Re: UGLY OFFTOPIC (Re: Fwd: Weird 'free' output)

Guys - even though I didn't receive an answer to my RAM question, I'm happy.
It's really a time machine to the nineties. The only thing I'm missing it's
Marc and a SCSI cable :-)

Re: Weird 'free' output

Omer, thank you!
Is it related to the "Inactive" count from /proc/meminfo?
I used to think that available=free+cache+buffers...

Weird 'free' output

"Available" output seems weird, or I'm missing something?
Any ideas?

Re: Server load spike debugging

[linux.il]

- 1st, I suggest to activate some monitor which save historic data.
You can install 'atop' or config some SaaS monitor.
- How many RAM do you have? Is it dedicated MySQL server or you run
webserver+MySQL?
- I suggest to activate slow query log as well.

Re: OT: Israeli domain names

[linux.il]

I had some domains registered via CCC , service was good.

Hi,

I am a bit late bird, but as my domains start to expire I have to move
them away from ISOC. I thought to give a try to BezeqInt (VirtualNest)
as I don't know any of the others either.

Apparently I cannot do the transfer online. I need to fill out some
paper(!) forms.
I talked to a representative. She told me I will also need to call
them for renewals as that cannot be done via the website either.

Finally she told me the cost is 100 NIS for the transfer and 250 NIS /
2 years for the domain name. I have not seen any of these prices on
their site (I saw there 69 NIS / year) so I was rather shocked.

What is your recommended registrar for Israeli domain names?

 ISOC charges 230 NIS for 2 years but it lists a bunch of others

 some of which charge 70 NIS / year.

 Which one do you use? Are you satisfied? Any horror stories?
 Which one would you recommend?

 I only need the registration service, I manage DNS on my own.

Re: RMS clarifies, backlash was unneeded

[linux.il]

 Moreover, he says the ban imposed on him is NOT Israel in its entirety, but
 only the Universities (the private Shenkar College seems kosher according to
 him). The weird but sensible thing to do is find lecture halls outside the
 universities and there would be no conflict.


So Ariel College should be OK?

Re: problems with syslogd

 5) Google found some similar problem reports, but they all turned out to be
 either filesize overflow (have plenty of place on the /var/ partition btw),
 or crashed daemon.

may be your /var is out of inodes?
