    dns help


    i configured my dns server
    and it is working well
    and its file is
    $ttl 38400
    alvi.com. IN SOA localhost.localdomain. mmohsinalvi.hotmail.com. (
    1111429460
    10800
    3600
    604800
    38400 )
    alvi.com. IN NS localhost.localdomain.
    alvi.com. IN A 192.168.0.1
    alvi.com. IN MX 10 192.168.0.1

    now i changed its 'A' record to

    alvi.com. IN A 192.168.10.1

    now whenever i execute the command
    nslookup alvi.com
    it show the old address 192.168.0.1 instead of 192.168.10.1
    why ?
    may the dns has cache ? how can i disable or refresh its cache


    but when i use webmen application and change the A record the responce is positive
    so reply me on this address
    m_alvi82@hotmail.com

    Did you restart the named daemon after making the change? If not, the change won't be enabled. Webmin does that by default when you change settings and save them.
    There are two major products that come out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence.
