 is installed. To use FTP as a root user, follow this procedure:

Log in as a root user, edit the “/etc/ftpusers” file, comment out the root user line, save the setting, and then log out. Then you can log in as a root user by using FTP.

We recommend that you undo the comment operation after use of the FTP service.

A.1.11 Can’t Use Services Such as Telnet After the NMS is Installed

For the sake of security, when iManager N2000 is installed on Solaris OS, services such as telnet, FTP, finger, and so on, are disabled.

To use these services, follow this procedure:

#cd /etc/inet

#cp inetd.conf inet.conf.bak

#cp inetd.conf.021204.034801.bak inetd.conf

Where the file name "inetd.conf.021204.034801.bak” varies with the date on which the NMS is installed.

View the process used to enable the service and make the process to re-read the file.

#ps -ef | grep inet

root 144 1 0 12 04 ? 0:00 /usr/sbin/inetd -s

#kill -HUP 144

Now, you can use the corresponding services. After use, follow this procedure to disable the services:

#cp inet.conf.bak inetd.conf

#kill -HUP 144

A.1.12 File Size Changed When FTP is Used to Send Files

transmission mode is ASCII. In this case, before sending the files, use the command

“bin” to change the transmission mode to binary format.

A.1.13 Execution Authority of Files is Lost When FTP is Used to Send Files

If the execution authority of Setup is lost when the Setup is copied to a hard disk through FTP program, change the authority of the file. Take the installation script of the NMS as an example, run this command:

# chmod +x setup.sh

If the system prompts that the authority of another file is lost, change it in the same way.

A.2 Database

A.2.1 How to Change the Password of "sa" (Sun/Solaris/Sybase)?

"sa" is the user name of the Sybase system administrator. After the Sybase database is installed, the password of "sa" is null by default. Please follow these steps to set or change the password to "abc123", for example.

$ isql -Usa –P

1> sp_password null, abc123 2> go

The password is set correctly.

(return status=0) 1>quit

The password of "sa" cannot be changed back to null after setting. Please remember the new password.

A.2.3 Sun Workstation Abnormally Shut Down (Sun/Solaris/Sybase)

Use the fsck command to manually check the file system. Log in as a root user and execute the following commands.

1) Execute the fsck -y command to check the file system Input the following command in the terminal window:

# fsck -y

The system begins to correct the errors in the file system until the completion of the correction.

2) If the Sybase database does not start, delete the

"/opt/sybase/N2000DBServer.krg" file (Herein, the N2000DBServer is a Database Server name, which is set while installing Sybase). Then execute the /usr/sbin/shutdown -y -g0 -i6 command to restart the WS.

A.2.4 Unable to Start Sybase(Sun/Solaris/Sybase)

Check the shared memory in the "/etc/system" file for the following contents (usually at the end of this file):

set shmsys:shminfo_shmmax = 131072000

Herein, "131072000" is calculated with the following formula based on the memory of 128M.

Y=X*1024*1000 (where X is the physical memory, measured in MB).

If the set shared memory is lower than the value that is calculated based on the physical memory, the Sybase will fail to be started. Calculate the shared memory on the basis of the physical memory, set it again, and then restart the OS.

A.3 NMS

In the “Login“ dialog box, enter "admin" and "Admin" to log in. For Windows version, both "admin" and "Admin" can log in. For Solaris version, the user "Admin" does not exist, so it cannot log in.

User Manual

HUAWEI iManager N2000 Fixed Network Integrated Management System Appendix A FAQ

I. Solution

In Windows system , user names are case insensitive, so "admin" and "Admin"

indicate the same user. In Solaris system, user names are case sensitive, so "admin"

and "Admin" indicate two different users, and only "admin" can log in.

A.3.13 Device Name Overlap

In the topological view, if the device names are short, they will not overlap after auto layout. If they are very long, they might overlap after auto layout.
