lory · Apr 15, 2022

May be from version 11 I have this problem:

Code:

root@ns:~ # ping 10.0.0.1
ping: unable to open system.dns service: No such file or directory

But:

Code:

root@ns:~ # /rescue/ping -c 1 10.0.0.1

what is the output of:

 ls -l /usr/lib/libcap_dns*

md5 /lib/casper/libcap_dns.so.2

md5 /sbin/ping

cat /etc/resolv.conf

also if you try ping -n -c1 10.0.0.1 does it works?

You can check with freebsd-update IDS to compare the hash checksums of your files against good know hashes for 13.0

Here how it's look In:

uname -a
FreeBSD squid 13.0-RELEASE-p11 FreeBSD 13.0-RELEASE-p11 #0: Tue Apr 5 18:54:35 UTC 2022 root@amd64-builder.daemonology.net:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64
freebsd-version -uk
13.0-RELEASE-p11
13.0-RELEASE-p11

Code:

root@squid:/lib/casper # ls -l /usr/lib/libcap_dns*
lrwxr-xr-x  1 root  wheel  32 Apr  9  2021 /usr/lib/libcap_dns.so -> ../../lib/casper/libcap_dns.so.2
md5 /lib/casper/libcap_dns.so.2
MD5 (/lib/casper/libcap_dns.so.2) = 22c0c217f23295da9f42cc6713ab5353
root@squid:/lib/casper # md5 /sbin/ping
MD5 (/sbin/ping) = 1eac251140f004a477a6139100122498

Try to rename /usr/lib/libcap_dns.so to /usr/libcap_dns.so.bak and then create a symlink libcap_dns.so -> ../../lib/casper/libcap_dns.so.2

I suspect that your libcap_dns.so.2 incorrectly point to old version of libcap_dns.so and from the man page of libcap_dns you recieve the error for missing system.dns

cap_dns(3)

/* Use Casper capability to create capability to the system.dns service. */
capdns = cap_service_open(capcas, "system.dns");
if (capdns == NULL)
err(1, "Unable to open system.dns service");

Thanks, now everything is ok.
There was a static file, libcap_dns.so.
I remove it and make symlink.

Anyway check using freebsd-update IDS if all programs are with good hashes. Ignore mismatch hashes of configuration files as those files are modified by you at some point after the installation.
