Re: [squid-users] SQUID refuses to listen on any TCP Port

[ben]

Hi Eliezer,

It worked! Now I can set my IPV6 input policy back to DROP.Anyway, this 
is my only ipv6-related firewall rules and anything else are defaults. 
Thank you!

I have verified that the Pinger process is at fault.
I don't know if it's a bug or not.
You can disable pinger and it will work:
http://www.squid-cache.org/Doc/config/pinger_enable/

pinger_enable off

will resolve this issue.

All The Bests,
Eliezer

Without seeing the rest of your iptables rules, it's not clear whether this 
really does apply to every interface and every protocol, or whether there
are 
exception rules which over-ride this default policy rule.

However, there are quite a number of applications which will refuse to
start, 
or not operate correctly, if you do not permit loopback traffic (IPv4 as
well as 
IPv6), so this may be the cause of your problems.

Re: [squid-users] SQUID refuses to listen on any TCP Port

[Eliezer Croitoru]

Hey Ben,

As I suspected it's the pinger that is causing this issue.
In my RPM builds it's disabled by defaults to avoid selinux complications.
I think it's a very special case you have found.
Try to use the:
pinger_enable off

and see if it fixes your issue.

Hey Ben,

I do not know if it won't listen.
I can try to reproduce locally and see the results.
I assume it might be related to the pinger process or maybe something else but 
not 100% sure.

Hi Eliezer,

SQUID started listening only after I run "ip6tables -P INPUT ACCEPT". I 
had searched everywhere on the internet regarding this issue and no one 
mentioned that IPV6 iptables rules could stop squid from listening on 
TCP ports. And Squid just started without any complaint. To my limited 
knowledge, it seems no other software behaves like this?
At first I was indeed suspecting that the issue is related to IPV6. 
I had tried recompiling SQUID without IPV6 and disabed IPV6 using 
sysctl.conf, nothing worked. It never occured to me that my IPV6 INPUT 
POLICY could be the culprit.

Hey Ben,

The next step in this situation is to try and connect with netcat from a
remote host and also locally.
 From what I understood the issue was a firewall issue so Squid was
listening.
I can also assume that squid was listening.
Just For future reference:
Try to run the next commands:
sudo netstat -ntlp
sudo ss -ntlp

and send their output to us.
In ubuntu you will not see any "squid" when running plain netstat or ss.

Hello,

I've finally pinpointed the cause. It is my IPV6 iptables rules at 
fault. Once I changed the INPUT policy from DROP to Accept, everything 
works as expected! what a waste of so many hours! Thank you all


Hello,
It could be that squid doesn't like some of my packages(I'm not sure 
which one). I installed the following packages:

  strongswan,nrpe, nagios-plugins

I also tweaked some kernel settings
net.ipv4.ip_forward = 1
net.ipv4.ip_local_port_range = 1 61000
net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_max_tw_buckets = 5000
fs.file-max = 65536
net.core.rmem_max = 67108864
net.core.wmem_max = 67108864
net.ipv4.tcp_rmem = 4096 87380 67108864
net.ipv4.tcp_wmem = 4096 65536 67108864
net.core.netdev_max_backlog = 25
net.ipv4.tcp_mtu_probing = 1
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

I couldn't win her heart back even if I rolled back all these settings 
and removed the packages.


I'm willing to pay if someone can help me resolve this issue

Thank you!

Re: [squid-users] SQUID refuses to listen on any TCP Port

[Eliezer Croitoru]

Hey Ben,

You should try the next test:
install netcat with "apt install netcat"

Then run the next two commands:
netcat -v -l -6 
netcat -v -l -4 

and send us the output of these.
You can change the ports to 3128 which doesn't work and see what might cause
this issue.
It's possible that your VPS hosting service is using a custom kernel or
another thing happens there.
It's not squid by itself that is at fault in this issue since it was tested
on more then one system over the last 10 years including Ubuntu 20.04.

Hi Eliezer,
Thanks for your help. I tried your method. it worked in a few VM

I just have no idea why Squid is so glitchy. same methods, same OS, 
sometimes it did start accepting connection on the specificed TCP port, 
but most of times it didn't. I also tried to install from a PPA repos 
and it is the same story. Any suggestion?

Re: [squid-users] SQUID refuses to listen on any TCP Port

[ben]

Hi Eliezer,
Thanks for your help. I tried your method. it worked in a few VM 
instances but not on others. All have the same version of ubuntu 20.04. 
I just have no idea why Squid is so glitchy. same methods, same OS, 
sometimes it did start accepting connection on the specificed TCP port, 
but most of times it didn't. I also tried to install from a PPA repos 
and it is the same story. Any suggestion?

Hey Ben,

I cannot tell you if there is something wrong with what you are doing or the
OS.
What I did was to install a basic squid on ubuntu 20.4 which comes with
version 4.10.
I shut down the current running suqid.
I took the /etc/squid/squid.conf file and left it with a single line.
After that I started squid with "systemctl start squid" and it seems to work
fine.
I shut down squid and downloaded my version and again left the squid.conf
with a single line.
Just.. adding the mime.conf into /etc/squid/ and it worked like a charm.
Try to use "ss -ntlp" instead of netstat.
You should first try this on a VM on you local desktop in virtualbox or
hyperv.

All The Bests,
Eliezer

Hi Eliezer,

It is a KVM VPS server with ubuntu 20.04. I just reinstalled the whole
operating sytem and started it from scratch but got the same result: No
tcp port listening. I don't know if it is something wrong with the OS
template. Please let me know what I need to do. Thank you!

Hey Ben,

If it doesn't work for you then you are clearly doing something wrong

I can try to give you instructions on how to make it work 100% unless your

setup is messed up or is not a plain ubuntu 20.04.

Is it a simple VM?

Did you wait a few seconds and then killed Squid? Or did Squid quit 
(i.e. gave back control to your terminal/console session) on its own?


It looks like your Squid process is being killed by something: The log 
is missing a debugging line that should have been there right after the 
last line logged. There are no particularly dangerous calls between 
those two debugging lines.


Can you start your Squid from gdb instead of the command line?

sudo gdb --args squid -X -N -d9 -f ...
(gdb) run

There is a difference, but apparently not in the final outcome.

Please use the following or equivalent command to start your Squid 
with debugging enabled (-X), wait ~30 seconds, and then press 
Control-C (to kill the running Squid process if it is running), 
compress, and share a pointer to the resulting stderr output captured

Should "squid -kparse" be of help for such a scenario?


Ideally, but it depends on what the exact cause is. The purpose of 
"-kparse" is to find errors that a startup would show anyway, but 
without actually needing a running proxy.


Nothing being visible at all in cache.log indicates Squid has no 
specific check for the situation yet.




Else then using the default squid.conf it would be helpful to explain what are 
the basic squid.conf that is required for squid to run.
I believe that a wiki/doc about this would be nice (volunteering to write a 
draft later on)



The bundled QUICKSTART file is supposed to be that first-time basic intro.

FYI; wiki is being overhauled by kinkie right now :-). If you do any 
significant update please ping him with details. Cheers

Re: [squid-users] SQUID refuses to listen on any TCP Port

Your Squid output suggests that you are running an SMP Squid. That, in 
turn, suggests that you suffer from an SMP/IPC communication problem.


I suggest the following triage steps:

1. Move your Squid configuration file somewhere else for safekeeping.

2. Write a new configuration file with nothing but some garbage in it. 
For example, you can put an "http_port XXX" line and nothing else. Make 
sure you get a startup error with that configuration file. No Squid 
process should be running. If your Squid still starts OK, then you are 
not using the configuration file you think you are using.


3. Start Squid from the command line, using "-N -d1 -f 
path/to/saved-configuration-file-from-item1.conf" or similar command 
line options and see if you can get your Squid to listen that way. Share 
your results.



HTH,

Alex.

That itself could be the problem.

Please at least use the default config file shown in
, or better use the squid.conf
file built with your custom binary.

Re: [squid-users] SQUID refuses to listen on any TCP Port

[Eliezer Croitoru]

Should "squid -kparse" be of help for such a scenario?
Else then using the default squid.conf it would be helpful to explain what are 
the basic squid.conf that is required for squid to run.
I believe that a wiki/doc about this would be nice (volunteering to write a 
draft later on)

Do you use "workers" in squid.conf? If yes, try temporary setting that 
directive to 1 or starting Squid with "-N" to see whether this is an 
SMP-related problem.


Please share cache.log output that appears when you start Squid. That 
log may be in /var/log, but I am not sure (and it depends, in part, on 
your Squid configuration). If there is no output there, you may need 
to start your Squid by hand and give a "-d1" command line option 
(among others) to see startup output on the console.


Sharing you *_port directives may also be helpful.
