PQ74543: PING TREATS IP ADDRESSES WITH LEADING ZEROES AS OCTAL NUMBERS INSTEAD OF DECIMAL NUMBERS.

APAR status

• Closed as fixed if next.

Error description

• Ping treats IP addresses with leading zeroes as octal numbers.
  A ping of IP address 9.017.3.4 will result in a ping being
  sent to IP address 9.15.3.4.  Ping is using the C library call
  inet_addr to convert the IP address into a in_addr structure.
  inet_addr interprets number with leading zeroes as octal. Ping
  should be using inet_pton, which does not do this conversion.
  .
  KEYWORDS:
  ping oping timeout time out
  

Local fix

• Do not use leading zeroes when entering IP addresses on the
  ping command.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the IBM Communications Server   *
  *                 for z/OS Version 1 Release 4 IP: PING.       *
  ****************************************************************
  * PROBLEM DESCRIPTION: If an user attempts to PING an IP       *
  *                      address that contains a leading         *
  *                      zero, that request will time out.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The attempt to PING an IP address that contains a leading
  zero will possibly time out because the portion of the IP
  address that contains a leading zero will be converted to
  an octal number.
