@ -64,11 +64,19 @@ A: ngIRCd does not write its own log file. Instead, ngIRCd uses syslog(3).
Q: I cannot connect to remote peers when I use the chroot option, the
following is logged: "Can't resolve example.com: unknown error!".
A: see next question blow ...
Q: When running ngIRCd inside a chroot, no IP addresses can be translated
in DNS names, errors like "Name or service not known" are logged.
A: On Linux/glibc with chroot enabled you need to put some libraries inside
the chroot as well, notably libnss_dns; maybe others. Unfortunately, even
linking ngIRCd statically does not help this. The only known workaround
is to either disable chroot support or to link against dietlibc instead
of glibc. (tnx to Sebastian Siewior)
linking ngIRCd statically does not help this. So you can either copy
all the required files into the chroot directory:
$ mkdir -p ./chroot/etc ./chroot/lib
$ cp -a /etc/hosts /etc/resolv.conf /etc/nsswitch.conf ./chroot/etc/
$ cp -a /lib/libresolv* /lib/libnss_* ./chroot/lib/
Or you can try to link ngIRCd against an other C library (like dietlibc)
that doesn't depend on NSS modules and/or these files.
Q: I have added an [Oper] section, how do i log on as IRC operator?
A: You can use the /OPER command in your IRC client to become an IRC operator.
