Bug#1056329: Cannot create simple TCPMUXPLUS service - produces seg fault
Disregard, I did not see in the xinetd.conf manpage that you have to also add the base tcpmux service file.
Bug#1056329: xinetd: Cannot create simple TCPMUXPLUS service - produces seg fault
Package: xinetd
Version: 1:2.3.15.3-1+b1
Severity: important
Dear Maintainer,
I'm trying to create a simple TCPMUXPLUS service that takes a TCP connection
and returns a predetermined amount a entropy.
Here is my xinet.d conf file:
# default: off
# description: An xinetd service which provides entropy.
# the shell script called will return 128 bytes of entropy to the caller.
service entropy
{
id = entropy
type= TCPMUXPLUS UNLISTED
socket_type = stream
protocol= tcp
disable = no
#flags = KEEPALIVE IPv4
instances = 40
server = /srv/xinetd-entropy.sh
log_type= FILE /var/log/entropy-xinetd.log
log_on_success = PID HOST USERID EXIT DURATION
log_on_failure = HOST USERID ATTEMPT
user= nobody
wait= no
}
In this form, restarting xinetd produces this syslog output:

When I comment out the socket_type and protocol lines in the conf (since they
are redundant to type being TCPMUXPLUS), restarting xinetd segfaults:

Bug#1013281: libbatik-java: Running rasterizer fails with inability to load main class org.apache.batik.apps.rasterizer.Main
Package: libbatik-java Version: 1.12-4 Severity: grave Justification: renders package unusable Dear Maintainer, Been using this kind of call against a Jessie install of this package for years: java -jar /usr/share/java/batik-rasterizer.jar -m image/png -scriptSecurityOff -w 1920 /tmp/ramdisk/svgproc-b83e35c457f48904da8a39a01d230d48.svg After upgrading system to bullseye, the same call produces this error: Error: Could not find or load main class org.apache.batik.apps.rasterizer.Main Caused by: java.lang.ClassNotFoundException: org.apache.batik.apps.rasterizer.Main From what I can tell, this was repackaged from having the actual code inside to the jar to being references to other jars. However it looks as if all of the manifests now have a "lib/" prefixed to the classpaths and this causes java to fail at finding any usable source. As a test, I created a symlink called lib inside /usr/share/java/ that simply points back to the same directory. There were still some errors, but it looked like java could at least find some of the other jars it was looking at. This might turn out to be a repackaging problem since the source package on the Apache site does come with all the jars stored into a "lib" directory. -- System Information: Debian Release: 11.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-15-amd64 (SMP w/2 CPU threads) Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libbatik-java depends on: ii java-wrappers 0.3 ii libjaxp1.3-java 1.3.05-6 ii libxalan2-java2.7.2-4 ii libxml-commons-external-java 1.4.01-5 ii libxmlgraphics-commons-java 2.4-2~deb11u1 Versions of packages libbatik-java recommends: ii default-jre 2:1.11-72 Versions of packages libbatik-java suggests: ii librhino-java 1.7.7.2-3 -- no debconf information
