Network problems

Network check

Problem

  • Network connection is not working.

Solution

  • Perform the network check. Use the commands ping, nslookup, address resolution etc. Check the connection with the corresponding SEP sesam access program (CTRL/SSH). The address resolution must be consistent, i.e., if for a TCP/IP name the resolution gives an IP-address, then the resolution for that IP-address must give the same TCP/IP name!

Example

  # nslookup decunix
  Server: seplinux2.sep.de
  Address: 193.28.59.40
  Name: decunix.sep.de
  Address: 193.28.59.94
  # nslookup 193.28.59.94
  Server: seplinux2.sep.de
  Address: 193.28.59.40
  Name: decunix.sep.de
  Address: 193.28.59.94
