Apex DataLoader 22.0 Security Token
Go to Setup| Administration Setup| Security Controls| Network Access
Give starting of your IP address and Ending of your IP address.
For Ex: 220.127.116.11 is your IP address
give Start IP:18.104.22.168
This says that any IP addresses between them can login to Salesforce Easily. After whitelisting it, now you can login to dataloader with your Username and Password. No need of security token here.
Any other ideas?
