Yuri,

 

I am new to squid I learned it through searching google. My question is I generated self-signed SSL certificates and install certificates on IE all clients. I didn’t install proxy public key. Can you tell me where  I have to put proxy public key on clients. Appreciate you help!

Ah. Based on my experience,

you require to take *public* proxy key (not private, your use keypair to setup ssl-bump configuration; do not mistake it) and install it at least into two places on client's PC:

1. Into system trusted CA storage (uses by IE/Chrome/some IM etc.)
2. Into Firefox own storage (if applicable).
3. Sometimes it is also required to setup proxy's CA public key into old JRE existing on clients. But AFAIK modern JRE uses system CA's storage and no more required this step.

Actually, this should be enough.

 

Thanks,

Naresh

Related OpenSSL public CA bundle - in theory it should be installed together with OpenSSL.

Thanks Yuri for quick turnover!

 

We inly installed root certificate on all clients. We didn’t install proxy CA’s public key on clients. So you suggestion fix that we need to install both certificate and proxy ca’s public key on clients.

 

Thanks,

Naresh

One out of two. Either the Squid does not see the OpenSSL/system root CAs bundle, or the proxy CA's public key is not installed in the clients. It's all.

Hello,

this seems not to be the problem, as the error messages are in cache.log, which is not a browser problem ...

the question: are the SSL bumped sites in intranet, which use a self signed CA cert itself, which squid doesn't know?

Hi All,

 

I installed Squid version 3.5.20 on RHEL 7 and generated self-signed CA certificates,  My users are complaining about certificate errors. When I looked at cache.log I see so many error messages like below. Below is my squid.conf file. Any ideas how to address below errors.

 

Cache.log
