Some internet applications don't work

# ftp
ftp: ftp/tcp: unknown service

# whois google.com
getaddrinfo(whois.crsnic.net): Servname not supported for ai_socktype

I'm thinking there's a general error here. /etc/services does exist so this isn't the problem. Other than that I'm pretty clueless, can anyone please offer their assistance? Thanks.

FUBAR · 2007-08-08 15:31:42

Make sure /etc/services is world readable:

chown root:root /etc/services
chmod 644 /etc/services

Thanks... however this was already the case:

% ls -alF /etc/services
-rw-r--r-- 1 root root 13651 2007-07-30 21:52 /etc/services

FUBAR · 2007-08-09 08:16:42

Does your /etc/services have the line

ftp        21/tcp

?

voidzero · 2007-08-09 09:07:51

% cat /etc/services| grep ftp
ftp-data 20/tcp # default ftp data port
ftp 21/tcp # File Transfer Protocol

FUBAR · 2007-08-10 09:06:27

OK, I'm out.

voidzero · 2007-08-10 09:10:30

Thanks anyway, FUBAR.

Anyone else that could take a shot at helping me?

perhaps you'll find a solution here => http://bbs.archlinux.org/viewtopic.php?id=12437

voidzero · 2007-08-10 09:18:32

Heh, nono ftp is installed (/usr/bin/ftp) it just doesn't work like some other console programs like whois!

Nice useless use of cat!

If you have ftp installed then "man ftp" will tell you all you need to make it work.
I no longer user ftp (as it is insecure) in favor of scp and ssh which allow grater security and all the features you may want, but I remember having to type something like "ftp site_name" and after logging in I would issue a command like "put" to sent files from my system to the server.

Hope this helps.

voidzero · 2007-08-10 19:25:34

Thanks ralvez for your suggestions, however I think the problem is much more plain, and simple, than your suggestions. The problem is:
errors come up when starting ftp.

the error is
ftp: ftp/tcp: unknown service

it happens always.
i do know how to use ftp and the alternatives. It's not what I asked...

I just want a working system and this (together with whois) didn't work from the start.

So please before you answer which I really would love, because this is a very confusing error, at least get the problem before coming with advice that suggests different things.

Now we have this out of the way, let me try to explain the issue once more.

ftp from command line gives the error:
ftp: ftp/tcp: unknown service

whois gives the error:
getaddrinfo(whois.crsnic.net): Servname not supported for ai_socktype

mc does not open valid ftp connections, however, ssh does work. Weird...

/etc/services is correct, does contain ftp 21/tcp and is owned by root:root with modes 644.

Is someone please able to tell me why I am getting these errors? It must be something in the general networking sense, I do have IPv6 configured (auto-config - can't imagine this being the problem).

Thanks guys for helping me

Everything on google is pointing to /etc/services exactly what I'm not sure.
Does services have 43/tcp/upd for whois

Does running the command through strace help further?
strace whois www.google.com

Honestly I really don't know was just trying to help.

voidzero · 2007-08-10 20:39:03

Strace! How could I forget about strace.. silly me.

An ftp strace shows this, I can't make cheese out of it but does it say anything to you?

Honestly I'd love to say I can, but its cheese to me to.

I can do a comparison with whois but not ftp all I can say is I'm getting little mention of locale, in my output any where, but I wouldn't of thought this would be the cause.
The one thing that does stand out is I can't see any resolving or bind but hopefully someone with way more knowledge than I have can assist further.

But what you're getting is so different from myself I really haven't got a clue. If you haven't perhaps set up a locale. Thats what the missing files are, I do have it.

I'm purely guessing I wouldn't of thought this would be it but what do I know and perhaps it might be it.

@voidzero: Sorry, your original post is unclear (at least to me, so with a bad question, you get a bad answer )

Now, to the problem: check /etc/nsswitch.conf and if you see something like "NOTFOUND = return" comment it out to regain ftp connectivity.

Hope this helps.

Have you ran /etc/rc.d/network ?

voidzero · 2007-08-14 19:55:20

Yes ofcourse, test1000,

Ralvez - right now I am using smbldap-tools for ldap stuff, this archlinux install is my client, server is running debian.

#ident $Id: nsswitch.ldap,v 2.4 2003/10/02 02:36:25 lukeh Exp $

# An example file that could be copied over to /etc/nsswitch.conf; it
# uses LDAP conjunction with files.

# "hosts:" and "services:" in this file are used only if the
# /etc/netconfig file has a "-" for nametoaddr_libs of "inet" transports.

# the following two lines obviate the "+" entry in /etc/passwd and /etc/group.
passwd:         files ldap
group:          files ldap

rpc:        ldap [NOTFOUND=return] files
ethers:     ldap [NOTFOUND=return] files

# no support for netmasks, bootparams, publickey yet.
netmasks:   files
bootparams: files
publickey:  files
automount:  files

# I'm pretty sure nsswitch.conf is consulted directly by sendmail,
# here, so we can't do much here. Instead, use bbense's LDAP
# rules ofr sendmail.
aliases:    files
sendmailvars:   files

# Note: there is no support for netgroups on Solaris (yet)
netgroup:   ldap [NOTFOUND=return] files

You think these need modification?

ralvez · 2007-08-14 20:10:49

Hum ... my guess is "yes" because the system that has the setting ON will not respond.
