Topic: error messages in /var/log/messages

[Patrick Kessen]

Hi all,

this is a part from the messages logfile, I see some errors with the sl0 interface which I don't understand.
ppp is being used to connect to my ISP. Why is ifconfig sl0 used?

Also I see an error about the module ppp-compress that can't be located. Will this be fixed?

That is how diald works - it creates a fake interface using sl0 in order to intercept packets so that it can transparently bring the ppp connection up and down.

As far as we know, this is harmless, so it's low on our priority list - but we'll get to it eventually.

Best regards,

Add:

alias ppp-compress-21 off
alias ppp-compress-24 off
alias ppp-compress-26 off

to /etc/conf.modules and those messages should go away.
