This morning end user complaint that she failed to access to her folder.
After checking I found that my machine didn’t mount to the file server.
Then I try to remount again but it give me “Could not resolve mount point” error message.

[root@ftp ~]#mount -t smbfs -o username=username%password //MyFileServer/SharedFolder /mnt/MountedFolder

Could not resolve mount point /mnt/MountedFolder

After googling I still failed to get a solution.

Then, I listed my /mnt and found that my MountedFolder got problem as below.

[root@ftp mnt]# ls -l /mnt
total 1
?——— 1 root root 4096 Jul 10 11:13 MountedFolder

There was a question mark for the folder mod.
Solution:
reboot the machine then list again the folder

[root@ftp mnt]#ls -l /mnt
total 1
drwxrwxrwx 1 root root 4096 Jul 10 11:13 MountedFolder

Now it was back to normal.
Remount again the folder and can access to the mounted folder now.

It could me many reason you get a “Could not resolve mount point”.
You may googling the solution and mine is one of the solution.
If you had try others solution and can’t work and your mount folder have a “question mark” aslo.
You should try it.

Have a nice day.

I am a network administrator.

There always a lot end users or my friends who have a modem or router which they don’t know their password because the setting was set by ISP’s technician.
Once the Internet service is down, I always is the first person they ask for.
Fortunately, they always keep the default username and password.

A modem/router default password list is important to a network administrator/engineer.

It’s good to list down all the default username and password in my own blog.

I hope this default username and password list is helpful for you.

Below is the list of the default IP, username and password for TMnet Streamyx supported modem/router.

Streamyx (Malaysia) still have the major market share so I just only list down the modem/router supported Streamyx.
If you can’t find your modem  or router’s default username and password above.
You may find yours at the below sites

1. Default Password List – http://www.phenoelit-us.org/dpl/dpl.html
2. Router Passwords – http://www.routerpasswords.com/index.asp
3. Virus.Org Default Password Database – http://www.virus.org/default-password

I have a FACT Accounting for Windows in my environment which is our old accounting system.

We are going to write off all the WinNT and migrate to linux in our environment and it is at the final stage of the migration.
We turn off all the power for power maintenance during last Christmas day.

One of the machine which work as the FACT license server said bye bye to us (failed to power on).
All the clients failed to access to the FACT Accounting for Windows system due to failed to find the license server as below.

What a headache for me, this license server is not setup by me and the person who setup it is not here anymore.
I have no idea at all with this license server so Google always is my good guru.

After googling I found several solutions.

Below is my successful solution.

1. Get a copy of installer from Aladdin.com

2. Extract the installer

3. Run lmsetup.exe and follow the installation’s instruction as below

4. Plug in your toggle then click “Finish” and reboot your machine

5. After reboot, you can found an icon as below.

6. Double click the icon then you can see below windows. It’s running and it’s working now! Done! Successful!

I am using samba file server.
One day, a user told me that he failed to open a shared folder.
Every time he open the shared folder authentication will be prompt.
He still failed to open the shared folder even though he key in the correct user name and password.

After diagnosis I found this error in my /var/log/samba/winbindd.log

more /var/log/samba/winbindd.log
show me this:
idmap Fatal Error: UID range full!! (max: 20000)

Then I googling and finally find the solution. Google always is my GURU. Thanks Google.

Below are the step to fix this problem.

Stop your samba and winbind services

service winbind stop
service smb stop

Delete secrets.tdb and smbpasswd

rm /etc/samba/secrets.tdb
rm /etc/samba/smbpasswd
rm /var/cache/samba/winbindd_idmap.tdb

Ensure “winbind trusted domains only = no” if not just modified it in smb.conf

testparm -v | grep winbind
or
vi /etc/samba/smb.conf

Rejoin the domain

net rpc join -S SERVERNAME -U ADMINISTRATOR%ADMINPASSWORD

Restart winbind service

service winbind start

Ensure can get the user list from domain

wbinfo -u

Fetch list of user accounts and group accounts

getent passwd
getent group

Test the login from another workstation.
Solved!
Job Done!
