Bug#556600: getaddrinfo() fails with system error
Hi there. Sorry for the big EMail. Should I use attachments next time? This program works here, I guess your problem is related to your local configuration. That makes sense. The error became apparent after some update, but I honestly can't say what it was that I updated. First of all are you really running libc6 2.10.1-7 or a previous version? Do you know which was the latest working version? === moeb...@perrin:~$ dpkg-query -l libc6 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-==-== ii libc6 2.10.1-7 GNU C Library: Shared libraries === I don't remember which was the lastest working version. I had 2.10.1-5 before, which also didn't work and updated manually to version 2.10.1-7 by downloading the debs from debian.org and installing them (and libc-bin) with dpkg. Since apt-get and aptitude don't work anymore, the latest log entry from my aptitude log may be an indicator. So, 2.9-25 may be the last working version. Is there a place I can get the deb files from to check it? They are not in my archive cache anymore. === Aptitude 0.4.11.11: log report Tue, Nov 10 2009 19:29:53 +0100 IMPORTANT: this log only lists intended actions; actions which fail due to dpkg problems may not be completed.

Bug#556600: getaddrinfo() fails with system error
Hi back. That did it. Thanks a bunch! Now the problem is certainly resolved but why is the error reporting so wrong (EAI_SYSTEM points to errno which does not contain any error information) and why is the fallback not working? Is that related to the [NOTFOUND=return] directive? Anyway, thanks for your input, Hagen. /etc/nsswitch === # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc Name Service Switch' for information about this file. passwd: nis compat group: nis compat shadow: nis compat hosts: nis files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis === Hm, I don't have a NIS configuration here ... only thinking alound.

Bug#556600: getaddrinfo() fails with system error
Package: libc6
Version: 2.10.1-7
Programs which use getaddrinfo() to resolve addresses fail most of the
time. I tried to get to the bottom of the error and came up with the
following little program, that exhibits the error.
test.c
===
#include errno.h
#include stdio.h
#include netdb.h
#include string.h
int main(void)
{
struct addrinfo * result;
int error;
error = getaddrinfo(ftp.de.debian.org, http, NULL, result);
if(error != 0)
{
fprintf(stderr, error in getaddrinfo: %d / %s\n, error,
gai_strerror(error));
if(error == EAI_SYSTEM)
{
fprintf(stderr, system error: %d / %s\n, errno,
strerror(errno));
}
return 1;
}
freeaddrinfo(result);
return 0;
}
===
The output is as follows, which seems wrong in itself to me.
===
error in getaddrinfo: -11 / System error
system error: 0 / Success
===
Now the thing is, when I replace the service string http with NULL,
it works perfectly. But ftp.de.debian.org:http for instance is what
aptitude wants to query and it fails which makes my system
un-upgradable at the moment.
Thanks for your time,
Hagen.
