* [Bug nscd/13375] New: nscd inhibits HOSTALIASES envvar @ 2011-11-02 15:36 matz at suse dot de 2011-11-02 15:38 ` [Bug nscd/13375] " matz at suse dot de ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: matz at suse dot de @ 2011-11-02 15:36 UTC (permalink / raw) To: glibc-bugs http://sourceware.org/bugzilla/show_bug.cgi?id=13375 Bug #: 13375 Summary: nscd inhibits HOSTALIASES envvar Product: glibc Version: 2.14 Status: NEW Severity: normal Priority: P2 Component: nscd AssignedTo: drepper.fsp@gmail.com ReportedBy: matz@suse.de Classification: Unclassified Make sure nscd is running and indeed caching hosts database lookups (not the case with debian for instance), then: % HOSTALIASES=./fooalias strace getent hosts bla 2>&1 | grep fooalias shows that the file isn't accessed. It is accessed if nscd isn't running (and in that case is correctly interpreted). getent is just a convenient shorthand for a testcase, the gethostbyname interface behaves the same, i.e. doesn't lookup HOSTALIASES files when nscd is running. But according to the manpage it should. I think it's an extension, not POSIX behaviour, but one side needs to be fixed, either docu or code. FWIW, the environment variable isn't respected because res_hostalias isn't called, because __libc_res_nquery isn't called, because the nscd-accessing routines are called first. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread

If this is the expected behavior, is there another environment-variable style override to bypass nscd lookup, similar to HOSTALIASES? -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
