#42918 [NEW]: IPv6 addresses not supported in SNMP extension

From: estesp at fastmail dot us Operating system: Linux PHP version: 5CVS-2007-10-10 (snap) PHP Bug Type: SNMP related Bug description: IPv6 addresses not supported in SNMP extension Description: ------------ The snmp interface code in php5 does not properly support IPv6 addresses for the hostname. Since net-snmp 5.x the SNMP daemon can be listening on udp6 port and therefore, the hostname passed could be a valid IPv6 address. However, the code in the snmp extension has: if ((pptr = strchr (hostname, ':'))) { remote_port = strtol (pptr + 1, NULL, 0); } So, instead of defaulting to the usual (default) snmp port, given an IPv6 address, it is taking everything past the first colon as the port number.. which, I believe is going to give a very interesting port number for most IPv6 addresses :) Reproduce code: --------------- Just call snmpget() with an IPv6 IP address.. you will get a host not found, or similar: $host = '0000:0000:0000:0000:0000:0000:0000:0001'; $community = 'public'; $sysName = snmpget($host, $community, "system.sysName.0"); print "$sysName Expected result: ---------------- snmpget() should work for IPv6 addresses given you have a net-snmp version with IPv6 support and have snmpd listening on an IPv6 transport. Actual result: -------------- PHP Warning: snmpget(): Could not open snmp connection: Unknown host (0000:0000:0000:0000:0000:0000:0000:0001) in /my_ipv6_php on line 4 There may be other issues here as "unknown host" sounds like a getaddrinfo problem, but since doing an snmpget on the server in Ipv6 mode outside of php5 works, I have to bet that something in the snmp interface in php5 is broken with respect to IPv6. -- Edit bug report at http://bugs.php.net/?id=42918&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42918&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42918&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42918&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42918&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42918&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42918&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42918&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42918&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42918&r=support Expected behavior: http://bugs.php.net/fix.php?id=42918&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42918&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42918&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42918&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42918&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42918&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42918&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42918&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42918&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42918&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42918&r=mysqlcfg
