I see my proc folder getting bigger and bigger and I have limitation in terms of number of files. Can I delete those files or will it have consequences? thanks Asked by Johan You can not delete them since they are not files. /proc is mounted using the procFS, which is not a real filesystem. Instead the contents are generated the moment you try to read from them. This also means it is not using [...]Continue Reading »

Now if I login as root and issue git commands like git –version I get the response as shown : Code: git version 1.8.1 And I have tried creating repositories as root too and it works fine. Now If I login as just a normal user and if I issue the version command : git –version I [...]Continue Reading »

If My process allocates some big memory and then deallocates, would top or gnome-system-monitor show that my memory usage of that process decreased ? or kernel will still reserve that memory for that process ? What I see is I am deallocating memory. But I still see gnome-system-monitor displaying growing memory for my program. I don’t find memory leak in my end. I want to know whether its not displaying released memory ? or there [...]Continue Reading »
I have a Data General server on unix that is printing a banner page on every print. I originally thought that the banner page was comming from the printer. As this is an HP printer, I used telnet to get to the jetadmin and then proceded to disable the banner page, but this did not solve the issue. I then went into the sysadm program to see if the TCPIP printing was set to print [...]Continue Reading »

So I got gitolite set up. Simple. But there is one issue I am having. The SSH urls follow the format of git@host:repo. I’m used to Bitbucket / Github where the urls follow the format of git@host:user/repo. Is there a way to get the latter format using gitolite? Another question. I have my ~/.ssh/config file set up with the following entry: Host <host> User <user> IdentityFile <path/to/public/key> I don’t have any configuration specifying git as [...]Continue Reading »
Can some proved an argument for and against using centrify? We are currently considering it and I am curious if there are good alternatives to centralize all of our Ubuntu, Red Hat, Solaris servers. The big sell is that fact we do not have to be experts to be on the OS, centrify does that with the agent. Thanks! Asked by rbarrette My info is not current, as it was more than 4 years ago.

Is there a command to tell me what MTA/sendmail a unix system uses? Thanks very much Asked by Alex [root@dev ~]# netstat -tlnp |grep :25 tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1614/sendmail or [root@dev ~]# lsof -n -i :25 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME sendmail 1614 root 4u IPv4 1413591375 0t0 TCP 127.0.0.1:smtp (LISTEN) That should do the trick. If you can’t access the server, telnet to port 25 on it, [...]Continue Reading »
I have many Cisco / JunOS routers and switches that send logs to my Debian server, which uses rsyslogd. How can I configure rsyslogd to send these router / switch logs to a specific file, based on their source IP address? I do not want to pollute general system logs with these entries. For instance: all routers in Chicago (source ip block: 172.17.25.0/24) to only log to /var/log/net/chicago.log. all routers in Dallas (source ip block [...]Continue Reading »
